Quick answer

A Philippine affidavit is a written statement of facts that the affiant confirms under oath or affirmation. For a traditional paper affidavit, the affiant generally must:

Use a complete and accurate document with no material blanks.
Personally appear before a duly commissioned notary public.
Establish identity through the notary’s personal knowledge, competent evidence of identity, or the permitted credible-witness procedure.
Sign the affidavit in the notary’s presence.
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 representative ordinarily cannot appear or swear in place of the affiant. A telephone call, ordinary video call, emailed scan, or pasted image of a seal is not a substitute for compliant notarization. Electronic affidavits may now be notarized through a commissioned Electronic Notary Public and a Supreme Court-accredited facility, subject to separate rules.

The governing requirements appear principally in the Supreme Court’s 2004 Rules on Notarial Practice and 2025 Rules on Electronic Notarization.

What notarization does—and does not do

Proper notarization gives a private document the character and evidentiary standing of a public document as to its due execution and authenticity. This is why the Supreme Court treats notarization as a public function, not a routine stamping service.

Notarization does not automatically:

Prove that every factual statement in the affidavit is true.
Make hearsay admissible in court.
Establish ownership, authority, citizenship, employment, relationship, or any other fact that requires independent evidence.
Cure an illegal agreement, an unauthorized signature, a missed filing deadline, or a defective agency or court form.
Turn an affidavit into a deed, contract, special power of attorney, or other instrument that the transaction legally requires.

The affiant remains responsible for the statements made under oath. Knowingly making a material false statement may result in perjury or another offense, depending on the circumstances. The current perjury provision is found in Republic Act No. 11594.

The affidavit should be complete before notarization

A practical affidavit normally contains:

The affiant’s full name and relevant identifying details.
A clear statement that the affiant is competent to testify to the facts stated.
Numbered factual paragraphs, preferably in chronological order.
Facts based on the affiant’s personal knowledge, with the source identified if any statement is based on records.
The specific purpose for which the affidavit is executed.
Clear references to supporting documents or annexes.
The affiant’s signature.
A jurat to be completed by the notary.

Use the exact form prescribed by the court, prosecutor, registry, bank, employer, school, insurer, or government agency receiving the affidavit. A generally valid affidavit can still be rejected if it omits a required statement, attachment, certification, number of copies, or filing form.

Do not leave blank spaces for names, amounts, dates, property descriptions, or other material information. Make corrections before signing, and have material alterations properly addressed. A notary must not notarize a blank or materially incomplete document.

Personal appearance and signing

For a traditional paper affidavit, the affiant must physically appear before the notary at the time of notarization. Because an affidavit ordinarily uses a jurat, the affiant must sign in the notary’s presence and take the oath or affirmation before the notary.

If the affidavit was signed beforehand, tell the notary. The notary may require a fresh unsigned copy or require the affiant to sign again in the notary’s presence. Do not ask the notary to backdate the act: the notarial date should reflect when the affiant actually appeared and took the oath.

Each affiant in a joint affidavit must personally satisfy the requirements. One affiant cannot swear for an absent co-affiant. The Supreme Court has disciplined notaries for treating a call or an unauthorized substitute’s signature as personal appearance; see Tabao v. Lacaba.

Identification requirements

An affiant may be identified in any of the following ways:

The affiant is personally known to the notary

“Personally known” requires genuine prior, firsthand knowledge of the affiant’s identity and circumstances. It is not created merely by an introduction or by meeting the affiant at the appointment.

When the affiant is truly personally known, documentary identification may be unnecessary, but the notarial certificate should state that fact. The Supreme Court explained this exception in Jorge v. Marcelo.

Competent evidence of identity

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

Bring the original current ID and any photocopies requested by the notary. Confirm acceptance beforehand if the ID is digital, has no visible signature, is damaged, contains an old name, or shows details inconsistent with the affidavit. A community tax certificate or cedula alone is not the safe equivalent of the government identification contemplated by the rules.

Credible witnesses

The rules also allow identification through:

One credible witness who is not privy to the document or transaction, is personally known to the notary, and personally knows the affiant; or
Two credible witnesses who are not privy to the document or transaction, personally know the affiant, and establish their own identities through qualifying documentary identification.

This is a structured legal alternative, not a casual arrangement. Ask the notary in advance whether the circumstances and proposed witnesses satisfy the rules.

