Quick answer

In the Philippines, an affidavit is generally a written statement of facts made under oath or affirmation. If the document is meant to be an affidavit, the usual notarial act is a jurat: the affiant must personally appear before the notary public, establish identity, sign the affidavit in the notary's presence, and take an oath or affirmation that the statements in it are true. A notary cannot lawfully notarize an affidavit merely because someone sends a signed copy through email or a messaging app. (eLibrary)

For traditional paper notarization, bring the completed affidavit and at least one current identification document issued by an official government agency bearing your photograph and signature, unless the notary personally knows you or the Rules' credible-witness method is properly used. A community tax certificate or cedula alone is not competent evidence of identity under the Notarial Rules. (eLibrary)

Do not sign a traditional affidavit in advance if it will be notarized by jurat. The Rules require the affiant to sign the document in the notary's presence and then take the oath or affirmation. (eLibrary)

Electronic and remote notarization now have a permanent legal framework under the Supreme Court's Rules on Electronic Notarization. But remote notarization is not simply notarization over an ordinary Zoom, Messenger, or video call. It must be performed by a commissioned Electronic Notary Public (ENP) using an accredited Electronic Notarization Facility (ENF) and following the Supreme Court's prescribed identity-verification and videoconferencing procedures. The former 2020 Interim Rules on Remote Notarization of Paper Documents have been repealed. (eLibrary)

What makes a document an affidavit?

An affidavit is more than a signed written statement. Its defining feature is the oath or affirmation.

For an ordinary affidavit, the document normally identifies the affiant, states the relevant facts in a clear and definite manner, contains the affiant's signature, and ends with the appropriate jurat. The exact wording and additional contents may vary depending on what the affidavit will be used for.

The jurat is the notarial portion showing that the affiant personally appeared, was properly identified, signed the document in the notary's presence, and took an oath or affirmation regarding the document. The Supreme Court's 2004 Rules on Notarial Practice expressly require all four elements. (eLibrary)

This is different from an acknowledgment. In an acknowledgment, the person appears before the notary and declares that the signature was voluntarily affixed and that the instrument is his or her free and voluntary act and deed. Acknowledgments commonly appear in deeds, contracts, powers of attorney, and similar instruments. (eLibrary)

An affidavit ordinarily requires a jurat because the affiant is swearing to the truth of the statements, not merely acknowledging a signature.

Requirements for notarizing a paper affidavit

For a traditional notarization under the 2004 Rules on Notarial Practice, the safest practical approach is to satisfy all of the following requirements.

Prepare the complete affidavit before going to the notary. Names, dates, factual allegations, attachments, and other material portions should already be complete. A notary public may not notarize a blank or incomplete instrument or a document without the appropriate notarial certification. (eLibrary)
Personally appear before the commissioned notary public. Sending the document through another person is not a substitute for personal appearance. (eLibrary)
Bring competent proof of identity. The standard rule is at least one current identification document issued by an official agency bearing the person's photograph and signature. (eLibrary)
Do not rely on a cedula alone. The Supreme Court has specifically held that a community tax certificate does not satisfy the competent-evidence-of-identity requirement. (eLibrary)
Sign the affidavit in front of the notary. This is part of the definition of a jurat. (eLibrary)
Take the oath or affirmation. The notary should actually administer the oath or affirmation; merely stamping and signing the document is not enough.
Review the completed jurat and notarial details. The notarial certificate should not have unexplained blanks, particularly in important identification or notarial information. A notary is prohibited from signing or sealing an incomplete notarial certificate. (eLibrary)
Keep a clear copy of the final notarized document and all attachments. For important transactions or litigation, preserve the original whenever possible.

The notary must also make the corresponding entry in the notarial register, including the date and time, type of notarial act, description of the document, principal's identity information, and other required particulars. (eLibrary)

What IDs are acceptable?

The governing concept is competent evidence of identity.

