In case of default by the
employer in the payment of
compensation due under any award of
compensation for a period of thirty days after the
compensation is due and payable, the
person to whom such
compensation is payable may, within one year after such default, make application to the
deputy commissioner making the
compensation order or a supplementary order declaring the amount of the default. After investigation, notice, and hearing, as provided in
section 919 of this title, the
deputy commissioner shall make a supplementary order, declaring the amount of the default, which shall be filed in the same manner as the
compensation order. In case the payment in default is an installment of the award, the
deputy commissioner may, in his discretion, declare the whole of the award as the amount in default. The applicant may file a certified copy of such supplementary order with the clerk of the Federal district court for the judicial district in which the
employer has his principal place of business or maintains an office, or for the judicial district in which the
injury occurred. In case such principal place of business or office or place where the
injury occurred is in the District of Columbia, a copy of such supplementary order may be filed with the clerk of the
United States District Court for the District of Columbia. Such supplementary order of the
deputy commissioner shall be final, and the court shall, upon the filing of the copy, enter judgment for the amount declared in default by the supplementary order if such supplementary order is in accordance with law. Review of the judgment so entered may be had as in civil suits for damages at common law. Final proceedings to execute the judgment may be had by writ of execution in the form used by the court in suits at common law in actions of assumpsit. No fee shall be required for filing the supplementary order nor for entry of judgment thereon, and the applicant shall not be liable for costs in a proceeding for review of the judgment unless the court shall otherwise direct. The court shall modify such judgment to conform to any later
compensation order upon presentation of a certified copy thereof to the court.
