Missouri has pure comparative fault. How does it affect personal injury cases beyond car accidents?

Missouri's pure comparative fault system (RSMo § 537.765) applies to all personal injury cases — not just car accidents. Slip and fall cases, dog bite injuries, premises liability, and products liability claims all use the pure comparative fault apportionment system. In practice: (1) Premises liability (slip and fall in Kansas City or St. Louis): a business visitor who slips on ice in a parking lot and sues the property owner faces a comparative fault defense — the owner may argue the visitor was comparatively at fault for not watching where they were walking, wearing inappropriate footwear, or ignoring visible ice. The jury assigns percentages; even if the visitor is found 60% at fault, they still recover 40% of their damages under Missouri pure comparative fault. This contrasts starkly with Indiana's 51% bar (where the same 60%-at-fault plaintiff would get nothing); (2) Dog bites: Missouri's dog bite law (RSMo § 273.036) imposes strict liability on dog owners for bites — comparative fault of the victim reduces recovery but does not bar it. A child who teased a dog before being bitten may be found comparatively at fault, reducing the owner's liability proportionally; (3) Products liability: pure comparative fault applies in products liability cases. A consumer who misused a product and was 50% responsible for their injury still recovers 50% of their damages from the manufacturer. Missouri courts have applied comparative fault to strict products liability claims; (4) Dram shop cases: Missouri's limited dram shop liability (RSMo § 537.053 — requires actual knowledge of visible intoxication) is further complicated by comparative fault. An injured party who voluntarily rode with an intoxicated driver may have comparative fault assessed against them; (5) Missouri's 'phantom tortfeasor' doctrine: defendants can submit evidence that a non-party third party was at fault, reducing the defendants' proportional share. Defendants frequently name prior medical providers, later-accident defendants, or non-party employers as fault-sharing non-parties.

Missouri wrongful death claims — who can sue and what damages are available?

Missouri's Wrongful Death Act (RSMo § 537.080 et seq.) creates specific rules for who may bring a wrongful death claim and what damages are available: (1) Plaintiffs who may sue: Missouri's wrongful death statute establishes a strict priority order. Class 1: spouse, children (natural and adopted), and 'lineal descendants' of deceased children (grandchildren, if the child is deceased). If there are no Class 1 members, then: Class 2: parents, siblings, and their descendants. If no surviving Class 1 or Class 2 members, the claim can be brought by the estate of the deceased; (2) Joint plaintiffs: all eligible survivors in the same class must join in one action — Missouri does not allow separate claims by multiple family members in different lawsuits for the same death. One unified wrongful death action prevents inconsistent verdicts; (3) Damages: economic damages: the present value of the decedent's future earnings and services; medical expenses for final illness and injury; funeral expenses. Non-economic damages: loss of consortium, companionship, and services to surviving family members. Missouri has NO cap on wrongful death damages for general tort wrongful death — the Missouri Supreme Court's Watts decision (2012) applies: legislative caps on non-economic damages violate the right to jury trial in the Missouri Constitution for common law claims; (4) Statute of limitations: wrongful death claims must be filed within 3 years of the decedent's death (RSMo § 537.100). Note: this is a separate SOL from the general 5-year personal injury SOL; (5) Apportionment among beneficiaries: when multiple family members share a wrongful death recovery, Missouri courts can apportion the award among eligible beneficiaries based on each person's relationship with and loss of the decedent. Disputed apportionment among surviving family members in Missouri wrongful death cases can create additional litigation within the same court action.

Is Missouri a strict liability state for dog bites?

Missouri imposes strict liability on dog owners for bites under RSMo § 273.036. The elements: (1) The plaintiff was bitten by a dog; (2) The bite occurred while the person was on public property or lawfully on private property; (3) The plaintiff did not provoke the dog. Missouri's strict liability means no 'one bite rule' — unlike states where the owner is only liable if they knew the dog had previously bitten someone, Missouri owners are strictly liable on the first bite. Comparative fault applies: if the plaintiff provoked the dog (even unknowingly), Missouri's pure comparative fault system allows the jury to reduce recovery proportionally based on the provocation. Pure provocation can eliminate recovery entirely (e.g., if someone was 100% responsible for inciting the dog). Missouri's statute covers 'bites' specifically — scratch injuries from dogs may not fall under the strict liability statute and may require proving negligence under traditional premises liability theory. Children are the most common victims of dog bites in Missouri. Missouri's large Labrador retriever, German Shepherd, and pit bull-type dog ownership statewide creates recurring bite cases. St. Louis City and St. Louis County, Kansas City and Jackson County all experience significant dog bite litigation. Insurance angle: Missouri homeowners insurance policies typically cover dog bite liability. Umbrella policies provide additional coverage for claims exceeding homeowners limits. Dog bite injury attorneys in Missouri often pursue claims through the dog owner's homeowners insurer rather than directly against the individual owner, as insurance recovery is more reliable than direct judgment collection against individuals.

What is Missouri's 'dram shop' law and can I sue a bar after a drunk driver injured me?

