Depo-Provera Lawsuit in California

What California residents should know

California residents are not necessarily limited to filing only in California state court. Many mass tort claims may be evaluated by national firms, filed in federal court, coordinated through MDL proceedings, or handled through another legal process.

State law may still matter for deadlines, damages, claim evaluation, and certain procedural issues.

California's coordinated state-court Depo-Provera cases

California is the only one of these states with a formal coordinated state-court proceeding for Depo-Provera. California state-court cases have been organized into a Judicial Council Coordination Proceeding (JCCP) in Alameda County Superior Court, which runs in parallel with the federal MDL and whose judge takes part in joint status conferences with the federal court. California residents who file in federal court instead are transferred into MDL No. 3140 in the Northern District of Florida; as of a March 2026 federal status report, dozens of California state-court cases were pending.

What is the filing deadline for Depo-Provera lawsuits in California?

For a California resident researching Depo-Provera claims, the starting point is usually California's general personal injury period: 2 years under Cal. Code Civ. Proc. § 335.1. That is only a starting point, not a final legal deadline for every person.

The real filing deadline can depend on diagnosis date, when the injury and possible cause were discovered, exposure location, wrongful-death issues, prior claim paperwork, and whether the case is filed directly, transferred to an MDL, or handled through another process.

Discovery-rule note: California applies a discovery rule: the period generally runs from when a plaintiff discovers, or reasonably should have discovered, the injury and its wrongful cause.

How long do California residents have to file?

California's personal injury statute of limitations applicable to product liability claims is 2 years (Cal. Code Civ. Proc. § 335.1). Accrual timing, tolling, and repose periods can still change the real deadline in an individual case.

• Filing period: 2 years — Cal. Code Civ. Proc. § 335.1.
• Discovery rule: California applies a discovery rule: the period generally runs from when a plaintiff discovers, or reasonably should have discovered, the injury and its wrongful cause.

Because the controlling deadline depends on diagnosis date, discovery facts, exposure history, wrongful-death rules, and how the claim is filed, only a licensed attorney can confirm the deadline that applies to a specific situation. This page is general legal information, not legal advice.