Under the 2004 Rules as amended, this ordinarily means at least one current identification document issued by an official agency bearing the person's photograph and signature. The Rules and Supreme Court decisions identify examples such as passports, driver's licenses, PRC IDs, NBI or police clearances, government-issued employment IDs, SSS and GSIS cards, senior-citizen identification and other qualifying government documents. (eLibrary)

Because the validity and features of particular IDs can change, the safest practice is to bring a current, unexpired government ID with a clear photograph and signature, and preferably a second government ID if available.

If an affiant lacks the ordinary documentary proof of identity, the Rules also recognize identification through qualifying credible witnesses. The requirements differ depending on whether the credible witness is personally known to the notary. The witnesses must meet the conditions imposed by the Rules and cannot simply be companions who happen to know the affiant. (eLibrary)

Is a cedula enough?

Generally, no.

The Supreme Court has repeatedly treated a community tax certificate as inadequate competent evidence of identity because it does not satisfy the required identifying characteristics. A notary should not use a cedula as the sole basis for identifying an affiant who is not personally known to the notary. (eLibrary)

A government office, bank, school, employer, or other receiving institution may separately request a cedula for its own purposes. That is different from saying that a cedula alone satisfies the Supreme Court's notarial identification rules.

Must the affidavit be signed in front of the notary?

For a traditional jurat, yes.

The Supreme Court defines a jurat as involving personal appearance, proper identification, signing in the notary's presence, and taking an oath or affirmation. (eLibrary)

This is one reason people should avoid signing an affidavit at home and simply asking a messenger, relative, employee, or document-processing service to have it notarized later.

A supposed notarization performed while the affiant was absent can expose the document to challenge and the notary to disciplinary consequences. The Supreme Court has repeatedly emphasized that notarization is a public function, not a routine stamping service. (eLibrary)

Where may a traditional notary perform the notarization?

A traditional notary ordinarily performs notarial acts at the notary's regular place of work or business within the territorial jurisdiction covered by the commission.

The Rules recognize limited situations in which notarization may be performed elsewhere within that territorial jurisdiction, including certain public offices or function venues, hospitals or medical institutions where a party is confined, and places where a party is detained. (eLibrary)

Accordingly, a lawyer's status as an attorney does not by itself authorize that lawyer to notarize documents anywhere in the Philippines. Traditional notarial authority depends on a valid notarial commission and its territorial scope.

What should appear in the notarial certificate?

The concluding portion of a traditional notarial certificate contains information that helps establish the notary's authority. Under the Rules, this includes the notary's name as stated in the commission, commission serial number, the city or province of commission, expiration of the commission, office address, Roll of Attorneys number, professional tax receipt information, and IBP membership number. (eLibrary)

Missing notarial particulars do not automatically answer every question about the underlying transaction, but substantial irregularities can become important when the authenticity or evidentiary status of the document is challenged.

Does notarization automatically make everything in an affidavit true?

No.

Notarization establishes the performance of the notarial act; it does not give the notary personal knowledge that every factual allegation in the affidavit is correct.

An affidavit can still be contradicted by documents, witnesses, admissions, electronic records, or other competent evidence. Likewise, notarization does not automatically make an affidavit admissible for every purpose in a court proceeding. The Rules of Evidence, hearsay rules, procedural requirements, and the right of an opposing party to examine a witness may still apply.

A person should therefore never sign an affidavit merely because someone else prepared it or says that it is a "standard form." The affiant is the person swearing to its contents.

Knowingly making material false statements under oath can also create exposure to perjury or other criminal liability, depending on the circumstances. Republic Act No. 11594 increased the penalties governing perjury under Article 183 of the Revised Penal Code. (Lawphil)

Does every document need notarization?

No.

Philippine law does not impose a universal rule that every agreement, declaration, authorization, or private document must be notarized.

For many contracts, notarization affects the document's public character, evidentiary treatment, registration, efficacy against third persons, or compliance with a particular legal requirement rather than the basic existence of the agreement itself. The Supreme Court has repeatedly explained, for example, that defective or absent notarization does not necessarily invalidate an otherwise perfected contract merely because Article 1358 of the Civil Code calls for a public instrument. (eLibrary)

But this principle should not be applied mechanically to affidavits or documents governed by a special statute, procedural rule, registry requirement, or government form. If the particular law requires a sworn affidavit, verified pleading, acknowledged instrument, notarized consent, or public document, failure to use the prescribed form can have serious consequences.

