Yes, you can sometimes sue for something that happened years ago, but whether the case survives depends on the deadline for that specific type of claim and whether any legal doctrine paused or extended the clock in your situation. Filing deadlines run from as short as one year to as long as fifteen years, and a handful of exceptions can either delay when the countdown started or reopen a window that already closed.
The Deadline Is the First Question
Every lawsuit has a filing deadline called a statute of limitations. Once it passes, the other side can ask the court to throw the case out. The clock usually starts on the date of the injury or breach, though several exceptions covered below can shift that starting point.
One point most people miss: an expired statute of limitations does not automatically kill your case. Under federal court rules, it is an “affirmative defense,” meaning the defendant has to raise it or waive the right to use it.1Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading If the defendant never brings it up, a judge generally will not dismiss on that basis. In practice, any defendant with a lawyer will raise it immediately, so do not plan around this.
How Long You Actually Have
Deadlines vary sharply by claim type and state. The ranges below are general; your state’s exact number could fall anywhere inside them.
Personal Injury
Most states give you two to three years to file a personal injury lawsuit. A few outliers allow only one year, and a couple stretch to six. For car accidents, medical treatment, or defective products, the clock usually starts on the date of the injury, subject to the discovery rule below.
Breach of Contract
Contract claims run longer. Oral agreements typically get three to six years. Written contracts commonly get four to ten years, with a handful of states allowing up to fifteen. Which category your agreement falls into matters, because courts treat written and oral contracts differently on timing.
Workplace Discrimination
Employment discrimination has short deadlines and an extra administrative step. You generally must file a charge with the Equal Employment Opportunity Commission within 180 days of the discriminatory act, extended to 300 days if your state has its own anti-discrimination agency.2U.S. Equal Employment Opportunity Commission. Time Limits For Filing A Charge Federal employees have just 45 days to contact their agency’s EEO counselor. Miss these and the claim is likely gone, even if stronger evidence surfaces later.
Claims Against the Federal Government
Suing the federal government requires you to file an administrative claim in writing within two years of the incident.3Office of the Law Revision Counsel. 28 U.S. Code 2401 – Time for Commencing Action Against United States If the agency denies it, you have six months to file the actual lawsuit. Many people spend months preparing a suit without realizing the agency paperwork had to come first.
Environmental Contamination
Federal environmental claims under CERCLA give you three years from the date you discover the harm and its connection to a contamination release.4Office of the Law Revision Counsel. 42 U.S. Code 9613 – Civil Proceedings The discovery-based trigger exists because contamination can go undetected for decades.
What Can Pause or Restart the Clock
Several doctrines exist specifically to protect people who could not reasonably have filed on time. If one of these fits your situation, an old claim may still be viable.
The Discovery Rule
The most common exception delays the start of the limitations period until you knew, or reasonably should have known, about the injury. Medical malpractice is the classic example. A surgeon might leave a sponge inside you, but symptoms may not appear for years. Under the discovery rule, your clock starts when you learn about the problem, not when the surgery happened. Most states apply some version of this, though some limit it to specific claim types like medical malpractice or fraud.
Minors and Incapacitated Individuals
If you were a minor when the injury occurred, most states pause the deadline until you turn eighteen. A parallel rule applies to people who were mentally incapacitated at the time. The clock starts running once the disability ends, and you get the full limitations period from that point.
Military Service
The Servicemembers Civil Relief Act excludes any period of active-duty military service from the statute of limitations calculation.5Office of the Law Revision Counsel. 50 U.S. Code 3936 – Statute of Limitations If you were deployed when the deadline would have run, your time is preserved until service ends. This applies to state and federal claims but not to tax deadlines.
Fraudulent Concealment
When a defendant actively hides their wrongdoing, the clock can pause until you discover, or reasonably should have discovered, the fraud. Mere silence is not enough. The defendant must have taken affirmative steps to keep you from learning about the claim. A doctor who alters records to cover up a mistake, for instance, cannot later argue you filed too late. The pause lasts while the concealment continues and lifts once you uncover the truth.
Tolling Agreements
Sometimes both sides sign a written agreement to pause the clock while they negotiate or investigate. These voluntary tolling agreements are contracts that freeze the deadline for a set period, giving both parties room to work without forcing a rushed filing. They are common in business disputes where the parties have an ongoing relationship.
The Hard Cutoff That Exceptions Cannot Beat
A statute of repose sits behind the statute of limitations and functions as an absolute outer wall. None of the pauses and extensions above apply to it. No discovery rule, no fraudulent concealment, no equitable arguments. Once the repose period runs, the claim is gone.
Statutes of repose show up most in product liability and construction defect cases. Roughly half the states impose a repose period for product liability, typically eight to fifteen years after the product was first sold or delivered. Construction defect repose periods commonly run four to fifteen years after the project is completed. The practical effect: if a building’s foundation cracks twelve years after construction in a state with a ten-year repose period, you have no claim against the builder, regardless of when you noticed the damage.
Revival Windows for Childhood Sexual Abuse
One area has moved in the opposite direction. Over the past two decades, many states have enacted revival statutes that temporarily reopen filing windows for survivors of childhood sexual abuse, even for claims that expired decades ago. At least fifteen states have eliminated statutes of limitations for civil childhood sexual abuse claims entirely, and more than thirty have created temporary revival windows allowing previously barred claims to proceed.6Consumer Attorneys of California. Sexual Assault Survivors’ Rights
These revival windows usually stay open for a set period, often two to three years. During that window, survivors can file claims that would otherwise be time-barred. If your state has opened one, the deadline for filing inside that window is itself firm. Miss it and the claim is likely gone for good.
Even a Timely Old Claim Is Hard to Win
Clearing the deadline is only the first hurdle. Suing over something that happened years ago runs into real problems that courts recognize.
Evidence Fades
Time degrades cases in ways that are hard to overcome. Witnesses forget details, change their stories, or become unreachable. Physical evidence deteriorates or gets thrown out. Documents disappear. Many old claims fail not on a legal technicality but because the plaintiff can no longer prove what happened. If you are thinking about a delayed claim, securing whatever evidence still exists should come first. Certified records, saved emails, photographs, and written witness statements all become more valuable the older the case gets.
Medical records deserve their own attention. Federal rules require most healthcare providers to retain records for at least five to six years, and many states impose longer periods.7CMS. Medical Record Retention and Media Format for Medical Records If your claim depends on them, request copies now rather than assuming they will still be there later.
The Laches Defense
Even when the statute of limitations has not technically run, a defendant can argue that your unreasonable delay has caused them unfair prejudice. This equitable defense, called laches, asks the court to bar the claim because waiting so long made a fair defense impossible. A defendant might point to key witnesses who have died, records destroyed in the ordinary course of business, or major financial decisions made on the assumption of no lawsuit. Laches comes up most in property disputes, intellectual property, and other equitable claims where statutes of limitations may not apply directly.
Sanctions for Filing Anyway
Filing a lawsuit you know is time-barred can backfire. Federal courts can impose sanctions on attorneys or parties who file frivolous pleadings, including claims with no legal basis.8Legal Information Institute. Federal Rules of Civil Procedure Rule 11 – Signing Pleadings, Motions, and Other Papers; Representations to the Court; Sanctions Sanctions can include monetary penalties, payment of the other side’s attorney fees, or mandatory legal education. An attorney who knowingly files a time-barred claim also risks professional discipline.
Before spending time and money on a delayed claim, pin down three things: the exact deadline for your type of claim in your state, whether any tolling doctrine applies to your situation, and whether a statute of repose sits behind that deadline. The answers determine whether you have a case worth filing or a claim the courts will refuse to hear.
