COMPARATIVE NEGLIGENCE
A share of the blame
need not end your case.

As Seen On:
What comparative negligence means for your claim.
After almost any accident, the other side looks for a way to put some of the blame on you. They do it because Massachusetts follows a rule called comparative negligence, and under that rule every percentage of fault assigned to you comes straight out of your recovery. It is one of the most powerful tools an insurer has, and it is used constantly, quietly, and often unfairly, which is why understanding how it works is one of the most important things an injured person can do.
The good news is that being partly at fault does not take away your right to compensation. Massachusetts uses a modified version of the rule, so an injured person can still recover as long as their share of the blame is not greater than the other side’s. What shifts is the size of the recovery, reduced in proportion to your percentage of fault, which means the fight over those percentages is often the real fight in the case. Our Boston personal injury attorney team pushes back hard on inflated blame, because a few points of fault can move a claim by thousands.
This page explains what comparative negligence is, how the Massachusetts rule works, when a share of fault reduces or bars a claim, and how insurers try to use it against you. It is written to inform, and the way the rule applies always depends on the specific facts. If an insurer is trying to pin the blame on you after an accident that was not your fault, a free review can tell you where you really stand at no cost and with no obligation. People are often surprised by how early the blame-shifting starts. It can begin at the scene, in the way a question is asked by a responding officer or an adjuster who calls within days, long before anyone has thought about a lawyer. A friendly voice on the phone is not a neutral one; its job is to gather statements that can later be read as admissions. Knowing that in advance, and knowing that you are under no obligation to give a recorded account or to speculate about what happened, is often what keeps a fair claim from being quietly undermined in its first week.

How Massachusetts law handles shared fault.
The modified comparative negligence rule
Massachusetts follows a modified comparative negligence rule set out in MGL c.231 §85. Under it, an injured person’s own negligence does not bar recovery as long as that negligence was not greater than the combined fault of the parties they are suing. In plain terms, you can recover as long as you were not more than half at fault. Cross that line, to fifty-one percent or more, and the statute bars recovery entirely, which is exactly why insurers work so hard to push a victim’s share of blame over the halfway mark.
How a share of fault reduces a recovery
Below that bar, fault does not erase a claim; it shrinks it. The same statute reduces any award in direct proportion to the injured person’s share of the blame, so a recovery is cut by whatever percentage of fault is assigned to them. That arithmetic is why the percentages matter so much: the difference between being found ten percent and forty percent at fault can change a recovery dramatically, even though the injury is identical. Establishing the real division of fault with hard evidence is the heart of the work.
Fault, evidence, and the deadline
Because fault is decided on the evidence rather than the insurer’s say-so, the police report, the scene, the vehicle or property damage, and the witnesses all carry real weight, and preserving them early is essential. The claim itself must also be brought in time; most Massachusetts injury claims must be filed within three years under MGL c.260 §2A. Letting the evidence fade only makes it easier for the other side to shift more of the blame onto you. It also helps to understand what the percentages are really built from. Fault is not assigned by gut feeling; it is argued from specific facts, the speeds, the distances, the sightlines, the signals, the warnings, and the choices each person had time to make. That is why two cases with similar injuries can be divided very differently, and why a careful reconstruction of the moments before an accident so often shifts the numbers. A share of blame that looks obvious in the insurer’s first letter frequently shrinks once the full sequence of events is laid out with evidence behind it.
Where comparative negligence comes up in a claim.
The crashes where fault is split
Comparative negligence is fought hardest in motor-vehicle cases, where a collision almost always leaves room to argue that both drivers did something wrong. The insurer’s script is familiar: the injured driver was speeding, following too closely, or could have avoided it, and every point it pins on the victim is a point off its own bill. Those disputes run through the daily work behind our Boston car accident lawyer and Boston truck accident lawyer cases, where a few percentage points can swing a serious claim, and the reflex is sharper still against riders, who are routinely blamed for crashes drivers cause, a fight a Boston motorcycle accident lawyer knows well.
