What Is Comparative Fault in Missouri?

Comparative fault—also called comparative negligence—is a legal doctrine that determines how much compensation an injured person can recover when multiple parties share responsibility for an accident. Missouri Revised Statutes § 537.765 establishes Missouri’s comparative fault system.

Under this law, the court assigns each party involved in an accident a percentage of fault based on their contribution to causing the incident. Your compensation is then reduced by your percentage of fault. This applies to all personal injury claims in Missouri, including car accidents, slip and fall cases, motorcycle crashes, pedestrian accidents, and more.

The key difference between Missouri’s system and other states’ systems is that Missouri uses pure comparative fault. This means you can recover damages even if you were 99% at fault for the accident. Your recovery is simply reduced by your percentage of responsibility.

How Missouri’s Pure Comparative Fault System Works

Missouri’s pure comparative fault system is more favorable to injury victims than the modified comparative fault systems used in many other states. Here’s how it works in practice.

You Can Recover Even If You’re Mostly at Fault

Unlike states with modified comparative fault laws—which bar recovery if you’re 50% or 51% or more at fault—Missouri allows recovery regardless of your fault percentage. If you’re 80% at fault, you can still recover 20% of your damages. If you’re 10% at fault, you recover 90% of your damages.

This is why you should never assume you don’t have a case just because you contributed to the accident. The insurance company may tell you that you can’t recover anything because you share fault. That’s often a tactic to get you to abandon your claim.

Calculating Your Recovery Under Comparative Fault

The calculation is straightforward: Your total damages are reduced by your percentage of fault.

Example 1: You’re injured in a car accident and your total damages are $100,000. You’re found to be 25% at fault for the accident because you were traveling slightly over the speed limit. Your recovery would be $75,000 ($100,000 minus 25%).

Example 2: You slip and fall in a store and suffer $50,000 in damages. The jury determines you were 60% at fault for looking at your phone while walking, but the store was 40% at fault for failing to clean up a spill or post warning signs. You would recover $20,000 (40% of $50,000).

Example 3: You’re hit by a car while crossing the street as a pedestrian. Your damages total $200,000. You’re found 10% at fault for crossing mid-block rather than at a crosswalk, while the driver was 90% at fault for texting while driving. You would recover $180,000 (90% of $200,000).

The Dixon Injury Firm has successfully handled numerous cases involving shared fault. Our experience includes negotiating with insurance companies that try to inflate your fault percentage to reduce their payout. With 25+ years of combined legal experience, we know how to counter these tactics and protect your recovery.

Missouri Law vs. Other States’ Comparative Fault Systems

Understanding Missouri’s system helps you appreciate how favorable it is compared to other states:

Pure Comparative Fault (Missouri and 12 other states): You can recover damages no matter your fault percentage, reduced proportionally.

Modified Comparative Fault (51% bar): Some states bar recovery if you’re 51% or more at fault. If you’re 50% at fault, you can recover 50% of damages. If you’re 51% at fault, you recover nothing.

Modified Comparative Fault (50% bar): Other states bar recovery if you’re 50% or more at fault. If you’re 49% at fault, you recover 51% of damages. If you’re 50% or more at fault, you recover nothing.

Contributory Negligence (4 states and DC): In these jurisdictions, if you’re even 1% at fault, you recover nothing.

Missouri’s pure comparative fault system gives injury victims the best chance to recover compensation even when they share some responsibility for an accident.

Common Scenarios Involving Shared Fault in St. Louis Accidents

Snapshot of a person on the phone with an insurance representative, highlighting common situations where shared fault is disputed in St. Louis accident claims.Comparative fault issues arise in many types of accidents. Here are situations where fault is commonly disputed in St. Louis injury cases.

Car Accidents with Shared Fault

Many car accidents involve questions of shared fault. Common scenarios include:

Rear-end collisions: The driver who hits from behind is usually at fault, but if the front driver suddenly reversed or had broken brake lights, they might share fault.

Intersection accidents: When two drivers enter an intersection and collide, determining who had the right-of-way and who failed to yield can result in shared fault findings.

Lane change accidents: If one driver changes lanes without signaling and another driver was speeding, both may share fault for a resulting collision.

Left-turn accidents: A driver turning left across traffic is typically at fault, but if the oncoming driver was speeding excessively or ran a red light, fault may be shared.

