Filing Deadline in South Dakota
South Dakota has a 3-year statute of limitations for product liability claims. Discovery rule may apply for latent injuries.
⚠️ 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.