The same tactic off the road
Away from traffic the argument only changes costume. A person crossing the street is told they darted out or ignored the signal, a fall becomes a failure to watch your step, and a dog bite becomes a claim that the animal was provoked, so a Boston pedestrian accident lawyer, a Boston slip and fall lawyer, and a Boston dog bite lawyer all answer the same blame-shifting a driver’s insurer uses. Whatever the setting, the response is the same: the record of what actually happened, not the version most convenient to the other side.
Why the percentage is the whole fight
What ties every one of these cases together is the arithmetic beneath them. Because each percentage point of fault assigned to the injured person reduces the recovery dollar for dollar, and because crossing the halfway line erases it altogether, a case with an undisputed injury can still turn completely on the numbers. That is why a blame-shifting argument is met with evidence rather than indignation, and why the real division of fault is worked out from the facts, the speeds, the sightlines, the signals, and the choices each person had time to make, long before it is ever argued to a jury. An insurer that cannot seriously dispute how badly someone was hurt will spend its energy trying to move responsibility onto the victim instead, because under this rule that is the cheapest way to reduce what it owes.
How a share of fault gets decided
Comparative negligence turns an injury claim into a question of proportions, and a full claim breaks that question into its moving parts. There is the raw percentage of fault, the share of responsibility a jury or an adjuster assigns to each party, which is rarely obvious and almost always contested. There is the fifty-percent bar, the line past which a victim recovers nothing at all, which gives the insurer a powerful incentive to push a share of blame as high as it can. There is the reduced recovery below that line, where the award is trimmed by the victim’s percentage, so a strong injury can still be undercut by a weak fault story.
And there is the insurer’s blame-shifting itself, the routine, expected effort to move responsibility onto the injured person through leading questions, selective facts, and assumptions dressed up as findings. The categories below are a starting point rather than a limit, and most disputed claims involve several at once, which is why the division of fault is proven with real evidence rather than conceded to whoever argues it most confidently.
There is one more thing worth understanding about how this plays out. Because the fifty-percent bar is so consequential, insurers will sometimes make an early offer that quietly assumes a large share of fault on the victim’s part, hoping the number is accepted before anyone examines whether that share is fair. A settlement built on an inflated fault percentage looks reasonable only until the real division of blame is worked out. Testing that percentage against the actual evidence, rather than taking it as given, is often the single most valuable thing done in a disputed claim, and it is exactly the work an insurer is counting on a victim not to do.
In the end, comparative negligence rewards the side that comes prepared with proof, and quietly punishes the one that arrives with only its version of events. That is precisely why a claim clouded by a fault dispute should never be conceded, or settled, on the insurer’s say-so alone, and why the number that finally matters is the one the evidence, once it is fully tested, actually supports.

How a blame dispute is answered
Lock down the accident evidence now
Photograph the scene, the vehicles or the hazard, and the conditions, and get the names of any witnesses, because in a fault dispute the evidence of what really happened is what decides who is blamed.
Say little to the other insurer now
Be careful what you say to the other side's insurer, because an offhand apology or a guess about the crash can be turned into an admission of fault that raises your percentage and lowers the recovery.
Let a lawyer prove the actual fault
Before you accept the insurer's version of that blame, let a lawyer prove the real division of fault, because a few points shifted the right way can be the difference between a full recovery and none.

Personal injury law in Boston answered directly.
Do I have a personal injury claim?
You may, if someone else’s carelessness caused your injury. The key questions are whether another person or company was negligent, whether that negligence caused your injury, and how serious the harm is. Many people are unsure whether their situation rises to a claim, especially when an insurer downplays it. A free review with an attorney is the best way to find out, because we can look at the facts, the evidence, and the insurance and tell you honestly whether you have a case and what it may be worth, at no cost to you.
What kinds of cases do you handle?
We handle the full range of serious injury and wrongful death cases, including car, truck, motorcycle, bus, rideshare, bicycle, and pedestrian crashes, slip and fall and other premises injuries, dog bites and animal attacks, injuries from dangerous or defective products, and fatal accidents. What these cases share is that someone was hurt by conduct that should not have happened. If you are not sure whether your situation fits, the simplest thing is to ask; the review is free, and we will tell you honestly whether we can help.