Insurance companies frequently try to shift fault onto injury victims in car accident cases. They’ll claim you were distracted, speeding, or failed to take evasive action. Having an experienced attorney who knows how to investigate the accident and gather evidence is critical to establishing accurate fault percentages.

Motorcycle Accidents and Fault Disputes

Motorcycle accidents often involve bias against riders. Insurance adjusters and even juries sometimes assume motorcyclists were speeding or driving recklessly, even when they weren’t.

In motorcycle crash cases, insurance companies may try to assign fault to the rider for:

  • Lane splitting (which is illegal in Missouri)
  • Alleged speeding
  • Failing to wear proper safety gear (even though this doesn’t cause the accident)
  • Not being “visible enough” to other drivers

These tactics are designed to reduce the insurance company’s payout. An attorney experienced in motorcycle accident cases knows how to counter these biases and prove that the other driver’s negligence—not the motorcyclist’s actions—caused the crash.

Pedestrian Accidents and Comparative Fault

Pedestrian accidents in St. Louis frequently involve comparative fault arguments. Drivers and their insurance companies often claim the pedestrian:

  • Crossed outside of a crosswalk
  • Failed to obey traffic signals
  • Wore dark clothing at night
  • Was distracted by a phone
  • Stepped into traffic suddenly

Even when these factors are present, drivers still have a duty to watch for pedestrians and exercise reasonable care. In most pedestrian accident cases, the driver bears the majority of fault because vehicles are inherently more dangerous and drivers have greater responsibility to avoid collisions.

Our firm has successfully represented pedestrians who were crossing mid-block or at night, proving that the driver’s negligence—excessive speed, distraction, or impairment—was the primary cause of the accident.

Slip and Fall Cases and Comparative Negligence

Property owners and their insurance companies almost always argue comparative fault in slip and fall cases. They claim you:

  • Should have seen the hazard
  • Were wearing inappropriate footwear
  • Were distracted or not watching where you were going
  • Were in an area where you weren’t supposed to be

Missouri law does require that you exercise reasonable care for your own safety. However, property owners have a duty to maintain safe premises and warn of hazards. The question becomes: Was the hazard obvious, or did the property owner’s negligence create a dangerous condition that you couldn’t reasonably have avoided?

Don’t let the insurance company convince you that your slip and fall accident was entirely your fault. These cases require careful investigation of the property owner’s knowledge of the hazard, how long it existed, and whether adequate warnings were provided.

How Fault Percentages Are Determined in Missouri

Determining fault percentages is not a precise science. It involves evaluating evidence, applying Missouri traffic laws and negligence principles, and making judgments about what each party should have done differently.

Evidence That Establishes Fault

Multiple types of evidence help determine who was at fault and to what degree:

Police reports: Officer observations and any citations issued can influence fault determinations, though they’re not conclusive.

Witness statements: Independent witnesses provide valuable third-party perspectives on how the accident happened.

Photos and video: Images from accident scenes, security cameras, dashcams, and traffic cameras can show exactly what happened.

Physical evidence: Vehicle damage, skid marks, debris fields, and property damage all tell a story about the mechanics of the accident.

Expert testimony: Accident reconstructionists, engineers, and other experts can analyze evidence and provide opinions on how the accident occurred and who was at fault.

Traffic laws: Violations of Missouri traffic statutes create presumptions of negligence.

Medical records: Injury patterns can corroborate or contradict accounts of how an accident happened.

The Dixon Injury Firm invests in thorough accident investigations. We’ve worked with leading accident reconstruction experts and medical professionals to build strong cases that accurately establish fault. Our team knows what evidence to look for and how to use it effectively in negotiations or at trial.

Who Decides Your Fault Percentage?

The determination of fault percentages happens at different stages depending on how your case proceeds:

Insurance adjuster evaluation: Initially, insurance adjusters for both sides will evaluate the evidence and assign fault percentages. These are often biased in favor of their own insured.

Settlement negotiations: During negotiations, your attorney and the insurance company will dispute fault percentages. Your attorney’s job is to minimize your assigned fault and maximize the other party’s responsibility.

Jury determination: If your case goes to trial, the jury will hear all the evidence and determine each party’s percentage of fault. The judge will instruct the jury on Missouri’s comparative fault law and how to apply it.

Comparative fault instructions: In a trial, the jury receives special verdict forms asking them to determine the total damages and each party’s percentage of fault. The court then calculates your recovery by reducing your damages by your fault percentage.

