How long do you have to file a personal injury claim in Missouri?
Missouri’s personal injury statute of limitations generally gives injured people five years to file a lawsuit, but the deadline does not always start on the accident date.
In most cases involving obvious injuries, the clock begins when the injury and damages are sustained and discoverable, often the accident date.
Wrongful death claims generally have a three-year deadline, while medical malpractice claims generally must be filed within two years, with limited exceptions.
Five years sounds like a long time to file a personal injury lawsuit. In practice, the Missouri personal injury statute of limitations creates a much tighter window than most people expect.
Over time, evidence gets lost, witnesses move, and medical records become harder to link to the original accident. In Missouri, some injury claims also have deadlines that are much shorter than five years.
Knowing how long you have to sue after an injury in Missouri is the first step toward protecting a claim. The sections below break down the general rule, the exceptions, and the practical reasons why waiting is risky even when the deadline has not passed.
Key Takeaways About the Missouri Personal Injury Statute of Limitations
- Missouri gives most personal injury victims five years from the date of injury to file a lawsuit under RSMo § 516.120, but wrongful death and medical malpractice claims have shorter deadlines.
- In limited circumstances involving latent injuries or concealed harm, the discovery rule may delay when the filing clock starts, but Missouri courts apply this exception narrowly.
- Missouri law pauses (tolls) the statute of limitations for minors and for people who lack the legal capacity to act on their own behalf.
- Waiting years to file, even within the legal deadline, often weakens a claim because physical evidence, surveillance footage, and witness memories degrade over time.
How Long Do You Have to File a Personal Injury Lawsuit in Missouri?
Missouri gives most people five years to file a personal injury lawsuit. This deadline comes from RSMo § 516.120 and often applies to negligence claims, car crashes, truck crashes, slip-and-fall injuries, and other injury cases.
In most cases, the five-year clock starts when the injury and damage can be discovered. For car crashes, truck crashes, and slip-and-fall cases, this is usually the date of the accident because the injury is often clear right away.
However, the deadline may be different if the injury or its cause could not reasonably be discovered right away. After the deadline passes, the defendant can ask the court to dismiss the case, even if the injury is serious or fault seems clear.
Missouri’s five-year deadline applies to many common personal injury cases in SEMO, including:
- Car, truck, and motorcycle collisions on I-55 and regional highways
- Slip-and-fall accidents on commercial or residential property
- Pedestrian accidents at intersections or in parking lots
- Industrial accidents and chemical exposure at SEMO worksites
- Freight train vs. vehicle collisions at railroad crossings
Missing the filing deadline may eliminate the claim entirely, even if the at-fault party clearly caused the injury and the damages are well documented.
What Types of Injury Claims Have Different Filing Deadlines in Missouri?
Not every personal injury claim in Missouri follows the five-year rule. Several categories of cases carry shorter deadlines, and confusing them with the general rule may cost you the right to file.
The Missouri personal injury lawsuit deadline varies by claim type:
- Wrongful death: three years from the date of death under RSMo § 537.100
- Medical malpractice: two years from the date of the malpractice under RSMo § 516.105, with limited exceptions for foreign objects and unreported test results, and subject to an absolute 10-year statute of repose
- Claims against public entities: special notice and filing rules may apply depending on the government entity and type of claim. Some municipal claims, including certain street or sidewalk defect claims, may require written notice much sooner than the general five-year deadline.
- Intentional torts: two years from the date of the harmful act under RSMo § 516.140
Each of these deadlines runs independently. A single accident may involve claims with different statutes of limitations if multiple parties or legal theories are involved.
When Does Missouri’s “Capable of Ascertainment” Rule Affect the Filing Deadline?
Missouri does not give every injury claimant extra time simply because they later discover that an injury is more serious than they first believed. Instead, Missouri’s general accrual rule asks when the damage was sustained and capable of ascertainment.
For most standard accident claims, including car crashes and slip-and-fall injuries, the harm is usually capable of ascertainment on the date of the accident.
In those cases, waiting to get a diagnosis or later realizing the injury is worse than expected usually does not restart the filing clock.
The analysis may be different in limited cases involving latent harm, concealed injury, or an injury cause that could not reasonably be identified right away.
These situations are fact-specific, and the injured person may have to prove why the claim could not reasonably have been discovered earlier.
Deadline issues may become more complicated in cases involving:
- Medical malpractice involving a foreign object left in the body
- Failure to inform a patient about abnormal test results
- Toxic exposure where symptoms develop gradually
- Product-related injuries where the connection between the product and the harm is not immediately apparent
- Other latent injuries where the damage or cause could not reasonably be identified right away
These cases should be reviewed individually because Missouri law treats different claim types differently, and some claims have shorter statutes of limitations or statutes of repose.
Does the Statute of Limitations Pause for Minors or Incapacitated People?
Yes, Missouri law pauses the statute of limitations for certain people who lack the legal capacity to file a lawsuit on their own. This pause is called tolling.
Under RSMo § 516.170, the filing deadline does not begin to run until the legal disability is removed. Missouri recognizes two primary tolling situations.
