Quick answer

An affidavit is a written statement of facts made under oath or affirmation. For an ordinary paper affidavit in the Philippines, the affiant must personally appear before a duly commissioned notary public or another officer authorized by law to administer oaths, establish identity, confirm understanding and voluntariness, sign in the officer’s presence, and swear or affirm that the statements are true. The notary then completes the jurat.

Not every contract or letter must be notarized. Whether notarization is required depends on the document, the governing law, and the requirements of the court, government agency, bank, school, employer, or other receiving institution. Notarization does not make a false statement true, cure an illegal agreement, transfer ownership by itself, or replace registration and other legal formalities.

Electronic notarization is now recognized under the Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC. It applies to qualifying electronic documents processed by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. Ordinary scanned signatures, video calls, or online “notary” services do not automatically satisfy these Rules.

Affidavit, acknowledgment, and jurat: what is the difference?

These terms are related but not interchangeable.

Affidavit

An affidavit contains factual statements that the affiant declares to be true under oath or affirmation. It normally ends with a jurat.

The affiant should state only facts that the affiant personally knows or can properly identify from records. Conclusions, accusations, estimates, or statements based only on what someone else said should be clearly qualified.

Jurat

A jurat certifies that the affiant:

personally appeared before the notary or authorized officer;
signed the affidavit in that officer’s presence; and
took an oath or affirmation that the contents were true.

The Supreme Court describes a jurat as the part of an affidavit in which the notary certifies that the document was subscribed and sworn to before the notary. See Maloles II v. Phillips.

Acknowledgment

An acknowledgment is generally used for deeds, contracts, powers of attorney, and similar instruments. The signer personally appears before the notary, represents that the signature is genuine and that the document is the signer’s free and voluntary act, and acknowledges executing it.

Unlike a jurat, an acknowledgment may cover a document signed before the appearance, provided the signer personally appears and properly acknowledges the signature and execution. A deed requiring acknowledgment should not be completed with a jurat merely because both are forms of notarization. The Supreme Court has treated using the wrong notarial act as a serious error. See Ladrera v. Osorio.

Requirements for a paper affidavit

For a typical affidavit notarized under the 2004 Rules on Notarial Practice, expect the following requirements.

Personal appearance

The affiant must physically appear before the notary at the time of notarization. Sending a signed document through a relative, messenger, fixer, or office staff member is not enough. A notary must not notarize for an absent signer.

Personal appearance allows the notary to verify identity, willingness, understanding, and the genuineness of the signature. The Supreme Court repeatedly enforces this requirement; see, for example, A.C. No. 9417.

A paper document cannot ordinarily be notarized through an informal video call. Remote electronic notarization follows a separate, technology-based system discussed below.

Competent evidence of identity

If the affiant is not personally known to the notary, the affiant must present competent evidence of identity.

Under the Supreme Court’s 2008 amendment, this generally means at least one current identification document issued by an official agency and bearing the person’s photograph and signature. The official, non-exclusive examples include a passport, driver’s license, PRC ID, GSIS e-card, SSS card, PhilHealth card, senior-citizen card, government-office ID, seaman’s book, and certain government clearances or certifications. See A.M. No. 02-8-13-SC, February 19, 2008.

Important qualifications:

A private company or school ID does not satisfy the rule merely because it has a photograph and signature.
A community tax certificate or cedula alone is not competent evidence of identity under the current rule.
The ID should be current and its name and other details should match the document.
A receiving institution or a cautious notary may reasonably request additional identification or supporting records.
An official card without the required signature may present a problem for traditional paper notarization unless another acceptable method of identification applies.

If no qualifying ID is available, identity may in limited cases be established through credible witnesses meeting the exact conditions in the Notarial Rules. A credible witness must personally know the affiant, must not be a party to or benefit from the document or transaction, and must satisfy the applicable personal-knowledge and identification requirements. This is not a shortcut for using an unqualified ID.

“Personally known” does not mean that the notary met the affiant only during the transaction. It refers to prior personal knowledge of the person’s circumstances independent of representations made during notarization. See Tamayo v. Unite.

Complete and understandable document

The affidavit should be complete before it is notarized. It should ordinarily contain:

the affiant’s full name and relevant personal details;
a clear statement that the affiant is executing the affidavit under oath;
consecutively numbered factual statements;
accurate descriptions of any attached documents;
the purpose of the affidavit, when relevant;
the affiant’s signature over the printed name; and
a proper jurat completed by the notary.

Do not leave material blanks for names, dates, amounts, property descriptions, or other essential terms. Attachments referred to in the affidavit should be present and correctly labeled. Material alterations should be clearly addressed before signing.

The affiant must be able to understand the document. If it is written in a language the affiant does not understand, arrange an accurate translation or interpretation acceptable to the notary and the receiving institution. Never sign a prepared affidavit simply because someone says it is a “standard form.”

Oath or affirmation

The notary must actually administer an oath or affirmation. The affiant must knowingly confirm that the statements are true. Signing a paper in a notarial office without appearing before the notary or without taking an oath is not a proper jurat.

