Missouri applies pure comparative fault, allowing personal injury recovery regardless of the claimant's share of responsibility. Your award is reduced proportionally — but it is never eliminated.
How Pure Comparative Fault Works in Missouri Personal Injury Cases
Personal injury cases in Missouri are governed by pure comparative fault. This means your compensation is reduced by your percentage of responsibility, but your claim is never eliminated — regardless of how much blame falls on you. If a jury determines you were 30 percent at fault for a car accident, you collect 70 percent of your total damages. If you were 80 percent at fault for a slip and fall, you still collect 20 percent.
The rule applies equally across all personal injury categories: vehicle collisions, premises incidents, animal attacks, and product defects. Insurers in Missouri still benefit from proving your fault because every percentage point lowers their payout. The negotiation focuses on degree rather than on a pass-fail threshold.
Reducing Your Fault Percentage in a Missouri Personal Injury Case
Even though Missouri's pure comparative system allows recovery at any fault level, every percentage point of blame assigned to you reduces your compensation. The strategy is clear: build the strongest possible evidence that the other party caused the incident.
Photograph the scene, secure surveillance footage, and collect witness contact information before leaving. Get medical treatment immediately and describe the mechanism of injury to your physician in precise detail. Follow all treatment recommendations — gaps in compliance are used by adjusters to argue your injuries were less severe than claimed. If a police report or incident report was filed, obtain a copy and review it for accuracy. Challenge any fault characterization that misrepresents your actions. Each documented detail that shifts blame away from you increases your recovery in Missouri.
A worked example with Missouri’s rule applied
Take a personal injury claim with documented losses like these:
| Medical bills | $8,400 |
| Lost wages | $1,900 |
| Other out-of-pocket costs | $2,400 |
| Pain and suffering (3.5× medical) | $29,400 |
| Gross value before fault | $42,100 |
Now apply Missouri’s pure comparative rule. Say the insurer pins 30% of the fault on you: the claim is reduced by $12,630 to $29,470 — but it survives. Even a driver found 30% at fault still recovers the remaining share here, which is exactly why adjusters in pure-comparative states argue percentages rather than trying to kill the claim outright.
Injury Severity and Claim Value in Personal Injury Cases
Personal injury law in Missouri applies the same valuation framework regardless of whether the incident involved a vehicle, a property hazard, an animal, or a defective product. The central variable is injury severity. Soft-tissue injuries with full recovery tend to produce lower settlements because the multiplier applied to economic damages — medical bills and lost income — stays at the lower end of the 1.5 to 5 range.
Fractures requiring surgery, nerve damage, and injuries with lasting functional impact push the multiplier higher. Catastrophic injuries — spinal cord damage, traumatic brain injury, amputations — sit at the top. Your medical records are the primary evidence that establishes your tier. Consistent treatment, detailed physician notes, and diagnostic imaging together build the foundation that determines how an insurer or jury values the claim.

Questions
Missouri questions
Does my fault percentage eliminate my personal injury claim in Missouri?
No. Missouri uses pure comparative fault, which reduces your recovery by your fault percentage but never eliminates it. A claimant found 70 percent at fault still recovers 30 percent of total damages. No threshold bars the claim — only the dollar amount changes based on the fault split.
How is fault percentage determined in a Missouri personal injury case?
Fault is assigned by a jury or through negotiation based on available evidence: police reports, witness testimony, medical records, scene photographs, and surveillance footage. Each party presents their version of the incident, and the factfinder divides responsibility as a percentage. That percentage directly reduces or preserves your recovery.
Is it still worth hiring a lawyer if I was mostly at fault in Missouri?
It can be. Under Missouri's pure comparative system, even a claimant with majority fault retains a proportional right to damages. An experienced attorney may be able to reduce your assigned fault percentage through evidence and negotiation, which directly increases the amount you recover.
