The moment a legal claim is considered to have arisen, which is when the statute of limitations clock typically begins to run. For most personal injury claims this is the date of the injury, though it can be delayed under the discovery rule when the harm is not immediately apparent.
Example: If a driver is rear-ended on June 1, the cause of action ordinarily accrues on June 1 and the limitations period starts that day.
The value of a vehicle or property immediately before the loss, calculated as replacement cost minus depreciation. ACV — not what the owner originally paid — is typically what an auto insurer will pay for a totaled vehicle.
Example: A five-year-old sedan purchased new for $30,000 may have an ACV of $14,000 at the time of a total-loss collision.
An insurance-company employee or contractor who investigates a claim, evaluates damages, and decides what (if anything) the insurer will pay. Staff adjusters work for one insurer; independent adjusters work for multiple insurers; public adjusters work for policyholders.
Example: After a fender-bender, the at-fault driver's insurer assigns an adjuster to inspect the damaged car, review medical bills, and extend a settlement offer.
The worsening of a prior medical condition because of a new accident. Aggravation is fully compensable: under the eggshell-plaintiff rule, the defendant is liable for the difference between the plaintiff's pre-accident condition and their post-accident condition, even when the underlying condition existed before the crash.
Example: A person with controlled degenerative disc disease who is rear-ended and then requires fusion surgery can recover for the aggravation — not the underlying disease, but the worsening the crash caused.
The defendant's formal written response to a complaint, in which each allegation is admitted, denied, or said to be unknown. Affirmative defenses (e.g., comparative fault, statute of limitations) are also raised in the answer.
Example: After being served with a personal injury complaint, the defendant has a deadline (typically 20–30 days) to file an answer.
A request that a higher court review the decision of a lower court for legal error. Appeals usually do not re-try the facts; they review whether the law was applied correctly.
Example: After a defense verdict, a plaintiff may appeal a trial-court ruling that excluded key expert testimony.
A private out-of-court dispute-resolution process in which a neutral arbitrator (or panel) hears evidence and issues a decision. Arbitration can be binding (final) or non-binding (advisory).
Example: Many auto policies require disputes over uninsured-motorist benefits to be resolved through arbitration rather than a jury trial.
A defense arguing the injured person knowingly and voluntarily accepted a known danger, reducing or barring recovery. Most states today fold this concept into comparative-fault analysis rather than treating it as a complete bar.
Example: A spectator hit by a foul ball at a baseball game may be found to have assumed the inherent risks of attending the game.
A legal rule that protects confidential communications between a client and lawyer made for the purpose of obtaining legal advice. The privilege belongs to the client and generally survives the attorney-client relationship.
Example: What you tell your personal injury lawyer about how the accident happened — even unfavorable facts — cannot be revealed to the insurance company without your consent.
A lawyer's right to be paid out of the proceeds of a client's settlement or judgment for fees and costs advanced on the case. The lien attaches to the recovery and is typically created by the fee agreement.
Example: After a $100,000 settlement, the attorney's lien is satisfied from the gross recovery before the client receives the net.
A doctrine that holds landowners liable for injuries to children drawn onto property by a dangerous artificial condition the owner should have known would attract them. Most commonly applied to swimming pools, abandoned appliances, and construction sites.
Example: An unfenced backyard pool that a neighborhood child wanders into and drowns in can trigger attractive-nuisance liability even though the child was technically trespassing.
↑ Back to A-ZAn insurer's unreasonable refusal to honor its obligations under a policy — for example, denying a covered claim without proper investigation, lowballing a clear-liability case, or failing to settle within policy limits when it could. Bad-faith claims can expose insurers to damages beyond the policy limit, sometimes including punitive damages.
Example: A carrier that ignores its insured's repeated requests to settle a clearly liable injury claim within the $100,000 policy limit, then takes the case to trial and loses a $1 million verdict, may face a bad-faith claim for the excess.
Jurisdictional Note: Recognized in different forms across CA, TX, and WA; statutory bad-faith and unfair-claims-practices statutes vary by state.
The highest standard of proof in U.S. law, required to convict in a criminal case. It does not apply in personal injury cases — civil claimants need only prove their case by a preponderance of the evidence.
Example: A drunk driver may be acquitted of a criminal DUI charge ("beyond a reasonable doubt") yet still be liable for injuries in a civil suit ("more likely than not").
Splitting a trial into two or more separate phases — for example, deciding liability first and damages second. Bifurcation is intended to streamline trials and can be ordered by the court.
Example: In a punitive-damages case, the jury may first decide compensatory damages and only later hear evidence about the defendant's net worth.
A device installed in most modern vehicles that records data such as speed, braking, steering input, throttle, seatbelt status, and airbag deployment in the seconds before and after a crash. EDR data is increasingly important evidence in serious-injury cases.
Example: EDR data showing a defendant was traveling 72 mph in a 35-mph zone two seconds before impact can be powerful evidence of liability and recklessness.
Auto-insurance coverage that pays others for injuries caused by the policyholder's negligent driving — including medical bills, lost wages, and pain and suffering — up to the policy limit. State minimums are commonly written as split limits like "25/50" (per person / per accident in thousands).
Example: A 25/50 BI policy pays up to $25,000 to any one injured person and up to $50,000 total for all injuries from one accident.
Jurisdictional Note: Minimum required limits vary by state. CA requires 15/30; TX requires 30/60; WA requires 25/50.
The second element of a negligence claim: the defendant failed to act as a reasonably careful person would under the circumstances. A breach can be an action (texting while driving) or an omission (failing to repair a known hazard).
Example: A grocery store that knew about a spilled liquid for 30 minutes and did not clean it or warn shoppers has breached its duty of care.
The obligation a party has to prove its claims to a specified degree of certainty. In personal injury cases, the plaintiff carries the burden and must meet the preponderance-of-the-evidence standard.
Example: If the evidence is exactly 50/50, the plaintiff has not met the burden of proof and the defendant wins.
