In short
- What it is
- A sworn statement that two or more documents with different entries refer to one and the same person — you.
- Notarised?
- Yes.
- Typical cost
- About ₱100–₱300 for notarisation.
- Important limit
- It explains a mismatch. It does not correct your birth certificate — that needs RA 9048 / RA 10172 at the local civil registrar.

6. [ANNA MARIE RIVERA REYES], [ANA MARIE R. REYES] and the person named in the said Transcript of Records refer to one and the same person, that is, myself;

Series of 20____.The problem this document solves
Filipino records disagree with each other constantly. A middle initial appears in one document and not another, a school spells a surname the way it sounds, a clerk types 1993 for 1994, a married woman appears under her maiden name in one file and her married name in another. When an agency notices, the transaction stops — and what they usually ask for is an affidavit of discrepancy.
Its whole job is to declare, under oath, that the differing entries belong to one person, to identify which entry is correct, and to explain how the difference arose. It is accepted by the DFA for passports, by the SSS, GSIS, Pag-IBIG and PhilHealth, by banks, by schools, and by employers.
Which entry should you declare as the correct one?
As a rule, the PSA civil registry record controls. Your Certificate of Live Birth is the primary evidence of your name and date of birth, and agencies treat everything else as secondary. So unless the birth certificate itself is the document in error, declare the birth certificate entry as the true and correct one, and describe the others as errors in transcription.
If the birth certificate is the wrong one — you were actually born on a different date, or your name was misspelled at registration — say so plainly and file the RA 9048 or RA 10172 petition. In that case the affidavit of discrepancy is a stopgap while the correction is processed, and you should say which petition is pending.
Common discrepancies and how agencies treat them
| Discrepancy | Usually accepted with an affidavit? | Notes |
|---|---|---|
| Missing or extra middle initial | Yes | The most routine kind; one affidavit usually clears it |
| Spelling variant of a first name or surname | Yes | Attach both documents so the office can see the pair |
| Married vs maiden surname | Often not needed | A PSA marriage certificate usually explains it by itself |
| Different day or month of birth | Sometimes | For a passport or an SSS claim, expect to be told to correct the record under RA 10172 |
| Different year of birth | Rarely | Treated as substantial; usually needs a court petition |
| Different place of birth | Sometimes | Depends on the agency and whether the birth certificate is consistent |
| Two different persons' records mixed up | No | This is not a discrepancy — it needs correction at the registry, not an affidavit |
Legal basis: RA 9048 as amended by RA 10172 (administrative correction of clerical errors and of the day and month of birth and sex); Rule 108 of the Rules of Court (judicial correction of substantial entries); Revised Penal Code art. 183 (perjury).
How to fill it in
- 1
List every document that disagrees
Give the document's full name, its issuing office, and its number. One numbered paragraph per document. Do not summarise — quote the entry exactly as it appears, in quotation marks.
- 2
Explain the cause honestly
'A typographical error committed at the time of encoding' is the usual and truthful cause. If you actually used a different name for years, say that instead — do not misstate it under oath.
- 3
Declare the correct entry
State plainly which entry is true and correct, and name the document it comes from.
- 4
Add the one-and-the-same-person clause
This is the sentence the agency is looking for: that all the names listed refer to one and the same person, yourself.
- 5
State the purpose
Name the office and the transaction. Agencies file the affidavit against that transaction.
If the record itself has to be corrected: the RA 9048 route
When the affidavit is only a stopgap and the PSA record must actually change, the process is administrative and you file it at the local civil registrar — not in court, and not through the PSA directly.
- 1
File the petition where the record is kept
At the local civil registry office of the city or municipality where the birth was registered. If you now live elsewhere, you may file a petition in your place of residence for transmittal, and Filipinos abroad may file through the Philippine Consulate.
- 2
Bring the supporting documents
The PSA copy of the record to be corrected, and at least two public or private documents showing the correct entry — baptismal certificate, school records, voter's records, employment records, medical records, an NBI or police clearance. The registrar decides how many are enough.
- 3
Pay the filing fee and, for a change of first name, publish
A petition to change a first name or nickname must be published once a week for two consecutive weeks in a newspaper of general circulation. A simple clerical correction does not require publication.
- 4
Wait for the decision and the annotated record
The registrar decides, and the decision is transmitted to the Civil Registrar General for affirmation. What you eventually receive is an annotated PSA copy — the original entry stays visible with the correction noted beside it.
RA 10172 extended this administrative route to corrections in the day and month of birth and in the entry for sex, where the error is clerical or typographical — but those petitions require publication and stricter proof, including earliest school and medical records and, for a correction of sex, a certification from an accredited physician that the petitioner has not undergone a sex change or transplant. Anything beyond that — the year of birth, legitimacy, filiation, nationality — still needs a court petition under Rule 108.
What if…
- 1
…the agency also wants an affidavit of two disinterested persons
That is common where the discrepancy is old or the supporting records are thin. Two people not related to you swear that they have known you for years and that you are the same person in both records.
- 2
…the discrepancy is in a deceased relative's records
You can execute the affidavit as an heir, describing your relationship and personal knowledge. For estate and BIR purposes, expect to also produce the PSA documents connecting the names.
- 3
…you have been using the wrong name for decades
Consider a proper change-of-name petition under RA 9048 rather than repeatedly explaining the difference. Agencies increasingly refuse to accept serial affidavits in place of a corrected record.
Frequently asked questions
+Can an affidavit of discrepancy correct my birth certificate?
No. It only explains that two records refer to the same person. To change the PSA record itself you file a petition with the local civil registrar under RA 9048 (clerical errors, change of first name) or RA 10172 (day and month of birth, sex), or a court petition under Rule 108 for substantial changes.
+Is an affidavit of discrepancy the same as an affidavit of one and the same person?
In practice they are used interchangeably, and offices accept either title. The 'one and the same person' clause is simply the operative paragraph of a discrepancy affidavit, so this document covers both.
+Will the DFA accept an affidavit of discrepancy for my passport?
For minor name variations, often yes, together with your PSA birth certificate and supporting IDs. For a mismatch in your date of birth, expect to be required to correct the civil registry record first under RA 10172.
+Do both my old and new documents need to be attached?
Yes. Bring photocopies of every document you referred to in the affidavit, plus the originals for verification. An affidavit describing documents the office cannot see is of little use to them.
