Basic rule on solidarity

The settled rule is that when there is no agreement as to solidarity, the first and new debtors are considered to be jointly obligated.[1] This means that each of the debtors is liable only for a proportionate part of the debt. There is solidarity liability only when the obligation expressly so states, when the law so provides or when the nature of the obligation so requires.[2] This is because one who binds himself solidarity with the principal debtor acts as a surety and essentially "undertakes directly for the payment and is so responsible at once if the principal debtor makes default."[3]Under Article 1216 of the Civil Code, a creditor may proceed against any one of the solidary debtors or some or all of them simultaneously. Article 1217 further provides that payment by one of the solidary debtors extinguishes the obligation and he who made payment may claim from his co-debtors the share which corresponds to each.[4]
