D.C. Code § 20-751: Compensation.

Except as may otherwise be ordered by the Court for good cause shown in respect to a supervised personal representative or a special administrator, a personal representative is entitled to reasonable compensation for services. If a will provides for compensation of the personal representative and there is no contract with the decedent regarding compensation, the personal representative may renounce the provision either before or after qualifying and be entitled to reasonable compensation. A personal representative also may renounce the right to all or any part of the compensation. A written renunciation of fee may be filed with the Court.
