Quick answer

An affidavit is a written statement of facts made under oath or affirmation. In the Philippines, it ordinarily requires a jurat: the affiant must appear before an authorized notary public, prove their identity, sign the complete affidavit in the notary’s presence, and swear or affirm that its contents are true.

Notarization verifies the oath, identity, signature, personal appearance, and voluntariness required for the notarial act. It does not automatically prove that every statement is true, cure false or unlawful content, establish ownership, or guarantee that a court or government agency will accept the document. The affidavit must still satisfy the particular law, rule, form, supporting-document requirement, and filing deadline governing its intended use.

What a valid affidavit should contain

Requirements vary by purpose, but a properly prepared affidavit generally includes:

The affiant’s complete name, age or legal capacity when relevant, citizenship when material, civil status when required, and address;
A clear statement that the affiant is competent to testify and is stating facts from personal knowledge, authentic records, or another specifically identified basis;
Numbered paragraphs describing the relevant facts in chronological, precise language;
The identities of other persons involved, using exact names found in official records;
Dates, places, amounts, document numbers, and other details that are material and can be verified;
A description of every supporting document, with annex markings when attachments are used;
The purpose for which the affidavit is being executed;
The affiant’s signature; and
An appropriate jurat completed, signed, and sealed by the notary.

Use the form required by the receiving court, prosecutor, registry, bank, employer, school, or government agency. An “affidavit of loss,” “complaint-affidavit,” “affidavit of support,” “joint affidavit of two disinterested persons,” and “judicial affidavit,” for example, serve different purposes and may have different substantive and procedural requirements.

Jurat versus acknowledgment

These notarial acts are not interchangeable.

Jurat

A jurat is normally used for an affidavit. The affiant:

Appears before the notary;
Presents the affidavit;
Signs it in the notary’s presence; and
Takes an oath or affirmation that its contents are true.

The notary then completes a certificate commonly beginning with “Subscribed and sworn to before me.”

Acknowledgment

An acknowledgment is usually used for contracts, deeds, powers of attorney, and similar instruments. The signer appears before the notary and declares that the signature was voluntarily affixed and that the instrument is the signer’s free and voluntary act and deed. A document may already have been signed before an acknowledgment, although the signer must personally appear and acknowledge the signature.

Putting an acknowledgment on a document that is supposed to be sworn does not necessarily create a valid affidavit. The definitions and requirements appear in the Supreme Court’s 2004 Rules on Notarial Practice.

Personal appearance is the general rule

For traditional paper notarization, the affiant must personally appear before the notary at the time of the notarial act. Sending a signed affidavit through a relative, messenger, law-office employee, or courier is not enough. Neither is appearing through an ordinary video call and later emailing a scanned signature.

Personal acquaintance with the notary does not eliminate the appearance requirement. It may affect how identity is established, but the affiant must still appear for the jurat.

The notary must also act within the territorial jurisdiction covered by the notarial commission. A lawyer is not automatically authorized to notarize merely because they are a member of the Bar; the lawyer must hold a current notarial commission for the relevant city or province.

The Supreme Court repeatedly enforces these safeguards because notarization gives a document public character and evidentiary advantages. See, for example, Dandoy v. Edayan and Balaoing v. Laya.

Identification requirements

Unless the affiant is personally known to the notary, identity must be established through competent evidence of identity. The usual requirement is at least one current identification document issued by an official agency bearing the affiant’s photograph and signature.

Examples recognized under the amended rules include passports, driver’s licences, PRC IDs, SSS or GSIS cards, and other qualifying government-issued identification. The notary may require additional proof when names, photographs, signatures, addresses, or other details do not reasonably match.

A community tax certificate or cedula alone is not competent evidence of identity because it does not satisfy the photograph-and-signature requirement. The Supreme Court confirmed this in Dandoy v. Edayan.

The rules also allow identification through qualified credible witnesses, subject to strict conditions. The witnesses must personally know the affiant, must not be parties or otherwise privy to the document or transaction, and must satisfy the applicable identification requirements. This is not a casual substitute for bringing valid identification.

If the affidavit uses a married name, former name, nickname, spelling variation, or inconsistent middle name, bring the civil-registry records or other official documents that explain the difference. Do not alter a name merely to make it match one document.

Do not sign an incomplete affidavit

A notary may not notarize a blank or incomplete document or attach a signature and seal to an incomplete notarial certificate. Before signing, check that:

All pages are present and in the correct order;
Names, dates, addresses, amounts, and reference numbers are complete;
Unused material spaces are closed or properly marked;
Corrections are clear and properly initialled where appropriate;
Every annex referred to in the affidavit is attached and correctly labelled;
Page counts are accurate; and
The jurat is suitable for an affidavit.

