Code of Civil Procedure Article 515
A payment order shall cease to be operative if it cannot be served upon the debtor within three months after it is issued. In cases as provided in the preceding paragraph, where the court has issued a final-and-binding order certificate in error, and where such a certificate is revoked within five years, starting from the date recorded on the certificate, the court should notify the creditor of such an action. If the creditor initiates an action within the 20-day peremptory period after the notification is received, it is deemed that an action has been initiated when the motion for a payment order is filed; the same principle shall apply to the event when the action is initiated before the receipt of the notification.In cases as provided in the preceding paragraph, the costs for demand proceedings shall be included as a part of litigation costs or mediation procedure costs.
