Article 1221

If the thing has been lost or if the prestation has become impossible without the fault of the solidary debtors, the obligation shall be extinguished.

If there was fault on the part of any one of them, all shall be responsible to the creditor, for the price and the payment of damages and interest, without prejudice to their action against the guilty or negligent debtor.

If through a fortuitous event, the thing is lost or the performance has become impossible after one of the solidary debtors has incurred in delay through the judicial or extrajudicial demand upon him by the creditor, the provisions of the preceding paragraph shall apply. (1147a)
