Statute of Limitations for Personal Injury Cases in Missouri
Most negligence-based personal injury claims filed in Missouri courts fall under § 516.120(4), which generally provides five years to file a lawsuit.
This rule commonly applies to car accidents, slip and falls, dog bites, premises liability claims, and many other injury cases based on another party’s negligence.
Missouri’s civil court system handles these cases as claims for monetary damages, separate from any criminal prosecution that may arise from the same incident.
A criminal case may punish unlawful conduct, but a civil claim is the path for an injured person to seek compensation for medical bills, lost income, pain, and other documented losses.
The five-year filing period is longer than the deadline used in many states, but it is not universal.
Medical malpractice, wrongful death, intentional torts, and claims involving government entities may involve shorter deadlines, separate notice requirements, or different accrual rules.
Applying the wrong deadline can prevent a claim from moving forward, even when the underlying injury and liability evidence are strong.
What Types of Claims Fall Under The Five-Year Statute of Limitation Period
Most negligence-based civil actions for bodily injury in Missouri fall under the five-year statute of limitations in § 516.120(4).
This deadline generally applies when a person is injured because of someone else’s negligence and no more specific statute sets a shorter filing period.
The five-year period commonly applies to:
Workers compensation claims are different.
Missouri workplace injury claims are generally handled through the workers’ compensation system under Chapter 287, not through the ordinary civil lawsuit process against an employer.
Medical malpractice, wrongful death, intentional torts, and claims involving government entities may also follow separate deadlines or procedural rules.
Assault, battery, false imprisonment, malicious prosecution, libel, and slander generally fall under Missouri’s two-year limitations statute rather than the five-year personal injury rule.
When Does the Statute of Limitations Begin?
In many Missouri personal injury cases, the filing period begins when the injury and its cause are reasonably identifiable.
For a crash, fall, dog bite, or other incident with immediate injuries, the deadline usually runs from the date the accident happened.
Missouri law uses a “capable of ascertainment” standard under § 516.100.
This means the clock may start when the injury and its connection to another party’s conduct are reasonably capable of being discovered, not necessarily when the full extent of harm is known.
Delayed symptoms, latent injuries, or injuries with unclear causes may require a closer review of when a reasonable person would have had enough information to investigate a legal claim.
Missouri’s “Capable of Ascertainment” Rule
Missouri does not always start the statute of limitations on the date of the accident or wrongful act.
Under § 516.100, the filing period begins when the injury is “sustained and capable of ascertainment,” meaning the injury and its likely connection to another party’s conduct are reasonably knowable.
This rule can matter when harm is not immediately apparent, such as delayed spinal symptoms after a crash, a medical complication discovered months later, or an illness later connected to toxic exposure.
The test is objective.
It asks when a reasonable person in the same circumstances would have enough information to investigate a possible legal claim.
Missouri courts have explained that the clock does not begin merely because the wrongful act occurred.
The deadline begins when the available facts would place a reasonably prudent person on notice of a potentially actionable injury.
Knowing that an injury exists may not be enough if the connection to another party’s conduct is not yet reasonably apparent.
Missouri Personal Injury Claims With Different Deadlines
Five years is the default, not the universal rule.
Several common categories of injury cases run on shorter clocks under the Missouri statute of limitations framework.
Certain personal injury cases in Missouri may have significantly shorter deadlines than the standard terms.
Following the wrong statute can end a case before it begins.
Medical Malpractice Claims
Medical malpractice claims in Missouri generally must be filed within two years from the date of the alleged negligent act under § 516.105.
Missouri does not apply a broad discovery rule to every medical malpractice case, so the deadline usually does not wait until the patient discovers the injury.
The statute creates limited discovery-based exceptions.
If a foreign object was negligently left in the body, the claim must be filed within two years from when the negligence was discovered or should have been discovered.
A similar discovery-based rule applies when the claim involves a negligent failure to inform the patient of medical test results.
Missouri also imposes a 10-year statute of repose, which can bar a medical malpractice claim even if the injury was discovered later.
Minors have separate rules under § 516.105, and wrongful death claims based on medical malpractice may involve a different deadline.
Because these rules are narrower than the general personal injury statute, medical malpractice deadlines should be reviewed quickly.
Wrongful Death Claims
Missouri wrongful death claims generally must be filed within three years from the date of death under § 537.100.
These claims arise when a person dies because of another person’s negligence, wrongful act, neglect, or default, with the right to sue created by § 537.080.
The three-year filing period begins on the date of death, not necessarily the date of the underlying injury.
