12 C.F.R. § 51.4 – Claims.

(a) Submission of claims for consideration by the OCC.
1. (1) Persons who have claims against the receivership for an uninsured bank may present such claims, along with supporting documentation, for consideration by the OCC. The OCC will determine the validity and approve the amounts of such claims.
2. (2) The OCC will establish a date by which any person seeking to present a claim against the uninsured bank for consideration by the OCC must present their claim for determination. The deadline for filing such claims will not be less than 30 days after the end of the three-month notice period in § 51.3.
3. (3) The OCC will allow any claim against the uninsured bank received on or before the deadline for presenting claims if such claim is established to the OCC's satisfaction by the information on the uninsured bank's books and records or otherwise submitted. The OCC may disallow any portion of any claim by a creditor or claim of a security, preference, set-off, or priority which is not established to the satisfaction of the OCC.
(b) Submission of claims to a court. Persons with claims against an uninsured bank in receivership may present their claims to a court of competent jurisdiction for adjudication. Such persons must submit a copy of any final judgment received from the court to the OCC, to participate in ratable dividends along with other proved claims.
(c) Right of set-off. If a person with a claim against an uninsured bank in receivership also has an obligation owed to the bank, the claim and obligation will be set off against each other and only the net balance remaining after set-off shall be considered as a claim, provided such set-off is otherwise legally valid.
