Missouri follows pure comparative fault, reducing your car accident recovery by your blame percentage without any threshold for denial. The practical effect: a lawyer who can reduce your fault number puts more money in your pocket after fees.
How Pure Comparative Fault Turns Every Percentage Point Into Money
Missouri follows pure comparative fault, which means your recovery shrinks by exactly your assigned fault percentage -- but it never disappears entirely. If you carry 30% fault on a claim, you collect 70% of the total damages. Under a contingency fee, your attorney's cut comes from that reduced amount, so the fault percentage your lawyer negotiates directly controls both your payout and theirs. This creates a concrete financial incentive for aggressive fault negotiation. When evaluating attorneys, ask how they approach the fault-allocation phase of the claim. A lawyer who treats fault percentage as a fixed number set by the police report leaves money on the table. The strongest attorneys challenge fault findings with independent evidence and expert analysis before the demand goes out.
Reducing Your Fault Percentage Through Strategic Evidence and Documentation
Building a low fault percentage in Missouri requires documentation that starts at the crash scene and continues through treatment. Photograph everything before vehicles are moved -- tire marks, debris patterns, traffic signals, and weather conditions. Obtain the names and phone numbers of every witness. Visit a medical provider within 24 hours even if you feel minor soreness, because untreated soft-tissue injuries become the adjuster's favorite tool for questioning causation. Once the evidence package is assembled, your lawyer should present a written counter to the insurer's fault finding supported by physical evidence and independent witness accounts. Do not accept the adjuster's first fault split as settled. In pure comparative states, moving your assessed fault down by even five points increases your net check proportionally, and on a contingency fee that increase benefits both you and your counsel.
A worked example with Missouri’s rule applied
Take a car accident claim with documented losses like these:
| Medical bills | $26,300 |
| Lost wages | $7,800 |
| Other out-of-pocket costs | $1,750 |
| Pain and suffering (3.5× medical) | $92,050 |
| Gross value before fault | $127,900 |
Now apply Missouri’s pure comparative rule. Say the insurer pins 30% of the fault on you: the claim is reduced by $38,370 to $89,530 — 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.
Contingency Fee Math: What You Actually Keep After Legal Costs
Contingency fees typically run 33% before a lawsuit is filed and 40% after filing. On top of the attorney's percentage, case expenses -- filing fees, expert witness charges, medical record retrieval costs -- are deducted from the gross recovery. Your net check is what remains. Understanding this math before you sign the retainer agreement prevents surprises at settlement. Ask each prospective attorney whether expenses come off the top before or after the contingency percentage is calculated, because the order changes your take-home amount. Request a written breakdown showing how a hypothetical recovery would be divided. Attorneys who walk through the numbers openly are signaling confidence in their ability to produce a result worth your share. Those who deflect the question may not be.

Questions
Missouri questions
If I am partly at fault in Missouri, how does that affect my car accident settlement?
Your settlement is reduced by your fault percentage. A claimant found 25% at fault recovers 75% of total damages. Pure comparative fault never bars your claim entirely -- even at 90% fault, you keep 10%. Your attorney's negotiation of the fault percentage directly controls your net recovery and the contingency fee calculation.
Is it worth hiring a lawyer on contingency if I was clearly partly responsible for the crash in Missouri?
Almost always. Even at high fault percentages, pure comparative fault allows partial recovery. A lawyer on contingency only gets paid from what you collect, so the financial risk of hiring one is limited. The more important question is whether the attorney can reduce your fault share -- a five-point reduction on a substantial claim changes your take-home meaningfully.
Can my lawyer negotiate the fault percentage assigned by the insurer in Missouri?
Yes. The insurer's initial fault assessment is a negotiating position, not a legal ruling. Your attorney can challenge it with scene evidence, witness testimony, expert analysis, and vehicle data. In pure comparative states, every percentage point won back adds to your recovery proportionally, making fault negotiation one of the highest-value tasks your lawyer performs.
