If you've been injured in an accident in Missouri — a car crash on I-70, a fall on an icy sidewalk, a dog bite in Boone County — you have time to pursue compensation. But not unlimited time. Missouri law sets a deadline, called the statute of limitations, for filing a personal injury lawsuit. Miss it, and a court will almost certainly dismiss your case, no matter how serious your injuries or how clear-cut the fault.
Here's what you need to know about Missouri's personal injury statute of limitations, including the exceptions, why the clock sometimes starts later than you'd think, and why five years can feel like plenty of time until it isn't.
Key Takeaways
- In Missouri, the general statute of limitations for personal injury claims is five years from the date of injury, as stated in Missouri Revised Statute § 516.120.
- Shorter deadlines apply in specific cases: two years for medical malpractice, three years for wrongful death, and as little as 90 days to file notice for claims involving government entities.
- Missouri courts enforce filing deadlines strictly. Even compelling claims can be permanently barred if filed after the deadline — resulting in a dismissal with prejudice.
- Missouri's discovery rule can delay the start of the limitations period in cases where the injury or its cause isn't immediately apparent.

Understanding Missouri's Statute of Limitations for Personal Injury
A statute of limitations is a legal deadline. It sets the outer boundary for when you can file a personal injury lawsuit in Missouri's civil court system. Miss that window, and you lose your right to seek compensation through the courts — no matter how serious your injuries.
Under Missouri law, specifically Missouri Revised Statute § 516.120, most personal injury cases must be filed within five years. This applies to common negligence-based injury claims like car accidents, slip and fall incidents, dog bites, and premises liability cases.
Here's what trips people up: this deadline is about when you must file suit, not when you report the accident, get medical treatment, or send a demand letter to an insurance company. Those steps don't stop or pause the clock. Only filing a civil lawsuit in the proper court preserves your legal claim.
Not sure how much time you have left?
Different injuries, different accidents, and different defendants all carry different deadlines in Missouri. A quick call with a personal injury attorney is the safest way to know exactly where you stand. Free consultation — no fee unless we win.

Not all Missouri personal injury lawsuits follow the same timeline. The type of claim you have determines which filing deadline applies. Here's how the main categories break down.
For most personal injury claims — rear-end collisions on I-70, ice-related falls at a Columbia grocery store, dog bite injuries in Boone County — you have five years from the accident date to file suit. This period typically runs from the date of the accident or, in some situations, the date the injury becomes "capable of ascertainment" under Missouri's discovery rule.
However, several important exceptions create shorter filing deadlines that override the general rule.
Medical Malpractice Claims (2-Year Deadline)
In Missouri, the statute of limitations for medical malpractice claims is two years from the date of the alleged negligence — significantly shorter than the general five-year limit. This deadline is set by RSMo § 516.105.
Medical malpractice cases include surgical errors, misdiagnosis, medication mistakes, and failure to diagnose conditions like cancer. The two-year period usually starts on the date of the negligent act itself. Limited exceptions apply — for example, if a surgeon leaves a foreign object inside your body, the clock may start when you discover the problem.
Medical malpractice cases also face additional hurdles: affidavit requirements, damage caps, and more. Waiting until late in the two-year window creates serious risk. Consult a qualified attorney early.
Intentional Injury Claims (Often 2 Years)
Some intentional tort claims in Missouri — assault, battery, false imprisonment — carry a two-year statute of limitations under RSMo § 516.140. Think of situations like being punched in a bar fight, intentionally run off the road, or unlawfully restrained. These are separate from any criminal charges; the civil lawsuit has its own deadline.
Don't assume you have five years if the harm was clearly intentional wrongdoing rather than negligence. An experienced personal injury attorney can help determine which limitations period applies to your specific situation.
Wrongful Death Claims (3-Year Deadline)
A wrongful death claim is brought by surviving family members when someone dies because of another party's negligence or intentional act. The statute of limitations for wrongful death in Missouri is three years from the date of death, under Missouri Revised Statute § 537.100.
Here's a critical distinction: if a person suffers injuries in a January 2024 car accident and dies from those injuries in March 2024, the three-year wrongful death period runs from March 2024 — not from the accident date. A personal injury claim and a wrongful death suit are legally separate, each with its own deadline.
Claims Against Government Entities (Very Short Deadlines)
Claims against government entities in Missouri require filing a notice of claim within 90 days of the accident — a much shorter deadline than the general five-year statute. Under Missouri's sovereign immunity framework, some claims are allowed, such as car accidents involving a government employee driving a state vehicle, or dangerous conditions on public property. But strict compliance with notice rules is required.
This notice requirement is separate from, and in addition to, any longer statute of limitations to actually file suit. Failing to send timely notice can bar the claim entirely, even if the general five-year Missouri personal injury deadline hasn't expired.
