Considering change of surname in the Philippines
The user is looking for an exhaustive, legal article on changing surnames in the Philippines. The response needs to cover various bases: legal grounds (such as Civil Code, Family Code, RA 9048, RA 10172, etc.), procedures, and documents involved. It must also touch on related issues like marriage, annulment, legitimation, adoption, name corrections due to clerical errors, timelines, costs, remedies, and constitutional rights. Plus, any up-to-date court decisions and guidelines from authorities as recent as May 2025 need to be included.
Researching surname change law
To gather the most accurate and up-to-date information about surname changes in the Philippines, I need to look up recent amendments to RA 9048 and RA 10172, as well as any Supreme Court decisions and PSA guidelines. I'll craft specific searches like "RA 9048 surname change 2024" and "PSA guidelines surname change 2023". Once I have the results, I'll analyze them, ensuring I have the latest legal details about the administrative versus judicial processes for changing a surname.
Clarifying surname change laws
We need to get into more detail on RA 9048, as it primarily covers clerical errors or first name changes, but not full surname changes, which require a judicial process. For surname changes under judicial processes, rules like Rule 103 and Rule 108 apply. We also need to investigate Supreme Court decisions that clarify what constitutes a "proper and reasonable cause" for changing a surname. I'll ensure the article covers
Checking legal clarifications for surname changes
I’ll look into GR 243288 2019 to check if it clarifies RA 9048 and surname change coverage. The idea is to see whether this decision affects the law's application, though it could be behind a site block. I’ll try using a search snippet to get the info more easily. Also, PSA Administrative Order 1 Series of 2016 could help clarify RA 9255. Using these sources, I’ll cite them in the article.
Structuring legal article on surname change
I need to make sure I cover several important points, like the constitutional right to a name, relevant articles in the Civil Code, and key provisions from laws like RA 9048, RA 10172, and others. Additionally, I'll explain processes for surname changes due to marriage, legitimation, or clerical errors, and touch on issues like gender identity. I'll also address the impact on official documents and include crucial details such as costs, timelines, and requirements. Multiple citations will back up the information, ensuring thorough coverage.
Covering Key Legal Points for Surname Changes
For this article, I'll touch on important legal aspects such as the constitutional right to a name, provisions in the Civil Code about surname use in marriage, and relevant Family Code articles for children. I'll also cover the rules surrounding correcting clerical errors, legitimacy of children, simulated birth rectification, adoption laws, and how gender identity impacts surname changes. Additionally, I'll look into the costs, timelines, and the effect on documents like passports and SSS. This will be a comprehensive article!
Ensuring Proper Citation and Legal Coverage
For accuracy up to 2025, I’ll stick to core legal aspects for surname changes, citing key laws like RA 9048, RA 10172, and RA 9255, along with relevant Supreme Court cases. While I don’t need access to PDF content for this, referencing sources like the Respicio article will be useful. I’ll avoid including RA 11909 for now, as it's not relevant, and I’ll look up any potential 2024 Supreme Court decisions on surname changes.
Focusing on Key Sources and Accuracy
I don’t need to access the RA 9255 PDF since I can just cite it. The user expects a comprehensive, structured article, and I need to make sure I cover everything up to 2025. RA 11909 appears unrelated to surname changes, so I’ll avoid that. Instead, I’ll focus on the key laws and check for any relevant 2024 Supreme Court rulings, specifically regarding surname changes, by searching "surname change Supreme Court 2024 Philippines Rule 103".

Instead, I'll focus on the key laws and Supreme Court cases, including RA 9255 and Civil Code Articles 370-380. It’s important to check the latest jurisprudence, specifically for case law from 2024. I'll make sure to cite everything appropriately, ensuring accuracy up to 2025.
Focusing on Key Laws
The user likely expects a well-structured, comprehensive article. To ensure accuracy up to 2025, I’ll focus on the key laws—like RA 9255—while avoiding RA 11909 since it’s unrelated to surname changes. I should also check for any new Supreme Court decisions in 2024 that could affect surname changes.

