Mass Tort Lawsuits in California
CAA guide for California residents researching major mass tort and injury lawsuits: each case's current status, how California filing deadlines work, the federal courts involved, and links to California-specific guides for each case.

How long do California residents have to file a lawsuit?
California's general personal injury statute of limitations is 2 years (Cal. Code Civ. Proc. § 335.1). Product liability and toxic exposure claims do not always follow the general rule, so the deadline that controls a specific case can be shorter or longer.
- General personal injury 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, and how a claim is filed, only a licensed attorney can confirm the deadline for a specific situation. Federal multidistrict litigation can also change where and how a California claim proceeds.
Which federal courts handle California mass tort cases?
Mass tort claims by California residents are frequently filed in federal court and transferred into multidistrict litigation in other districts. The federal district courts covering California are:
- Northern District of California
- Eastern District of California
- Central District of California
- Southern District of California
Living in California does not mean a case is filed only in California. Many claims are coordinated nationally, but California law can still affect deadlines, damages, and wrongful-death rules.
