Quick answer

A Philippine affidavit must contain a complete and truthful statement of facts, be signed by the affiant, and be sworn to or affirmed before a notary public or another officer legally authorized to administer oaths. For a paper affidavit, the affiant ordinarily must personally appear before the notary, present acceptable proof of identity, sign in the notary’s presence, and take an oath or affirmation. The notary then completes the jurat, signs it, affixes the official seal, and records the act in the notarial register.

Do not sign a paper affidavit in advance unless the notary instructs you to do so. Do not use a notary who offers to stamp a document without seeing the affiant. Remote notarization is possible only through the regulated electronic-notarization system—not through an ordinary video call, emailed signature page, or couriered paper document.

The receiving court, agency, bank, school, employer, embassy, or private institution may require a particular form, supporting documents, number of copies, or submission deadline. Its current checklist should be obtained before drafting or notarizing anything.

Affidavit, jurat, and acknowledgment are different

An affidavit is a written statement made under oath or solemn affirmation. It normally uses a jurat, not an acknowledgment.

Notarial act	What the signer does
Jurat	Personally appears, is identified, signs in the notary’s presence, and swears or affirms that the statements are true. This is the usual act for affidavits.
Acknowledgment	Personally appears, is identified, and declares that an existing signature was voluntarily affixed and that the document is the signer’s free act and deed. Commonly used for contracts, deeds, and powers of attorney.
Signature witnessing	Signs in the notary’s presence, without necessarily swearing to the truth of the document’s contents.

A document labeled “Affidavit” but bearing only an acknowledgment may not satisfy a requirement for a sworn statement. Conversely, placing “under oath” in the text does not replace the administration of an oath and completion of a proper jurat.

What a paper affidavit should contain

The exact form depends on its purpose, but a sound affidavit usually includes:

Venue. The city or province shown above the affidavit should reflect where the oath is actually administered—not necessarily the affiant’s residence.
Affiant’s identifying details. Use the full legal name appearing on the identification document. Include age, citizenship, civil status, address, occupation, or representative capacity only when relevant or required.
Numbered factual statements. State facts clearly, chronologically, and from personal knowledge. Distinguish what the affiant personally saw, did, received, or knows from information learned from someone else.
Purpose. Identify why the affidavit is being executed, such as reporting a loss, explaining a discrepancy, supporting a complaint, or complying with an agency requirement.
Attachments. Refer to supporting records accurately and label them consistently. All material pages and annexes should be complete before notarization.
Affiant’s signature or permitted mark. For a jurat, this is made in the notary’s presence. Special safeguards apply when a person is physically unable to sign or make a mark.
Jurat. This normally begins with “Subscribed and sworn to before me,” followed by the date and place, the affiant’s identification details, and the notary’s signature, seal, commission information, and notarial-register references.

Do not leave material blanks. Use “N/A” where appropriate, or have non-applicable spaces cancelled before signing. Do not add pages, change facts, replace annexes, or alter dates after notarization; a material change generally calls for a corrected document and a new notarial act.

Identification requirements

If the affiant is not personally known to the notary, the traditional rules require at least one current identification document issued by an official agency and bearing both the person’s photograph and signature. Examples in the rules include passports, driver’s licences, PRC IDs, SSS or GSIS cards, senior-citizen cards, and comparable official identification.

A community tax certificate or cedula is not competent evidence of identity for this purpose. A birth certificate also does not, by itself, meet the photo-and-signature requirement.

Bring:

The original current ID, not merely a screenshot or photocopy;
A backup government-issued photo-and-signature ID, especially if the first card lacks a visible signature or has inconsistent details;
Any photocopies requested by the notary;
Supporting records and all pages of the affidavit; and
Proof of authority when signing in a representative capacity.

Although the rules establish a baseline of one qualifying ID, a notary may reasonably request additional proof when names, photographs, signatures, addresses, or other details are unclear. A receiving institution may also impose its own documentary checklist.

When no qualifying ID is available, the rules provide a limited credible-witness procedure:

One credible witness who is personally known to the notary, personally knows the affiant, and is not involved in the document or transaction; or
Two credible witnesses who personally know the affiant, are not involved in the document or transaction, and present their own documentary identification.

Arrange this with the notary beforehand. The witnesses must take the required oath and sign the notarial register.

What must happen before the notary

For a traditional paper affidavit:

The affiant personally appears before a currently commissioned notary public within the notary’s territorial jurisdiction.
The notary receives the complete affidavit and checks the affiant’s identity.
The affiant signs in the notary’s presence.
The notary administers an oath or affirmation. The affiant must expressly confirm the truth of the statements.
The affiant signs or places the required mark in the notarial register.
The notary completes the jurat, signs it, affixes the official seal, and supplies the document, page, book, and series references.

