(1) The amount of the costs and expenses which a person involved must reimburse to another person is assessed by the administrative authority upon request. It is stated upon request that interest is payable on the assessed costs and expenses in accordance with section 104 (1) sentence 2 of the Code of Civil Procedure from the date when the request for assessment is submitted. A calculation of costs which were incurred by the applicant, one information duplicate to the other person concerned, and the receipts to verify the individually assessed amounts, are to be enclosed with the request for assessment. For taking an assessed amount into consideration, it is sufficient that it has been made credible. With regard to the expenses incurred by an attorney, such as postal and telecommunications services, the statement of the attorney that the expenses have been incurred is sufficient.
(2) The provisions of the Code of Civil Procedure concerning the coercive enforcement of costs decisions apply accordingly to the enforcement of a decision on administrative costs. Coercive enforcement is permitted only if the administrative costs decision has become incontestable. The executable copy is issued by the record officer of the office of the court with jurisdiction in accordance with section 68.
