Of all the numbers in an injury claim, one carries more finality than any other: the deadline to file a lawsuit. Miss it and the strongest, best-documented case in the world is usually worth nothing. This guide explains what a statute of limitations is, when the clock starts, the exceptions that can extend it, and the much shorter deadlines that apply when the defendant is a government agency.
A statute of limitations is a law that sets the maximum time after an injury within which you can start a lawsuit. The period for personal injury is set by each state's civil practice statutes — for example, a state's code of civil procedure or its general statutes on limitation of actions. When that window closes, the defendant can ask the court to dismiss the case, and courts routinely grant that request regardless of how serious the injury was or how clear the other side's fault is.
The reason these deadlines exist matters for understanding why courts enforce them so strictly: evidence degrades, memories fade, and witnesses move or pass away. The law treats the limitation period as a fairness rule for both sides, which is exactly why "I didn't know" is rarely a valid excuse once the clock has run.
As a general rule, the limitations clock starts on the date the injury occurs — the day of the car crash, the slip and fall, or the collision. From that date, the state's period (often two or three years) counts down. If your state's limit is two years and you were hurt on June 1, your lawsuit generally must be filed on or before June 1 two years later.
States fall into rough buckets for the standard personal-injury limitation period. The table below shows illustrative examples only. It is a snapshot to show the range, not a lookup chart to rely on.
| Bucket | Illustrative period | Example states often cited |
|---|---|---|
| Shorter | ~1 year | Louisiana, Tennessee, Kentucky |
| Common | ~2 years | California, Texas, Illinois |
| Common | ~3 years | New York, Massachusetts, Washington |
| Longer | ~4+ years | Florida (certain claims), Nebraska, Wyoming |
Some injuries are not apparent on the day they happen. A surgical sponge left in the body, exposure to a toxic substance, or a defective implant may cause harm that surfaces months or years later. Many states apply a "discovery rule" in these cases, which starts the clock not on the date of the wrongful act but on the date you discovered, or reasonably should have discovered, the injury and its likely cause.
The discovery rule is narrower than it sounds. Courts ask what a reasonable person would have noticed, and many states cap how long the rule can extend the deadline with an outer limit called a statute of repose. Because the rule's scope is heavily fact-dependent, it is one of the most important questions to put to an attorney rather than judging on your own.
"Tolling" means pausing the clock. Two common grounds:
Tolling is an exception, not a default. Do not assume it applies; confirm it.
When the defendant is a city, county, state, or federal agency, ordinary limitation periods often do not control. Government entities are protected by sovereign immunity, waived only on the conditions set out in a tort-claims act. These acts typically impose a short notice-of-claim deadline — often six months to a year — that requires you to file a formal written notice with the correct agency before you can ever sue.
Miss the notice deadline and you can lose the right to sue even though the longer lawsuit deadline has not yet passed. Public transit agencies frequently have their own notice requirements and abbreviated timelines on top of this. Federal claims follow the Federal Tort Claims Act, which has its own administrative-claim process and deadlines. The authoritative source here is the relevant entity's specific tort-claims act and its claim-filing rules, which an attorney experienced in government claims should review immediately.
Wrongful-death claims have their own limitation period, which many states measure from the date of death rather than the date of the underlying injury. When a person is injured and later dies, the date that starts the clock can shift, and survival actions (brought on behalf of the estate) may follow yet another rule. Families should treat these deadlines as separate from a standard injury claim and confirm them promptly.
People often confuse two unrelated timelines. The statute of limitations is the deadline to file a lawsuit in court. Your insurance policy also contains contractual deadlines — for prompt notice of a claim, for submitting proof of loss, and sometimes for demanding uninsured-motorist arbitration. Those insurer deadlines are usually much sooner, sometimes within days of the incident. Meeting an insurer's notice requirement does nothing to preserve your right to sue, and vice versa. Both clocks run independently.
To stop the statute of limitations, you must file an actual lawsuit — a complaint or petition submitted to the proper court — before the deadline. Sending a demand letter to the insurer, opening a claim, or negotiating an offer does not stop the clock. Settlement talks can drag on while the deadline quietly approaches; if the period expires mid-negotiation, your leverage evaporates because the insurer knows you can no longer sue.
Even when a deadline is years away, treating it as a comfortable cushion is a mistake. A solid case takes months to build: gathering medical records, obtaining the police or incident report, identifying all liable parties and insurers, consulting experts, and reaching maximum medical improvement so damages can be valued. Attorneys also need lead time to evaluate and accept a case — many decline to take on a claim that arrives with only weeks left before the deadline because there is no time to investigate properly. Acting early protects evidence and preserves room to negotiate.
For a YMYL legal question like this, do not rely on a general number. The authoritative sources are: your state's civil practice statutes (the actual limitation-of-actions law), your state bar association (most publish public guidance and lawyer-referral services), and, for claims against a public entity, that entity's governing tort-claims act and notice rules. Above all, confirm the exact deadline with an attorney licensed in your state as early as possible.
Rarely. A handful of exceptions (such as the discovery rule or tolling for minors or incapacity) can extend the original window, but they must apply at the time, not be invoked after the fact. Once a properly running period expires, courts almost always dismiss the case. This is why confirming your deadline early is so important.
No. Filing a claim, exchanging letters, or negotiating a settlement does not pause or reset the statute of limitations. Only filing a lawsuit in the proper court before the deadline preserves your right to sue.
Government entities are shielded by sovereign immunity and consent to be sued only under their tort-claims acts, which usually require a formal notice of claim within a short window — often six months to a year. Transit agencies frequently add their own rules. Missing the notice step can bar the claim entirely, so these matters need attention right away.
Wrongful-death claims have their own limitation period, often measured from the date of death rather than the date of injury, and survival actions may follow a separate rule. Treat them as distinct from a standard injury deadline and confirm the specifics with a licensed attorney.
