Changing a Child’s Surname from the Father’s to the Mother’s in the Philippines A comprehensive legal guide (updated to July 2025)
1. Key Take-aways
| What you want to do | Fastest lawful path | Typical time-frame* | Core legal basis |
|---|---|---|---|
| Illegitimate child was registered with the father’s surname without the RA 9255 affidavit of acknowledgment & consent | Administrative correction before the local civil registrar (LCR) under R.A. 9048 (clerical error) | 3–5 months | R.A. 9255, R.A. 9048, PSA/LCRO Implementing Rules |
| Illegitimate child properly acknowledged under RA 9255 but now wishes to carry the mother’s surname | Judicial petition for change of name (Rule 103) OR correction of entry (Rule 108) in the RTC | 6 months–2 years | Art. 376 Civil Code, Rule 103/108, jurisprudence |
| Legitimate child (parents married) seeks to drop father’s surname | Judicial petition (Rule 103) - purely discretionary | 6 months–2 years | Art. 174–176 Family Code, Art. 376 Civil Code |
| Adult wishes to replace father’s surname with mother’s | Same as above—file own Rule 103 petition in RTC where domiciled | 6 months–2 years | Art. 376, Rule 103 |
*Publication, court congestion and PSA processing are the biggest variables.
2. Fundamental Principles on Filipino Surnames
A child’s surname forms part of civil status—it affects filiation, citizenship, inheritance, and even criminal liability (Art. 365 Civil Code).
No person may change a surname or first name without lawful authority (Art. 376 Civil Code).
Administrative vs. judicial remedies
- Administrative (R.A. 9048 as amended by R.A. 10172) is limited to (a) obvious clerical/typographical errors, (b) change of first name/nickname, (c) correction of day/month of birth or sex. Changing a surname is not covered unless the entry was void to begin with (e.g., an illegitimate child’s certificate carried the father’s surname without the paperwork required by R.A. 9255).
- Judicial (Rules 103 & 108) is the normal path for any genuine change of surname, whether minor or adult, legitimate or illegitimate.
3. Governing Statutes, Rules and Key Cases
| Instrument | What it says about surnames |
|---|---|
| Civil Code (Arts. 364–380) | Basic rules on legitimate/illegitimate children’s surnames and prohibition on unilateral changes. |
| Family Code (Arts. 174–176) | Re-states that legitimate children bear the father’s surname; illegitimate children bear the mother’s, unless the father acknowledges under R.A. 9255. |
| R.A. 9255 (2004) | Gave an illegitimate child the option to use the father’s surname upon the father’s public acknowledgment + mother’s written consent filed with the LCR. |
| R.A. 9048 (2001) & R.A. 10172 (2012) | Created the administrative correction system. Surname changes are generally excluded, but “erroneous use of the father’s surname without RA 9255 compliance” is treated as a clerical error that can be corrected administratively. |
| R.A. 9858 (2009) | Legitimation of children born to parents subsequently married—child becomes legitimate and keeps the father’s surname automatically. |
| R.A. 11222 (2019) | Rectifies simulated births; part of the rectification is rewriting the child’s birth record (including surname). |
| Rules 103 & 108 of the Rules of Court | Provide the judicial mechanics: verified petition, publication in a newspaper of general circulation once a week for 3 consecutive weeks, notice to the civil registrar & OSG, and full-blown hearing. |
| Landmark jurisprudence | Republic v. Court of Appeals & Uy (G.R. No. 124758, 27 Nov 1998) — abandonment by father is valid ground; Bien v. Republic (G.R. No. 206006, 03 Feb 2016) — dropping father’s surname may be allowed if no RA 9255 compliance; Silverio v. Republic (G.R. No. 174689, 22 Oct 2007) — Rule 103 vs Rule 108 demarcation. |
4. Common Scenarios and Correct Path
Illegitimate child, father disappeared, registration used father’s surname without RA 9255 docs File: administrative petition (R.A. 9048) → supply PSA-issued birth certificate, mother’s ID, affidavit explaining lack of RA 9255 ATR (Affidavit to Use Father’s Surname) → LCR decision → transmit to PSA for annotation → new certificate issued.
Illegitimate child properly acknowledged under RA 9255 but later wishes to use mother’s surname File: Rule 103 petition (RTC of province/city where child resides). Required grounds accepted by courts include: best interest of child, abandonment, emotional/psychological harm, or proof that continued use of father’s surname is prejudicial.
Legitimate child wants mother’s surname (parents separated, father convicted, etc.) Courts apply strict scrutiny; mere family conflict is insufficient. You must prove “proper and reasonable cause” under Art. 376 plus jurisprudential grounds (e.g., surname is infamous, causes confusion, or child’s welfare demands it).
Adult individual (21 +) electing the mother’s surname Same Rule 103 mechanics, except petitioner files in his or her own name; no parental consent required.
5. Step-by-Step: Judicial Petition (Rule 103 / 108)
| Stage | What happens | Practical tip |
|---|---|---|
| 1. Draft & file verified petition in the RTC of the province/city where the petitioner has been resident for at least 3 years (Rule 103, §1). Attach PSA birth certificate, IDs, affidavits, clearances (NBI, police, barangay). | Filing fees - about ₱3 000–₱5 000 (varies). | Make sure petition (a) states facts, (b) cites specific grounds, (c) prays for authorization to change entries in civil registry. |
| 2. Order of Hearing & Publication | Court issues an order directing publication once a week for 3 consecutive weeks in a newspaper of general circulation. | Publication costs ₱8 000–₱20 000; ask the sheriff for list of accredited papers. |
| 3. Service on OSG & Civil Registrar | The OSG represents the State; the LCR/PSA may oppose. | Keep proof of service. |
| 4. Hearing | Present testimony: the petitioner, mother (if minor), psychologist/social worker (if welfare issues), plus documentary evidence of abandonment, non-support, etc. | Courts look for “good faith and compelling reason.” |
| 5. Decision & Finality | If granted, the decision becomes final after 15 days. Certified copy is served on the LCR/PSA for annotation. | Secure at least 4–5 certified copies; you’ll need one for each government ID/passport agency. |
| 6. PSA annotation & new copies | PSA typically issues the annotated birth certificate 4–6 weeks after receiving the decision & LCR compliance report. | Follow up religiously—delays often stem from missing transmittals. |
6. Administrative Path (R.A. 9048 / 10172) for “Erroneous Father’s Surname”
- Scope check – The LCR will entertain the petition only if the father’s surname appears without the notarized ATR (Affidavit to Use Father’s Surname) + father’s ID, as required by RA 9255.
