42 C.F.R. § 60.17 Security and endorsement.
Title 42 - Public Health
(a) A HEAL loan must be made without security. (b) With one exception, it must also be made without endorsement. If a borrower is a minor and cannot under State law create a legally binding obligation by his or her own signature, a lender may require an endorsement by another person on the borrower's HEAL note. For purposes of this paragraph, an “endorsement” means a signature of anyone other than the borrower who is to assume either primary or secondary liability on the note.
