Quick answer

An affidavit is a written statement of facts made voluntarily under oath or affirmation. For a standard paper affidavit in the Philippines, the affiant must ordinarily:

Use the form required by the court, agency, employer, bank, school, or transaction, if one is prescribed.
State facts that the affiant personally knows, accurately and completely.
Present the complete, unsigned affidavit to a duly commissioned notary public.
Personally appear before the notary with acceptable proof of identity.
Sign the affidavit in the notary’s presence and take an oath or affirmation that its contents are true.
Ensure that the notary completes the jurat, signs and seals the document, and records the act in the notarial register.

A notary should not notarize a blank or incomplete document, a document signed by an absent person, or one whose signer cannot be properly identified. Sending a signed paper affidavit through a messenger—or asking a notary to “just stamp it”—does not satisfy the ordinary personal-appearance requirement.

Electronic notarization is now recognized under separate Supreme Court rules, but it applies only to qualifying electronic PDF or PDF/A documents processed through an accredited electronic-notarization facility by a commissioned Electronic Notary Public. A scan of a paper document bearing wet signatures does not become eligible merely because it is saved as a PDF.

What an affidavit must contain

There is no universal affidavit form suitable for every purpose. Requirements vary for affidavits of loss, complaints, desistance, support, discrepancy, adverse claim, guardianship, residency, correction, undertaking, and other sworn statements.

A properly prepared affidavit will usually contain:

The correct case caption, transaction title, or document title, when applicable.
The affiant’s full legal name and relevant identifying circumstances.
A statement that the affiant is competent to testify to the matters stated.
Clear, numbered factual paragraphs.
Dates, places, names, document references, and amounts necessary to make the account understandable.
A statement of the purpose for which the affidavit is executed.
References to attachments, with each attachment properly identified.
The affiant’s signature.
A jurat completed by the notary or other officer authorized to administer oaths.

Use the name and spelling appearing in the affiant’s identification documents. If different records contain different names or spellings, explain the discrepancy instead of silently choosing one version.

An affidavit should normally state facts—not guesses, exaggerations, legal conclusions presented as facts, or statements copied from another person. If information came from records or another source, say so and identify the source where relevant.

Jurat versus acknowledgment

An affidavit ordinarily requires a jurat, not merely an acknowledgment.

In a jurat, the affiant:

Personally appears before the notary;
Is personally known to the notary or properly identified;
Signs the affidavit in the notary’s presence; and
Takes an oath or affirmation regarding the truth of the affidavit.

An acknowledgment is different. The person appears before the notary and declares that they executed the document as their free and voluntary act. An acknowledgment is commonly used for contracts, deeds, and powers of attorney. It does not replace the oath required for an affidavit.

The document’s title is not controlling. A paper labeled “Affidavit” but bearing only an acknowledgment may be defective for the purpose for which a sworn statement is required. Conversely, adding “subscribed and sworn” language cannot cure the absence of the affiant or the failure to administer an oath.

The Supreme Court has explained this distinction in Dela Rama v. Papa.

Personal appearance is mandatory for ordinary paper notarization

Under the 2004 Rules on Notarial Practice, a traditional notary public may not notarize a document if the signatory is not personally present at the time of notarization.

For a paper affidavit, this means:

The affiant must appear before the commissioned notary.
The affidavit must be signed in the notary’s presence for the jurat.
The notary—not a secretary, clerk, messenger, or law-office employee—must perform the notarial act.
A video call, emailed signature page, photograph of an ID, or assurance from another person does not satisfy the traditional rules.
A representative cannot take the affiant’s oath on the affiant’s behalf.

The Supreme Court repeatedly treats personal appearance as a substantive safeguard because it allows the notary to verify identity, observe voluntariness, and administer the oath. See, for example, Sanchez v. Inton.

A traditional notary’s authority is also territorially limited by the commission. Check that the notary is commissioned for the place where the notarial act occurs. The notarial certificate should accurately state that venue.

Acceptable proof of identity

If the affiant is not personally known to the notary, the notary must establish identity through “competent evidence of identity.”

The general documentary route is at least one current identification document that:

Was issued by an official agency; and
Bears both the affiant’s photograph and signature.

Examples recognized in the rules and decisions include a passport, driver’s license, PRC ID, SSS card, GSIS e-card, senior-citizen card, seaman’s book, alien certificate of registration, and qualifying government-office identification. The document must be current and must allow the notary to identify the person appearing.

