What Is Pure Comparative Fault in a Missouri Car Accident?

If you were hurt in a car accident in Kansas City and someone told you that you might be partially at fault, you probably have one big question: can I still get compensated? The short answer is yes. Missouri follows pure comparative fault, which means your recovery is reduced by your share of the blame but never completely eliminated. Even if you were mostly at fault for a crash on I-35 or at a busy Northland intersection, Missouri law still allows you to pursue a claim. Understanding how this system works can make a real difference in the amount you ultimately recover.

At Northland Injury Law, our team has spent over 50 years combined helping Kansas City families navigate exactly these situations. Call us at 816-400-4878 or reach out to our team today for a free consultation. We back every relationship with our 30-Day Satisfaction Guarantee.

How Pure Comparative Fault Works in Missouri Car Accident Law

Missouri uses pure comparative negligence, which allows an injured person to recover damages no matter how much fault is assigned to them. Your compensation is reduced by your percentage of responsibility. If a jury finds your total damages are $100,000 but you were 30% at fault, you would recover $70,000. Even a plaintiff found 99% at fault can still collect the remaining 1%.

This framework is rooted in Missouri statute MO Rev Stat § 537.765, which abolished contributory fault as a complete bar to recovery and established comparative fault. The statute states that any fault chargeable to the plaintiff diminishes compensatory damages proportionately but does not bar recovery entirely. While § 537.765 specifically addresses products liability claims, Missouri courts have broadly applied pure comparative fault principles to negligence actions, including car accidents, since Gustafson v. Benda, 661 S.W.2d 11 (Mo. 1983).

💡 Pro Tip: Document everything after your accident. Photos, witness information, medical records, and your written account all help minimize the percentage of fault assigned to you.

Why Missouri’s System Matters More Than You Might Think

Not every state gives injured people the same opportunity to recover compensation. According to a 50-state survey of negligence laws, over 30 states use modified comparative negligence, which bars recovery if the plaintiff reaches 50% or 51% fault. A handful of states still follow contributory negligence, where being even 1% at fault eliminates your right to damages.

Missouri is one of roughly 12 states that follow pure comparative negligence, alongside New York and California. For Kansas City drivers, this is good news. Insurance companies cannot shut down your claim simply by arguing you share some blame. It’s worth noting that Florida switched from pure to modified comparative negligence in 2023, so the legal landscape can shift.

💡 Pro Tip: Insurance adjusters often inflate your share of fault to reduce payouts. Before giving a recorded statement, talk to a car accident attorney who understands comparative negligence in Missouri.

The Four Elements You Must Prove Before Fault Percentages Matter

Before comparative fault enters the picture, you need to establish that the other driver was negligent. Missouri negligence law requires four elements:

• Duty: The other driver owed you a legal duty of care on the road.

• Breach: They violated that duty through careless behavior like texting, speeding, or running a red light.

• Causation: Their breach directly caused the collision and your injuries.

• Damages: You suffered actual losses like medical bills, lost income, or pain and suffering.

Only after these elements are established does the court examine how fault should be divided. This is where percentages come in, and where strong evidence and experienced legal counsel matter most. Our team at Northland Injury Law has recovered millions in verdicts and settlements, and building a strong foundation on these four elements is where every successful case begins.

💡 Pro Tip: Medical documentation is powerful for proving causation and damages. Follow your treatment plan and keep every receipt. Gaps in treatment give insurers ammunition to minimize your injuries.

How Fault Gets Raised and Divided in a Missouri Car Accident Claim

Comparative fault does not come into play automatically in Missouri. Under MO Rev Stat § 537.765, fault of the plaintiff is an affirmative defense that the defendant must plead and prove. The Missouri Supreme Court reinforced this in Lester v. Sayles, 850 S.W.2d 858 (Mo. banc 1993). If the other driver’s attorney or insurer does not formally assert that you share blame, the court generally will not consider it.

This procedural requirement protects injured people. The burden falls on the defense to prove you did something wrong, not on you to prove you were blameless. A KC auto accident attorney who understands these rules can use them strategically.

What Happens When Multiple Parties Share Fault

Missouri’s joint and several liability rules under RSMo § 537.067 add another layer to how damages are paid. If a defendant bears 51% or more of the fault, that defendant is jointly and severally liable for the full amount of the judgment rendered against the defendants (not limited to economic damages). If a defendant bears less than 51%, they are only responsible for their proportionate share of the judgment. Defendants are only severally liable for punitive damages based on their individual fault percentage.

What the Jury Does Not Know

Missouri law under RSMo § 537.067(3) prohibits any party from telling the jury how the joint and several liability allocation rules will affect the payout. The jury assigns fault percentages without knowing the financial consequences. This is why having a legal team that understands Missouri car accident law deeply can shape your outcome.

💡 Pro Tip: If your crash involved multiple vehicles, comparative fault analysis becomes significantly more complex. Multi-car pileups often require careful reconstruction to assign fault accurately.

How Insurance Companies Use Partial Fault Against You

If you have been in a partial fault car accident in MO, expect the other driver’s insurance company to magnify your role in the crash. Adjusters are trained to find anything they can use to shift blame onto you, from your speed to whether you wore a seatbelt.

We see this regularly with our Kansas City clients, and it’s one of the biggest reasons people leave money on the table. An insurer might offer a quick settlement that already factors in an inflated fault percentage, hoping you will accept before understanding your claim’s true worth. At Northland Injury Law, Voted #1 Accident Lawyer and Best of the Northland, we don’t let that happen. We keep clients informed at every step.

The same comparative fault principles apply whether you were injured in a car, on a bicycle, or as a pedestrian. Our guide on comparative fault in KC bike crash cases walks through the process in detail.

💡 Pro Tip: Never accept the first settlement offer without review. Insurance companies make early offers because most people haven’t calculated the full extent of their medical costs, lost wages, and long-term impact.

Frequently Asked Questions

1. Can I still recover money if I was mostly at fault for my Missouri car accident?

Yes. Under Missouri’s pure comparative fault system, you can recover damages even if you were 99% responsible. Your compensation is reduced by your fault percentage, but you are not barred from recovery entirely.

2. How does the court decide what percentage of fault I share?

The jury (or judge in a bench trial) reviews all evidence and assigns a fault percentage to each party. This includes testimony, police reports, accident reconstruction, and medical records. The defense must raise comparative fault as an affirmative defense for the court to consider it.

3. Does Missouri’s comparative fault rule apply to all car accident cases?

Missouri courts have applied pure comparative fault broadly to negligence cases, including car accidents, since the 1983 Gustafson v. Benda decision. MO Rev Stat § 537.765 codifies pure comparative fault for products liability claims, and the principle extends across personal injury actions through case law.

4. What if the insurance company says I was more at fault than I actually was?

You have every right to challenge the insurer’s fault assessment. This is a common tactic to reduce payouts. A car accident attorney in Kansas City can gather independent evidence to counter inflated fault claims and protect your recovery.

5. Does Missouri’s joint and several liability rule affect my payout?

It can. Under RSMo § 537.067, a defendant found 51% or more at fault may be held jointly and severally liable for economic damages. A defendant under 51% pays only their proportionate share. The jury is not told about these allocation rules when deciding fault percentages.
