Article 1474

Where it proves wholly or partially impossible to take recourse against a solidary debtor for an obligation referred to in the articles 1471 and 1473, the share which has proved to be irrecoverable is attributed to all his co-debtors in proportion to the share of the obligation that concerns each of them according to their mutual relationship.

Where the obligation was wholly or partially performed at the expense of a solidary debtor whom it did not concern, and where it proves impossible to take recourse against the co-debtors whom the obligation does not concern, the share which has proved to be irrecoverable is attributed to all the co-debtors whom it did not concern in proportion to the amounts for which each of them was liable towards the creditor at the time of performance of the obligation.

Each person involved in an attribution remains entitled to reclaim the amount which he has contributed from the person against whom it was impossible to take recourse.
