I. Introduction

In the Philippines, names—and the legal processes surrounding them—are governed primarily by statutes such as the Family Code of the Philippines, Republic Act No. 9255 (Revilla Law), Republic Act No. 8552 (Domestic Adoption Act), and relevant jurisprudence. One issue that frequently arises is whether and how a child’s surname may be changed after the child’s mother marries (or remarries).

This article lays out the key considerations, possible scenarios, and legal procedures involved in changing a child’s surname after the mother marries in the Philippine context.

II. Basic Principles on a Child’s Surname

1. Legitimate Children

   • Under the Family Code, a legitimate child generally carries the father’s surname.
   • If the parents were validly married at the time of the child’s birth, that child is considered legitimate, and thus the standard rule is to use the father’s last name.

2. Illegitimate Children

   • In general, an illegitimate child (born outside of a valid marriage) uses the mother’s surname.
   • However, Republic Act No. 9255 (the “Revilla Law”) allows an illegitimate child to use the father’s surname if the father expressly recognizes or acknowledges the child. This is commonly done through an Affidavit of Acknowledgment/Affidavit of Admission of Paternity.

3. Effect of Subsequent Marriage of the Child’s Parents

   • Under Article 177 of the Family Code, if the biological parents of an illegitimate child subsequently marry and there were no legal impediments to marry each other at the time of the child’s birth, the child is deemed “legitimated” by that marriage. This means that the child’s status changes to legitimate, and the child may use the father’s surname with proper annotation on the birth certificate.

4. Changing Surnames in General

   • In the Philippines, a change of name (including surname) in official civil registry documents typically requires either (a) a judicial proceeding (court process) or (b) an administrative proceeding under the Office of the Civil Registrar, depending on the nature of the change, the grounds, and the applicable law.
   • Commonly, a mere personal desire to “adopt the new surname” of the mother’s spouse is insufficient. The legal processes—such as legitimation (if biological parents marry each other), adoption, or correction of entry—are the usual routes to effect a surname change.

III. Scenarios for Changing a Child’s Surname After the Mother Marries

Scenario A: Mother Marries the Biological Father of the Child

1. Legitimation

   • If the child was born when the parents had no legal impediment to marry each other (i.e., both were single at the time of birth, or any prior marriages had been annulled), then by virtue of Article 177 of the Family Code, the subsequent marriage of the parents “legitimates” the child.
   • The legitimation process will allow the child to use the father’s surname.

2. Procedure

   • The parents should file documents with the local civil registry (or through the Philippine Statistics Authority [PSA], depending on local practice) including:
     • A Legitimation Form (usually the affidavit of legitimation or similar document).
     • The child’s original birth certificate.
     • Marriage certificate of the parents.
     • Proof that no legal impediment existed at the time of the child’s birth.
   • Once approved, the birth certificate will be annotated, reflecting the child’s new status as legitimate and change of surname (if the child was originally registered under the mother’s surname).

Scenario B: Mother Marries a Man Who Is NOT the Biological Father

1. General Rule: No Automatic Change

   • There is no automatic right for a child to adopt the new (stepfather’s) surname solely because the mother has married someone else.
   • The child’s surname is determined by the principles stated above (legitimacy, illegitimacy, recognition by the father).

2. Adoption by Stepfather

   • If the stepfather wants the child to carry his surname, the typical legal pathway is adoption under Republic Act No. 8552 (Domestic Adoption Act).
   • Through adoption, the adopting parent effectively becomes the child’s legal father, and the child is legally entitled to use the adoptive father’s surname.

3. Adoption Procedure

   • Petition in Court: The prospective adoptive parent (stepfather) must file a petition for adoption before the Regional Trial Court (Family Court) in the child’s place of residence.
   • Consent and Notification: If the child is over the age of ten (10), the child’s consent is required. Likewise, if the biological father is known and has recognized the child, his written consent or notice may be required.
   • Supervised Trial Custody: The law typically requires a trial custody period (except in certain cases such as step-parent adoption where the child has already been living with the prospective adoptive parent).
   • Decree of Adoption: Once the court grants the Petition for Adoption, a Decree of Adoption is issued.
   • Amended Birth Certificate: The adoption is then recorded in the civil registry, and the child’s birth certificate is annotated to reflect the new surname and the name(s) of the adoptive parent(s).

