Mass Tort Liability Claims: What Deadlines Apply Before Year’s End?

The deadlines still open before year's end are November 13 for eligible AFFF personal-injury identification, November 30 for Depo-Provera settlement registration, and December 22 for public water system exclusions from four PFAS settlements. Consumers in the generic-drug end-payer settlement faced a November 9 claim deadline with no payment for late claims. A mass tort lets many people with related injury claims pursue individual cases in coordinated proceedings. An MDL, or multidistrict litigation, moves those federal cases to one court for pretrial work while each claim stays separate.

What must Depo-Provera claimants finish by November 30?

Depo-Provera claimants in MDL 3140 must register for the settlement program by November 30, 2026, with BrownGreer as administrator. The U.S. District Court for the Northern District of Florida set that cutoff in the settlement registration order. Claimants found ineligible are identified to the court afterward.

Counsel must also submit a compliant complaint to BrownGreer for each registered client by the same date. That duty comes from the administrative-docket order, described in the King Law copy of CMO No. 18 issued September 15, 2026. Registration alone does not complete the file without that complaint submission.

What must AFFF injury claimants do by November 13?

Eligible personal-injury claimants under the 3M settlement must be identified to the MDL 2873 court through the portal by November 13, 2026. MDL 2873 set that identification cutoff in the order for eligible personal-injury claimants.

This step applies only to claimants who qualify under the 3M agreement. It is an identification to the court, not a finding about payment amount. Missing the portal cutoff can leave an otherwise eligible claim outside the settlement process.

What must water systems decide by December 22?

U.S. public water systems in the AFFF litigation must request exclusion from four proposed PFAS settlements by December 22, 2026, or remain in the classes. The court-authorized settlement notice describes the group as four settlements totaling more than $149 million in the notice to public water systems.

The official PFAS Water Settlement site, run by the settlement administrator, lists the same December 22, 2026 exclusion-request date for the Carrier, Archroma, Nation Ford and Amerex settlements. Staying in means accepting the class outcome. Excluding preserves a separate path but requires timely written action.

Which deadlines already closed, and why file early?

Consumers who paid for covered generic drugs from May 1, 2009 to December 31, 2019 had to submit or postmark the end-payer claim by November 9, 2026. Techlicious reporting on the official instructions states that late claims receive no payment. No new Camp Lejeune administrative claim can meet a year-end deadline.

Motley Rice reports that the two-year Camp Lejeune Justice Act window closed August 10, 2024, and the Navy stopped accepting filings. MDL consolidation also does not pause individual statutes of limitations, which commonly run one to three years, so each plaintiff still needs a timely complaint. A JAMS/Sidley analysis citing Judicial Panel data reports more than 205,000 MDL cases pending in August 2026. Coordination does not protect an unfiled claim from a state deadline.