A claim by a close family member who suffers emotional distress from witnessing a serious injury or death of a loved one. Most states impose strict limits, such as physical proximity to the event and a close relationship to the victim.
Example: A parent who watches a child get struck by a speeding driver may have a bystander claim for negligent infliction of emotional distress.
Jurisdictional Note: California recognizes bystander claims under Dillon v. Legg and Thing v. La Chusa. Many states have similar but stricter rules.
↑ Back to A-ZA severe injury that permanently prevents a person from returning to gainful work or substantially alters daily life — typically traumatic brain injury, spinal-cord injury, severe burns, amputations, multiple-organ damage, blindness, or significant disfigurement. Catastrophic-injury cases generally involve a life-care plan, vocational-expert testimony, and multi-million-dollar future-medical and future-wage-loss components.
Example: A high-cervical spinal-cord injury producing tetraplegia is a catastrophic injury that can require 24-hour attendant care, home modifications, lifelong medical management, and a life-care plan running into the eight figures.
A medical determination that a specific injury or condition was caused by — and is fairly traceable to — the accident in question. Insurers often dispute causation when there is a pre-existing condition or gap in treatment.
Example: An MRI documenting a new disc herniation soon after a rear-end collision supports the conclusion that the injury is causally related to the crash.
The link between the defendant's conduct and the plaintiff's injury. Courts analyze two layers: (1) cause-in-fact ("but for" the conduct, would the injury have occurred?) and (2) proximate cause (was the injury a foreseeable consequence?).
Example: But for the driver running the red light, the pedestrian would not have been hit. The pedestrian's broken leg is also a foreseeable result of being struck.
Wireless-carrier billing records and metadata showing calls placed, texts sent, data sessions, cell-tower connections, and (sometimes) location at given times. In distracted-driving cases, cell-phone records are routinely subpoenaed to prove whether a driver was using a phone in the seconds before a crash.
Example: A subpoena to a carrier may show the at-fault driver sent a text three seconds before impact — powerful evidence of negligence and, in some states, recklessness supporting punitive damages.
A demand for compensation submitted to an insurance company or another party. A claim may be a first-party claim (against your own insurer) or a third-party claim (against another person's insurer).
The person making an insurance claim. If the dispute ends up in court, the claimant typically becomes the "plaintiff."
A middle standard of proof, higher than preponderance but lower than beyond a reasonable doubt. Many states require clear and convincing evidence to recover punitive damages and to prove fraud.
Example: To win punitive damages against a drunk driver in many states, the plaintiff must show by clear and convincing evidence that the conduct was malicious or reckless.
First-party auto-insurance coverage that pays to repair or replace your own vehicle after a collision, regardless of who was at fault. It is subject to a deductible.
Example: If you back into a pole, collision coverage pays repair costs above your deductible even though no other driver was involved.
An insurance policy issued to a business rather than an individual, generally with substantially higher liability limits and specialized endorsements for owned vehicles, employees, contractors, and business operations. Commercial motor carriers operating in interstate commerce face federal minimum-coverage requirements set by the Federal Motor Carrier Safety Administration that far exceed personal-auto minimums.
Example: For-hire interstate trucking carriers hauling general freight must maintain at least $750,000 in liability coverage under 49 C.F.R. § 387.9 (higher minimums apply to passenger carriers and to carriers hauling certain hazardous materials).
An equitable rule that reduces a lienholder's reimbursement to reflect its fair share of the attorney's fees and costs that created the recovery. In effect, those who benefit from the lawyer's work help pay for it.
Example: A health insurer asserting a $30,000 lien against a $90,000 settlement may have its lien reduced by one-third (the contingency fee) plus a share of costs under the common fund doctrine.
A fault rule under which the plaintiff's recovery is reduced by their own percentage of fault, even if that percentage is very high. A plaintiff who is 80% at fault can still recover 20% of damages.
Example: In a $100,000 case where the plaintiff is 30% at fault, the plaintiff recovers $70,000.
Jurisdictional Note: Pure comparative negligence is the rule in California and Washington. Texas uses modified comparative negligence with a 51% bar.
Money awarded to compensate an injured person for actual losses — both economic (medical bills, lost wages) and non-economic (pain and suffering). The goal is to make the plaintiff whole, not to punish.
The document that starts a civil lawsuit. It identifies the parties, alleges the facts, states the legal claims, and asks the court for specific relief.
Example: A car-accident complaint typically names the at-fault driver as defendant, alleges negligent driving, and demands compensatory damages.
Jurisdictional Note: In Texas, the same document is called a "petition."
First-party auto-insurance coverage for non-collision damage — theft, vandalism, falling objects, fire, glass breakage, animal strikes, and weather damage. It is subject to a deductible.
Example: Comprehensive pays to replace a windshield cracked by a flying rock or to repair hail damage.
A type of mild traumatic brain injury caused by a bump, blow, or jolt to the head — including a sudden whiplash motion — that briefly disrupts normal brain function. Symptoms include headache, confusion, dizziness, memory problems, and light sensitivity, and may persist for weeks or longer.
Example: A driver whose head strikes the steering wheel in a low-speed crash may suffer a concussion even if imaging studies appear normal.
A payment Medicare makes for accident-related medical care when another payer (an auto insurer or liability carrier) may be responsible. The payment is "conditional" because it must be repaid to Medicare from any settlement, judgment, or award.
Example: After a crash, Medicare may pay an injured beneficiary's hospital bill conditionally; once a liability settlement is reached, that amount must be reimbursed to CMS.
A provision in a settlement agreement that bars one or both parties from disclosing the terms of the settlement (and sometimes the underlying facts). Defendants and insurers frequently insist on confidentiality.
Example: A confidentiality clause may prohibit a plaintiff from posting the settlement amount on social media.
An attorney fee arrangement under which the lawyer is paid a percentage of the client's recovery rather than an hourly rate. If there is no recovery, there is no fee. Personal injury cases are predominantly handled on contingency.