Always identify what the receiving court, agency, registry, bank, embassy, school, employer, or other institution actually requires.

Special rules for judicial affidavits

A Judicial Affidavit used as testimony in court is not simply an ordinary narrative affidavit with a jurat.

Under the Judicial Affidavit Rule, the affidavit must comply with prescribed contents, including information about the witness, the lawyer conducting or supervising the examination, an acknowledgment that the witness is answering under oath and may incur liability for false testimony or perjury, and consecutively numbered questions and answers. The lawyer must also execute the required sworn attestation concerning the examination. (eLibrary)

As a general rule under the Judicial Affidavit Rule, judicial affidavits and the accompanying documentary or object evidence must be filed and served not later than five days before the pre-trial, preliminary conference, or scheduled hearing for motions and incidents, subject to the Rule's scope, exceptions, and provisions on late submission. (eLibrary)

The Rule does not apply identically to every Philippine proceeding, so litigants should follow the particular court's applicable procedural rules and orders rather than treating an ordinary affidavit as a substitute for a judicial affidavit.

Can an affidavit now be notarized online?

Potentially, but only through the Supreme Court's electronic-notarization system.

A.M. No. 24-10-14-SC created In-Person Electronic Notarization (IEN) and Remote Electronic Notarization (REN) for electronic documents. REN treats qualifying real-time virtual appearance through the prescribed system as the equivalent of physical appearance. Pre-recorded videos are prohibited. The process requires identity verification and must use an accredited ENF. (eLibrary)

The electronic-notarization framework applies to electronic documents in PDF or PDF/A form. Traditional paper documents bearing handwritten signatures continue to be governed by the 2004 Notarial Rules. Notarial wills and depositions are excluded from the electronic-notarization regime. (Supreme Court of the Philippines)

The Supreme Court opened applications for Electronic Notary Public commissions on August 10, 2026, as part of the continuing rollout of the system. Anyone seeking electronic notarization should verify that the lawyer is actually commissioned as an ENP and that an accredited facility is being used. (Supreme Court of the Philippines)

A lawyer who merely asks you to appear on an ordinary video call and then stamps a paper document is not thereby complying with the Rules on Electronic Notarization.

Affidavits executed abroad

The requirements depend heavily on where the affidavit is executed and where it will be used.

A Filipino abroad may, depending on the circumstances, execute an affidavit before an authorized Philippine Embassy or Consulate. Philippine foreign-service posts commonly require personal appearance, the document to be notarized, and valid passport or identification documents, although the exact requirements and appointments differ by post. (Vientiane PE)

A document notarized or issued abroad may instead require an apostille or other authentication depending on the country involved and the receiving Philippine institution.

Conversely, a Philippine notarized affidavit intended for use abroad may need a Certificate of Authority for a Notarial Act (CANA) from the appropriate Regional Trial Court and an Apostille from the Department of Foreign Affairs, depending on the document and destination. DFA's authentication requirements expressly identify CANA requirements for various notarized affidavits and private documents. (DFA Consular Services)

Do not obtain an apostille merely because a document is notarized. First confirm the requirements of the foreign authority that will receive it.

Evidence worth preserving

Keep the original notarized affidavit whenever possible, together with a high-resolution scan of every page and attachment. Preserve the IDs or identification records used at the time, drafts showing what was actually reviewed before signing, emails or messages transmitting supporting documents, and any acknowledgment or receiving copy from the agency or person to whom the affidavit was submitted.

If authenticity may later become disputed, also preserve evidence establishing when and where the document was executed and who was present. Do not alter the notarized original after execution. If a material fact must be changed, preparing and properly executing a corrected or supplemental affidavit is ordinarily safer than making handwritten alterations to the completed document.

Common mistakes to avoid

Signing before appearing before the notary. For a jurat, the affiant must sign in the notary's presence.

