After the loss of a loved one, families are often left grieving while also facing urgent legal and financial questions. One of the most common—and confusing—questions is: Who is actually allowed to file a wrongful death claim?

Both Missouri and Illinois limit who may bring a wrongful death lawsuit, and those rules can create complications if families are not aware of them early on.

Who Can File in Missouri

Missouri law sets out a priority system, often referred to as “classes” of eligible claimants.

• First class: The deceased person’s spouse, or natural and adopted parents, children, or descendants of deceased children
• Second class: If no spouse, children, or parents exist, the natural or adopted brother or sister of the deceased or their descendants who can establish a claim to damages from the death
• Third class: If no one in the above classes exists, then a court-appointed plaintiff ad litem may file the claim

Only one wrongful death lawsuit may be filed, even if multiple family members are eligible. If more than one person has equal priority, they must generally join together in a single claim.

Who Can File in Illinois

Illinois law is structured differently. In most cases, the wrongful death claim must be filed by the personal representative of the deceased person’s estate. This person may be:

• Named in a will, or
• Appointed by the court if no estate has been opened

While the personal representative files the lawsuit, the compensation is typically distributed to surviving family members—such as a spouse or next of kin—based on their relationship to the deceased and the losses they suffered. Depending on the situation, the personal representative is typically a close family member or spouse of the deceased.

Common Complications Families Encounter

Wrongful death claims often involve more than just identifying the right family member.

Multiple eligible family members:
Disagreements can arise over who should file the claim or how any recovery should be shared.

No estate or delayed probate:
In Illinois, delays in opening an estate can delay or jeopardize a claim if deadlines are missed.

Estranged or blended families:
Prior marriages, stepchildren, or estranged relatives can complicate eligibility and distribution.

Missed deadlines:
Wrongful death claims are subject to strict statutes of limitation. Missing a filing deadline can permanently bar recovery, even when liability is clear.

Out-of-state issues:
If the death occurred in a different state than where the family lives, determining which law applies can be complex.

Wrongful death laws are designed to provide families a path toward accountability and financial stability—but only if the claim is brought by the right person, in the right way, and on time. Understanding who can file is one of the most important early steps after a loss.
