Legal Glossary

A scientific method of analyzing physical evidence, vehicle damage, road conditions, and other data to determine how an accident occurred, the speeds involved, and who was at fault.

The determination of whether evidence may be presented in court. Evidence must meet rules of relevance, reliability, and other legal standards to be admitted. Inadmissible evidence cannot be considered by the jury.

A defense raised by the defendant that, if proven, defeats the plaintiff's claim even if the plaintiff proves all elements of their case. Examples include assumption of risk, comparative negligence, and statute of limitations.

Methods of resolving legal disputes outside of traditional court proceedings, including mediation, arbitration, and negotiation. ADR is often faster and less expensive than trial.

The surgical removal or traumatic loss of a limb or extremity. Amputations resulting from accidents are considered catastrophic injuries and often involve extensive medical care, prosthetics, and long-term rehabilitation.

A financial product that pays out a fixed stream of payments over time. In personal injury, annuities are used to fund structured settlements, providing periodic payments instead of a lump sum.

The defendant's formal written response to the plaintiff's complaint, admitting or denying each allegation and raising any defenses or counterclaims.

A request to a higher court to review and reverse a lower court's decision. Appeals focus on errors of law rather than reexamining facts.

A form of alternative dispute resolution where a neutral arbitrator hears both sides and issues a binding or non-binding decision. Many contracts include mandatory arbitration clauses.

A naturally occurring mineral fiber once widely used in construction and manufacturing that causes mesothelioma, lung cancer, and asbestosis when inhaled. Asbestos litigation is one of the largest mass tort categories in U.S. history.

The intentional act of creating a reasonable apprehension of imminent harmful or offensive contact. In tort law, assault does not require actual physical contact.

A failure to meet the required standard of care. In a personal injury case, the plaintiff must prove that the defendant breached their duty of care through action or inaction.

The obligation of a party to prove their claims. In personal injury cases, the plaintiff bears the burden of proving liability and damages by a 'preponderance of the evidence' — meaning more likely than not.

Damage to the skin and underlying tissue caused by heat, chemicals, electricity, or radiation. Burns are classified by degree: first-degree (superficial), second-degree (partial thickness), and third-degree (full thickness).

A test for causation that asks: 'But for the defendant's action, would the plaintiff have been injured?' If the injury would not have occurred without the defendant's conduct, causation is established.

A severe injury that permanently prevents the victim from performing gainful work or living independently. Examples include traumatic brain injuries, spinal cord injuries, amputations, and severe burns.

The requirement that the defendant's breach of duty directly caused the plaintiff's injuries. Causation has two components: cause-in-fact (but-for causation) and proximate cause (legal causation).

The legal basis or grounds on which a plaintiff brings a lawsuit. Common causes of action in personal injury include negligence, strict liability, and intentional torts.

The documented trail showing the seizure, custody, control, transfer, and disposition of physical evidence. Maintaining the chain of custody ensures evidence has not been tampered with and is admissible in court.

A request to move a trial from one court location to another, often due to concerns about local bias, pretrial publicity, or the convenience of parties and witnesses.

Permanent changes to a person's physical appearance resulting from an injury, such as scarring, loss of a limb, or facial damage. Disfigurement is compensable as a non-economic damage.

Operating a vehicle while engaged in activities that divert attention from driving, such as texting, eating, or using GPS. Distracted driving is a leading cause of accidents nationwide.

Laws governing an animal owner's responsibility for injuries caused by their pet. Some states follow strict liability (owner is liable regardless of prior knowledge), while others follow the 'one bite rule.'

Laws that hold bars, restaurants, and liquor stores liable for injuries caused by intoxicated patrons they served. Many states have dram shop statutes that allow injured parties to sue the establishment that over-served the drunk driver.

Driving Under the Influence — operating a vehicle while impaired by alcohol or drugs. DUI drivers who cause accidents may face both criminal charges and civil liability for injuries. Punitive damages are often available.

An implied obligation to deal honestly and fairly. In insurance law, insurers have a duty to handle claims in good faith. Failure to do so may give rise to a bad faith claim.

A claim filed against a government entity for injuries caused by its employees or dangerous conditions on government property. Special rules and shorter deadlines often apply.

A conscious, voluntary disregard of the need to use reasonable care, which is likely to cause foreseeable grave injury or harm. Gross negligence is more severe than ordinary negligence and may support punitive damages.