Example: On a 33â…“% contingency, a $90,000 settlement yields a $30,000 attorney fee plus reimbursement of case costs, with the remainder paid to the client (less any liens).
A harsh older rule under which any fault on the plaintiff's part — even 1% — completely bars recovery. Only a handful of jurisdictions (Alabama, Maryland, North Carolina, Virginia, and Washington, D.C.) still apply pure contributory negligence.
Example: In a pure contributory-negligence state, a pedestrian who is 5% at fault for jaywalking recovers nothing from a speeding driver.
An insurer's formal refusal to pay all or part of a claim on the ground that the loss is not covered by the policy. Most states require denials to be communicated in writing with a specific policy basis. Improper or pretextual denials can support a bad-faith claim and, in some states, statutory penalties.
Example: An insurer may deny a claim because the policy lapsed for non-payment, the driver was excluded by name, or the use of the vehicle falls within an exclusion such as racing or commercial delivery.
A claim filed by a defendant against the plaintiff in the same lawsuit. In an auto case, a defendant may counterclaim for their own injuries or property damage.
A claim filed between co-parties on the same side of a lawsuit (e.g., one defendant suing another defendant) for indemnification or contribution.
↑ Back to A-ZMoney the court orders a wrongdoer to pay to an injured party. Damages can be compensatory (economic and non-economic), punitive, or nominal.
A small camera mounted in a vehicle that continuously records video — and often audio and GPS data — of the road and sometimes the cabin. Dash-cam footage is frequently the single most valuable piece of evidence in a car-accident case because it removes ambiguity from witness accounts.
Example: A defendant's dash cam may show the plaintiff stopping suddenly, supporting comparative fault; a plaintiff's dash cam may show the defendant running a red light at the moment of impact.
The date the accident or injury occurred. The date of loss is the starting point for the statute of limitations in most personal injury cases.
The front page of an insurance policy summarizing key facts: named insured, covered vehicles, coverages, limits, deductibles, premium, and policy period. It controls a great deal of what the policy will and will not pay.
Example: A dec page might show $100,000/$300,000 BI limits, $50,000 PD, $25,000 UM, and a $500 collision deductible.
The amount the policyholder must pay out of pocket before insurance starts paying on a covered loss. Higher deductibles generally mean lower premiums.
Example: If a windshield repair costs $700 and the comprehensive deductible is $250, the insurer pays $450 and the policyholder pays $250.
A judgment entered against a defendant who fails to answer the complaint or otherwise appear in the lawsuit. Defaults are usually set aside only on a showing of good cause.
A court ruling that determines the legal rights and obligations of the parties without awarding damages or ordering specific action. In personal-injury matters, declaratory-judgment actions are most commonly used to resolve disputes about insurance coverage — for example, whether a particular policy applies to a particular loss.
Example: A liability insurer that believes its "business-use" exclusion bars coverage may file a declaratory-judgment action asking the court to rule on coverage before the underlying tort case proceeds.
The party being sued in a civil case. In a personal injury matter, the defendant is the person, business, or government entity the plaintiff alleges caused the harm.
A formal letter from the injured party or their lawyer to the at-fault party's insurer, setting out the facts, liability theory, injuries, treatment, damages, and a specific settlement demand. Most personal injury cases begin to resolve from a well-supported demand.
Example: A demand may attach medical records, bills, wage-loss documentation, and photographs, then request the policy limit based on the strength of the claim.
Sworn out-of-court testimony given before trial, recorded by a court reporter, with lawyers for each side present. Deposition testimony can be used to impeach a witness at trial or, in some cases, read into the record.
Example: A defense lawyer may depose the plaintiff for several hours about the accident, prior injuries, medical treatment, and the impact on daily life.
The loss in market value of a vehicle after it has been damaged and repaired, because buyers typically pay less for a previously wrecked car. Recoverability and method of calculation vary by state.
Example: A two-year-old SUV worth $40,000 pre-accident may be worth only $34,000 after high-quality repairs — a $6,000 diminished-value claim.
Jurisdictional Note: First-party diminished-value claims are recognized in different ways across CA, TX, and WA.
The pretrial phase in which each side gathers evidence from the other side and from third parties. Tools include interrogatories, requests for production, requests for admission, depositions, and subpoenas.
A doctrine that delays the start of the statute of limitations until the plaintiff knew, or with reasonable diligence should have known, about the injury and its cause. Frequently applied to medical malpractice and latent injuries.
Example: A surgical sponge left inside a patient might trigger the limitations clock only when the patient discovers it on a later scan — not on the date of surgery.
Liability of a dog owner for injuries inflicted by the dog. Many states impose strict liability — meaning the victim does not have to prove negligence or prior viciousness. Others follow a "one-bite" rule that requires prior notice of the dog's dangerous tendencies.
Jurisdictional Note: California (Civ. Code § 3342) imposes strict liability on dog owners for bites in public places or while the victim is lawfully on private property. Texas largely follows the one-bite rule; Washington has a strict-liability statute (RCW 16.08.040).
A theory of liability that allows an injured person to sue a bar, restaurant, or social host for overserving alcohol to an obviously intoxicated person who then caused harm.
Jurisdictional Note: Texas has a Dram Shop Act (Alcoholic Beverage Code Chap. 2). California recognizes very narrow dram-shop liability primarily for serving obviously intoxicated minors. Washington recognizes dram-shop liability under common law and statute.
Acronyms for criminal offenses involving impaired driving — Driving Under the Influence, Driving While Intoxicated, or Operating Under the Influence. A criminal DUI does not by itself decide a civil case but can powerfully support a negligence (and sometimes punitive-damages) claim.
Example: A driver convicted of DUI for a crash may face both criminal penalties and a separate civil lawsuit by the injured party.
The legal obligation to act with reasonable care toward others. Drivers owe a duty to drive safely; property owners owe a duty to keep premises reasonably safe; doctors owe their patients a professional standard of care.
