Changing Child's Surname to Father's Surname

Below is a comprehensive discussion of the legal framework, requirements, and procedures involved in changing a child’s surname to the father’s surname under Philippine law. Please note that this overview is intended for general informational purposes only and should not be taken as legal advice. For any specific concerns, it is best to consult a qualified attorney or seek guidance from the appropriate government agencies.


1. Relevant Laws and Governing Rules

  1. The Family Code of the Philippines (Executive Order No. 209, as amended):

    • Establishes rules on paternity, filiation (whether legitimate or illegitimate), and parental authority.
    • Sets forth how legitimate and illegitimate children acquire their surnames under general circumstances.
  2. Republic Act No. 9255 (RA 9255) – “An Act Allowing Illegitimate Children to Use the Surname of Their Father”:

    • Governs the use of the father’s surname by an illegitimate child, provided certain requirements (like acknowledgment or recognition) are met.
    • Amended Article 176 of the Family Code, clarifying procedures when changing an illegitimate child’s surname to that of the father’s.
  3. Republic Act No. 9048 (RA 9048), as amended by RA 10172 – “Clerical Error Law”:

    • Allows administrative correction of certain errors in the Civil Registry without the need for a court order.
    • Typically covers clerical or typographical errors but not substantial changes to surname unless specific requirements under RA 9255 or other rules are satisfied.
  4. Rule 108 of the Rules of Court (Judicial Proceedings for Cancellation or Correction of Entries in the Civil Registry):

    • Governs court petitions for significant changes or corrections in a birth certificate (e.g., changing the surname from mother’s to father’s if the conditions are not met for an administrative process).

2. Distinction Between Legitimate and Illegitimate Children

A. Legitimate Children

  • A child is deemed legitimate if born within a valid marriage or within 300 days after its dissolution (unless there is proof to the contrary).
  • As a general rule, legitimate children carry the father’s surname by operation of law.
  • No additional change of surname procedure is required if the child’s legitimacy is clearly established on the birth certificate and the father’s name is properly indicated at birth.

B. Illegitimate Children

  • A child is considered illegitimate if the parents were not married at the time of birth or if the marriage is void from the beginning.
  • Under Article 176 of the Family Code (as amended by RA 9255), illegitimate children shall primarily use the surname of the mother.
  • However, illegitimate children may use the father’s surname if the following conditions are met:
    1. The father has expressly recognized the child; and
    2. The father and the child’s mother execute a public document or private handwritten instrument where the father acknowledges the child.

3. Requirements for an Illegitimate Child to Use the Father’s Surname Under RA 9255

To invoke RA 9255, certain procedural and documentary requirements are necessary:

  1. Acknowledgment or Recognition by the Father

    • This can be done through:
      • An Affidavit of Admission of Paternity (AAP) or
      • An Affidavit of Acknowledgment executed jointly by both parents, or
      • Other forms of written acknowledgment recognized by law (e.g., a duly notarized private handwritten instrument explicitly recognizing the child).
    • The father must be of legal age at the time of execution.
    • If the child is of the age of majority (18 years or older), courts will generally require the child’s explicit consent to any change of surname.
  2. Consent of the Mother (for children below seven [7] years of age)

    • RA 9255 and its Implementing Rules and Regulations (IRR) require the mother’s written consent if the child is a minor below seven (7) years old.
    • If the child is 7 years old and above, the child’s opinion or preference may be weighed by the appropriate civil registry or the court, depending on the nature of the proceeding.
  3. Submission to the Local Civil Registrar (LCR)

    • The father or either parent (if authorized) must submit a certified copy of the child’s birth certificate and all supporting documents (Affidavit of Acknowledgment, etc.) to the Local Civil Registrar of the city or municipality where the birth was recorded.
    • Once approved, the civil registrar will annotate or amend the birth record to reflect the father’s surname.
  4. Fees and Other Administrative Requirements

    • Filing fees may vary depending on the locality.
    • The LCR may also require the personal appearance of one or both parents.
    • Some LCR offices request a valid government-issued ID from both parents and witnesses (if necessary).

4. Administrative Versus Judicial Process

A. Administrative Process

  • When It Is Applicable:
    • If the birth certificate has no mention of the father and the father meets all requirements for acknowledgment.
    • If there is no dispute as to the paternity (i.e., the father and mother voluntarily agree).
    • The Local Civil Registrar can annotate the birth record without a court order as long as documentary requirements under RA 9255 are completed and there is no opposition.
  • Steps:
    1. Prepare the Affidavit of Admission of Paternity or Affidavit of Acknowledgment.
    2. Obtain the mother’s written consent (for children under 7 years old).
    3. Submit the affidavit, consent, and other required documents (plus fees) to the LCR.
    4. Wait for the LCR to annotate the child’s birth certificate.
    5. Request a new copy of the birth certificate from the Philippine Statistics Authority (PSA) after the annotated version is transmitted to the PSA.

