How to File a Personal Injury Claim in Massachusetts

If you’ve just been hurt in an accident, filing a personal injury claim can feel like one more thing piled on top of everything else: the pain, the missed work, the medical bills stacking up. We’ve guided plenty of Massachusetts families through this exact process, and here’s the truth: it’s rarely as complicated as it looks from where you’re standing right now. Most people aren’t overwhelmed by the claim itself. They’re overwhelmed by everything else happening at once.

Here’s the quick version of what you need to know before you file.

The Quick Version

• A claim isn’t the same as a lawsuit. Filing a claim usually means notifying an insurance company and negotiating toward a settlement. A lawsuit is a separate legal action, and most personal injury cases in Massachusetts get resolved before anyone sets foot in a courtroom.
• You generally have three years. Massachusetts law gives you three years from the date of your injury to file a personal injury claim in court. Some situations change that window; more on that below.
• Yes, Massachusetts law requires Personal Injury Protection (PIP). Every driver carries it, and it’s meant to cover medical bills and lost wages after a car accident, regardless of who caused it.
• You don’t need a lawyer to file a claim, but it can help. Insurance claims come with paperwork, deadlines, and negotiating tactics that are easy to get wrong while you’re also trying to recover. A free consultation can help you understand your options either way.

What Is a Personal Injury Claim?

A personal injury claim is your request for compensation after someone else’s negligence caused you harm. Most of the time, that means working with another party’s insurance, but not going straight to the court. You, or an attorney representing you, notify the responsible party’s insurance company, lay out what happened and what it’s cost you, and negotiate toward a settlement.

A lawsuit is different. That’s a formal legal case filed in court, and it typically only comes into play when an insurance company won’t offer a fair settlement on its own. We’ll get into that later. For now, know this: most personal injury claims in Massachusetts get resolved without anyone setting foot in a courtroom.

Claims can come from a lot of different situations. Car, truck, and motorcycle accidents are the ones we see most often, but slip-and-falls, dog bites, and medical malpractice can lead to a claim too. The details change with the type of accident, but the idea stays the same. Someone else’s carelessness caused you harm, and the law may allow you to seek compensation for it.

Is PIP Required in Massachusetts?

Massachusetts is a no-fault state, and every driver here is required to carry Personal Injury Protection, or PIP, under M.G.L. c. 90, §34M. It’s built into your auto policy whether you’ve thought about it or not.

How No-Fault (PIP) Coverage Actually Works

PIP covers your medical bills and a portion of your lost wages after a car accident, and it pays out regardless of who caused the crash. That’s the “no-fault” part. You file this claim with your own insurance carrier, not the other driver’s, and it doesn’t matter who was at fault.

Here’s where people get tripped up. PIP only applies to injuries. It doesn’t cover damage to your car. Vehicle damage is still a fault-based claim, which means someone, usually the at-fault driver’s insurer, has to be found responsible before it gets paid.

PIP vs. a Bodily-Injury Liability Claim

PIP and a bodily-injury claim against the at-fault driver are two different things, filed with two different insurers, and often handled by two different adjusters. PIP pays first, up to its limit, regardless of fault.

If your injuries meet the threshold under M.G.L. c. 231, §6D, you may also be able to pursue a separate claim against the at-fault driver for pain and suffering and costs PIP didn’t cover. That claim runs on its own track. Settling one doesn’t automatically settle the other, and we’ve seen that gap catch people off guard; one claim gets closed out while the other sits open because nobody flagged it clearly.

How Long Do You Have to File a Claim? Or Statute of Limitations on Personal Injury

In Massachusetts, you generally have three years from the date of your injury to file a personal injury lawsuit, under M.G.L. c. 260, §2A. That’s the number most people hear, and for a lot of cases, it’s the right one.

But “generally” is doing some work in that sentence.

Exceptions That Can Shorten or Change the Deadline

If your claim involves a city, town, state agency, or an entity like the MBTA, the clock moves faster. Under M.G.L. c. 258, §4, you have to present a written claim to the public employer within two years of your injury, not three, or you can lose your right to pursue it, even though the general three-year window hasn’t closed yet.

When the clock starts, it can shift too. In cases where an injury isn’t obvious right away, Massachusetts courts have applied what’s known as the discovery rule (under Franklin v. Albert, 1980 case), meaning the clock can start when you knew, or reasonably should have known, that you were injured and what caused it, not necessarily the date of the incident itself.

