Changing a Child’s Surname from Mother’s Maiden Name to Married Name

Below is a comprehensive discussion of the legal framework and procedures in the Philippines concerning changing a child’s surname from the mother’s maiden name to a married name (most often, the father’s surname). This article covers the laws, regulations, and the common processes that come into play in such scenarios. While this overview aims to be as accurate and thorough as possible, always consult a qualified attorney or the Philippine Statistics Authority (PSA) for specific guidance.

1. Key Legal Framework

1.1. Family Code of the Philippines (Executive Order No. 209)

  • Legitimate children (born to parents validly married to each other) ordinarily carry the father’s surname.
  • Illegitimate children (born out of wedlock) generally carry the mother’s surname, unless the father acknowledges the child in the manner provided by law (e.g., through an Affidavit of Acknowledgment/Admission of Paternity) and the requirements under Republic Act No. 9255 are followed.

1.2. Republic Act No. 9255 (“An Act Allowing Illegitimate Children to Use the Surname of Their Father”)

  • Amended Article 176 of the Family Code, giving illegitimate children the right to use their father’s surname if the father expressly recognizes or acknowledges them.
  • Requires compliance with certain documentary and procedural steps (e.g., submission of the Affidavit of Acknowledgment/Admission of Paternity and the Affidavit to Use the Surname of the Father or AUSF).

1.3. Republic Act No. 9048 (as amended by RA 10172)

  • Governs administrative corrections of clerical or typographical errors in civil registry documents without the need for a court order.
  • Usually deals with minor corrections (typos, errors in spelling, etc.) and certain changes in first name or day/month of birth. It does not apply to substantive changes in surname unless in specific circumstances defined by law.

1.4. Legitimation by Subsequent Marriage (Article 177 of the Family Code)

  • If the parents of an illegitimate child later marry each other, the child may be legitimated, provided that at the time of the child’s conception, there was no legal impediment for the parents to wed.
  • Once legitimated, the child is considered legitimate for all purposes and may carry the father’s surname. Proof and procedure involve executing a legitimation document and updating records with the PSA.

2. Understanding the Child’s Initial Surname

2.1. Child Born During Valid Marriage

By default, the Family Code presumes that a child born to a validly married couple is legitimate and thus automatically takes the father’s surname. No change is necessary unless there was an error in the initial registration.

2.2. Child Born Before or Outside of Marriage

  • If the child is illegitimate at birth (the mother was unmarried at the time, or the parents were not validly married), the child’s birth certificate typically shows the mother’s surname.
  • In many cases, the father’s name may be left blank if the father has not acknowledged paternity at the time of registration.

3. Common Scenarios for Changing the Child’s Surname

  1. Parents Were Not Married at the Child’s Birth, but Later Married

    • The child can be “legitimated by subsequent marriage” if no legal impediment existed at conception.
    • Once legitimation is complete, the child's surname may be changed to that of the father.

  2. Parents Remain Unmarried, but Father Acknowledges the Child

    • Under RA 9255, if the father acknowledges the child, the child may use the father’s surname upon proper compliance with the Affidavit to Use the Surname of the Father (AUSF).
    • This does not necessarily make the child legitimate, but it allows the child to carry the father’s surname.

  3. There Was an Error in the Birth Certificate

    • If the mother was already married to the father at the time of birth but the child was erroneously registered under the mother’s maiden name, a correction of entry proceeding (judicial or administrative) may be required.
    • RA 9048 procedures may be pursued if the PSA or Local Civil Registrar deems the change falls under an administrative correction, but if it is a substantive change involving filiation, a court order might be needed.

4. Detailed Steps for Changing the Child’s Surname

4.1. Legitimation by Subsequent Marriage

  1. Check for the absence of legal impediments

    • For legitimation to apply, the parents must have been free to marry each other at the time of the child’s conception or birth.
    • If there was a prior marriage that was not yet annulled, or any impediment existed, legitimation is not possible.

  2. Execute an Affidavit of Legitimation

    • Once the parents are validly married, they should secure an “Affidavit of Legitimation,” indicating they have since married and that there were no legal impediments at conception.

  3. Register the Affidavit

    • The notarized affidavit is then submitted to the Local Civil Registrar (LCR) where the child’s birth was registered.
    • The LCR updates the birth record to reflect the legitimation, and the father’s surname becomes the child’s surname on record.

  4. Secure an Annotated PSA Birth Certificate

    • After processing, the PSA will issue a new (or annotated) birth certificate showing the child as legitimate and reflecting the father’s surname.

4.2. Change of Surname Under RA 9255 (Illegitimate Child Using Father’s Surname)

If the parents were not married but the father acknowledges the child:

  1. Execute an Affidavit of Acknowledgment or Admission of Paternity

    • This typically is done either at the hospital, at the Local Civil Registrar, or before a notary public.
    • It states that the man is the father of the child.