A person may affirm instead of taking a religious oath. Either way, deliberately making a material false statement under oath may expose the affiant to perjury or other liability, depending on the facts.

Signature and notarial certificate

For a jurat, the affiant signs in the notary’s presence. The notary then completes the certificate with the place and date, the affiant’s identity details, the notary’s signature and seal, commission information, and the document, page, book, and series entries required for the notarial register.

The date must be the true date of appearance and notarization. A notary must not backdate or predate the certificate.

Where notarization may be performed

A traditional notary public’s authority is territorial. The notary should act within the territorial jurisdiction covered by the commission and ordinarily at the notary’s regular place of work or business.

The Rules recognize limited situations in which services may be performed elsewhere within the authorized territory, including certain public functions, signings in appropriate public places, a party’s residence, a hospital or medical institution, a place where a party is legally confined, or an emergency. Convenience alone should not be assumed to authorize notarization anywhere in the country.

Before proceeding, check that the lawyer has a current notarial commission for the locality. A lawyer is not automatically authorized to notarize merely because the person is a member of the Philippine Bar.

A notary is also disqualified when the notary has a prohibited personal or financial interest or the specified close family relationship with a principal. Use an independent notary when there is any doubt.

When is notarization legally necessary?

There is no rule that every agreement must be notarized. Contracts are generally binding when the legal requirements for consent, object, and cause are present, subject to statutes requiring a particular form.

Articles 1357 and 1358 of the Civil Code identify transactions that should appear in a public document, including acts involving real rights over immovable property and certain powers affecting such acts. In many situations, the public-document requirement under Article 1358 concerns enforceability, proof, registration, or convenience rather than the intrinsic validity of the agreement. The exact effect depends on the transaction.

Some formalities are indispensable. For example:

A donation of immovable property must be made in a public document, with the property and charges specified; acceptance must also comply with Article 749.
A notarized will must satisfy the acknowledgment and witnessing formalities in the Civil Code. A jurat is not a substitute for the required acknowledgment.
A holographic will has different statutory requirements and does not become valid merely by being notarized.
Marriage settlements must comply with the Family Code’s formal and registration requirements.
Transfers, mortgages, corporate acts, court submissions, immigration papers, and government applications may have separate documentary, tax, registration, authentication, and filing requirements.

Always use the checklist of the particular receiving office. Notarization alone does not replace registration with the Registry of Deeds, payment of taxes, corporate approval, apostille or authentication, witness requirements, or timely filing.

Electronic notarization

The Rules on Electronic Notarization, effective in 2025, supplement rather than replace traditional paper notarization.

They provide two methods:

In-Person Electronic Notarization: the principal and witnesses physically appear before a commissioned Electronic Notary Public while the electronic document and digital-signature process are handled through an accredited facility.
Remote Electronic Notarization: the principal and witnesses appear through a live, synchronous videoconference conducted within the approved electronic facility.

Remote electronic notarization is not simply a meeting through an ordinary video application. Identity verification, digital signatures, document integrity, geolocation, records, and the electronic notarial certificate must be handled through the prescribed system.

As a general rule, participants in remote electronic notarization must be in the Philippines. Limited extraterritorial notarization is allowed when a person abroad is within the premises of a Philippine embassy, consular office, or Philippine honorary consul and the other requirements are satisfied.

Other important limits include:

A traditional paper notarial commission does not automatically authorize electronic notarization.
The electronic document must use the required format and an accredited Electronic Notarization Facility.
Pre-recorded signing videos are not permitted.
Notarial wills and depositions remain governed by their applicable rules.
Availability depends on access to a properly commissioned Electronic Notary Public and an operational accredited facility.

Check the Supreme Court’s electronic-notarization information and FAQs before relying on this option.

Documents signed abroad

A Filipino abroad may generally execute an affidavit, SPA, or other document before the appropriate Philippine embassy or consulate, subject to that post’s appointment, identification, personal-appearance, form, copy, and fee requirements. Requirements vary by post, so consult the official website of the particular embassy or consulate.

Another option may be notarization before a competent foreign notary followed, when required, by an apostille or consular authentication. An apostille does not verify that every statement in the document is true; it authenticates the origin of the relevant public document or certification for international use.

Whether an apostille is required depends on the destination country, the document, and the receiving institution. Use the DFA Authentication Division’s current documentary requirements and official FAQs, rather than assuming that foreign notarization alone is sufficient.

Practical checklist before visiting a notary

Ask the receiving office for its latest form and documentary checklist.
Confirm whether the document needs a jurat, acknowledgment, witnesses, attachments, or another special formality.
Review every statement, name, date, amount, address, and property or case reference.
Bring the complete unsigned affidavit when a jurat is required.
Bring the original of a current government-issued photo-and-signature ID, plus requested copies.
Bring the original or reliable copies of records supporting the affidavit.
Bring all required signers and witnesses; do not ask another person to appear for an absent affiant.
Tell the notary about any language, literacy, vision, hearing, mobility, or signing difficulty before the appointment.
Ensure all material blanks and inconsistent details are resolved before signing.
After notarization, check that the jurat or acknowledgment is complete and keep a clear copy of the entire document and all attachments.
File or submit it before the applicable deadline. Notarization does not extend a court, agency, tax, registration, or contractual deadline.

