Who Can File a Wrongful Death Lawsuit in...

Someone you love has died because another person was careless. Now your family faces a question with a hard legal edge: who gets to sue? Missouri does not leave that choice to the family. RSMo 537.080 picks the plaintiff, ranks the candidates, and allows only one lawsuit against each defendant for one death. Choose the wrong plaintiff, or wait too long, and a strong case can end before it starts.

This guide walks through the three classes of people Missouri lets file, the relatives who are shut out no matter how close they were, the three-year deadline, and the court process that divides any recovery. If you are sorting out your family's position after a fatal accident, start with the class table below — then read the deadline section before you do anything else.

Missouri Law Chooses the Plaintiff — and Allows Only One Lawsuit

At common law, a personal injury claim died with the injured person. Missouri's legislature changed that by statute, so a wrongful death claim exists only because the statute says it does. The statute that creates the claim also controls who brings it. That is why standing fights in these cases are unforgiving: the Missouri Supreme Court has treated wrongful death standing as fundamental, not a technicality a court can waive, and a suit filed by the wrong plaintiff can be dismissed outright (Call v. Heard, 925 S.W.2d 840 (Mo. banc 1996)).

Two features of the statute shape everything else. First, only one action may be brought against any one defendant for one death. Your family gets a single swing at each defendant, whoever holds the bat. Second, one eligible family member can file without gathering signatures from everyone else — but a judge must approve any settlement and supervise how the money is divided. Both rules push in the same direction: get the right plaintiff, early, with the whole family accounted for.

The Three Classes: Who Files, and in What Order

RSMo 537.080 sorts everyone who might sue into three ranked classes. A lower class acts only when the class above it is empty:

| Class | Who may file | When they can act | |---|---|---| | One | Spouse, children, lineal descendants of a deceased child, and the father or mother | Whenever any class-one member exists | | Two | Brothers and sisters, or their descendants | Only if no class-one member exists | | Three | A plaintiff ad litem appointed by the court | Only if no class-one or class-two member exists |

Class one: spouses, children, and parents

Read the statute's first class carefully, because it reaches further than most families expect. It covers the surviving spouse. It covers the deceased's children — natural or adopted, and Missouri long ago erased any distinction based on whether the parents were married. If a child of the deceased has also died, that child's own children step into their parent's place. And it covers the deceased's father and mother, natural or adoptive. Parents belong in class one, on the same footing as a spouse, not in some lower tier that must wait its turn.

Any single class-one member may file alone. A surviving spouse does not need the children's consent; an adult child does not need the surviving spouse's permission. When several class-one members exist, the others do not lose their stake — the court-approval process described below protects their shares. And no rule measures the marriage: a spouse of six months holds the same standing as a spouse of thirty years, though the length of the relationship can matter when a jury measures the loss.

Class two: brothers and sisters

Siblings reach the courthouse only when no class-one plaintiff exists — no living spouse, no children or grandchildren, no parent. Even then, a brother or sister must show a genuine loss under the damages statute, RSMo 537.090, to pursue the claim. Sibling-filed cases are uncommon, because most adults leave behind a spouse, a child, or a parent. They surface most often when a young, unmarried adult with no children dies and both parents are gone.

Class three: the plaintiff ad litem

When nobody in the first two classes exists, the claim does not die. Someone entitled to share in the proceeds may ask the court to appoint a plaintiff ad litem — a suitable person who prosecutes the case on behalf of everyone entitled to share. The court may require a bond. When the plaintiff ad litem wins or settles, the money passes under Missouri's descent laws unless that split would be unfair, in which case the court divides it by each person's actual loss. This backstop keeps a careless defendant from escaping responsibility just because the person they killed left no close family.

Who Cannot File — No Matter How Close the Relationship

The statute's list is closed. If you are not on it, grief and dependence do not put you on it:

Unmarried partners. Missouri does not recognize common-law marriage. A partner of twenty years has no standing; a spouse of twenty days does. This is the statute's hardest edge, and it surprises people constantly.
Stepchildren who were never adopted. The statute covers children "natural or adopted." Raising you from infancy does not substitute for an adoption decree.
In-laws. A mother-in-law, son-in-law, or brother-in-law appears nowhere in any class.
Friends, fiances, and caregivers. Emotional closeness creates no statutory right.

Estrangement cuts the other way. A spouse separated for years — but never divorced — remains in class one. So does a parent who had not spoken to the deceased in a decade. The statute asks who you are, not how close you were. If your family's situation straddles these lines, an attorney can test it against the classes before anyone files.

What Your Family Can Recover Under RSMo 537.090

The damages statute lets the jury award what it finds fair and just for the death, across defined categories: the financial support the deceased would have provided, funeral expenses, and the value of the services, consortium, companionship, comfort, instruction, guidance, counsel, training, and support the family has lost. For a deeper look at how juries value these losses, see our guide to wrongful death damages in Missouri.

Two points surprise families. First, grief itself is not compensable: the statute expressly bars damages for grief and bereavement. The law compensates the lost relationship and support, not sorrow. Second, the deceased's own suffering counts. If your loved one survived the injury for hours or weeks before dying, the jury may award what the deceased could have recovered for that interval had death not followed. A companion survival statute, RSMo 537.085, separately preserves claims the deceased held at death for the benefit of the estate, and the two tracks often run in the same case.

The statute also builds in two presumptions worth knowing. If the deceased was not employed full time but provided at least half the care for a child, a disabled person, or a senior, the law presumes that care was worth 110 percent of the state average weekly wage. If the deceased was a minor, the law presumes the family's pecuniary loss tracks the parents' income. Either side can offer evidence to rebut these figures, but they give families a floor instead of a shrug.

