A statute of limitations is a law that sets a hard deadline for filing a lawsuit or bringing criminal charges. Miss it, and the case is over before a judge ever looks at the evidence. The length of the deadline depends on what kind of claim you have, where you’re filing it, and when the law says your clock started running, and a handful of exceptions can pause that clock or, in rare situations, remove the deadline entirely.
What a Statute of Limitations Is
A statute of limitations puts an expiration date on the right to use the court system. Once the window closes, the defendant can ask the court to throw the case out, and the court will do so without evaluating the merits. One day late is as fatal as ten years late.
For civil claims arising under federal laws that don’t specify their own deadline, the default window is four years from the date the claim arises.1Office of the Law Revision Counsel. 28 USC 1658 – Time Limitations on the Commencement of Civil Actions Arising Under Acts of Congress States set their own deadlines for state-law claims, and the variation is wide.
One technical detail worth knowing: a statute of limitations is an affirmative defense. The defendant has to raise it in their response to the complaint. If they don’t, the case moves forward as if the deadline never existed.2Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading In practice, defendants and their lawyers rarely miss this, so plaintiffs cannot plan around the possibility.
Why the Deadlines Exist
Evidence deteriorates. Physical proof is lost, documents get purged, digital records disappear during system upgrades, and witness memory fades fast. Courts that decide cases on degraded evidence produce unreliable outcomes, and the legal system has recognized that problem for centuries. The deadlines also give people, businesses, and professionals a point at which they can close the book on past conduct instead of living under indefinite exposure to a lawsuit.
How Long You Have for Civil Claims
Civil deadlines turn on the type of claim and the state. Some general patterns hold.
- Personal injury: Most states give you between two and three years from the date of injury. A few allow longer. The shorter windows reflect how quickly physical evidence and medical records lose their reliability.
- Written contracts: Typically four to six years. Oral contracts usually get shorter deadlines because they’re harder to prove over time.
- Sale of goods: The Uniform Commercial Code, adopted in some form by every state, sets a four-year deadline for disputes over the sale of goods.
- Property damage: Generally falls between personal injury and contract ranges, depending on the state.
- Professional malpractice: Medical and legal malpractice claims often have their own specialized deadlines, sometimes shorter than the general personal injury window.
- Employment discrimination: Federal discrimination claims run on a much shorter timeline. You generally have 180 days from the discriminatory act to file a charge with the Equal Employment Opportunity Commission, extended to 300 days if your state has its own anti-discrimination agency covering the same conduct.3U.S. Equal Employment Opportunity Commission.

Claims against government entities often come with much shorter deadlines and separate notice-of-claim requirements that must be met well before any lawsuit is filed. Check these first if a city, county, state, or federal agency is involved.
How Long Prosecutors Have for Criminal Charges
Criminal cases run on their own clocks, and the severity of the offense controls the deadline. The federal default is five years. If prosecutors don’t secure an indictment within five years of a non-capital offense, they’re barred from pursuing the case.4Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital Many states follow a similar structure with different specific periods.
Misdemeanors typically carry deadlines of one to two years. Serious felonies get longer windows, sometimes a decade or more.
Murder and other capital offenses have no federal statute of limitations at all. An indictment for an offense punishable by death can be brought at any time.5Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses Most states follow the same approach for murder, and many extend the no-limit rule to certain sexual offenses against children and terrorism-related charges.
When the Clock Starts
The default rule is that the clock starts on the date the harm occurred: the day of the accident, the date the contract was breached, the moment the crime was committed. Lawyers call this accrual. Two exceptions matter.
The Discovery Rule
The discovery rule delays the start of the clock until you knew, or reasonably should have known, that you were harmed and that someone else’s conduct caused it. It exists because expecting someone to sue over an injury they don’t yet know about makes no sense.
Medical malpractice is the classic illustration. If a surgeon leaves an instrument inside you in January but you don’t develop symptoms until November, the clock starts in November, not January. The “reasonably should have known” piece has teeth, though. If you had symptoms that would have prompted a reasonable person to investigate and you ignored them, a court may decide the clock started when the symptoms first appeared.
