If a creditor has a claim against several debtors who are liable for the same claim, and one of the debtors has already satisfied the claim in whole or in part, the law governing the debtor's obligation towards the creditor also governs the debtor's right to claim recourse from the other debtors. The other debtors may rely on the defences they had against the creditor to the extent allowed by the law governing their obligations towards the creditor.
