Quick answer

An affidavit is a written statement of facts that the affiant swears or solemnly affirms to be true before a person authorized to administer an oath. In ordinary Philippine practice, the affiant must personally appear before a duly commissioned notary public, establish identity through competent evidence, sign the affidavit in the notary’s presence, and take an oath or affirmation. The notary then completes the jurat, records the act, and affixes the required signature and seal.

There is no single format that works for every affidavit. The court, government agency, employer, bank, school, or other recipient may prescribe its own wording, attachments, filing period, number of copies, or documentary requirements. Notarization does not establish that every allegation is true, cure an unlawful transaction, or make a legally defective affidavit sufficient for its intended purpose.

What makes a document an affidavit?

A document ordinarily functions as an affidavit when it contains:

The affiant’s full name and sufficient personal details to identify the affiant;
A clear statement that the affiant is competent to testify about the matters stated;
Facts stated from the affiant’s personal knowledge, preferably in separately numbered paragraphs;
Identification of any supporting documents attached to or referred to in the affidavit;
The affiant’s signature; and
A properly completed jurat showing that the affiant personally appeared, signed the document, and swore or affirmed that its contents were true.

The exact details required depend on the affidavit’s purpose. An affidavit of loss, complaint-affidavit, affidavit of support, affidavit of discrepancy, judicial affidavit, and affidavit used for land registration are not interchangeable.

Names, dates, addresses, identification numbers, property descriptions, account numbers, and other material particulars should be checked against the supporting records before the document is signed.

A jurat is different from an acknowledgment

The correct notarial act matters.

Jurat

A jurat is normally used for an affidavit. The affiant:

Personally appears before the notary;
Signs the affidavit in the notary’s presence; and
Takes an oath or solemn affirmation that the statements are true.

The notarial certificate commonly begins with wording such as “Subscribed and sworn to before me,” but the certificate must be completed by the notary in accordance with the applicable rules.

Acknowledgment

An acknowledgment is commonly used for deeds, contracts, powers of attorney, and similar instruments. The signer personally appears and declares that the signature is voluntary and that the document is the signer’s free act and deed.

Merely placing an acknowledgment at the end of a document does not necessarily turn factual statements into sworn testimony. Conversely, attaching a jurat cannot correct substantive defects in a contract or substitute for formalities required by a particular law.

Personal appearance is generally mandatory

For conventional paper notarization, the signer must be in the notary’s physical presence at the time of the notarial act. Sending a signed affidavit through a relative, messenger, law-office employee, email, or ordinary video call is not a substitute for personal appearance.

A notary should not notarize a document if:

The supposed affiant is absent;
Someone else signed for the affiant without a legally sufficient basis;
The document contains blank or incomplete material portions;
The notary has reason to believe the signature is forged;
The affiant appears unable to understand the document;
The affiant is being compelled or is not acting voluntarily;
The transaction or act is unlawful or improper; or
The notary cannot establish the affiant’s identity.

The Supreme Court repeatedly emphasizes that notarization is not a routine stamping service. It converts a private instrument into a public document for evidentiary purposes and must therefore be performed with care.

What identification should the affiant bring?

Under the amended definition in the 2004 Rules on Notarial Practice, competent evidence of identity generally includes at least one current identification document issued by an official agency and bearing the individual’s photograph and signature.

Examples identified by the Supreme Court include a passport, driver’s license, PRC identification card, SSS card, GSIS e-card, senior-citizen card, seaman’s book, government-office identification card, and certain other official identification documents or certifications.

Practical precautions include:

Bring the original, current ID rather than only a photograph or photocopy.
Make sure the name on the affidavit corresponds with the ID.
Bring a second government-issued ID when available, particularly if one ID lacks a visible signature or contains an old name or address.
Bring records explaining a name discrepancy, such as a PSA certificate, marriage certificate, court order, or administrative correction.
Ask the notary or receiving institution in advance if it requires a specific ID.

A community tax certificate, by itself, should not be treated as sufficient competent evidence of identity under the present rules.

The rules also recognize identification through two credible witnesses under specified conditions. Each witness must be unaffected by the document and must personally know the signer. The witnesses must themselves be properly identified, and the notary must administer the required oath or affirmation. This is not simply a workaround for someone who forgot to bring an acceptable ID.

Should the affidavit be signed before visiting the notary?

Ordinarily, no. Because an affidavit requires a jurat, the affiant should sign it in the notary’s presence after the notary has verified identity and confirmed that the affiant understands the oath or affirmation.

Do not sign blank pages, incomplete affidavits, or unattached signature pages. Do not leave material blanks to be completed after notarization. If a correction is necessary, it should be made transparently before the notarial act and initialed where appropriate, or the document should be reprinted.

If several people are affiants, each must satisfy the appearance, identity, signature, and oath requirements. They need not necessarily appear together unless the document or receiving institution requires it, but the notarial certificate and entries must accurately reflect what occurred.

What should the affiant bring?

Depending on the purpose, prepare:

The complete, unsigned affidavit;
At least one acceptable current government-issued identification document, preferably two;
Original or reliable copies of the records supporting the statements;
All annexes mentioned in the affidavit;
The reference number, prescribed form, or written instructions from the recipient;
Proof of any relevant name change or discrepancy;
Enough copies for filing and personal records; and
Contact information for the receiving office if its requirements need confirmation.

