Quick answer

An affidavit is a written statement of facts made under oath or affirmation. In the Philippines, it is ordinarily completed through a jurat: the affiant personally appears before a duly commissioned notary public or another officer authorized to administer oaths, proves identity, signs the affidavit in that officer’s presence, and swears or affirms that its contents are true.

Do not merely sign an affidavit and ask someone else to have it notarized. Do not use a community tax certificate or cedula as your only proof of identity. Bring the complete, unsigned document and at least one current government-issued identification document bearing your photograph and signature. The office receiving the affidavit may impose additional wording, attachments, filing methods, or deadlines.

Electronic notarization is legally available under the Supreme Court’s Rules on Electronic Notarization, but it must be performed by an authorized Electronic Notary Public using the prescribed system and procedures. Sending a scanned signature or joining an ordinary video call does not, by itself, make an affidavit validly notarized.

What an affidavit does—and does not do

An affidavit records facts that the affiant declares to be true under oath. It is commonly required for complaints, loss of documents, discrepancies in records, claims, applications, business transactions, and court or administrative proceedings.

Notarization serves important purposes:

It identifies the person who made the statement.
It records that the person personally appeared and took an oath or affirmation.
It helps deter forgery and false statements.
When regularly performed, it generally converts the document from a private document into a public document for evidentiary purposes.

Notarization does not automatically prove that every statement in the affidavit is true. It does not cure false, vague, hearsay, unauthorized, or legally insufficient contents. A court or agency may still require testimony, original records, corroborating evidence, or compliance with a special form.

A defective notarization can strip a document of its public character and reduce it to a private document. In some transactions for which a public document is required for validity—not merely for convenience or proof—the consequences may be more serious. The Supreme Court discusses these distinctions in Patenia-Kinatac-an v. Patenia-Decena.

The basic requirements for a paper affidavit

A complete affidavit

Before notarization, the document should ordinarily contain:

The affiant’s complete name and relevant personal details
A clear title describing the affidavit’s purpose
Facts stated accurately, preferably in numbered paragraphs
Statements based on the affiant’s personal knowledge, with sources identified when appropriate
A clear explanation of why the affidavit is being executed
Properly identified attachments or annexes, if any
A signature block for the affiant
A jurat for completion by the notary or administering officer

Use the exact form required by the receiving court, agency, bank, school, insurer, employer, or other institution. An affidavit of loss, complaint-affidavit, judicial affidavit, affidavit of support, and affidavit of discrepancy serve different purposes and are not interchangeable.

Leave no unexplained blanks. Material alterations should be made before notarization and properly acknowledged. Never ask a notary to seal an incomplete document.

Personal appearance

For conventional paper notarization, the affiant must personally appear before the notary. The notary cannot validly notarize an affidavit through a messenger, relative, fixer, secretary, or delivery service.

For a jurat, the affiant must:

Present the affidavit to the notary.
Be personally known to the notary or properly identified.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation as to its contents.

These requirements come from the 2004 Rules on Notarial Practice, as amended. The Supreme Court has repeatedly treated notarization without the affiant’s appearance as a serious violation; see, for example, Rigon v. Subia.

Competent evidence of identity

If the affiant is not personally known to the notary, the usual requirement is at least one current identification document issued by an official agency and bearing the affiant’s photograph and signature.

Examples recognized under the amended rule include passports, driver’s licenses, PRC IDs, SSS cards, GSIS e-cards, and other qualifying government-issued identification documents. The official list appears in the Supreme Court’s 2008 amendment to Section 12 of the Notarial Rules.

Practical precautions include:

Bring the original ID, not only a photograph or photocopy.
Check that it is current and readable.
Make sure the name on the ID matches the affidavit.
Bring supporting civil-registry or government records if there is a name discrepancy.
Ask the intended notary in advance if the ID lacks a visible signature or has unusual details.

A cedula or community tax certificate is not sufficient by itself under the present competent-evidence requirement. If the affiant has no qualifying ID, the Rules provide a credible-witness method subject to strict conditions. This is not simply permission to bring any friend: the number of witnesses, their relationship to the transaction, their personal knowledge, their identity documents, and whether they are personally known to the notary all matter. Arrange this with the notary beforehand.

Signature in the notarial register

For a conventional notarization, each principal must sign or place the required thumbmark or other mark in the notary’s notarial register at the time of notarization. Credible witnesses and certain signature witnesses must also sign where applicable.

The completed notarial certificate should contain the proper details, including the place and date of notarization and the notarial register references. The notary’s commission and identifying information should appear as required by the Rules.

