Quick answer

An affidavit is a written statement of facts that the maker—the affiant—swears or solemnly affirms to be true before a person authorized to administer oaths. For a traditional paper affidavit in the Philippines, the usual requirements are:

A complete and accurate written statement;
The affiant’s signature, placed in the notary public’s presence;
The affiant’s personal appearance before the notary;
Proper identification through competent evidence of identity, unless personally known to the notary;
An oath or affirmation administered by the notary; and
A completed jurat, including the notary’s signature, seal, commission details, and notarial-register information.

Do not sign a paper affidavit in advance unless the notary expressly instructs you otherwise. A jurat requires signing in the notary’s presence. The notary must personally perform the notarial act; an assistant, secretary, or staff member cannot administer the oath or complete the notarization.

Electronic notarization is also legally recognized, but only through a duly commissioned Electronic Notary Public using the system and procedures authorized by the Supreme Court. An ordinary video call, emailed scan, pasted signature, or commercial e-signing application does not by itself create a valid electronic notarization.

What an affidavit does—and does not do

An affidavit records facts under oath. Common examples include affidavits of loss, discrepancy, consent, support, residency, identity, complaint, desistance, and one-and-the-same-person affidavits.

The affidavit should state facts the affiant personally knows or clearly identify information based on authentic records. It should not present guesses, legal conclusions, hearsay, or another person’s story as firsthand knowledge.

Notarization does not automatically prove that every factual statement is true. It confirms the legally significant acts covered by the notarial certificate, such as the affiant’s appearance, identification, signature, and oath. The Supreme Court has clarified that it is principally the acknowledgment, affirmation, oath, or jurat portion—not every assertion in the document—that enjoys the relevant presumption of regularity. See G.R. No. 253527, October 21, 2024.

An affidavit may also remain subject to the rules on admissibility and hearsay. In court, notarization does not necessarily eliminate the need for the affiant to testify and undergo cross-examination.

Essential contents of an affidavit

Requirements vary according to the affidavit’s purpose and the rules of the receiving court, agency, bank, school, employer, registry, or private institution. A properly prepared general affidavit usually contains:

Title or caption. This identifies the kind of affidavit or the proceeding in which it will be used.
Affiant’s identifying details. These commonly include the full legal name, age or statement of legal age, citizenship, civil status when relevant, and complete address.
Statement of capacity and personal knowledge. The affidavit should explain who the affiant is and why the affiant knows the stated facts.
Clear factual allegations. Numbered paragraphs are preferable. Include relevant names, dates, locations, document numbers, and events, but only when accurate.
Purpose clause. State why the affidavit is being executed, particularly when a government office or private institution requires it.
Supporting attachments. Identify each attached document accurately—for example, “a copy is attached as Annex ‘A.’” Never describe a copy as an original or certified copy unless that is true.
Affiant’s signature and printed name.
Jurat. The jurat records that the affiant appeared, was properly identified, signed in the notary’s presence, and took an oath or affirmation.

A form supplied by the receiving institution should ordinarily be followed. Do not assume that a generic affidavit will satisfy a specialized requirement such as a judicial affidavit, affidavit of self-adjudication, affidavit supporting a criminal complaint, immigration document, or travel-consent affidavit.

The jurat is normally required for an affidavit

A jurat is different from an acknowledgment.

For a jurat, the individual must, on a single occasion:

Personally appear before the notary public;
Present the document;
Be personally known to the notary or identified through competent evidence of identity;
Sign the document in the notary’s presence; and
Take an oath or affirmation concerning the document.

These elements come from the Supreme Court’s notarial rules and have repeatedly been enforced in disciplinary decisions. See A.C. No. 10783, October 14, 2015.

An acknowledgment, by comparison, is generally used when a person declares before the notary that the person voluntarily executed an instrument as a free act and deed. It is common in contracts, deeds, and powers of attorney. The correct certificate depends on the document and the act required by law. Simply replacing a jurat with an acknowledgment—or vice versa—can create problems.

Personal appearance for paper notarization

For a paper affidavit with a handwritten signature, the affiant must ordinarily be physically present before the commissioned notary at the time of notarization. A relative, employee, agent, or messenger cannot appear in the affiant’s place.

The Supreme Court treats personal appearance as a basic safeguard against forgery, impersonation, coercion, and unauthorized execution. A paper document is not validly notarized merely because:

It was delivered to the notary’s office;
The notary recognizes the signature;
A staff member witnessed the signing;
The affiant spoke with the notary by telephone;
The affiant joined an ordinary video call; or
Someone later presented the affiant’s identification.

The Court has expressly rejected notarization without the signatory’s personal presence under the traditional rules. See A.C. No. 9417, November 18, 2020 and A.C. No. 9269, March 13, 2019.

