Thus, all the elements of a valid contract of sale under Article 1458 of the Civil Code, are present, such as: (1) consent or meeting of the minds; (2) determinate subject matter; and (3) price certain in money or its equivalent. In addition, Article 1477 of the same Code provides that "the ownership of the thing sold shall be transferred to the vendee upon actual or constructive delivery thereof." The plaintiff-appellee Julio Tapec himself, testified during cross-examination that Ireneo Raguirag (father of defendants-appellants) was already in possession of the parcel of land when the subject land was offered to him by the vendor, Rosario Gonzales. (Original Records, TSN, June 26, 1986, p. 8) Moreover, Constancia Gonzales, a sister of the vendor of the plaintiffs-appellees, and a witness for the defendants-appellants, testified that the subject pastureland was sold to the grandfather of the defendants-appellants as told to her by her parents; and that the predecessors-in-interest of the defendants-appellants have been in possession of the property since they bought it. (Original Records, TSN, November 23, 1988, pp. 2-3).

The validity of the sale of the subject pastureland to the predecessors-in-interest of the defendants-appellants cannot be disputed. Contracts shall be obligatory, in whatever form they may have been entered into, provided all the essential requisites for their validity are present. (Article 1356, New Civil Code) We do not agree with the ruling of the trial judge that under Article 1358 of the New Civil Code, a contract which have for their object the creation, transmission, modification or extinguishment of real rights over immovable property, must appear in a public document to be valid and enforceable.

Article 1358 of the New Civil Code enumerates certain contracts that must appear in public or private documents. This provision does not require such form in order to validate the act or contract but to insure its efficacy. Contracts enumerated by this article are, therefore, valid as between the contracting parties, even when they have not been reduced to public or private writings. (Tolentino, Arturo M., Commentaries and Jurisprudence on the Civil Code of the Philippines, Volume Four, 1985 ed., pp. 549-550) Therefore, the Deed of Sale in favor of the predecessor-in-interest of the defendants-appellants is considered valid and enforceable, even if it was only embodied in a private writing.

In upholding the validity of the 1931 sale of the subject pastureland, we can only conclude that when the land was sold to the plaintiffs-appellees in 1950, the vendor had no right to sell the subject property since at that time her family no longer owned the land and thus no legal right was transferred by the vendor to the plaintiffs-appellees. Article 1459 of the New Civil Code requires that the vendor must have a right to transfer the ownership thereof at the time it is delivered, otherwise the contract of sale is void.

Article 1544 of the New Civil Code on double sales does not apply in this case. The article provides that if an immovable property should have been sold to different vendees, the ownership shall belong to the person acquiring it who in good faith first recorded it in the Registry Property. In order that the abovementioned provision may be invoked, it is necessary that the conveyance must have been made by a party who has an existing right in the thing, and the power to dispose of it. It cannot, therefore, be invoked in a case where the two different contracts of sale are made by two different persons, one of them not being the owner of the property sold. (Tolentino, Arturo M., Commentaries and Jurisprudence on the Civil Code of the Philippines, Volume Five, 1959, pp. 83-84). ²¹