Sending another person to obtain the notarization. Personal appearance cannot ordinarily be delegated.

Using only a cedula for identification. A community tax certificate alone is not competent evidence of identity under the governing rule.

Signing an affidavit containing blanks. Philippine notarial rules prohibit notarization of blank or incomplete instruments. (eLibrary)

Ignoring the difference between a jurat and an acknowledgment. An affidavit ordinarily involves an oath and therefore calls for a jurat. A deed or contract may instead require acknowledgment.

Assuming notarization proves the truth of the contents. It does not.

Using an ordinary video call as "online notarization." Valid electronic notarization must comply with A.M. No. 24-10-14-SC and use a commissioned ENP and accredited ENF.

Using an ordinary affidavit when a judicial affidavit is required. Court testimony governed by the Judicial Affidavit Rule has substantially more detailed requirements.

Assuming a Philippine notarized affidavit is automatically usable overseas. Apostille, CANA, translation, legalization, or destination-country requirements may still apply.

When legal help is urgent

Prompt legal review is advisable when an affidavit concerns a pending criminal complaint, preliminary investigation, court case, administrative proceeding, employment investigation, property ownership dispute, inheritance, fraud allegation, substantial financial transaction, immigration matter, custody dispute, or any situation in which admissions in the affidavit could later be used against the affiant.

Legal advice is also important if you are being asked to sign facts you cannot personally verify, backdate an affidavit, omit material facts, sign a blank document, pretend that you appeared before a notary when you did not, or execute another affidavit contradicting a previous sworn statement.

If a questionable affidavit has already been filed or submitted, avoid attempting to "fix" the record informally. The proper response may involve a supplemental affidavit, correction, withdrawal, explanation, motion, or other procedure depending on where the document was used.

Frequently asked questions

Can I bring an affidavit that I drafted myself?

Yes. There is no general rule requiring every ordinary affidavit to be drafted by a lawyer. But the affidavit must accurately state the relevant facts and comply with whatever substantive or procedural requirements govern its intended use.

For legally significant matters, professional drafting can help avoid unnecessary admissions, missing facts, defective wording, or use of the wrong type of affidavit.

Can I sign the affidavit before going to the notary?

For a traditional affidavit requiring a jurat, you should not. The Rules require signing in the notary's presence. (eLibrary)

Is one valid government ID enough?

The governing rule generally permits at least one current official identification document bearing the person's photograph and signature. A notary or receiving institution may reasonably seek additional identification where necessary to resolve discrepancies or establish identity securely. (eLibrary)

Can the notary use my cedula as my only ID?

A cedula alone should not be treated as competent evidence of identity. The Supreme Court has specifically rejected that practice. (eLibrary)

Do I need witnesses for every affidavit?

Not ordinarily merely because the document is an affidavit. The basic jurat involves the affiant and notary. Witnesses may nevertheless be required by a particular law, form, transaction, or as part of the Rules' credible-witness procedure for establishing identity.

Can a notary notarize a photocopy or scanned signature sent to the office?

Not as an ordinary traditional jurat where the person did not personally appear and sign before the notary. Electronic notarization is governed by a separate Supreme Court framework and must comply with its technical and commissioning requirements. (eLibrary)

Is an improperly notarized affidavit automatically void?

There is no single answer for every document. A defective notarization can destroy the legal presumptions or public character associated with proper notarization. Whether the underlying document remains effective depends on the nature of the document and the law requiring it.

Where the law specifically requires a sworn affidavit or particular notarial form, the defect may have more serious procedural or substantive consequences than it would for an ordinary contract.

Can an affidavit be used as court testimony?

Sometimes, but not simply because it is notarized. When the Judicial Affidavit Rule applies, the prescribed judicial-affidavit format and filing requirements must be followed. Other evidentiary and procedural rules also continue to apply. (eLibrary)

Is remote notarization already recognized in the Philippines?

Yes. The Rules on Electronic Notarization are legally in force, but the notarization must be performed through the system contemplated by those Rules. The Supreme Court's current implementation materials should be checked for commissioned ENPs and accredited facilities. (eLibrary)
