Massachusetts Statute of Limitations: Deadlines by Case Type

Massachusetts statutes of limitations establish the maximum time window within which a legal action must be filed after a claim arises. Missing these deadlines typically results in permanent loss of the right to pursue relief in court, regardless of the underlying merits of the case. This page maps the major deadline categories under Massachusetts law, the mechanisms that can pause or extend those periods, and the structural boundaries that determine which framework applies to a given dispute.

Definition and scope

A statute of limitations is a procedurally binding deadline codified in state law that bars a plaintiff from initiating a civil action — or the Commonwealth from pursuing a criminal prosecution — after a specified period has elapsed from the accrual of the cause of action. In Massachusetts, these deadlines are primarily governed by Massachusetts General Laws (M.G.L.) Chapter 260, which consolidates the majority of civil limitation periods. Separate provisions exist under other chapters for specialized claims, including Chapter 152 (workers' compensation), Chapter 84 (highway defects), and various criminal statutes under Chapter 277.

The scope of this page covers civil and criminal limitation periods applicable under Massachusetts state law. Federal causes of action filed in the United States District Court for the District of Massachusetts operate under separate federal statutes and are not covered here. Claims governed exclusively by federal law — such as civil rights actions under 42 U.S.C. § 1983, federal employment discrimination claims under Title VII, or federal bankruptcy proceedings — fall outside the Massachusetts Chapter 260 framework, though Massachusetts courts may apply state limitation periods to § 1983 claims by borrowing from M.G.L. c. 260, § 5A, which sets a 3-year period for personal injury actions. Parties navigating the intersection of state and federal claims should consult the regulatory context for the Massachusetts legal system for jurisdictional framing.

How it works

The limitations clock in Massachusetts begins running at the moment a cause of action "accrues." Accrual typically occurs when the plaintiff knew or reasonably should have known of the injury and its cause — a standard applied across contract, tort, and property claims under Massachusetts case law interpreting M.G.L. c. 260.

The period can be tolled (paused) by specific statutory and common-law doctrines:

1. Discovery rule — The clock does not begin until the plaintiff discovers, or reasonably should have discovered, the injury. This applies extensively in medical malpractice and latent environmental exposure cases.
2. Minority tolling — Under M.G.L. c. 260, § 7, the limitation period is tolled for minors until they reach age 18, after which the standard period begins running.
3. Insanity or mental incapacity — M.G.L. c. 260, § 7 also tolls limitations when a plaintiff is under a legal disability due to mental incapacity at the time the cause of action accrues.
4. Fraudulent concealment — If a defendant actively conceals the existence of a claim, the period may be tolled under equitable principles recognized in Massachusetts courts.
5. Absence of defendant from Massachusetts — M.G.L. c. 260, § 9 tolls the period during any time the defendant is absent from the Commonwealth.

Once a lawsuit is filed — meaning the complaint is formally submitted to the clerk of the appropriate court as described in the Massachusetts civil procedure overview — the limitations period is satisfied. Filing serves as the operative act; service of process on the defendant does not reset the clock but must follow within the time required by court rules.

Common scenarios

The following breakdown covers the most frequently encountered limitation periods under Massachusetts law, sourced from M.G.L. Chapter 260 and related statutes:

Medical malpractice carries a dual-track deadline: 3 years from discovery under the discovery rule, with an absolute 7-year statute of repose measured from the date of the negligent act — meaning claims cannot be filed more than 7 years after the act regardless of when the injury was discovered, except in cases involving foreign objects left in the body.

Chapter 93A claims — unfair or deceptive trade practices — are governed by a 4-year period under M.G.L. c. 260, § 5A and represent a distinct track from ordinary tort claims. The Massachusetts Chapter 93A consumer protection framework details the substantive elements; the 4-year period applies to private actions by individuals and businesses alike.

Criminal prosecution limits under M.G.L. c. 277 vary significantly. Murder carries no statute of limitations. Rape and certain sex offenses involving victims under age 16 carry extended or eliminated periods. Most felonies carry a 6-year period; most misdemeanors carry a 6-year period as well, though minor misdemeanors may carry shorter windows under specific provisions.

Decision boundaries

Determining which limitation period applies requires resolving threshold classification questions:

Contract vs. tort framing. A claim arising from a professional relationship may sound in both contract and tort. In Massachusetts, the 6-year contract period and the 3-year tort period can run concurrently on overlapping facts. Courts look to the nature of the duty breached — a duty arising solely from agreement invokes contract; a duty imposed by law independent of agreement invokes tort. Massachusetts tort law and Massachusetts contract law each carry different accrual rules that can produce divergent deadlines on functionally identical facts.

The home-front limitation on government defendants. Claims against Massachusetts state agencies or municipalities require compliance with additional presentment requirements. Under M.G.L. c. 258 (the Massachusetts Tort Claims Act), written presentment to the relevant government entity must occur within 2 years of the injury, and suit must be filed within 3 years. Failure to comply with presentment is a jurisdictional bar — not merely a procedural defect — and the court must dismiss the claim.

Federal court vs. state court filing. When a claim is filed in federal court under diversity jurisdiction, the federal court applies the Massachusetts limitation period as substantive law under Erie Railroad Co. v. Tompkins (304 U.S. 64, 1938). However, federal procedural tolling rules — including the relation-back doctrine under Fed. R. Civ. P. 15(c) — may differ from Massachusetts Rules of Civil Procedure Rule 15. Parties litigating in federal courts in Massachusetts must account for this procedural divergence.

Accrual disputes in latent injury cases. The single most litigated boundary question in Massachusetts limitations law is the precise accrual date in latent exposure cases — asbestos, environmental contamination, and pharmaceutical injury. The Massachusetts Supreme Judicial Court has applied the discovery rule to toll these periods, but the outer 7-year repose applicable to medical malpractice does not automatically extend to all latent injury tort claims, creating asymmetry that courts resolve case-by-case.