A Judge Approves Every Settlement and Divides the Money

A wrongful death settlement is never a private deal between one relative and an insurance company. Under RSMo 537.095, the filing plaintiff must show the court a diligent attempt to notify everyone who holds a statutory claim. A judge then approves the settlement or enters judgment, states the total, and apportions it among the claimants in proportion to the loss each one proved. Shares are not automatically equal: a young child who lost a lifetime of a parent's guidance may receive more than an adult sibling. The Missouri Supreme Court confirmed in Call v. Heard, 925 S.W.2d 840 (Mo. banc 1996), that trial courts hold broad discretion over that division.

Anyone entitled to share may intervene before the court enters judgment or approves a settlement. If you learn that a relative has filed or is settling without you, that intervention right is your seat at the table — use it promptly, because it closes when the court acts. Minor children receive particular protection: courts scrutinize settlements involving a minor's share, and the apportionment process exists in large part to guard family members who cannot speak for themselves.

Three Years — and Almost No Exceptions

RSMo 537.100 gives your family three years from the date of death to file. When death follows the injury by months — a malpractice complication, a crash victim who lingers — the clock starts at the death, not the negligent act.

The statute lists its own exceptions, and they are nearly the only ones. Time while a defendant is absent from Missouri does not count against the three years. If a case filed on time ends in a nonsuit, an arrested judgment, or a reversal on appeal, the plaintiff may refile within one year. A 2018 amendment adds a trap for late filers: after the limitations period has run, you must serve the defendant within 180 days of filing, or the court dismisses the case.

Do not plan around a grace period. Missouri grants no extension because a family was grieving, and the statute contains no general tolling for minor beneficiaries. A child's share of any recovery is protected, but the family's deadline is not extended while a child grows up. Three years sounds generous until you price what a serious wrongful death case requires: records gathered, experts retained, defendants investigated, and a filing built to survive attack. Start early.

If Your Loved One Was Partly at Fault

Fault does not end the claim. Missouri follows pure comparative fault under RSMo 537.765, a system the Missouri Supreme Court adopted in Gustafson v. Benda, 661 S.W.2d 11 (Mo. 1983). The jury assigns the deceased a percentage of fault, and the family's recovery shrinks by that percentage — but never vanishes, whatever the number. If damages total $1,000,000 and the deceased was 30 percent at fault, the family recovers $700,000. In states with modified systems, 51 percent fault bars recovery entirely; Missouri has no such cliff.

Expect the defense to inflate that percentage. Speeding, an unbuckled belt, a missed warning — each becomes an argument that the deceased caused their own death. Every point the jury adds to the deceased's column comes straight out of the family's recovery, which is why early investigation matters as much as the statute itself.

What to Do Before the Deadline Decides for You

Place yourself in the hierarchy. Spouse, child, grandchild, or parent — class one. Sibling — class two, only if class one is empty. Neither — talk to a lawyer about a plaintiff ad litem.
Decide who files, as a family. One plaintiff files for everyone, and there is only one lawsuit. Agree on the plaintiff early and keep every statutory beneficiary informed.
Preserve evidence now. Vehicles get crushed, video gets overwritten, witnesses move. Photographs, records, and physical evidence secured in the first weeks often decide the case years later.
Decline recorded statements. The other side's insurer will call quickly, sounding kind. Their job is to lock your family into statements they can use against you. Speak with counsel first.
Calendar the three-year date from the death. Then ignore it — plan as if the real deadline were the end of year one, because building the case eats time.
Talk to a lawyer who handles Missouri wrongful death cases. The class rules, the one-action limit, the notice duties, and the apportionment hearing punish improvisation.

Frequently Asked Questions

Who can file a wrongful death lawsuit in Missouri?

RSMo 537.080 ranks three classes. Class one covers the surviving spouse, children, lineal descendants of a deceased child, and the father or mother. Class two — brothers, sisters, or their descendants — acts only when class one is empty. If neither class exists, the court may appoint a plaintiff ad litem. One lawsuit per defendant, per death.

Can an unmarried partner file a wrongful death claim in Missouri?

No. Missouri abolished common-law marriage, and the statute's first class includes only a legal spouse, children, grandchildren, and parents. A partner who shared decades, a home, and children with the deceased still has no standing unless a valid marriage existed.

Do parents count as class one under RSMo 537.080?

Yes. The statute places the father or mother of the deceased — natural or adoptive — in the first class, alongside the spouse and children. Parents never wait for a lower class to open, and a parent may file even when the deceased was an adult with a family of their own.

How long do I have to file a wrongful death lawsuit in Missouri?

Three years from the date of death under RSMo 537.100. The statute pauses the clock only while a defendant is absent from Missouri and gives one year to refile after a nonsuit. Missouri provides no general tolling for grief or for a minor beneficiary, so treat the deadline as fixed and act well inside it.

What if my loved one was partly at fault for the accident?

Your family still recovers. Under RSMo 537.765, Missouri reduces the award by the deceased's percentage of fault but never eliminates it. Thirty percent fault on $1,000,000 in damages leaves $700,000. Insurers fight to raise that percentage, so fault becomes one of the central battles in the case.

Who gets the money from a Missouri wrongful death case?

A circuit court decides. Under RSMo 537.095, a judge approves every settlement, confirms that all statutory beneficiaries were notified, and apportions the proceeds in proportion to each person's proven loss. Anyone entitled to share may intervene before the court acts, and a plaintiff ad litem's recovery passes by the descent laws unless that split would be inequitable.
