Personal Injury Statute of Limitations: How Long You Have to File

The deadline to file a personal injury lawsuit — called the statute of limitations — is set by state law and typically falls somewhere between one and six years from the date you were hurt, with two to three years being the most common range. There is no single national deadline. The exact number of years, and important exceptions to it, depend entirely on your state and the type of claim, so the most important step is confirming the specific deadline that applies to your case rather than assuming a general rule applies to you.

Missing this deadline is usually fatal to a claim. Once the statute of limitations expires, the court can dismiss your case no matter how strong the evidence is or how badly you were injured. That makes this one of the few truly hard deadlines in a personal injury case — there is rarely a way to "make up for" filing late.

Why the deadline varies so much

Personal injury law in the United States is mostly state common law, not federal law. Each state legislature sets its own statute of limitations for different kinds of claims — for example, a car accident, a slip-and-fall, a medical malpractice claim, and a product liability claim can each have a different deadline within the same state. Some states also apply different rules depending on whether the defendant is a private individual, a company, or a government entity. Because of this patchwork, it is not safe to rely on something you read online, heard from a friend, or remember from a different state — you need to confirm the rule that applies to your situation, your state, and your type of claim.

The "discovery rule": when does the clock actually start?

In most cases, the clock starts on the date you were injured. But many states recognize a discovery rule for certain types of harm — meaning the clock instead starts when you discovered, or reasonably should have discovered, that you were injured and that the injury was caused by someone else's conduct. This matters most in cases where harm isn't obvious right away, such as:

• Medical malpractice (a surgical error or misdiagnosis that isn't discovered until months or years later)
• Exposure to a toxic substance or defective drug/device with delayed symptoms
• Some product liability and construction defect cases

Whether the discovery rule applies, and how it's calculated, varies by state and by claim type. Some states also have a separate outer limit called a statute of repose, which can cut off a claim after a set number of years regardless of when the injury was discovered. If your injury wasn't obvious immediately, this is an area where getting a professional read on your specific timeline is especially important.

Special situations that pause or shorten the clock

Minors (children under 18)

Most states "toll" (pause) the statute of limitations for injury claims involving a child until the child turns 18. Once they reach adulthood, the standard filing window typically begins running from that point, though the exact mechanics differ by state, and some states place their own outer limits on how long the pause can last. Parents shouldn't assume they have unlimited time simply because their child is a minor — some claims tied to the incident (such as a parent's own claim for medical expenses) may run on a separate, shorter clock even while the child's claim is tolled.

Claims against a government agency

This is the single biggest trap people fall into. If your injury involved a city bus, a pothole on a public road, a government building, a public school, a county vehicle, or any other government entity, ordinary statute-of-limitations timelines usually do not apply. Instead, most states require you to file a formal "notice of claim" with the government agency within a very short window — commonly measured in weeks to a few months, not years — before you're allowed to sue at all. Miss that notice deadline and you may lose your right to any recovery, even if the regular statute of limitations hasn't expired yet.

The same principle applies at the federal level. Under the Federal Tort Claims Act (28 U.S.C. § 2401(b)), a person injured by the negligence of a federal employee acting within the scope of employment generally must first present an administrative claim to the relevant federal agency within two years of the injury, and then, if the claim is denied, file suit in federal court within six months of the denial. That is a materially different — and shorter — process than a typical injury lawsuit against a private individual or business.

If a government entity of any kind was involved in how you were hurt, treat that as time-sensitive and look into the notice requirement immediately — do not wait until you'd normally expect to deal with a lawsuit deadline.

What to do if you've been injured

1. Write down the date of the injury and mark your calendar early. Don't rely on memory months later.
2. Identify who may be responsible — a private individual, a business, or any government agency (even partially). This single fact can change your deadline dramatically.
3. Get medical care and keep records. Medical documentation ties your injury to a date and supports both the discovery-rule timeline and the value of your claim.
4. Don't wait for insurance negotiations to resolve before checking the legal deadline. Settlement talks with an insurance company do not automatically pause or extend your statute of limitations in most states.
5. Confirm your state's specific deadline for your type of claim — through your state courts' self-help resources, your state bar's lawyer referral service, or a consultation with a personal injury attorney. Initial consultations are commonly free.
6. If a government entity may be involved, ask specifically about notice-of-claim deadlines right away, since these are often far shorter than the general filing deadline.
7. If you're close to any deadline, file or retain counsel immediately rather than continuing to negotiate informally.

How personal injury claims generally work (background)

Most personal injury claims are built around a negligence framework: the injured person (plaintiff) generally must show the other party owed a duty of care, breached that duty, and that the breach caused damages. Most states also apply some form of comparative fault — reducing (rather than eliminating) your recovery if you were partly at fault — while a small number of states still follow stricter contributory negligence rules that can bar recovery if you were even minimally at fault. Which rule applies is state-specific and worth confirming with a local attorney if fault is contested.

Most personal injury cases settle before trial, and most injury attorneys handle these cases on a contingency fee basis — commonly around one-third of any recovery — meaning you typically pay nothing upfront and the fee comes out of a settlement or verdict, not out of pocket.

Key takeaways on timing

• Statute of limitations ranges are typically one to six years depending on the state and claim type — there is no universal number.
• The discovery rule can delay the start of the clock in cases where harm wasn't immediately obvious, such as some medical or exposure-related injuries.
• Claims involving a child are usually tolled until age 18, but the details vary by state.
• Claims against a government entity almost always carry a much shorter separate notice deadline — often weeks to a few months — that can end your case before the general deadline would even apply.
• When in doubt, treat the deadline as closer than you think and confirm it with your state courts or a licensed attorney promptly.
