1. A joint and several debtor who has performed the debt shall have a right of recourse against any of the others for their respective share. If one of them is bankrupt or insolvent, the performing debtor and the solvent joint and several debtors shall bear the burden of such bankruptcy or insolvency, each in proportion to their share, without prejudice to their right of recourse against the bankrupt or insolvent debtor upon their solvency. 2. The debt, if performed by one of the joint and several debtors, shall be divided into equal shares among all, unless the law or the agreement provides otherwise.