When Does the Clock Start? Missouri's Discovery Rule
Figuring out exactly when the statute of limitations begins can be complicated, especially when injuries or their causes aren't obvious right away.
Missouri uses a "capable of ascertainment" standard from RSMo § 516.100. This delays the start of the limitations period until the injury and its cause can reasonably be discovered. In most personal injury cases — a car accident with immediate injuries, broken bones from a fall in a Columbia parking lot — the clock starts on the accident date. The injury is obvious, so the law treats it as immediately knowable.
But the discovery rule matters in cases involving slowly developing conditions caused by toxic exposure, or complications from medical treatment that aren't apparent for months or years. Courts ask: could a careful, reasonable person have discovered the injury and its likely cause? If yes, the clock starts then — even if you didn't actually realize it at the time.
How the Discovery Rule Works in Practice
Consider a mid-Missouri patient who has surgery and discovers 18 months later that a surgical sponge was left inside. Under Missouri's discovery rule, the statute of limitations likely begins when the patient discovered — or reasonably should have discovered — the foreign object, not on the surgery date.
In everyday cases like accidents on I-70 near Columbia, Missouri courts treat the injury as immediately knowable. The five-year or other applicable clock starts right away.
Courts look at when medical records, test results, or other facts would have alerted a reasonable person to the injury and its likely cause. Arguing about discovery-rule timing is fact-intensive and often contested by insurance companies and defense lawyers. If there's any doubt about when your time limit began, talk with an attorney promptly.
Exceptions That Can Extend Missouri's Filing Deadline
Missouri law recognizes limited situations where the statute of limitations is "tolled" — paused — to avoid unfair results. These exceptions are narrow, technical, and strictly interpreted by Missouri courts. People should not assume they qualify without legal guidance.
Even if an exception might extend your deadline, waiting still makes it harder to prove your case. Physical evidence disappears, witnesses move, and medical records become harder to connect to the accident.
Minors and People With Legal Disabilities
Under Missouri Revised Statute § 516.170, if the injured person is a minor or mentally incapacitated at the time of the injury, the statute of limitations is paused until they turn 21 (for minors) or are declared competent. So a 16-year-old hurt in a Boone County car accident may have until age 23 to file certain personal injury lawsuits if the five-year clock doesn't start until age 18.
These disability rules don't extend certain medical malpractice deadlines, which have their own framework. Parents or guardians of injured minors in central Missouri should consult an attorney early — evidence collection and witness memories are still time-sensitive, even if the lawsuit deadline is tolled.
When the Defendant Leaves Missouri or Hides
If the defendant responsible for the injury leaves Missouri after the accident, the time they are absent generally does not count toward the limitations period, under RSMo § 516.200. Modern methods of serving defendants across state lines have reduced how often this tolling actually applies in practice, but it can still be relevant when a negligent party leaves the state shortly after the incident.
What Happens If You Miss Missouri's Statute of Limitations?
If you miss the filing deadline for a personal injury lawsuit in Missouri, your claim is legally barred, and the court will dismiss any lawsuit you file as untimely. Even filing one day late gives the defendant grounds to ask for dismissal — and judges typically grant it.
Dismissal based on the statute of limitations is often "with prejudice," meaning you cannot refile the lawsuit or revive the claim later. Once the deadline expires, you also lose your negotiating leverage: the defendant and their insurance company will no longer take your claim seriously without the threat of legal action. Settlement negotiations collapse when insurers know you can't sue.
If your deadline may be close — or you're worried it has already passed — contact a Missouri personal injury lawyer immediately. There may be a tolling argument or exception that still applies.
Why Acting Quickly Matters, Even With a 5-Year Deadline
Five years sounds like plenty of time. In practice, delay seriously weakens even strong personal injury cases.
Critical evidence — skid marks on the road, damaged vehicles, surveillance video from a Columbia business — can be lost or destroyed within days or weeks after an accident. Witnesses move away, memories fade, and bystanders become harder to track down. Medical records and treatment histories are easier to connect to the accident when you seek care promptly.
Serious cases involving multiple defendants, disputed liability, or complex medical histories take months or years to investigate, negotiate, and prepare for trial. Waiting until late in the limitations period compresses everything and creates unnecessary risk.
Practical Steps to Protect Your Claim Early
Get immediate medical treatment after any significant accident. This protects your health and creates a documented connection between the accident and your injuries.
Preserve evidence right away: photos of the scene, vehicle damage, and visible injuries; contact information for witnesses and responding officers; copies of accident reports and police reports.
Keep organized records of your medical bills, lost wages, mileage to treatment, and any communications with insurance adjusters.
Talk with a personal injury attorney before giving recorded statements or signing insurance documents. Early legal counsel allows your attorney to send preservation letters, manage negotiations, and still have time to file suit if the insurance company refuses to pay fair compensation.
