What is Benefit Of Division?

Legal Definition
In the civil law, which, in this respect, has been adopted in Louisiana, although, when there are several sureties, each one is bound for the whole debt, yet when one of them is sued alone, he has a right to have the debt apportioned among all the solvent sureties on the same obligation, so that he shall be compelled to pay his own share only. This is called the benefit of division. Civil Code of Lo. art. 3014 to 3020. See 2 Bouv. Inst. n. 1414.
