Extra-contractual obligations

Every legal obligation must of necessity be extra-contractual or contractual. Extra-contractual obligation has its source in the breach or omission of those mutual duties which civilized society imposes upon its members, or which arise from these relations, other than contractual, of certain members of society to others, generally embraced in the concept of status. The legal rights of each member of society constitute the measure of the corresponding legal duties, mainly negative in character, which the existence of those rights imposes upon all other members of society. The breach of these general duties whether due to willful intent or to mere inattention, if productive of injury, gives rise to an obligation to indemnify the injured party. The fundamental distinction between obligations of this character and those which arise from contract rests upon the fact that, in cases of non-contractual obligation, it is the wrongful or negligent act or omission itself which creates the vinculum juris, whereas in contractual relations the vinculum exists independently of the breach of the voluntary duty assumed by the parties when entering into the contractual relation.
