G.R. Nos. L-45492 & L-45493 May 29, 1987
ERNESTO ASUNCION, petitioner, vs. HON. COURT OF APPEALS, ARSENIO MUNEZ, ANASTACIA DE CLARO VDA. DE MUNEZ, CONCHITA, VIVIAN, NILDA DELIA, RUFINO, JR., REYNALDO, ANGELITO, all surnamed MUNEZ; RODOLFO MUNEZ, ANTONIO MUNEZ, MARIA JOSEFA MUNEZ, CRISANTA MUNEZ, TAMBIS and ELISEO TINDOGAN, respondents.

FACTS

The case involves Farmlot No. 2113 in Polomolok, Cotabato. In 1941, the National Land Settlement Administration (NLSA) allocated the lot to Gorgonio Munez. He later abandoned it, and in 1949, the NLSA reallocated it to his uncle, Eugenio Munez. In 1957, both Gorgonio (as the original awardee) and Eugenio (as the subsequent allocatee) executed a notarized Affidavit of Transfer of Rights, selling their rights over the land to petitioner Ernesto Asuncion for P600.00, with Asuncion assuming all subsisting obligations with the government. Relying on this document, Asuncion filed a free patent application in 1958, cultivated the land, paid taxes, made improvements, and settled the outstanding account with the Board of Liquidators. A patent and Original Certificate of Title were subsequently issued in his name in 1965.
In 1965, Eugenio Munez (and later his heirs, the private respondents) filed two complaints: one for annulment of the transfer and recovery of possession, and another for reconveyance and nullity of title. They alleged that the 1957 document was procured through fraud and misrepresentation, claiming Eugenio only intended to lease the land, not sell it. The trial court dismissed both complaints, upholding the validity of the sale. The Court of Appeals reversed this decision, declaring the transfer, patent, and title null and void and ordering reconveyance to the respondents.

ISSUE

The core issue is whether the Affidavit of Transfer of Rights executed by Gorgonio and Eugenio Munez in favor of Ernesto Asuncion is valid, and consequently, whether the free patent and title issued to Asuncion should be annulled.

RULING

The Supreme Court reversed the Court of Appeals and reinstated the trial court’s decision, upholding the validity of the transfer and Asuncion’s title. The legal logic rests on the conclusive presumption of regularity accorded to notarized documents and the failure of the respondents to present clear and convincing evidence of fraud. The Court emphasized that a notarized document carries the weight of a public instrument and is evidence of the facts stated therein. The burden of proof to overturn such a document lies with the party challenging it, requiring proof that is clear, convincing, and more than merely preponderant. The respondents failed to meet this burden. Their claim that Eugenio was illiterate and only intended a lease was insufficient, especially since he had previously acknowledged the transfer in official communications and never acted to contest it for eight years. The Court found the respondents’ attempt to invalidate the clear terms of the affidavit to be “opportunistic.” Furthermore, Asuncion had complied with all legal requirements for a free patent applicant, having purchased the rights, assumed the obligations, cultivated the land, and paid taxes. Therefore, the patent and title issued to him were valid. The ruling protects the stability of land titles issued under public land laws and the sanctity of notarized agreements against belated and unsubstant
