A debt is not legally enforceable for purposes of mandatory transfer to BFS if it is the subject of a pending administrative review process required by statute or regulation and collection action during the review process is prohibited.(b) Except as set forth in paragraph (a) of this section, USADF will transfer any debt covered by this part that is more than 180 days delinquent to BFS for debt collection services.