Appearance before only a secretary, runner, liaison, or office assistant is insufficient. Leaving an already signed document and an ID for later stamping is not valid personal appearance.

A notary should refuse a blank or incomplete document, a transaction in which the notary is disqualified or has a prohibited interest, or an act involving a person whose identity, willingness, understanding, or authority cannot be satisfactorily established. A notary is also disqualified when the principal is the notary’s spouse, common-law partner, ancestor, descendant, or relative within the fourth civil degree under the rules.

Paper and electronic notarization

The 2025 Rules on Electronic Notarization supplement rather than replace traditional notarization.

Mode	Document and appearance requirements
Traditional notarization	Paper document with handwritten signature or mark; physical appearance under the 2004 Rules.
In-Person Electronic Notarization	Electronic document and electronic signature processed through an accredited Electronic Notarization Facility, with the principal physically present before an Electronic Notary Public.
Remote Electronic Notarization	Electronic document processed through an accredited facility, with synchronous audio-video appearance before an Electronic Notary Public and electronic identity verification.

Electronic notarization does not cover paper documents bearing wet signatures. It also does not apply to wills or deposition taking. For a remote electronic jurat, the oath, identity verification, signing, recording, and electronic notarial certificate must all be completed through the regulated facility.

An ordinary Zoom, Messenger, or video call followed by the stamping of a paper affidavit is not a substitute. Verify both the notary and the facility through the Supreme Court’s eNotary Services page and directory.

As a general rule, remote electronic notarization is performed while the principal is in the Philippines. A principal abroad may use the limited extraterritorial procedure only while physically within a Philippine embassy, consular office, or honorary consul’s office and after the prescribed location confirmation.

The electronic copy required after paper notarization

Under the 2025 amendments to the 2004 Notarial Rules, a notary must transmit an electronic copy to each signatory, at no additional cost, through email or a mutually agreed file-sharing method within the prescribed five-day period. A signatory may waive transmission, but the waiver also affects the right to object to the completeness of the electronic reproduction.

Before leaving:

Confirm the email address or agreed delivery method;
Keep the paper original or issued counterpart;
Compare the electronic copy promptly with the paper document;
Check every page, signature, annex, date, and notarial detail; and
Notify the notary immediately in writing if a material discrepancy affects any party’s rights.

No separate fee may be charged for digitizing, transmitting, storing, or processing this required copy.

Does notarization prove that every statement is true?

No. Notarization primarily establishes the notarial act: the signer’s appearance and identity, the administration of the oath or acknowledgment, and the execution recorded by the notary. It does not independently verify every factual allegation or guarantee that the document is legally sufficient for its intended purpose.

Proper notarization can give a document the evidentiary treatment accorded to public documents. Defective notarization may cause it to lose that presumption and be treated as a private document requiring additional proof. When a valid oath is an express filing requirement, a defective jurat may also result in rejection or other procedural consequences. The ultimate effect depends on the governing law, the defect, and the proceeding.

Notarization likewise does not:

Correct a PSA civil-registry record;
Transfer or register property by itself;
Replace registration with the Registry of Deeds or another agency;
Establish that a contract is fair or enforceable;
Supply missing legal authority; or
Replace an Apostille or consular legalization when the document will be used abroad.

Deadlines and validity

There is no universal expiration period for all affidavits. An affidavit records facts sworn to on a particular date, but the receiving institution may require one executed within a specified recent period. Facts may also become outdated.

The filing deadline depends on the transaction or proceeding. A subpoena, court order, agency rule, bid document, immigration checklist, or application form may impose a much shorter period than the affidavit itself suggests.

For example, the Judicial Affidavit Rule generally requires covered judicial affidavits and exhibits to be filed and served no later than five days before the relevant pre-trial, preliminary conference, or scheduled hearing. That rule applies only within its defined scope and contains exceptions and sanctions. Do not assume that the same period applies to an ordinary affidavit.

Documents executed or used abroad

Affidavit signed abroad for use in the Philippines

Common routes include:

Personal execution before a Philippine embassy or consulate that offers notarial services; or
Notarization before a competent local notary, followed by an Apostille from the foreign country’s competent authority if that country and the Philippines use the Apostille Convention.

Where the Apostille Convention does not apply—or where a particular exception or bilateral arrangement exists—authentication or legalization may still be required. Follow the receiving Philippine office’s checklist and the instructions of the Philippine foreign-service post with jurisdiction.

