CASE DIGEST : Concepcion A. Vizcarra, et al. v. Lilia Vizcarra-Nocillado, et al. G.R. No. 205241, January 11, 2023 GAERLAN

 The case involved the settlement of the estate of Ireneo Vizcarra, whose heirs executed an Extrajudicial Settlement of Estate and transferred ownership of his property solely among themselves. Thereafter, new Transfer Certificates of Title (TCTs) were issued in their names. The respondents, claiming to be the children of Silvestre Vizcarra, filed a complaint to declare the extrajudicial settlement and the resulting titles null and void. They alleged that Silvestre was an illegitimate son of Ireneo and, having predeceased his father, they succeeded to his hereditary rights by right of representation under the Civil Code. To establish Silvestre's filiation, they relied mainly on an NSO-issued Certificate of Live Birth, a Certification from the Local Civil Registrar, and Silvestre's marriage contract, all indicating that Ireneo was his father.

The Regional Trial Court (RTC) and the Court of Appeals (CA) ruled in favor of the respondents, holding that the NSO Certificate, being a public document, enjoyed the presumption of regularity and sufficiently proved Silvestre's filiation. Consequently, the courts declared the extrajudicial settlement void and ordered the reconveyance of the property to Ireneo's estate. The petitioners elevated the case to the Supreme Court, arguing that the NSO Certificate was merely reconstructed from a later certification rather than the original birth records and, more importantly, that the documents presented did not constitute competent proof of illegitimate filiation under the Family Code and the Civil Code.

ISSUE

Whether the respondents sufficiently established Silvestre Vizcarra's filiation to Ireneo Vizcarra through the documents they presented, thereby entitling them to inherit by right of representation and to seek the annulment of the extrajudicial settlement of Ireneo's estate.

Whether the NSO Certificate of Live Birth, Local Civil Registrar Certification, and marriage contract constituted competent evidence of paternity under Article 172 of the Family Code, in relation to Article 175, governing the proof of legitimate and illegitimate filiation.

HELD

The Supreme Court granted the petition, reversed the Court of Appeals and the RTC, and dismissed the complaint. The Court held that while public documents generally enjoy a presumption of regularity, the existence of a birth certificate stating the name of the alleged father does not by itself establish filiation. Under Articles 172 and 175 of the Family Code, illegitimate filiation must be proved by the record of birth signed by the father, an admission in a public or private handwritten instrument signed by him, or, in their absence, by open and continuous possession of the status of a child or other competent evidence allowed by the Rules of Court. The respondents failed to prove that Ireneo himself participated in or signed Silvestre's birth record or otherwise acknowledged him as his child.

The Court further ruled that because Silvestre's filiation was not legally established, the respondents had no hereditary rights to represent him in the estate of Ireneo. Consequently, they lacked legal basis to challenge the Extrajudicial Settlement of Estate or demand the reconveyance of the property. The Supreme Court emphasized that filiation cannot rest on presumptions or unverified public records alone, but must strictly comply with the modes of proof prescribed by the Family Code, since inheritance rights arise only upon valid proof of parentage. Accordingly, the complaint for the nullification of the extrajudicial settlement and cancellation of titles was dismissed.