Never sign loose signature pages intended to be attached later. Do not allow anyone to replace pages, insert facts, change amounts, or add annexes after notarization. If a material correction is needed, the safest course is usually to prepare and notarize a corrected affidavit.

What the notary must check—and what notarization does not prove

The notary must be satisfied as to identity, personal appearance, the required oath or affirmation, voluntariness, and the completeness of the instrument. A notary should refuse when the signer appears not to understand the transaction, is acting under coercion, or cannot communicate sufficiently for a proper notarial act.

The notary is disqualified if the notary is a party to the document, will receive a prohibited direct or indirect benefit, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by blood or marriage within the fourth civil degree.

However, notarization is not a judicial finding that the affidavit’s allegations are correct. It does not:

Transfer property or establish ownership by itself;
Replace civil-registry, land-registration, corporate, or accounting records;
Make hearsay or speculation admissible;
Cure a document prohibited by law;
Bind a person who did not execute it;
Prevent the affiant from being questioned or cross-examined; or
guarantee acceptance by the intended recipient.

A defective notarization generally strips the document of its public character and reduces it to a private document requiring proper authentication. Whether the underlying act remains valid depends on the governing law and the nature of the transaction. The Supreme Court explains this consequence in Heirs of Amado Celestial v. Heirs of Editha Celestial.

Paper and electronic notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, effective in 2025, supplement rather than replace traditional notarization.

They recognize:

In-person electronic notarization (IEN): the principal physically appears before an electronically commissioned notary and executes an electronic document through an accredited electronic notarization facility; and
Remote electronic notarization (REN): the principal appears virtually through the accredited facility’s synchronous videoconferencing and identity-verification process.

For an electronic jurat, the principal must affix the electronic signature through the facility in the electronic notary’s full view and take the required oath. The electronic notary completes the electronic notarial certificate and applies the authorized electronic signature and electronic notarial seal.

A generic video call, scanned handwritten signature, emailed PDF, commercial e-signing service, or foreign online-notary website does not by itself comply. Use only a duly commissioned Electronic Notary Public and a Supreme Court-accredited Electronic Notarization Facility, and confirm current availability through the Court’s eNotary Services page and official FAQs.

For a principal outside the Philippines, Philippine electronic notarization is narrowly limited: during the notarial act, the principal must be within the premises of a Philippine embassy, consular office, or office of a Philippine honorary consul, with the location confirmed as the rules require.

Affidavits signed abroad

A person abroad generally has two practical routes for an affidavit intended for use in the Philippines:

Personally appear and sign before an authorized officer at the appropriate Philippine embassy or consulate; or
Sign before a local notary and obtain an apostille from the foreign country’s competent authority if both countries are covered by the Apostille Convention.

For a country or document not covered by the Convention, further authentication or legalization may be required. The requirements of the particular Philippine agency or proceeding must also be checked. Philippine posts explain these alternatives in their official guidance, such as the Philippine Embassy in Washington’s consular-notarization guidance.

An apostille authenticates the origin of the foreign public or notarial document; it does not certify that the affidavit’s factual statements are true. The Supreme Court discusses apostilled notarial acts in Republic v. Ng.

Fees, receipts, and electronic copies

There is no safe assumption that every affidavit has a single nationwide commercial price. The applicable notarial fee, any separately agreed travel expense, the number of originals, and separate legal fees for drafting or advice can affect the amount charged.

Before proceeding:

Ask for the posted schedule of notarial fees;
Clarify whether drafting or consultation is a separate service;
Agree in advance to any permitted travel expense; and
Obtain a BIR-registered receipt.

Under the 2025 amendments to the notarial rules, a notary may not charge separately for digitizing, transmitting, storing, disposing of, or otherwise processing the digital copy required by the rules.

Upon mutual agreement, the notary must send each signatory an electronic duplicate at no additional cost within five days from completion of the notarial act or, where applicable, from the deadline for transmitting the duplicate original to the clerk of court. A signatory may waive electronic transmittal, but the rules attach consequences to that waiver. If the electronic copy contains a material discrepancy, notify the notary promptly in writing and request correction.

Practical checklist

Before the appointment

Ask the intended recipient for its current form, documentary requirements, number of originals, and deadline.
Prepare a factually complete draft. Use only facts you can honestly swear to.
Gather supporting records and mark annexes consistently.
Bring the complete, preferably unsigned affidavit.
Bring a current government-issued ID bearing your photograph and signature.
Bring explanatory records for any name or signature discrepancy.
Confirm that the notary has a current commission and may act in that territory.
Arrange for qualified witnesses if the particular affidavit or identification method requires them.

