What are the key deadlines for filing a product liability lawsuit?

On Behalf of | Jan 20, 2026 | Injuries

If you suffer harm from a defective product, timing shapes your legal options. Missouri law sets firm deadlines that control whether a claim can move forward. Understanding these time limits helps you protect your rights and avoid losing a valid claim.

Missouri’s statute of limitations for product liability

Missouri applies a five-year statute of limitations to most product liability lawsuits. The deadline generally begins when the injury becomes capable of being ascertained, meaning when you knew or reasonably should have known that the product caused harm. If you file after the five-year period expires, the court can dismiss the claim even if the defect is clear.

How Missouri determines when a claim begins

Some product-related injuries do not show immediate symptoms, which affects when the filing period starts. Missouri courts focus on when a reasonable person would connect the injury to the product, not necessarily the purchase date. This approach allows some flexibility, but it still places responsibility on you to act once the connection becomes clear.

Why Missouri does not apply a general statute of repose

Missouri does not impose a broad statute of repose that cuts off all product liability claims after a set number of years. Unlike some states, Missouri relies on the statute of limitations rather than a fixed outer deadline tied to the product’s sale date. This distinction matters for injuries linked to long-lasting or delayed-effect products.

Limited exceptions that can affect deadlines

Certain circumstances can alter how deadlines apply. When the injured person is a minor, Missouri law may delay the start of the limitations period. Claims involving concealment or misrepresentation may also shift when the clock begins, while cases involving public entities can include shorter notice requirements.

Acting early helps preserve your claim

Waiting to act can weaken a product liability claim even when the filing deadline remains open. Evidence can disappear, products can change hands, and witnesses may forget details. Moving early helps preserve proof and allows time to identify manufacturers, distributors, and sellers who may share responsibility.
