Section 1506.11 - May I request a review of the existence or amount of a claim?(a) USADF shall provide the debtor with a reasonable opportunity for an internal review of the existence or amount of the debt. For offset of current Federal salary under 5 U.S.C. 5514 , a debtor may also request a hearing. (See subpart C of this part).(b) A request for a review must be submitted in writing to the appropriate contact office by the payment due date indicated in the Bill for Collection or demand letter. The request must state the basis for the debtor's dispute of the claim and include any relevant documentation in support.(1) USADF will provide for an internal review of the debt by an appropriate official. The review may include examination of documents, internal discussions with relevant officials and discussions with the debtor, at USADF's discretion.(2) An oral hearing is not required when USADF determines that the matter can be decided on the documentary record. When an oral hearing is not required, USADF shall accord the debtor a "paper hearing," that is, a determination of the request for reconsideration based upon a review of the written record.(3) Unless otherwise required by law, an oral hearing under this section is not required to be a formal evidentiary hearing, although USADF will carefully document all significant matters discussed at the hearing.