Jurat versus acknowledgment

An affidavit ordinarily requires a jurat, not a mere acknowledgment.

Jurat	Acknowledgment
Used for a sworn or affirmed statement	Used when a person acknowledges executing an instrument as a voluntary act
Affiant signs in the notary’s presence	The document may already have been signed, provided the signer personally appears and acknowledges it
Affiant swears or affirms that the contents are true	Signer acknowledges that the instrument is the signer’s free and voluntary act
Common for affidavits, verifications, and sworn statements	Common for deeds, contracts, powers of attorney, and similar instruments

Using the wrong certificate can create evidentiary or validity problems. A deed requiring acknowledgment should not be treated as an affidavit merely by attaching a jurat, and an affidavit should not be notarized without administering an oath or affirmation.

Electronic notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, took effect in 2025. They govern electronic notarial acts performed by an authorized Electronic Notary Public, or ENP.

Electronic notarization is not the same as:

Emailing a signed PDF to an ordinary notary
Pasting an image of a signature or seal onto a document
Appearing through an informal video call without the required platform and safeguards
Scanning a conventionally notarized paper and calling the scan electronically notarized

The electronic document, identity verification, electronic appearance, signature, electronic notarial certificate, records, and system used must comply with the Rules. An ENP may perform only authorized electronic notarial acts and must observe the applicable jurisdictional and technical requirements.

Paper documents with wet signatures remain governed by the conventional Notarial Rules. Before choosing electronic notarization, confirm both that an authorized ENP can perform it and that the receiving institution accepts the resulting electronic document. The Supreme Court provides an official electronic-notarization FAQ.

Affidavits signed outside the Philippines

If an affidavit will be executed abroad, first ask the Philippine office that will receive it what form of authentication it requires.

Depending on the country and intended use, the affidavit may be:

Sworn before an authorized official at a Philippine embassy or consulate;
Notarized under the law of the country where it is signed and then apostilled, if the relevant countries and document fall under the Apostille Convention; or
Subject to another authentication or legalization process when the apostille procedure does not apply.

Local notarization abroad and authentication for use in the Philippines are separate questions. An apostille generally authenticates the origin of the public document—such as the signature or official capacity of the person who executed or certified it—not the truth of the affidavit’s factual contents.

Electronic notarization may offer another route in circumstances allowed by the Supreme Court’s rules, including specific provisions concerning principals outside the Philippines. Confirm eligibility with an authorized ENP and with the receiving office before proceeding.

Special rules may change the requirements

Judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it generally takes the place of a witness’s direct testimony in proceedings covered by the Rule.

Among other requirements, it must contain consecutively numbered questions and answers, the witness’s identifying details, information concerning the examining lawyer and examination, the required warning about criminal liability, identification of evidence, the witness’s signature, a jurat, and the lawyer’s sworn attestation.

As a general rule, covered parties must file and serve judicial affidavits and attached exhibits not later than five days before the applicable pre-trial, preliminary conference, or scheduled hearing. Late submission is ordinarily deemed waived. A court may allow late submission only once under the conditions in Section 10, including a valid reason, absence of undue prejudice, and payment of the prescribed fine.

Always follow the current court order and procedural rule applicable to the particular case. Do not convert a lawyer-prepared judicial affidavit into a generic affidavit or alter its questions, answers, exhibits, or attestation without legal advice.

Complaints and agency submissions

Prosecutors’ offices, the police, courts, local civil registrars, the Bureau of Immigration, the Department of Foreign Affairs, insurers, banks, and other bodies may each prescribe their own forms and attachments. Some accept affidavits only within a specific filing period or as part of a larger complaint or application.

There is no single universal deadline for every affidavit. The controlling period comes from the law, procedural rule, agency issuance, contract, court order, or notice governing the particular matter. Notarizing an affidavit does not stop prescription, perfect an appeal, or complete a filing unless the applicable rule says so.

Practical steps before notarization

Ask the receiving office for its latest checklist. Confirm the form, required wording, number of originals, attachments, acceptable language, filing channel, and deadline.
Write only facts you can honestly support. Separate what you personally saw or did from information learned from another person.
Check every name, date, amount, address, and document number. Compare them with official records.
Label attachments clearly. Bring originals or certified copies when required. Do not describe an attachment that is missing.
Keep the affidavit unsigned until instructed by the notary. This is especially important because a jurat requires signing in the notary’s presence.
Bring valid identification. If there is an identity or name problem, discuss it with the notary before the appointment.
Appear personally and take the oath or affirmation. Read the final version before signing.
Review the completed notarization. Check that the jurat is filled in, the notarial details are complete, and all pages and attachments are properly handled.
Keep a complete copy and proof of filing. Notarization and filing are separate acts.