Changing One’s Surname in the Philippines: 2025 Complete Legal Guide
1 | Why the law cares about surnames
Your surname is a legal shorthand for civil status, filiation, citizenship, property and succession rights, and even criminal liability for identity-fraud. Philippine law therefore allows a surname to be altered only in tightly defined situations and under procedures designed to prevent fraud and protect third-party interests. (RESPICIO & CO.)
2 | Sources of law you must know
| Layer | Key provisions | What they cover |
|---|---|---|
| Civil Code (1949) | Arts. 370-380, 375-377 | Married women’s options; use of “Jr.”; prohibition on unilateral change of name (Lawphil) |
| Family Code (1988) | Arts. 174-176 & 364 | Legitimate vs. illegitimate children’s surnames; effects of legitimation |
| Republic Acts | R.A. 9048 (2001) → clerical errors & first names; R.A. 10172 (2012) → extends R.A. 9048 to day/month of birth & sex markers; R.A. 9255 (2004) → lets an illegitimate child use the father’s surname by Affidavit (AUSF); R.A. 9858 (2009) → legitimation by subsequent marriage; R.A. 11222 (2019) simulated-birth rectification; R.A. 11642 (2022) administrative adoption; R.A. 11767 (2022) foundling act (Lawphil, Philippine Statistics Authority, Lawphil, RESPICIO & CO.) | |
| Rules of Court | Rule 103 (Change of Name) & Rule 108 (Cancellation/Correction of Entries) | Judicial avenue for substantial surname changes |
| PSA Administrative Orders | AO 1-2004 & AO 1-2016 (R.A. 9255); PSA AO No. 2-2023 consolidating R.A. 9048/10172 IRR | Detailed filing forms, fees, posting requirements (Philippine Statistics Authority) |
| Supreme Court jurisprudence | Republic v. CA (Hernandez), G.R. 117209 (1996); Silverio v. Republic, G.R. 174689 (2007); Jeff Cagandahan v. Civil Registrar, G.R. 166676 (2008); Francis Luigi Santos v. Republic, G.R. 250520 (2021); Ruby Cuevas Ng divorce-recognition case, G.R. 249238 (2024) | Sets the “proper and reasonable cause” test; gender-related limits; foreign divorce effects (Lawphil, Lawphil, Lawphil, Lawphil, Lawphil) |
3 | Two basic pathways
| Administrative (civil-registry) | Judicial (Regional Trial Court) | |
|---|---|---|
| When allowed | • Obvious clerical/typographical error in surname (misspellings, switched letters) under R.A. 9048/10172 • Illegitimate child adopting father’s surname via AUSF under R.A. 9255 • Surname changes that flow automatically from legitimation (R.A. 9858) or adoption/foundling laws |
• Any substantial change: choosing a brand-new surname, removing a stigma, cultural assimilation, security reasons, gender transition concerns, complex filiation questions, denial of administrative petition |
| Governing rules | PSA AOs; form + posting for 10 days; decision by Local Civil Registrar (LCR) within 5–10 days | Rule 103/108; verified petition, newspaper publication 1× wk for 3 wks; appearance of OSG/Prosecutor |
| Typical timeline & cost | 2–6 months; ₱1 700–₱3 100 (misspelling/AUSF) | 6–18 months; ₱32 000 – ₅₀ 000+ (publication + atty.) (RESPICIO & CO.) |
3.1 Administrative correction under R.A. 9048/10172
- File a verified petition (Form No. 1) with the LCR of birth or residence; overseas Filipinos may file before a Philippine Consulate.
- Post on the municipal bulletin board for 10 days.
- Decision within 5–10 days. If approved, papers go to the PSA-OCRG for annotation; the new PSA-issued birth certificate is usually available within 1–3 months.
- Fees: ₱1 000 (clerical) + notarization and PSA copy. (RESPICIO & CO.)
LIMITATION: R.A. 9048 cannot create an entirely new surname—only correct a wrongly entered one. Use Rule 103 instead. (RESPICIO & CO.)
