Missouri Wrongful Death Statute of Limitations: The 3-Year Filing Deadline
Missouri gives your family three years from the date of death to file a wrongful death lawsuit under RSMo 537.100. Learn what starts the clock, the one thing that pauses it, the savings clause, and the companion deadlines that can forfeit your claim.
By Joseph Ott
Your family has three years from the date of death to file a wrongful death lawsuit in Missouri. That is the rule in RSMo 537.100, and Missouri courts enforce it without sentiment. File on day 1,095 or earlier, and your claim lives. File on day 1,096, and it dies — no matter how clear the fault or how deep the loss.
Three years sounds generous. It is not. Grief, probate, insurance negotiations, and criminal proceedings eat months without warning, and several companion deadlines can forfeit your claim even while the three-year clock still runs. This guide walks you through every deadline that matters: the main rule, the one pause the statute allows, the savings clause that gives some families a second chance, and the traps that catch families who wait.
Three years from the date of death — and not a day more
Missouri's wrongful death statute sets a hard filing window. Under RSMo 537.100, every action brought under the wrongful death act must be commenced within three years after the cause of action accrues. One lawsuit per defendant, per death — and it must land inside that window.
Two features of this rule surprise families. First, wrongful death is purely a creature of statute. No such claim existed at common law, a point the Missouri Supreme Court made in Kausch v. Bishop, 568 S.W.2d 532 (Mo. banc 1978). Because the legislature created the right, the legislature's three-year limit defines it. Courts strictly construe statutory causes of action, and judges have little room to bend the deadline for sympathetic families.
Second, the window runs from accrual — and accrual means death. The next section explains why that starting point matters more than any other date in your case.
The clock starts at death, not at the mistake
In most injury cases, the limitations period runs from the negligent act or from its discovery. Wrongful death works differently. Missouri courts have long held that a wrongful death claim accrues on the date of the decedent's death. The Missouri Supreme Court stated the rule in Edmonsond v. Lakeside Hospital Ass'n, 562 S.W.2d 361 (Mo. banc 1978): the claim accrued on the date of death.
That rule produces two practical consequences you should understand.
First, the starting date is almost never in dispute. A death certificate fixes it. You will rarely hear an argument about when the family "should have known" someone died — the event announces itself.
Second, the negligence can be years older than the claim. Say a truck crash in 2022 leaves your father with a traumatic brain injury, and he dies from complications in 2025. Your family's three-year window runs from his 2025 death, not from the 2022 crash. A wrongful death claim can be timely even when the underlying car accident happened years earlier. But the reverse is also true: the date of the mistake never extends your window. Death starts the clock, and only death.
Only one thing stops the clock: a defendant who leaves Missouri
Read RSMo 537.100 closely and you will find exactly one tolling provision. If a defendant is absent from Missouri — or leaves after the claim accrues — so that personal service cannot be had on them here, the time of that absence does not count against the three years. When the defendant returns, the clock resumes.
Nothing else pauses the deadline. Not grief. Not probate. Not settlement talks with an insurer. Not a pending criminal case. Not your child's age. The statute lists its exceptions, and courts apply the list as written.
Two cautions about the absence rule. First, it is a factual defense you must prove — out-of-state presence, the dates, and the inability to serve. Second, it protects against defendants you cannot reach, not defendants you simply have not sued. If you know who caused the death and they live in Missouri, the absence rule gives you nothing.
Your child's deadline is not paused — file for them now
Many families believe the law gives a minor child extra time — until age 18 or 21 — to sue for a parent's death. That belief is dangerous, and you should not rely on it.
Missouri's general disability-tolling statute, RSMo 516.170, lets a person who is under 21 or mentally incapacitated when a claim accrues sue within the normal period after the disability lifts. But by its own terms it covers only the actions "specified" in sections 516.100 through 516.370 — the general limitations chapter. Wrongful death does not live there. It lives in chapter 537, with its own limitation statute that contains no minority toll.
For the actions 516.170 does cover, the protection is real. In Crawford v. Fenton, 701 S.W.2d 772 (Mo. App. 1985), the court applied the statute to toll a chapter-516 limitation during the plaintiff's minority. But nothing in the statute extends that protection across chapters to a wrongful death claim, and no family should bet a claim on a court creating one.
The safe practice is simple. If a child is a wrongful death beneficiary, an adult — a surviving parent, guardian, or next friend — should file for the child inside the same three-year window that governs everyone else. Filing early also preserves evidence, finds witnesses while memories are fresh, and protects the child from any dispute over the question. There is no downside to filing early for a minor, and the downside of waiting could be the entire claim.
The discovery rule rarely rescues a late wrongful death claim
The discovery rule delays accrual when an injury is not reasonably knowable. It rarely fits wrongful death, because the accrual event — the death — is known by definition. You cannot fail to discover that a family member died.
One narrow question remains: what happens when the family knows about the death but not about its wrongful cause? A hospital calls a death natural; two years later, records surface suggesting negligence. Missouri courts approach this situation through the law of concealed causes of action, not the general discovery rule, and they ask when a reasonable person in your position had enough information to investigate. If the death certificate said natural causes and nothing pointed to fault, a court may weigh when the causal link became reasonably knowable.
Treat this as the exception it is. It demands proof, it invites a fight, and families lose it more often than they win. The prudent course never changes: investigate early, while the three-year window is comfortably open, and let a St. Louis wrongful death attorney evaluate causation before the deadline becomes an issue at all.
