State Deadline Reminder

Most injury claims do not have one national filing deadline. A deadline may depend on state law, diagnosis date, discovery facts, exposure location, product-use history, wrongful-death status, and prior settlement or release paperwork.

Camp Lejeune is different from many open mass torts because the administrative filing window closed in August 2024. Other cases may still require state-by-state deadline review.

Use this page as an issue spotter, then review the case guide and relevant state guide for local context. The Roundup filing-deadline guide illustrates why an individual lawsuit deadline can differ from a proposed settlement schedule.

Camp Lejeune Water Contamination Claims

The Navy stopped accepting new Camp Lejeune Justice Act administrative claims after August 10, 2024. State personal-injury deadlines do not reopen that federal window. A timely administrative claim does not eliminate later deadlines following denial, court orders or settlement offers; the notice and individual claim history need separate review.
