Changing a Child’s Surname in the Philippines
(Comprehensive Legal Guide – updated to 30 May 2025)
1. Governing Framework
| Source | Key Provisions |

2. Types of Children and Default Surname Rules
- Legitimate child – automatically bears the father’s surname (Civil Code art. 364; Family Code art. 174).
- Illegitimate child – by default carries the mother’s surname (Family Code art. 176) unless R.A. 9255 procedures are followed.
- Legitimated child – once legitimated under R.A. 9858, child’s surname becomes the father’s (Family Code art. 177).
- Adopted child – takes the adopter’s surname (R.A. 11642, §24).
3. Pathways to Change a Child’s Surname
A. Administrative Routes (No Court Appearance)
| Scenario | Legal Basis | Who Files / Where | Main Requirements | Typical Timeline & Fees* |
|---|---|---|---|---|
| 1. Clerical/Typographical error in surname (e.g., “Dela Cruz” vs “De la Cruz”) | R.A. 9048/10172 | Parent/child ≥ 18 at Local Civil Registry (LCR) where birth recorded or where child resides | Petition (notarized), supporting docs, photocopies of ID, PSA-issued birth certificate, fee ₱1,000 (₱3,000 if foreign-born) | 3-6 months |
| 2. Illegitimate child wishes to use father’s surname | R.A. 9255 & PSA Memo Cir. 2021-003 | Mother (or father/mother jointly) at LCR | Affidavit to Use the Surname of the Father (AUSF) + Acknowledgment of Paternity (any one): a) Birth cert with Affidavit of Acknowledgment, b) AFFP, c) Private handwritten instrument, d) DNA result accepted by father. | 2-4 months; reg. fee ₱1,000 |
| 3. Legitimation by subsequent marriage | R.A. 9858 | Parents (or child ≥ 18) at LCR | PSA birth cert, PSA marriage cert, sworn petition for legitimation, copy to OSG | 1-3 months; reg. fee ₱1,000 |
| 4. Rectification of simulated birth | R.A. 11222 | Petition before National Authority for Child Care (NACC) | Proof of continuous care, best-interest-of-child report, clearances, counseling | 6-12 months; minimal fee |
| 5. Administrative adoption | R.A. 11642 | Prospective adoptive parents before NACC Regional Alternative Child Care Office | Home study, child case study, clearances, counseling | 9-18 months; filing fee ₱4,000 (indigent exempt) |
*Processing times vary among LCRs; values are averages as of 2025.
Important: Administrative remedies cover clerical or statutorily authorized changes only. Anything “substantial” not in R.A. 9048/9255/9858/11642 must go to court.
B. Judicial Routes (Court Petition)
| Petition | Appropriate When | Procedural Steps |
|---|---|---|
| Rule 103 – Change of Name | Child (through guardian) seeks a new surname for reasons outside R.A. 9048/9255: e.g., ridicule, naturalization, religious reasons. | (1) Verified petition in the Regional Trial Court (RTC) of province where child resides; (2) Publication in a newspaper of general circulation once a week for 3 consecutive weeks; (3) Notice to Solicitor General & Civil Registrar; (4) Hearing; (5) Decision; (6) Annotation on PSA record. |
| Rule 108 – Cancellation/Correction of Entry | Errors/substantial changes in civil-registry facts beyond clerical scope: legitimacy status, filiation, adoption decrees (before 2022), gender change (Silverio), etc. | Same as Rule 103 except petition is captioned under Rule 108; indispensable parties (OSG, LCR, parents) must be impleaded; summary proceedings allowed when uncontroverted. |
Costs: Filing fee ₱4-6 k, publication ₱8-15 k, lawyer’s fees separate. Relief often takes 6-12 months (uncontested) or longer when contested.
4. Documentary Checklist
Core documents
- PSA-issued birth certificate (latest SECPA).
- Any PSA marriage certificate (for legitimation).
- Valid IDs of petitioner(s) & child.
- Barangay certificate of residence.
Supporting evidence (case-specific)
- AUSF + father’s ID/cedula (R.A. 9255).
- DNA test, if paternity contested.
- School / medical records showing current usage of desired surname.
- Affidavits of two disinterested persons.
- Police/NBI clearances (adoption).
Procedural documents
- Notarized petition/affidavit.
- Proof of publication (for court cases).
- Registry receipts for notices to OSG/LCR.
5. Who May File and When
| Petitioner | Age/Status | Notes |
|---|---|---|
| Father/Mother | Any age (must be of legal capacity); mother’s consent always required for illegitimate child under R.A. 9255. | Father alone may not change surname of an illegitimate child without mother’s concurrence unless through court. |
| Legal Guardian | Appointed by court or designated in will. | Must show guardianship order. |
| Child | ≥ 18 years may file independently; ≥ 15 but < 18 may petition with parental assistance (sp. proc. 2023-23 guidelines). | For adoption, child aged ≥ 10 must give written consent. |
There is no prescriptive period: a petition may be filed any time; however, early action avoids complications in passports, school, and inheritance.
6. Practical Scenarios & Recommended Remedies
| Situation (2025 landscape) | Remedy & Legal Basis |
|---|---|
| Mother wants 3-year-old illegitimate child to bear father’s surname after father signs acknowledgment. | R.A. 9255 AUSF at the LCR; no court. |
| Parents married in 2022 after child’s 2018 birth; they want legitimacy & father’s surname. | Legitimation under R.A. 9858 via LCR; automatic surname change. |
| Child’s birth certificate spells “Macapagal” as “MacapagaI” (capital I for L) causing passport refusal. | Clerical correction under R.A. 9048 at LCR. |
| 12-year-old adopted via R.A. 11642 in 2024 wants adopter’s surname. | Surname automatically changed; NACC issues Order of Adoption served on PSA for annotation. |
| Mother remarries; step-father wants child to assume his surname. | Adoption (administrative or judicial, depending on domicile); surname follows adopter. |
| Child seeks to drop abusive father’s surname for mother’s. | Rule 103 petition; must allege “proper or reasonable cause” (e.g., best interests, psychological harm). |
7. Common Pitfalls
- Wrong venue – Court petition filed in city of birth, not current residence; dismissible for lack of jurisdiction.
- Failure to implead necessary parties (OSG, civil registrar, biological parent) under Rule 108 ― leads to nullity of judgment.
- Using R.A. 9048 for substantial change – LCR will deny; must go to court.
- Assuming AUSF is possible after father’s death – posthumous acknowledgment requires joint affidavit of two closest paternal relatives; if unavailable, court action needed.
- Delayed annotation – Even after a favorable judgment/administrative order, PSA will not issue an amended certificate until LCR transmits the annotated copy; follow up diligently.
8. Timelines at a Glance
| Remedy | Approx. Duration | Appealable To |
|---|---|---|
| R.A. 9048/10172 correction | 3-6 months | Civil Registrar General; then RTC via Rule 74. |
| AUSF (R.A. 9255) | 2-4 months | Civil Registrar General; then RTC. |
| Legitimation (R.A. 9858) | 1-3 months | Civil Registrar General; then RTC. |
| Administrative adoption (R.A. 11642) | 9-18 months | National Authority for Child Care’s Executive Director; then Court of Appeals on pure questions of law. |
| Judicial petition | 6-24 months | Court of Appeals; subsequently Supreme Court on certiorari. |

