28 C.F.R. § 104.81 Limitation on attorney fees.
(a) In general—(1) In general. Notwithstanding any contract, the representative of an individual may not charge, for services rendered in connection with the claim of an individual under this title, including expenses routinely incurred in the course of providing legal services, more than 10 percent of an award paid under this title on such claim. Expenses incurred in connection with the claim of an individual in this title other than those that are routinely incurred in the course of providing legal services may be charged to a claimant only if they have been approved by the Special Master.
(2) Certification. In the case of any claim in connection with which services covered by this section were rendered, the representative shall certify his or her compliance with this section and shall provide such information as the Special Master requires to ensure such compliance.
(b) Limitation—(1) In general. Except as provided in paragraph (b)(2) of this section, in the case of an individual who was charged a legal fee in connection with the settlement of a civil action described in section 405(c)(3)(C)(iii) of the Act, the representative who charged such legal fee may not charge any amount for compensation for services rendered in connection with a claim filed by or on behalf of that individual under this title.
(2) Exception. If the legal fee charged in connection with the settlement of a civil action described in section 405(c)(3)(C)(iii) of the Act of an individual is less than 10 percent of the aggregate amount of compensation awarded to such individual through such settlement, the representative who charged such legal fee to that individual may charge an amount for compensation for services rendered to the extent that such amount charged is not more than Ten (10) percent of such aggregate amount through the settlement, minus the total amount of all legal fees charged for services rendered in connection with such settlement.
(c) Discretion to lower fee. In the event that the Special Master finds that the fee limit set by paragraph (a) or (b) of this section provides excessive compensation for services rendered in connection with such claim, the Special Master may, in the discretion of the Special Master, award as reasonable compensation for services rendered an amount lesser than that permitted for in paragraph (a) of this section.