↑ Back to A-ZDamages that have a verifiable dollar value: past and future medical expenses, lost wages, lost earning capacity, property damage, household services, and out-of-pocket costs.
Example: $42,300 in medical bills + $8,000 in lost wages + $6,500 in vehicle damage = $56,800 in economic damages.
A long-standing rule that a defendant "takes the plaintiff as they find them" — meaning a defendant is liable for the full extent of injuries even if the plaintiff was unusually fragile or had a pre-existing condition that worsened the harm.
Example: A minor rear-end collision that causes severe disc herniations in a plaintiff with degenerative disc disease is still fully compensable.
Mental suffering caused by an injury or by witnessing harm, recoverable as part of non-economic damages. Stand-alone claims for negligent or intentional infliction of emotional distress are also possible in certain situations.
A written change to an insurance policy that adds, removes, or modifies coverage. Endorsements override conflicting language in the base policy.
Example: Adding a teenage driver, removing a sold vehicle, or buying rental-car reimbursement coverage are all done via endorsement.
A reimbursement claim asserted by a self-funded employer health plan governed by the federal Employee Retirement Income Security Act of 1974 (ERISA). ERISA plans often have aggressive subrogation rights that can sidestep state anti-subrogation rules.
Example: A self-funded employer health plan that paid $50,000 of accident-related medical care may assert an ERISA lien against the injured employee's third-party settlement.
Insurance that pays only after the underlying primary policy's limits have been exhausted. Excess policies typically "follow form," meaning they adopt the underlying policy's terms and exclusions rather than broadening coverage. Excess and umbrella coverage are often confused, but umbrella policies generally provide broader coverage than a true excess policy.
Example: An at-fault driver with a $250,000 primary auto BI limit and a $1,000,000 excess auto policy has up to $1,250,000 of total auto-liability coverage available.
See Black Box. The federal regulation governing EDRs is 49 C.F.R. Part 563. Crash investigators routinely download EDR data through the OBD-II port.
Specific situations, persons, or losses the insurance policy does not cover. Common auto exclusions include intentional acts, racing, and use of the vehicle for commercial delivery (unless endorsed).
Example: An auto policy may exclude coverage for damage caused while delivering food for pay unless the policyholder buys a rideshare/delivery endorsement.
A specialist who is qualified by knowledge, skill, training, or education to give opinion testimony beyond ordinary common knowledge. Common personal injury experts include accident reconstructionists, biomechanical engineers, treating physicians, life-care planners, and forensic economists.
↑ Back to A-ZIn an insurance setting, the policyholder. A "first-party" claim is one filed against one's own insurer (for example, a UM/UIM claim or a collision claim).
The legal concept that a defendant is liable only for harms a reasonable person would have anticipated as a possible result of their conduct. Foreseeability shapes both duty and proximate cause.
Example: It is foreseeable that running a red light might injure another driver. It is generally not foreseeable that the noise from the crash would startle a faraway bicyclist into a separate fall.
The reasonable cost of medical treatment the injured person is more likely than not to need in the future, often supported by physician testimony and a life-care plan. Future expenses are typically reduced to present value.
Example: A traumatic brain injury that will require lifelong neuropsychology visits, medications, and home-care services can drive future-medical components into the millions of dollars.
↑ Back to A-ZA post-judgment collection tool that diverts a portion of the judgment debtor's wages or seizes funds from their bank account to satisfy the judgment.
A required pre-lawsuit filing when the defendant is a government entity (city, county, state, transit district, school district). Failing to file in time generally bars the claim entirely.
Jurisdictional Note: In California, claims against public entities must be presented within six months under the Government Claims Act (Gov. Code § 911.2). Texas has the Tort Claims Act with strict notice rules; Washington requires a tort-claim form before suit (RCW 4.92 / 4.96).
A degree of negligence greater than ordinary carelessness — conduct that shows a serious disregard for the safety of others. Gross negligence is often required to recover punitive damages and to overcome certain immunities.
Example: A trucking company that knowingly dispatches a driver with multiple recent DUIs may face gross-negligence and punitive-damages exposure.
↑ Back to A-ZA crash in which the fronts of two vehicles strike each other, typically caused by a driver crossing the centerline. Head-on crashes have disproportionately high fatality rates.
An out-of-court statement offered in court to prove the truth of its content. Hearsay is generally inadmissible, but there are many exceptions (e.g., statements made for medical diagnosis, excited utterances, business records).
Example: A witness's testimony that "a bystander told me the white pickup ran the light" is hearsay if offered to prove the pickup ran the light.
Compensation for the diminished ability to enjoy life's normal activities — hobbies, exercise, travel, intimacy, and other pleasures lost because of the injury. In many states this is part of pain-and-suffering rather than a separate category.
Example: A formerly avid hiker who can no longer hike after a knee injury may recover hedonic damages for that loss.
A crash in which a driver leaves the scene without identifying themselves or reporting the accident as required by law. Hit-and-run is a separate criminal offense and is also typically covered under uninsured-motorist (UM) coverage when the at-fault driver cannot be identified.
A contract provision in which one party agrees to absorb the other's liability for specified risks. In settlement, the plaintiff often agrees to hold the defendant and insurer harmless from medical or other liens.
↑ Back to A-ZA standardized diagnostic code used by U.S. healthcare providers and insurers (e.g., S13.4XXA, sprain of cervical spine, initial encounter). ICD-10 codes appear on medical bills and records and are routinely scrutinized in injury claims.
A worker hired to perform a task but not subject to the day-to-day direction and control of the hiring party. Unlike employees, independent contractors generally do not create respondeat-superior liability for the hiring party — though exceptions exist for non-delegable duties, retained control, negligent hiring, and inherently dangerous activities.
Example: A pizzeria can usually be held vicariously liable for an employee delivery driver's negligence; liability is far more limited if the driver is properly classified as an independent contractor.