The Continuing Violation Doctrine
Some conduct plays out over weeks, months, or years instead of in a single moment. Workplace harassment is the most common example. Under the continuing violation doctrine, if the last incident of ongoing harassment falls within the filing window, the entire pattern can be included in the claim.
One-time acts of discrimination work differently. A firing, a denied promotion, or a refused transfer starts its own individual clock, and you can’t fold a years-old termination into a current harassment claim just because harassment also happened recently. Older incidents can still serve as background evidence supporting a timely claim.
What Pauses the Clock
Certain circumstances freeze the limitations period temporarily. Lawyers call this tolling. When the condition is resolved, the remaining time picks up where it left off.
- Minors: If the person with the claim is under 18 when the harm occurs, the clock typically pauses until they reach adulthood. A child injured at age 10 in a state with a two-year personal injury deadline wouldn’t face that countdown until turning 18.
- Mental incapacity: If a person lacks the legal capacity to manage their own affairs when the claim arises, the clock generally pauses until capacity is restored or a legal representative is appointed.
- Defendant’s absence: When a defendant leaves the state or hides to avoid being served, most states stop the clock until that person can be located. Federal law tolls the criminal limitations period when a defendant flees or is outside the United States.
Weekends and Holidays
If your filing deadline lands on a Saturday, Sunday, or federal holiday, you don’t lose a day. Under the Federal Rules of Civil Procedure, the deadline extends to the end of the next business day.6Legal Information Institute. Federal Rules of Civil Procedure Rule 6 – Computing and Extending Time Most state courts follow a similar rule. Relying on this extension is still a poor strategy. E-filing systems crash, postal delays happen, and realizing late on a Friday afternoon that you miscounted the days is not a position you want to be in.
Statute of Repose: The Harder Deadline
A statute of repose looks similar to a statute of limitations but works very differently, and the distinction trips up even experienced lawyers. Both impose filing deadlines. A statute of repose, though, starts running from the defendant’s last act, such as completing a construction project or selling a product, regardless of whether anyone has been injured yet.
This means a statute of repose can expire before you know you’ve been harmed. A building constructed with defective materials may not show problems for 15 years, but if the state’s statute of repose for construction is 10 years from completion, the deadline has already passed when the defect appears. The discovery rule won’t save you. Tolling generally doesn’t apply. The deadline is absolute.
Statutes of repose are most common in construction defect and product liability cases. Typical periods run from 6 to 12 years depending on the state and the type of claim. If you may have a construction or product liability case, check whether your state has a statute of repose in addition to the limitations period.
Laches: Being On Time Isn’t Always Enough
Even when you file within the statute of limitations, a court may still block your claim if you waited too long without a good reason. The doctrine of laches is a judge-made rule that applies primarily in cases seeking equitable relief, such as injunctions or specific performance, rather than money damages.
To succeed on a laches defense, the defendant generally needs to show two things: that the plaintiff’s delay was unreasonable, and that the delay caused real prejudice. Prejudice might mean destroyed evidence, dead witnesses, or significant financial decisions made in reliance on the assumption that no claim was coming. Laches is less predictable than a statute of limitations because it turns on the specific facts and the judge’s view of fairness.
Protecting Your Claim Before the Deadline
The most common way people lose valid legal claims isn’t weak evidence. It’s missing the deadline.
Don’t assume you know your deadline without checking. It depends on the type of claim, the jurisdiction, and sometimes the identity of the defendant. Getting it wrong by a single day ends the claim.
The clock may already be running even if you haven’t finished medical treatment, settled with an insurer, or figured out the full extent of your damages. Settlement talks and insurance claims do not pause the limitations period. Many people discover too late that months of back-and-forth with an adjuster counted against their filing deadline the entire time.
Filing a lawsuit doesn’t mean going to trial. Filing just before the deadline preserves your rights while negotiations continue, and the case can be settled or dismissed later. Once the deadline passes without a filing, there’s nothing left to negotiate with.
