Quick answer

A Philippine affidavit should state facts within the affiant’s personal knowledge, identify the affiant and the document’s purpose, and end with the affiant’s signature and a jurat. For a traditional paper affidavit, the affiant must personally appear before a duly commissioned notary public, present competent proof of identity, sign in the notary’s presence, and take an oath or affirmation that the statements are true.

Do not sign the affidavit beforehand unless the notary specifically instructs you to do so in a procedure permitted by law. A representative, relative, liaison, or fixer cannot appear and take the oath for the affiant.

Electronic notarization is now legally recognized for qualifying electronic documents, but it must be performed by a commissioned Electronic Notary Public through an accredited electronic-notarization facility. An ordinary video call, emailed scan, or pasted digital image of a notarial seal is not electronic notarization.

The essential requirements

For an ordinary paper affidavit, prepare:

The correct affidavit or agency-prescribed form;
The affiant’s complete and accurate identifying details;
A clear, chronological statement of relevant facts;
Copies of records referred to in the affidavit, properly identified as annexes when necessary;
The unsigned final document, with no material blanks;
At least one current identification document issued by an official agency and bearing the affiant’s photograph and signature;
The original ID for inspection and, if requested, a photocopy;
Any document proving authority to act for another person or organization; and
Enough original copies for the receiving office, the affiant, and any other required recipient.

The receiving court, prosecutor, government agency, bank, school, insurer, employer, or private institution may impose additional requirements. Obtain its current checklist before drafting or notarizing the affidavit.

What the affidavit should contain

There is no single universal form for every affidavit. Its contents depend on its purpose, but a properly prepared affidavit ordinarily contains:

Caption or title. This should accurately describe the affidavit, such as an Affidavit of Loss, Affidavit of Discrepancy, Complaint-Affidavit, Counter-Affidavit, or Affidavit of Support.
Affiant’s identity. State the affiant’s full legal name and the identifying details relevant to the transaction. Avoid unnecessary sensitive information when the receiving office does not require it.
Opening oath clause. The document usually states that the affiant, after being duly sworn, declares the following facts.
Numbered factual statements. State facts in the first person, preferably in chronological order. Separate distinct facts into numbered paragraphs.
Basis of knowledge. Distinguish what the affiant personally saw, heard, did, received, or recorded from information learned from another person. Do not present assumptions or hearsay as personal knowledge.
Purpose. Explain why the affidavit is being executed and where it will be submitted.
Annexes. Identify supporting records consistently—for example, “a copy is attached as Annex ‘A.’” Check that every cited annex is actually attached and legible.
Signature block. Use the same name and signature reflected in the affiant’s identification records. Explain any material name discrepancy in the document or through appropriate supporting records.
Jurat. The notary completes this portion only after identifying the affiant, witnessing the signature, and administering the oath or affirmation.

Use the receiving office’s official form when one exists. A generic internet template may omit a statement, certification, witness, or attachment required for the particular transaction.

Jurat versus acknowledgment

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

For 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 that the affidavit’s contents are true.

An acknowledgment is generally used for deeds, contracts, powers of attorney, and similar instruments. The signer appears before the notary and confirms that the signature was voluntarily affixed and that the document is the signer’s free and voluntary act. An acknowledged document may have been signed earlier; an affidavit requiring a jurat must be signed in the notary’s presence.

Using the wrong notarial certificate can create questions about whether the required oath was actually administered. These requirements come from the Supreme Court’s 2004 Rules on Notarial Practice.

Personal appearance is mandatory

For traditional notarization, the affiant must be physically present before the notary at the time of notarization. The Supreme Court has repeatedly disciplined notaries who notarized documents without the signer’s personal appearance. The rule exists so the notary can verify identity, witness the signing, administer the oath, and assess whether the act is voluntary.

Traditional notarial acts are normally performed at the notary’s regular place of work or business and within the city or province covered by the commission. Limited exceptions may apply to authorized off-site notarization, but a notary cannot disregard territorial and personal-appearance requirements merely for convenience.