Acceptable identification

If the notary does not personally know the affiant, the traditional rules require competent evidence of identity. The usual documentary method is at least one current identification document issued by an official agency bearing the holder’s photograph and signature.

Examples recognized in the notarial rules include government-issued documents such as a passport, driver’s license, PRC ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen card, government-office ID, seaman’s book, or alien registration document. The Philippine Identification System Act also requires acceptance of the Philippine Identification Card and prescribed alternative proof, subject to authentication under applicable rules.

Bring the original ID, not merely a photograph or unverified photocopy. The name and signature should match the affidavit. If they do not, bring reliable supporting records and explain the discrepancy before notarization.

A community tax certificate or cedula alone is not competent evidence of identity under the amended definition. The Supreme Court has emphasized this point because a cedula does not provide the required photograph-and-signature safeguards. See A.C. No. 8574, August 16, 2017.

Where ordinary documentary identification is genuinely unavailable, the rules provide a credible-witness method. Depending on whether the credible witness is personally known to the notary, one or two disinterested witnesses may be required, together with the prescribed oaths and identification. Because the details matter, arrange this directly with the notary before the appointment; bringing a friend without prior coordination is not automatically sufficient.

A notary may request additional identification when reasonably necessary to verify identity, capacity, or authority.

The notary must be properly commissioned

A Philippine notary public is a lawyer holding a current notarial commission from the proper court. Traditional notarial authority is territorial: the notary ordinarily performs notarial acts within the territorial jurisdiction covered by the commission.

Before proceeding, check that the notary’s displayed commission is current and that the notarial certificate contains the required details. These generally include:

The notary’s name and signature;
The notarial commission number;
The place and expiration of the commission;
Roll of Attorneys number;
IBP membership information;
Professional Tax Receipt information, when applicable;
Office address;
The document, page, book, and series numbers; and
The official notarial seal.

The details must correspond to the actual act. Never agree to a blank, backdated, postdated, or pre-signed notarial certificate.

What the notary must check

A notary is not merely a signature witness. The notary should determine that:

The affiant personally appeared;
The affiant’s identity was properly established;
The document is complete;
The affiant understands the document and is acting voluntarily;
The affiant has the apparent capacity to execute it;
The signature or mark was properly made;
The oath or affirmation was administered;
The notarial certificate matches the act performed; and
The transaction is entered in the notarial register.

A notary must refuse when the required personal appearance or identification is missing, the document is blank or incomplete, the affiant appears unable to understand or act freely, the transaction is unlawful, or the notary is disqualified by a prohibited interest or relationship.

Step-by-step preparation

1. Confirm the receiving party’s exact requirements

Ask for the official form, checklist, filing method, number of copies, required attachments, language, date limits, and whether electronic notarization is accepted.

There is no single nationwide filing deadline or validity period for all affidavits. A deadline may come from a statute, court rule, agency issuance, contract, notice, or the receiving institution’s current policy. An affidavit may also be rejected as stale when it is supposed to describe present circumstances.

2. Gather reliable source documents

Collect records supporting the factual statements, such as:

Government IDs;
Civil-registry certificates;
Police or incident reports;
Receipts and official correspondence;
Contracts, account records, or certificates;
Photographs, messages, and emails;
Proof of ownership or authority; and
Documents explaining any name, date, or address discrepancy.

Use originals or properly certified copies when the receiving party requires them.

3. Draft only facts you can truthfully swear to

Use short, chronological paragraphs. Distinguish what you personally observed from what records show. If a date or detail is uncertain, do not invent precision. Verify it or state the limitation accurately.

4. Review every page and attachment

Check names, dates, addresses, reference numbers, annex labels, and the purpose clause. Remove blank spaces that could be filled later. Material handwritten corrections should be addressed before notarization and, if accepted, properly initialed by the relevant persons.

5. Appear before the notary with the unsigned affidavit

Bring the complete document, attachments, original valid ID, and any proof of representative authority. Every affiant must appear and sign separately unless a valid electronic-notarization procedure applies.

6. Take the oath or affirmation

The affiant must understand that the statements are being made under oath. A person who objects to a religious oath may make a solemn affirmation instead; it has the same legal effect.

7. Inspect the completed notarization

Before leaving, verify that the date and place are correct, the jurat is complete, the notary signed and sealed the document, and no required page or annex is missing.

8. Preserve copies and proof of submission

Keep a complete scan or photocopy showing every signed page, attachment, seal, and notarial certificate. Retain the filing receipt, email acknowledgment, courier proof, reference number, or stamped receiving copy.

