Filing Deadline in Missouri
Missouri has a 5-year statute of limitations for product liability claims. Unlike many states, Missouri uses an occurrence rule (clock starts at time of injury, not discovery). Consulting an attorney promptly is important.
⚠️ Important: Many women who used hair relaxers didn't connect their cancer diagnosis to product use until after the NIH Sister Study was published in October 2022. Under the discovery rule, your deadline may start from when you discovered (or should have discovered) this connection. Do not assume you've missed your deadline — consult an attorney first.
