A statute of limitations is a legal deadline that caps how long you have to file a lawsuit or bring criminal charges after an event occurs. Miss it, and the claim is effectively dead, no matter how strong the evidence. The specific length depends on the type of claim: as little as one year for some minor offenses, no limit at all for murder, and everything in between for ordinary civil disputes. Just as important as the length are the rules that govern when the clock starts, when it pauses, and what can restart it.
When the Clock Starts
The deadline begins at “accrual,” meaning the moment you gain the legal right to bring a claim. For most situations, that is the date the harm actually happens. If someone rear-ends your car, the clock starts at impact. If a business breaks a contract, it starts on the date of the breach.
For federal civil claims that don’t carry their own built-in deadline, a default rule gives you four years from accrual, covering civil actions arising under federal laws enacted after December 1, 1990, unless Congress set a different timeline.1Office of the Law Revision Counsel. 28 USC 1658 – Time Limitations on the Commencement of Civil Actions Arising Under Acts of Congress
The Discovery Rule
Some injuries don’t announce themselves. A surgeon might leave a sponge inside a patient’s body, and the patient won’t know until a scan years later reveals it. In that kind of case, the discovery rule shifts the starting date to when you actually discovered the harm, or when a reasonable person in your position should have discovered it. The rule shows up most often in medical malpractice, toxic exposure, and fraud, where the damage is hidden by its nature.
Courts examine whether you exercised reasonable diligence. You can’t ignore obvious warning signs for years and then claim ignorance. The rule adjusts for genuinely concealed injuries, not for people who weren’t paying attention.
Claims Against the Government Have Their Own Rules
If your claim targets a federal agency, the timeline is tighter and adds a procedural hurdle. Under the Federal Tort Claims Act, you must file a written administrative claim with the responsible agency within two years of accrual. If the agency denies the claim, you then have just six months to file a lawsuit in court.2Office of the Law Revision Counsel. 28 USC 2401 – Time for Commencing Action Against United States Many state and local governments impose similarly compressed notice requirements, sometimes as short as six months. Skipping the administrative step is one of the most common ways people lose an otherwise valid claim against a public agency.
When the Clock Pauses
Tolling is a temporary freeze on the countdown. Unlike accrual, which sets the starting line, tolling stops a clock that is already running or prevents it from starting even though an injury has occurred. A handful of situations can trigger a pause.
Minors and People Who Can’t Act for Themselves
A young child can’t hire an attorney or navigate a courtroom. When the injured person is a minor, the filing deadline is frozen until they reach the age of majority, which is 18 in most places. The same logic applies when someone lacks the mental capacity to understand their legal rights or manage their affairs; the clock can pause until they recover or a guardian is appointed to act on their behalf.
Defendants Who Flee or Evade Service
If the person who caused your injury leaves the jurisdiction or goes into hiding to avoid being served, the clock stops. Federal law is blunt: no statute of limitations runs in favor of anyone fleeing from justice.3Office of the Law Revision Counsel. 18 USC 3290 – Fugitives From Justice Physical absence from the jurisdiction isn’t even required. Actively evading service while staying nearby counts too.4Department of Justice. Criminal Resource Manual 657 – Tolling of Statute of Limitations
Active-Duty Military Service
Under the Servicemembers Civil Relief Act, time spent on active military duty does not count toward any filing deadline. The protection applies to lawsuits both by and against the servicemember, in state and federal proceedings alike.5Office of the Law Revision Counsel. 50 USC 3936 – Statute of Limitations The one exception is tax deadlines. IRS timelines keep running regardless of military status.
How Long You Actually Get
Legislatures assign different deadlines based on the type of claim, reflecting judgments about how long evidence stays reliable and how urgently different wrongs demand resolution. The ranges below are national generalizations. Your specific state may fall outside them.
Civil Claims
Personal injury claims (car accidents, slip-and-falls, assault) carry deadlines of one to six years, with two to three years being most common. Written contracts get longer, often four to ten years, because the terms are documented and the evidence doesn’t degrade as quickly. Oral contracts receive shorter windows, typically two to six years, since proving their terms grows harder with time. For sales of goods, the Uniform Commercial Code sets a four-year default that most states have adopted, though parties can agree in the original contract to shorten it to as little as one year.