3.2 AUSF route for illegitimate children (R.A. 9255)
Who may file: the father, mother, guardian, or the child (if of age). Documents: Affidavit to Use Surname of Father (AUSF) + father’s public acknowledgment + IDs. Fees: ₱1 500–₂ 500 LCR fee; no newspaper publication. (RESPICIO & CO., Lawphil)
3.3 Legitimation by subsequent marriage (R.A. 9858)
When unmarried parents marry each other, the child becomes legitimate by operation of law; the LCR merely annotates the birth record, switching the child’s surname to the father’s. No court case needed. (RESPICIO & CO.)
3.4 Administrative adoption & simulated-birth rectification
- R.A. 11222 (simulated birth) and R.A. 11642 (NACC-based domestic adoption) automatically produce an amended birth certificate bearing the adoptive surname once the NACC issues its Order.
- Foundlings receive a Foundling Certificate under R.A. 11767; adoption later changes the surname. (RESPICIO & CO.)
4 | Judicial avenue: Rule 103 or Rule 108
- Venue: RTC of the province where petitioner has resided for at least 3 years.
- Petition: Verified, stating grounds (ridicule, long-established use, security, best interests of child, etc.) + PSA certificates, NBI & police clearances, affidavits.
- Publication: Once a week for 3 consecutive weeks in a newspaper of general circulation.
- Hearing: Present testimony; the Solicitor General or local prosecutor cross-examines to guard against impostors and creditors.
- Decision & Annotation: After the decision becomes final (15 days), the court transmits an Entry of Judgment to the LCR and PSA for annotation.
- Appeals: 15 days to the Court of Appeals. (RESPICIO & CO., Lawphil)
Grounds accepted by the Supreme Court
| Case | Key holding |
|---|---|
| Republic v. CA (Hernandez), 1996 | “Proper and reasonable cause” standard; reputation and long-use justify change. (Lawphil) |
| Silverio v. Republic, 2007 | Court denied change of sex and name after gender-affirming surgery, ruling Congress must act first. (Lawphil) |
| Jeff Cagandahan v. Civil Registrar, 2008 | Allowed intersex petitioner with congenital adrenal hyperplasia to change sex and first name; surname unchanged. (Lawphil) |
| Francis Luigi Santos, 2021 | Re-affirmed that substantial surname change remains judicial, not administrative. (Lawphil) |
| Ruby Cuevas Ng, 2024 | After foreign divorce is judicially recognized, a former wife may resume her maiden surname under Art. 370. (Lawphil) |
5 | Surname after marriage, annulment or foreign divorce
| Scenario | Governing rule | Practical effect |
|---|---|---|
| During marriage | Art. 370 Civil Code | Wife may: (a) keep maiden name; (b) use husband’s surname; (c) use both, e.g., “Maria Cruz-Reyes.” |
| Annulment/Declaration of nullity | Art. 63(2) Family Code | Woman may revert to maiden surname once decision is final and PSA issues the annotated marriage certificate. |
| Foreign divorce (for Filipinos married to foreigners) | Recognition case under Rule 108; Ruby Cuevas Ng precedent | After recognition decree, PSA annotation lets the Filipino spouse revert to maiden surname or keep ex-spouse’s surname. (Lawphil) |
6 | Surnames of children at a glance
| Child’s status | Default surname | How to change |
|---|---|---|
| Legitimate | Father’s (or agreed compound) | Court order (e.g., Rule 103) for substantial change |
| Illegitimate | Mother’s | AUSF under R.A. 9255 if father duly acknowledges |
| Legitimated (R.A. 9858) | Father’s (after parents marry) | Annotation only |
| Adopted | Adoptive parents’ | Automatic via NACC Order (R.A. 11642) |
| Foundling | Foundling Cert. → adoptive surname | Adoption under R.A. 11642 / R.A. 11767 |
7 | After the surname is changed — updating other records
- PSA Certificate – wait for annotated copy (or new COLB) before touching any other ID.