A notary should refuse to proceed if, among other reasons:

The document is blank or materially incomplete;
The affiant is absent;
Identity cannot be satisfactorily established;
The affiant does not appear to understand the document;
The signature or oath is not voluntary;
The transaction appears unlawful or immoral; or
The notary is disqualified because of a prohibited interest or relationship.

What identification is sufficient?

Under the traditional rules, competent evidence of identity generally means at least one current identification document issued by an official agency and bearing the individual’s photograph and signature. Examples recognized by the Rules include passports, driver’s licenses, PRC IDs, SSS or GSIS cards, senior-citizen IDs, seafarer records, alien-registration documents, and qualifying government-office IDs. The list is not exclusive, but the ID must satisfy the governing criteria.

A community tax certificate or cedula is not competent evidence of identity by itself. The Supreme Court has explained that it lacks the safeguards required for reliable identification. A birth certificate also does not ordinarily satisfy the photo-and-signature requirement by itself.

A PhilID, ePhilID, or other digital government credential should be capable of official verification. Because formats differ and some do not display a handwritten signature, bring another current government-issued ID when available and confirm the notary’s verification procedure in advance.

If the affiant has no qualifying ID, the Rules permit identification through credible witnesses:

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.

The notary must record how identity was established. The controlling definition appears in the Supreme Court’s 2008 amendment on competent evidence of identity.

What should happen at the notary’s office?

A proper traditional notarization should generally proceed as follows:

The notary reviews the complete affidavit and its attachments.
The affiant presents the original identification document.
The notary verifies the affiant’s identity and willingness to sign.
The affiant signs the affidavit in the notary’s presence.
The notary administers an oath or affirmation.
The affiant signs or places the permitted mark in the notarial register.
The notary completes the jurat, signs it, affixes the official seal, and records the act.
The notarized document receives its document, page, book, and series details.

Before leaving, check that:

The affidavit and every annex are complete;
The signing and notarization dates are correct;
The jurat identifies the evidence of identity when required;
The notary’s seal and signature are legible;
The notary’s name, commission details, office address, Roll of Attorneys number, and other required particulars appear;
The document, page, book, and series numbers are filled in; and
No material blank remains in the affidavit or notarial certificate.

Never agree to backdating or future-dating.

Electronic and remote notarization

The Supreme Court’s 2025 Rules on Electronic Notarization supplement traditional notarization. They cover electronic documents through:

In-person electronic notarization, where the principal physically appears before an Electronic Notary Public; and
Remote electronic notarization, where the principal appears through the audio-video system of an accredited Electronic Notarization Facility.

An electronic affidavit should be in the required PDF or PDF/A format and signed electronically through the authorized system. For an electronic jurat, the affiant must electronically sign in the Electronic Notary Public’s view and take the required oath or affirmation.

The electronic rules do not apply to notarial wills, depositions, or paper documents bearing wet signatures or handwritten marks. They also repealed the pandemic-era interim rules for remotely notarizing paper documents. Consequently, emailing a scan of a wet-signed affidavit and joining an informal video call is not a substitute for compliant notarization.

Remote electronic notarization for a principal outside the Philippines is subject to the Rules’ conditions, including applicable location and consular requirements. Confirm eligibility with the Electronic Notary Public before relying on that route.

Availability depends on commissioned Electronic Notaries Public and accredited facilities. Check the Supreme Court’s eNotary Services portal rather than relying solely on a provider’s advertisement.

Your electronic copy after traditional notarization

The 2025 amendments to the traditional Notarial Rules introduced digital recordkeeping and transmission safeguards. The amended provisions direct the notary, at no additional cost, to transmit an electronic duplicate to each signatory through email or another mutually agreed file-sharing method within the prescribed period—generally within five days from completion of the notarial act or from the applicable deadline for transmitting the duplicate original to the clerk of court.

A signatory may waive that transmittal, but the Rules attach consequences to the waiver concerning objections to the reproduction’s completeness. It is normally safer to receive and review the electronic copy.

