How Long Do Sexual Abuse Survivors Have to File a Lawsuit in Missouri?

It depends on your age then and on whom you sue. A survivor abused as a child can sue the abuser until ten years after turning 21, or three years after discovering the abuse caused the injury, whichever is later (RSMo 537.046). Adults have two years against the attacker (RSMo 516.140) and five against a negligent institution (RSMo 516.120).

A survivor’s case rarely has one deadline. It has one for each defendant and each kind of claim, and the one that matters is whichever runs out first.

01What Is the Deadline for a Survivor Abused as a Child?

Missouri has a statute written for this situation. A claim for injury caused by childhood sexual abuse must be filed within ten years after the survivor turns 21, or within three years after the survivor discovers, or reasonably should have discovered, that the injury was caused by the abuse, whichever comes later (RSMo 537.046.2). For most survivors, the first test means the 31st birthday. The second can run much longer.

The statute defines childhood sexual abuse by reference to the criminal code: an act committed against someone under 18 that would have violated one of the listed Missouri offenses, which include rape, sodomy, child molestation, sexual abuse, incest and sexual trafficking of a child (RSMo 537.046.1). No criminal charge is required. The question is whether the act would have been one of those crimes.

The injury can be psychological alone. The statute says so expressly, and a psychological injury need not come with any physical one. The current version also makes a nondisclosure agreement unenforceable and void in a dispute over childhood sexual abuse claims (RSMo 537.046.4).

The legislature rewrote the section in 2025, effective August 28, 2025. The ten-year and three-year periods did not change. The rewrite brought the list of crimes in line with the current criminal code, added the rule on nondisclosure agreements and removed language from the 2004 version that tried to revive expired claims. Earlier versions listed fewer offenses, so the list that applies can depend on when the abuse happened. The new text says it applies to any action “arising on or after August 28, 2025” (RSMo 537.046.3). No court has yet construed that phrase. Because the 2004 and 2025 versions set the same periods, the deadline is the same whichever version applies: ten years after age 21, or three years after discovery, whichever is later.

Can an old claim be revived?

Not once it has expired under the law in force at the time. The Supreme Court of Missouri held that when a limitation period runs out, the defendant gains a vested right to be free from suit, and the Missouri Constitution’s ban on retrospective laws prevents a later statute from reviving the claim (Doe v. Roman Catholic Diocese of Jefferson City, 862 S.W.2d 338, Mo. banc 1993). That is why the date of the abuse, the survivor’s birthday and the history of the statute all have to be read together.

02Does the Childhood Abuse Statute Reach a School, Church or Youth Organization?

No. The Supreme Court of Missouri held that section 537.046 “creates a cause of action only against the person who allegedly committed the abuse” and gives no claim against non-perpetrators such as a youth organization. It also held that the longer period does not extend the separate battery and negligence claims (State ex rel. Heart of America Council v. McKenzie, 484 S.W.3d 320, Mo. banc 2016).

The court agreed with an earlier federal appeals decision that reached the same result for a school district. That court reasoned that a defendant who did not commit one of the listed acts cannot have caused injury by “childhood sexual abuse” as the statute defines it (Walker v. Barrett, 650 F.3d 1198, 8th Cir. 2011).

So the claim against the institution runs on the ordinary clock. Negligent supervision, negligent hiring or retention, and failure to protect are claims for “injury to the person” with a five-year limit (RSMo 516.120(4)). For a survivor who was under 21 when the claim accrued, Missouri pauses that clock until the 21st birthday (RSMo 516.170). In McKenzie, the court’s own arithmetic followed that rule: the battery claim expired at 23 and the negligence claim at 26.

Missouri’s longest civil deadline for childhood abuse runs against one person, the abuser. The institution that let it happen is usually on a much shorter clock.

03When Does the Clock Start if You Did Not Understand the Harm Until Later?

Missouri’s general rule is that a claim accrues not when the wrong is done, but when the resulting damage “is sustained and is capable of ascertainment” (RSMo 516.100). That rule governs the five-year claim against an institution, and it can move the starting date.

In Powel v. Chaminade College Preparatory, Inc., 197 S.W.3d 576 (Mo. banc 2006), a former student sued his school under the five-year statute, alleging he had repressed his memory of the abuse until adulthood. The Supreme Court of Missouri reversed a ruling that the clock started at the time of the abuse. It held the test is objective: the question is when “a reasonable person would have been put on notice that an injury and substantial damages may have occurred.” If the memory was repressed before that point, the claim does not accrue until the memory returns.

Powel also held that when the evidence about what the survivor knew points in different directions, the timing is a question of fact for the jury. The rule cuts both ways. If a reasonable person would have known of the injury and its cause earlier, the clock started earlier, and McKenzie noted that outside repressed-memory cases the damages are usually ascertainable when the conduct occurs.

A separate statute stops the clock when a defendant, by concealing himself or by any other improper act, prevents a lawsuit from being filed, until that obstacle ends (RSMo 516.280). Whether particular conduct qualifies is fact-specific and often contested.

04What Deadlines Apply to a Survivor Who Was an Adult?

Two years for a claim of assault or battery against the person who did it (RSMo 516.140). Other claims against the attacker, such as intentional infliction of emotional distress, have been held to carry five years (Walker v. Barrett). Five years for a negligence claim against a business, employer, landlord or other institution whose own failures made the assault possible (RSMo 516.120(4)). The general rules on hotels, and why the split matters, are on our hotel sexual assault page at /sexual-assault/hotel-sexual-assault/, and our article at /blog/can-i-sue-a-hotel-for-an-assault-in-missouri/ explains when a hotel is responsible.

