Comparative Fault in Michigan: How Partial Fault Affects Your Personal Injury Case

The insurance adjuster on the phone has a theory. You ran the yellow light. You were checking your mirror when the other driver turned left in front of you. You should have seen the spilled coffee before you stepped in it. Whatever the accident was, the adjuster wants you to know it was at least partly your fault — and that’s their justification for offering a fraction of what your case is worth.

Here’s what they’re not telling you. Michigan law does not bar you from recovering damages just because you share some of the blame. Under our comparative fault statute, you can be 10%, 25%, even 50% at fault and still walk away with meaningful compensation. The rules shift at the 51% mark, and they apply differently to economic and non-economic damages.

At Neumann Law Group, our Michigan personal injury lawyers handle disputes over fault allocation in car accidents, slip and falls, motorcycle crashes, and truck collisions. This page explains how the rules actually work, what changes at 51%, and how PIP benefits sit outside the analysis entirely.

What is comparative fault under Michigan law?

Comparative fault is the rule that lets a jury assign percentages of blame to everyone involved in an accident, including the injured person. Michigan’s version is set out in MCL 600.2959 — what lawyers call modified comparative fault. The “modified” piece matters: there’s a cutoff built into the statute, and your recovery looks very different on either side of it.

Before 1996, Michigan followed pure comparative fault, which let plaintiffs recover even if they were 90% at fault. The legislature changed that. Now there’s a hard line at the halfway point. 50% or less and you can recover the full menu of damages, reduced by your percentage. More than 50% and a substantial portion of your case vanishes.

Under MCL 600.2957, the trier of fact — usually a jury — looks at every person whose conduct contributed to the injury and assigns each one a percentage. Those percentages have to add up to 100. The jury can assign fault to people who aren’t even in the lawsuit, which is why defense attorneys often try to point at absent parties.

How does the 51% rule actually work?

The split between economic and non-economic damages is where most clients get tripped up. Under MCL 600.2959, if your fault is greater than the combined fault of everyone else, two different rules kick in.

Your economic damages — medical bills, lost wages, future treatment costs, property damage — are reduced by your percentage of fault, but you can still recover them. Your non-economic damages — pain and suffering, emotional distress, scarring, loss of enjoyment of life, loss of consortium — are barred entirely. Not reduced. Gone.

Here’s a concrete example. Say a jury values your case at $200,000: $80,000 in economic damages, $120,000 in non-economic damages. The jury finds you 60% at fault. The $80,000 in economic damages is reduced by 60%, leaving $32,000. The $120,000 in non-economic damages is wiped out completely because you’re past the 51% threshold. Final recovery: $32,000.

Now flip it. Same case, but the jury finds you 40% at fault. Both categories are reduced by 40%. Economic damages drop to $48,000, non-economic damages drop to $72,000. Final recovery: $120,000 — almost four times what the same client gets at 60% fault.

This is why the fight over fault percentage often is the case. A 10-point shift can be worth tens or hundreds of thousands of dollars. Defense attorneys spend much of trial trying to push your number above 50%, because everything north of that line costs them only the reduced economic damages.

How does comparative fault interact with Michigan no-fault PIP benefits?

A frequent source of confusion: people assume that if they were at fault for the crash, they can’t get any insurance money. That’s wrong.

Michigan no-fault PIP benefits — covering medical expenses, wage loss, and replacement services — are paid regardless of who caused the collision. MCL 500.3105(2) requires the insurer to pay PIP without regard to fault. If you rear-ended someone because you were looking at your phone, you still get PIP. Your own bad driving doesn’t disqualify you from the no-fault system.

Comparative fault only enters the picture when you step outside no-fault to sue an at-fault driver for non-economic damages. To do that, you have to clear the serious impairment of body function threshold under MCL 500.3135. Once you do, comparative fault applies to whatever the jury awards. The same is true for excess economic damages above your PIP coverage limit — if your medical bills exceed your PIP cap, those excess costs are reduced by your fault percentage. For drivers who chose lower PIP coverage levels under the 2019 no-fault reform, this matters more than ever.

Who decides what percentage of fault you have?

The fault allocation isn’t a number an adjuster picks out of thin air, though that’s often how the negotiation feels. It’s a factual finding the trier of fact makes — judge in a bench trial, jury in a jury trial — after hearing the evidence.

The framework comes from MCL 600.2957 and MCL 600.6304. The fact-finder considers two things: the nature of each person’s conduct, and how directly that conduct caused the harm. Running a stop sign is generally more blameworthy than failing to anticipate someone else’s negligence. Driving impaired is generally more blameworthy than driving distracted. The numbers have to total 100.

