Article 1318 of the French Civil Code

If the debt arises from a matter that concerns only one of the joint and several debtors, that debtor alone is liable to the others. If he has paid it, he has no recourse against his co-debtors. If they have paid it, they have recourse against him.

Article 1318

Si la dette procède d’une affaire qui ne concerne que l’un des codébiteurs solidaires, celui-ci est seul tenu de la dette à l’égard des autres. S’il l’a payée, il ne dispose d’aucun recours contre ses codébiteurs. Si ceux-ci l’ont payée, ils disposent d’un recours contre lui.