Special Rules for Minors or Persons with Mental Illness

If the injured person is a minor, the countdown works differently. Under M.G.L. c. 260, §7, the statute of limitations generally doesn’t start running until they turn 18, or have mental illness, which in practice can extend the filing window well past three years from the date of the injury.

None of this is a substitute for checking your specific situation. Deadlines like these are exactly the kind of detail that’s easy to get wrong on your own, and getting it wrong can end a valid claim before it ever starts.

Once you know you’re within your window, the next question is practical: what should you actually be doing right now, before you file anything at all?

What to Do Before You File

A few things you do in the first days after an accident end up shaping your entire claim. None of them are complicated, but they’re easy to skip when you’re hurt and overwhelmed.

1. Get Medical Care and Documentation
   See a doctor, even if you think you’re fine. Adrenaline hides pain, and some injuries, like whiplash or concussions, don’t show symptoms right away. Beyond your health, this creates the medical record your claim depends on. Insurers weigh treatment gaps heavily, and an injury with no documentation is hard for anyone to evaluate, including us.
2. Report the Incident
   If you’re in a car accident involving injury, death, or more than $1,000 in property damage, Massachusetts law requires a written report within five days, under M.G.L. c. 90, §26. Beyond the legal requirement, that report becomes the reference point insurers use to piece together what happened. For a slip-and-fall or other injury, report it to the property owner or manager on the spot if you can, and ask for it in writing.
3. Gather and Preserve Evidence
   Evidence has a way of disappearing. Take photos of the scene, your injuries, and anything that caused the accident. Get names and contact information for witnesses while they’re still there. If there’s traffic camera, dashcam, or surveillance footage nearby, note it, since a lot of that footage gets overwritten within days or weeks.
4. Understand What Documents Your Claim Will Need
   Beyond the police or incident report, expect your claim to need your medical records and bills, proof of lost income, such as pay stubs or a wage verification form from your employer, and any correspondence with insurance adjusters. Insurers can be particular about the format they want this in, so keeping things organized as you go saves a lot of back-and-forth later.

Once you’ve got your care underway and your documentation started, you’re ready for the part most people actually mean when they ask how to file a claim.

Filing the Claim: Step by Step

Here’s what actually happens, in order, once you’re ready to file. It’s more of a process than a single action, and each step feeds into the next.

Filing Your PIP Claim

This is the claim you open first, with your own insurer, regardless of who caused the accident.

Step 1: Notify Your Insurer

Massachusetts auto policies require notice “as soon as practicable.” Since PIP is no-fault, this claim opens before anyone determines who caused the accident, so there’s no reason to wait.

Step 2: Submit Your PIP Application and Documentation

Your insurer will send a PIP application. Along with it, expect to submit medical bills and records, and wage documentation if you’re claiming lost income- the paperwork we covered in the last section. Having it organized before an adjuster asks for it saves you a lot of back-and-forth.

Filing a Claim Against the At-Fault Driver

This is a separate claim, filed with the at-fault driver’s insurer, and it only comes into play if your injuries clear a specific legal threshold.

Step 3: Find Out If Your Injury Clears the Tort Threshold

Under M.G.L. c. 231, §6D, you generally need your reasonable and necessary medical expenses to exceed $2,000, unless your injury falls into one of these categories, which qualify regardless of the medical bill amount:

Qualifies Without the $2,000 Threshold

• A broken bone, including minor fractures
• Serious and permanent disfigurement
• Loss of a body member, or permanent loss of its use
• Loss of sight or hearing
• Death

If you clear the threshold, Massachusetts law may allow you to pursue the at-fault driver for pain and suffering and costs your PIP coverage didn’t reach.

Step 4: Keep Treating and Documenting

This runs in the background through everything that follows. Insurers weigh your full course of treatment, not just the first visit, so this step feeds both your PIP claim and any claim against the at-fault driver.

Step 5: Send a Demand Package to the At-Fault Insurer

Once treatment has progressed enough to show the real scope of the injury, a demand package goes out, laying out how the accident happened, the injuries and treatment involved, the financial losses, and the amount being sought. Massachusetts law holds insurers to standards here too. Under law, an insurer is expected to acknowledge claims promptly, investigate them fairly, and not deny a claim without a reasonable basis.