Jurisdictional Note: California Labor Code § 2775 (codifying the Dynamex "ABC test" and AB 5) makes worker classification more plaintiff-friendly. Texas and Washington use multi-factor common-law tests focused on the right to control.
A promise by one party to compensate another for losses. Settlement agreements often include indemnity language requiring the plaintiff to repay the defendant if a third party later asserts a lien against the settlement.
A medical examination of the plaintiff by a physician chosen (and paid) by the defense or insurer. IMEs are common in litigated injury and workers' compensation cases and are often disputed because the examining doctor is not the patient's treating physician.
Example: A defense IME doctor may opine that the plaintiff's back symptoms are unrelated to the crash and instead reflect long-standing degeneration.
The person or entity to whom an insurance policy is issued and whose name appears on the declarations page. Other people (resident relatives, permissive drivers) may also be covered depending on policy language.
The insurance company that issued the policy and is responsible for paying covered claims. Also called the "carrier."
A civil wrong committed on purpose, such as assault, battery, false imprisonment, or intentional infliction of emotional distress. Intentional torts are usually not covered by general auto-liability insurance.
Written questions sent from one party to another that must be answered in writing under oath. Used heavily in personal injury cases to learn about prior accidents, medical history, witnesses, and damages.
↑ Back to A-ZA post-trial ruling in which the judge overturns a jury verdict because no reasonable jury could have reached it on the evidence. Rarely granted.
A rule that lets a plaintiff collect the entire judgment from any one of multiple defendants found liable, leaving the defendants to sort out their respective shares among themselves.
Jurisdictional Note: California limits joint-and-several liability to economic damages (Prop 51). Texas applies it only to defendants found more than 50% at fault.
The court's final decision in a case. A money judgment is enforceable through liens, garnishments, and other collection tools.
The written rules of law a judge gives the jury before deliberations, telling jurors how to apply the law to the facts. Pattern instructions (CACI in California, PJC in Texas, WPI in Washington) form the starting point in most cases.
↑ Back to A-ZA written agreement between an injured patient (and typically their attorney) and a healthcare provider in which the provider agrees to treat the patient now and accept payment later out of any settlement or judgment. LOPs allow injured people without health insurance, or who cannot pay up front, to obtain care while their case is pending. They create a lien-like interest in the eventual recovery.
Example: An uninsured crash victim may obtain MRI imaging and pain-management injections on an LOP basis while the third-party liability claim is being negotiated.
Jurisdictional Note: Widely used in Texas, Florida, and California. Some states regulate LOP arrangements through court rules, disclosure requirements, or limits on attorney involvement to prevent abuse.
A legal claim against money or property to secure payment of a debt. Common personal-injury liens are health-insurance liens, hospital liens, Medicare/Medicaid claims, and attorney's liens.
A detailed expert report projecting the future medical care, equipment, therapy, attendant care, and other lifetime costs the injury will require. Life-care planners are typically nurses or certified rehabilitation specialists.
Example: A life-care plan for a high spinal-cord injury can run hundreds of pages and produce a present-value figure in the millions of dollars.
A claim brought by the spouse (and in some states, the children or parents) of a seriously injured person for the loss of love, affection, companionship, intimacy, household services, and society.
Example: If a spouse is left bedridden after a crash, the other spouse may bring a loss-of-consortium claim alongside the primary injury case.
The reduced ability to earn money in the future because of the injury. Different from past lost wages — it looks forward at the career trajectory the plaintiff is no longer able to pursue.
Example: A 28-year-old electrician with a permanent shoulder impairment may lose decades of higher-earning years.
Income the plaintiff actually lost as a result of the injury — paychecks, overtime, bonuses, tips, and self-employment earnings — typically proven with pay stubs, tax returns, and an employer's letter.
Payment of the entire settlement amount at once, rather than in installments. Most personal injury settlements are paid lump-sum, but structured settlements are common in catastrophic-injury and minor's cases.
↑ Back to A-ZAn equitable rule limiting an insurer's right to be reimbursed from a third-party recovery until the injured insured has been fully compensated (made whole) for their loss. Recognition and strength of the doctrine vary by state and can be overridden by clear policy language.
The point at which an injured person's condition is not expected to improve further with additional medical treatment. MMI is significant for valuing future-medical and permanent-impairment damages.
Example: Once a treating physician declares MMI, the focus shifts from active treatment to maintenance care and disability ratings.
A confidential, voluntary settlement process led by a neutral mediator who facilitates negotiation between the parties. The mediator does not decide the case; the parties remain in control of any settlement.
Example: Many personal injury cases settle at mediation after discovery is largely complete and each side has tested the other's evidence.
A claim by a hospital, doctor, or chiropractor against the proceeds of the patient's third-party recovery, securing payment for treatment provided.
Jurisdictional Note: California Hospital Lien Act (Civ. Code §§ 3045.1–3045.6) caps and regulates hospital liens. Texas hospital liens are governed by Property Code Chapter 55.
Optional first-party auto-insurance coverage that pays medical bills for the policyholder, passengers, and household members after a crash, regardless of fault. MedPay limits are usually modest ($1,000–$25,000) and there is no deductible.
Example: After a crash, a policyholder might use $5,000 in MedPay to cover ambulance, ER, and follow-up bills while the liability claim against the at-fault driver is pending.
An allocation of settlement funds intended to pay for future Medicare-covered, injury-related medical care. The funds must be spent before Medicare will pay for related future treatment. MSAs are routine in workers' compensation and are increasingly considered in liability cases involving Medicare beneficiaries.
The injured party's legal duty to take reasonable steps to limit their losses — most often by getting recommended medical treatment and returning to work when medically able. Failure to mitigate can reduce recoverable damages.
Example: A plaintiff who refuses recommended physical therapy and whose injuries then worsen may have damages reduced for failure to mitigate.
A fault rule that allows recovery only if the plaintiff's share of fault is below a defined threshold. In a "51% bar" state, the plaintiff loses if they are 51% or more at fault.