A Community Tax Certificate or cedula, standing alone, does not meet the current definition because it ordinarily lacks the required photograph and signature. A TIN number alone is likewise insufficient.

Where the prescribed documentary proof is unavailable, the rules provide a credible-witness method:

One credible witness who is not involved in the document or transaction, is personally known to the notary, and personally knows the affiant; or
Two credible witnesses who are not involved in the document or transaction, each personally knows the affiant, and each presents documentary identification to the notary.

This is not an automatic substitute whenever an affiant forgets an ID. The notary must be satisfied that every requirement is met.

Bring the original identification document. A receiving office may separately require photocopies, but a photocopy alone may not allow the notary to verify authenticity. The Supreme Court discusses the current identification standard in Bautista v. Bernabe.

What the notary must check and record

Before completing the act, the notary should determine that:

The person appearing is the affiant.
The affiant understands the nature and consequences of the document.
The signature and oath are voluntary.
The affidavit is complete.
The notarial act is not prohibited.
The notary is not disqualified by a personal interest or prohibited relationship.
The transaction is not plainly unlawful or fraudulent.

For every notarial act, the notary must make the required entry in the notarial register. The entry ordinarily includes the date and time, type of notarial act, description of the document, name and address of the principal, identity evidence used, fee, and other required circumstances. The rules also contain signature or thumbmark and document-copy requirements.

Recent amendments strengthened electronic reporting and document-preservation safeguards for traditional notarial practice. These amendments are available in the Supreme Court’s Amended 2004 Notarial Rules.

Before leaving, inspect the completed jurat. It should not contain blank spaces and should accurately show the place and date of notarization, the affiant’s identity details where required, and the notary’s signature, seal, commission information, and notarial register particulars.

Documents a notary should refuse

A notary should refuse to proceed when, among other grounds:

The affidavit is blank or materially incomplete.
The affiant is absent.
The affiant has not been properly identified.
The affiant refuses or fails to take the oath or affirmation.
The notary has reason to believe the affiant is not acting knowingly or voluntarily.
The affiant appears unable to understand the document.
The transaction is unlawful or the document is false.
The notary is disqualified because of a prohibited interest or relationship.
The requested act is outside the notary’s authority or territorial commission.
The affidavit’s date, stated place, or circumstances would make the notarial certificate untrue.

A legitimate notary may ask questions, request supporting documents, require corrections, or decline the act. Notarization is not a clerical stamping service.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement traditional notarization. They recognize:

In-Person Electronic Notarization: The principal and any witnesses are physically present with the Electronic Notary Public while using the accredited electronic system.
Remote Electronic Notarization: The principal and any witnesses appear virtually through the videoconferencing and identity-verification functions of an accredited electronic-notarization facility.

Electronic notarization is limited to eligible electronic documents in PDF or PDF/A form. It does not apply to:

Paper documents with handwritten signatures or marks;
Notarial wills; or
Depositions.

The process must use a Supreme Court-accredited electronic-notarization facility and a person holding a valid electronic-notarial commission. Identity verification, multi-factor authentication, electronic signatures, the electronic notarial seal, and the electronic notarial book are part of the regulated process.

A scanned wet-signed document is still a paper-origin document for this purpose. It cannot be converted into a valid electronically notarized document merely by uploading the scan.

Electronic notarization and ordinary paper notarization are separate regimes. A lawyer commissioned as a traditional notary is not automatically an Electronic Notary Public. Because implementation and accredited-service availability may change, verify the provider and notary through the Supreme Court’s official electronic-notarization resources before paying or transmitting sensitive records. The Court’s electronic-notarization FAQ explains the distinction.

Even when an affidavit is validly electronically notarized, confirm that the intended court, registry, agency, foreign authority, or private recipient accepts electronic filing or an electronically notarized PDF for that particular transaction.

Does notarization prove that every statement is true?

No. Notarization establishes the performance of the notarial act and gives a regularly notarized document the evidentiary character provided by law. It does not independently investigate or guarantee every factual statement in the affidavit.

Regular notarization can convert a private document into a public document for evidentiary purposes and support a presumption of due execution. That presumption is not absolute. Fraud, forgery, lack of appearance, improper identification, or another serious defect may rebut it.

