In Aguilar v. Siasat, the Supreme Court clarified how filiation, or parentage, can be legally established, particularly when official records are missing. The Court ruled that a public document, specifically an SSS E-1 form signed by the father, acknowledging the petitioner as his son, is sufficient proof of filiation under Article 172 of the Family Code. This acknowledgment in a public instrument is considered a consummated act, requiring no further court action. This decision underscores the importance of documentary evidence in inheritance disputes and the legal weight given to public documents in proving filiation, providing clarity for individuals seeking to establish their parentage rights.

From Missing Birth Records to Inheritance Rights: Can an SSS Form Prove Fatherhood?

The case of Rodolfo S. Aguilar v. Edna G. Siasat (G.R. No. 200169, January 28, 2015) arose from a dispute over the estate of the deceased spouses Alfredo Aguilar and Candelaria Siasat-Aguilar. Rodolfo Aguilar, claiming to be their son and sole heir, filed a case against Edna Siasat, the respondent, seeking to compel her to surrender the owner’s duplicate copies of the land titles belonging to the estate. Edna Siasat contested Rodolfo’s claim, asserting that he was not the couple’s son and that she held the titles for safekeeping as instructed by Candelaria Siasat-Aguilar, her aunt. The central legal question was whether Rodolfo Aguilar could sufficiently prove his filiation to the Aguilar spouses, particularly in the absence of a birth certificate, and whether an SSS form acknowledging him as a son constituted sufficient proof under the Family Code.

The Regional Trial Court (RTC) initially dismissed Rodolfo’s complaint, finding that he had not presented solid evidence of his biological or legal relationship to the deceased spouses. The RTC emphasized the absence of a birth certificate and relied on an affidavit by Candelaria Siasat-Aguilar stating that she and Alfredo had no children. However, the Court of Appeals (CA) affirmed the RTC’s decision, giving little weight to the documentary evidence presented by Rodolfo, including his school records, income tax returns, and marriage certificate. The CA particularly questioned the admissibility and probative value of Alfredo Aguilar’s SSS Form E-1, which identified Rodolfo as his son, arguing that it did not constitute clear and convincing evidence of filiation based on open and continuous possession of the status of a legitimate child.

Before the Supreme Court, the petitioner, Rodolfo Aguilar, argued that the CA erred in disregarding the SSS Form E-1 as sufficient proof of filiation under Article 172 of the Family Code. Article 172 of the Family Code provides the means of establishing the filiation of legitimate children, stating:

(1) The record of birth appearing in the civil register or a final judgment; or
(2) An admission of legitimate filiation in a public document or a private handwritten instrument and signed by the parent concerned.

Rodolfo contended that the SSS Form E-1, being a public document executed by his father, Alfredo Aguilar, acknowledging him as his son, met the requirements of Article 172. He argued that this acknowledgment should be given more weight than the presumption of legitimacy, and that the respondent had no legal standing to challenge his legitimacy collaterally. In contrast, the respondent, Edna Siasat, reiterated the CA’s position, asserting that the petitioner’s evidence failed to meet the high standard of proof required to establish legitimate filiation.

The Supreme Court disagreed with the lower courts, emphasizing the significance of the SSS Form E-1 as a public document containing an admission of filiation. The Court cited the case of De Jesus v. Estate of Dizon, which clarified that “the due recognition of an illegitimate child in a record of birth, a will, a statement before a court of record, or in any authentic writing is, in itself, a consummated act of acknowledgment of the child, and no further court action is required.” This means that once a parent acknowledges a child in an authentic writing, the filiation is established, and no further legal proceedings are necessary to confirm it. The Court found that Rodolfo, having been born during the marriage of Alfredo and Candelaria Aguilar, had sufficiently proven his legitimate filiation through the SSS Form E-1.

Building on this principle, the Supreme Court differentiated between the two paragraphs of Article 172 of the Family Code. While the second paragraph refers to situations where filiation is proven through open and continuous possession of the status of a legitimate child, the first paragraph pertains to direct admissions of filiation in public or private documents. The Court found that the CA erred in treating the SSS Form E-1 as mere evidence of open and continuous possession, when it was, in fact, a direct acknowledgment of filiation in a public instrument. The Supreme Court thus concluded that the SSS Form E-1 constituted sufficient proof of filiation under Article 172 of the Family Code.

The Court also noted that Rodolfo was unable to present his birth certificate because the local civil registry’s records for the relevant period had been destroyed. This further supported the admissibility of alternative documentary evidence, such as the SSS Form E-1. This fact pattern underscores the importance of preserving vital records and the recourse available when primary documentation is unavailable. Even without a birth certificate, the Court found that the totality of evidence, especially the SSS form, established Rodolfo’s filiation.

Consequently, the Supreme Court reversed the decisions of the Court of Appeals and the Regional Trial Court. The Court ordered Edna Siasat to surrender the owner’s duplicate copies of the land titles to Rodolfo Aguilar. This decision not only resolved the specific dispute over the Aguilar estate but also reinforced the legal principle that an admission of filiation in a public document is a conclusive act of acknowledgment, sufficient to establish parentage rights. This has significant implications for inheritance disputes and other legal matters where proof of filiation is required.

This case serves as an important reminder of the evidentiary value of public documents in establishing filiation. While a birth certificate is the primary evidence, alternative forms of documentation, such as SSS forms, can be sufficient when properly executed and presented. The Supreme Court’s decision provides clarity and guidance on how to prove filiation, particularly in situations where official records are missing or incomplete. This ultimately ensures that individuals can assert their legal rights based on credible and reliable evidence of parentage.
