2. Default Surname Rules at Birth
| Child’s Status at Birth | Governing Rule | Default Surname |
|---|---|---|
| Legitimate (father & mother married) | Family Code Art. 174 | Father’s surname. |
| Illegitimate (parents not married) – before RA 9255 | Family Code Art. 176 (original) | Mother’s surname. |
| Illegitimate – after RA 9255 | RA 9255 §1 | Mother’s surname unless father explicitly acknowledges and both parents execute a public instrument or record the acknowledgment in the birth certificate; then child may use father’s surname. |
| Foundlings | Civil Code Art. 367; RA 11767 (Foundling Recognition) | Given a first name; surname may be chosen by finder/DSWD subject to later change once parentage is established. |
| Muslim Filipinos | PD 1083 Arts. 160–162 | Customary or Islamic naming practices; if conflict, PD 1083 prevails in Shari’a courts. |
3. Why & When a Child’s Surname May Be Changed
- Correction of clerical/typographical error (misspelling, misplaced hyphen) – RA 9048/10172.
- Switch from mother’s to father’s surname (or vice-versa) – RA 9255 or judicial petition.
- Legitimation by subsequent marriage – Family Code Arts. 177-180; RA 9858.
- Adoption (domestic, inter-country, administrative) – RA 8552, 8043, 11642; new surname of adoptive parent(s).
- Rectification of simulated birth – RA 11222 (administrative) or Rule 108 (judicial).
- Change for just and reasonable cause (e.g., ridicule, confusion, security) – Rule 103.
- Gender-affirming changes & intersex cases – Cagandahan doctrine; sex marker + given name but surname may also be sought.
- Religious or cultural reasons – e.g., double-surname or compound Hispanic names.
- Foreign domicile or recognition of foreign decree – Rule 39 §48; private international law (Art. 15 Civil Code).
4. Two Main Pathways
A. Administrative Remedies (PSA/LCR)
| Statute | What May Be Corrected/Changed | Key Steps | Decision-maker |
|---|---|---|---|
| RA 9048 (minor errors) | - Clerical/typographical errors |
- Change of first name or nickname | • Sworn petition (OCCR Form No. 1.1) filed with city/municipal civil registrar (LCR) where the birth is recorded or where petitioner resides. • Notice displayed for 10 days. | Local Civil Registrar; review by OCRG. | | RA 10172 | - Day/month of birth
- Sex (if clerical) | Same process + medical or NBI proof for sex corrections. | Same. | | RA 9255 | - Use of father’s surname by an illegitimate child | • Both parents (or mother + attested acknowledgment by father) execute an Affidavit to Use the Surname of the Father (AUSF) within child’s minority. • Attach ID, birth certificate, acknowledgment documents (e.g., Affidavit of Admission of Paternity or CRG-issued CENOMAR for father). | LCR → PSA prints an amended birth certificate. |
Timelines: 3-6 months average; shorter if documents complete. Appeal: Adverse LCR decision may be elevated to the Civil Registrar-General, then to the Court of Appeals via Rule 43.
B. Judicial Remedies (Regional Trial Court – Family Court)
| Rule | When Necessary | Procedure Highlights |
|---|---|---|
| Rule 103 – Change of Name | • Petition seeks wholesale change of surname (or given name) not covered by RA 9048 (e.g., “Juan Cruz” → “Juan de la Cruz-Reyes”). | |
| • Grounds: confusing, ridiculous, security threats, sincere religious conversion, identically named parent/sibling, habitually used name. | • Verified petition in RTC of province where petitioner resides for at least 3 years. | |
| • Publication in a newspaper of general circulation once a week for 3 consecutive weeks. | ||
| • Parties: Solicitor General/OAG, Civil Registrar. | ||
| • Judgment becomes basis for PSA annotation. | ||
| Rule 108 – Cancellation/Correction of Entries | • “Substantial” changes involving status, nationality, legitimacy, paternity, or if conflicting entries (e.g., child erroneously recorded as legitimate). | |
| • Legitimation, adoption annotation, rectification of simulated birth if not covered administratively. | • Similar verified petition but filed with RTC where civil registry is located. | |
| • Publication once a week for 3 weeks. | ||
| • All interested persons must be impleaded and served notice (parents, presumed father, PSA, NACC etc.). | ||
| • Summary hearing allowed only when facts undisputed (Republic v. Valencia). |
Tip: Courts will dismiss if petitioner “shortcut” and used RA 9048 when the change is substantial. The converse is also true; filing a Rule 103 petition for a mere typo wastes time and money.
5. Surname Change via Legitimation
- Subsequent valid marriage of parents (Art. 177).
- Legitimation by free union parents below marrying age – RA 9858 (child born while parents were < 18 yrs).
- Effect: Child is deemed legitimate ab initio and automatically bears father’s surname - PSA issues an amended birth certificate annotated “legitimated by subsequent marriage.”
- Procedure: File Joint Affidavit of Legitimation with LCR + marriage certificate + child’s birth certificate. Judicial legitimation may be filed under Rule 108 if documentary gaps exist.
