What Is a Statute of Limitations?

A complete, plain-English guide to one of the most important — and most misunderstood — rules in American law.

Key Takeaway: A statute of limitations is a law that sets a strict deadline for filing a lawsuit. Once this deadline passes, you permanently lose the right to sue — regardless of how strong your case is. These deadlines vary by state and case type, ranging from 1 year to 15 years.

The Definition: What Is a Statute of Limitations?

A statute of limitations is a law that establishes the maximum amount of time a person has to initiate legal proceedings after an injury, breach, or wrongful act. The term comes from the Latin statuta limitationis — literally, "established limits."

Every US state has its own set of statutes of limitations for civil claims. These laws set specific deadlines — measured in years — that vary based on the type of claim and the state where the claim arose. A personal injury claim in California has a 2-year deadline. The same claim in Maine gets 6 years. A written contract dispute in Rhode Island gets 10 years. These are not arbitrary numbers — they reflect each state legislature's policy judgment about how long is reasonable to bring a claim.

The consequences of missing a statute of limitations deadline are severe and largely irreversible. If you file even one day late, the defendant will file a motion to dismiss, and the court will almost certainly grant it. Your case is over — regardless of how clearly you were wronged, how strong your evidence is, or how serious your injuries are.

Why Do Statutes of Limitations Exist?

Statutes of limitations exist for three main policy reasons:

📜 Evidence Preservation

Evidence degrades over time. Witnesses' memories fade, documents are lost or destroyed, physical evidence deteriorates, and security footage is overwritten. Requiring timely claims ensures disputes are resolved while the evidence is still fresh enough to support a fair result.

⚖️ Fairness to Defendants

Defendants deserve protection from indefinite legal exposure. People and businesses need to be able to arrange their affairs without facing the permanent threat of litigation for events that may have occurred decades ago. At some point, the right to certainty outweighs the right to sue.

🏛️ Judicial Efficiency

Courts are already overburdened. Permitting ancient claims would further overload the system while producing unreliable results. Statutes of limitations help ensure that courts spend their time on timely disputes where the evidence still supports meaningful adjudication.

How Statutes of Limitations Work: The Basics

Every statute of limitations has three key components:

ComponentWhat It MeansExample
The PeriodHow many years you have to file2 years for personal injury in California
The TriggerWhen the clock starts runningDate of injury (or date of discovery)
The ExceptionsRules that pause or extend the deadlineTolling for minors, discovery rule, government notice

Step 1: Identify Your Case Type

Different types of civil claims have different limitation periods — even in the same state. The most common civil case types and their typical ranges (across all states) are:

Case TypeTypical RangeMost Common
Personal Injury1–6 years2 years
Medical Malpractice1–7 years2–3 years
Written Contract3–15 years4–6 years
Oral Contract2–6 years3–4 years
Defamation (Libel/Slander)1–3 years1–2 years
Wrongful Death1–3 years2 years
Property Damage2–6 years3 years
Fraud2–7 years3–6 years (from discovery)

Step 2: Determine When the Clock Started

The most common trigger is the date of the injury or wrongful act. However, many states modify this with the discovery rule — particularly for cases where the harm was not immediately apparent. Under the discovery rule, the clock starts when you discovered (or with reasonable diligence should have discovered) that you were harmed and who may be responsible.

Step 3: Check for Exceptions and Tolling Rules

Several conditions can pause or extend the limitations period. These are called tolling rules:

  • Minority: The clock is typically paused while the injured person is under 18. It begins running on their 18th birthday.
  • Mental incapacity: Legal incapacity may toll the period until capacity is restored.
  • Fraudulent concealment: If the defendant actively hid their wrongdoing, courts may extend the deadline.
  • Absence of defendant: If the defendant left the state after the incident, some states toll the period during their absence.
  • Government claims: Claims against government entities often require a separate Notice of Claim filed within 60–180 days — before the regular limitations period matters.

What Happens When the Statute of Limitations Expires?

The statute of limitations is an affirmative defense — meaning the defendant must raise it. If you file a lawsuit after the deadline, the defendant (or their attorney) will file a motion to dismiss citing the expired limitations period. Courts virtually always grant these motions. The result is:

  • Your case is dismissed with prejudice — permanently. You cannot refile.
  • The dismissal is based solely on the timing — not the merits of your case.
  • A meritorious claim with overwhelming evidence is dismissed just as readily as a weak one.
  • Your attorney (if you have one) may face a malpractice claim for allowing the deadline to pass.

⚠️ Critical Caution

Hiring an attorney, sending a demand letter, or opening an insurance claim does NOT stop the statute of limitations clock. Only filing a complaint with the court stops the clock. Even if you're in active settlement negotiations, you must file before the deadline if a settlement isn't reached in time.

Civil vs. Criminal Statutes of Limitations

This guide — and this website — covers civil statutes of limitations only. Criminal statutes of limitations are separate laws governing how long prosecutors have to bring criminal charges. They operate differently:

FeatureCivil SOLCriminal SOL
Who files?The injured party (plaintiff)Government prosecutors
PurposeCompensation for harmPunishment / public protection
Murder/serious feloniesN/A (civil case)Often no statute (no SOL)
Waivable by defendant?YesGenerally no

Statutes of Limitations vs. Statutes of Repose

These two legal concepts are often confused but are importantly different:

Statute of Limitations

  • Starts running from the date of injury or discovery
  • Can be paused (tolled) by minority, mental incapacity, concealment, etc.
  • Plaintiff-friendly in that discovery rule can delay the start

Statute of Repose

  • Starts running from the date of the defendant's act
  • Generally cannot be tolled — it is an absolute outer limit
  • Common in medical malpractice and products liability cases
  • Example: A 7-year repose bars all claims filed more than 7 years after the negligent act, regardless of when harm was discovered

Frequently Asked Questions

Yes. Every state sets its own statutes of limitations, and they vary significantly. For example, personal injury deadlines range from 1 year in Kentucky and Tennessee to 6 years in Maine and North Dakota. Written contract deadlines range from 3 years to 15 years. Always check the specific law for the state where your claim arose.

The defendant can waive the statute of limitations by failing to raise it as a defense. Parties can sometimes contractually agree to shorter limitations periods. Courts can extend deadlines through tolling in specific circumstances (minors, mental incapacity, fraudulent concealment). However, you cannot unilaterally extend the deadline — you must file or demonstrate a valid tolling doctrine applies.

As a general rule, the statute of limitations of the state where the injury occurred governs. But in multi-state situations, courts apply complex "choice of law" analysis. If your incident crossed state lines, consult an attorney to determine which state's law applies before calculating your deadline.

Yes. Federal claims often have their own limitations periods set by federal statute. For example, Section 1983 civil rights claims borrow the forum state's personal injury period. Federal tort claims against the federal government are governed by the Federal Tort Claims Act, which has its own rules and notice requirements. Federal contract and fraud claims vary by statute.