Jurisdictional Note: Texas uses a 51% bar (Civ. Prac. & Rem. Code § 33.001). California and Washington use pure comparative negligence — no threshold bar.
A defense request, filed early in a case, asking the court to throw out all or part of the complaint without trial — for example, because the claim is barred by the statute of limitations or fails to state a legal claim.
A crash involving three or more vehicles, often the result of secondary impacts after the initial collision. Liability among multiple drivers is sorted out using comparative-fault rules.
A settlement provision in which both parties release each other from all claims arising out of the incident. Standard in most personal injury settlements.
↑ Back to A-ZThe failure to use reasonable care that a similarly situated person would use, causing injury to another. The four elements are duty, breach, causation, and damages — all of which the plaintiff must prove.
Example: A driver who runs a stop sign and T-bones another car is acting negligently.
A doctrine under which violating a statute (e.g., a speed-limit law, a building code) is treated as automatic proof of breach of duty, when the statute was designed to prevent the type of harm that occurred.
Example: Running a red light in violation of a state vehicle code is often negligence per se in a collision with cross-traffic.
A theory holding a person liable for giving control of a dangerous instrumentality — most often a vehicle — to someone they knew or should have known was likely to use it dangerously. Common examples include parents entrusting cars to inexperienced or impaired teen drivers, employers letting known-unsafe drivers operate company vehicles, and friends knowingly handing keys to an intoxicated person.
Example: A father who repeatedly lets his teenage son drive the family car despite prior at-fault crashes and a suspended license may face negligent-entrustment exposure if the son seriously injures someone.
A claim for severe emotional distress caused by another's negligence, even without physical injury to the claimant. Recognized in many states with strict limits (e.g., "zone of danger" or "bystander" requirements).
An auto-insurance system in which each driver's own insurer pays for that driver's accident-related medical bills and limited economic losses, regardless of fault. In strict no-fault states, the right to sue for pain and suffering is restricted unless the injury meets a serious-injury threshold.
Jurisdictional Note: Approximately 12 states are no-fault states (e.g., FL, MI, NY). California, Texas, and Washington are at-fault states.
A small symbolic amount (often $1) awarded when a legal wrong is proved but the plaintiff has no measurable financial loss. Rare in personal injury cases.
Damages without a defined dollar value, awarded for pain and suffering, mental anguish, loss of enjoyment of life, disfigurement, and loss of consortium. Some states cap non-economic damages in specific case types (e.g., medical malpractice).
↑ Back to A-ZA common-law rule under which a dog owner is liable only if they knew or should have known the dog had dangerous propensities — historically, by having bitten someone before.
Jurisdictional Note: Texas largely follows the one-bite rule; CA and WA use strict liability statutes that do not require prior notice.
↑ Back to A-ZCompensation for physical pain, discomfort, anxiety, depression, sleep disturbance, and related suffering caused by the injury. It is the most commonly disputed component of non-economic damages.
A physician's numerical estimate (often using the AMA Guides to the Evaluation of Permanent Impairment) of the percentage of permanent loss of function in a body part or the whole person. Used heavily in workers' compensation and as evidence in personal injury cases.
A legal field covering injuries to the body, mind, or emotions (as opposed to property damage). Most personal injury claims arise from negligence — car crashes, slip-and-falls, dog bites, defective products, and medical errors.
First-party auto-insurance coverage that pays for medical bills, lost wages, and sometimes funeral costs after a crash, regardless of fault. Required in no-fault states and optional in some at-fault states.
Jurisdictional Note: PIP is mandatory in many no-fault states. In Washington, PIP must be offered by insurers in writing but can be rejected (RCW 48.22.085).
An unidentified vehicle that causes a crash without physically contacting the claimant's car (for example, by cutting off another driver). Many UM policies cover phantom-vehicle claims if independent corroboration is provided.
The person who files a lawsuit. In personal injury, the plaintiff is the injured person (or, in wrongful death, their personal representative or statutory beneficiaries).
The formal written documents that frame the issues in a lawsuit — typically the complaint (or petition), the answer, and any counterclaims, cross-claims, or third-party claims.
The official report prepared by responding law enforcement after a traffic collision, recording party information, statements, diagram of the scene, citations issued, and the officer's narrative.
The written contract between an insurer and a policyholder. The policy and its declarations page set the coverages, limits, deductibles, exclusions, and conditions that govern any claim.
The maximum amount an insurer will pay under a coverage. Bodily-injury limits are typically per-person and per-accident. Once limits are exhausted, the insured is personally responsible for any remaining liability.
Example: A 100/300 BI policy pays up to $100,000 to any one injured person and up to $300,000 total per accident.
A medical condition that existed before the accident. Insurers often attribute current symptoms to pre-existing conditions, but the eggshell-plaintiff rule generally requires the defendant to compensate for any aggravation caused by the crash.
A resolution reached before a lawsuit is filed, typically based on a demand letter and supporting records. Most personal injury claims actually settle pre-litigation.
A non-recourse cash advance to a plaintiff secured only by an interest in the future settlement. Advances carry high effective rates and reduce the client's net recovery. Several states regulate the practice.
Liability of property owners and occupiers for injuries caused by unreasonably dangerous conditions on the premises. Duties owed depend on whether the visitor is an invitee, licensee, or trespasser.
Example: A grocery store that fails to clean up a spill or warn customers may face premises-liability exposure.
The amount the insured pays — usually monthly, every six months, or annually — to keep an insurance policy in force.
The civil-case burden of proof: the plaintiff's version is "more likely than not" true (greater than 50%). Far lower than the criminal beyond-a-reasonable-doubt standard.
A written notice from a claimant or attorney instructing a potential defendant — or a third party — to preserve specific evidence relevant to a likely lawsuit. Common targets include dash-cam and surveillance video, EDR ("black box") data, cell-phone records, driver logs, maintenance records, and digital communications. Once received, the recipient has a duty to preserve; destruction can produce spoliation sanctions.
