Correcting a Misspelled Last Name in a PSA Birth Certificate (Philippines)

General legal information. For case-specific advice, consult your Local Civil Registry Office (LCRO) or a lawyer.

Snapshot: which path fits your case?

Simple typo in the last name (e.g., Garcai → Garcia): Proceed with administrative correction of clerical/typographical error under R.A. 9048 (as amended by R.A. 10172).
You want to change the last name to a different surname (not a mere typo), or the wrong surname was used due to filiation/legitimacy issues: This is generally a substantial correction requiring court proceedings (Rule 103/Rule 108), unless it’s about an illegitimate child using the father’s surname—then see R.A. 9255 (administrative, with specific proofs).
Month/day/sex corrections are governed by R.A. 10172 (but that’s separate from last-name spelling).

Legal bases and what they allow

R.A. 9048 (Clerical Error Law), as amended by R.A. 10172
- Administrative (no court case) correction of clerical/typographical errors in civil registry entries, including the last name if it’s plainly a clerical mistake.
- Also allows change of first name/nickname (with publication and substantial justification).
- For clerical last-name misspellings, no publication is required; posting is required.
R.A. 9255 and its implementing rules
- Lets an illegitimate child use the father’s surname administratively, if legal prerequisites (e.g., Acknowledgment/Admission of Paternity) are met. Uses an Affidavit to Use the Surname of the Father (AUSF).
Rule 103 / Rule 108 of the Rules of Court
- Judicial (court) route for change of name or substantial corrections (e.g., switching to an entirely different surname, correcting paternity/maternity disputes, legitimacy, or entries affecting civil status/citizenship).

Determine your correct route: a practical decision tree

Is it obviously a typo?
- Letters transposed/missing, wrong letter, or a clear spelling slip (e.g., Dela Crua → Dela Cruz).
- Route: R.A. 9048 clerical error correction (administrative).
Is the surname wrong because it used the wrong parent’s surname, or you want to adopt a different surname (not a misspelling)?
- Route: Generally court (Rule 103/108).
- Exception: If illegitimate and father acknowledges paternity under R.A. 9255, you may proceed administratively via AUSF.
Are there disputes about filiation, legitimacy, or identity?
- Route: Court action (Rule 108) to settle disputed facts, then annotate.

Where to file

Primary: LCRO where the birth was registered (where the civil registry record is kept).
Alternative: Your place of residence LCRO may accept and forward to the LCRO of record (check local practice).
If residing/working abroad: File with the Philippine Embassy/Consulate having civil registry functions (they transmit to the PSA/LCRO).

Who may file

The registrant (if of age).
If minor, a parent or guardian.
If deceased, the spouse, children, parents, siblings, grandparents, or a person legally authorized in writing.

Core documentary requirements (clerical misspelling of last name)

Bring originals for comparison and submit clear copies.

Filled-out Petition (R.A. 9048 form for Correction of Clerical/Typographical Error).
Latest PSA copy of the birth certificate (SECPA).
At least two to three corroborating documents showing the correct spelling of the last name, typically:
- Baptismal/Church record (if available)
- School records (Form 137, diplomas, enrollment records)
- Medical/hospital records at birth, or immunization card
- Government-issued IDs (PhilID, passport, UMID, etc.)
- Parents’ PSA marriage certificate and/or parents’ IDs
- Barangay certification attesting to identity and name usage
Affidavit of Discrepancy (narrates the error and consistent use of the correct surname).
Supporting IDs of the petitioner and proof of relationship (if filing for a minor or deceased person).
Other papers the LCRO may reasonably require for verification.

For AUSF (R.A. 9255): Add Acknowledgment/Admission of Paternity (e.g., father’s name in the birth certificate at the time of registration, a duly executed public document/private handwritten instrument, or subsequent acknowledgment in compliance with rules), the father’s IDs, and the mother’s consent if the child is a minor.

