A personal injury claim is a request for money from the person or business whose carelessness caused your injury, usually paid through their insurance. To win, you generally have to show that the other side owed you a duty of reasonable care, failed to meet it, and caused harm that can be measured. The details that decide most cases, including how shared fault is handled and how long you have to file, are set by each state, so the same accident can lead to different outcomes depending on where it happened.
Key points
- Most injury claims rest on negligence: a duty of care, a breach of that duty, causation and real damages.
- Compensation can cover medical bills, lost income, future care and pain and suffering. Punitive damages are rare and reserved for extreme conduct.
- Every state has a filing deadline (the statute of limitations). It ranges from one year to six depending on the state, and claims against government bodies often have much shorter notice rules.
- If you were partly at fault, most states reduce your award by your percentage of fault rather than barring it, but the cutoffs vary.
- Photographs, medical records, witness names and the other party's insurance details are easiest to collect in the first days after an injury.
What counts as a personal injury claim
Personal injury is a broad label for civil claims over harm to your body or mind, as opposed to a criminal prosecution, which the state brings to punish an offender. The most common claims come from car and motorcycle crashes, but the same rules govern a wide range of situations:
- Crashes with commercial vehicles, covered in our guide to truck accident lawsuits
- Crashes caused by impaired drivers, explained in our drunk driving accident guide
- Falls and injuries on job sites, where construction accident claims often run alongside workers' compensation
- Injuries during childbirth and other medical errors, such as birth injury claims
- Neglect or abuse of an older relative in care, covered in our nursing home abuse guide
- Unsafe property conditions, from broken stairs to unfenced pools, including drowning and pool accidents
When an injury is fatal, the claim usually becomes a wrongful death lawsuit, brought by family members or the estate under a separate set of state rules.
Proving negligence
Negligence is the legal theory behind most injury cases. It does not require proof that anyone meant to hurt you. It asks whether the other person acted the way a reasonably careful person would have acted in the same situation.
Duty and breach
Drivers owe a duty to drive with reasonable care. Store owners owe customers a duty to fix or warn about hazards they know about or should have found. Doctors owe patients care that meets the accepted standard in their field. A breach is the gap between what the person should have done and what they did: running a red light, leaving a spill on the floor for hours, missing a warning sign on a fetal heart monitor.
Some breaches are easier to prove because the conduct also broke a safety law. In many states, violating a statute meant to protect people like you (a traffic law, a building code, a federal trucking rule) can establish or strongly support the breach element. The term for this is negligence per se, and how it works differs by state.
Causation and damages
You also have to connect the breach to your injury. Insurers often argue that the harm came from a preexisting condition, a later event or the injured person's own choices. Medical records that document symptoms from the first visit onward are the usual answer to that argument. Finally, there must be actual damages. A near miss with no injury, however frightening, does not usually support a claim.
Other theories of liability
Not every injury case is about negligence. Manufacturers of defective products can be held strictly liable in most states, meaning you do not have to prove carelessness, only that the product was defective and caused the harm. Intentional wrongs such as assault are also civil claims, and when a crime happened on someone's property, the owner may face a negligent security claim, which our crime victims guide explains. Employers are generally responsible for the negligence of employees acting within the scope of their jobs, which is why a delivery company, not just its driver, is often the defendant after a crash.
What compensation can cover
Damages are the money a court awards, or an insurer agrees to pay, to make up for an injury. They fall into three groups.
Economic damages
These are the losses you can document with bills and pay stubs: emergency care, surgery, therapy, medication, medical equipment and home modifications. Lost wages count, and so does lost earning capacity when an injury prevents a return to the same work. For serious injuries, a life care plan prepared by medical and economic experts estimates future costs over decades.
Noneconomic damages
Pain, emotional distress, loss of enjoyment of life and disfigurement have no receipts, but they are often the largest part of an award for a serious injury. A spouse may also have a claim for loss of consortium, meaning the loss of companionship and support. Some states cap noneconomic damages, especially in medical malpractice cases, and the caps and their exceptions vary widely.
Punitive damages
Punitive damages punish conduct that goes beyond carelessness, such as a deliberate safety violation or driving while heavily intoxicated. Many states require clear and convincing evidence and limit the amount, and some do not allow punitive damages in certain kinds of cases at all. Insurance policies may not cover them, which affects whether they can actually be collected.
