Mass Tort Lawsuits in Ohio
OHA guide for Ohio residents researching major mass tort and injury lawsuits: each case's current status, how Ohio filing deadlines work, the federal courts involved, and links to Ohio-specific guides for each case. Status varies by case — some remain in active intake, while others (such as Camp Lejeune Justice Act claims) have closed filing windows, as each guide notes.

How long do Ohio residents have to file a lawsuit?
Ohio's general personal injury statute of limitations is 2 years (Ohio Rev. Code § 2305.10). 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 — Ohio Rev. Code § 2305.10.
- Discovery rule: Ohio's statute includes discovery-based accrual provisions for certain exposure-related claims.
- Statute of repose: Ohio applies a 10-year statute of repose to many product liability claims (§ 2305.10(C)).
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 Ohio claim proceeds.
Which federal courts handle Ohio mass tort cases?
Mass tort claims by Ohio residents are frequently filed in federal court and transferred into multidistrict litigation in other districts. The federal district courts covering Ohio are:
- Northern District of Ohio
- Southern District of Ohio
Living in Ohio does not mean a case is filed only in Ohio. Many claims are coordinated nationally, but Ohio law can still affect deadlines, damages, and wrongful-death rules.