A person appointed by the court to represent the best interests of a minor or incapacitated person in legal proceedings. In personal injury cases involving children, a guardian ad litem may be required to approve settlements.

An accident where two vehicles traveling in opposite directions collide front-to-front. Head-on collisions are among the most deadly types of crashes due to the combined impact forces.

An accident where the at-fault driver flees the scene without stopping to exchange information or render aid. Hit-and-run is a criminal offense, and victims may recover through their own uninsured motorist coverage.

An obligation to compensate another party for losses or damages. In personal injury, indemnification agreements may require one party to cover another's liability.

A medical evaluation performed by a doctor chosen by the insurance company or defendant, not the plaintiff's treating physician. Despite the name, IMEs are often biased in favor of the party requesting them.

The legal requirement that healthcare providers fully explain the risks, benefits, and alternatives of a proposed treatment before a patient agrees to it. Failure to obtain informed consent can be the basis of a medical malpractice claim.

An employee or contractor of an insurance company who investigates claims, evaluates damages, and recommends settlement amounts. Adjusters work for the insurance company, not the injured party.

A legal action involving numerous plaintiffs with similar claims against one or a few defendants, such as defective drug or medical device cases. Unlike class actions, each plaintiff's case is evaluated individually.

The point at which a patient's condition has stabilized and is not expected to improve further with additional treatment. MMI is a critical milestone in personal injury cases, as it allows for accurate assessment of permanent impairment and future medical needs.

A voluntary dispute resolution process where a neutral third party (mediator) helps the parties reach a mutually acceptable settlement. Unlike arbitration, the mediator does not make a binding decision.

The costs of medical treatment related to the injury, including emergency room visits, surgeries, hospital stays, physical therapy, medication, and future anticipated medical care.

A claim against a healthcare provider who deviates from the accepted standard of care, causing injury to a patient. Medical malpractice cases require expert medical testimony and are subject to special procedural rules in most states.

Optional auto insurance coverage (MedPay) that pays for medical expenses for the policyholder and passengers, regardless of fault. Unlike PIP, MedPay does not cover lost wages.

Documentation of a patient's medical history, diagnoses, treatments, and outcomes. Medical records are the most important evidence in personal injury cases, proving the nature and extent of injuries.

The lowest amount of liability insurance required by state law. Minimum coverage requirements vary significantly by state and are often inadequate to fully compensate seriously injured victims.

A request by the defendant to have the case thrown out before trial, arguing that even if all the plaintiff's allegations are true, they do not constitute a valid legal claim.

A chain-reaction collision involving three or more vehicles. Pileups create complex liability scenarios where multiple drivers may share fault, making investigation and insurance claims more challenging.

A federal legal procedure that transfers multiple lawsuits with common issues of fact to a single court for coordinated pre-trial proceedings, improving efficiency while preserving individual claims.

A common method for calculating pain and suffering damages by multiplying the total economic damages by a factor (typically 1.5 to 5) based on the severity of the injury.

The failure to exercise the level of care that a reasonably prudent person would in similar circumstances. Negligence is the most common basis for personal injury claims and requires proving duty, breach, causation, and damages.

A lasting physical or mental limitation resulting from an injury that persists after the patient reaches maximum medical improvement. The degree of permanent impairment is typically rated by a physician and significantly affects case value.

A legal term for an injury to the body, mind, or emotions — as opposed to damage to property. Personal injury claims allow injured parties to seek compensation from the party whose negligence or intentional act caused the harm.

A type of no-fault auto insurance coverage that pays for the policyholder's medical expenses and lost wages regardless of who caused the accident. PIP is mandatory in no-fault states.

The person who initiates a lawsuit by filing a complaint. In personal injury cases, the plaintiff is typically the injured party seeking compensation from the defendant.

Additional damages awarded to punish the defendant for particularly egregious, willful, or malicious conduct and to deter similar behavior. Not available in all cases or all states, and often subject to statutory caps.

An accident where one vehicle strikes the back of the vehicle in front of it. In most cases, the rear driver is presumed at fault for following too closely, though exceptions exist.

A manufacturer's action to remove or correct a product found to be defective or dangerous. Federal agencies like the NHTSA (vehicles) and CPSC (consumer products) can order mandatory recalls.