Multiple affiants, representatives, and persons needing assistance

Each affiant must personally satisfy the requirements. One person cannot take another person’s oath or sign another person’s affidavit simply because that person holds a power of attorney. A representative may swear only to facts within the representative’s own knowledge and authority.

If the affiant cannot sign and must use a thumbmark or other mark, cannot read, does not understand the document’s language, or has a disability affecting communication, tell the notary beforehand. Special safeguards, witnesses, interpretation, or another legally appropriate procedure may be necessary.

Do not use a document in a language the affiant does not understand without a reliable translation or explanation. Specialized filings may expressly require a translation.

Judicial affidavits are different

A judicial affidavit is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, it generally takes the form of consecutively numbered questions and answers and must contain specified information about the witness, the examining lawyer, the witness’s personal knowledge, and documentary or object evidence.

It must also contain:

The witness’s signature;
A jurat signed by the notary or another officer authorized to administer the oath; and
The examining lawyer’s sworn attestation that the questions and answers were faithfully recorded and that the witness was not coached.

Filing and service deadlines depend on the nature and stage of the case. For example, the Judicial Affidavit Rule contains specific pre-trial requirements and consequences for late submission. Court orders, special procedural rules, and electronic-filing requirements may also apply. Anyone preparing evidence for a pending case should follow counsel’s instructions and the current court order rather than rely on a general affidavit template. See the Judicial Affidavit Rule, A.M. No. 12-8-8-SC.

Electronic notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, effective in 2025, supplement traditional paper notarization. They cover electronic documents through:

In-Person Electronic Notarization: The principal and required witnesses physically appear before an Electronic Notary Public, while the document and signatures are handled electronically through the authorized facility.
Remote Electronic Notarization: Appearance occurs through the accredited facility’s synchronous audiovisual and identity-verification system.

For an electronic jurat, the affiant must use the prescribed electronic process, sign in the Electronic Notary Public’s full view, and take the oath or affirmation. The Electronic Notary Public then completes the electronic certificate and applies the authorized electronic signature and seal.

Electronic notarization is not accomplished by casually emailing a signed scan or meeting a traditional notary on Zoom, Messenger, or another general videoconferencing service. Confirm that:

The lawyer has a current electronic notarial commission;
A Supreme Court-accredited Electronic Notarization Facility is being used;
The document is in the prescribed electronic format;
Identity, location, consent, and appearance checks are completed; and
The receiving court, agency, registry, bank, or institution will accept the electronic document.

The Supreme Court’s eNotarization FAQs provide current public guidance.

An electronic notarial act for a principal outside the Philippines is permitted only under the rules’ limited extraterritorial arrangement. At the time of the act, the principal must be within the premises of a Philippine embassy, Philippine consular office, or office of a Philippine honorary consul. This is not a general authorization to use Philippine electronic notarization from any overseas location.

Affidavits executed abroad

A document signed abroad for use in the Philippines may follow one of several routes, depending on the country, document, and receiving institution:

Execution before a Philippine embassy or consulate authorized to provide the relevant notarial service;
Notarization before a competent local notary followed by an apostille from the country’s designated authority, if both countries use the Apostille Convention and no exception applies; or
Authentication or legalization under the procedure applicable to a non-Apostille country or a document excluded from apostille treatment.

An apostille authenticates the origin of the public document or notarial certification; it does not certify that the affidavit’s factual contents are true. Requirements, appointments, fees, translations, witnesses, and accepted identification differ by diplomatic post and country. Check the relevant Philippine embassy or consulate and the Philippine Department of Foreign Affairs before signing.

Fees and processing time

There is no single uniform private-notary fee for every affidavit nationwide. Charges may vary by locality, document type, number of signatories and copies, complexity, and applicable local or IBP guidance. Consular and electronic-notarization fees follow their respective official schedules.

Ask for the total charge before proceeding and request a receipt. Be cautious of unusually cheap “notarization” offered without appearance, identity verification, an oath, or a properly commissioned notary.

There is likewise no universal processing period. A straightforward affidavit may be completed during the appointment, but drafting, identity issues, special witnesses, electronic verification, apostille processing, or institution-specific review may take longer.

Common mistakes to avoid

Signing a paper affidavit before appearing for the jurat;
Sending someone else to have it notarized;
Relying only on a cedula;
Using an expired, damaged, altered, or mismatched ID;
Leaving material blanks in the document;
Backdating or postdating the affidavit or jurat;
Copying a form that does not match the transaction;
Stating assumptions or another person’s account as personal knowledge;
Attaching incomplete, altered, or falsely described records;
Using an acknowledgment when a jurat is required;
Accepting notarization performed entirely by office staff;
Treating an ordinary video call or scanned signature as electronic notarization;
Failing to check the notary’s commission and territorial authority;
Assuming notarization makes an unlawful or defective transaction valid;
Assuming every affidavit has the same filing deadline; and
Submitting the only copy without preserving a complete duplicate and proof of filing.