For example, if a person survives for several weeks after a crash and later dies from those injuries, the wrongful death deadline typically runs from the date of death.
Missouri law also limits who may bring the claim.
Section 537.080 gives priority first to the surviving spouse, children, grandchildren, or parents of the deceased.
If no Class 1 claimant exists, the right may pass to siblings or their descendants, and if no eligible family member is available, the court may appoint a plaintiff ad litem to pursue the claim.
Wrongful death claims should be filed in the name of a legally authorized claimant under the statute.
Questions involving standing, class priority, or substitution of parties can create procedural disputes that affect whether the case may proceed.
Exceptions That Can Affect the Time Limit for a Personal Injury Claim
Missouri recognizes certain exceptions that can pause or affect the statute of limitations in limited situations.
These rules are narrower than many people expect, and some exceptions that appear broad in the statute are heavily restricted by later court decisions.
Criminal charges arising from the same incident do not pause the civil filing deadline, and ongoing investigations do not extend the time to file a lawsuit.
Tolling rules also do not apply uniformly across all case types, particularly in medical malpractice litigation.
Certain exceptions may include:
- Claims involving minors or mentally incapacitated individuals: Under § 516.170, the statute of limitations may be paused when the injured person is under 21 or mentally incapacitated at the time of the injury. In many negligence cases, the filing period does not begin until the legal disability ends. These tolling rules are more limited in medical malpractice claims because § 516.105 contains its own timing framework and repose periods.
- Claims where the defendant leaves Missouri: Section 516.200 states that time spent outside the state may not count toward the filing period when the defendant leaves Missouri after the injury occurs. Missouri courts have narrowed this rule substantially, especially when long-arm jurisdiction still allows the defendant to be served despite leaving the state.
- Claims involving statutes of repose or outer filing limits: Some claims carry hard cutoff dates that apply even when tolling doctrines would otherwise extend the limitations period. Missouri medical malpractice claims, for example, are subject to a 10-year statute of repose with limited statutory exceptions.
- Claims involving overlapping tolling theories: Missouri courts generally do not allow multiple tolling doctrines to stack together indefinitely. Attempts to extend the filing period through successive disabilities, repeated absences from the state, or overlapping exceptions are often rejected.
What Does Not Extend the Filing Deadline
Several common steps may help document or value a claim, but they do not pause Missouri’s statute of limitations.
The filing deadline applies to the lawsuit filed in court, not the insurance claim, medical treatment timeline, or settlement discussions.
A person can still lose the right to sue even while an adjuster is communicating, treatment is ongoing, or the full medical picture is still developing.
The filing deadline is not extended by:
- Insurance claims or settlement negotiations: Filing a claim with an insurance company does not stop the statute of limitations. A settlement offer made close to the limitations deadline also does not extend the time to file a lawsuit. If negotiations fail and the deadline passes before suit is filed, the claim may be barred.
- Ongoing medical treatment: Continued treatment, physical therapy, surgery, or hospitalization does not pause the filing period. Medical records may help prove damages, but treatment itself does not preserve the right to sue.
- Waiting to understand the full extent of the injury: Missouri’s capable-of-ascertainment rule focuses on when the injury and its likely cause were reasonably knowable, not when the final prognosis became clear. Waiting too long can create causation disputes, especially when unrelated causes may be blamed for later symptoms.
- Informal promises or discussions with the other side: Statements from an adjuster, defendant, or representative generally do not replace a timely court filing. A significant amount of evidence can also disappear during extended informal discussions, including witness memories, video footage, and physical proof.
What Happens If the Deadline Is Missed?
If a lawsuit is not filed before the applicable deadline, the court may dismiss the case before the facts are ever considered.
In many cases, dismissal on statute-of-limitations grounds prevents the injured person from pursuing compensation for those injuries through the civil legal process.
Once the filing period has expired, the insurer usually has little reason to continue settlement discussions because the threat of litigation is gone.
Delay can also weaken the evidence needed to prove the claim.
Physical evidence may be repaired, discarded, or lost, surveillance footage may be overwritten, and accident reports from older incidents can become harder to obtain.
Witness statements are usually stronger when collected close to the event, before memories fade or details become harder to confirm.
Prompt action helps preserve legal rights and gives the case more time for investigation, medical record collection, and liability analysis.
The injuries suffered must still be connected to the incident through documentation, treatment records, and evidence of causation.
A case filed on time is not automatically successful, but a missed deadline can end the claim before liability or damages are reviewed.