How much is my claim worth?
It depends on the severity of the injuries and their lasting effects. Value can reflect past and future medical care, lost wages and reduced earning capacity, pain and suffering, and the long-term impact of a serious or permanent injury, along with property damage in a crash. Every case is different, and the future care is often the largest part of a serious claim. Be cautious of anyone who promises a number up front; a careful attorney evaluates the claim only after reviewing how the injury happened and the full medical picture.
What if the insurer says I was partly at fault?
You can still recover as long as you were not more than half to blame. Under comparative negligence, MGL Chapter 231 Section 85, your compensation is reduced by your share of fault but not eliminated unless that share passes fifty percent. Insurers often exaggerate the injured person’s role to cut what they pay, sometimes based on little evidence. An attorney can present the full picture of how the injury happened and protect your recovery from an unfair or inflated fault argument.
Should I talk to the insurance company?
It is best to be cautious. The other side’s insurer, and sometimes even your own, may contact you quickly and sound friendly, but their goal is to limit what they pay, and an early recorded statement can be used against you while you are still hurting. You are not required to give one. An attorney can deal with the insurers for you, so you do not say something that is later taken out of context, and so the focus stays on the other side’s fault and your recovery rather than on the insurer’s bottom line.
How long do I have to file a claim?
Most injury claims must be filed within three years under MGL Chapter 260 Section 2A, and for an injured child the deadline is paused under MGL Chapter 260 Section 7. Claims involving a city or other public entity can carry much shorter notice deadlines. Because evidence fades and cameras record over their footage within days, it is best to act soon so the proof can be preserved well before any deadline approaches.
What if I cannot afford a lawyer?
You can. Larson Law handles injury claims on a contingency fee, which means there is no charge unless we recover money for you, and the first review is always free. We advance the costs of investigating the claim and working with any experts the case needs. You do not pay out of pocket while you recover, and we are only paid from a successful result. That arrangement exists so that anyone, regardless of their finances, can afford strong legal help after a serious injury.
Do I really need an attorney for my claim?
For a minor injury you may not, but for any serious injury an attorney usually makes a real difference. Insurers settle for less when no lawyer is involved, and the rules around fault, deadlines, and coverage are easy to get wrong on your own. An attorney levels the field, handles the insurers, proves the claim, and pursues the full value while you focus on recovering. Because the first review is free and we work on a contingency fee, there is no cost to find out whether you need one and what your claim may be worth.
How long will my case take?
It depends on the case. Some claims resolve in a matter of months through negotiation, while others, especially serious injuries that are still healing or cases an insurer refuses to value fairly, take longer and may require filing suit. It is usually wise not to settle until the full extent of your injuries is known, since you generally cannot reopen a claim later. An attorney can give you a realistic timeline for your situation and work to move the case as efficiently as possible without leaving money on the table.
What if a loved one died from an injury?
If an injury proved fatal, close family may bring a wrongful death claim under MGL Chapter 229. Such a claim can seek compensation for the loss of the person’s income, services, companionship, and guidance, along with funeral and related expenses. These cases are painful and the legal steps are complex, and an attorney can handle the investigation and the filings so the family can focus on each other, never paying anything up front and owing a fee only if there is a recovery.
How much does a personal injury attorney cost?
Nothing upfront. Larson Law handles personal injury claims on a contingency fee, so there is no charge unless we recover money for you, and the first review is always free. We advance the costs of investigating the claim, obtaining the records, and working with experts. We are only paid from a successful result, which lets an injured person take on the insurers without paying out of pocket while they recover, so cost is never a reason to wait to find out what your claim may be worth.
What should I do after an accident?
Get medical care right away, even if you feel okay, since some injuries appear hours or days later, and keep every record. Write down how it happened, photograph the scene, the cause, and your injuries, and get the names of any witnesses while it is fresh. Report the accident as appropriate. Avoid giving the insurer a recorded statement or signing anything before you have spoken with an attorney, who can preserve the evidence and protect both your health and your claim from the start.
