RA 386 (Civil Code of the Philippines) Article 1207

Article 1207

ART. 1207. The concurrence of two or more creditors or of two or more debtors in one and the same obligation does not imply that each one of the former has a right to demand, or that each one of the latter is bound to render, entire compliance with the prestation. There is a solidary liability only when the obligation expressly so states, or when the law or the nature of the obligation requires solidarity. (1137a)
