Cause of contracts

Cause (causa) is the essential or more proximate purpose or reason
which the contracting parties have in view at the time of entering into
the contract,[1] or, as expressed in another case, it is the “why of the contract,
the essential reason which moves the contracting parties to enter into
the contract.’’[2] It is the Civil Code term for consideration in Anglo-American or
common law.[3]
ART. 1350. In onerous contracts the cause is understood to be, for each contracting party, the prestation or promise of a thing or service by the other; in remuneratory ones, the service or benefit which is remunerated; and in contracts of pure beneficence, the mere liberality of the benefactor. (1274)
