Missouri's Statute of Limitations for Personal Injury
Missouri gives injured plaintiffs five years to file a personal injury lawsuit. The controlling statute is Mo. Rev. Stat. §516.120(4), which covers "any other injury to the person or rights of another, not arising on contract and not otherwise enumerated." Five years is a long runway by national standards — most states impose a two- or three-year deadline. A Missourian injured in a car crash in Kansas City on June 14, 2026 has until June 14, 2031 to file.
That extra time is genuinely useful, but it should not breed complacency. Evidence degrades, witnesses move away, and memories fade. Waiting three or four years to pursue a legitimate claim is a good way to turn a strong case on paper into a weak one in practice. Insurance companies also know the clock is long and may use delay tactics hoping you forget or give up.
When the Clock Starts — and the Discovery Rule
The five-year period ordinarily begins on the date of the injury itself. But Missouri courts recognize a discovery rule for latent injuries: the limitations period can start running from the date you knew, or reasonably should have known, about the injury and its cause. This matters most in toxic exposure cases, occupational diseases, or situations where internal injuries were not immediately apparent. The rule is fact-specific and frequently contested; courts examine what you actually knew and what a reasonable person in your position should have investigated.
Government Claims — Missouri Sovereign Immunity Act
Suing a state agency, city, or county in Missouri involves a completely different procedural framework. Missouri's sovereign immunity generally shields government entities from tort liability, with limited statutory exceptions under the Missouri Tort Claims Act (Mo. Rev. Stat. §537.600 et seq.). The two main categories where immunity is waived are: (1) negligent operation of a motor vehicle by a public employee, and (2) dangerous conditions on public property.
Anyone injured by a government entity must submit written notice of the claim within 90 days of the injury. Miss that 90-day notice window and your claim may be barred entirely — even though the general personal injury limitations period is five years. If your accident involved a city bus in St. Louis, a pothole maintained by the Missouri Department of Transportation, or any other government-owned property or vehicle, the 90-day notice requirement is non-negotiable. Consult a Missouri attorney promptly.
Tolling for Minors
Missouri tolls — pauses — the statute of limitations for minors under Mo. Rev. Stat. §516.170. A child injured before reaching the age of 21 generally has until age 21 to bring a claim, or the five-year period from the date of injury, whichever is longer. This protects children who lack the legal capacity to file suit on their own behalf.
Two deadlines, not one: Missouri's general personal injury statute of limitations is five years under §516.120 — longer than almost any other state. Medical malpractice is a critical exception. Under Mo. Rev. Stat. §516.105, medical malpractice claims must be filed within two years of the date of the alleged negligence (or the date of discovery, whichever applies), subject to a hard ten-year statute of repose. If you were injured by a healthcare provider, the two-year med mal deadline controls — not the five-year general rule.
If your claim involves any healthcare provider — a physician, hospital, nurse, dentist, or pharmacist — treat the filing deadline as two years, not five. Confirm the specifics with a licensed Missouri attorney and review the statute at revisor.mo.gov §516.105.
Pure Comparative Fault — Missouri §537.765
Missouri is a pure comparative fault state. That is the most plaintiff-friendly negligence framework available, and it matters enormously in practice for injured Missourians from Joplin to St. Louis.
Under pure comparative fault, a plaintiff's recovery is reduced by their own percentage of fault — but never eliminated entirely. A plaintiff found 30% responsible for an accident recovers 70% of provable damages. A plaintiff found 70% responsible still recovers 30%. Even a plaintiff who bears 99% of the fault for an accident can technically collect 1% of their damages from a remaining at-fault defendant.
This stands in sharp contrast to modified comparative fault states, where a plaintiff who crosses a threshold — typically 50% or 51% fault — is completely barred from recovery. It is even further from contributory negligence states like Alabama or Virginia, where any fault on the plaintiff's part wipes out the entire claim. Missouri's pure comparative system means that even in cases where both sides share substantial blame, injured parties can still obtain meaningful compensation.
The Statutory Foundation
Mo. Rev. Stat. §537.765 expressly abolishes contributory fault as a complete bar to a plaintiff's recovery and establishes comparative fault in its place. The statute codifies this rule for products liability claims, while the broader pure comparative fault doctrine for general negligence actions traces back to the Missouri Supreme Court's landmark 1983 decision in Gustafson v. Benda. That precedent has governed Missouri tort law ever since.
Practically, when a Kansas City rear-end collision goes to trial and the jury assigns 35% of fault to the injured plaintiff for following too closely, the plaintiff still walks away with 65% of their proven damages. Defense attorneys in Missouri will work to attribute as much fault as possible to the plaintiff — but even aggressive fault-shifting cannot eliminate recovery the way it can in contributory negligence jurisdictions.
Joint and Several Liability — the 51% Rule
Missouri modified its joint and several liability rules under Mo. Rev. Stat. §537.067. When multiple defendants share fault, a defendant found 51% or more at fault may be held jointly and severally liable for the full economic damages awarded — meaning the plaintiff can collect the entire economic judgment from that one defendant, regardless of what the others pay. A defendant assigned less than 51% of fault pays only their proportionate share of economic damages. Punitive damages are always several only: each defendant pays only their own assigned percentage, no matter how high their fault level.
Damage Caps in Missouri — A Complex History
Missouri's damage cap landscape is one of the more legally intricate in the country. The short version: no caps apply to general personal injury cases, but medical malpractice non-economic damages are capped under a statutory framework that has survived multiple constitutional challenges — after an earlier challenge succeeded and the legislature rewrote the law from scratch.