Fees (typical practice)

Clerical/typographical correction (R.A. 9048): An LCRO filing fee (often modest) and documentary stamps.
Change of first name (R.A. 9048): Higher fee plus publication cost (not applicable to clerical last-name typo).
Consular filings: May have consular fees.
Expect separate PSA copy fees for the annotated certificate later.

(Local amounts vary; confirm with your LCRO or consulate cashier.)

Process overview (R.A. 9048 clerical last-name typo)

File the Petition with the LCRO (or consulate). Pay fees; get a receiving copy.
Evaluation & records verification by the civil registrar (may request additional proofs).
Posting (notarized Notice posted at the LCRO for a set period; no newspaper publication for clerical errors).
Decision/Action by the City/Municipal Civil Registrar (or Consular Officer) approving/denying the petition.
Endorsement to PSA for annotation of the civil registry record.
Release of annotated PSA copy (request new PSA-certified copy; the margin will show the annotation describing the correction).

Keep your LCRO decision/approval, receipts, and acknowledgments; they’re useful for follow-on updates (school, passport, bank, BIR/SSS/PhilHealth, etc.).

Process overview (R.A. 9255 AUSF scenario)

Assess eligibility: Child is illegitimate; father acknowledged paternity per rules.
Execute AUSF (standard form at LCRO/consulate), with mother’s consent if the child is a minor.
Submit proofs of acknowledgment, IDs, and supporting documents.
Registrar’s evaluation and annotation; PSA issues a copy reflecting the father’s surname with a margin annotation.

If paternity is contested or proofs are insufficient, you will likely need a court petition (Rule 108).

When you must go to court instead

The change is not a clerical misspelling (e.g., Santos → Cruz without R.A. 9255 basis).
There is a dispute over identity, filiation, or legitimacy, or you need to establish paternity/maternity.
You seek relief outside what R.A. 9048/9255 allows (e.g., change for personal preference).
Prior administrative petition was denied on grounds requiring judicial determination.

Judicial route basics: Verified petition in the proper RTC; publication and hearing; presentation of evidence; court decree; LCRO/PSA annotation after finality.

Practical tips for a smooth correction

Over-document: Provide multiple independent records that consistently show the correct spelling over time.
Explain the error clearly in your affidavit (who noticed, when, and how it happened at registration or transcription).
Check other civil records (parents’ marriage certificate, your siblings’ records) and prepare copies—registrars look for consistency.
Coordinate with downstream agencies: After you get the annotated PSA, update PhilID, passport, SSS, GSIS, Pag-IBIG, PhilHealth, PRC, LTO, BIR, bank, school, and employer records.
Mind minors’ consent rules: Parents/guardians act for minors; children 18+ file for themselves.
Keep all receipts and decisions: They prove the lawful basis of the correction and speed up later transactions.

Frequently asked scenarios

Q: The last name on the PSA birth certificate is “Delacruz” but all my IDs and school records say “Dela Cruz.” A: That’s typically a clerical misspelling (spacing issue). File under R.A. 9048 with corroborating documents showing your long-standing use of “Dela Cruz.”

Q: My child was registered with my mother’s surname by mistake; we intended to use my surname. A: If this alters filiation rather than just spelling, expect a court petition—unless the case falls under R.A. 9255 (illegitimate child using father’s surname with proper acknowledgment), which can be administrative.

Q: My surname is “Ñuñez” but the certificate shows “Nunez.” A: If it’s a diacritic/character issue reflecting a clerical limitation, you may seek clerical correction under R.A. 9048, backed by consistent records.

Q: The hospital clerk misspelled our family name on late registration. A: Still R.A. 9048 clerical if the intent and evidence are clear; attach hospital records, prenatal cards, barangay certification, and parents’ IDs.

Q: Will I need newspaper publication? A: Not for a clerical error in the last name. Publication is required for change of first name petitions; posting at the LCRO is the norm for clerical corrections.

Bottom line

Clerical last-name misspellings are fixable administratively under R.A. 9048—gather solid, consistent documents and file at the LCRO (or consulate).

After approval, secure your annotated PSA and promptly update all government and private records to prevent future mismatches.