Jurat versus acknowledgment

Notarial act	What the signer does	Typical use
Jurat	Personally appears, signs before the notary, and swears or affirms that the document’s contents are true	Affidavits, sworn statements and verifications
Acknowledgment	Personally appears and confirms that the signature and execution of the instrument are voluntary	Deeds, contracts, authorizations and similar instruments
Oath or affirmation	Avows the truth under penalty of law; an affirmation may be used instead of a religious oath	Sworn declarations and testimony

An affidavit ordinarily needs a jurat, commonly beginning with “Subscribed and sworn to before me.” An acknowledgment is not interchangeable with a jurat because it does not, by itself, record that the signer swore to the truth of the contents.

What to check in the completed paper affidavit

Before leaving, inspect the entire document. Confirm that:

The affidavit is the same complete document you reviewed and signed.
Your name is spelled consistently throughout.
The venue and actual notarization date are correct.
The jurat, rather than an acknowledgment, was used when an oath was required.
The notary signed and affixed the proper official seal.
The notarial certificate contains the notary’s commission information and required professional details.
The document, page, book, and series entries are present where required.
Every referenced annex is attached, legible, and correctly labeled.
You received the number of originals or certified copies required by the recipient.

A missing register entry, unexplained discrepancy, expired commission, absent affiant, or fabricated notarial details may undermine the document’s public character. The underlying writing does not necessarily become void in every situation, but a defective affidavit may be treated as unsworn or rejected for its intended proceeding.

When the notary must refuse

A notary should not proceed when, among other reasons:

The signer is absent under the traditional paper procedure.
The signer’s identity is not satisfactorily established.
The document is blank or materially incomplete.
The notary knows or has good reason to believe that the document contains false information.
The signer appears unable to understand the act, lacks the required capacity, or is acting under coercion.
The notary is a party to the document, will receive a direct benefit from it, or is disqualified because of the relationship specified in the rules.
The requested act is outside the notary’s authority, territorial jurisdiction, or commission period.

Refusal is a legal safeguard. It should not be solved by looking for someone willing to stamp the same defective document.

Affiants who cannot sign, read, or communicate in the usual manner

Tell the notary before the appointment if the affiant:

Cannot physically sign or make a mark.
Has a visual, hearing, speech, cognitive, or mobility impairment affecting the procedure.
Cannot read the affidavit.
Does not understand the language used.
Needs an interpreter or communication assistance.

The 2004 Rules provide a specific procedure when a person is physically unable to sign or make a mark, including direction to the notary, the presence and signatures of two disinterested witnesses, and prescribed wording. It is not a general method for allowing an absent person or convenient representative to sign.

The affidavit should be in a language the affiant genuinely understands. The receiving institution may separately require English or Filipino, or a certified translation.

Authority and supporting documents

An affidavit should disclose the basis of the affiant’s authority when the person is acting for a corporation, partnership, estate, association, minor, or another individual. Depending on the matter, the recipient may require:

A board or secretary’s certificate.
A special power of attorney.
Letters of administration or guardianship papers.
A government-issued record.
Proof of relationship, employment, ownership, or custody.
Certified copies rather than ordinary photocopies.

Notarization verifies the notarial act; it does not create authority that the affiant never had.

Electronic notarization

The 2025 Rules allow electronic notarization of electronic documents through a separately commissioned Electronic Notary Public, using a Supreme Court-accredited Electronic Notarization Facility.

The two principal modes are:

In-Person Electronic Notarization: The parties physically appear before the electronic notary but execute an electronic document.
Remote Electronic Notarization: The parties appear through live, synchronous videoconferencing within the accredited facility.

Identity verification, electronic signatures, location checks, voluntariness, the electronic notarial certificate and seal, and the electronic notarial record must comply with the rules. A private video call followed by an emailed stamp or scanned signature is not compliant electronic notarization.

Paper documents with wet-ink signatures remain governed by the traditional rules. Notarial wills, depositions, and paper instruments are excluded from the electronic regime, as confirmed in the Supreme Court’s eNotary Services FAQ.

Before using electronic notarization:

Confirm that the receiving court, agency, bank, registry, or foreign institution accepts the electronic document.
Verify that the lawyer has a current electronic notarial commission.
Use an accredited facility, not an ordinary conferencing or file-sharing service.
Keep the original digitally signed file, electronic certificate and seal, verification data, and receipt.
Do not alter, flatten, rescan, or print-and-rescan the completed electronic file unless the recipient specifically instructs you to do so.

Signing while outside the Philippines

If the affiant is abroad, first ask the intended recipient which route it accepts. Common lawful routes include:

Execution before a Philippine embassy or consular officer authorized to perform the relevant notarial service.
Execution before a qualified local notary, followed by an apostille or the required authentication or legalization process.
Limited extraterritorial electronic notarization under the 2025 Rules.

Limited extraterritorial electronic notarization is not available from any private location abroad. At the time of the act, the overseas principal must be within the premises of a Philippine embassy, consular office, or office of a Philippine Honorary Consul, and the other safeguards in the rules must be satisfied.

