G.R. No. L-25715. January 3, 1985.
HEIRS OF RAYMUNDO C. BAÑAS, plaintiffs-appellants, vs. HEIRS OF BIBIANO BARAS, defendants-appellees.

FACTS

The plaintiffs-appellants, heirs of Raymundo Bañas, filed a complaint for partition, claiming Raymundo was the acknowledged natural son of the late Bibiano Bañas, thereby entitling them to a share in Bibiano’s estate. They presented a handwritten note (“Nota”) dated May 23, 1907, purportedly from Bibiano to the then 13-year-old Raymundo, which contained affectionate language and closed with “su padre que te adora, Bibiano Bañas.” The defendants-appellees, Bibiano’s heirs, denied any filiation or acknowledgment. They countered that Raymundo was actually the natural son of Pedro Bañas, Bibiano’s brother. In support, they presented sworn statements executed by Raymundo and Pedro Bañas in 1928, wherein Raymundo declared his father was the “unknown” Pedro Bañas, not Bibiano, and sought to correct an error in his 1926 marriage certificate which had initially named Bibiano as his father.
The trial court dismissed the complaint. It found the 1907 Note insufficient to constitute voluntary acknowledgment. It gave greater weight to the 1928 sworn statements, which it deemed a clear repudiation of Bibiano’s paternity by Raymundo himself. The court also noted the suspicious nature of the Note, including its belated production and an incongruous use of formal Spanish language inconsistent with a paternal letter to a young son.

ISSUE

Whether the 1907 handwritten Note constituted a valid act of voluntary acknowledgment, making Raymundo Bañas an acknowledged natural child of Bibiano Bañas, thus entitling his heirs to a hereditary share.

RULING

The Supreme Court affirmed the dismissal, holding that the Note did not constitute a valid act of acknowledgment. The legal logic centered on the requirements for voluntary recognition under the Civil Code. For a writing to serve as an act of acknowledgment, it must be an express and unequivocal declaration of paternity made voluntarily by the putative parent. The Court found the Note ambiguous; its affectionate tone did not necessarily equate to a clear recognition of filiation. More critically, any possible inference of acknowledgment was conclusively negated by Raymundo’s own subsequent act.
In his 1928 sworn statement, Raymundo explicitly declared Pedro Bañas as his father and sought to correct the record that had mistakenly named Bibiano. This act constituted a direct repudiation of Bibiano’s paternity. The law requires that acknowledgment must be made with the express will of the parent and, for the child’s status to be fixed, it cannot be contradicted by the child’s own definitive repudiation. Raymundo’s deliberate and formal disavowal of Bibiano as his father in 1928, made when he was of full age and capacity, nullified any alleged acknowledgment from the 1907 Note. Therefore, no filiation was established, and the plaintiffs-appellants had no right to inherit from Bibiano’s estate. The Court also upheld the trial court’s assessment of the Note’s dubious authenticity, reinforcing the conclusion that the plaintiffs failed to discharge their burden of proof.