- File verified petition (Form No. 1.19) with supporting documentary proof and sworn explanation.
- Posting – The petition is posted on the LCR bulletin board for 10 days.
- Decision – The civil registrar or PSA-authorized city/municipal registrar decides within 5 days after posting.
- Appeal – Aggrieved party or OSG may appeal to the Civil Registrar General or to court.
7. Accepted Grounds for Judicial Change of Surname (as distilled from jurisprudence)
| Ground | Illustrative cases / notes |
|---|---|
| The surname is ridiculous, dishonorable, or extremely difficult to write or pronounce. | Dauer v. Republic (G.R. L-1548, 1950). |
| The change avoids confusion (identical names within family or locale). | Yu v. Republic (G.R. L-6062, 1953). |
| The father has abandoned or neglected the child, or parent-child relationship severely impaired. | Republic v. CA & Uy (1998); Bien v. Republic (2016). |
| Child’s best interest and welfare demonstrably furthered (psychological studies, social worker reports). | Numerous family-court rulings since 2010; principle codified in A.M. No. 03-04-04-SC (Rule on Children). |
| The petitioner has continuously used the mother’s surname in good faith and has become known by it (identity stability). | Republic v. Hernandez (G.R. No. 213508, 2020). |
| Security / protection (e.g., witness-protection transferee). | Courts grant ex parte, but order is sealed. |
8. Effect on Filiation, Legitimation and Succession
- Changing the surname does not sever filiation. The father remains the legal father unless paternity is separately disestablished.
- Legitimation (R.A. 9858) automatically confers legitimacy and keeps the father’s surname. A later petition to adopt the mother’s surname is still possible but must comply with Rule 103.
- Succession rights remain intact; the child continues to inherit from the father even after adopting the mother’s surname, unless filiation is disproved in a separate proceeding.
9. Updating Government Records After the Court/LCR Order
- PSA Birth Certificate – obtain new SECPA copies.
- Passport & PhilID – DFA requires (a) PSA copy with annotation, (b) original court/LCR order, (c) two IDs in new name or combination of old and new.
- GSIS/SSS, PhilHealth, Pag-IBIG, BIR, COMELEC – each agency accepts the PSA-annotated certificate plus the court/LCR order.
- School records – submit DepEd Order 19-2020 guidelines (for K-12) or CHED Memo 2019-05 (for Higher Ed).
- Bank & private contracts – rely on the same PSA + government IDs.
10. Frequently Asked Questions
| Question | Short answer |
|---|---|
| Can the father block the petition? | Yes, he is a necessary party and may oppose. Courts will weigh his objection against the child’s welfare. |
| Is DNA testing required? | Only if paternity itself is disputed. Surname change alone usually hinges on abandonment or welfare. |
| What if the child is already 18? | The child files the petition personally; parental consent is unnecessary. |
| Do I need a lawyer? | Administrative petitions can be pro se; judicial petitions practically require counsel because of publication, pleadings, evidence, and trial skills. |
| Is publication always needed? | Yes for Rule 103/108; no for R.A. 9048 petitions. |
| Will the new surname appear on diplomas already issued? | Universities rarely re-print diplomas; they annotate records instead. Show the court/LCR order alongside the diploma when needed. |
11. Practical Timeline Example (Judicial)

12. Cost Checklist (indicative, Metro Manila 2025)
| Item | Typical amount |
|---|---|
| Filing fees (RTC) | ₱3 000–₱5 000 |
| Newspaper publication (3 weeks) | ₱8 000–₱20 000 |
| Lawyer’s professional fees | ₱40 000–₱120 000 (varies) |
| PSA copies, notarials, clearances | ₱2 000–₱5 000 |
13. Ethical & Strategic Notes for Counsel
- Best-interest standard remains the linchpin. Equip the petition with social-worker or psychologist reports wherever abandonment or emotional harm is alleged.
- Avoid forum shopping: Rule 103 petitions are in rem; any foreign divorce, adoption or recognition proceedings must be disclosed.
- Publication defects are fatal; always cross-check the newspaper’s certificate of publication for exact dates.
- Coordinate with the OSG early—pre-hearing conferences sometimes lead to a stipulation of facts and faster resolution.
14. Conclusion
While R.A. 9048 streamlined many civil-registry corrections, changing a child’s surname from the father’s to the mother’s remains primarily a judicial act except in the narrow case where the father’s surname was recorded without compliance with R.A. 9255. Courts will grant the change when proper and reasonable cause clearly outweighs the State’s interest in stability of names and records—particularly where the child’s moral, emotional, or psychological welfare is at stake.
Always begin by examining the birth certificate and the circumstances of registration. If the record is facially invalid under R.A. 9255, the administrative route will save time and money. Otherwise, prepare for a full Rule 103 (or combined Rule 108) petition: budget realistically, marshal documentary proof, address the OSG’s probable objections in advance, and keep every agency in the loop once the decision becomes final.
