553. A defendant being sued under Book II may request that the case be heard under this Title provided the defendant would qualify to act as plaintiff under this Title. The same request may be made when the application is based on a claim assigned to a third person in return for payment provided the defendant would qualify to act as plaintiff under this Title.
The request is presented to the clerk of the court seized of the matter, at any time before the case is set down for trial and judgment. If the request is found to be admissible, the court clerk notifies the decision to the plaintiff and the latter may, within 15 days after the notification, ask for a review of the decision by the court seized of the application. In the absence of a review, the court clerk transfers the record so that the case may be continued under this Title.
