The birth certificate issued by the Philippine Statistics Authority (formerly NSO) is the primary documentary evidence of a person’s identity, filiation, and citizenship. Errors in the registered name—whether in the first name, middle name, surname, or spelling—can cause serious problems in school enrollment, employment, passport applications, marriage, and other civil transactions.

Fortunately, Philippine law provides several administrative and judicial remedies to correct such errors, depending on the nature and gravity of the mistake. The governing laws are Republic Act No. 9048 (2001), as amended by Republic Act No. 10172 (2012), and Rules 3 and 8 of Administrative Order No. 1, Series of 2001 (IRR of R.A. 9048), supplemented by the Rules of Court for judicial proceedings.

I. Classification of Name Errors

Philippine jurisprudence and PSA practice classify name errors into two broad categories:

Clerical or typographical errors – simple mistakes that are clearly evident from the face of the birth certificate and other entries in the civil registry (e.g., “Jhon” instead of “John,” “Mariel” instead of “Marie,” missing accent marks, wrong gender marker that affects the name, interchange of first name and surname, etc.).
Substantial or material errors – changes that affect civil status, filiation, nationality, or involve a complete change of name (e.g., changing “José Cruz” to “José Santos,” changing “Maria Clara Santos” to “Maria Clara Reyes” because of subsequent legitimation or adoption, changing the entire name because the registered name is ridiculous or dishonorable, etc.).

II. Administrative Correction (No Court Action Required)

A. R.A. 9048 as amended by R.A. 10172 – Clerical Error Law

Scope (as of 2025, no further amendments):

Correction of clerical or typographical errors in the day and month of birth (R.A. 10172)
Correction of clerical errors in sex/gender
Correction of first name or nickname
Correction of clerical errors in any other entry (including spelling of names)

Who may file:

The document owner (if of legal age)
Owner’s spouse, children, parents, siblings, grandparents, guardian, or any person duly authorized by law or by the owner

Where to file:

Local Civil Registry Office (LCRO) of the city/municipality where the birth was registered, OR
Philippine Consulate if the petitioner is abroad (migrant petition)

Requirements (standard):

Certified true copy of the PSA birth certificate with the error
At least two (2) public or private documents showing the correct entry (baptismal certificate, school records, voter’s registration, GSIS/SSS, medical records, business records, driver’s license, etc.)
Affidavit of petitioner explaining the error
Earliest school record or medical record (if available)
Affidavit of two disinterested persons (for certain cases)
Proof of payment of fees (P1,000 for local filing, P3,000 if change of first name or correction of sex; US$50 abroad)

Processing time: 15–30 working days for simple cases; longer if the LCRO needs to conduct further verification.

Appeal: If the City/Municipal Civil Registrar denies the petition, an appeal may be filed with the Civil Registrar General (PSA) within 10 days.

Advantages of R.A. 9048/10172:

No need to go to court
Faster and cheaper
The corrected birth certificate is annotated only with “Corrected pursuant to R.A. 9048/10172” (no mention of court order)

Limitations:

Cannot be used for substantial changes in name (e.g., change of surname because of adoption, legitimation, or acknowledgment)
Cannot correct errors that are not “clerical” (e.g., the registered name is completely different from the true name because the child was registered under another person’s name)

III. Judicial Correction

A. Rule 108, Rules of Court – Cancellation or Correction of Entries in the Civil Registry
(For substantial changes and clerical errors that fall outside R.A. 9048/10172)

When to use Rule 108:

Change of full name or surname due to adoption, legitimation, acknowledgment, or election of citizenship
The registered name is entirely different from the real name (e.g., child was registered as “Baby Boy” or under the name of another person)
Change of surname of a foundling or a person with a dishonorable or ridiculous name
Any correction that the Civil Registrar General or the LCRO refuses under R.A. 9048

Venue: Regional Trial Court (Family Court preferred) of the province or city where the corresponding LCRO is located.

Procedure (summary):

File a verified petition setting forth the facts and the correct entries sought.
The court sets the case for hearing and orders the publication of the order once a week for three consecutive weeks in a newspaper of general circulation.
The following must be notified and furnished copies:
- Civil Registrar concerned
- PSA (Civil Registrar General)
- Any other person who may have interest
Trial ensues. Petitioner must prove:
- The error is not clerical or, if clerical, cannot be corrected administratively
- The correction sought is justified and will not prejudice third parties
If granted, the court issues an order directing the LCRO to correct the entry.
The decision becomes final after 15 days if no appeal is filed.
Petitioner submits the Entry of Judgment and the court order to the LCRO and PSA for annotation.

Landmark cases:

Republic v. Valencia (G.R. No. L-32181, 1975) – first name may be changed if ridiculous or extremely difficult to pronounce.
Republic v. Marcos (G.R. No. 170116, 2009) – change of name is a privilege, not a right.
Onde v. Republic (G.R. No. 213596, 2018) – correction of surname due to legitimation may be done via Rule 108.
Republic v. Tipay (G.R. No. 209527, 2017) – correction of completely wrong name registered by hospital personnel is allowed under Rule 108.

B. R.A. 9255 – Acknowledgment / Legitimation Cases
If the child was originally registered under the mother’s surname and the father later acknowledges the child (via public document or private handwritten instrument with father’s signature), the surname may be changed to the father’s surname via Rule 108 or, in some cases, administratively if the LCRO accepts it.

C. Adoption Cases
Domestic adoption (R.A. 8552) and inter-country adoption (R.A. 8043) automatically result in issuance of a new PSA birth certificate bearing the adoptive parents’ surname and the new name of the child, if changed. No separate correction proceeding is needed.

IV. Special Cases

Situation	Proper Remedy
Spelling error in first name (Jon vs. John)	R.A. 9048 (administrative)
Complete change of first name (Maria to Sophia) because it is dishonorable	Rule 108 (judicial)
Child registered as “Baby Boy” or wrong name	Rule 108
Change of surname due to legitimation/acknowledgment	Usually Rule 108 (or R.A. 9255 affidavit + Rule 108)
Sex/gender marker error (Male instead of Female)	R.A. 10172 (administrative)
Day and month of birth wrong	R.A. 10172 (administrative)
Foundling wanting to change name	Rule 108

V. Practical Tips

Always start with R.A. 9048/10172 if the error appears clerical. It is faster and cheaper.
Secure as many supporting documents as possible (baptismal, Form 137, voter’s cert, NBI clearance, etc.).
If the birth was registered very late (delayed registration), substantial corrections are almost always judicial.
PSA will annotate the corrected certificate with either “Corrected pursuant to R.A. 9048/10172” or “Annotated per Court Order dated ___ in Civil Case No. ___”.
Once corrected, the old erroneous version is suppressed; only the corrected version is issued to the public.

Correcting name errors in a PSA birth certificate is almost always possible under Philippine law. The choice between the administrative route (R.A. 9048/10172) and the judicial route (Rule 108) depends on whether the mistake is merely clerical or involves a substantial change in identity or status. With proper documentation and adherence to procedure, the civil registry can be brought into conformity with reality, allowing the person to use his or her true and correct name in all legal transactions.