Compare it immediately with the document in your possession. If there is a material discrepancy affecting anyone’s rights, notify the notary promptly in writing, identify every discrepancy, request correction, and preserve proof that the notice was sent.

Special situations

Affidavits for courts

An ordinary affidavit is not automatically a judicial affidavit. Under the Judicial Affidavit Rule, a judicial affidavit must use consecutively numbered questions and answers, identify the examining lawyer and place of examination, establish the witness’s personal knowledge, identify exhibits, contain a jurat, and include the lawyer’s sworn attestation against coaching.

Generally, judicial affidavits and exhibits must be filed and served no later than five days before the pretrial, preliminary conference, or scheduled hearing for motions and incidents. The Rule does not apply to small-claims cases.

In criminal actions, the Rule applies when the maximum imposable penalty does not exceed six years, when the accused agrees regardless of the penalty, or as to the civil aspect regardless of the penalty. Special prosecution and defense deadlines also apply. A witness must ordinarily appear for cross-examination; notarization alone does not make the affidavit a substitute for required testimony.

Affidavits signed for an organization

A corporate officer, association officer, attorney-in-fact, guardian, or other representative must establish both personal identity and authority to act. Depending on the document and receiving office, this may require a board resolution, secretary’s certificate, special power of attorney, court order, or other authority.

Do not claim representative authority that the supporting document does not actually grant.

Joint affidavits

Every affiant must personally appear, be separately identified, sign in the notary’s presence, and take the oath. One person’s appearance cannot cure another affiant’s absence.

“Disinterested witnesses” required by a particular statute, agency, or form must genuinely be disinterested and competent to state the relevant facts. Their signatures are not a formality.

Affiants who cannot read, understand the language, or sign normally

Tell the notary before the appointment. Translation, explanation, witnesses, thumbmarks, or other safeguards may be required. The notary should not proceed unless satisfied that the affidavit is understood and voluntary.

When age, illness, disability, medication, or cognitive condition may affect capacity, obtain legal advice before execution. Medical documentation or additional witnesses may be prudent, but they do not replace the notary’s duties.

Documents executed abroad

An affidavit for use in the Philippines may be executed before a Philippine embassy or consulate that provides notarial services. Another route may involve notarization under the foreign country’s law followed by an apostille, if the country is a party to the Apostille Convention, or the applicable authentication and legalization process if it is not.

Requirements differ by country and receiving office. Consult the relevant Philippine foreign-service post and the DFA’s Apostille documentary requirements. An apostille authenticates the origin of the public document or notarial act; it does not certify that the affidavit’s factual statements are true.

What notarization does—and does not do

Proper notarization converts a private document into a public document for evidentiary purposes and gives it a presumption concerning authenticity and due execution. A defective notarization may strip the document of that public character and leave it as a private document. The Supreme Court explains these consequences in Yap-Paras v. Paras.

Notarization does not:

Prove that every factual statement is true;
Establish ownership, authority, capacity, or entitlement that does not otherwise exist;
Cure an unlawful transaction or defective underlying document;
Replace filing, service, registration, apostille, publication, or agency approval;
Extend a filing deadline; or
Guarantee that a court or agency will accept the affidavit.

In court proceedings, an affidavit may still be treated as hearsay if the affiant does not testify and cannot be cross-examined, unless a rule or recognized exception permits its use. Notarization addresses execution and authenticity; it does not automatically establish admissibility or evidentiary weight for every purpose.

False statements and possible liability

An affiant must not deliberately state a material falsehood, conceal a material fact while creating a misleading statement, or swear to facts that the affiant has no basis to assert.

Under Republic Act No. 11594, perjury involving a knowingly false material statement under oath is punishable by prision mayor in its minimum period. The statute provides additional consequences involving public officers or employees, including an enhanced period of imprisonment, a fine of up to ₱1 million, and perpetual absolute disqualification under the circumstances stated in the law.