How shared fault changes recovery
Defendants often argue that the injured person was partly to blame: looking at a phone while crossing, not wearing a seat belt, ignoring a warning sign. How much that matters depends on the state's fault rule.
| Rule | How it works | Examples |
|---|---|---|
| Pure contributory negligence | Any fault on your part can bar recovery entirely, subject to narrow exceptions | Alabama, Maryland, North Carolina, Virginia and the District of Columbia (DC has carved out some pedestrian and cyclist crashes) |
| Pure comparative fault | Your award is reduced by your share of fault, even if you were mostly to blame | California, New York |
| Modified comparative fault | Your award is reduced by your share of fault, but you recover nothing once your share reaches the state's threshold (50 or 51 percent) | Florida since March 2023 for most negligence claims; Louisiana for incidents on or after January 1, 2026 |
The recent changes in Florida and Louisiana show how quickly this area moves. Florida's 2023 tort reform law moved most negligence claims from pure to modified comparative fault, though medical negligence claims kept the pure rule. Louisiana's legislature replaced pure comparative fault in 2025, with the new rule applying to incidents from January 1, 2026. If your injury happened near one of these change dates, the older rule may still apply to you.
Filing deadlines vary by state
The statute of limitations is the deadline to file a lawsuit. Miss it and the claim is usually gone, no matter how strong it was. Most states set two or three years for general personal injury claims, but the range is wider than many people expect. Tennessee's general deadline is one year from the injury, with limited exceptions. Maine allows six years for most civil actions.
These periods change too. Florida cut its general negligence deadline from four years to two for claims arising after March 24, 2023. Louisiana went the other way, extending its one-year deadline for most injury claims to two years for injuries after July 1, 2024.
Several rules can change the start date or pause the clock:
- In some cases, such as a surgical error found years later, the clock may start when the injury was discovered or reasonably should have been.
- Many states pause the deadline until a child turns 18, but medical malpractice claims often have shorter, special rules for children.
- Claims against cities, counties, school districts or state agencies usually require a formal notice of claim, sometimes within a few months of the injury. Claims against federal agencies go through the Federal Tort Claims Act, which requires a written administrative claim within two years (28 U.S.C. § 2401(b)).
- Some claims, particularly product and medical cases, are subject to a statute of repose, an outer limit that applies no matter when the injury was discovered.
Because these rules interact, the safest course is to have a lawyer licensed in the state where the injury happened confirm your deadline early. Laws change, and a deadline in an older article may no longer be accurate.
Insurance and how claims get paid
In practice, most injury compensation comes from insurance, not the at-fault person's own pocket. Auto liability policies, homeowner and renter policies, business general liability policies and professional malpractice coverage are the usual sources. Policy limits often cap what can realistically be collected, which is why identifying every policy and every potentially responsible party matters early.
Your own coverage can also pay. Uninsured and underinsured motorist coverage applies when the at-fault driver has no insurance or too little. Health insurance pays medical bills in the meantime, but it may later seek reimbursement from a settlement, a right called subrogation. A minority of states use no-fault auto insurance systems, which require you to claim first against your own personal injury protection coverage and limit lawsuits to more serious injuries. The thresholds differ by state.
When you report a claim, the other side's adjuster may ask for a recorded statement or a broad medical authorization. You are not usually required to provide either to someone else's insurer, and it is reasonable to speak with a lawyer first.
How a claim moves from injury to resolution
Most claims follow a similar path, although timing varies with the severity of the injury.
- Getting care promptly protects your health and creates the record that links the injury to the event.
- Police reports, photographs, video, witness statements and, in vehicle cases, electronic data from the vehicles are gathered.
- Lawyers often wait until doctors can say what the long-term picture looks like, so future costs are not underestimated.
- A demand package with records, bills and a damages summary goes to the insurer, followed by offers and counteroffers.
- If the claim does not settle, filing a lawsuit starts discovery: written questions, document exchange and depositions. Many cases settle during this stage or at mediation.
- A small share of cases are decided by a judge or jury.
A settlement usually ends the claim permanently, so it should account for future medical needs, liens from health insurers or public programs, and taxes where relevant. For a walk through the filing process in one state, see this explainer on how a personal injury lawsuit is filed.
Evidence worth preserving
Evidence fades quickly. Surveillance video is often recorded over within days or weeks, and vehicles are repaired or scrapped. Useful steps include photographing the scene and your injuries over time, keeping damaged clothing or equipment, writing down what happened while it is fresh, saving texts and emails about the incident, and keeping a simple record of missed work and daily limitations. When an important item is in the other side's hands, a lawyer can send a preservation letter demanding that it be kept, which matters a great deal in cases involving commercial vehicles or a business's video system.
Social media posts are routinely reviewed by insurers. A photo from a family event can be presented as proof that an injury is minor, even when the reality is different.
