((a)) ** .—** A fiduciary may not collect a fee from a beneficiary for any month with respect to which the Secretary or a court of competent jurisdiction has determined that the fiduciary misused all or part of the individual’s benefit, and any amount so collected by the fiduciary as a fee for such month shall be treated as a misused part of the individual’s benefit.
((b)) ** .—** For purposes of this chapter, misuse of benefits by a fiduciary occurs in any case in which the fiduciary receives payment, under any of laws administered by the Secretary, for the use and benefit of a beneficiary and uses such payment, or any part thereof, for a use other than for the use and benefit of such beneficiary or that beneficiary’s dependents. Retention by a fiduciary of an amount of a benefit payment as a fiduciary fee or commission, or as attorney’s fees (including expenses) and court costs, if authorized by the Secretary or a court of competent jurisdiction, shall be considered to be for the use or benefit of such beneficiary.
