A different kind of stakes, without a cliff edge
Under Missouri's pure comparative fault rule, established in Gustafson v. Benda, there's genuinely no single percentage that eliminates a claimant's recovery entirely — which might suggest fault arguments matter less here than in a state with a hard 50% or 51% cutoff. In practice, the opposite is closer to true: because every single percentage point of assigned fault reduces the recovery directly and proportionally, with no threshold to argue past, insurers have a straightforward, continuous incentive to push that percentage upward at every stage of a claim.
Where this argument actually comes from
The building blocks of a fault argument in Missouri are familiar: the narrative section of the police report, any recorded statement taken from the claimant, witness accounts, photos or video of the scene, and any inconsistencies in how the incident has been described over time.
Why a recorded statement still carries real weight
An early, informal recorded statement is worth genuine caution in Missouri, just as in any state. Without a bar to worry about, the stakes play out differently than in a 50/51-threshold state — there's no single sentence that can wipe out the entire claim — but a phrase that shifts an adjuster's internal fault assessment from 20% to 35% still translates directly into a smaller eventual check, dollar for dollar along the way.
A distinct argument: seat belt non-use
Worth knowing separately: Missouri's seat belt law creates its own damages-mitigation argument, analyzed on its own terms rather than as a straightforward addition to the claimant's comparative fault percentage. Understanding this distinction matters if the subject of seat belt use comes up in negotiations — it isn't simply treated the same way as ordinary comparative fault evidence.
Who ultimately decides
If a case goes to trial, the jury assigns a specific percentage of fault to each party involved, with no cutoff constraining that assignment. In the far more common scenario of a negotiated settlement, the parties effectively work out this same comparison between themselves, each side arguing for the percentage that most favors its position.