Evidence to preserve

Keep the following, especially when the affidavit concerns property, money, employment, identity, loss, fraud, family rights, or litigation:

the fully notarized original or a complete high-quality copy;
every page and attachment presented with it;
the ID used and proof that it was valid on the notarization date;
drafts and instructions showing who prepared the document;
receipts and appointment confirmations;
emails, messages, photographs, videos, delivery records, and source documents supporting the statements;
proof of filing, service, or receipt by the intended office; and
the notary’s name, office address, commission details, and notarial register information shown on the certificate.

Preserve originals when authenticity may later be disputed. The Supreme Court has explained that a notarized document generally enjoys a disputable presumption of regular execution, but forgery or irregular execution may still be proved with clear and convincing evidence. See Casimiro Development Corp. v. Mateo.

Common mistakes

Signing an affidavit before meeting the notary.
Allowing a messenger or fixer to obtain notarization for an absent affiant.
Using only a cedula, company ID, or school ID.
Accepting a jurat when the document legally requires acknowledgment, or vice versa.
Notarizing a document with missing pages, unmarked attachments, or material blanks.
Copying allegations the affiant cannot honestly verify.
Using a false address, date, marital status, relationship, or ownership claim.
Assuming notarization proves that all factual statements are true.
Assuming an expired notarized document is automatically invalid—or that an old affidavit will always be accepted. There is no universal expiration period; the receiving office may require a recently executed affidavit because the facts must still be current.
Treating an electronic signature or video call as valid electronic notarization without the prescribed commissioned notary and accredited facility.
Missing a filing or registration deadline while trying to complete notarization.
Relying on notarization to cure an unlawful, forged, simulated, or unauthorized transaction.

When legal help is urgent

Consult a Philippine lawyer promptly if:

you are being pressured to sign facts you do not understand or believe;
the document involves a sale, mortgage, donation, waiver, inheritance, will, marital property, adoption, or transfer of land;
an elderly, ill, detained, visually impaired, illiterate, or otherwise vulnerable person is being asked to sign;
a signature, thumbmark, identity, authority, or notarization is disputed;
a notarized document appears to have been executed without your presence;
material pages or terms were added or changed after signing;
the affidavit will be used in a criminal, administrative, immigration, labor, tax, or election matter;
a court or agency deadline is near;
property has already been transferred or registered using a questioned document; or
you may need an injunction, adverse claim, annotation, preservation order, criminal complaint, or disciplinary complaint.

Do not alter the questioned original. Secure it, preserve comparison signatures and communications, and obtain certified copies from the relevant registry, court, agency, or notarial records office when legally available.

Frequently asked questions

Do I need two valid IDs?

The general Notarial Rules require at least one current official identification document bearing the affiant’s photograph and signature when the affiant is not personally known to the notary. A notary or receiving institution may request more than one ID because of its own verification requirements or concerns about the document.

Can I sign the affidavit at home?

For a paper affidavit with a jurat, the affidavit should be signed in the presence of the notary or authorized officer after identity and understanding are confirmed. If it has already been signed, the notary may require a fresh copy or require the affiant to sign again properly.

Can someone else have my affidavit notarized for me?

No. The affiant’s personal appearance is essential. A representative may sometimes submit or file an already validly notarized document, but cannot take the affiant’s oath or acknowledge the affiant’s signature on the affiant’s behalf.

Does notarization prove that the affidavit is true?

No. Notarization establishes the notarial act and gives the document public-document status and evidentiary consequences, but it does not conclusively prove every factual assertion. The statements may still be challenged, and the affiant may be required to testify.

Is a notarized photocopy the same as a certified true copy?

Not necessarily. A notary cannot automatically convert an ordinary photocopy into an official certified copy of a government or court record. The lawful custodian of the record may need to issue the certified true copy. Ask the receiving office which form it requires.

How long is a notarized affidavit valid?

There is no single expiration period for all affidavits. Its usefulness depends on whether the statements remain true and whether the receiving institution requires a document executed within a particular period. A deadline or freshness requirement must be checked with the court, agency, or institution concerned.

Can an affidavit be in Filipino?

Yes, provided the affiant understands it and the receiving body accepts it. Some proceedings require English or Filipino, or a translation when the witness uses another language. Judicial affidavits have special language, content, lawyer-attestation, exhibit, and filing requirements under the Judicial Affidavit Rule.

Can an affidavit be corrected after notarization?

Do not alter a notarized affidavit unilaterally. A material correction will ordinarily require a corrected or supplemental affidavit, a new personal appearance, a new oath, and a new notarial act. Preserve the earlier version if it was already submitted or may be relevant.

Is notarization free at government offices?

Not necessarily. Some authorized government officers may administer oaths for documents within their official functions, sometimes without a notarial fee, but their authority and procedures are limited. Private notaries may charge professional and notarial fees. Ask for the applicable fee before proceeding and obtain a receipt when appropriate.
