Missouri's product liability statute of limitations is governed by the state's civil procedure and limitations statutes.

Under state law, the limitations period is tolled for minor claimants until they reach age 21.

About This Calculator
This calculator finds your exact filing deadline for a product liability claim in Missouri. It applies Missouri's specific statute of limitations period, checks whether the discovery rule extends your deadline, accounts for tolling if the injured party was a minor, and flags any special notice requirements if your claim involves a government entity. Enter your incident date — or discovery date if the harm wasn't immediately apparent — and the calculator counts forward using Missouri's exact rule to show your filing deadline, the time remaining, and an urgency status. Results are based on verified state statute citations, not general estimates.
What is a Product Liability Claim?
Statute of Limitations Deadline Calculation Formula
Here is how the calculation methodology works using representative illustrative figures (hypothetical example only — see Missouri's actual deadlines in the sections above):
- Incident Date: June 1, 2024
- Statutory Period: 2 years (730 days)
- Discovery Date (if delayed discovery applies): September 1, 2024
- Standard Filing Deadline: June 1, 2026 (2 years from incident)
- Discovery-Extended Deadline: September 1, 2026 (2 years from discovery)
How Missouri's Product Liability Deadline Works
Under Missouri Rev. Stat. § 71, Missouri provides 5 years to file a product liability lawsuit. The clock typically begins when the injury was discovered — or when it reasonably should have been discovered — rather than on the date the harm occurred. This is known as the discovery rule. Missouri extends the filing window by up to 1 additional year under the discovery rule.
Missouri's product liability statute of limitations is governed by the state's civil procedure and limitations statutes. Claims against state agencies, municipalities, or other government entities in Missouri may require filing a formal notice of claim before suit can be commenced — notice deadlines vary by entity type and are often shorter than the civil filing deadline. Under state law, the limitations period is tolled for minor claimants until they reach age 21.
Special Circumstances
Government entity claims: If the defendant is a government entity, Missouri requires a formal administrative claim notice to be filed within 6 months of the incident before a lawsuit may be filed. Missing this notice deadline permanently bars the claim. After the claim is rejected, you have 12 months to file suit.
Minor claimants: If the injured person was a minor at the time of the incident, Missouri tolls the statute of limitations until they reach age 21.
What Happens If You Miss the Deadline
If a lawsuit is filed after the statute of limitations expires, the defendant can ask the court to dismiss the case as time-barred — and courts almost always grant this motion, regardless of how strong the underlying claim is. The right to sue is lost permanently; there is no general exception for not knowing the deadline existed. A small number of circumstances can pause or extend the clock, covered in the Special Circumstances section above if they apply to your claim type and state. If your deadline is approaching or may have already passed, contact a licensed attorney immediately — some exceptions are themselves time-sensitive.
Frequently Asked Questions
How does Missouri determine when the clock starts for a product liability claim?
Under RSMo § 516.120, Missouri applies its general 5-year statute of limitations to product liability claims, utilizing a robust discovery rule. The clock does not begin when the defective product is purchased, but rather when the injury is sustained and is capable of ascertainment. This protects victims of latent harms, such as toxic exposure or defective implants.
Does Missouri impose a statute of repose on product liability claims?
Missouri does not have a general, absolute statute of repose for product liability claims. While it does enforce a statute of repose for medical malpractice and improvements to real property, standard defective consumer goods and machinery are governed by the discovery-based statute of limitations, allowing claims to proceed regardless of the product's age.
What are the rules for minor tolling in Missouri product cases?
Under RSMo § 516.170, Missouri tolls the product liability statute of limitations for minors until they reach the age of 21. Because product liability falls under the general § 516.120 statute of limitations, this extended disability tolling applies, completely distinct from the restrictive age-18 tolling found in Missouri medical malpractice law. This ensures young victims have maximum protection.
Do different product defect theories carry different deadlines in Missouri?
Whether a plaintiff alleges a design defect, a manufacturing flaw, or a failure to warn under Missouri strict liability laws, the claims generally fall under the same overarching 5-year statute of limitations. The critical factor for the deadline is usually not the specific theory plead, but rather when the plaintiff's physical injury became capable of ascertainment.
How does a UCC warranty claim differ from a tort claim in Missouri?
A plaintiff suing over a defective product in Missouri may also assert a breach of implied warranty under the Uniform Commercial Code. This UCC claim operates on a strictly separate timeline that accrues when the product is delivered to the buyer. Unlike the tort claim under § 516.120, the warranty clock starts ticking immediately, regardless of when the injury happens.
