Definition
A statute of limitations is a law that sets the maximum period of time within which a party must bring a legal claim. Once the limitations period expires, the claim is time-barred and the right to sue — even on an otherwise valid cause of action — is extinguished or rendered unenforceable. The limitations period begins to run when the cause of action accrues, which is typically when the injury occurs or, under the discovery rule, when the injured party knew or reasonably should have known of the harm.
Statutes of limitations apply in both civil and criminal contexts, though their function differs slightly in each:
(1) Civil. A plaintiff who fails to file suit within the applicable period loses the right to pursue the claim in court. The defendant may raise expiration of the limitations period as an affirmative defense. The court does not apply the limitation on its own motion; the defendant must assert it or it may be waived.
(2) Criminal. Prosecutors must bring charges within the statutory period following the alleged offense. Certain serious crimes — including murder in most jurisdictions — carry no limitations period and may be prosecuted at any time.

Common Language
Modern common usage (Wiktionary): A law passed by a legislative body that sets a maximum time limit after an incident, in which legal proceedings may be initiated.
Historical common usage (Webster's 1913): The term "statute of limitations" does not appear as a distinct entry in Webster's 1913, reflecting its status as a term of art rather than ordinary language at that time.
The common definition is accurate as far as it goes, but it understates two critical legal dimensions: first, that the period can be tolled — paused or extended — by specific circumstances such as the plaintiff's minority, fraudulent concealment by the defendant, or the discovery rule; and second, that the consequences of expiration differ by jurisdiction, with some treating the lapsed claim as procedurally barred and others treating the underlying right itself as extinguished.

Common Confusion
Statute of Limitations vs. Statute of Repose. These two devices are frequently conflated but operate differently. A statute of limitations begins running when the cause of action accrues and is subject to tolling doctrines. A statute of repose sets an absolute outer deadline measured from a fixed event — typically the defendant's act, such as completion of construction or sale of a product — regardless of when the plaintiff discovered the injury and regardless of tolling. A statute of repose can bar a claim before it has even accrued. Researchers working in products liability, construction defect, and medical malpractice sources must distinguish the two carefully; historical sources often use "limitation" loosely to cover both.
Statute of Limitations vs. Laches. Laches is an equitable doctrine that bars a claim when a plaintiff's unreasonable delay has prejudiced the defendant. Unlike a statute of limitations, laches does not operate by fixed time period and applies primarily in equity. Courts sometimes apply both analyses to the same claim, particularly in intellectual property disputes.

Why It Matters in Research
Accrual doctrines shift the analysis. When a limitations period begins running is as important as how long it runs. Early common law used a strict injury-based accrual rule. The discovery rule — which delays accrual until the plaintiff knew or should have known of the harm — developed unevenly across jurisdictions and claim types. Researchers reading pre-twentieth-century cases must not assume modern accrual doctrine applies.
Tolling creates hidden complexity. Equitable tolling, statutory tolling for minority or incompetency, and tolling for fraudulent concealment can dramatically alter whether a claim is time-barred. Older sources may not reflect the full scope of modern tolling doctrine; conversely, some tolling doctrines recognized in earlier common law have been narrowed or abolished by statute.
Jurisdictional variation is substantial. Federal courts apply state statutes of limitations for most state-law claims under Erie, but federal law governs accrual in some federal question contexts. Limitations periods for the same cause of action can range from one to ten years depending on the jurisdiction and the nature of the claim. Historical sources predating Erie apply a different choice-of-law framework entirely.
Tax research requires separate treatment. The IRS operates under its own statutory limitations framework with distinct rules for assessment and collection. These periods are subject to special tolling events — agreements to extend, bankruptcy filings, and pending litigation — that do not map onto civil litigation limitations doctrine. See tax_173 and tax_174 in the Law Mind Tax Encyclopedia.
Criminal vs. civil period length. Historical sources often discuss criminal and civil limitations periods in the same breath without flagging that they operate under different policy rationales and procedural rules. The distinction matters when characterizing the nature of a proceeding or when a single set of facts could give rise to both civil liability and criminal prosecution.

Historical Dictionary Support
Black's Law Dictionary identifies the core function accurately: a statute of limitations is one that declares no suit shall be maintained on certain causes of action unless brought within a specified period after the right accrued. This formulation captures the claim-specific nature of the device — different periods apply to different causes of action — and correctly anchors the clock to accrual rather than to filing of a complaint or service of process.
Bouvier's Law Dictionary redirects entirely to LIMITATIONS, which was the more conventional term of art in the nineteenth century. Researchers using Bouvier should follow that cross-reference; the underlying discussion there covers the historical common-law backdrop, including the foundational English statutes that American limitations law derived from.
Burrill's Law Dictionary's entry, as captured here, veers into maxims of statutory construction (including the well-known canon that an affirmative statute does not derogate from the common law) rather than directly defining the doctrine. This is characteristic of Burrill's more scholastic approach and is useful for understanding the interpretive framework courts applied to limitations statutes in the nineteenth century, but it does not supply a working definition of the doctrine itself.
Collectively, the historical dictionaries reflect an era when limitations law was primarily statutory in character but heavily interpreted through common-law canons. The modern doctrinal architecture — discovery rule, equitable tolling, class-action tolling, relation-back doctrine — is largely absent from these sources and must be sourced from case law and more recent treatises.

Jurisdictional Note
Limitations periods vary significantly by claim type and jurisdiction. Personal injury claims typically range from one to six years; contract claims from three to ten years; and some specialized claims — securities fraud, civil RICO — are governed by federal statutes with their own accrual and tolling rules. Researchers must identify both the applicable limitations period and the governing accrual doctrine for the specific jurisdiction and cause of action at issue.