Step 6: Negotiate

The insurer typically responds with a counteroffer or a request for more documentation, sometimes including an independent medical exam. Back-and-forth is normal, and it can take time, especially if there’s disagreement over the value of your damages.

Step 7: Resolve the Claim, or Take the Next Step

Most claims end with a signed settlement. If an insurer isn’t negotiating in good faith, Massachusetts consumer protection law offers another lever: a Chapter 93A demand letter, which gives the insurer 30 days to respond with a reasonable offer before further legal action becomes an option. If a fair resolution still isn’t reached, that’s when a claim can become a lawsuit, which we’ll cover later in this article.

A lawsuit is one path forward, but it’s not the only thing to think through before you settle anything. There’s a simpler mistake that trips up even straightforward claims, and it happens well before any lawsuit ever comes up.

Handling Property Damage and Injury Claims Separately

Your car and your body are two different claims, and it’s worth treating them that way. Insurers sometimes bundle them into a single release, especially early on, and once you sign it, you may have given up your right to pursue the other.

This trips people up more than you’d expect. A property damage settlement usually moves fast, since a damaged vehicle is straightforward to value. An injury claim takes longer, especially if you’re still treating. If you sign a release before your treatment is finished because the property offer looked reasonable, that release may cover injuries you haven’t fully diagnosed yet.

Read anything you’re asked to sign carefully, and check exactly what it releases. If it’s not clear whether it covers your injury claim, your property claim, or both, ask before you sign.

Before any of that, though, there’s a question almost everyone in this situation asks: what if the accident wasn’t entirely the other person’s fault? Are you then able to claim your damages?

Can You Claim if You Were Partly at Fault?

Often, yes. A lot of people assume any share of blame ends their claim, and that’s not how Massachusetts law works.

Our state legal system is based on a modified comparative negligence rule, which means you can still recover damages as long as your share of fault isn’t greater than the other party’s. If you’re found more than 50% at fault, the law bars recovery. Below that line, your compensation gets reduced by your percentage of fault.

Say you’re rear-ended but were also found to be driving with a broken taillight that contributed to the crash. If you’re assigned 20% of the fault, your damages get reduced by that 20%, not wiped out entirely.

Fault isn’t just declared, either. It gets worked out through the police report, witness statements, photos, and the insurers’ own investigations, which is exactly why the evidence you gather early carries so much weight later. If liability is contested, that’s often where having someone negotiate on your behalf makes the most difference.

Fault isn’t the only thing that can complicate a claim, though. Money does too, and a lot of people hesitate to even start because they’re not sure what pursuing a claim is going to cost them.

How Much Does It Cost to File a Claim or Lawsuit?

Filing a claim yourself has no upfront cost. If you work with a personal injury attorney, most, including us, handle these cases on contingency, meaning there’s no fee unless we win, and fees are only charged if you recover. Clients may still be responsible for certain litigation costs and expenses regardless of outcome, so it’s worth asking upfront how that’s handled. Court filing fees apply if a case becomes a lawsuit, and they vary by court, but they’re a small part of the overall picture compared to what’s at stake in your claim.

Do You Need a Personal Injury Lawyer, or Can You File a Claim Yourself?

You can file a claim yourself. Nothing about the process legally requires a lawyer, and plenty of straightforward claims get filed and settled without one.

That said, look back at where this article kept circling. Two separate claims that are easy to confuse. Deadlines with real exceptions. Wage documentation that’s hard to pull together. Release language that can waive more than you intended. Fault disputes that hinge on evidence gathered in the first few days. None of that is impossible to handle alone. It’s just where things commonly go sideways, usually without anyone realizing it until later, when it’s harder to fix.

An attorney doesn’t change the facts of your accident. What changes is who’s chasing the paperwork, tracking the deadlines, and pushing back when an offer doesn’t reflect the full picture. If you’re not sure whether your situation is simple or not, that’s exactly what a free consultation is for. There’s no obligation, and no cost to find out where you stand.

We’ve spent years guiding Massachusetts clients, from our offices in Boston, Natick, Fall River, Peabody, Plymouth, and Norwood, through exactly what we’ve just covered in this article: separating a PIP claim from a liability claim, tracking deadlines that don’t forgive a missed date, gathering the documentation insurers ask for, and negotiating when an offer comes in low.

If you’ve been hurt and you’re not sure what to do next, give us a call. A free, no-obligation consultation is the fastest way to find out where things stand.