Most personal injury cases settle before trial, which means fault percentages are usually determined through negotiation between your attorney and the insurance company. Having a lawyer who understands how to prove fault and counter the insurance company’s arguments is critical to maximizing your settlement.

How Insurance Companies Use Comparative Fault Against You

Insurance companies love Missouri’s comparative fault system because it gives them a tool to reduce payouts. Here are common tactics they use.

Inflating Your Fault Percentage

Insurance adjusters routinely assign injury victims higher fault percentages than the evidence supports. They’ll claim you were 60% at fault when the evidence really shows 20% fault. Many accident victims don’t know how to challenge these assessments and accept reduced settlements.

The adjuster’s initial fault determination is just an opening position in a negotiation. An experienced attorney will present evidence and legal arguments to challenge inflated fault percentages and negotiate a more accurate assessment.

Using Your Statements Against You

Anything you say to an insurance adjuster can be used to establish your fault. They’ll ask seemingly innocent questions designed to get you to admit fault:

  • “How fast were you going?”
  • “Did you see the other car before the collision?”
  • “Were you looking at your phone?”
  • “Were you in a hurry?”

Even truthful answers can be twisted to suggest you were at fault. This is why you should never give a recorded statement to the other driver’s insurance company without consulting an attorney first.

Pointing to Traffic Violations

If you received a traffic citation after the accident, the insurance company will use it as strong evidence of your fault. However, a citation doesn’t automatically determine fault percentages, and sometimes officers issue tickets based on incomplete information.

Your attorney can challenge the citation and present evidence showing that even if you violated a traffic law, the other party’s negligence was the primary cause of the accident.

Claiming You Failed to Mitigate Damages

Insurance companies sometimes argue that even if they’re mostly at fault for the accident, you’re partially at fault for your injuries because you:

  • Delayed seeking medical treatment
  • Didn’t follow your doctor’s treatment recommendations
  • Didn’t wear a seatbelt (in car accidents)
  • Didn’t wear a helmet (in motorcycle or bicycle accidents)

Missouri courts have held that failure to wear a seatbelt generally can’t be used to reduce your recovery for injuries, though it can be relevant in wrongful death cases. Helmet laws and other safety equipment issues are more complex and depend on the specific circumstances.

Don’t let insurance adjusters intimidate you with these arguments. Contact The Dixon Injury Firm at (314) 208-288 for a free case evaluation. We’ll review the facts of your case and explain how Missouri’s comparative fault law applies to your specific situation.

How Comparative Fault Affects Your Settlement Value

Understanding how fault percentages impact your settlement helps you evaluate offers and make informed decisions about your case.

Calculating Settlement Offers with Comparative Fault

When the insurance company makes a settlement offer, they’ve already factored in their assessment of comparative fault. For example:

If your damages total $100,000 and the insurance company believes you’re 40% at fault, they may offer $60,000 (or less, because they also want to pay less than full value even after the fault reduction).

Your attorney’s job is to challenge both components: the total value of your damages and the fault percentage. Often insurance companies undervalue damages AND overstate your fault percentage to minimize their payout.

The Importance of Accurately Valuing Your Damages First

Before you can understand how comparative fault affects your case, you need to know the full value of your damages. This includes:

Economic damages:

  • Past and future medical expenses
  • Lost wages and loss of earning capacity
  • Property damage
  • Out-of-pocket expenses related to your injury

Non-economic damages:

  • Pain and suffering
  • Emotional distress
  • Loss of enjoyment of life
  • Disfigurement and scarring
  • Loss of consortium (for family members)

Insurance companies often make lowball offers that undervalue both your total damages and your net recovery after comparative fault. An experienced personal injury attorney knows how to properly value your case and won’t let the insurance company shortchange you on either calculation.

Protecting Your Rights When Fault Is Disputed

If the insurance company claims you share fault for your accident, take these steps to protect your legal rights.

Don’t Admit Fault or Apologize at the Accident Scene

Immediately after an accident, your adrenaline is high and you may not fully understand what happened. Don’t apologize or make statements like “I didn’t see you” or “I wasn’t paying attention.” These statements can be used as admissions of fault.

Stick to the facts when speaking with police: what you observed, where you were going, and the sequence of events as you experienced them. Leave fault determinations to the investigation.

