Important dates
How hard is this claim to file?
What the form asks
- — The notice ID printed on the settlement notice mailed to you by the settlement administrator. (On the notification letter / settlement notice you received from Cornerstone.)
- — Choose one: documented losses reimbursement, credit monitoring (SSN Subclass only), or pro rata cash payment. (Determined by your own situation and subclass membership.)
- — Receipts, bank statements, or other non-self-prepared records showing out-of-pocket expenses traceable to the data incident, plus a description of how each expense relates to the incident. (Your own financial records, bank, credit card statements.)
- — Choose either a paper check mailed to the address you provide, or a credit monitoring activation code (SSN Subclass). (Personal preference; select on the claim form.)
Documents you'll need
Watch out for
- This settlement is now past its claims deadline — filing is no longer possible unless a court extension was granted; verify the current status at the settlement website before attempting to file.
- Pro rata cash payments are not a fixed amount; the exact payment depends on the number of valid claims submitted and funds remaining after other costs are paid.
- Documented loss claims require non-self-prepared documentation — self-prepared notes or statements are not accepted.
- SSN Subclass members can claim extraordinary losses (such as identity theft costs), but only after exhausting all available credit monitoring and identity theft insurance.
We prepare — you file on the official site yourself. This is not legal advice and is not an eligibility decision; the administrator and court decide.
