Quick definition
A statute of limitations is a law that limits the time allowed to begin a legal action or prosecution. The applicable period and start date vary by claim, jurisdiction, defendant, and facts, and missing the deadline can bar the matter.
A statute of limitations is a deadline for starting a legal claim or prosecution. Missing it can prevent a court from considering the merits, even when the underlying facts might otherwise support relief.
There is no single national deadline. The period depends on the jurisdiction, cause of action, defendant, age and capacity of the claimant, date the claim accrued, discovery rules, tolling rules, and special statutes.
What Is a Statute of Limitations?
A statute of limitations is a law limiting the time within which a legal action must be commenced. The clock often starts when a claim “accrues,” but determining accrual can be complex.
Deadline warning: Never calculate a filing deadline from a general article alone. Verify the current statute, court rules, facts, and any pre-suit notice requirement.
Why Do Limitation Periods Exist?
When Does the Clock Start?
The start date is often called accrual. Depending on the claim, accrual may occur when the wrongful act happened, when injury occurred, when damage was or should have been discovered, when a contract was breached, when payment became due, or when a statutory event occurred.
| Concept | General idea | Why it matters |
|---|---|---|
| Occurrence rule | Clock starts when the act or injury occurs | The deadline may run before all consequences are known |
| Discovery rule | Clock may start when the claimant discovered or reasonably should have discovered key facts | Application and scope vary |
| Continuing violation | Some repeated or ongoing conduct may affect timing | Not every continuing effect extends a deadline |
| Accrual by statute | A law specifies the triggering event | Exact statutory language controls |
What Is Tolling?
Tolling pauses, delays, or extends a limitation period in circumstances recognized by law. Examples may involve minority, incapacity, fraudulent concealment, absence from the jurisdiction, bankruptcy stays, military service, agreed tolling, or another statute.
Tolling is highly technical. A person should not assume that negotiations, an insurance claim, a complaint to an agency, illness, or lack of knowledge automatically stops the clock.
Statute of Limitations vs Statute of Repose
| Deadline | Usually linked to | General feature |
|---|---|---|
| Statute of limitations | Accrual or discovery of a claim | May be affected by discovery or tolling rules |
| Statute of repose | A defendant’s act, completion, sale, or other fixed event | Often creates an outer cutoff regardless of later discovery |
Civil and Criminal Deadlines
Civil limitation periods govern claims such as injury, contract, fraud, property, employment, professional malpractice, and statutory rights. Criminal limitation periods govern how long the government has to commence prosecution for an offense, with different periods and possible exceptions for particular crimes.
Filing an administrative charge may be required before a lawsuit and can have its own deadline. The time for an appeal is different from the statute of limitations and is often much shorter.
Claims Against Government Entities
Claims involving a city, county, state, federal agency, public hospital, school, police department, or government employee may require a written notice or administrative claim before a lawsuit. These notice periods can be shorter than the ordinary limitation period.
Act promptly. Identifying the correct government entity and notice procedure can be difficult, and naming the wrong entity may not preserve the claim.
Does Filing Always Meet the Deadline?
Rules differ on whether a case is commenced by filing, service, both, or another act. An incorrect court, rejected filing, unpaid fee, missing signature, defective complaint, unnamed defendant, or failed service can create disputes over timeliness.
Electronic filing timestamps, weekend and holiday rules, extensions, amended pleadings, relation-back rules, removal, and refiling statutes may also matter.
What to Do When a Deadline May Apply
Preserve the date information
Write down every event, discovery date, notice, denial, payment, communication, and deadline.
Identify the exact claim and defendant
Different legal theories and defendants can have different periods.
Check pre-suit requirements
Look for notices, administrative charges, demand letters, certificates, or exhaustion rules.
Use current primary law
Verify statutes and court rules for the correct jurisdiction.
Get prompt advice
Do not wait for the end of a possible period; facts and documents take time to evaluate.
Why Prompt Legal Advice Matters
A lawyer can analyze accrual, tolling, repose, government notice, jurisdiction, choice of law, filing and service rules, and alternative claims. See when to seek legal advice.
Key takeaway: A statute of limitations can end a claim before a court evaluates who was right. Because the correct period and start date are fact-specific, treat uncertainty as urgent.
