G.R. No. 77867 February 6, 1990
ISABEL DE LA PUERTA, petitioner, vs. THE HONORABLE COURT OF APPEALS and CARMELITA DE LA PUERTA, respondents.

FACTS

Dominga Revuelta died in 1966, leaving a will that bequeathed her estate to her three children: Alfredo, Vicente, and Isabel de la Puerta. Isabel was appointed executrix. During the probate proceedings, Vicente filed a petition to adopt Carmelita de la Puerta in 1974, which was granted. Isabel appealed this adoption decree. Following Vicente’s death, Carmelita intervened in the probate proceedings, filing a motion for a monthly allowance as Vicente’s acknowledged natural child. The probate court granted her motion, finding sufficient evidence that Carmelita was Vicente’s natural child with Gloria Jordan. This decision was affirmed by the Court of Appeals.
Isabel petitioned the Supreme Court, arguing Carmelita could not be Vicente’s natural child because Vicente was married to Genoveva de la Puerta since 1938. Isabel invoked the presumption of legitimacy under the Civil Code, contending Carmelita was the legitimate child of Juanita Austrial and Gloria Jordan. She presented witnesses to support this claim, including Vicente’s estranged wife, Genoveva, who testified that Vicente and Gloria Jordan lived together openly.

ISSUE

The core issue is whether Carmelita de la Puerta is the acknowledged natural child of Vicente de la Puerta, thereby entitling her to support from his estate, and whether the factual findings of the lower courts on her filiation are binding.

RULING

The Supreme Court reversed the Court of Appeals. The Court held that Carmelita could not be Vicente’s acknowledged natural child because, under the Civil Code, a natural child is one born out of wedlock to parents who, at the time of conception, were not disqualified from marrying each other. Since Vicente was legally married to Genoveva at the time of Carmelita’s conception and birth, any child he fathered with another woman could only be considered spurious (illegitimate), not natural. The legal distinction is crucial for successional rights.
The Court further ruled that the lower courts erred in their legal characterization. While the factual findings—that Vicente treated Carmelita as his daughter, provided support, and acknowledged her in school records and court testimony—were generally accorded respect, these facts do not alter her legal status from spurious to natural. The presumption of legitimacy cited by Isabel, regarding children born to a married woman, was not the central doctrine applied; instead, the Court focused on the specific legal definition of a “natural child” and the marital impediment.
Consequently, as a spurious child, Carmelita’s inheritance rights are limited to her father’s (Vicente’s) estate and do not extend to the estate of her grandmother, Dominga Revuelta. Her claim for support should be pursued in the settlement of Vicente’s intestate estate, not in the probate of Dominga’s will. The petition was granted.
