The Short Answer
Go to the civil registry at your city or town hall. Under the law, the civil registrar can fix an obvious typing or spelling mistake, change a first name for allowed reasons, and correct a wrong day or month of birth or a wrong sex entry that was plainly a typing mistake. You file a sworn petition (a written request signed under oath) and show other records with the correct entry. A wrong year of birth, a different surname, or anything that changes your status needs a court case.
Example: A Nurse Bound for Saudi Arabia
Names and details in this example are made up.
Kristine Joy Mendoza was born on 14 September 1998 in Barangay Poblacion, Lucena City, Quezon. In 2026 she gets a job offer as a nurse in Riyadh. When she requests her PSA Birth Certificate for her DMW papers, she sees two mistakes: her first name is typed "Kristine Jay", and her birthday reads 14 November 1998. Her school records, Baptismal Certificate, PRC License and voter's record all say Kristine Joy, born 14 September 1998.
Mistake 1: "Jay" for "Joy". This is a clerical (typing) error. It is obvious, harmless, and can be checked against her other records. She files a petition for correction of clerical error under Republic Act No. 9048 (RA 9048). PSA lists the fee at the local civil registry as ₱1,000.
Mistake 2: November instead of September. A wrong month of birth is covered by Republic Act No. 10172 (RA 10172), as long as it is plainly a clerical mistake. She files a separate petition. PSA lists the fee as ₱3,000. This one must also be published in a newspaper once a week for two weeks in a row, and she needs clearances such as from the NBI and PNP, so it takes longer.
Where. Kristine now lives in Quezon City. She could file at the Lucena City civil registry, where the birth was recorded, or file a migrant petition (filing where you live now) at the Quezon City civil registry, which PSA lists with an added fee. She goes home to Lucena to file both.
In the meantime. Her recruitment agency asks how long it will take. The registrar explains the steps: posting, publication, the registrar's decision, then review by the PSA. Only after that does the PSA issue a copy with the correction noted on it. Some offices accept an Affidavit of Discrepancy for a while, but it does not fix the PSA record. She should not wait to file.
What the Civil Registrar Can Fix
RA 9048, as amended by RA 10172, lets the city or municipal civil registrar, or a Philippine consul abroad, fix these without a court case:
| Mistake | Example | Law |
|---|---|---|
| Clerical or typographical error (an obvious mistake in writing, copying or typing) | "Ma. Cristina" typed as "Ma. Christina"; a misspelled middle name or place of birth | RA 9048 |
| Change of first name or nickname | Changing "Bebot" to the name you have always used | RA 9048 |
| Day or month of birth | "5 March" instead of "3 May" | RA 10172 |
| Sex | "Male" for a girl, when other early records show it was a typing mistake | RA 10172 |
A first name can be changed only for reasons the law lists: the name is ridiculous, shameful, or very hard to write or say; you have long used another first name and are known by it; or the change will avoid confusion. Wanting a nicer name is not enough. See changing your name.
What Needs a Court Case
These need a petition in the Regional Trial Court under Rule 108 of the Rules of Court (a court case to cancel or correct a civil registry entry), or Rule 103 for a change of surname:
- the year of birth, because it changes your age;
- a surname change that is not a simple misspelling;
- nationality or citizenship;
- whether you are legitimate (born to married parents), or who your parents are;
- a sex entry that was not plainly a typing mistake.
A court case needs a lawyer. The Public Attorney's Office (PAO) helps people who qualify.
How It Goes, and What It Costs
In short: you file a sworn petition (a written request signed under oath) at the civil registry where your birth was recorded, at the one where you live now (a migrant petition), or at the nearest Philippine consulate if you are abroad. Bring at least two documents that show the correct entry, such as a Baptismal Certificate, school records, voter's record, or SSS or employment records. For a birthday or sex correction, your earliest records, like your first school record, matter most.
The petition is posted for 10 days in a row. A change of first name, and a birthday or sex correction, are also published in a newspaper once a week for two weeks in a row. The registrar decides and sends the decision to the PSA, which may object. Once final, your record is annotated (a note showing the correction is added). Then request a new PSA copy.
PSA lists these fees. Very poor (indigent) petitioners do not pay the filing fee.
| Petition | Local Civil Registry | Philippine Consulate |
|---|---|---|
| Clerical error | ₱1,000 | US$50 |
| Change of first name, or day or month of birth, or sex | ₱3,000 | US$150 |
A migrant petition costs extra. Newspaper publication, clearances, certified copies and notarization are separate.

Common Questions
Iba ang Birthday Ko sa PSA at sa School Records Ko. Alin ang Susundin?
Your PSA Birth Certificate is the official record, and other offices will usually follow it. If the PSA entry is the wrong one, have it corrected. If the PSA entry is right and only your other records are wrong, ask the school or office that issued them to fix theirs.
Is an Affidavit of Discrepancy Enough?
It explains that two documents refer to the same person, and some offices accept it. It does not change your PSA record. For a passport, a visa or work abroad, you will usually need the record itself corrected. Use the Affidavit of Discrepancy template only as a stopgap (a temporary fix).
Mali ang Taon ng Kapanganakan Ko. Kaya ba sa Munisipyo?
No. RA 10172 covers only the day and month. The year changes your age, so it needs a court petition under Rule 108.
Can My Mother File for Me While I Am Working Abroad?
PSA allows a parent, spouse, child, brother or sister, grandparent or guardian to file, or anyone you authorize with a Special Power of Attorney. You can also file at the nearest Philippine consulate yourself. Ask the civil registry first whether your personal appearance is needed for the kind of petition you are filing.
My Middle Name Is Missing on My Birth Certificate. Is That a Clerical Error?
It depends on why it is missing. If it was simply left out by mistake and your parents' names are correctly recorded, the civil registrar may treat it as clerical. If adding it would change whether you are legitimate or who your parents are, it needs a court case. Ask the civil registry how they will treat it.