Evidence to preserve

Keep secure copies of:

The final notarized affidavit, including every page and annex
The documents supporting each important factual statement
The form or instructions supplied by the receiving office
Filing receipts, docket numbers, acknowledgment emails, and courier records
Relevant messages, photographs, recordings, contracts, official records, and transaction receipts
The name and office details of the notary
Any electronic-notarization confirmation, audit record, or validation information provided through the authorized process

Preserve originals where authenticity may later be disputed. Do not edit a notarized affidavit or replace its pages. If a material correction is needed, ask whether a corrected or supplemental affidavit must be executed.

Common mistakes

Signing outside the notary’s presence and treating the document as a valid jurat
Sending another person to obtain notarization
Using a cedula as the only proof of identity
Signing blank pages or an incomplete form
Leaving the date, venue, annexes, or notarial certificate incomplete
Using an acknowledgment when a jurat is required, or vice versa
Copying a generic online form without checking the receiving office’s requirements
Making legal conclusions instead of stating concrete facts
Including allegations based only on rumor without identifying their source
Altering the document after notarization
Assuming notarization is the same as filing, registration, apostille, or authentication
Assuming every scanned or remotely signed document qualifies for electronic notarization
Missing the underlying complaint, appeal, court, or agency deadline while arranging the affidavit

When legal help is urgent

Consult a Philippine lawyer promptly if:

The affidavit concerns a crime, arrest, subpoena, investigation, or possible self-incrimination.
You are being pressured to sign facts you do not understand or believe are false.
The affidavit involves land, inheritance, marriage, custody, immigration, a large debt, corporate authority, or substantial property.
A filing, appeal, prescription, protest, or response deadline is approaching.
Your signature or notarization appears to have been forged.
The document was notarized without your appearance.
Pages or material terms were added or changed after you signed.
A court or agency has rejected the affidavit.
The affiant cannot read, cannot sign, has impaired capacity, needs an interpreter, or requires accommodation.
The affidavit must be executed abroad or electronically and the receiving office’s requirements are unclear.

A questionable notarization should not be “fixed” by altering the document. Preserve the original and obtain advice about a replacement affidavit, evidentiary objection, complaint, or other appropriate remedy.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is, by nature, a statement made under oath or affirmation. It therefore needs a proper jurat administered by a notary public or another officer legally authorized to administer oaths. A simple signed statement may still have evidentiary value in some settings, but it is not a duly sworn affidavit merely because it is titled “Affidavit.”

Can I sign the affidavit before meeting the notary?

For a jurat, the affiant must sign in the notary’s presence. Bring the document unsigned unless the authorized administering officer gives instructions consistent with the applicable electronic-notarization process.

Is one valid government ID enough?

The Rules generally refer to at least one current official identification document bearing the person’s photograph and signature. A particular institution or notary may reasonably request additional proof where identity, validity, matching names, authority, or document integrity remains uncertain.

Is a barangay clearance or cedula sufficient?

A cedula alone is not competent evidence of identity under the present rule. A barangay document qualifies only if it satisfies the governing definition and current requirements; do not assume that every barangay-issued paper is sufficient. Bring a current photo-and-signature government ID whenever possible.

Does notarization make the affidavit’s contents true?

No. The jurat records the affiant’s appearance, identity, signature, and oath or affirmation. The truth and legal effect of the statements can still be challenged and must be evaluated with the other evidence.

Can a relative have my affidavit notarized for me?

No. The affiant must personally participate in the notarial act. A relative may help arrange the appointment but cannot take the oath or appear in the affiant’s place.

Can any lawyer notarize an affidavit?

No. For conventional notarization, the lawyer must hold a current notarial commission and act within the authority and territorial jurisdiction of that commission. Electronic notarization additionally requires authorization as an ENP.

How long is a notarized affidavit valid?

There is no universal expiration period for all affidavits. Its usefulness depends on the purpose, the age of the facts stated, the receiving institution’s rules, and any governing deadline. Some offices require a recently executed affidavit even though the notarization itself has not “expired.”

Can an affidavit be corrected after notarization?

Do not erase, overwrite, replace pages, or insert new facts after notarization. Material corrections ordinarily require a new, corrected, or supplemental affidavit and a new oath or affirmation.

What happens if an affidavit is false?

A knowingly false sworn statement may expose the affiant to criminal, civil, administrative, procedural, or employment consequences, depending on the facts and the law that applies. The precise offense and penalty cannot be determined merely from the document’s title; intent, materiality, the administering officer’s authority, and the proceeding or purpose all matter.