Not every factual error is automatically perjury. The prosecution must establish, among other elements, a willful and deliberate assertion of a material falsehood before a competent officer for a legally required or legal purpose. Correct genuine mistakes promptly and do not alter a notarized document informally.

Evidence and records to preserve

Keep:

The complete notarized original;
A clear color scan of the entire affidavit and all annexes;
The electronic duplicate transmitted by the notary;
The document, page, book, and series numbers;
The notary’s name, office address, commission number, and commission expiry;
The payment receipt and appointment communications;
The receiving office’s form and written requirements;
Source records supporting each material statement;
Relevant emails, messages, photographs, receipts, reports, and contemporaneous notes;
Proof of submission, filing, service, or delivery; and
Written notice of any discrepancy or correction request.

Store identification records securely. Avoid sending full ID images through unverified social-media accounts or to people who merely claim to arrange notarization.

If authenticity is disputed, the Office of the Clerk of Court of the Regional Trial Court that supervises the notary’s commission may be asked to verify the commission and relevant notarial records.

Common mistakes to avoid

Signing before meeting the notary when a jurat is required;
Sending another person to “process” the oath;
Using an acknowledgment instead of a jurat;
Presenting only a cedula, expired ID, photocopy, company ID, or unsupported digital image;
Leaving dates, amounts, names, annex references, or ID details blank;
Attaching an annex after notarization without proper re-execution;
Using a generic affidavit instead of the receiving office’s mandatory form;
Swearing to another person’s account as if personally witnessed;
Failing to disclose uncertainty or limits of memory;
Using inconsistent names, dates, addresses, or document numbers;
Altering the document after it has been notarized;
Relying on an uncommissioned or fake notary;
Assuming notarization satisfies a separate filing or registration deadline; and
Treating an emailed scan or informal video call as valid electronic notarization.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A court, prosecutor, regulator, immigration office, or law-enforcement agency has imposed a deadline;
The affidavit concerns criminal accusations, arrest, detention, domestic violence, child safety, immigration status, or possible deportation;
It concerns land, inheritance, substantial debt, corporate control, insurance proceeds, or waiver of rights;
Someone is pressuring you to sign, omit facts, backdate, or make a statement you cannot verify;
A signature, seal, notarial entry, ID, or electronic copy appears forged or altered;
You have already submitted a materially incorrect affidavit;
The affiant may lack capacity or cannot communicate independently;
The document must be used abroad or was executed abroad; or
A filing date is near and the receiving office has rejected the affidavit.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily a sworn statement, so it must be made under oath or affirmation before a notary or another officer authorized by law. A receiving office may use a different form of verified declaration only when its governing law or rules permit it.

How many IDs are required?

The traditional rule generally permits one current official ID bearing the affiant’s photograph and signature. A notary or receiving office may reasonably request additional identification when names differ, authenticity is uncertain, or its own rules require more.

Is a cedula enough?

No. A community tax certificate is not competent evidence of identity by itself for notarization.

Can the affidavit be signed at home and brought to the notary?

Not when a jurat is required. The affiant must sign in the notary’s presence. Limited authorized procedures exist for electronic notarization and exceptional off-site traditional acts, but a pre-signed paper affidavit delivered by another person is improper.

Can an affidavit be notarized online?

Yes, if it is a qualifying electronic document and the entire process complies with the 2025 Electronic Notarization Rules through a commissioned Electronic Notary Public and accredited facility. A scanned wet-signed affidavit and ordinary video call are insufficient.

Does a notarized affidavit expire?

There is no universal expiry period for all affidavits. Its usefulness may end when the facts change, and a receiving office may require one executed within a specified period. Check the current requirement for the particular transaction.

Can a notary prepare the affidavit?

A commissioned notary is a lawyer and may separately provide drafting services, subject to professional duties and conflicts. Drafting and notarization are distinct functions. The affiant remains responsible for reviewing and truthfully swearing to the final contents.

Does notarization guarantee acceptance?

No. The affidavit may still be rejected for using the wrong form, lacking attachments or authority, containing inconsistent facts, missing a filing deadline, or failing another substantive requirement.
