Personal Injury Terminology

Understanding the language of personal injury law can feel overwhelming. Whether you’re dealing with an accident claim or simply trying to make sense of a lawsuit you’re involved in, having a reliable glossary of terms can make a real difference. Below, Missouri Injury Law Firm offers a detailed list of key terms used in personal injury cases—explained in plain English. This isn’t meant to replace legal advice, but it might just help you feel a bit less lost in the legal maze.

A–C: From Accident Reports to Compensation

Accident Report

A written account of an incident, usually completed by a police officer or official. It often includes basic facts like date, time, location, parties involved, and witness statements. Insurance companies and lawyers frequently refer to this document to support or dispute claims.

Adjuster

An employee of the insurance company who investigates the claim. They’ll often assess medical records, accident reports, and any other evidence before proposing a settlement. Not always on your side, though—it’s their job to protect the insurer’s interests.

Assumption of Risk

A legal defence where the defendant argues that the injured party knowingly took on the risks involved. Think of someone getting hurt while skydiving, for instance—it can make compensation trickier.

Burden of Proof

In civil cases, the plaintiff carries this. They must show that the defendant’s actions more likely than not caused the injuries. Not beyond all doubt, but more than 50% certainty.

Causation

There must be a direct link between the defendant’s actions and the injury. If someone slips on a spill that had been left unattended, causation would connect the lack of cleanup to the resulting injury.

Claim

The formal request for compensation made by the injured party—often filed with an insurance company or in court.

Compensation

This refers to the money awarded to someone who’s been injured or suffered losses. It might cover medical expenses, pain and suffering, lost income, or property damage. Rarely does it “fix” everything, but it helps ease the fallout.

D–F: From Damages to Fault

Damages

These are the losses the injured person suffers—economic (like hospital bills or missed workdays) and non-economic (like emotional distress or loss of companionship). It’s the legal system’s attempt to quantify harm. Learn more. 

Defendant

The person, business, or entity being accused of causing the injury. In some cases, there can be more than one.

Deposition

An out-of-court statement, usually under oath. Lawyers ask questions, and the witness answers. These are recorded and can be used later in court.

Duty of Care

The legal obligation one has to avoid causing harm to others. Drivers, for example, owe a duty of care to everyone else on the road.

Expert Witness

A specialist—often a doctor or accident reconstructionist—who helps clarify complex issues for the court. Their testimony can seriously influence the case.

Fault

Used to determine who is responsible for the injury. Missouri follows a comparative fault system, meaning even if the injured person shares some blame, they might still recover part of their damages. Learn more.

G–L: From Gross Negligence to Liability

Gross Negligence

Beyond a simple mistake—this is reckless or willful disregard for someone’s safety. Courts often frown on this, and it can lead to punitive damages.

Independent Medical Examination (IME)

Sometimes requested by the defendant’s insurance. You see a doctor they choose, who then gives their opinion on your injuries. Not always as “independent” as the name suggests.

Injunction

A court order that tells someone to do—or not do—something. Rare in personal injury but might apply in cases involving ongoing harm.

Injuries

This includes physical, emotional, or psychological harm caused by an accident. Broken bones, PTSD, chronic pain—they all fall under this umbrella.

Insurance Claim

A formal demand made to an insurance company after an accident. This is often the first step in seeking compensation.

Liability

Who is legally responsible? Proving liability is central to any personal injury case. It often involves showing negligence or breach of duty. Learn more.

M–P: From Medical Expenses to Plaintiff

Medical Expenses

The costs tied to treating an injury. This can include hospital visits, surgery, rehabilitation, medications, and even future care. Often the largest component of a compensation claim.

Negligence

One of the most common legal bases for personal injury. It means someone failed to take reasonable care, and that failure led to someone else’s harm. Not always clear-cut, but central to most claims. Learn more.

Pain and Suffering

A form of non-economic damages. It’s tough to measure, but courts recognise that injuries affect more than just the body. The emotional toll, loss of enjoyment in life, or chronic discomfort—all fall under this category.

Permanent Disability

An injury that permanently affects your ability to work or live as you once did. These cases often lead to higher compensation amounts due to lifelong impacts.

Plaintiff

The injured person who brings the lawsuit against the defendant. In most cases, they’re the ones trying to prove liability and secure damages.

Q–S: From Settlement to Statute of Limitations

Settlement

A resolution between parties before a case goes to trial. Most personal injury cases settle out of court, often through negotiation or mediation. It can be faster and less emotionally draining, but sometimes the offers fall short of what’s fair. 

Statute of Limitations

A legal deadline. In Missouri, most personal injury claims must be filed within five years of the incident. Miss it, and your right to seek compensation could vanish entirely.

Strict Liability

Applies when responsibility doesn’t require proof of negligence. For example, in defective product claims, a manufacturer might be held strictly liable even if they didn’t act carelessly.

Subrogation

When your insurer pays your expenses but later goes after the party at fault to get their money back. You might not even hear about it happening, but it’s common behind the scenes.

T–Z: From Trial to Witness Testimony

Trial

If no settlement is reached, the case may go to trial. This is where evidence is presented, witnesses testify, and a judge or jury makes the final decision.

Verdict

The final decision in a trial. It can include a determination of liability and the amount of damages awarded.

Witness Testimony

Statements given by individuals—either eyewitnesses or experts—to help establish facts in the case. This can make or break a claim, especially when physical evidence is limited.

Wrongful Death

A legal action brought when someone dies due to another’s negligence or misconduct. The claim is typically filed by close relatives and seeks compensation for loss of support, funeral costs, and emotional pain.
