How do I correct a wrong birthdate or sex on my birth certificate (RA 10172)?
Last updated: 2026-07-12 · Educational content; not legal advice.
Short answer
RA 10172 (2012), which amended RA 9048, lets the Local Civil Registrar correct a clerical/typographical error in the DAY and MONTH of your date of birth, or in the sex/gender entry, without a court order. The YEAR of birth is NOT covered — correcting the year still needs a judicial petition under Rule 108 in the Regional Trial Court. A sex correction under RA 10172 additionally requires a medical certification (from an accredited government physician) that you have not undergone a sex change or transplant. You file a verified petition at the LCR, meet the posting requirement, and pay the filing fee.

Frequently asked
Can I fix a wrong birth YEAR administratively?
No. RA 10172 covers only a clerical error in the day and month of birth, not the year. Correcting the year of birth (a substantial change) requires a judicial petition under Rule 108 in the Regional Trial Court.
What do I need to correct a wrong sex entry?
RA 10172 allows correcting a clerical error in the sex entry, but it additionally requires a medical certification from an accredited government physician that you have not undergone a sex change or sex-transplant operation, plus the usual posting of the petition.
Which law applies to my error?
A misspelled name or a change of first name falls under RA 9048; a wrong day/month of birth or a wrong sex entry falls under RA 10172. Both are administrative at the Local Civil Registry. A wrong year, surname, age, nationality, or status is judicial (Rule 108).
