Dismissal, almost without exception
If a personal injury lawsuit is filed in Massachusetts after the applicable statute of limitations has run — the general three-year deadline under M.G.L. c. 260, § 2A, or the seven-year outer limit for medical malpractice — the court will almost always dismiss the case as time-barred. This happens regardless of how strong the underlying claim actually is or how serious the injury turned out to be.
Courts apply these deadlines strictly
Statutes of limitations exist specifically to create a firm, predictable cutoff, and Massachusetts courts generally enforce them that way. Being close to the deadline, or having a sympathetic reason for the delay that doesn't fit a recognized legal exception, isn't on its own a basis for a court to excuse a late filing.
A distinctive, second risk: missing presentment
For any claim against a government entity, Massachusetts courts have shown they will dismiss a case over a presentment letter that arrived even a few days late — regardless of whether the general three-year statute of limitations has run at all. See our full guide to the presentment requirement for exactly how strictly this gets enforced, and why mailing a letter on time isn't the same as it being received on time.
Negotiations end along with the legal leverage behind them
One of the more painful practical consequences: once the statute of limitations has actually run, an insurance company has no legal obligation to keep negotiating, to make any offer, or to pay anything at all — even if settlement talks were active and seemingly productive right up until the deadline passed.
If there's any doubt at all
Because the consequence of missing a deadline is generally permanent, and because Massachusetts's rules genuinely differ depending on the type of claim and whether a government entity is involved, the only reliable way to know where things actually stand is to confirm the exact date with a licensed Massachusetts attorney as early as possible.
