An individual who is entitled to or is an applicant for a benefit under this subchapter, subchapter VIII, or subchapter XVI, who has attained 18 years of age or is an emancipated minor, may, at any time, designate one or more other individuals to serve as a representative payee for such individual in the event that the Commissioner of Social Security determines under subparagraph (A) that the interest of such individual would be served by certification for payment of such benefits to which the individual is entitled to a representative payee. If the Commissioner of Social Security makes such a determination with respect to such individual at any time after such designation has been made, the Commissioner shall—
(I)#
certify payment of such benefits to the designated individual, subject to the requirements of paragraph (2); or
(II)#
if the Commissioner determines that certification for payment of such benefits to the designated individual would not satisfy the requirements of paragraph (2), that the designated individual is unwilling or unable to serve as representative payee, or that other good cause exists, certify payment of such benefits to another individual or organization, in accordance with paragraph (1).