General Personal Injury Cases — No Cap
For personal injury cases not involving healthcare providers — car accidents, slip and falls, dog bites, premises liability, products liability — Missouri does not impose any cap on compensatory damages, including non-economic damages like pain and suffering. Plaintiffs present their full case and juries award what they find appropriate. Punitive damages in non-med-mal cases remain available for egregious, wanton conduct, but are subject to constitutional proportionality review under BMW of North America v. Gore and its progeny.
Medical Malpractice — Watts v. Cox (2012) Strikes Down Original Cap
Missouri's original non-economic damage cap in medical malpractice cases — capping recovery at $350,000 — was struck down by the Missouri Supreme Court on July 31, 2012, in Watts v. Lester E. Cox Medical Centers, 376 S.W.3d 633 (Mo. 2012). The court held, in a 4-3 decision, that the cap violated the Missouri Constitution's right to trial by jury. Because the right to have a jury determine damages was protected at common law when Missouri's constitution was adopted in 1820, the legislature could not override the jury's damages finding by statute.
The 2015 Legislative Response — A Statutory Cause of Action
The Missouri General Assembly responded to Watts with a deliberate structural workaround. Rather than simply re-enacting the same cap — which would have faced the same constitutional problem — the 2015 legislation (SB 239) repealed the common law cause of action for medical malpractice entirely and replaced it with a purely statutory cause of action under a revised Mo. Rev. Stat. §538.210. The legal logic: the constitutional right to jury trial only protects causes of action that existed at common law in 1820. If the legislature abolishes the common law claim and substitutes a statutory one, it can attach whatever damages limitations it chooses to that new statutory right — the common-law jury trial guarantee does not follow.
Current Status — 2015 Caps Upheld as Constitutional
The 2015 re-enacted caps were challenged on constitutional grounds. The Missouri Supreme Court resolved the question in 2021, upholding the post-2015 statutory caps as constitutional. The court confirmed that because the legislature held the authority to abolish the common law cause of action and create a statutory replacement, the Watts decision no longer controlled. The statutory framework survived.
As of 2026, Missouri's non-economic damage cap in medical malpractice cases under §538.210 stands at approximately $481,494 for non-catastrophic injuries and $842,614 for catastrophic injuries. These figures adjust upward by a fixed 1.7% annually from the original statutory amounts of $400,000 and $700,000 established in 2015. "Catastrophic" injuries under the statute include paraplegia, quadriplegia, loss of two or more limbs, significant permanent cognitive impairment, irreversible failure of a major organ, or any other injury a court determines to be catastrophic based on severity and permanence.
Two things are worth emphasizing. First, the caps apply only to non-economic damages — pain and suffering, loss of consortium, emotional distress. Economic damages such as medical bills, lost wages, and future care costs are not capped in any Missouri personal injury case. Second, this area of law has changed multiple times in fifteen years. Anyone facing a medical malpractice claim in Missouri should verify current cap figures and status with a licensed Missouri attorney and consult the official text at revisor.mo.gov §538.210.
Auto Insurance in Missouri — Tort State Rules
Missouri operates under a traditional tort (at-fault) auto insurance system. When an accident happens on I-70 between Kansas City and Columbia, or on I-44 through St. Louis, the driver who caused the crash bears financial responsibility for the injured party's damages. There is no mandatory personal injury protection (PIP) coverage. Injured parties go after the at-fault driver's liability insurance — or their own uninsured/underinsured motorist coverage if that driver lacks adequate insurance.
Minimum Liability Requirements
Missouri requires all drivers to carry liability coverage at minimum limits of 25/50/25:
| Coverage Type | Minimum Required |
|---|---|
| Bodily injury — per person | $25,000 |
| Bodily injury — per accident | $50,000 |
| Property damage — per accident | $25,000 |
These minimums are low relative to the real cost of serious injuries. A single emergency room visit and overnight hospital stay can exhaust a $25,000 per-person limit before a surgical consult even happens. Injured claimants whose damages exceed the at-fault driver's policy limits frequently find themselves turning to their own underinsured motorist (UIM) coverage to bridge the gap.
Mandatory Uninsured Motorist Coverage
Unlike many states, Missouri does not allow drivers to waive uninsured motorist (UM) coverage. Under Mo. Rev. Stat. §379.203, Missouri insurers must provide UM coverage at limits matching the liability minimums. Drivers wanting UM/UIM limits above the 25/50/25 baseline can purchase higher coverage, and doing so is strongly advisable — particularly in high-traffic corridors around Kansas City and St. Louis, where hit-and-run and underinsured driver incidents are a consistent problem.
Practical Notes for Kansas City and St. Louis Claims
Missouri's pure comparative fault system means that insurers operating in Kansas City and St. Louis will routinely argue the injured plaintiff shares fault — because even with no contributory negligence bar, attributing 30% or 40% of fault to the plaintiff reduces the payout by that same percentage. Aggressive fault-shifting is standard practice in high-volume metro accident markets. Document the scene thoroughly, preserve dashcam footage, collect witness names, and avoid giving recorded statements to the at-fault driver's insurer before consulting a Missouri personal injury attorney.
Missouri also has a significant uninsured driver problem. State data has consistently shown that a meaningful percentage of Missouri motorists carry no insurance at all. UM coverage is mandatory under Missouri law, but carrying only the statutory minimum leaves serious gaps when damages are substantial. Personal injury attorneys in St. Louis and Kansas City routinely advise clients to carry stacked UM/UIM coverage well above the floor.
