The legal framework behind data breach class actions

Data breach class actions have exploded since 2015. Every major breach — Equifax, Target, Yahoo, T-Mobile, Anthem, Marriott — produces a multi-hundred-million-dollar class settlement.

How data breach class actions typically get certified and litigated

Standard damages structure: (a) baseline cash payment ($25-$400), (b) credit monitoring for 2-5 years, (c) reimbursement for documented losses (up to $5K-$25K), (d) undocumented time reimbursement at $10-$25/hr capped at 10-40 hours.

Recovery amounts and how to file

What triggers eligibility: your PII (Personally Identifiable Information) was in the breach. Notification letters usually go out, but not always to everyone affected. Settlement administrator sites let you search by email to confirm. Class Action Buddy indexes major breaches so you never miss a deadline.

What to do if you think you qualify

Class Action Buddy indexes data breach class actions regularly. When one covering your situation opens, you'll see it in our live settlements list with plenty of time before the filing deadline. Free users can file one settlement per month; Pro users get unlimited filings across all indexed cases.
