La. Civ. Code art. 3057
Current with changes from the 2024 Legislative Session
A surety who pays the creditor more than his share may recover the excess from his co-sureties in proportion to the amount of the obligation each is to bear as to him. If a surety obtains the conventional discharge of other co-sureties by paying the creditor, any reduction in the amount owed by those released benefits them proportionately.
