G.R. No. L-46439. April 24, 1984.
ANDREA M. MOSCOSO, petitioner, vs. COURT OF APPEALS and MAXIMINA L. MORON, respondents.

FACTS

Petitioner Andrea M. Moscoso applied for land registration of a residential lot in Palo, Leyte, claiming ownership by inheritance from her father, Pascual Monge. She asserted that she and her predecessors-in-interest had been in continuous, public, and adverse possession since time immemorial. Private respondent Maximina L. Moron, along with others, opposed the application. They claimed to be the acknowledged natural children of Pascual Monge with Zenona Lanuncia, born before his marriage to Guadalupe Oliver, Moscoso’s mother. The oppositors asserted that the land’s original owner, Isidra Vigera Monge (Pascual’s mother), had verbally donated the lot to them for their home before her death in 1915. Alternatively, they claimed ownership by acquisitive prescription.
The trial court found that the oppositors, particularly Maximina Moron, had successfully proven they were Pascual Monge’s acknowledged natural children. It rejected the claim of verbal donation for lack of proof but held that the land formed part of Pascual Monge’s estate. Consequently, it ordered the land registered in co-ownership, allocating shares to Moscoso and the oppositors. The Court of Appeals affirmed this decision, leading Moscoso to elevate the case to the Supreme Court via certiorari.

ISSUE

The primary issue is whether the Court of Appeals erred in affirming the trial court’s decision to register the land in co-ownership, recognizing private respondent Maximina L. Moron as a co-owner entitled to a share of the estate of their common father, Pascual Monge.

RULING

The Supreme Court modified the appealed decision but affirmed the core ruling that Maximina L. Moron is an acknowledged natural child entitled to a share. The Court upheld the factual findings of the lower courts, which are generally conclusive. It found that Moron’s status as an acknowledged natural child was sufficiently proven by a public document—a power of attorney executed by Pascual Monge in her favor in 1945, which constituted an act of acknowledgment under the old Civil Code.
The legal logic centers on the rules of succession governing the estate of Pascual Monge, who died in 1950 before the effectivity of the New Civil Code; thus, the Spanish Civil Code applies. Under Article 840 of the Spanish Civil Code, an acknowledged natural child is entitled to a hereditary portion equal to one-half of the share of each legitimate child, provided no mejora (betterment) was made. The trial court and the Court of Appeals erred in their computation of shares. Pascual Monge was survived by six legitimate children (including Moscoso, who had acquired the shares of her five siblings) and one acknowledged natural child (Moron). Applying the law, Moron is entitled to a share equivalent to half of a legitimate child’s portion. The correct distribution is 12/13 to Moscoso (representing the consolidated shares of the six legitimate children) and 1/13 to Moron. The Supreme Court emphasized that the land, being part of Pascual Monge’s estate, must be distributed according to these mandatory legal shares of compulsory heirs.