One Missouri statute applies at any age. A claim for personal injury caused by sexual contact by a person within the third degree of affinity or consanguinity, meaning a close relative by blood or marriage, has a ten-year limitation (RSMo 516.371).

The pause in RSMo 516.170 is not only for minors. It also applies to a person who was mentally incapacitated when the claim accrued, with the period running after the incapacity ends. Whether a survivor’s condition meets that standard is a medical and legal question, not an assumption.

If the survivor has died

If the abuse or assault caused a death, the family’s wrongful death claim must be filed within three years (RSMo 537.100). If a survivor died of something else, whether their own claim can still be pursued by the estate is a different question with different rules.

05What Changes When the Defendant Is a Public School, University or Police Department?

Almost everything. Missouri keeps sovereign immunity for public entities and waives it for negligence in only two situations: injuries from the operation of motor vehicles by public employees, and injuries caused by a dangerous condition of public property (RSMo 537.600). Neither describes most abuse by a teacher, coach or officer.

Immunity can also be waived to the extent a public entity buys liability insurance, but only up to the policy’s limits and only for the purposes it covers (RSMo 537.610). That makes the policy itself one of the first documents to obtain.

Claims involving a public school or police department are often brought under federal law instead, such as Title IX or the federal civil rights statute, 42 U.S.C. § 1983. Neither has a deadline of its own. Federal courts in Missouri borrow the state’s five-year personal injury limit, RSMo 516.120(4), not the longer childhood abuse statute (Walker v. Barrett, 650 F.3d 1198, 8th Cir. 2011; Sulik v. Taney County, 393 F.3d 765, 8th Cir. 2005). A public defendant does not mean there is no claim. It means the analysis starts from a different place, and the deadline answer may be different too.

06What Federal Deadlines Can Apply?

Two federal statutes give survivors longer windows than Missouri does. A trafficking survivor’s civil claim must be filed within ten years after the claim arose or, if the survivor was a minor, within ten years after turning 18, whichever is later (18 U.S.C. § 1595(c)).

A person who was a victim, while a minor, of certain federal crimes has a civil claim with no time limit at all (18 U.S.C. § 2255(b)). The listed crimes include sex trafficking, federal sexual abuse offenses, producing or distributing images of child sexual abuse, and transporting or enticing a minor across state lines for sexual activity. The injury does not have to have occurred while the person was a minor.

These claims are filed in federal court, here the Eastern District of Missouri. They depend on facts that fit the federal crimes, so not every case qualifies.

07What if the Abuse Happened in Illinois?

Many St. Louis families have ties across the river, and abuse at a camp, school or relative’s home in the Metro East may be governed by Illinois law. Illinois allows a childhood sexual abuse claim to be filed at any time (735 ILCS 5/13-202.2(f)). That rule applies only to claims that had not already expired under an earlier limit when Illinois removed it, so older abuse still requires a date-by-date review.

For adults, the general Illinois limit for personal injury is two years (735 ILCS 5/13-202). It does not run while a survivor of sexual conduct or penetration is subject to threats, intimidation, manipulation or fraud by the perpetrator or someone acting for them (735 ILCS 5/13-202.3). And a claim against a person convicted of first degree murder, a Class X felony or a Class 1 felony based on that conduct may be brought at any time (735 ILCS 5/13-202.1).

An Illinois case usually needs a lawyer licensed in Illinois, and which state’s law applies can itself be disputed.

08Does the Criminal Deadline Change the Civil One?

No. They are separate clocks. In Missouri, a prosecution for rape in the first degree, sodomy in the first degree or any class A felony may be commenced at any time (RSMo 556.036.1). A prosecution for an unlawful sexual offense involving a person 18 or under may also be commenced at any time (RSMo 556.037). Other felonies generally have three years and misdemeanors one (RSMo 556.036.2).

None of those rules extends a civil deadline. A prosecutor can file charges decades later, after every civil claim has expired. The reverse is also true. A case the state never charged, dismissed or lost at trial does not shorten or end the civil claim, which has its own deadline and a lower burden of proof.

Waiting for the criminal case to finish before talking to a civil lawyer is one of the most common ways a civil deadline is missed. The two can proceed at the same time.

09Why Not Wait, Even When the Deadline Is Years Away?

A long legal window does not mean the evidence will last as long. Survivors should take whatever time they need to heal, but the records do not wait.

• Institutions keep records under retention schedules. Personnel files, complaint logs, incident reports and emails about a teacher, coach or employee can be destroyed on a routine cycle unless someone asks that they be kept.
• Witnesses move, retire and forget. The coworker who heard a complaint or the administrator who received a report may be hard to find later.
• Insurance matters more than most survivors expect. Personal liability policies commonly exclude harm the insured intended to cause, so the abuser’s own coverage may not respond. The institution’s negligence coverage is often the realistic source of compensation, and identifying the policy years in force at the time of the abuse takes work.
• An abuser’s assets can be spent, hidden or transferred, and an organization can merge, reorganize or close.
• Treatment records, school records and counseling notes that show the injury and when it was understood are easier to gather close to the time.

Talking to a lawyer early is not the same as filing early. It lets someone preserve what can still be preserved while you decide what you want to do.

10When Should You Call a Lawyer About the Deadline?

Whenever you start to wonder whether it is too late, and before you decide that it is. The answer usually turns on your date of birth, the dates of the abuse, who the abuser was, which institution was involved, where it happened and what you knew when. Our sexual assault practice page at /sexual-assault/ explains how we approach these cases.

David Gregory of The Injury Counsel secured a $27 Million Verdict in a hotel assault case. Every case turns on its own facts, and a past result does not predict the outcome of any other case.