Importantly, fault can be assigned to people who aren’t named in the lawsuit. If the evidence shows another driver was also negligent, the jury can put part of the fault on them even though they’re not a defendant. Michigan procedure requires defendants to file notice naming any nonparties they intend to blame, usually within 91 days of filing their answer (MCR 2.112(K)). Most personal injury cases settle before reaching a jury, but settlement value is shaped by what each side thinks a jury would do.

Are there exceptions where my fault percentage doesn’t reduce my recovery?

A few. The biggest involves drunk drivers. Under MCL 600.6312, if a defendant’s harmful act also constitutes certain crimes — including operating while intoxicated under MCL 257.625 — that defendant is jointly and severally liable for the damages they caused.

Here’s why it matters. Michigan generally abolished joint liability under MCL 600.2956 and MCL 600.6304(4). Each defendant is severally liable, paying only their own percentage of fault. If Defendant A is 70% at fault and B is 30% at fault, A pays 70% of the judgment and B pays 30%. If B is uninsured or broke, you bear the loss of B’s share.

The MCL 600.6312 exception flips that for impaired-driving cases. If A was convicted of OWI for the crash, A is jointly and severally liable for the full judgment, even if part of the fault was assigned to B. You can collect 100% from A and let A chase B for contribution. For drunk driving accident victims, this often makes the difference between full and partial recovery. Medical malpractice, wrongful death, and governmental liability cases each follow their own variations on these rules.

What evidence does an attorney use to lower your fault percentage?

Reducing your assigned fault is often the most important work a personal injury lawyer does, and the evidence-gathering happens early — before memories fade and insurance companies build their narrative.

Police reports are the starting point but rarely the ending point. The investigating officer’s opinion isn’t binding on a jury. We’ve handled cases where the report listed our client at primary fault and a jury later assigned them 0%, because the report missed key facts. Independent witness statements, properly preserved, often carry more weight than the police narrative.

Physical evidence — skid marks, vehicle damage patterns, debris fields — can be reconstructed by an expert weeks later, but only if it’s documented quickly. Surveillance footage from nearby businesses, traffic cameras, and dashcams typically gets overwritten on a 30-to-90-day cycle. Cell phone records can establish whether the other driver was texting at impact, but they have to be subpoenaed before the carrier purges them.

For premises liability cases, the open and obvious doctrine often interacts with comparative fault. The defense argues both that the hazard was open and obvious (no duty owed) and that you should have seen it (high comparative fault). Photographs, lighting conditions, store policies, incident logs, and prior similar incidents all factor into the allocation.

Frequently Asked Questions About Comparative Fault in Michigan

Q: Can I still recover damages if I was partially at fault for the accident?

A: Yes. Under MCL 600.2959, you can recover damages as long as you are 50% or less at fault, with your damages reduced by your fault percentage. Even if you’re more than 50% at fault, you can still recover economic damages like medical bills and wage loss — though non-economic damages like pain and suffering are barred at that point.

Q: What’s the difference between comparative fault and contributory negligence?

A: Contributory negligence is an older rule, still followed in a few states, where any fault on the plaintiff’s part bars recovery entirely. Michigan abandoned that doctrine in favor of modified comparative fault under MCL 600.2959, which lets injured plaintiffs recover even when they share some of the blame.

Q: Does comparative fault affect my Michigan no-fault PIP benefits?

A: No. PIP benefits are paid regardless of fault under MCL 500.3105(2). Even if you caused the crash, your own auto insurer must cover medical expenses, wage loss, and replacement services up to your PIP coverage level. Comparative fault only affects damages claims you bring against an at-fault driver.

Q: Who decides what percentage of fault each person has?

A: A judge or jury makes the final determination after considering the evidence — witness testimony, physical evidence, police reports, and expert analysis. The framework is set out in MCL 600.2957 and MCL 600.6304. Insurance adjusters often assign fault percentages during settlement, but those numbers are not binding on a court.

Q: Can fault be assigned to someone who isn’t named in the lawsuit?

A: Yes. Michigan allows juries to assign fault to nonparties — people whose conduct contributed to the injury but who aren’t defendants. Defense attorneys often use this to dilute their client’s share. The defendant has to identify any nonparties they intend to blame within the time limits set by Michigan Court Rule 2.112(K).

Q: Are there situations where a defendant pays more than their fault percentage?

A: Yes, in limited circumstances. Under MCL 600.6312, defendants whose acts also constitute certain crimes — including drunk driving convictions under MCL 257.625 — are jointly and severally liable, meaning the plaintiff can collect the full judgment from them. This is a significant exception to the general several-liability rule.