Defective notarization may strip a document of its public character and reduce it to a private document. Whether the underlying document remains valid depends on the governing law and the nature of the defect. Some transactions require a particular form for validity; others may remain binding but become harder to authenticate. The Supreme Court discusses these consequences in Spouses Patenia v. Spouses Maghuyop.

False statements and perjury

Do not sign an affidavit containing a material statement you know is false.

Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, penalizes knowingly making an untruthful statement under oath or in an affidavit on a material matter before an authorized person when the law requires the oath. The amended law imposes prision mayor in its minimum period. It also provides additional consequences when the offender is a public officer or employee, including a fine of up to ₱1,000,000 and perpetual absolute disqualification from government office.

Perjury is not established by every error or disputed statement. The prosecution must prove the statutory elements, including a willful and deliberate material falsehood. Still, an affiant should correct any material mistake before signing and obtain legal advice immediately if a false affidavit has already been submitted or used.

Filing deadlines and validity periods

There is no single nationwide expiration period for all affidavits. Notarization does not automatically make an affidavit valid forever, nor does an old affidavit automatically become legally void solely because of age.

The controlling deadline or recency requirement may come from:

A statute or court rule;
A court order;
An agency circular, form, or checklist;
A bid, application, or contract;
A bank, school, employer, insurer, or other receiving institution; or
The factual nature of the statement itself.

For example, an affidavit about a person’s present address, support, employment, or financial status may become factually outdated even when no law assigns it a fixed expiration date.

Before notarization, obtain the current form and checklist from the intended recipient. Court submissions may have strict filing periods that notarization does not extend. An affidavit notarized on time but filed late can still be rejected.

Affidavits for court proceedings

Do not assume that a generic notarized narrative will satisfy court rules.

A judicial affidavit used as testimony is governed by the Judicial Affidavit Rule and must follow its prescribed question-and-answer format, lawyer’s attestation, identification of exhibits, and other requirements. Pleadings and supporting affidavits may also be governed by specific civil, criminal, family, small-claims, election, labor, or administrative rules.

If a deadline is running, confirm immediately:

The correct court or office;
The required affidavit format;
Who must execute it;
Whether attachments must be originals, certified copies, or marked exhibits;
Whether service on another party is required; and
The permitted filing channel and deadline.

Notarization alone does not constitute filing.

Affidavits executed abroad

An affidavit intended for use in the Philippines may generally be executed abroad through an authorized Philippine embassy or consulate, subject to that post’s appointment, identity, copy, fee, and appearance requirements.

Another possible route is execution before a competent local notary or authority in the foreign country, followed by:

An apostille, if the issuing and receiving countries are covered by the Apostille Convention; or
The applicable authentication or legalization process if the Convention does not apply.

Requirements vary by country and by the Philippine recipient. Confirm both sides before execution. An apostille authenticates the origin of the public document or notarial certificate; it does not certify the truth of the affidavit’s contents.

For Philippine documents intended for use abroad, consult the DFA’s official Apostille documentary requirements and application process. The destination country or institution may impose additional translation, certification, or form requirements.

Practical checklist before visiting the notary

Ask the receiving office for its latest form and documentary checklist.
Read every paragraph and verify all names, dates, addresses, amounts, and document numbers.
Remove unused alternatives and fill all material blanks.
Mark and arrange every attachment mentioned in the affidavit.
Bring the complete affidavit, but do not sign a paper affidavit requiring a jurat in advance.
Bring at least one current government-issued ID bearing both photograph and signature, preferably with a consistent name and specimen signature.
Bring supporting records that may help the notary understand the document or resolve discrepancies.
Arrange for every affiant and required witness to appear.
Confirm that the lawyer has a valid notarial commission for the place of notarization.
Ask the receiving office whether it needs an original, duplicate originals, certified copies, or an electronic version.
Inspect the completed jurat and notarial details before leaving.
Keep a complete copy and proof of filing or delivery.

Evidence to preserve

Keep:

A complete copy of the affidavit and every attachment.
Copies of the IDs presented, stored securely.
The notary’s name, office address, commission details, and official receipt.
The notarial document, page, book, and series numbers appearing on the certificate.
Appointment confirmations and electronic-notarization audit or verification records, if applicable.
Proof of filing, delivery, or receipt.
The recipient’s checklist or instruction requiring the affidavit.
Drafts and source documents showing how dates, amounts, and other material statements were verified.

