Elements of a Contract & Perfection Thereof

A contract is defined as a juridical convention manifested in legal form, by virtue of which one or more persons bind themselves in favor of another, or others, or reciprocally, to the fulfillment of a prestation to give, to do, or not to do. There can be no contract unless the following concur: (a) consent of the contracting parties; (b) object certain which is the subject matter of the contract; (c) cause of the obligation which is established.

Specifically, by the contract of sale, one of the contracting parties obligates himself to transfer ownership of and to deliver a determinate thing and the other party to pay therefor a price certain in money or its equivalent.

The essential requisites of a valid contract of sale are:

[1] Consent of the contracting parties by virtue of which the vendor obligates himself to transfer ownership of and to deliver a determinate thing, and the vendee obligates himself to pay therefor a price certain in money or its equivalent.
[2] Object certain which is the subject matter of the contract. The object must be licit and at the same time determinate or, at least, capable of being made determinate without the necessity of a new or further agreement between the parties.
[3] Cause of the obligation which is established. The cause as far as the vendor is concerned is the acquisition of the price certain in money or its equivalent, which the cause as far as the vendee is concerned is the acquisition of the thing which is the object of the contract.
Contracts of sale are perfected by mere consent, which is manifested by the meeting of the offer and the acceptance upon the thing and the cause which are to constitute the contract.

Consent may be given only by a person with the legal capacity to give consent. In the case of juridical persons such as corporations like Mapalad, consent may only be granted through its officers who have been duly authorized by its board of directors.

In the present case, consent was purportedly given by Miguel Magsaysay, the person who signed for and in behalf of Mapalad in the deed of absolute sale dated November 2, 1989. However, as he categorically stated on the witness stand during trial, he was no longer connected with Mapalad on the said date because he already divested all his interests in said corporation as early as 1982. Even assuming, for the sake of argument, that the signatures purporting to be his were genuine, it would still be voidable for lack of authority resulting in his incapacity to give consent for and in behalf of the corporation.

On this score, the contract of sale may be annulled for lack of consent on the part of Mapalad. (G.R. No. 148516; December 27, 2007)