If the notarization appears defective or fraudulent

Preserve the original document and do not alter it. Make clear copies of:

Every page and attachment;
The signature, seal, and entire notarial certificate;
The notary’s stated commission and office details;
Receipts and register information;
Messages arranging the notarization;
Video, photographs, or location records;
Identification presented; and
Proof showing who was—or was not—present.

Ask the receiving institution whether a corrected or newly executed affidavit is permitted. A defective notarization can reduce a document’s evidentiary treatment to that of a private document and may require proof of due execution and authenticity. It does not automatically decide the underlying dispute, and the precise effect depends on the document, applicable law, and evidence. See G.R. No. 142309, January 30, 2009.

Suspected notarial misconduct may be reported through the appropriate judicial or lawyer-disciplinary process. Forgery, identity theft, coercion, falsification, or use of a fraudulent affidavit may also require prompt advice from a lawyer and referral to the proper law-enforcement or prosecutorial office.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A filing, appeal, registration, protest, or court deadline is near;
The affidavit will support or oppose a criminal complaint;
You are being asked to admit liability, ownership, parentage, debt, or wrongdoing;
Real property, inheritance, corporate authority, immigration status, or a large financial interest is involved;
Someone asks you to sign a false, incomplete, backdated, or pre-notarized document;
A signature, seal, ID, or notarial entry appears forged;
The affiant did not personally appear;
The affiant was pressured, deceived, incapacitated, or unable to understand the document;
A foreign-executed document has been rejected;
A court or agency has questioned the affidavit’s validity; or
You need to withdraw, correct, explain, or contradict an affidavit already submitted.

Do not “fix” a filed affidavit by changing the existing copy. Corrections may require a new affidavit, supplemental affidavit, formal motion, or other procedure appropriate to the proceeding.

Consequences of false statements

Knowingly making a material false statement under oath can result in criminal liability when the legal elements are present. Republic Act No. 11594 amended Article 183 of the Revised Penal Code and increased the penalty for perjury to prisión mayor in its minimum period, with additional consequences for a public officer or employee. Liability is not established merely because a statement is disputed or later shown to be mistaken; the prosecution must prove the statutory elements, including a knowing and willful falsehood on a material matter.

Read the current text of Republic Act No. 11594. False documents or signatures may also implicate other criminal, civil, administrative, or professional rules depending on the facts.

Frequently asked questions

Can I prepare my own affidavit?

Yes, unless a particular proceeding requires preparation or supervision by a lawyer. However, using the wrong facts, form, certificate, or attachments can cause rejection or legal harm. Obtain legal assistance when rights, liability, property, criminal allegations, or court deadlines are involved.

Must every affidavit be notarized?

An affidavit is ordinarily sworn before a person authorized to administer oaths. Whether a specific submission must be notarized—and who may administer the oath—depends on the governing law, rule, or receiving institution. Some official procedures use declarations or certifications instead.

Can I sign the affidavit at home?

For a traditional paper jurat, no. The affiant must sign in the notary’s presence. If valid electronic notarization is available and accepted, signing must occur through the prescribed electronic process in the Electronic Notary Public’s full view.

Is one government ID enough?

One current official ID bearing both photograph and signature can satisfy the documentary definition, but the notary may reasonably require additional proof where identity, name, authority, or document authenticity remains uncertain.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity under the current traditional notarial standard.

Can a relative have my affidavit notarized for me?

No. The affiant must personally appear, be identified, sign as required, and take the oath or affirmation.

Can several people sign one affidavit?

Yes, if appropriate, but every affiant must personally comply with the identification, signing, and oath requirements. Their statements and responsibilities should be clear.

Does notarization prove that all statements are true?

No. Notarization confirms the notarial acts recorded in the certificate. The facts may still be challenged, and the affidavit’s admissibility and weight depend on the applicable rules and evidence.

Does a notarized document expire?

Notarization itself does not create a universal expiration period. The receiving institution may require a recently executed affidavit, and the facts stated may become outdated. Check the specific rule or checklist.

Can a notarized affidavit be corrected?

Minor errors should be corrected before notarization. A material error discovered afterward ordinarily calls for a properly executed new or supplemental affidavit, not an informal alteration of the notarized original. If the document has already been filed, obtain advice before submitting a correction.

Is remote notarization available anywhere abroad?

Not under the Philippine rules as a general matter. A principal abroad must satisfy the limited extraterritorial conditions, including being on the premises of a Philippine embassy, consular office, or honorary-consul office during the electronic notarial act. Conventional consular or apostille procedures may be more appropriate.