A second chance exists: the one-year savings clause
RSMo 537.100 gives some families a second filing window, and almost nobody knows about it. If you commenced your action within three years and then took or suffered a nonsuit — a dismissal without prejudice — or you won a verdict that was later arrested or a judgment reversed on appeal, you may commence a new action within one year of that event.
The savings clause matters in real cases. A filing error, a defective party, a jurisdictional dismissal — any of these can end a timely lawsuit without touching its merits. The clause lets you start over within one year, even if the original three years has expired.
Two limits apply. The clause rescues only actions that were filed on time the first time; it cannot revive a claim that was already late. And a 2018 amendment added a service requirement: when the limitation period has already run, you must serve the defendant within 180 days of filing the petition. Miss that 180-day window and the court must dismiss — without prejudice the first time, with prejudice if you have already taken a nonsuit. Second chances in Missouri come with their own deadlines.
Two lawsuits, two clocks: the survival action runs on its own deadline
A death caused by negligence usually creates two distinct claims, and each keeps its own time.
The wrongful death claim belongs to the family. It compensates spouses, children, and parents for what they lost — financial support, companionship, guidance, and funeral expenses. Its deadline is the three-year rule of RSMo 537.100.
The survival action belongs to the decedent's estate. Under RSMo 537.020, a personal injury claim does not die with the injured person; it survives to their personal representative. The estate can recover what the decedent could have claimed while alive — conscious pain and suffering between injury and death, medical bills from that interval, and lost wages. Critically, the survival action keeps the underlying tort's deadline, not the wrongful death deadline. For general negligence, that is five years under RSMo 516.120. For medical malpractice, it is just two years from the negligent act under RSMo 516.105.
That mismatch creates real traps. If negligent medical care injured your spouse in 2023 and killed him in 2025, the wrongful death clock runs to 2028 — but the survival action's two-year malpractice clock may have expired in 2025, before he ever passed away. Track both claims from day one, because preserving one does nothing for the other.
Waiting for the criminal case can forfeit the civil one
When a death involves a crime — a drunk driver, a shooting, criminal negligence — families often want to see the criminal case through before acting. That instinct can cost everything. A criminal prosecution does not toll the wrongful death statute of limitations. The three-year clock runs while the investigation stalls, while charges pend, and while the trial drags toward a verdict.
A murder trial that takes four years leaves no wrongful death claim behind it. The families who preserved their claims filed the civil petition during the criminal case and managed the overlap afterward.
Filing does not mean litigating at full speed. Your attorney can seek protective orders, stay discovery, or sequence depositions so the civil case never interferes with the prosecution. The petition preserves the right; the court's scheduling powers protect both proceedings. Wait for a conviction instead, and you may collect nothing at all.
When the person who caused the death has also died
Fatal accidents sometimes kill the person responsible. When the wrongdoer dies, your claim runs against their estate — and probate law adds deadlines that can cut off recovery long before three years pass.
Missouri's nonclaim statute, RSMo 473.360, bars claims against a decedent's estate that are not filed within six months after the first published notice of letters. An unfiled tort claim against a deceased wrongdoer can die in that six-month window even though the three-year wrongful death period has years left.
If your wrongful death action was already pending when the defendant died, RSMo 473.363 treats it as a duly filed claim once the estate's personal representative is substituted into the case and written notice is filed in the probate division. The substitution and notice steps are yours to complete — the court will not do them for you.
The lesson compresses to one sentence: when the defendant is dead, treat six months, not three years, as your working deadline, and get counsel involved immediately.
What to do this week
Deadlines punish hesitation. If your family lost someone to another's negligence in Missouri, take these steps now:
- Write down the date of death. That date controls the three-year window. Count forward three years and treat that as the last possible day — then plan to act far sooner.
- List every potential claim. Wrongful death, survival action, insurance proceeds, and any workers' compensation death benefits each carry separate deadlines.
- Identify who files for minor children. A guardian or next friend should act for any child beneficiary inside the standard three-year window.
- Do not wait on prosecutors, insurers, or probate. None of them stops the civil clock.
- Gather records while they exist. Death certificate, medical records, crash reports, and witness names get harder to obtain every month.
- Talk to a wrongful death attorney promptly. A consultation costs nothing and pins down the exact deadlines for your facts.
Frequently asked questions
What is the statute of limitations for wrongful death in Missouri?
Three years. Under RSMo 537.100, you must commence the action within three years after the claim accrues, and accrual happens on the date of death. A claim filed after the window closes is barred regardless of its merits.
Does the deadline pause for a minor child?
Not under the statute's plain text. Missouri's minority-tolling statute, RSMo 516.170, covers only the actions listed in sections 516.100 through 516.370, and wrongful death sits outside that range. Have a guardian or next friend file for the child within the same three years that govern every other beneficiary.
What if my case was dismissed without prejudice?
Check the savings clause. If you filed within three years and then took or suffered a nonsuit — or a judgment in your favor was arrested or reversed — RSMo 537.100 lets you commence a new action within one year of that event. When the limitation has run, you must also serve the defendant within 180 days of refiling.
Does a pending criminal case delay the civil deadline?
No. Criminal proceedings never toll the wrongful death statute of limitations. File the civil petition within three years, then coordinate discovery with the criminal timeline through protective orders and scheduling orders.
What is the difference between a wrongful death claim and a survival action?
The wrongful death claim compensates the family for their own losses and runs three years from the death. The survival action continues the decedent's own injury claim through the estate under RSMo 537.020 and keeps the underlying tort's deadline — five years for general negligence, two for medical malpractice. Preserve both by evaluating both from the start.
