The clock starts on the date of injury. The controlling statute is Mass. Gen. Laws ch. 260 § 2A. Filing one day late dismisses the case with prejudice.
Personal-injury cases in Massachusetts live or die by the calendar. The statute of limitations is the single most aggressive procedural defense available to insurers and defense attorneys, and they raise it the moment a complaint is filed even a day late.
Massachusetts applies the same 3-year limitations period to personal injury, medical malpractice, and wrongful-death claims (Mass. Gen. Laws ch. 260 § 2A). Property-damage claims run separately, with a 3-year deadline.
The statute itself, Mass. Gen. Laws ch. 260 § 2A, is the controlling authority. Interpretive decisions come from MA Sup. Jud. Ct., which has repeatedly enforced the deadline against late-filed plaintiffs.
Massachusetts treats the date of injury as the trigger. Settlement negotiations, insurance adjuster calls, and pre-litigation demands do not pause the running of the statute , only proper filing in a Massachusetts court does.
Massachusetts courts recognize a "discovery rule" exception: the statute does not begin running until the plaintiff knew or reasonably should have known of the injury and its cause. This matters most in latent-injury cases like asbestos exposure, surgical sponge cases, or chemical poisoning.
If a complaint is filed after the deadline, the defendant's counsel files a Rule 12(b)(6)-equivalent motion to dismiss. The judge will grant it as a matter of law , there is no judicial discretion to forgive the lateness absent a recognized tolling exception.
For minors, Massachusetts pauses the SOL clock until the child reaches adulthood. Medical-malpractice claims involving minors often have separate, more restrictive tolling rules , see the statute citation below for the specific Massachusetts provisions.
Massachusetts courts have recognized tolling for plaintiffs whose mental condition prevents them from understanding or pursuing their legal rights. The burden of proof is on the plaintiff. Temporary impairment after the accident, such as pain medication or short hospitalizations, does not qualify in most Massachusetts cases.
If the at-fault party leaves Massachusetts after the injury, the SOL is typically tolled for the period of absence. Modern long-arm statutes and the increasing availability of service via the Massachusetts insurance commissioner have narrowed this rule.
If the defendant actively concealed the cause of action, Massachusetts courts can extend the SOL until the concealment is discovered or could have been discovered with reasonable diligence. Passive non-disclosure does not usually qualify.
The Massachusetts Tort Claims Act imposes pre-suit notice requirements on claims against state and municipal defendants. These notices are jurisdictional , failing to serve them on time, in the form required by statute, dismisses the case regardless of the SOL.
The statute of limitations decides whether you can sue. Massachusetts's comparative-negligence rule then decides what you can collect.
Massachusetts applies modified comparative fault (51% bar). Massachusetts uses modified comparative fault with 51% bar. Authority: Mass. Gen. Laws ch. 231 § 85.
| Claim type | Deadline | Statute | Clock starts |
|---|---|---|---|
| Personal injury (negligence) | 3 years | Mass. Gen. Laws ch. 260 § 2A | Date of injury |
| Medical malpractice | 3 years | Mass. Gen. Laws ch. 260 § 2A | Discovery or treatment end |
| Wrongful death | 3 years | Mass. Gen. Laws ch. 260 § 2A | Date of death |
| Property damage | 3 years | Mass. Gen. Laws ch. 260 § 2A | Date of damage |
Massachusetts is a true no-fault state for car-accident claims. That means PIP coverage pays for medical bills regardless of fault. To sue the at-fault driver beyond PIP, you generally must clear a tort threshold of serious injury defined by Mass. Gen. Laws ch. 90 § 34A.
Massachusetts requires UM coverage at a minimum of 20/40 (Mass. Gen. Laws ch. 175 § 113L). Stacking treatment: limited.
Massachusetts caps non-economic damages in medical-malpractice cases at $500,000. Punitive damages are limited per statute (by statute only). Authority: Mass. Gen. Laws ch. 231 § 60H.
Massachusetts tolls the running of the SOL while the defendant is absent from the state. The defense bears the burden of proving the dates of absence, and tolling typically does not apply to defendants who can be served via long-arm statute or through their Massachusetts insurer.
Insurance negotiations do not toll the statute. Massachusetts courts have repeatedly held that an adjuster's willingness to talk settlement is not a waiver of the SOL defense. Plaintiffs' lawyers routinely file protective complaints in the final 30 days even if talks are ongoing.
No. A workers' compensation claim is a separate administrative remedy with its own deadlines. If a third party (not your employer) caused the injury, you must still file the civil personal-injury suit within the standard Massachusetts SOL.
Tolling pauses the clock. Massachusetts recognizes tolling for minority, mental incapacity, defendant absence, and (in narrow cases) fraudulent concealment of the cause of action by the defendant.
Choice-of-law principles generally apply the SOL of the state where the injury occurred (the lex loci delicti rule), but Massachusetts courts also look at the borrowing statute and the parties' connections. Cross-state cases benefit from early counsel.
Yes, in limited circumstances. Massachusetts permits tolling agreements between the parties that extend the deadline, but they must be in writing, signed by an authorized representative of each side, and entered before the original deadline expires.
No. Only proper filing of a civil complaint in a Massachusetts court stops the SOL. Demand letters, pre-suit mediation, and adjuster negotiations have no legal effect on the statutory deadline.
In most states the personal-injury SOL applies uniformly to negligence-based claims regardless of accident type. Massachusetts does have separate deadlines for medical-malpractice, wrongful-death, and certain intentional-tort claims, addressed on dedicated pages.
