The subject matter of the dispute shall be determined by the respective claims of the parties as set out in the application provided for in Article 1560.
The parties may not amend their claims other than to update the amount of a claim relating to a claim for successive performance, to oppose a subsequent payment or set-off or to have questions arising from the intervention of a third party or from the occurrence or revelation of a fact subsequent to the establishment of the agreement determined.
The parties may only change the legal basis of their claim or raise new pleas in law in order to respond to the judge’s invitation to provide the explanations of fact or law that he deems necessary for the resolution of the dispute.