If the affidavit concerns a loss, accident, threat, payment, property, online transaction, or disputed event, also preserve contemporaneous messages, photographs, video, receipts, account records, medical records, police or barangay records, and witness contact details.

Common mistakes

Signing a jurat-based paper affidavit before meeting the notary.
Allowing a messenger to bring the signed affidavit for stamping.
Using only a cedula, TIN, or expired identification document.
Leaving material blanks to be filled after notarization.
Using an acknowledgment where a jurat is required.
Stating conclusions without the underlying facts.
Including facts supplied by someone else without identifying the source.
Attaching unread, incomplete, or inconsistent documents.
Using different spellings of a name without explaining the discrepancy.
Assuming notarization automatically makes an unlawful or defective transaction valid.
Assuming an affidavit has no filing deadline.
Treating a scanned wet-signed paper as an eligible electronic document.
Using an unverified online “notary” or non-accredited electronic platform.
Believing an apostille proves the truth of the affidavit.

When legal help is urgent

Consult a Philippine lawyer promptly if:

You are being asked to admit a crime, debt, fraud, negligence, ownership, parentage, or waiver of rights.
The affidavit concerns land, inheritance, corporate authority, immigration, employment dismissal, domestic violence, child custody, or a large financial transaction.
Someone pressures you to sign a blank, backdated, pre-notarized, or inaccurate affidavit.
Your signature or identity was used without permission.
A notarized document states that you appeared when you did not.
You already submitted an affidavit containing a material error or false statement.
A court, prosecutor, police office, regulator, or government agency has set a deadline.
The affidavit will be used abroad or involves foreign law.
The affiant is a minor, cannot read, does not understand the language, has impaired capacity, or is signing through a mark.
The validity of a deed, donation, waiver, settlement, or other transaction depends on a required legal form.

Possible sources of assistance include a private lawyer, the Public Attorney’s Office for qualified clients, an Integrated Bar of the Philippines legal-aid office, or another authorized legal-aid provider. In an emergency involving immediate danger, contact law enforcement or the appropriate protection agency first.

Frequently asked questions

Can I sign the affidavit at home?

For an ordinary paper affidavit with a jurat, the affiant should sign in the notary’s presence. If it was signed earlier, the notary may require a fresh execution rather than simply accepting the existing signature.

Can a relative bring my affidavit to the notary?

Not as a substitute for your personal appearance and oath. A representative may handle delivery or filing only if the receiving office permits it, but cannot appear, sign, or swear for you.

Are two IDs always required?

The Notarial Rules generally define documentary identification as at least one current official-agency ID bearing both photograph and signature. A particular notary, court, agency, embassy, or recipient may reasonably require additional identification or supporting records.

Is a barangay certification enough?

It may qualify only if it satisfies the applicable official-document requirements and allows reliable identification. Because formats vary, bring a stronger government-issued photo-and-signature ID whenever possible.

Can I use a digital signature?

Only through the proper electronic-document and electronic-notarization process, or where another applicable law and the recipient permit it. Pasting an image of a signature into a PDF is not, by itself, valid electronic notarization.

Can an affidavit be notarized remotely?

A qualifying electronic affidavit may be remotely notarized through a Supreme Court-accredited facility by a commissioned Electronic Notary Public under A.M. No. 24-10-14-SC. Ordinary wet-signed paper affidavits remain governed by the traditional rules.

Does a notarized affidavit automatically win a case?

No. The court or agency evaluates admissibility, credibility, relevance, personal knowledge, supporting evidence, and contrary proof. Notarization does not make an implausible or unsupported statement conclusive.

Can a notarization defect be corrected later?

Sometimes a document may be properly re-executed and notarized, but that does not automatically cure a missed deadline, false statement, intervening transaction, or form required for validity. Never alter the notarial certificate yourself. Ask the receiving office or a lawyer what corrective step is legally available.

Does an affidavit automatically expire?

No universal rule makes every affidavit expire after a fixed number of months. The governing law, form, recipient, deadline, and continued truth of the facts determine whether it remains usable.

How much should notarization cost?

The 2004 Rules require the fee to be recorded, but there is no single nationwide price for every private notarial service. Cost may depend on the document, location, professional work involved, and applicable local or institutional rules. Ask for the fee before proceeding and request an official receipt.