Missouri's Dram Shop Act (RSMo § 537.053) provides a statutory cause of action against alcohol vendors for injuries caused by intoxicated patrons — but with significant limitations that make Missouri dram shop claims harder to prove than in many states: (1) Required elements: (a) The vendor was licensed to sell alcohol in Missouri; (b) The vendor 'knowingly sold' alcohol to a visibly intoxicated person; (c) The intoxicated person's condition proximately caused the plaintiff's injuries; (2) 'Knowingly sold to a visibly intoxicated person': this is the key limiting element. Missouri requires actual knowledge (or conscious disregard of obvious facts) by the seller that the patron was visibly intoxicated at the time of the sale. Mere serving of alcohol is insufficient; the patron must have been visibly intoxicated and the vendor must have known. Surveillance video of the bar's service interactions with the drunk driver patron is critical evidence in dram shop cases; (3) No social host liability: Missouri courts have consistently held that social hosts (private party hosts who serve alcohol to guests who then drive drunk) are NOT liable under RSMo § 537.053. The statute applies only to licensed vendors, not private individuals serving alcohol at home or private events; (4) Comparison to other states: Massachusetts imposes dram shop liability for serving persons 'visibly intoxicated or who appeared to be under 21.' Tennessee's dram shop law requires 'knowing sale to a visibly intoxicated person.' Arizona's dram shop law requires sale to an obviously intoxicated person. Missouri's standard is similar but more restrictive in practice because 'knowingly sold' has been interpreted strictly; (5) Practical significance: most drunk driving accident recoveries in Missouri come from the drunk driver's own insurance and, if available, the plaintiff's UM/UIM coverage — dram shop claims add an additional defendant but require meeting the specific knowledge standard that makes them harder to prove.

Missouri venue rules — does it matter whether I file my lawsuit in St. Louis or Kansas City?

Missouri's venue rules for personal injury cases are governed by RSMo § 508.010 and have been subject to significant tort reform litigation. Previously, Missouri's rules allowed broad venue selection that attracted out-of-state plaintiffs to file in St. Louis City Circuit Court (the 22nd Judicial Circuit), which historically had plaintiff-favorable jury pools and produced large verdicts. Missouri's tort reform legislation in 2020 amended RSMo § 508.010 to limit venue in personal injury cases: (1) Current venue rules: an individual defendant may be sued in the county where the defendant resides when the action is commenced; or in the county where the cause of action accrued (where the accident happened); or in any county where the defendant was served with process. For corporate defendants: the county of the company's registered agent or principal office in Missouri; or the county where the tort (injury) occurred. The 2020 reform eliminated the provision that allowed any county where the defendant conducted business — which was used to bring non-Missouri cases into the St. Louis City circuit; (2) Venue vs. personal jurisdiction: venue rules determine the proper county within Missouri; personal jurisdiction determines whether Missouri courts can hear the case at all. For out-of-state defendants, Missouri's Long Arm Statute (RSMo § 506.500) allows jurisdiction for torts committed in Missouri or with effects in Missouri; (3) Forum shopping significance: Kansas City (Jackson County) and St. Louis City historically had Missouri's largest personal injury verdicts. With 2020 venue reform, plaintiffs suing Missouri corporations must now file in the location of the defendant's registered office or where the injury occurred — reducing the ability to file an accident-outside-Missouri case in a plaintiff-favorable Missouri venue; (4) Transfer of venue: Missouri courts may transfer venue for the convenience of parties under RSMo § 476.410 when the balance of convenience substantially favors transfer.

Missouri's personal injury law sits at the intersection of a deeply traditional tort state and a frontier of plaintiff-favorable procedural rules. Missouri circuit courts are organized into 45 circuits with 115 counties plus the independent City of St. Louis — a jurisdictional anomaly making the City of St. Louis simultaneously a city and a county in terms of court structure, creating strategic forum considerations for personal injury plaintiffs. The 22nd Judicial Circuit in St. Louis City historically produced some of the largest personal injury and products liability verdicts in the United States before a wave of tort reform efforts limited plaintiffs' ability to venue-shop into St. Louis City from outside Missouri.

Missouri's 1987 Products Liability Act (RSMo § 537.760 et seq.) codified a strict liability standard with specific defenses — including the state-of-the-art defense (the manufacturer could not have known of the risk at the time of manufacture based on available scientific knowledge). Missouri's wrongful death statute (RSMo § 537.080) allows recovery for wrongful death by surviving spouse, minor children, parents of a decedent who left no spouse or children, or siblings if no surviving parents — in that priority order. Missouri has NOT enacted a cap on non-economic damages for general personal injury cases (distinct from medical malpractice), and Missouri juries — particularly in the City of St. Louis and Jackson County (Kansas City) — have historically delivered significant verdicts in catastrophic injury cases. The Missouri Supreme Court's 2012 decision in Watts v. Lester E. Cox Medical Centers, 376 S.W.3d 633, struck down the legislative cap on non-economic damages in medical malpractice cases on state constitutional grounds.

Missouri's Dram Shop Liability

Missouri's dram shop law (RSMo § 537.053) limits alcohol vendor liability compared to many states: a licensed alcohol vendor is liable for damages caused by an intoxicated patron only if the vendor knowingly sold alcohol to a visibly intoxicated person. Missouri's standard requires the vendor had actual knowledge that the patron was visibly intoxicated at the time of sale — a higher standard than mere negligence. Missouri does not impose social host liability for alcohol served at private gatherings, unlike some jurisdictions that hold private hosts liable for serving obviously intoxicated guests who then drive and injure someone. This limitation means Missouri plaintiffs in drunk-driving accident cases typically focus their claims on the at-fault driver rather than the bar or restaurant, unlike in states with broader vendor liability.