- Passport – DFA requires the annotated PSA copy or the RTC Decision + Entry of Judgment. Processing normally allowed 2-3 weeks after PSA annotation. (RESPICIO & CO.)
- Government IDs – PhilSys, SSS, PhilHealth, BIR TIN, PRC, LTO and COMELEC each demand either the annotated PSA record or authenticated court decision. Bring several certified true copies.
- Private records – banks, schools, insurers usually accept the same documents plus valid photo ID showing the new surname.
8 | Costs & timelines (2025 pesos)
| Scenario | Government fees | Third-party costs | Total cash out-of-pocket | |
|---|---|---|---|---|
| Misspelled surname (R.A. 9048) | ₱1 000 | Notary 300 + PSA 365 | ≈ ₱1 700 | |
| Illegitimate child → father’s surname (R.A. 9255) | ₱1 500–₂ 500 | AUSF drafting 600 | ≈ ₱2 100–₃ 100 | |
| Judicial change (Rule 103) | ₱4 530 filing | Publication 8 000–15 000 + lawyer 20 000+ | ≈ ₱32 000–₅₀ 000+ | |
| Simulated-birth rectification (R.A. 11222) | ₱2 000–₃ 000 | PSA copies 500 | ≈ ₱2 500–₃ 500 | (RESPICIO & CO.) |
Indigents may file in forma pauperis; LCR and court fees are waived upon proof that family income is below the PSA poverty threshold.
9 | Recent administrative tweaks (2023 – 2025)
- PSA AO No. 2-2023 merged the separate IRRs of R.A. 9048 and 10172 and introduced an online appointment system for filing petitions. (Philippine Statistics Authority)
- e-Court roll-out in NCR and Region III lets counsel file Rule 103/108 petitions and receive notices electronically, shaving 4-6 weeks off typical timelines. (RESPICIO & CO.)
- Publication cost caps: The Supreme Court’s 2024 Bar Matter §05 reminded judges to consider cheaper provincial papers when the petitioner is indigent. (RESPICIO & CO.)
10 | Seven common pitfalls
- Using R.A. 9048 for a totally new surname – the LCR will deny it; file Rule 103 instead.
- No NBI clearance in Rule 103 petition – results in outright dismissal.
- Failure to re-stamp old IDs – passports or PRC licenses issued after the change but citing the old surname are void.
- Affidavit of Publication errors – wrong dates invalidate proof of notice; redo publication.
- Assuming gender transition alone is a ground – still requires Congress to amend the law; courts will deny unless intersex (Cagandahan).
- Skipping PSA follow-through – court/LCR approval is useless until PSA annotates the civil-registry file.
- Budget shock – in NCR the newspaper fee can exceed the court docket; always request quotes from at least three papers. (RESPICIO & CO.)
11 | FAQs
| Question | Short answer |
|---|---|
| Can I simply start using a different surname? | No; you risk perjury and invalid IDs. Do the proper procedure first. |
| How long before I can renew my passport? | 2–3 weeks after PSA issues the annotated birth/marriage certificate. |
| Is marriage a ground to force the wife to adopt the husband’s surname? | No; Art. 370 gives her the option. |
| Can a transgender Filipino change surname to match gender identity? | Only through Rule 103 and only if you meet the “proper and reasonable cause” test; Silverio still bars sex-marker change absent new legislation. |
| What if the LCR denies my petition? | Appeal to the Civil Registrar General, or switch to a Rule 103/108 court petition. |
12 | Take-aways
- Match the remedy to the goal: clerical misspelling → R.A. 9048; child’s filiation → R.A. 9255/9858; anything else → court.
- Prepare a paper trail: PSA certificates, clearances, IDs and—if going to court—proof of publication.
- Expect waiting time: even “simple” LCR actions need PSA annotation before other agencies will honour the new surname.
- When in doubt, consult counsel or the PSA Help Desk before filing; the wrong petition wastes money and months.
With these rules, costs, timelines and recent updates in mind, you can chart the correct—and legally secure—path to changing a surname in the Philippines.
