Oversecured creditor sought payment of its attorney's fees under 11 U.S.C. § 506(b), which allows such payment to oversecured creditors, as provided by their agreement with the debtor. The court determined that § 506(b) was an exception to the general "American rule" that parties must bear their own attorney's fees, and that such exceptions must be strictly construed. Creditor failed to provide a copy of its agreement with its proof of claim, as required by Bankruptcy Rule 3001, and again failed to provide it in response to debtor's objection to its attorney's fees claim. Without the agreement in the record, the court found that the application for attorney's fees under § 506(b) must be disallowed.