Document Everything Thoroughly

The better your documentation, the stronger your case for minimizing your fault percentage:

At the accident scene:

  • Take photos from multiple angles
  • Photograph traffic signs, signals, road conditions, and sight lines
  • Get contact information for witnesses
  • Note weather and lighting conditions

After the accident:

  • Keep a journal of your injuries, pain levels, and how the accident affects your daily life
  • Save all medical records and bills
  • Document lost wages with pay stubs and employer statements
  • Keep receipts for all accident-related expenses

Don’t Give Recorded Statements to Insurance Companies

You’re required to cooperate with your own insurance company under your policy, but you should have an attorney present before giving a recorded statement. You have no obligation to give a statement to the other driver’s insurance company.

Insurance adjusters are trained to ask questions that elicit answers they can use to establish your fault. They’re not on your side, even when they sound sympathetic.

Consult an Attorney Before Accepting Any Settlement

Once you accept a settlement and sign a release, you give up the right to pursue any further compensation—even if you later discover your injuries are more serious than you thought or your fault percentage was inflated.

Before you accept any offer, have an experienced personal injury attorney review it. At The Dixon Injury Firm, we provide free case evaluations. We’ll tell you honestly whether an offer is fair or whether you should negotiate for more.

Frequently Asked Questions About Missouri Comparative Fault Law

What is Missouri’s comparative fault law and how does it affect my injury claim?

Missouri follows pure comparative fault under RSMo § 537.765, which means you can recover damages even if you were partially at fault for an accident. Your compensation is reduced by your percentage of fault, but you can still recover even if you were 99% at fault. For example, if your damages total $100,000 and you’re found 30% at fault, you’ll recover $70,000.

Can I recover compensation if I was mostly at fault for my accident in Missouri?

Yes. Missouri’s pure comparative fault system allows recovery regardless of your fault percentage. Even if you were 80% at fault, you can still recover 20% of your damages. This is different from modified comparative fault states that bar recovery if you’re 50% or 51% or more at fault.

How is fault percentage determined in a Missouri personal injury case?

Fault percentage is determined by evaluating evidence including police reports, witness statements, photos and video, physical evidence, expert testimony, and applicable traffic laws. During settlement negotiations, your attorney and the insurance company will dispute fault percentages. If your case goes to trial, the jury will determine each party’s percentage of fault based on the evidence presented.

Will the insurance company try to blame me for my accident?

Yes. Insurance companies routinely try to inflate your fault percentage to reduce their payout. They’ll use your statements, traffic violations, and any other evidence they can find to shift blame onto you. This is why you should never give a recorded statement to the other driver’s insurance company without consulting an attorney first.

What should I do if the insurance company says I was partially at fault?

Don’t accept their fault assessment without consulting an attorney. Insurance adjusters often assign higher fault percentages than the evidence supports. Contact The Dixon Injury Firm at (314) 208-2808 for a free case evaluation. We’ll investigate your accident, gather evidence, and challenge inflated fault percentages to maximize your recovery.

Does comparative fault apply to all types of personal injury cases in Missouri?

Yes. Missouri’s comparative fault law applies to car accidents, motorcycle crashes, pedestrian accidents, bicycle accidents, slip and fall cases, and all other personal injury claims. Anytime multiple parties may share responsibility for an accident, comparative fault principles determine how damages are allocated.

How long do I have to file a personal injury lawsuit in Missouri?

Missouri’s statute of limitations gives you five years from the date of injury to file a personal injury lawsuit (RSMo § 516.120). However, you should contact an attorney as soon as possible after an accident. Evidence disappears over time, and early investigation produces stronger cases.

Can I still recover damages if I wasn’t wearing a seatbelt in a car accident?

Generally yes. Missouri courts have held that failure to wear a seatbelt typically can’t be used to reduce your recovery for injuries in most cases. However, there are exceptions, and the insurance company will certainly try to use it against you. An experienced attorney can protect your rights and counter these arguments.

What if the other driver’s insurance company offers me a settlement that accounts for shared fault?

Don’t accept any settlement without having an attorney review it first. Insurance companies often undervalue both your total damages and your net recovery after comparative fault. The Dixon Injury Firm provides free case evaluations where we’ll review any settlement offer and tell you honestly whether it’s fair or whether you should negotiate for more.

How much does it cost to hire a St. Louis personal injury lawyer for a comparative fault case?

The Dixon Injury Firm handles all personal injury cases on a contingency fee basis, which means you pay no upfront costs and no attorney fees unless we recover compensation for you. Our fee comes as a percentage of your settlement or verdict, so you risk nothing by hiring us to fight for your rights. Call (314) 208-2808 today for a free consultation.
