Compensation must be requested from the investigating or trial court before it rules on the public prosecution.
The application shall be the subject of a request dated and signed by the applicant or his lawyer, addressed to the court either by registered letter with acknowledgement of receipt, or by delivery to the clerk’s office against receipt:
1° At the latest before the expiry of the twenty-day period provided for by Article 175, if the request is made before the examining magistrate or the investigating chamber;
2° Before the close of the hearing, if the request is made before a trial court.
This request shall indicate the amount of compensation claimed for each of the costs incurred, in accordance with the distinctions provided for by Article R. 249-2. It is accompanied by supporting documents for the costs incurred, including in particular a certificate from the lawyer stating either the amount of his fees or the fact that these exceeded the amount provided for in the first paragraph of the same article. Where the compensation claimed also relates to the costs provided for in the last paragraph of article R. 249-2, the supporting documents shall also include a certificate from the provisional beneficiary stating either the amount of his fees or that they exceeded the amounts provided for in the last paragraph of that article.