Apostille and authentication requirements depend on the country of execution, treaty status, document type, and receiving institution. Check the DFA’s current Apostille FAQs and documentary requirements, as well as the relevant Philippine embassy or consulate, before signing.

Deadlines, validity and number of copies

There is no single nationwide expiration period for every affidavit. Its practical usability depends on:

The law or rule governing the transaction.
The filing deadline.
Whether the receiving institution requires a recently executed affidavit.
Whether the stated facts remain true.
Whether the prescribed form has changed.
Whether an original, duplicate original, certified copy, or electronically verifiable file is required.

Notarization does not extend a court, prosecutor, administrative, registration, bidding, benefits, or contractual deadline. Obtain the recipient’s current checklist early and count the applicable filing period separately.

Evidence to preserve

Keep:

The original notarized affidavit or original digitally signed electronic file.
A clear scan or photocopy of the complete document and every annex.
The documents supporting each material factual statement.
Proof of submission, including a receiving stamp, official acknowledgment, tracking record, or electronic confirmation.
The notary’s receipt and contact or commission details.
For electronic notarization, the electronic notarial certificate, seal, verification information, audit record made available to you, and any permitted session recording.
Messages or instructions showing the form and deadline required by the recipient.

Protect copies of identification documents and personal data. Share them only through a channel required for the legitimate transaction.

Common mistakes

Signing a jurat before meeting the traditional notary.
Sending another person to “have it notarized.”
Using an acknowledgment when the document must be sworn.
Relying only on an expired, mismatched, or unsuitable ID.
Leaving blank dates, amounts, names, or property details.
Copying allegations the affiant cannot honestly confirm from personal knowledge.
Omitting required annexes or failing to explain their relevance.
Using inconsistent names, addresses, dates, or civil-status details.
Assuming notarization proves ownership or legal authority.
Asking for a false date or accepting a notarization completed without appearance.
Treating an emailed scan or ordinary online video session as electronic notarization.
Failing to confirm the recipient’s form, deadline, copy, translation, apostille, or electronic-acceptance requirements.

When legal help is urgent

Consult a Philippine lawyer promptly—before signing if possible—when:

A court, prosecutor, regulator, or disciplinary deadline is approaching.
The affidavit concerns a criminal complaint, counter-affidavit, arrest, subpoena, or possible self-incrimination.
Someone is asking you to omit, change, or falsely state a material fact.
The document concerns land, inheritance, corporate authority, large debts, family status, custody, immigration, or a contested transaction.
You are being pressured to sign or do not understand the document.
A signature, seal, commission, or notarization is suspected to be forged or unauthorized.
A filed affidavit contains a material mistake.
The original has been lost or an adverse party is challenging the notarization.
The document will be used abroad or was executed abroad and the authentication route is unclear.

Do not “correct” a filed affidavit by silently replacing pages. Ask the receiving office or counsel whether a supplemental, amended, or corrective affidavit is required.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily a statement made under oath or affirmation, so it generally requires a jurat before a notary or another official legally authorized to administer the oath. A recipient may permit a different sworn-declaration procedure, but that must come from the applicable law, rule, or official form.

Can I bring an affidavit that I already signed?

Bring it, but tell the notary it was pre-signed. For a traditional jurat, the rules require signing in the notary’s presence, so the notary may require a new copy or a fresh signature.

Is one government ID enough?

One current official identification document bearing both photograph and signature can satisfy the general documentary standard. The notary or receiving institution may reasonably request additional proof where names, signatures, appearance, authority, or other details do not match.

Do I need witnesses?

An ordinary affidavit does not automatically require subscribing witnesses. Witnesses may be required by a particular law or form, for identity verification under the credible-witness procedure, or for the special procedure involving a person physically unable to sign or make a mark.

Can my spouse, child, employee, or lawyer appear for me?

Not for the personal oath and signature required from an affiant. A representative may execute a separate affidavit concerning facts personally known to that representative, but should not swear to another person’s personal knowledge.

Can a notary notarize a photocopy or scanned signature?

A paper affidavit should contain the required original signature made through the traditional procedure. An electronic affidavit must be executed and notarized through the compliant electronic process. A pasted signature, scanned seal, or ordinary photocopy is not equivalent to either process.

Does a notarized affidavit expire?

Not automatically under one general rule. The recipient’s regulations, the filing deadline, or changed facts may make an older affidavit unacceptable.

Does notarization guarantee that the affidavit will be accepted?

No. The affidavit must also comply with the substantive law, prescribed form, filing procedure, deadline, attachment requirements, and evidentiary rules applicable to its purpose.