B. Judicial Process (Rule 108 of the Rules of Court)

  • When It Is Required:
    • If there is dispute regarding paternity (e.g., the father refuses to acknowledge the child, or another person contests the recognition).
    • If there is a previous entry in the birth certificate that conflicts with the claim of paternity (e.g., another man was listed as father).
    • If the Local Civil Registrar denies the petition or if the case does not fall within the scope of RA 9255 for administrative correction (for example, if you are fundamentally changing the child’s status, or there are complex questions of identity and filiation).
  • Steps:
    1. Consult a lawyer to file a Petition for Correction/Cancellation of Entry in the Civil Registry under Rule 108.
    2. The court will set the case for hearing and require the petitioner to show evidence of paternity, such as DNA tests, acknowledgment documents, testimonies, etc.
    3. If the court grants the petition, it will issue a final order directing the LCR to amend or annotate the birth certificate.
    4. Once the LCR receives the court’s order, it will effect the changes.
    5. Request an updated birth certificate from the PSA reflecting the new surname.

5. Practical Considerations

  1. Timing

    • If the child is a minor, the mother’s consent is crucial.
    • Administrative proceedings at the LCR typically take a few weeks to a few months, depending on the volume of applications.
    • Judicial processes can take much longer (several months to over a year).
  2. Child’s Welfare and Best Interest

    • Philippine courts always consider the best interest of the child when deciding matters of surname changes, especially if the child is old enough to express preference (usually 7 years old and above).
  3. Proof of Paternity

    • Clear acknowledgment by the father is mandatory under RA 9255. In contested cases, the court may order DNA testing or require additional evidence.
  4. Effect on Legitimacy Status

    • Even if an illegitimate child uses the father’s surname, the child does not automatically become “legitimate.”
    • Legitimacy status can only be changed if the child’s parents subsequently marry (and the status is legitimated under certain conditions) or by a judicial process proving validity of marriage at the time of conception/birth.
  5. Additional Documents

    • Educational, health, and other government records must eventually be updated once the surname has been formally changed.
    • In cases of foreign travel or dual citizenship, any updates to the child’s name in passports or other IDs must align with the newly annotated birth certificate.
  6. Legal Counsel

    • While administrative processes at the LCR can often be managed without a lawyer, seeking legal advice is strongly recommended for any disputed paternity or if the LCR denies the administrative petition.
    • For judicial proceedings, representation by a lawyer is almost always necessary.

6. Step-by-Step Guide (Summary)

  1. Verify Child’s Status

    • Determine if the child is legitimate or illegitimate. If legitimate, the child typically already has the father’s surname. If illegitimate, proceed under RA 9255.
  2. Secure Father’s Acknowledgment

    • For illegitimate children, prepare and notarize an Affidavit of Admission of Paternity (AAP) or Affidavit of Acknowledgment. Both parents must sign if the child is a minor below 7 years old.
  3. Check Administrative vs. Judicial Route

    • If uncontested and the father is already acknowledging the child, file an administrative petition at the Local Civil Registrar.
    • If contested or complicated (e.g., another father’s name on record, refusal to acknowledge), file a judicial petition (Rule 108) through the Regional Trial Court.
  4. Submit Requirements to the Local Civil Registrar

    • Include the child’s original or certified true copy of the birth certificate, affidavits, IDs, the mother’s written consent (if applicable), and pay the necessary fees.
  5. Follow Up with Civil Registrar & PSA

    • Once approved or upon receipt of a court order, the LCR will annotate/amend the birth record. After the LCR transmits the updated record to the PSA, request a new PSA-certified birth certificate.
  6. Update Records

    • Inform schools, health providers, passport/immigration offices, banks, and other agencies of the child’s new surname. Provide the updated birth certificate as proof.

7. Conclusion

Changing a child’s surname to the father’s surname in the Philippines involves understanding both family law provisions and civil registry regulations. RA 9255 provides a relatively straightforward administrative process when there is no paternity dispute, but contested cases or those with conflicting records typically require judicial intervention. The best interests of the child, the consent of the mother (depending on the child’s age), and clear acknowledgment from the father are all crucial components of a successful surname change.

If you are looking to change a child’s surname to that of the father, begin by gathering the required documents—particularly evidence of paternity—and consult with the Local Civil Registrar to confirm eligibility for an administrative application. In more complex cases, seek professional legal assistance to guide you through the judicial procedure under Rule 108 of the Rules of Court. Through the correct process, and upon completing the legal requirements, an illegitimate child can lawfully bear the father’s surname in the Philippines.
