Missouri allows car accident claimants to recover even when they hold the majority of fault. Your claim payout decreases by your assigned percentage, but no threshold eliminates it.
How Pure Comparative Fault Shapes Claim Negotiations
Under pure comparative fault, the adjuster cannot use your partial responsibility to reject your third-party claim outright. Instead, they assign a fault percentage that scales your recovery downward. A claimant found 45 percent at fault loses 45 percent of the claim value. A claimant found 70 percent at fault still collects 30 percent.
The practical effect on the claim process is significant. Because denial based on fault alone is not available, the adjuster focuses on inflating your percentage. Every piece of evidence in the file — police report language, witness accounts, your own statements — becomes a tool for adjusting that number upward. Responding with counter-evidence is how you preserve claim value.
Reducing Your Fault Percentage in the Claim Process
Your recorded statement is the adjuster's primary tool for establishing fault. Phrases like 'I did not see them until the last second' or 'I might have been going a bit fast' are interpreted as admissions. In a pure comparative state, these statements do not kill your claim — but they increase the fault percentage and reduce your recovery.
Control the information flow. Provide written documentation rather than verbal statements when possible. Let your attorney handle direct communication with the adjuster. Supplement the police report with your own photographic evidence and witness contacts gathered at the scene. The less room the adjuster has to interpret facts against you, the lower your assigned fault percentage.
A worked example with Missouri’s rule applied
Take a car accident claim with documented losses like these:
| Medical bills | $8,400 |
| Lost wages | $3,400 |
| Other out-of-pocket costs | $2,400 |
| Pain and suffering (1.5× medical) | $12,600 |
| Gross value before fault | $26,800 |
Now apply Missouri’s pure comparative rule. Say the insurer pins 30% of the fault on you: the claim is reduced by $8,040 to $18,760 — 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.
How Fault Rules Shape the First-Party and Third-Party Claim Process
Deciding whether to file a first-party claim, a third-party claim, or both depends partly on the fault rule in Missouri. When the rule is strict — barring recovery at lower fault thresholds — pursuing your own policy first protects against the risk that the third-party claim fails on fault grounds.
The third-party claim carries the larger recovery potential because liability policies cover the full scope of damages the at-fault driver caused. But that claim is also where the fault rule applies. The adjuster for the other driver's insurer evaluates your fault percentage and uses it to reduce the offer or deny the claim entirely. Your first-party claim operates outside that fault analysis.

Questions
Missouri questions
How does my fault percentage affect my claim payout under pure comparative fault?
Your fault percentage directly reduces your third-party recovery. If the adjuster assigns you 30 percent fault, you recover 70 percent of your total damages. No fault level — even 99 percent — eliminates your right to file and recover on the claim. The negotiation is about the size of the reduction, not whether you can recover.
Can I file a third-party claim if I was more than 50 percent at fault in Missouri?
Yes. Pure comparative fault states allow recovery at any fault level. The adjuster reduces your payout by your fault percentage but cannot deny the claim based on that percentage alone. The negotiation centers on what fault share is assigned, not on whether you meet a threshold.
How does the adjuster decide what percentage of fault to assign?
The adjuster reviews the police report, physical evidence, witness statements, traffic camera footage, and vehicle damage patterns. They may also use your recorded statement. The assigned percentage is an initial position — it is negotiable, and documented evidence supporting the other driver's fault is your primary tool for pushing the number down.
