File a Personal Injury Claim in Massachusetts

You were hurt because of someone else’s negligence. Maybe it was a car accident, a slip and fall, a dog bite, or an injury at work. You are dealing with medical appointments, missed time from your job, and the stress of not knowing what comes next. Filing a lawsuit may be the last thing on your mind right now — but waiting too long to act is one of the most common and most costly mistakes injury victims make in Massachusetts.

Every personal injury case in Massachusetts has a legal deadline attached to it. Miss that deadline, and you could permanently lose your right to seek compensation — regardless of how strong your case is and regardless of how serious your injuries are. A judge will not consider the merits of your claim if it is filed too late. It will simply be dismissed.

Here is what you need to know about Massachusetts personal injury deadlines, the exceptions that can change your timeline, and why acting sooner rather than later always works in your favor.

The General Rule: Three Years From the Date of Injury

Under Massachusetts General Laws Chapter 260, Section 2A, the statute of limitations — the legal deadline for filing a personal injury lawsuit — is three years from the date the injury occurred. This applies to the most common types of personal injury cases, including car accidents, slip and fall injuries, dog bites, and general negligence claims.

The clock starts on the day you are injured. If you were hurt in a car accident on May 1, 2023, you generally have until May 1, 2026 to file your lawsuit. If you miss that date, the court will almost certainly dismiss your case — no matter how clear the other party’s fault may be, and no matter how significant your injuries are.

Three years sounds like plenty of time. But personal injury cases require investigation, evidence gathering, expert opinions, medical documentation, and careful legal preparation. The attorneys and insurance companies on the other side are not waiting around, and neither should you.

Important Exceptions That Can Change Your Deadline

Massachusetts law recognizes that a strict three-year rule does not fit every situation. In certain circumstances, the clock may start later or be paused entirely. These are called “tolling” exceptions.

The Discovery Rule. Some injuries are not immediately apparent. If you did not know — and could not reasonably have known — that you were injured at the time of the incident, the three-year clock may not start until the date you discovered the injury. This rule most commonly applies in medical malpractice cases, where a surgical error or misdiagnosis may not become apparent until months or years later. It can also apply in cases involving toxic exposure or other delayed-onset conditions.

Minors. If the injured person was under 18 years old at the time of the accident, the statute of limitations is paused until their 18th birthday. They then have three years from that date — meaning until they turn 21 — to file a claim. This protection exists because minors cannot assert their own legal rights.

Mental incapacity. If the injured person was legally incapacitated by a mental illness or disability at the time of the injury, the three-year period may be paused until they regain the legal capacity to make decisions.

Defendant out of state. If the person who caused your injury leaves Massachusetts after the accident but before you file your claim, the time they spend outside the state generally does not count toward your three-year window. This prevents defendants from evading legal responsibility simply by relocating.

Fraudulent concealment. If the at-fault party actively concealed evidence or their own liability — preventing you from discovering your right to file — the statute of limitations may not begin until you become aware of the wrongdoing.

Special Rules for Claims Against the Government

If your injury was caused by a government employee or a government agency — a city worker, a public school, a municipal vehicle, or a state-owned property — different rules apply. Under the Massachusetts Tort Claims Act, you generally cannot file a lawsuit directly in court as your first step. Instead, you must file a formal written claim — called a “presentment” — with the appropriate government agency within two years of the injury.

If you are injured on a public sidewalk or street, you may also need to provide written notice to the city or town within 30 days. Missing this notice requirement can bar your claim entirely, even if you are well within the general three-year window.

Government claims are among the most time-sensitive personal injury situations in Massachusetts. If a government entity may be involved in your case, contact an attorney immediately.

Why Waiting Is Always a Risk — Even Within the Deadline

Even if you are well within the three-year window, waiting has real consequences for the strength of your case.

Evidence disappears. Surveillance footage gets overwritten within days. Physical conditions at accident scenes get repaired or changed. Witnesses move away, forget details, or become difficult to locate. The longer you wait, the harder it becomes to build a compelling case.

Insurance companies also know the deadline and use it strategically. The closer you get to the filing deadline without legal representation, the more leverage they have. They may delay, lowball, or pressure you into accepting a settlement that does not reflect the true value of your injuries.

Getting an attorney involved early — even if you are not sure yet whether you want to file a lawsuit — preserves your options and protects your position.

What Compensation Can You Recover

If your personal injury claim is successful in Massachusetts, you may be able to recover compensation for medical expenses — both past and future — lost wages, reduced earning capacity, pain and suffering, and loss of enjoyment of life. In cases involving severe or permanent injuries, the amounts involved can be substantial.

Massachusetts follows a modified comparative negligence rule, which means you can still recover damages even if you were partially at fault for the accident — as long as your share of fault does not exceed 50%. Your total compensation would be reduced by your percentage of fault.