6. Adoption-Driven Surname Change
| Regime | Forum | Resulting Surname | Notes |
|---|---|---|---|
| RA 11642 (Administrative Domestic Adoption) | National Authority for Child Care (NACC) | Child assumes adoptive parent’s surname; given and middle names may also be changed if requested. | Streamlined; no court hearing; PSA releases new Certificate of Live Birth (COLB). |
| RA 8552 (Judicial Domestic Adoption) | RTC - Family Court | Same. | Older cases filed before 2022 still pending under this regime. |
| RA 8043 (Inter-Country) | Inter-Country Adoption Board (ICAB) + foreign court | Philippine COLB amended upon submission of foreign adoption decree. | Surname generally that of foreign adoptive parent(s). |
| Relative Adoption | Same statutes. | May retain original surname if adopters request. | Useful for step-parent adoptions. |
7. Rectification of Simulated Birth Records (RA 11222, “Administrative Adoption for Simulated Birth Rectification”)
Simulation = registering a child as one’s own when not biologically related.
Requirements:
- Simulation done before 29 March 2019.
- Child treated as one’s own continuously.
- Best interest of the child served.
Process: File petition before NACC; after approval, PSA issues an amended COLB showing adoptive surname. No criminal liability for simulator if conditions met.
8. Grounds Judicially Accepted as “Just & Reasonable”
Illustrative but not exhaustive:
| Ground | Illustrative Case(s) |
|---|---|
| Surname causes ridicule or is obscene | In re: Jeff Chuan Wong (G.R. 98417, 1993). |
| Child has continuously used another surname in school / community | Republic v. Court of Appeals & Hernandez (G.R. 97999, 1992). |
| To avoid confusion with similarly named parent/sibling | Carlos v. Republic (G.R. 58328, 1982). |
| Threat to security / witness protection | DOJ Advisory opinions; applied in sealed court proceedings. |
| Conformity with gender identity | Republic v. Cagandahan (intersex change). |
9. Effect of Surname Change
| Aspect | Consequence |
|---|---|
| Citizenship / Legitimacy | Change does not by itself alter legitimacy or citizenship unless change stems from legitimation or adoption. |
| Succession & Support | Post-change, rights follow new status (legitimate/adopted). |
| Public & Private Records | PSA issues annotated or amended birth certificate; all other IDs (passport, PhilSys ID, school records, SSS, PhilHealth, bank) must be updated. |
| Travel | Passport renewal requires PSA-issued COLB and the court/administrative order. |
| Marital Consent in Future | For minors, both parents (or new legal parents after adoption) must sign passport or travel authority applications. |
10. Procedural Checklist (Quick Reference)
| Step | Administrative Path (RA 9048 / 9255) | Judicial Path (Rule 103/108) |
|---|---|---|
| 1. Decide correct remedy | Check PSA “Matrix of Changes” | Assess if change affects status/substantial rights |
| 2. Prepare documents | • Sworn petition/AUSF | |
| • IDs of parents | ||
| • Birth certificate (SECPA) | ||
| • Supporting proofs | • Verified petition | |
| • PSA documents | ||
| • Affidavits, baptismal/school records | ||
| • Draft order of publication | ||
| 3. File | Local Civil Registrar (residence or place of birth) | RTC-Family Court (residence or place of registry) |
| 4. Notice | Post for 10 days (LCR) | Publish 3 weeks in newspaper; serve personally on interested parties |
| 5. Hearing / Evaluation | LCR evaluates; may summon parties | Court pre-trial; reception of evidence |
| 6. Decision | LCR decision → CRG approval → Annotation | Court decree → final & executory in 15 days |
| 7. PSA Annotation | Submit decision to PSA | Same |
| 8. Update other agencies | DFA, DepEd/CHED, COMELEC, SSS, banks, etc. | Same |
11. Special Populations & Situations
- Muslim & IP communities – Shari’a Circuit Courts or NCIP guidelines may supersede if customary law invoked.
- Child in Conflict with the Law / Trafficking Victims – Surname change can aid reintegration but must respect confidentiality provisions of RA 9344 & RA 9208.
- Dual Citizens & Foreign-Born Filipinos – Need Philippine-registered birth via Report of Birth before LCR/PSA will annotate any foreign decree.
12. Common Pitfalls
- Using the wrong remedy – A clerical error petition won’t fix an issue of legitimacy.
- Omitting indispensable parties – Leads to nullity of Rule 108 judgments.
- Publication lapses – Courts strictly require proof of proper publication.
- Late AUSF filing – After the child reaches 18, RA 9255 relief must be sought in court.
- Assuming surname change = name change everywhere – Separate updates needed for each government agency.
13. Practical Timeline Estimates (2025)
| Remedy | Metro Manila | Provinces |
|---|---|---|
| Minor clerical correction | 2 – 4 months | 3 – 6 months |
| AUSF under RA 9255 | 1 – 3 months | 2 – 4 months |
| Rule 103 petition | 6 – 12 months | 4 – 10 months |
| Rule 108 complex case (legitimation, simulation) | 12 – 18 months | 8 – 16 months |
| Administrative adoption (RA 11642) | 6 – 9 months nationwide |
Timelines assume complete documents and no opposition.
14. Fees (indicative, 2025)**
| Item | Amount (₱) | Notes |
|---|---|---|
| RA 9048 / 10172 filing fee | 1,000 – 3,000 | Depends on city class; plus ₱1,000 CRG fee. |

15. Key Take-Aways
- Identify the correct legal path: clerical vs substantial; administrative vs judicial.
- Gather complete documentary proof early—delays usually stem from missing files.
- Observe due process: notice, publication, inclusion of all indispensable parties.
- Understand downstream effects on legitimacy, inheritance, and travel documentation.
- Consult competent counsel or the PSA Help Desk for nuanced or contested cases.
