An “obligation” – refers to the juridical necessity to give, to do or not to do. (Article 1156, Civil Code)
The obligation is constituted upon the concurrence of these essential elements:
1) The vinculum juris or juridical tie which is the efficient cause established by the various sources of obligations (law, contracts, quasi-contracts, delicts and quasi-delicts);
2) The object which is the prestation or conduct, required to be observed (to give, to do or not to do); and
3) The subject-persons who, viewed from the demandability of the obligation, are the active (obligee) and the passive (obligor) subjects. (The Wellex Group, Inc. v. U-Land Airlines, Co., Ltd., G.R. No. 167519, 14 January 2015)
“Vinculum juris” – refers to the legal tie that creates a legal relationship between the parties resulting in rights and obligations against each other.
The “object” – refers to the conduct that is the subject of the obligation, such as the obligation to give, to do or not to do.
The object of an obligation may also be referred to as prestation in the context of contractual obligations.
The “active subject” – refers to the person who has the right to demand the performance of an obligation against another person.
The active subject may be a creditor or an obligee.
The “passive subject” – refers to the person who is under an obligation to give, to do or not to do, in favor of another person.
The passive subject may be a debtor or an obligor.
