34 C.F.R. § 681.40
(a) A lender or holder must file an insurance claim on a form approved by the Secretary. The lender or holder must attach to the claim all documentation necessary to litigate a default, including any documents required to be submitted by the Federal Claims Collection Standards, and which the Secretary may require. Failure to submit the required documentation and to comply with the HEAL statute and regulations or the lender's or holder's insurance contract will result in a claim not being honored. The Secretary may deny a claim that is not filed within the period specified in this section. The Secretary requires for all claims at least the following documentation:
(c) In addition, the lender or holder must comply with the following requirements for the filing of default, death, disability, and bankruptcy claims:
(1) Default claims. Default means the persistent failure of the borrower to make a payment when due or to comply with other terms of the note or other written agreement evidencing a loan under circumstances where the Secretary finds it reasonable to conclude that the borrower no longer intends to honor the obligation to repay the loan. In the case of a loan repayable (or on which interest is payable) in monthly installments, this failure must have persisted for 120 days. In the case of a loan repayable (or on which interest is payable) in less frequent installments, this failure must have persisted for 180 days. If, for a particular loan, an automatic stay is imposed on collection activities by a Bankruptcy Court, and the lender or holder receives written notification of the automatic stay prior to initiating legal proceedings against the borrower, the 120- or 180-day period does not include any period prior to the end of the automatic stay.
(iii) In addition to the documentation required for all claims, the lender or holder must submit with its default claim at least the following:
(4) Bankruptcy claims. For a bankruptcy under chapter 11 or 13 of the Bankruptcy Act, or a bankruptcy under chapter 7 of the Bankruptcy Act when the borrower files a complaint to determine the dischargeability of the HEAL loan, the current holder must file a claim with the Secretary within 10 days of the initial date of receipt of court notice or written notice from the borrower's attorney that the borrower has filed for bankruptcy under chapter 11 or chapter 13, or has filed a complaint to determine the dischargeability of the HEAL loan under chapter 7. The initial date of receipt of the written notice must be documented by a date stamp. The lender or holder must file with the bankruptcy court a proof of claim, if applicable, and an objection to the discharge or compromise of the HEAL loan. In addition to the documentation required for all claims, with its claim the lender or holder must submit to the Secretary at least the following:
(ix) In cases where there is defective service due to the borrower's failure to list the proper creditor, a copy of the letter sent to the borrower at the time of purchase of the HEAL loan by the current holder, or a sample letter with documentation indicating when the letter was sent to the borrower.
