In the Philippines, the name and surname of a person are matters of public interest. Because these identifiers appear in the Civil Register, they cannot be changed through mere whim or agreement between parties. Altering a child’s name or surname requires a specific legal process—either administrative or judicial—depending on the nature of the change and the child’s legitimacy status.
1. Correcting the First Name (Administrative Process)
Under Republic Act No. 9048, as amended by R.A. No. 10172, the City or Municipal Civil Registrar (C/MCR) has the authority to entertain petitions for a change of first name without a court order.
Grounds for Changing a First Name:
- The name is ridiculous, tainted with dishonor, or extremely difficult to write or pronounce.
- The new first name has been habitually and continuously used by the petitioner, and they have been publicly known by that name in the community.
- The change is necessary to avoid confusion.
Requirement for Clerical Errors:
R.A. 10172 also allows for the correction of clerical or typographical errors in the day and month of birth or the sex of the child, provided the correction is supported by medical records and a certification from a government physician.
2. Changing the Surname (Judicial Process)
Unlike first names, changing a surname generally requires a judicial petition filed under Rule 103 of the Rules of Court (Change of Name). This is a "proceeding in rem," meaning it is an action against the whole world and requires publication in a newspaper of general circulation.
Valid Grounds for Judicial Change of Surname:
- When the name is ridiculous, causes embarrassment, or is extremely difficult to pronounce.
- When the change is a result of a change in status (e.g., a child is legitimated).
- To avoid confusion.
- When a child was christened with a name they have used since childhood, and they seek to formalize it.
3. Surnames of Children Based on Legitimacy
The rules regarding which surname a child may use are strictly governed by the Family Code and Republic Act No. 9255.
Legitimate Children
Legitimate children shall principally use the surname of the father. They may also use the mother's surname as a middle name.
Illegitimate Children
Under R.A. 9255, illegitimate children shall use the surname of the mother. However, they may use the surname of the father if:
- The father has acknowledged the child through an Affidavit of Admission of Paternity.
- The father has acknowledged the child through a private handwritten instrument.
If the father has not acknowledged the child, the child must use the mother’s surname. A petition to change the surname to the father's after birth requires the filing of the aforementioned affidavit with the Local Civil Registry.
4. The Impact of Adoption
When a child is legally adopted, their surname is changed to that of the adopter as a matter of law. The Domestic Administrative Adoption and Alternative Child Care Act (R.A. 11642) now streamlines this process, allowing for the change of name to be part of the administrative adoption decree issued by the National Authority for Child Care (NACC), rather than requiring a separate court case.
5. Procedural Requirements for Petitions
Whether the process is administrative or judicial, the following documents are typically required:
Administrative (R.A. 9048/10172):
- Birth Certificate on Security Paper (PSA).
- At least two public or private documents showing the correct name (e.g., baptismal certificate, school records, medical records).
- NBI Clearance and Police Clearance (to ensure the change is not intended to evade criminal liability).
- Affidavits of publication.
Judicial (Rule 103):
- Venue: The petition must be filed in the Regional Trial Court (RTC) of the province where the child resides.
- Publication: The court will issue an order setting the case for hearing, which must be published once a week for three consecutive weeks in a newspaper of general circulation.
- Participation of the State: The Office of the Solicitor General (OSG) or the City Prosecutor will represent the interests of the State to ensure the petition is meritorious and not fraudulent.
6. Summary Table of Remedies
| Situation | Governing Law | Forum |
|---|---|---|
| Correction of misspelled first name | R.A. 9048 | Local Civil Registrar |
| Change of first name (e.g., "Boy" to "Juan") | R.A. 9048 | Local Civil Registrar |
| Correction of sex or birth date | R.A. 10172 | Local Civil Registrar |
| Illegitimate child taking Father's surname | R.A. 9255 | Local Civil Registrar |
| Substantial change of surname | Rule 103 | Regional Trial Court |
| Name change due to Adoption | R.A. 11642 | NACC / Administrative |
Note on Middle Names: In the Philippines, the "middle name" is traditionally the mother's maiden surname. There is currently no administrative process to change a middle name; substantial changes to a middle name typically require a judicial petition under Rule 103.
