How Long Do You Have to File a Personal Injury Claim in Massachusetts?

Personal injury claims in Massachusetts are subject to a strict legal deadline known as the statute of limitations. Once this window closes, the injured party generally loses the right to pursue compensation through the courts, regardless of the merits of the case. Understanding this timeline is essential for anyone considering legal action after an accident.

This post outlines how long individuals have to file a personal injury claim in Massachusetts, along with several important exceptions that can affect the deadline. Being aware of these rules early on can help protect one's legal options going forward.

The General Massachusetts Personal Injury Deadline: Three Years

The three-year statute of limitations under M.G.L. c. 260, § 2A applies to most personal injury claims, including car accidents, slip and fall injuries, dog bites, construction accidents, and premises liability cases. The clock typically starts on the date of the accident or injury. If you file one day after that window closes, the court will almost certainly dismiss your case regardless of the strength of the evidence.

Three years may sound generous, but injury claims require time to investigate, gather medical records, retain experts, and negotiate with insurers. Attorneys who handle serious injury cases routinely begin building a file within days of the accident, not months later.

When the Clock Starts: The Discovery Rule

In some cases, injuries are not apparent right away. Massachusetts courts apply a discovery rule that starts the limitations clock when the plaintiff knew or reasonably should have known of the injury and its likely cause.

While this issue arises most in medical malpractice and toxic exposure cases, it can apply to any personal injury claim where the harm or its cause was not reasonably apparent at the time of the incident; for example, a slow-developing injury from a workplace accident or a construction defect.

For most accident cases, such as a car crash on Route 3A in Quincy or a fall on a Brockton sidewalk, the injury is obvious immediately, and the clock starts on the date of the event. Do not assume the discovery rule extends your deadline without speaking to an attorney, because courts apply it narrowly.

Exceptions That Shorten or Extend the Massachusetts Deadline

Several circumstances change the standard three-year window. Knowing which rules apply to your situation can be the difference between a viable claim and a barred one.

• Claims against government entities: If a city, town, or the Commonwealth caused your injury, Massachusetts requires you to present a claim to the appropriate government entity within two years under M.G.L. c. 258. Missing this step bars the lawsuit even if the three-year period hasn't expired. Additional procedural rules govern when a suit can be filed after presentment, so these claims should be handled with legal guidance as early as possible.

• Medical malpractice: The deadline is three years from discovery, with an absolute seven-year statute of repose under M.G.L. c. 260, § 4. Claims involving a foreign object left in the body are not subject to the repose period.

• Wrongful death: Under M.G.L. c. 229, § 2, a wrongful death claim generally must be filed within three years of the date of death. However, the deadline can shift in cases involving latent injuries or malpractice-caused deaths, where the underlying wrongful act's own discovery date may affect the calculation. Because these interactions can be complex, families should not assume a fixed three-year-from-death deadline without confirming it applies to their specific circumstances.

• Minor victims: If the injured person was under 18 at the time of the accident, the statute of limitations is tolled until the child turns 18 under M.G.L. c. 260, § 7. The three-year period then begins on the 18th birthday.

Why Waiting Hurts Your Claim Even Before the Deadline

The statute of limitations is an absolute cutoff, but evidence problems arise well before it. Surveillance footage is typically overwritten within 30 to 90 days. Witnesses forget details or become difficult to locate. Accident scenes change. Medical records become harder to connect to the incident if treatment is delayed. The sooner you contact an attorney, the more complete and credible your evidence file will be.

Frequently Asked Questions: Massachusetts Personal Injury Deadlines

How long do I have to file a personal injury claim in Massachusetts?

Most claims must be filed within three years of the injury date under M.G.L. c. 260, § 2A. Several exceptions apply depending on the type of claim and who caused the harm.

Does the clock start on the date of the accident or the date I was diagnosed?

For most accidents, it starts on the date of injury. For latent conditions, courts apply a discovery rule that starts the clock when you knew or should have known of the injury and its cause.

What happens if I miss the Massachusetts statute of limitations?

The court will almost certainly dismiss your lawsuit. Missing the deadline eliminates your right to sue regardless of how clear the other party's fault was.

Is the deadline shorter for claims against a city or town in Massachusetts?

Yes. You must first present a claim to the government entity within two years under M.G.L. c. 258 before filing suit. Missing that presentment deadline also bars the claim.