  2. Affidavit to Use the Surname of the Father (AUSF)

    • The mother, father, or the child (if of legal age) must execute the AUSF to formally request the use of the father’s surname.
    • This affidavit is filed with the Local Civil Registrar.

  3. Register the AUSF with the Local Civil Registrar

    • The LCR reviews the documents.
    • Upon approval, the records and birth certificate are annotated to reflect the father’s surname.

  4. Obtain the Annotated PSA Certificate

    • After the LCR forwards the updated record to the PSA, you can request a new or annotated birth certificate from the PSA that shows the child’s new surname.

Important Note: This process does not change the status of the child from “illegitimate” to “legitimate.” It only affects the surname.

4.3. Correction of Entry Due to Error (RA 9048 and RA 10172)

  • If the child was in fact legitimate from birth (i.e., the parents were already married) but was inadvertently registered under the mother’s maiden name, the procedure might be considered an error in the birth record.
  • Administrative vs. Judicial Correction:
    • Administrative Correction: Possible if the Local Civil Registrar considers the change to be a mere clerical or typographical error.
    • Judicial Correction: Required if the change affects filiation or legitimacy, which is substantive. You would need to file a petition in court to direct the LCR or PSA to amend the records.

5. Additional Considerations

  1. Consent and Capacity:

    • If the child is already of legal age (18 or older), the child may personally request the change of surname but must still comply with the legal requirements for acknowledgment or legitimation.

  2. Effect on Parental Authority and Support:

    • Using the father’s surname does not necessarily alter the father’s obligation to support, or the mother’s obligations, or custody arrangements. Those are governed by other provisions of law on parental authority, support, and custody.

  3. Effect on Inheritance:

    • A child who is legitimated or acknowledged may have inheritance rights consistent with the law. Legitimated children inherit as legitimate heirs. Illegitimate but acknowledged children have rights to a certain share (though less than legitimate children). Always consult a lawyer for estate and succession matters.

  4. Practicalities and Timeline:

    • Local Civil Registrar offices may have slightly different procedures or timelines.
    • Expect to fill out forms, pay processing fees, and wait for the annotated birth certificate from the PSA.

  5. Legal Counsel:

    • If the Local Civil Registrar denies an application or if the father or other parties refuse to cooperate, court action may be necessary. In such cases, consult with a lawyer to evaluate the legal strategy.

6. Frequently Asked Questions (FAQs)

Q1: My partner and I just married, and our child was born two years ago when we were not yet married. Can our child automatically use my husband’s surname now?

  • A1: If there was no legal impediment when the child was conceived, your child can be legitimated by your subsequent marriage. You must complete the “Affidavit of Legitimation” and have the local registrar annotate the birth record. Once done, the child’s surname can be changed to that of the father.

Q2: The father of my child has acknowledged paternity, but we are not married. Can my child use his surname?

  • A2: Yes. Under RA 9255, if the father has signed an Affidavit of Acknowledgment/Admission of Paternity and you file the Affidavit to Use the Surname of the Father (AUSF) with the Local Civil Registrar, the child may use the father’s surname, subject to compliance with all documentary requirements.

Q3: What if the child is already a teenager or an adult?

  • A3: Even if the child is already of legal age, the father can still acknowledge paternity. The child can then execute the required AUSF in his or her own capacity, provided all legal conditions are met.

Q4: Will changing my child’s surname affect child support or custody?

  • A4: No. Changing the surname does not automatically affect custody or support obligations. Those aspects are determined by other provisions of the Family Code.

Q5: How long does it take to get the new PSA birth certificate?

  • A5: It can vary. After the Local Civil Registrar processes your documents, they forward them to the PSA for annotation. It may take a few weeks to several months before the updated record is available in the PSA database. Always follow up with your LCR and the PSA.

7. Conclusion

Changing a child’s surname from the mother’s maiden name to the father’s surname (or the married name) in the Philippines hinges on understanding the child’s legitimacy status, the acknowledgment of paternity, and the proper administrative or judicial procedure. Key laws—such as the Family Code, RA 9255, RA 9048, and the rules on legitimation by subsequent marriage—provide the framework for these changes.

  1. Legitimate from Birth: Children automatically follow the father’s surname if the parents were validly married at the time of birth.
  2. Illegitimate, Parents Later Marry: Legitimation by subsequent marriage can change the child’s status and surname.
  3. Illegitimate, Parents Not Married: Under RA 9255, an acknowledged child can use the father’s surname, although the child remains illegitimate.
  4. Errors in Birth Registration: Certain corrections can be done administratively if they are minor, but issues involving filiation or legitimacy generally require a judicial proceeding.

Always consult the Local Civil Registrar or an attorney for a clear, step-by-step approach for your specific case. Each family’s situation is unique, and professional legal advice ensures that you comply with all requirements and protect the child’s rights in accordance with Philippine law.