10. Effect of Surname Change
- Civil Registry Annotation – Only upon annotation does the change bind third parties (PSA & LCR keep both old and new entries).
- Passports & IDs – Present annotated birth certificate; DFA will issue a new passport; old passport is cancelled.
- School & Employment Records – Submit PSA-certified copy with annotation; schools and employers must update.
- Inheritance & Support – Surname per se does not alter legitimacy or successional rights except in legitimation/adoption contexts.
- Criminal Liability – Changing surname does not erase criminal records; NBI retains aliases.
11. Frequently Asked Questions
| Question | Answer (2025) |
|---|---|
| Can the child revert to the mother’s surname later? | Yes, by filing a Rule 103 petition showing valid reasons (e.g., abandonment), or by administrative recourse if erroneously processed. |
| Is father’s written consent always required? | For R.A. 9255, yes (acknowledgment). If unavailable, the mother must resort to court (Rule 103/108). |
| Does turning 18 affect the remedy? | Upon majority, the child becomes the real party-in-interest and may file or ratify a pending petition. |
| Will the PSA issue a new certificate? | PSA issues a certified transcript bearing an annotation; the old registry number remains. |
| Are online filings accepted? | Since 2023, several LCRs pilot e-Petitions under PSA Circular 2023-04; however, personal appearance for oath taking remains mandatory. |
12. Best-Practice Tips for 2025
- Secure multiple PSA certificates early; courts often require at least three certified copies.
- Verify LCR requirements; some require CENOMAR of parents for R.A. 9255 to rule out existing marriages.
- Follow up every 30 days after decision release; un-transmitted court orders are the #1 cause of PSA delays.
- Keep receipts and official letters; they prove diligence if records later go missing.
- Consult counsel for contested paternity or when publication costs can be waived (pauper litigant).

Conclusion
Changing a child’s surname in the Philippines is never a one-size-fits-all affair. The correct pathway depends on the child’s legitimacy, the nature of the desired change (clerical vs. substantial), and the presence—or absence—of parental consent. Thanks to incremental reforms (R.A. 9255, 9048, 9858, 11222, and most recently 11642), many families can now obtain relief administratively, sparing them the cost and delay of court litigation. Still, judicial recourse remains indispensable for changes outside these statutes or for contested cases.
Because each family’s facts are unique—and errors can be costly—obtaining professional advice and strictly following procedural rules is the safest way to ensure that the new surname is valid, binding, and swiftly reflected in all civil-registry records and government IDs.
