Personal injury claims: proof, losses and deadlines

California’s official court self-help guide describes the basic situation plainly: if you are hurt because of someone else’s actions, you may decide to sue them, and the injury can be physical, emotional or psychological (California Courts: personal injury cases). Common examples on that page are car crashes, slips and falls, workplace injuries, and assault or other intentional harm. Workplace injuries may involve a workers’ compensation claim instead of, or as well as, a lawsuit.

The legal reason for the claim

A lawsuit needs a cause of action, the legal reason you can sue. The California guide gives two common ones: negligence, where someone acted carelessly and caused injury, and battery, where someone hurt you intentionally. It also stresses that you must prove every part of the cause of action you choose.

For negligence, those parts are typically a duty of care, a breach of that duty, harm, and causation, according to the educational summary in Cornell’s Wex encyclopedia (Wex: negligence). The broader map of tort categories is in our tort law guide.

Proving your losses

Damages are the money you ask for. The California guide suggests listing every loss the injury caused: medical bills, lost wages, ongoing treatment, emotional harm, and future problems from the injury. It adds a practical warning: some damages are easy to prove with bills, while others, such as emotional distress, are harder to value. The court guide offers no formula for what a claim is worth, and neither does this one.

Deadlines are set state by state

There is no single nationwide deadline for personal injury claims. Each jurisdiction sets its own statute of limitations, and the rules can change with the kind of claim and the kind of defendant.

As one example, California’s court guidance says you usually have two years from the date of the injury to sue, and that the deadline is shorter if you want to sue a government agency. That is a California rule, not a national one; check the law of the state where you would file.

Who and where to sue

The California guide says people often sue the person who caused the injury, the owner of the car or property, or an employer if the person was working at the time. In California you usually file in the county where the injury happened or where the defendant lives or does business. Other states have their own venue rules.

An insurance claim is not a lawsuit

An insurance claim and a court case are different processes. The California guide suggests that if you have insurance, you talk to your insurance company: it may pay some costs so you do not have to sue, or you may sue only for what insurance does not cover. If someone accuses you of causing an injury, it advises checking whether your insurance covers it, because your insurance contract may require you to report it.

Your own insurer and another person’s insurer are different relationships. Your own policy is a contract you can read. The other driver’s or property owner’s insurer is not your insurer, and a lawsuit, if one is filed, usually names the person or business responsible. Texas’s insurance regulator, for example, publishes separate guidance on dealing with the other driver’s insurer (Texas Department of Insurance). For disputes with your own insurer, see our insurance disputes guide.

Evidence to keep

The California guide lists photos of the scene or injuries, medical bills or doctor reports, witness statements, and police reports. In federal court, discovery can require each side to share witness identities and related documents, and the plaintiff must prove the case by a “preponderance of the evidence,” meaning more likely than not (U.S. Courts: civil cases). Keep originals, and read our guide to preserving evidence in a dispute before deleting anything.

A short checklist

• Collect the proof of loss. Medical bills, doctor reports, pay records and repair estimates.
• Keep photos, police reports and messages. Do not edit or delete them.
• Read your own insurance policy. Note any reporting requirement and what it covers.
• Find the deadline for your state. Check for shorter rules for government defendants.
• Consider a lawyer for serious cases. The California guide flags severe or long-term injuries, large damages, unclear fault, or several possible defendants.
