Article R322-27 of the French Code of civil enforcement procedures
On the specified date, the pursuing creditor or, failing this, any registered creditor, who is then subrogated to the proceedings, requests the sale. If no creditor requests the sale, the court declares that the summons to pay serving as a seizure has lapsed. In this case, the defaulting creditor retains all the costs of the seizure unless the court decides otherwise, giving its reasons.