During notarization

Read every page, including the jurat.
Correct errors before signing.
Sign only when instructed and while personally before the notary.
Take the oath or affirmation seriously.
Ensure the notary records the act and completes the certificate, signature, seal, commission details, and notarial references.
Ask for a receipt and agree on delivery of the electronic duplicate.

After notarization

Check that the notarial certificate is complete and legible.
Keep the original securely and make a clear scan of every page and annex.
Preserve the receipt, transmission email, electronic duplicate, filing acknowledgment, and any agency instructions relied upon.
Compare the electronic duplicate with your paper copy immediately.
Submit the affidavit through the correct channel before the applicable deadline.

Common mistakes

Using an acknowledgment instead of a jurat;
Signing outside the notary’s presence;
Accepting “notarization” through an ordinary video call;
Relying on a cedula alone as identification;
Using an expired or unreadable ID;
Leaving blanks for names, dates, amounts, or property descriptions;
Attaching different annexes after notarization;
Stating rumours, assumptions, or legal conclusions as personal knowledge;
Copying an internet template without checking the receiving agency’s form;
Treating notarization as proof of title, identity, filiation, loss, or payment;
Allowing a notary’s employee to sign, seal, or complete the certificate;
Using a notary outside the territorial jurisdiction of the commission; and
Ignoring discrepancies between the paper original and the electronic duplicate.

False affidavits and other legal exposure

Do not swear to a fact you know is false, hide a material qualification, or sign an affidavit whose language you do not understand.

Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making an untruthful statement under oath on a material matter before an authorized officer, when required by law or made for a legal purpose, may constitute perjury. The ordinary statutory penalty is prisión mayor in its minimum period—six years and one day to eight years. Special consequences apply when the offender is a public officer or employee, including the statute’s higher-period, fine, and disqualification provisions.

An incorrect statement is not automatically perjury. The prosecution must establish the statutory elements, including a willful and deliberate assertion of falsehood concerning a material matter. The Supreme Court explains those elements in Saulo v. Department of Agriculture. Depending on the conduct and document, falsification, fraud, contempt, administrative sanctions, civil liability, or case-specific penalties may also be relevant.

When legal help is urgent

Consult a Philippine lawyer promptly when:

The affidavit concerns land, inheritance, corporate authority, a large financial obligation, immigration status, custody, domestic violence, or possible criminal conduct;
You are being asked to admit liability, waive rights, withdraw a complaint, or contradict an earlier sworn statement;
A filing, appeal, prescription, protest, or regulatory deadline is near;
Someone signed or notarized the affidavit without your personal appearance;
Pages, annexes, dates, amounts, or signatures appear to have been changed;
The notary’s commission, seal, territorial authority, or register entry is doubtful;
The affidavit must be used abroad or was executed abroad;
A recipient has rejected the document; or
You discover a material error after filing.

Preserve the disputed original, envelope, receipt, emails, messages, electronic files and metadata, filing acknowledgments, and any proof of where the affiant was on the stated notarization date. Do not write on, detach pages from, or “repair” the questioned document.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is, by nature, a sworn statement and ordinarily requires an oath or affirmation before an authorized officer. Some procedures accept a different form of verified declaration or prescribe their own oath-taking method, so follow the specific governing rule or official form.

Can I sign the affidavit before meeting the notary?

For a jurat, sign in the notary’s presence. If you signed prematurely, disclose this and follow the notary’s lawful instructions; do not conceal when or where the signature was made.

Is one valid ID always enough?

One current official ID bearing a photograph and signature can satisfy the general documentary standard, but the notary or receiving agency may reasonably require additional proof, especially where details conflict or a special rule applies.

Can a notary prepare the affidavit for me?

A lawyer may draft an affidavit or give legal advice, but drafting and notarization are distinct services. The facts must come from the affiant, who remains responsible for their truth and completeness. A notary should remain impartial in performing the notarial act.

Does an affidavit expire?

There is no universal expiration period for all affidavits. Its usefulness may depend on how current the facts are, a statute or agency rule, the recipient’s stated validity period, or a filing deadline. Confirm the requirement with the intended recipient.

Can a notarized affidavit replace an original certificate or record?

Usually not. An affidavit may explain loss, discrepancy, or circumstances, but an agency can still require the original, certified copy, replacement record, or other primary evidence.

Is a photocopy of a notarized affidavit automatically valid?

No. A recipient may require the original, a certified copy, or an electronically notarized original. A plain photocopy does not automatically carry the same evidentiary or administrative treatment.

Can I correct a notarized affidavit by handwriting over the error?

Do not make unilateral material changes after notarization. Ask the recipient and a lawyer whether a corrected affidavit, supplemental affidavit, or formal re-execution is appropriate.
