Children's Surnames: Illegitimate Child's Right to Choose After Father's Recognition

The Supreme Court has settled an important question for families in the Philippines: when a father recognizes his illegitimate child, can he compel the child to use his surname? In Grande v. Antonio (G.R. No. 206248, February 18, 2014), the Court answered with a clear no. The right to choose belongs to the child, not to either parent.

The Case

Grace Grande and Patricio Antonio lived together as husband and wife, although Antonio was already married to someone else. Two sons were born from this relationship. When the relationship ended, Grande moved to the United States with the children. Antonio then filed a petition in court to formally recognize his paternity and to have the children's surnames changed from "Grande" to "Antonio."

The trial court granted Antonio's petition, ordering the change of surname and awarding him custody. The Court of Appeals modified this ruling, giving sole custody to the mother but maintaining the order that the children use their father's surname. Grande appealed to the Supreme Court, arguing that Article 176 of the Family Code, as amended by Republic Act No. 9255, does not allow a father to compel his illegitimate children to use his surname.

The Law on Illegitimate Children's Surnames

Article 176 of the Family Code originally provided that illegitimate children shall use the surname of their mother. In 2004, Republic Act No. 9255 amended this provision to allow illegitimate children to use their father's surname if their filiation has been expressly recognized by the father through the record of birth in the civil register or through an admission in a public document or private handwritten instrument.

The key word in the amended provision is "may." The Supreme Court emphasized that this word is permissive, not mandatory. It operates to confer discretion upon the illegitimate child. The law does not give the father or the mother the right to dictate the surname of their illegitimate children. Only the child can decide.

The Implementing Rules Cannot Override the Law

The Court also addressed the Implementing Rules and Regulations (IRR) of RA 9255, which used the word "shall" and appeared to make the use of the father's surname mandatory upon recognition. The Court struck down these provisions as null and void.

The reason is a basic principle of law: an administrative issuance cannot amend a legislative act. The power of administrative officials to promulgate rules is limited to what is found in the legislative enactment itself. When a discrepancy occurs between the basic law and an implementing rule, the law prevails. The IRR cannot expand the coverage of the statute.

Best Interest of the Child

The Court reiterated that the yardstick for policies affecting children is their best interest. The Court has previously allowed even legitimate children to use a surname different from their father's when it serves their best interest. The rule regarding a child's surname is second only to the rule requiring that the child be placed in the best possible situation considering his or her circumstances.

In this case, the children, then aged thirteen and fifteen, had submitted letters to the Court opposing the change of their surname to "Antonio." While the Court noted these letters could not be given evidentiary weight because they were not formally offered before the trial court, the case was remanded to determine the surname the children themselves would choose.

Practical Takeaways

• An acknowledged illegitimate child has the right to choose whether to use the father's surname. Neither parent can compel the choice.
• The word "may" in Article 176 of the Family Code, as amended by RA 9255, is permissive and grants discretion to the child.
• The father's recognition of paternity does not automatically change the child's surname. The child must decide.
• Implementing rules and regulations cannot override a clear statutory provision. The IRR of RA 9255 that made the father's surname mandatory was declared void.
• Parental authority and custody over illegitimate children remain with the mother, unless she is shown to be unfit. Recognition by the father does not alter this.