Philippine affidavit for use abroad

A private document executed in the Philippines ordinarily must first be properly notarized. The DFA may then require a Certificate of Authority for a Notarial Act, issued by the appropriate court, before Apostille processing. Requirements vary by document type; verify them through the DFA’s current documentary requirements.

An Apostille authenticates the origin of the public document or notarial certification. It does not certify that the affidavit’s allegations are true or guarantee acceptance by the foreign recipient.

Practical checklist

Before notarization:

Obtain the latest form and checklist from the intended recipient.
Confirm whether a jurat, acknowledgment, witnesses, annexes, or special wording is required.
Use names and details consistent with official records.
Review every statement for accuracy and personal knowledge.
Bring the complete unsigned affidavit, all annexes, and original qualifying ID.
Make sure every required affiant and witness can personally appear.
Confirm that the notary’s commission is current and covers the place of notarization.

After notarization:

Check the date and place of execution.
Check the notary’s signature, seal, commission details, and document/page/book/series entries.
Keep the final paper copy, transmitted electronic copy, annexes, receipt, and relevant correspondence.
Submit the document through the receiving office’s authorized channel before its deadline.
Keep proof of filing or delivery.

Common mistakes to avoid

Signing a jurat before meeting the notary;
Sending only a signature page for notarization;
Using a cedula as the sole proof of identity;
Allowing a runner or office employee to “process” the affidavit without the affiant’s appearance;
Leaving material blanks or missing pages;
Using an acknowledgment when the document must be sworn;
Backdating the affidavit or notarial certificate;
Copying a template whose facts or legal statements do not fit the situation;
Including hearsay or conclusions as though personally observed;
Failing to attach records specifically required by the receiving office;
Altering the affidavit after notarization;
Assuming notarization automatically makes an invalid transaction valid; or
Paying for an informal “online notarization” that does not use an accredited facility and commissioned Electronic Notary Public.

If the notarization appears false or fraudulent

Preserve:

Every original, photocopy, scan, and electronic version;
The email transmitting the electronic copy;
Envelopes, receipts, appointment records, and payment proof;
Messages with the notary, staff, runner, or other parties;
Travel, employment, immigration, or location records showing where the alleged signer was;
Genuine signature samples and identification records; and
Any record obtained from the notary or the appropriate Clerk of Court.

A signatory may request a certified copy of the relevant notarial record, subject to the applicable rules and fees. If the signature was forged, the signer never appeared, the commission had expired, or the document differs materially from the copy retained or transmitted, consult a Philippine lawyer promptly. Depending on the circumstances, immediate notice may also be needed to the court or agency handling the document, the Executive Judge supervising the notary, the Registry of Deeds, a bank, law-enforcement authorities, or another affected institution.

Help is especially urgent when the document concerns land, an estate, a power of attorney, a waiver or settlement, a loan or mortgage, immigration, custody, criminal allegations, or a pending filing deadline.

False statements and perjury

A knowingly untruthful statement on a material matter in an affidavit made under the circumstances covered by Article 183 of the Revised Penal Code may constitute perjury. As amended by Republic Act No. 11594, the prescribed principal penalty is prisión mayor in its minimum period—six years and one day to eight years—together with the statutory fine and disqualification consequences. Public officers or employees are subject to the rule’s higher penalty treatment.

Not every mistake automatically constitutes perjury. Materiality, knowledge, the nature of the oath, the authority of the officer, and the other statutory elements must be proved. Correct an honest mistake immediately and obtain advice before attempting to withdraw, replace, or contradict an affidavit already submitted in a legal proceeding.

Frequently asked questions

Can I sign the affidavit at home?

For a paper affidavit with a jurat, the signature must be made in the notary’s presence. Bring it unsigned. Electronic signing is possible only through the compliant electronic-notarization process.

Are two government IDs always required?

The traditional rules’ baseline is at least one current official-agency ID bearing both photograph and signature. A notary or receiving institution may reasonably require additional proof.

Is a cedula enough?

No. Supreme Court decisions have repeatedly held that a community tax certificate is not competent evidence of identity under the notarial rules.

Can a relative notarize my affidavit?

Not when the notary is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

Does an affidavit expire after six months?

There is no general six-month expiration rule. The receiving office may require a recently executed affidavit, and the statements must remain accurate when the document is submitted or relied upon.

Can a defective affidavit simply be notarized again?

Usually, a corrected and complete affidavit can be executed under a new oath, but the earlier affidavit does not disappear. If it has already been filed, relied upon, or contains a material error, obtain legal advice and follow the receiving body’s procedure for correction, withdrawal, or supplemental filing.
