Missouri car insurance claim laws run on a fault-based system: the driver who caused the crash pays, you have five years to sue, and your insurer must acknowledge your claim within 10 working days and accept or deny it within 15 after you finish documenting it. Missouri’s pure comparative fault rule means you can still recover even if you were mostly to blame, and drivers who let their coverage lapse give up the right to non-economic damages.
How Long You Have to Sue
You have five years from the date of the accident to file a lawsuit for personal injury or property damage. Section 516.120 sets that deadline for injury and property claims that don’t arise from a contract.1Missouri Revisor of Statutes. Missouri Code 516.120 – What Actions Within Five Years That’s longer than most states allow, but the clock still matters. Witnesses move, memories blur, and physical evidence disappears.
The five-year window is for court, not for the insurance company. Your policy sets its own reporting and claim deadlines, often measured in days. Blow past those and the insurer can deny the claim even though the statute of limitations has years left to run.
Deadlines Your Insurer Has to Meet
Once you notify the company of a claim, it has 10 working days to acknowledge it. Acknowledgment can take the form of a payment, a written confirmation, or an oral one with a note in the file. In that same 10-day window, the insurer must give you any forms and instructions you need to document the loss.2Cornell Law Institute. 20 CSR 100-1.030 – Failure to Acknowledge Pertinent Communication
After you submit everything the insurer asked for, it has 15 working days to accept or deny the claim.3Secretary of State of Missouri. Missouri Code of State Regulations – 20 CSR 100-1 If the investigation is genuinely complex, the company can take longer, but it has to tell you why and keep you posted. Ignoring these deadlines or stalling without explanation is an improper claims practice under § 375.1007.4Missouri Revisor of Statutes. Missouri Code 375.1007 – Improper Claims Practices
Filing the Claim
Get the other driver’s name, contact details, insurance company, and policy number at the scene. Note the police report number if officers responded. Photograph the vehicles, the scene, and any visible injuries before anything moves. Most insurers accept claims through an app, an online portal, or a phone call. If you want a paper trail, certified mail gives you proof of the delivery date.
Expect the insurer to send a proof-of-loss form. It’s a signed statement covering the date, time, place, vehicles, injuries, and damage. Fill it in carefully. Inaccuracies slow processing and can give the company grounds to fight you later. Stick to what you know, and don’t guess at fault or diagnose injuries a doctor hasn’t confirmed.
What Missouri’s Minimum Coverage Actually Covers
Every driver has to carry liability insurance in a 25/50/25 structure: at least $25,000 for one person’s bodily injury, $50,000 total when multiple people are hurt in a single crash, and $25,000 for property damage.5Missouri Revisor of Statutes. Missouri Code 303.190 – Motor Vehicle Liability Policy, Contents Those are minimums. If the crash you cause produces losses above those numbers, the excess comes out of your pocket. From a claim standpoint, the same ceiling caps what the other driver’s liability policy will pay you if that driver bought only the state minimum.
When the Other Driver Has Too Little Insurance
Every Missouri auto liability policy has to include uninsured motorist (UM) coverage for crashes with drivers who carry no insurance. The law also requires underinsured motorist (UIM) coverage for cases where the at-fault driver’s policy isn’t big enough to cover your injuries. Under § 303.195, UM and UIM limits must match the bodily injury limits on your own liability policy.
You can reject UM and UIM coverage above the state minimum in writing, and the rejection binds everyone on the policy. If you don’t reject, your UM and UIM limits automatically track whatever liability limits you bought.
How Fault Affects What You Recover
Missouri uses pure comparative fault. Your recovery is reduced by your share of the blame, but you’re never cut off entirely. If your damages are $100,000 and a jury finds you 30% at fault, you receive $70,000. A driver found 90% at fault can still collect 10% from the other party. Most states cut off recovery at 50% or 51%, so Missouri sits at the claimant-friendly end of the spectrum.6Justia. Gustafson v. Benda
If You Were Driving Uninsured
Missouri penalizes uninsured drivers even when someone else caused the crash. Section 303.390 waives an uninsured motorist’s right to collect non-economic damages, meaning pain, suffering, and emotional distress, from an insured at-fault driver.7Missouri Revisor of Statutes. Missouri Code 303.390 – Uninsured Motorist, Waiver of Ability to Collect Noneconomic Damages You can still recover economic losses like medical bills, lost wages, and property damage.
The waiver doesn’t apply if the at-fault driver was under the influence of drugs or alcohol, was convicted of involuntary manslaughter, or was convicted of second-degree assault. In those situations, an uninsured claimant regains the right to pursue non-economic damages. The jury never hears about the waiver, so the reduction is applied to the verdict after the fact.
Total Loss and Diminished Value
Missouri treats a vehicle as a total loss when repair costs reach 80% of the car’s fair market value before the accident. Past that point, the insurer pays actual cash value instead of covering repairs. Valuation looks at your car’s condition, mileage, and local market prices, not what you still owe on a loan. If the loan balance is higher than the car’s value, gap insurance is what closes the difference.
Even a repairable car can be worth less after a crash because of its damage history. Missouri allows diminished value claims to recover that drop. The calculation compares pre-crash value to post-repair value, supported by dealer quotes, market comparisons, or a professional appraisal. These claims usually go against the at-fault driver’s liability insurer, and insurers rarely offer the money on their own. You have to ask and document.
When Your Insurer Refuses to Pay
If your own insurer refuses to pay a valid claim without a reasonable excuse, § 375.420 lets a court add penalty damages of up to 20% of the first $1,500 of the loss plus 10% of anything above that, along with reasonable attorney fees.8Missouri Revisor of Statutes. Missouri Code 375.420 – Vexatious Refusal to Pay On a large claim, that adds up quickly.
Section 375.420 has a boundary worth knowing. It explicitly excludes automobile liability insurance. It applies when your own insurer denies a first-party claim under your collision, comprehensive, or UM coverage. It does not apply when the at-fault driver’s liability insurer lowballs or denies your third-party claim. For those disputes, your leverage comes from the improper claims practices statute and common-law bad faith principles instead.4Missouri Revisor of Statutes. Missouri Code 375.1007 – Improper Claims Practices
Subrogation and What It Requires From You
If someone else caused your accident, your own insurer may pay your repairs or medical bills first and then chase the at-fault driver’s insurer for reimbursement. That process is subrogation, and most of it happens between the two companies. If it succeeds, you may get your deductible back, because the at-fault party’s insurer is ultimately paying.
Your part is cooperation. Report the accident promptly, and don’t sign a settlement or release with the other driver’s insurer without telling your own company first. Signing away your insurer’s subrogation rights can breach your policy and leave you owing back the money it already paid on your behalf.
