When someone you love is killed and the other side starts hinting that your loved one was partly to blame, it can feel like a second injury. You are grieving, and now a claims adjuster or a defense lawyer is quietly building a story that puts some of the fault on the person who died. Families ask us a version of the same question all the time: if he was speeding a little, or she stepped off the curb against the light, is the case just over? The honest answer is no, not usually. Massachusetts law expects juries to sort out shared fault, and a share of blame on the person who died does not automatically end a claim.
Massachusetts uses modified comparative negligence
The rule that governs shared fault here is the comparative negligence rule Massachusetts courts apply under M.G.L. c. 231, § 85. It is a “modified” comparative system, and the modification matters. Under a pure comparative rule, a person who was mostly at fault could still recover a sliver. Massachusetts does not go that far. Instead, the statute lets a family recover as long as the person who died was not more at fault than the people they are suing. Fall on the wrong side of that line and the claim recovers nothing. Stay on the right side of it and the claim survives, with the recovery reduced by the deceased person’s share.
So partial fault is not a wall. It is a dial. The whole fight in a wrongful death partial fault case is over where that dial gets set.
How a jury actually splits the fault
Juries do not decide fault with a gut feeling that someone was “kind of” responsible. They assign numbers. At the end of a trial the jury is asked to put a percentage of fault on each party whose conduct is in question: the defendant, sometimes more than one defendant, and the person who died. Those percentages have to add up to 100.
Say a jury looks at a crash and decides the at-fault driver was 80 percent responsible and the person who died was 20 percent responsible for not wearing a seatbelt or for crossing mid-block. The family still recovers. The recovery is simply reduced by that 20 percent. The estate does not walk away with nothing; it walks away with a figure the jury already discounted to account for the deceased person’s share. That is the machinery, and it runs the same way whether the case settles or goes to verdict, because both sides are always predicting what a jury would do.
The 51 percent line, and why it is everything
Here is the part that changes strategy on both sides. If the jury decides the person who died was more at fault than the defendants combined, the family recovers nothing at all. Not a reduced amount. Nothing. In practical terms people call this the 51 percent bar, because once the deceased person’s share tips over half, the claim is defeated.
The exact wording of the statute is a little kinder than “51 percent” suggests. Recovery is barred only when the deceased person’s negligence is greater than the total negligence of the defendants. A dead-even split, 50 percent against 50 percent, still lets the family recover, reduced by half. The bar snaps shut only when the deceased person’s share climbs past the defendants’ share. But you can see why that single line dominates everything. Everything below it is a reduction. One point above it is a total loss.
Why the defense pushes so hard on your loved one’s fault
Once you understand the line, the defense playbook is obvious. The insurer has two ways to pay less. It can shrink the value of the case, or it can move fault onto the person who died. Moving fault does both at once. Every percentage point they can pin on your loved one is a percentage point off any recovery, and if they can shove the number past half, they owe nothing.
So expect it. Expect the argument that your loved one was speeding, distracted, jaywalking, not wearing a seatbelt, ignoring a warning, or somewhere they should not have been. Sometimes there is a kernel of truth in it. Often it is inflated well past what the evidence supports, because the defense knows that a sympathetic argument about the deceased person’s carelessness is worth real money to them. A good part of a wrongful death claim is refusing to let that number drift upward unchallenged.
- They read the police report for any line that hints your loved one contributed, and they build on it.
- They hire reconstruction experts to argue your loved one had time to avoid the crash.
- They point to seatbelt use, phone records, or a blood test to suggest the outcome was partly self-inflicted.
- They frame ordinary human behavior as recklessness so the percentage climbs.
Evidence decides the percentage, and evidence disappears fast
Fault percentages are not handed down from on high. They are argued from evidence, and the side with better evidence usually wins the number. That is why what happens in the first days after a death can quietly decide the whole case months or years later.
The problem is that the proof of what really happened starts vanishing almost immediately. Skid marks fade. Vehicles get repaired or scrapped. A commercial truck’s electronic data can be overwritten on its normal cycle if no one demands it be preserved. Surveillance footage from a nearby business is often taped over within days. Witnesses who saw the whole thing move, forget details, or stop returning calls. Every one of those is a fact that could hold the defense’s fault number down, and every one of them has a short shelf life.
What protects a family against an unfair fault split
- The scene. Photographs of the roadway, the vehicles, the sightlines, and the conditions, taken before anything is cleaned up or repaired.
- Vehicle and device data. Event data recorders, telematics, and phone records that show speed, braking, and what each driver was actually doing.
- Witnesses. Statements taken while memories are fresh, from people who have no stake in the outcome.
- The official record. The police or agency report, along with any body-camera or dashcam footage, requested before it is purged.
An early letter demanding that a defendant preserve its data and its vehicle is one of the most useful things a lawyer can send. Once that evidence is locked down, the defense loses the freedom to invent a version of events that no one can contradict. This is also why waiting hurts you. The deadline to file a wrongful death claim in Massachusetts is a hard cutoff, but the practical clock on evidence runs out long before the legal one does.
What partial fault means for what your family can recover
Comparative negligence changes the size of a recovery; it does not change what the law lets you claim. The categories of loss a Massachusetts wrongful death claim covers stay the same whether the deceased person bears zero fault or thirty percent. The percentage just applies at the end, as a discount. You can read more about those categories on our page covering wrongful death damages in Massachusetts, and about how the case moves from filing to resolution in our overview of the wrongful death claim process.
Be skeptical of anyone, on either side, who quotes you a number early. There is no meaningful average for these cases. Value is built from the specific facts, the records, and where the fault line lands, and the fault line is exactly the thing that is still being fought over when someone tries to hand you a figure.
Questions families ask
My loved one was partly at fault. Is the case automatically over?
No. Under Massachusetts law a claim survives as long as the person who died was not more at fault than the people responsible. If their share is 50 percent or less, the family can still recover, reduced by that share. The claim is defeated only if their fault is found to be greater than the defendants’ combined fault.
Who decides the fault percentages?
A jury does, at trial, by assigning each party a percentage that adds up to 100. Because both sides predict what a jury would do, those same percentages drive settlement negotiations long before any trial. That is why the evidence behind the percentage matters so much.
What is the 51 percent bar?
It is the point where shared fault stops being a discount and becomes a total loss. If the person who died is found more at fault than the defendants, the claim recovers nothing. One point can be the difference between a reduced recovery and no recovery, which is why the defense works so hard to inflate your loved one’s share.
How do I keep the defense from exaggerating my loved one’s fault?
Preserve evidence early and get a lawyer involved fast. Scene photos, vehicle and phone data, witness statements, and official reports are what hold the fault number down, and much of it disappears within days if no one moves to protect it.
Does partial fault change what we can claim?
No. The categories of loss are the same. Comparative negligence only reduces the final recovery by the deceased person’s percentage of fault; it does not remove any category of damages a family is otherwise allowed to pursue.
