(a) In any case in which the employer or insurance carrier is in
default in the payment of compensation due under any award of
compensation, for a period of 30 days after the compensation is due and
payable, the person to whom such compensation is payable may, within 1
year after such default, apply in writing to the district director for a
supplementary compensation order declaring the amount of the default.
Upon receipt of such application, the district director shall institute
proceedings with respect to such application as if such application were
an original claim for compensation, and the matter shall be disposed of
as provided for in Sec. 702.315, or if agreement on the issue is not
reached, then as in Sec. 702.316 et seq.
(b) If, after disposition of the application as provided for in
paragraph (a) of this section, a supplementary compensation order is
entered declaring the amount of the default, which amount may be the
whole of the award notwithstanding that only one or more installments is
in default, a copy of such supplementary order shall be forthwith sent
by certified mail to each of the parties and their representatives.
Thereafter, the applicant may obtain and file with the clerk of the
Federal district court for the judicial district where the injury
occurred or the district in which the employed has his principal place
of business or maintains an office, a certified copy of said order and
may seek enforcement thereof as provided for by section 18 of the Act,
33 U.S.C. 918.
