Land Ownership Rules for Former Filipino Citizens in the Philippines

Below is a comprehensive discussion on the legal considerations, requirements, and procedures for changing a child’s surname in the Philippines when the child’s parents are unmarried. This overview covers the key laws and regulations, as well as the practical steps that parents may need to follow. Please note that this discussion provides general information and should not be construed as legal advice. For specific situations, it is best to consult a lawyer or relevant government agencies.


1. Governing Laws and Regulations

  1. Republic Act No. 9255 (RA 9255)

    • Commonly known as the “Revilla Law.”
    • Amends Article 176 of the Family Code of the Philippines, allowing an illegitimate child to carry the father’s surname if there is an acknowledgment of paternity.
    • Provides guidelines on when and how an illegitimate child can use the biological father’s surname, as well as conditions for changing or updating the surname in the child’s civil registry records.
  2. Family Code of the Philippines (Executive Order No. 209, as amended)

    • Articles 163–182 of the Family Code cover issues on filiation (legitimate, illegitimate, and adopted children).
    • Article 176 (as amended by RA 9255) specifically addresses the surname of illegitimate children.
  3. Administrative Orders by the Philippine Statistics Authority (PSA)

    • The PSA (formerly NSO) and the Office of the Civil Registrar General issue administrative guidelines, particularly on the steps and documents needed for changes in the civil registry.
    • Notably, Administrative Order Nos. 1 and 1, Series of 2004 and 2012, clarify the procedures to be followed in implementing RA 9255.
  4. Civil Code and Implementing Rules

    • The Civil Code contains general provisions regarding surnames and changes to the civil registry.
    • The Rules of Court (Rule 108) discuss judicial correction of entries in the civil registry under certain conditions.

2. Basic Principles on the Surname of an Illegitimate Child

  1. Default Rule

    • An illegitimate child generally carries the mother’s surname by default.
    • This principle comes from the original Article 176 of the Family Code (prior to the amendment by RA 9255).
  2. Conditions Under RA 9255

    • If the biological father acknowledges paternity—through a notarized affidavit, a Private Handwritten Instrument, or as recognized by law and jurisprudence—the illegitimate child may use the father’s surname.
    • This acknowledgment can be done at birth (when filling out the birth certificate) or even after registration of the birth certificate.
  3. Where the Father Is Unknown or Does Not Acknowledge Paternity

    • The child will remain registered under the mother’s surname.
    • There is no legal procedure to force the use of the father’s surname unless paternity is established in court.

3. Reasons for Changing a Child’s Surname

Changing a child’s surname typically arises in the following scenarios (though there may be others):

  1. Acknowledgment of Paternity After the Original Registration

    • If the child was initially registered under the mother’s surname, but the father later acknowledges paternity, the child’s surname can be changed to that of the father.
  2. Correcting the Birth Certificate

    • In cases of erroneous entries, misspellings, or typographical errors related to the father’s surname, a petition for correction may be filed.
  3. Subsequent Legitimation (in rare cases)

    • While legitimation generally applies when biological parents marry after the child’s birth, children born of void marriages (e.g., bigamous marriages) or other complexities may not qualify.
    • If legitimation is valid, the process can lead to the child carrying the father’s surname. However, for unmarried parents who do not marry, RA 9255 is typically used instead of legitimation.

4. Procedures for Changing a Child’s Surname (Unmarried Parents)

Below is an overview of the processes generally involved. Requirements may vary slightly depending on the local civil registry office’s policies.

4.1 Voluntary Acknowledgment and Use of Father’s Surname

  1. Execute an Affidavit of Acknowledgment/Paternity (AAP)

    • This affidavit must be signed by both the mother and the father if the child is a minor.
    • The father acknowledges that he is indeed the biological father; the mother consents to the change of surname.
    • The affidavit must be notarized.
  2. Submit the Required Documents to the Local Civil Registry

    • Child’s original or certified true copy of the birth certificate (registered under the mother’s surname).
    • Valid IDs of the father and mother.
    • Affidavit of Acknowledgment or Private Handwritten Instrument (if used) duly notarized or recognized by law.
    • Other supporting documents as required by the local civil registry (e.g., proof of paternity, if requested).
  3. Processing at the Local Civil Registry (LCR)

    • The LCR evaluates the documents.
    • Once approved, the LCR will annotate the birth certificate to reflect the change in the surname.
    • A new Certificate of Live Birth showing the child’s use of the father’s surname is then issued.
  4. Endorsement to the PSA

    • After approval and annotation at the LCR, the new or annotated record is endorsed to the Philippine Statistics Authority for certification.
    • This step is important to ensure that the PSA’s records match the local civil registry.