Minors
For many Missouri personal injury claims involving minors, the statute of limitations may be tolled until the injured person turns 21. Different rules may apply in certain cases, including medical malpractice claims. Missouri defines minority for statute-of-limitations purposes as under 21, even though the age of majority for most other purposes is 18.
Legal Incapacity
If the injured person lacks the mental capacity to manage their own legal affairs at the time of the injury, the filing deadline is tolled until the incapacity is removed.
Tolling may also apply if the defendant leaves the state of Missouri after the injury occurs, preventing the plaintiff from serving the lawsuit. The time the defendant is absent from Missouri may not count toward the filing deadline.
What Happens If You Miss the Missouri Personal Injury Statute of Limitations?
Missing the statute of limitations for a personal injury claim in Missouri almost always means losing the right to sue.
The court may dismiss the case on a motion from the defendant, and no amount of evidence or injury severity may overcome a missed deadline.
The consequences of missing the deadline extend beyond the courtroom. Once the filing window closes:
- The at-fault party has no legal obligation to pay anything
- The insurance company may deny the claim outright based on the expired deadline
- Settlement leverage disappears because the insurer knows a lawsuit is no longer possible
- Any money spent on medical treatment or lost wages remains unrecoverable through the legal system
A missed deadline does not mean the injury was not real or that the other party was not at fault. It simply means the law no longer allows the claim to proceed.
Why Does the Filing Deadline Matter Even When You Have Five Years?
Five years is the legal maximum, not a recommended timeline. Waiting even two or three years to pursue a personal injury claim in Missouri may weaken the case significantly, even if the deadline has not passed.
Evidence Degrades Over Time
Physical evidence at an accident scene can disappear quickly as conditions change and records are overwritten. Surveillance footage from businesses near a crash site may be erased within 30 to 90 days, while skid marks can fade and roadway conditions may change.
Vehicles involved in the accident may also be repaired, sold, or scrapped before anyone has a chance to inspect them
Witnesses Become Unreliable
Witnesses forget details, move out of the area, or become harder to locate. A witness who saw a truck run a red light on I-55 near Cape Girardeau may remember the event clearly six months later but struggle to recall specifics after three years.
Medical Records Lose Connection
The longer the gap between an accident and a legal claim, the easier it is for an insurer to argue that the injuries came from something other than the accident.
Prompt medical documentation ties the injury to the event. A multi-year gap gives the adjuster room to dispute that link.

FAQs for Missouri Personal Injury Statute of Limitations
How do I find out which statute of limitations applies to my case?
The applicable deadline depends on the type of claim, the identity of the at-fault party, and when the injury was discovered. A car accident claim follows a different timeline than a medical malpractice claim or a claim against a government entity.
An attorney may identify which statute applies after reviewing the basic facts of the accident and injury.
Do I need a lawyer just to check if my deadline has passed?
No, but speaking with a lawyer is the fastest way to get a clear answer. The statute of limitations involves more than just counting years from the accident date.
Exceptions like the discovery rule, tolling for minors, and entity-specific notice requirements for government claims may change the deadline. Most personal injury attorneys offer initial case reviews at no cost.
What if my injury happened at work in Southeast Missouri?
Workplace injury claims in Missouri may involve different legal rules depending on the circumstances. Cook Barkett Ponder & Wolz handles catastrophic construction site accidents but does not handle workers’ compensation claims.
If the injury resulted from a third party’s negligence rather than a standard workplace incident, a personal injury claim may apply alongside or instead of workers’ compensation.
Does the statute of limitations apply if I already filed an insurance claim?
Yes, the statute of limitations runs regardless of whether you filed an insurance claim. Filing with the insurer does not pause or extend the lawsuit deadline.
If settlement talks stall or the insurer denies the claim, you must still file a lawsuit within the applicable time limit to preserve your legal options.
What if I did not realize my injury was serious until months later?
For most obvious accident injuries, the five-year clock usually starts when the injury and resulting damage are sustained and capable of ascertainment, which is often the date of the accident. Missouri courts apply the discovery rule narrowly.
It may delay the start of the deadline only in limited cases involving latent harm, such as undisclosed medical errors or gradual toxic exposure, where the injured person could not have reasonably known about the injury when it occurred.
Does settling with one defendant affect the deadline for suing another?
No, settling with one defendant does not automatically extend or change the filing deadline for claims against other parties. Each defendant’s statute of limitations runs independently based on when the injury occurred.
If an accident involves multiple at-fault parties, the deadlines for each claim must be tracked separately.
What if the person who caused my injury left Missouri?
Missouri law may toll the statute of limitations if the defendant leaves the state and cannot be served with a lawsuit. The time the defendant is absent from Missouri may not count toward the filing deadline.
However, this tolling provision has limits, and an attorney may help determine whether it applies to your situation.
Does the five-year deadline apply to wrongful death claims in Missouri?
No, wrongful death claims in Missouri have a three-year filing deadline from the date of death, not five years. The wrongful death statute of limitations runs separately from any personal injury claim the deceased person may have had.
Missing the three-year deadline may eliminate the family’s ability to recover compensation for the death.
