11 U.S.C. § 509 - Claims of codebtors

Text

(a) Except as provided in subsection (b) or (c) of this section, an entity that is liable with the debtor on, or that has secured, a claim of a creditor against the debtor, and that pays such claim, is subrogated to the rights of such creditor to the extent of such payment.

(b) Such entity is not subrogated to the rights of such creditor to the extent that—

(1) a claim of such entity for reimbursement or contribution on account of such payment of such creditor’s claim is—

(A) allowed under section 502 of this title;

(B) disallowed other than under section 502(e) of this title; or

(C) subordinated under section 510 of this title; or

(2) as between the debtor and such entity, such entity received the consideration for the claim held by such creditor.

(c) The court shall subordinate to the claim of a creditor and for the benefit of such creditor an allowed claim, by way of subrogation under this section, or for reimbursement or contribution, of an entity that is liable with the debtor on, or that has secured, such creditor’s claim, until such creditor’s claim is paid in full, either through payments under this title or otherwise.

Notes

Historical and Revision Notes

legislative statementsSection 509 of the House amendment represents a substantial revision of provisions contained in H.R. 8200 as passed by the House and in the Senate amendment. Section 509(a) states a general rule that a surety or co-debtor is subrogated to the rights of a creditor assured by the surety or co-debtor to the extent the surety or co-debtor pays such creditor. Section 509(b) states a general exception indicating that subrogation is not granted to the extent that a claim of a surety or co-debtor for reimbursement or contribution is allowed under section 502 or disallowed other than under section 502(e). Additionally, section 509(b)(1)(C) provides that such claims for subrogation are subordinated to the extent that a claim of the surety or co-debtor for reimbursement or contribution is subordinated under section 510(a)(1) or 510(b). Section 509(b)(2) reiterates the well-known rule that prevents a debtor that is ultimately liable on the debt from recovering from a surety or a co-debtor. Although the language in section 509(b)(2) focuses in terms of receipt of consideration, legislative history appearing elsewhere indicates that an agreement to share liabilities should prevail over an agreement to share profits throughout title 11. This is particularly important in the context of co-debtors who are partners. Section 509(c) subordinates the claim of a surety or co-debtor to the claim of an assured creditor until the creditor’s claim is paid in full.

senate report no. 95–989Section 509 deals with codebtors generally, and is in addition to the disallowance provision in section 502(e). This section is based on the notion that the only rights available to a surety, guarantor, or comaker are contribution, reimbursement, and subrogation. The right that applies in a particular situation will depend on the agreement between the debtor and the codebtor, and on whether and how payment was made by the codebtor to the creditor. The claim of a surety or codebtor for contribution or reimbursement is discharged even if the claim is never filed, as is any claim for subrogation even if the surety or codebtor chooses to file a claim for contribution or reimbursement instead. Subsection (a) subrogates the codebtor (whether as a codebtor, surety, or guarantor) to the rights of the creditor, to the extent of any payment made by the codebtor to the creditor. Whether the creditor’s claim was filed under section 501(a) or 501(b) is irrelevant. The right of subrogation will exist even if the primary creditor’s claim is allowed by virtue of being listed under proposed 11 U.S.C. 924 or 1111, and not by reason of a proof of claim. Subsection (b) permits a subrogated codebtor to receive payments in the bankruptcy case only if the creditor has been paid in full, either through payments under the bankruptcy code or otherwise.