4.2 Judicial Petition (If Necessary)

In certain cases, a judicial petition might be required—particularly when:

  • The civil registry objects to the acknowledgment due to disputes regarding paternity or authenticity of documents.
  • There are complicated legal issues (e.g., the father is contesting or the mother is contesting).
  • There is an existing legal presumption that must be overcome (like in the case of a child conceived or born during a valid marriage, which triggers legitimacy presumptions).

Under Rule 108 of the Rules of Court, an interested party may file a petition for correction of the entry in the civil registry in the Regional Trial Court. If the court finds merit in the petition and orders the change of surname, the court decision will be the basis for the LCR and the PSA to annotate the birth certificate.


5. Important Considerations

  1. Consent of Both Parents

    • If the child is still a minor, the mother’s written consent is crucial unless a court order states otherwise.
    • The father’s acknowledgment is likewise essential for the child to bear his surname under RA 9255.
  2. Impact on Child’s Status

    • Using the father’s surname does not automatically make the child “legitimate.”
    • Illegitimacy remains unless there is a valid legal process of legitimation (which usually requires the parents’ subsequent valid marriage).
  3. Best Interest of the Child

    • The courts and government offices generally look at the best interest of the child in deciding on surname changes or acknowledgments.
    • In disputes, the child’s welfare prevails over parental disagreements.
  4. Proof of Paternity

    • In straightforward cases, an Affidavit of Acknowledgment is enough.
    • In contested cases, DNA testing or other forms of evidence may be required by the court.
  5. Fees and Timelines

    • Fees vary among local civil registrar offices.
    • Processing times differ by locality.
    • Once the LCR completes its annotation, endorsement to PSA can take a few weeks to months.
  6. Future Legal Implications

    • Having the father’s surname may help clarify inheritance rights and benefits under Philippine law, such as Social Security System (SSS) or PhilHealth enrollments.
    • Even if the surname is changed, illegitimate children and legitimate children have different inheritance shares unless legitimated or adopted.

6. Frequently Asked Questions

  1. Can the mother unilaterally change the child’s surname to that of the father?

    • No. The father must acknowledge paternity, usually via a notarized Affidavit of Acknowledgment or by court decision. A mother cannot make this change unilaterally.
  2. Is the father required to be physically present to sign the affidavit?

    • Typically, yes. For the affidavit to be notarized, both parents (or the father, at the very least) must appear before the notary public. Special circumstances may allow for alternative procedures, but it often requires personal appearance.
  3. What if the father refuses to acknowledge the child or sign any documents?

    • The mother may have to file a petition in court to establish paternity. Without the father’s voluntary acknowledgment or court’s determination, using the father’s surname is not possible.
  4. If the parents eventually marry, is the child automatically “legitimated”?

    • If the parents are free to marry each other (i.e., there are no legal impediments) and do so after the child’s birth, legitimation may apply. The father’s surname would then be reflected, subject to the legitimation process (a separate procedure from RA 9255).
  5. Can an adult child (18 years old and above) file the change of surname on their own?

    • Yes. Once the child reaches the age of majority, they can initiate the process of changing the surname themselves, provided they have evidence of paternity (e.g., father’s acknowledgment, DNA evidence, or a court decision). However, if the father’s cooperation is needed (such as signing an affidavit), that may still be a challenge.

7. Practical Tips

  1. Keep All Documents Organized

    • Birth certificate, IDs of both parents, and the child’s valid ID (if applicable) should be ready.
    • Affidavits of Acknowledgment should be correctly notarized to avoid rejection.
  2. Consult the Local Civil Registrar First

    • Different localities may have varying protocols or additional documentary requirements.
    • Confirm exact fees and timelines.
  3. Seek Legal Advice if Disputes Arise

    • If there is any challenge to paternity or if either parent objects, consultation with a lawyer may be necessary.
    • A judicial process could be the only remedy.
  4. Check the PSA Records Afterward

    • Even after securing the LCR annotation, make sure to request an updated copy of the birth certificate from PSA.
    • This step ensures that the changes are reflected in the national database, which is used for passports and other official documents.

8. Conclusion

Changing a child’s surname in the Philippines when the parents are unmarried is governed by RA 9255, which allows an illegitimate child to bear the father’s surname if there is acknowledgment of paternity. The process is relatively straightforward if both parents agree and submit the appropriate documents to the local civil registrar. However, in cases of dispute or refusal by one party, judicial intervention may be necessary.

Because every family’s situation can vary widely—especially with issues of paternity, parental rights, and consent—it is advisable to seek guidance from legal professionals or directly from local civil registry officials. Doing so helps ensure that the procedure is carried out correctly and that the child’s best interests remain the priority.