4. Father’s Consent or Waiver

   • If the child has a recognized biological father (i.e., the father’s name appears on the birth certificate or there was an acknowledgment under RA 9255), the court may require his consent or, at minimum, proof that the father has been notified.
   • In cases where the father cannot be located or refuses to give consent, the court will examine the circumstances to determine if adoption still serves the best interest of the child.

IV. Other Legal Considerations

1. Court Petitions for Change of Name

   • If the mother is merely seeking to change the child’s surname (for example, from the father’s surname back to the mother’s surname, or from the mother’s surname to a new surname) without adoption or legitimation, a petition for change of name under Rule 108 (Rules of Court) or under Republic Act No. 9048 (as amended by RA 10172) may be filed.
   • However, these petitions usually require strong justifications—such as the child’s best interests, confusion arising from the use of different surnames, or that the father’s surname was used without the father’s recognition—and are subject to judicial or administrative scrutiny.

2. Illegitimate Children and the Revilla Law (RA 9255)

   • An illegitimate child may use the father’s surname if there is a formal acknowledgment or recognition by the father. If the father did not recognize the child, it is difficult to effect the use of that father’s surname. Conversely, if the child is already using the father’s surname by virtue of RA 9255 and the mother wishes to revert to her maiden name or to change the child’s surname to the stepfather’s name, the process likely involves either:
     • Judicial petition for change of name (demonstrating compelling reasons); or
     • Adoption by the stepfather.

3. Passport, School Records, and Other Documents

   • Name changes must be reflected consistently across official documents. Once the local civil registrar and PSA annotate the birth certificate, you can proceed to update the child’s passport, school records, and other IDs.
   • Always provide official copies of the annotated birth certificate or the court decree (adoption or change of name) when updating documents.

4. Best Interest of the Child

   • In all legal matters involving minors, the paramount consideration is the child’s best interest. Judges and government officials often scrutinize how a surname change could impact the child emotionally, psychologically, and socially.

V. Step-by-Step Summary

1. Identify the Child’s Status

   • Are they legitimate or illegitimate? Is the father’s name on the birth certificate? Has the father acknowledged paternity?

2. Determine the Proper Legal Route

   • Legitimation (if the mother marries the child’s biological father and no impediments existed at the time of birth).
   • Adoption (if the mother marries someone other than the child’s biological father and they wish for the stepfather’s surname to be used).
   • Judicial or Administrative Petition for Change of Name (in certain cases where the mother wants to revert or change the child’s surname without an adoption or legitimation process—but these are more complex and require strong justification).

3. Coordinate with the Local Civil Registry

   • For legitimation or minor changes/corrections (like typographical errors), the local civil registry or PSA can provide guidance on administrative procedures.

4. Seek Legal Counsel

   • Each case is unique—especially if the biological father is recognized, cannot be located, or refuses to give consent. Consult a lawyer who specializes in family law to determine the best strategy and to handle petitions or court proceedings.

5. Secure the Amended/Annotated Documents

   • After successful legitimation, adoption, or a granted court petition for a change of name, ensure you obtain certified true copies of the amended birth certificate and/or the court decree. These documents are essential for updating the child’s records (school, passport, etc.).

VI. Conclusion

Changing a child’s surname in the Philippines after the mother marries (or remarries) hinges on the child’s legal status (legitimate or illegitimate), the identity and acknowledgment of the biological father, and whether a stepfather is willing to adopt. The law emphasizes the child’s best interests and adheres to established procedures—such as legitimation for children whose biological parents eventually marry, or adoption when the mother’s spouse is not the child’s biological father.

Because the process can be technical and emotionally charged, seeking professional legal advice is prudent. A competent family lawyer can guide mothers and prospective adoptive fathers through the relevant statutes, court procedures, and required documentation, ensuring that any change of surname fully complies with Philippine law and protects the child’s welfare.
