Personal Injury Laws in Missouri: Deadlines, Fault Rules & Damages

The direct answer: In Missouri, you generally have five years from the date of injury to file a personal injury lawsuit for ordinary negligence (car crashes, slip-and-falls, dog bites, and similar claims), under Missouri Revised Statutes (RSMo) § 516.120. Two important exceptions run shorter: medical malpractice claims have a two-year deadline under RSMo § 516.105, and wrongful death claims must be filed within three years of the death under RSMo § 537.080. Miss the applicable deadline and, with rare exceptions, a Missouri court will dismiss the case regardless of how strong it is. Because legislatures and courts amend these rules, always confirm the current text of the statute at the Missouri Revisor of Statutes or with a Missouri attorney before relying on any deadline.

Missouri's Personal Injury Statute of Limitations

• General negligence / personal injury (car accidents, falls, most injuries): 5 years — RSMo § 516.120(4).
• Medical malpractice: 2 years from the act of neglect, with a 10-year outer limit in certain discovery situations — RSMo § 516.105.
• Wrongful death: 3 years from the date of death — RSMo § 537.080.
• Claims against government bodies: often much shorter notice windows (see below) even though the ultimate filing deadline may still track the general statute.

These are the categories most consumers ask about, but Missouri law has other, more specific limitations periods for things like product liability or claims against certain professionals. If your situation doesn't fit neatly into "car accident" or "slip and fall," confirm the applicable period with the current statute text or a Missouri lawyer rather than assuming five years applies.

Missouri's Fault Rule: Pure Comparative Fault

Missouri follows pure comparative fault. The Missouri Supreme Court abolished the old all-or-nothing contributory negligence rule in Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983), adopting the pure comparative fault approach of the Uniform Comparative Fault Act for negligence claims. The legislature later codified pure comparative fault specifically for products-liability claims at RSMo § 537.765.

Under pure comparative fault, a jury assigns a percentage of fault to everyone involved, including the injured person. Your compensation is then reduced by your own percentage of fault — but unlike "modified" comparative fault states, there is no cutoff percentage that bars recovery entirely. Even a plaintiff found 90% at fault can still recover the remaining 10% of their damages. This is a meaningfully more forgiving rule than the 50% or 51% bar used in many neighboring states, so do not assume you have no claim just because you were partly responsible for what happened.

Damage Caps in Missouri

Economic damages (medical bills, lost wages, future care costs) are not capped in Missouri, in any type of personal injury case — this matches the pattern in most states.

Non-economic damages (pain and suffering) are capped only in medical malpractice cases, under RSMo § 538.210. The cap is adjusted annually and, as of 2026, is reported in the roughly $480,000–$485,000 range for non-catastrophic injuries and roughly $840,000–$845,000 for "catastrophic" injuries (defined by the statute to include things like paraplegia, loss of two or more limbs, or significant permanent cognitive impairment). Because this figure changes every year and the amount that applies depends on the trial date, not the injury date, confirm the current number at the Missouri Department of Commerce and Insurance or the statute itself before relying on it. Ordinary negligence cases — car crashes, premises liability, dog bites — do not have a non-economic damages cap in Missouri.

Punitive damages are addressed by RSMo § 510.265, which on its face caps punitive awards at the greater of $500,000 or five times the net judgment. However, the Missouri Supreme Court held in Lewellen v. Franklin (2014) that this cap is unconstitutional as applied to common-law claims that existed before Missouri's 1820 constitution — which covers most ordinary personal injury and fraud claims. In practice, this means the statutory punitive cap is largely unenforceable for classic personal injury claims, though it may still apply to certain purely statutory causes of action. This is a genuinely unsettled and case-specific area; do not assume either way without a lawyer's review of your specific claim type.

Missouri's Car Insurance System: At-Fault (Tort) State

Missouri is an at-fault (tort) state, not a no-fault state. There is no mandatory Personal Injury Protection (PIP) coverage requirement. Instead, the driver who caused the crash — and their insurer — is responsible for the other party's damages.

Missouri's minimum required liability coverage is $25,000 per person / $50,000 per accident for bodily injury and $25,000 per accident for property damage, and the state also requires uninsured motorist coverage of $25,000 per person / $50,000 per accident. Because these are only minimums, and serious injuries routinely exceed them, confirm current requirements at the Missouri Department of Revenue before assuming a specific dollar figure.

Missouri's Dog-Bite Rule: Strict Liability

Missouri applies a strict liability dog-bite statute, RSMo § 273.036. If a dog bites a person who is on public property or lawfully on private property (including the owner's own property) without provoking the dog, the owner or possessor is strictly liable for the resulting damages — regardless of whether the dog had ever bitten anyone before or whether the owner knew the dog was dangerous. This is different from "one-bite" states, where a victim must prove the owner knew the dog was dangerous.

Missouri's pure comparative fault rule still applies to dog-bite claims: if the injured person provoked the dog or otherwise contributed to the incident, damages are reduced by that percentage rather than eliminated. Owners can also face a fine of up to $1,000 under the same statute, separate from any civil damages owed.

Claims Against the Government: Shorter Deadlines and Notice Rules

Missouri, like most states, generally shields state and local government bodies from lawsuits under sovereign immunity, with statutory exceptions for things like motor vehicle accidents involving public employees and dangerous conditions of public property (RSMo § 537.600). Where immunity is waived, damages are also capped, with limits set in RSMo § 537.610 that adjust annually — confirm the current-year figures with the Missouri Department of Commerce and Insurance rather than relying on last year's number.

Separately, some Missouri notice requirements are much shorter than the general statute of limitations. For example, RSMo § 82.210 requires anyone injured by a defective street, sidewalk, or thoroughfare in a city of 100,000 or more residents to give the mayor written notice within 90 days of the injury, describing what happened and stating that the person intends to claim damages. Missouri courts enforce this deadline strictly, and missing it can end an otherwise valid claim before it starts. Other cities, counties, school districts, and state agencies may have their own notice statutes or claims procedures. If your injury involves any government property, vehicle, or employee, treat the deadline as urgent — days or weeks, not years — and confirm the specific notice rule that applies to that entity immediately.

Where to File: Missouri State Courts

Personal injury lawsuits in Missouri are filed in the state's trial courts — the Missouri Circuit Courts — in the county where the injury occurred, where the defendant resides or does business, or another county permitted under Missouri's venue rules. Claims against federal government employees or agencies follow a different process under federal law and are not covered here.

What to Do in Missouri

1. Get medical care and document it. Prompt, consistent treatment protects both your health and your claim.
2. Identify who may be responsible — another driver, a property owner, a dog owner, a medical provider, or a government entity — because the deadline and rules differ by defendant type.
3. If a government entity may be involved, act within days, not months. Look up the specific notice statute or contact the city clerk, county clerk, or relevant agency immediately; some notice windows are as short as 90 days.
4. Preserve evidence — photos, witness names, incident reports, insurance information, and any correspondence.
5. Track your own deadline using the category that matches your claim (5 years general negligence, 2 years medical malpractice, 3 years wrongful death) and build in a safety margin — don't wait until the final weeks.
6. Confirm current numbers before relying on them. Damage caps and government liability limits adjust annually; verify the current figures at the Missouri Revisor of Statutes or Missouri Department of Commerce and Insurance, or with a Missouri attorney.
7. File in the correct Missouri Circuit Court for the county where the injury occurred or where the defendant is located.
