Missouri Comparative Fault: How Shared Blame Affects Your Injury Claim
Shared Blame Does Not Automatically End a Missouri Injury Claim
If you were injured in a Missouri car crash, truck wreck, slip-and-fall, or other accident, you may worry that your own actions helped cause what happened. Maybe you were glancing at your phone when the other driver ran a red light. Maybe you were not wearing a seat belt. Or maybe an insurance adjuster is already telling you that the accident was partly your fault — and using that to justify a low settlement offer.
Missouri law has a direct answer to that worry: partial fault does not bar you from recovering compensation. Instead, Missouri uses a system called pure comparative fault, under which your recovery is reduced in proportion to your share of the blame — but never eliminated because of it. Understanding this rule is essential before you accept any settlement or agree with an insurer's version of who did what.
What Pure Comparative Fault Means
Under Missouri's pure comparative fault doctrine, adopted by the Supreme Court of Missouri in Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983), a plaintiff's own negligence does not prevent recovery. It only reduces the amount recovered, in proportion to the percentage of fault assigned to the plaintiff. In other words, fault is a sliding scale, not an on-off switch.
This is one of the most injured-person-friendly rules in the country. In some states, being 51% at fault means you recover nothing. In Missouri, you may still recover damages even if you were 99% at fault — your award would simply be reduced by 99%. A person found 25% at fault recovers 75% of the proven damages; a person found 60% at fault still recovers 40%.
How Fault Percentages Are Decided
Fault percentages are decided by a jury — or by a judge in a bench trial — after weighing the evidence. Police reports, witness statements, photos and video, vehicle damage, medical records, and accident reconstruction all feed into that determination. Importantly, comparative fault is an affirmative defense: the defendant must plead it and prove it. You do not start with a presumption of blame on you.
An insurance adjuster's early fault estimate is not binding. It is the opening number in a negotiation, and insurers have a financial incentive to push your percentage as high as possible, because every point of fault assigned to you is a point of money they do not have to pay. Independent evidence — your own photographs, prompt medical treatment, a consistent account of what happened — is how an inflated fault assessment gets challenged.
A Hypothetical Example: How the Math Works
HYPOTHETICAL EXAMPLE FOR ILLUSTRATION ONLY — this is not a real firm case. Suppose a driver runs a stop sign in St. Louis and hits another driver's car. A jury finds the injured driver's total damages are $100,000 and assigns fault: 70% to the driver who ran the stop sign, 30% to the injured driver (for example, for speeding). Under pure comparative fault, the injured driver recovers $70,000 — the full $100,000 reduced by the 30% share of fault.
Now change the numbers: suppose the jury finds the injured driver 80% at fault. She still recovers $20,000. Contrast this with states that bar recovery above 50% fault, where she would recover nothing. That difference is the power of Missouri's pure comparative fault rule.
When More Than One Defendant Is Involved
Accidents often involve multiple responsible parties — two drivers, an employer and a driver, a property owner and a maintenance company. Missouri addresses this in Section 537.067, RSMo, which sets rules for how damages are allocated among defendants.
Under that statute, a defendant found 51% or more at fault may be held jointly and severally liable for the judgment — meaning the plaintiff can collect the recoverable amount from that defendant even if others cannot pay their shares. A defendant found less than 51% at fault is generally responsible only for its own proportionate share. These allocation rules operate behind the scenes; the jury is instructed on fault without being told how the percentages translate into dollars.
Comparative Fault Is the Defendant's Burden to Prove
A point worth emphasizing: in a Missouri personal injury case, the defendant carries the burden of proving your fault. Defense counsel must introduce evidence that your conduct fell below the applicable standard of care and that it contributed to the accident or your injuries. If the defendant cannot prove it, your recovery is not reduced at all.
Common defense arguments include allegations of distracted driving, speeding, failure to wear a seat belt, intoxication, or failure to keep a proper lookout. Each of these must be supported by actual evidence, not speculation. An experienced trial attorney tests those claims — challenging the admissibility of evidence, cross-examining the defense's experts, and making sure the jury hears the full picture of what the defendant did wrong.
Deadlines Matter: Act Before the Clock Runs
Comparative fault battles are won with evidence, and evidence fades. Skid marks wash away, surveillance video is overwritten, witnesses move and forget. That is why early investigation matters even more than early argument.
Missouri also imposes a firm legal deadline. Under Section 516.120, RSMo, most personal injury actions must be filed within five years of the injury. Miss that deadline and the claim is lost regardless of who was at fault. (Shorter deadlines can apply in special situations, such as claims against government entities.) Do not let the statute of limitations quietly erase your rights while you debate fault percentages with an adjuster.
Frequently Asked Questions
Can I still recover compensation if I was mostly at fault for the accident?
Yes. Missouri's pure comparative fault rule means your fault reduces your recovery proportionally rather than barring it. Even if you were found largely responsible, you can still recover the portion of damages attributable to the other party's fault.
What if the insurance company says I was more at fault than I actually was?
You are not bound by the insurer's fault assessment. Fault percentages are ultimately decided by a judge or jury based on evidence, and an inflated assignment can be challenged with independent evidence — witness statements, photographs, police reports, and expert analysis.
Does comparative fault apply to slip-and-fall cases too?
Yes. Missouri's comparative fault doctrine applies broadly across negligence claims, including car accidents, truck wrecks, slip-and-fall and other premises liability cases. A property owner's argument that you were not watching where you were going may reduce your recovery, but it does not eliminate it.
How long do I have to file a personal injury claim in Missouri?
Generally five years from the date of injury, under Section 516.120, RSMo. Certain claims carry shorter deadlines, so do not assume you have the full five years — speak with a lawyer early to protect your rights.
