Form B 410: Proof Of Claim

Form B 410, printed as Official Form 410, Proof of Claim, is the Official Bankruptcy Form the form describes as being for making a claim for payment in a bankruptcy case. The current version is dated 04/25. The U.S. Courts page lists it under Bankruptcy Forms, effective on December 1, 2024 and updated on April 1, 2025, says it is derived from Official Form 10, and says Official Bankruptcy Forms are approved by the Judicial Conference and must be used under Bankruptcy Rule 9009. The committee note says Form 410 applies in all cases.

The 3-page form identifies the claim and the creditor, gives the amount and basis of the claim as of the date the case was filed, asks whether it is secured, based on a lease, subject to setoff or entitled to priority, and ends with a signature under penalty of perjury. The form says not to use it for a request for payment of an administrative expense, which is made according to 11 U.S.C. § 503.

This page explains the form in plain words and is not legal advice. The instructions suggest considering the advice of an attorney. You can fill it out free in your browser on this page and download the result without an account.