Example: After a serious truck-vs-car crash, the plaintiff's lawyer typically sends a preservation letter to the motor carrier within days to ensure dash-cam video, ECM data, and the driver's qualification file are not destroyed in the normal course of business.
Liability of manufacturers, distributors, and sellers for injuries caused by defective products. Theories include manufacturing defect, design defect, and failure to warn.
Compensation for damage to or destruction of personal property — most often a vehicle in auto-accident cases, but also clothing, electronics, child seats, and similar items.
Auto-insurance coverage that pays for damage the policyholder causes to someone else's property (typically their car).
Jurisdictional Note: Minimum PD limits: California $5,000 (rising under SB 1107); Texas $25,000; Washington $10,000.
Damages meant to punish the defendant and deter similar conduct, available only for malicious, fraudulent, oppressive, or grossly reckless behavior.
Example: A drunk driver with multiple prior DUIs may face punitive damages in a serious-injury case.
Jurisdictional Note: Texas caps punitive damages at the greater of $200,000 or 2× economic damages plus an equal amount of non-economic damages up to $750,000. California has no statutory cap but applies constitutional ratio limits.
↑ Back to A-ZA crash in which one vehicle strikes the back of another. The trailing driver is presumed (rebuttably) at fault in most states, on the theory that drivers must maintain a safe following distance.
The legal benchmark used to measure negligence: how a hypothetical careful, prudent person would have acted under the same circumstances. The standard is objective.
Conduct showing a conscious disregard of a known, substantial risk of harm to others — more culpable than negligence but less than intent. Recklessness can support punitive damages in many states.
A verbatim audio (sometimes video) recording in which an insurance adjuster asks a claimant questions about an accident or injury, with the answers locked into the record. Insurers commonly request recorded statements early — often before the claimant has spoken with a lawyer — and can use the statements later to challenge the claimant's testimony.
Example: A claimant who answers "I'm fine" in a recorded statement two days after a crash may have those words quoted back during a deposition months later about chronic neck pain.
Jurisdictional Note: Most policies require cooperation with one's own insurer, which can include providing a recorded statement. There is generally no legal obligation to give a recorded statement to the other side's insurer.
A signed document in which a claimant gives up all current and future legal claims arising out of the accident in exchange for the settlement payment. Once signed, a general release generally cannot be undone.
A discovery tool that asks the other side to admit or deny specific facts under oath. Admissions narrow the issues for trial.
A discovery request asking another party to produce specified documents, electronic data, photographs, videos, or tangible items.
A letter from the insurer to the insured stating that the insurer will defend or investigate a claim while reserving the right to later deny coverage. Reservation-of-rights letters often signal a coverage dispute.
A doctrine holding employers liable for the negligent acts of employees committed within the scope of employment.
Example: If a delivery driver causes a crash while on a delivery, the employer is generally liable along with the driver.
A crash involving a driver for a transportation-network company (TNC) such as Uber or Lyft. Available insurance depends on the driver's app status at the moment of the crash: Period 1 (app on, no ride accepted), Period 2 (ride accepted, en route to pick up), and Period 3 (passenger in the vehicle). In most states the TNC's $1,000,000 liability policy applies in Periods 2 and 3, often with $1,000,000 UM/UIM.
Example: A pedestrian struck by a Lyft driver who has just accepted a ride is generally protected by the TNC's $1,000,000 liability coverage, not just the driver's personal policy.
Jurisdictional Note: Coverage tiers are governed by state TNC statutes — California Public Utilities Code § 5430 et seq., Texas Occupations Code Chapter 2402, and Washington RCW 48.177.
The written contract between an attorney and a client setting out the scope of representation, the fee arrangement (e.g., contingency percentage), how costs are advanced and repaid, and the rights of each side to end the relationship.
The legal entitlement of one road user to proceed before another in a given situation, defined by traffic laws (intersection rules, pedestrian crosswalks, merge lanes). Violating right-of-way rules is a common cause of crashes and a basis for negligence per se.
↑ Back to A-ZA title brand applied to a vehicle that has been declared a total loss by an insurer. Salvage-title vehicles have substantially reduced market value.
The formal delivery of the summons and complaint to the defendant, giving the court personal jurisdiction. Service rules vary by jurisdiction and by defendant type.
A voluntary agreement that resolves a legal claim, usually in exchange for a payment and a signed release. The overwhelming majority of personal injury cases end in settlement, not trial.
A crash in which the sides of two vehicles strike each other, often while changing lanes. Severity depends on closing speed and whether the impact pushes a vehicle out of its lane.
A common type of premises-liability claim involving an injury caused by a slipping hazard — wet floors, ice, freshly polished surfaces, leaks. The plaintiff typically must show the owner knew or should have known of the hazard and failed to fix or warn.
Injury to muscles, tendons, ligaments, fascia, or other non-bony structures — including sprains, strains, contusions, and whiplash. Soft-tissue injuries are common after low-speed crashes and are frequently disputed by insurers.
The intentional or negligent destruction, alteration, or loss of evidence relevant to litigation. Courts can sanction spoliation through monetary penalties, jury instructions adverse to the spoliating party, or — in extreme cases — case-dispositive rulings.
Example: A trucking company that overwrites its dash-cam video after notice of a serious crash may face spoliation sanctions.
A certificate of financial responsibility filed by an auto insurer with the state, proving the driver carries at least the required minimum liability coverage. SR-22s are typically required after a DUI, driving without insurance, or other serious violation.
Combining the uninsured-motorist or underinsured-motorist limits across multiple vehicles or policies to increase available coverage. Whether and how stacking is permitted varies by state and by policy.
Jurisdictional Note: Washington permits stacking under certain conditions; many states (and many policies) prohibit it.
The legal deadline by which a lawsuit must be filed. Missing it almost always bars the claim entirely. Limitations periods vary by claim type and jurisdiction.