Medical malpractice deadlines range from roughly one to ten years, though the discovery rule frequently extends the effective deadline when a surgical error or misdiagnosis wasn’t immediately apparent. Debt collection lawsuits follow the contract timelines for the underlying obligation, so once the applicable period expires, a creditor loses the legal ability to sue for repayment.
Criminal Charges
Criminal statutes of limitations scale with the severity of the offense. Misdemeanors must be charged within one to two years in most places. Felonies get longer windows, commonly three to seven years, with some jurisdictions allowing up to ten. The most serious offenses have no deadline at all. Under federal law, any crime punishable by death can be prosecuted at any point.6Office of the Law Revision Counsel. 18 USC 3281 – Capital Offenses For non-capital federal crimes, the general deadline is five years from when the offense was committed.7Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital Most states similarly eliminate the deadline for murder, and many have done the same for sexual offenses against children.
The Deadline Isn’t Self-Enforcing
This catches most non-lawyers by surprise: courts don’t police filing deadlines on their own. The statute of limitations is an “affirmative defense,” which means the defendant must raise it explicitly or lose it. Federal Rule of Civil Procedure 8(c)(1) lists the statute of limitations among the defenses a defendant must assert in their answer to a lawsuit.8Legal Information Institute. Federal Rules of Civil Procedure Rule 8 – General Rules of Pleading
If a defendant forgets to include this defense, it is waived permanently. The case then proceeds on its merits even if the filing was years late. That happens more often than you would expect, particularly with unrepresented defendants who don’t realize the deadline passed and that they have to say so. A judge will not rescue a defendant from this oversight.
What Happens When the Deadline Expires
Once the filing window closes, the legal system will no longer provide a remedy for the underlying harm. A court must dismiss the case if the defendant raises the expired deadline, no matter how compelling the evidence. The procedural bar prevents the merits from ever being evaluated.9Legal Information Institute. Constitution Annotated Amendment 14 – Statutes of Limitations and Procedural Due Process A person entitled to a significant insurance payout or contract judgment will recover nothing once the window closes.
There is no partial credit for filing late, no judicial discretion to overlook the problem because the case has merit, and no second chance to refile. Defendants know this, and they routinely move for dismissal before trial as the first line of defense.
Equitable Estoppel: A Narrow Exception for Defendant Misconduct
There is one escape valve, and it is a narrow one. If the defendant actively misled you into missing the deadline through fraud, concealment, or false promises that discouraged you from filing, they may be barred from using the expired statute of limitations as a shield. This doctrine, called equitable estoppel, exists because courts will not let someone profit from their own deception.
Equitable estoppel requires more than silence. You have to show that the defendant took specific, affirmative steps to prevent you from filing on time. A company that actively suppressed evidence of a defective product, for example, might be estopped from invoking the deadline. A defendant who simply failed to volunteer information about the harm they caused usually faces no estoppel. The burden to investigate still falls on you, and courts draw a firm line between active deception and passive silence.
Two Common Traps
Partial Payments Can Restart a Debt Clock
An expired statute of limitations on a debt means a creditor can no longer sue you to collect. But the debt itself doesn’t vanish, and the clock can be reset. In many states, making a partial payment, signing a written acknowledgment that you owe the money, or entering a new agreement to pay can restart the filing deadline from scratch. Some debt collectors understand this dynamic and will push for any small payment precisely because it revives their ability to sue.
A $25 “good faith” payment on a debt that has been legally uncollectible for years can suddenly reopen the window for a lawsuit over the full balance. If a collector contacts you about old debt, find out whether the statute of limitations has already expired before paying anything or acknowledging the obligation. The rules for what restarts the clock vary by state, so the safest approach is to get the details in writing and talk to an attorney before responding.
Statutes of Repose Are a Harder Deadline
A statute of repose looks similar to a statute of limitations but works differently in one critical way: the discovery rule cannot extend it. A statute of limitations typically starts when you discover your injury (or should have). A statute of repose starts from a fixed event like the date a product was sold, a building was completed, or a medical device was implanted, and it runs whether or not anyone has been hurt yet.
That means a statute of repose can expire before you even know you have a claim. If a building has a ten-year statute of repose measured from substantial completion, and a hidden structural defect causes a ceiling collapse in year eleven, you may have no recourse at all. Courts treat statutes of repose as substantive limits on liability rather than procedural deadlines, which makes them far harder to work around. They show up most often in construction defect and product liability cases, and the length varies significantly by jurisdiction and claim type.
