Utah's Comparative Fault Rule: How Shared Blame Affects a Claim
Short answer: Utah follows a "modified comparative negligence" rule with a 50% bar: if you're found 49% or less at fault for an accident, you can still recover damages, reduced by your percentage of fault. If you're found 50% or more at fault, you can't recover anything, regardless of how much you were hurt or how much the other party also contributed.
Who this guide is for
Anyone in Utah involved in an accident where fault might be shared between more than one party — most commonly car accidents, but the same rule applies broadly to negligence claims.
How the math actually works
Say a court or insurer determines you were 20% at fault and the other driver was 80% at fault, and your total damages are $10,000. Under Utah's rule, your recovery is reduced by your own percentage of fault — you'd generally be looking at roughly $8,000 (your damages minus your 20% share of fault), not the full $10,000.
The 50% bar — the detail that changes everything
This is the part of Utah's rule with the biggest practical impact: being found 50% or more at fault eliminates your recovery entirely — not reduced, but zero. This means the fault percentage determination isn't just about how much you get; below 50%, it's a math problem, but at or above 50%, it's the difference between recovering something and recovering nothing.
Why the fault percentage determination matters so much
Because the 50% threshold is a cliff, not a gradual slope, how fault gets allocated — and by whom — is a genuinely high-stakes question in any claim where fault is even partially disputed. Insurance adjusters evaluating a claim, and eventually a judge or jury if it goes that far, are the ones making this determination based on the evidence presented.
What the statute also allows: recovering against multiple defendants
Utah's comparative negligence statute also addresses situations with multiple potentially at-fault parties — allowing recovery from any defendant (or group of defendants) whose combined fault exceeds the injured person's own fault percentage, even accounting for parties who are immune from suit or not part of the lawsuit. This can matter in more complex accidents involving more than two parties.
What this site can't tell you
This article explains how the rule works — it can't tell you what percentage of fault applies to your specific accident, or whether a specific fault allocation offered by an insurer is fair. That's a fact-specific determination based on the evidence in your case, and exactly the kind of question worth bringing to an attorney, particularly if you're close to that 50% line or if fault is being disputed at all.
Frequently asked questions
Who decides the fault percentage? In a negotiated insurance settlement, the insurer's evaluation (which you can dispute) generally drives this; if a case goes to trial, a judge or jury makes the determination.
Does this rule apply to all types of accidents, or just car accidents? It applies broadly to negligence-based claims in Utah, not just motor vehicle accidents — though it commonly comes up in that context.
Can I dispute a fault percentage an insurance company assigns to me? Yes — an insurer's fault determination isn't final or binding on its own, and disputing it (with evidence, and often with an attorney's help) is a normal part of the claims process.
