Sayson vs. Court of Appeals

A final and executory decree of adoption cannot be collaterally attacked in a separate action for partition; its validity must be challenged in a direct proceeding. Furthermore, an adopted child is deemed a legitimate child of the adopters but does not acquire the right of representation to inherit from the collateral relatives of the adopters.

Eleno and Rafaela Sayson had five children, including Teodoro. Teodoro married Isabel Bautista and they had one legitimate daughter, Doribel, and adopted two children, Delia and Edmundo. After the deaths of Teodoro, Isabel, Eleno, and Rafaela, disputes arose over the inheritance of their estates. The petitioners, who are Teodoro's siblings and Isabel's mother, filed actions for partition and accounting, challenging the status of Delia, Edmundo, and Doribel as heirs.

• Nature of the Dispute: The cases involved conflicting claims to the intestate estates of the spouses Teodoro and Isabel Sayson, and of Teodoro's parents, Eleno and Rafaela Sayson.
• Status of Private Respondents: Delia and Edmundo Sayson were legally adopted by Teodoro and Isabel pursuant to a final decree of adoption dated March 9, 1967. Doribel Sayson was their legitimate daughter, as evidenced by a birth certificate dated February 27, 1967.
• Petitioners' Challenge: The petitioners sought to annul the adoption of Delia and Edmundo, arguing that Teodoro and Isabel were disqualified from adopting under Article 335 of the Civil Code because they already had a legitimate child (Doribel) at the time the adoption decree was issued. They also contested Doribel's legitimacy, alleging she was born to another woman.
• Lower Court Findings: The trial courts found the adoption decree and birth certificate to be valid and binding, establishing the private respondents as lawful heirs.
• Appellate Court Ruling: The Court of Appeals affirmed the validity of the adoption and legitimacy but modified the ruling on the estate of Eleno and Rafaela, holding that only Doribel could inherit by right of representation.

• Invalid Adoption: Petitioners argued that the adoption of Delia and Edmundo was void ab initio because Teodoro and Isabel already had a legitimate child (Doribel) at the time the decree was issued, disqualifying them under Article 335(1) of the Civil Code.
• Illegitimacy of Doribel: Petitioners maintained that Doribel was not the legitimate daughter of Teodoro and Isabel but was born to one Edita Abila, thus undermining the basis for disqualifying the adoption and her own right to inherit.
• Right to Inherit from Grandparents: Implicitly, petitioners argued that the private respondents, even if heirs of Teodoro and Isabel, should not exclude them from the estate of Eleno and Rafaela.

• Finality of Adoption Decree: Respondents countered that the adoption decree had long become final and executory and could not be attacked collaterally in a partition proceeding.
• Evidentiary Weight of Birth Certificate: Respondents argued that Doribel's birth certificate constituted prima facie evidence of her filiation and legitimacy, which the petitioners failed to refute with competent evidence.
• Exclusive Heirship: Respondents asserted that as the legally recognized children of Teodoro and Isabel, they were the exclusive heirs to their parents' intestate estate.

• Validity of Adoption: Whether the adoption of Delia and Edmundo Sayson could be collaterally attacked and declared void in an action for partition.
• Legitimacy of Doribel Sayson: Whether the petitioners successfully rebutted the prima facie evidence of Doribel's legitimacy provided by her birth certificate.
• Right of Representation: Whether the adopted children (Delia and Edmundo) have the right of representation to inherit from their adoptive grandparents (Eleno and Rafaela Sayson).

• Validity of Adoption: The collateral attack on the adoption decree was improper. A final and executory decree of adoption can only be challenged in a direct proceeding instituted for that specific purpose. The trial court's jurisdictional finding that the adopters were qualified stands until reversed on appeal.
• Legitimacy of Doribel Sayson: The birth certificate is a public document and constitutes prima facie evidence of the facts therein. The petitioners' evidence, consisting mainly of an interested party's testimony and an un-offered affidavit, was insufficient to overcome this presumption.
• Right of Representation: While an adopted child is deemed a legitimate child for all purposes, the relationship created is solely between the adopted child and the adoptive parents. It does not extend to the adoptive parents' relatives. Therefore, only Doribel, as the legitimate granddaughter, could inherit from Eleno and Rafaela by right of representation under Article 981 of the Civil Code.

• Prohibition Against Collateral Attack of Adoption Decrees — An adoption decree that has become final and executory cannot be assailed in a separate, incidental action (like a partition suit). Its validity must be contested in a direct action filed for that purpose. This doctrine protects the stability and integrity of the adoptive relationship.
• Right of Representation in Intestate Succession — The right of representation is a legal fiction that allows a descendant to step into the place of a predeceased ascendant and inherit the share the latter would have received. This right is confined to blood relatives. An adopted child, while inheriting from the adoptive parents as a legitimate child, does not acquire the right to represent the adoptive parent in the inheritance from the adoptive parent's ascendants or collaterals.

• "The settled rule is that a finding that the requisite jurisdictional facts exists, whether erroneous or not, cannot be questioned in a collateral proceeding, for a presumption arises in such cases where the validity of the judgment is thus attacked that the necessary jurisdictional facts were proven."
• "The legitimacy of the child can be impugned only in a direct action brought for that purpose, by the proper parties, and within the period limited by law. The legitimacy of the child cannot be contested by way of defense or as a collateral issue in another action for a different purpose."
• "While it is true that the adopted child shall be deemed to be a legitimate child and have the same right as the latter, these rights do not include the right of representation. The relationship created by the adoption is between only the adopting parents and the adopted child and does not extend to the blood relatives of either party."

• Santos v. Aranzanso, 16 SCRA 344 — Cited for the rule that an adoption order implies a finding of necessary facts and cannot be considered void in a collateral attack; its determination must stand until reversed on appeal.
• Legaspi v. Court of Appeals, 142 SCRA 82 — Cited for the principle that the evidentiary nature of public documents (like a birth certificate) must be sustained absent strong, complete, and conclusive proof of its falsity.
• Teotico v. Del Val, 13 SCRA 406 — Cited to support the holding that the relationship created by adoption is limited to the adopting parents and the adopted child, not extending to the former's blood relatives.

• Article 335(1), Civil Code — Enumerates persons who cannot adopt, including those who have legitimate children. Invoked by petitioners to argue the adoption was void.
• Article 265, Civil Code & Article 172, Family Code — Provide that a birth certificate is a recognized means of establishing filiation.
• Articles 970, 971, 979, & 981, Civil Code — Define the right of representation and establish the order of intestate succession, including the status of adopted children.