Jurisdictional Note: Personal injury: California 2 years (CCP § 335.1); Texas 2 years (Civ. Prac. & Rem. Code § 16.003); Washington 3 years (RCW 4.16.080).
An absolute deadline that bars a claim a fixed number of years after a defined event, regardless of when the injury occurred or was discovered. Most common in product-liability and construction-defect cases.
A written agreement between parties about a procedural or substantive point in a case — for example, agreeing on the authenticity of records or extending a deadline. A stipulation has the force of a court order once approved.
Liability without proof of fault. The plaintiff need only show the defendant caused the harm under circumstances the law has designated "strict" — most commonly dog bites (in some states), defective products, and abnormally dangerous activities.
A settlement paid out over time through an annuity rather than as a single lump sum. Structured settlements are common in catastrophic-injury cases and are required by many courts for minors' settlements.
A court-issued order requiring a witness to appear and testify ("subpoena ad testificandum") or to produce documents ("subpoena duces tecum"). Failure to comply can result in contempt.
An insurer's right to step into the shoes of the insured it has paid and recover those payments from the at-fault party. After paying a collision claim, the insurer typically pursues the other driver's insurer for reimbursement.
A pretrial ruling that there is no genuine dispute of material fact on a claim, allowing the court to decide it as a matter of law without a trial.
The official court notice telling the defendant that a lawsuit has been filed and stating the deadline to respond. Served alongside the complaint.
A claim that survives the death of the injured person, allowing the estate to recover damages the decedent could have recovered if they had lived. Distinct from a wrongful-death claim, which is brought by surviving family members for their own losses.
↑ Back to A-ZA crash in which the front of one vehicle strikes the side of another, typically at an intersection when one driver runs a red light or stop sign. Side-impact crashes have high injury severity because the door provides limited crash protection.
An offer by the at-fault driver's insurer to pay the full policy limit to resolve a claim. A timely policy-limit tender can protect the insurer from later bad-faith exposure.
In an insurance context, someone other than the policyholder. A "third-party claim" is filed against another driver's insurer — for example, the injured person's claim against the at-fault driver's liability carrier.
A legal pause of the statute of limitations clock. Common tolling triggers include the plaintiff's minority, mental incompetency, the defendant's absence from the state, and pending criminal proceedings against the defendant.
Example: If an injured child is hurt at age 10 in a state with a 2-year SOL tolled during minority, the child generally has until two years after their 18th birthday to sue.
A civil wrong — other than a breach of contract — that causes injury and is remedied through damages. Personal injury is one branch of tort law.
The person or entity legally responsible for committing the tort. In a car crash, the at-fault driver is the tortfeasor.
A vehicle that is so badly damaged that repair would cost more than its actual cash value (or the state-defined threshold percentage of ACV). The insurer pays ACV and takes title to the wreck.
Jurisdictional Note: Many states have specific total-loss formula statutes (e.g., California Insurance Code § 11580.011).
An injury that disrupts normal brain function caused by a bump, blow, or jolt to the head or a penetrating head injury. TBI severity ranges from mild (concussion) to severe and can produce long-term cognitive, emotional, and physical effects.
Example: A high-speed rear-end collision can cause a TBI even without direct head trauma because of rapid acceleration-deceleration forces.
A subset of premises-liability claims involving uneven pavement, raised sidewalk slabs, exposed cords, or similar tripping hazards. Many jurisdictions apply a "trivial defect" rule to dismiss claims for very minor elevation changes.
↑ Back to A-ZA stand-alone personal or commercial insurance policy that provides additional liability coverage above the limits of underlying auto, homeowners, or watercraft policies. Personal umbrella policies typically add $1 million or more in coverage and may also cover some risks the underlying policy excludes. They are critical in serious-injury cases where the underlying policy alone is inadequate.
Example: An at-fault driver with a $100,000 auto BI limit and a $2,000,000 personal umbrella has up to $2,100,000 of total liability protection available to an injured plaintiff.
First-party coverage that pays the difference when the at-fault driver has insurance but not enough to cover the injured person's damages, up to the UIM limit. Critical when the at-fault driver carries only state-minimum limits.
Example: If damages are $200,000 and the at-fault driver has a $50,000 BI limit, $100,000 of UIM coverage adds up to $100,000 more in available compensation.
First-party coverage that pays for injuries caused by a driver who has no auto-liability insurance, a hit-and-run driver (in many states), or sometimes a phantom vehicle. Roughly 1 in 7 U.S. drivers is uninsured.
↑ Back to A-ZThe jury's decision in a trial (or the judge's findings in a bench trial). The verdict resolves disputed factual questions and assigns damages where appropriate.
Holding one party legally responsible for the wrongful conduct of another based on a special relationship — for example, employer-employee (respondeat superior), owner-driver, or principal-agent.
Jurisdictional Note: California Vehicle Code § 17150 makes a vehicle owner vicariously liable up to limited statutory amounts for permissive users' negligence.
The jury-selection process. Lawyers and the judge question prospective jurors about background, biases, and exposure to the case, and may strike jurors for cause or by peremptory challenge.
↑ Back to A-ZThe negotiating term for the minimum amount a plaintiff (or the maximum amount a defendant) will accept to resolve the case. Used internally — typically not disclosed across the table.
A bony or soft-tissue neck injury caused by sudden acceleration-deceleration forces — most often in rear-end collisions. Symptoms can include neck pain and stiffness, headache, dizziness, arm pain, numbness, memory or concentration problems, and psychological distress. Many cases resolve in weeks; others become chronic.
A claim brought by statutorily designated survivors (such as a spouse, children, or parents) for their own losses arising from a person's death caused by another's negligent or wrongful act. Recoverable damages typically include loss of financial support, loss of companionship, and funeral costs.
Jurisdictional Note: California: CCP § 377.60 et seq. Texas: Civ. Prac. & Rem. Code § 71.001 et seq. Washington: RCW 4.20.010 et seq.