For an affidavit of loss, bring available proof that the missing item existed and belonged to the affiant. For an affidavit involving property, bring the title, tax declaration, technical description, deed, or other relevant record. For a complaint-affidavit, preserve and organize the evidence supporting each alleged act, date, participant, and resulting injury.

Attachments and annexes

Every document mentioned as an annex should be identifiable and complete. Common practice is to label attachments sequentially—for example, Annex “A,” Annex “B,” and so on—and refer to each label in the affidavit.

Before signing, check that:

Every referenced annex is actually attached;
Page numbers and annex labels are consistent;
Screenshots show relevant dates, account names, URLs, or message details where available;
Photocopies are legible;
Alterations have not obscured context; and
Originals are preserved separately.

A recipient may require certified true copies, original documents, translations, authentication, or another form of verification. Notarizing the affidavit does not automatically authenticate every attachment.

The notary’s commission and territorial authority

A Philippine notary public must be a lawyer with a valid notarial commission. The commission is issued for a particular territorial jurisdiction and limited period. The notary may ordinarily perform notarial acts only within that authorized territory, subject to the applicable rules and permitted exceptions.

The notarial certificate should contain the required particulars, including the place and date of notarization, information concerning the affiant’s identity, the notary’s commission details, document and register references, signature, and official seal.

The affiant should reject a document bearing an incomplete jurat, missing notarial details, a blank notarial certificate, or information that does not match the actual appearance. When authenticity is important, the notarial commission and entry may be verified through the office of the clerk of court that supervises notaries in the relevant locality.

Electronic notarization is not an ordinary online call

The Supreme Court has adopted the Rules on Electronic Notarization and established an official electronic-notarization framework. Electronic notarization must be performed by a properly commissioned electronic notary public through the authorized system and in compliance with identity verification, electronic-signature, audiovisual, recordkeeping, and security requirements.

A document is not validly notarized merely because:

The signer and lawyer met through Zoom, Messenger, or another private video platform;
A scanned signature and image of a notarial seal were pasted into a PDF;
The signer emailed a photograph of an ID; or
A lawyer remotely watched someone sign without using the authorized procedure.

Before relying on electronic notarization, confirm that the electronic notary public is duly commissioned and that the transaction will pass through the Supreme Court’s official process. The Supreme Court maintains an eNotarization information portal and a page for commissioned electronic notaries public.

Copies and electronic transmission under the amended rules

The Supreme Court’s 2025 amendments strengthened the preservation and electronic submission of notarized documents. Among other duties, commissioned notaries must follow prescribed requirements for maintaining and transmitting electronic copies of covered documents. The official seal must remain visible in the digitized copy.

A notary must also electronically send a copy of the notarized document to each signatory within the period prescribed by the amended rules—generally within five days of completion of the notarial act or the applicable submission deadline—unless the signatory validly waives receipt. No separate charge may be imposed merely for the required digitization or transmission.

Upon receiving a copy:

Compare every page with what was signed.
Check the names, dates, annexes, signatures, seal, and notarial details.
Preserve the email and attached file.
Notify the notary promptly and in writing if a material discrepancy affects anyone’s rights.
Do not edit the notarized PDF or replace its pages.

The amendments are available in the Supreme Court’s official consolidated text of the amended notarial rules.

Affidavits executed outside the Philippines

A person abroad may execute an affidavit before a Philippine embassy or consulate that provides notarial services, subject to that post’s appointment, personal-appearance, identification, and documentary requirements.

Another possible route is execution before a competent foreign notary followed by an Apostille or other authentication required for use in the Philippines. The correct route depends on:

The country where the affidavit is executed;
Whether that country is covered by the Apostille Convention;
The type of document;
The Philippine agency or court receiving it; and
Any special procedural rule governing the matter.

An Apostille authenticates the origin of a public document; it does not prove that the affidavit’s factual allegations are true. Current documentary requirements and application procedures are published by the DFA’s Authentication Division.

Special-purpose affidavits may have additional rules

Judicial affidavits

A judicial affidavit intended to serve as a witness’s direct testimony must comply with the Judicial Affidavit Rule. It generally requires a question-and-answer format, identification of the examining lawyer, circumstances showing that the witness answered under oath, properly marked exhibits, and the lawyer’s sworn attestation. Filing deadlines and exceptions depend on the court and proceeding.

A conventional narrative affidavit should not be assumed to satisfy the Judicial Affidavit Rule.

Complaint-affidavits and counter-affidavits

Criminal complaints undergoing preliminary investigation follow procedural requirements issued under the Rules of Criminal Procedure and applicable prosecution-service rules. Submission periods can be short. The affidavit should address the elements of the alleged offense and attach supporting evidence rather than rely on conclusions or accusations alone.

Agency-prescribed affidavits

The LTO, PSA, Registry of Deeds, Bureau of Immigration, banks, insurers, schools, and other institutions may use prescribed forms or impose additional documentary requirements. Confirm the latest requirements directly with the receiving office before notarization.

Does a notarized affidavit expire?

Philippine notarial law does not impose one universal expiration period on every affidavit. However, a recipient may require a recently executed affidavit, and the statements can become inaccurate when circumstances change.

An affidavit should be updated when:

A material fact has changed;
The stated purpose or recipient has changed;
A required attachment has expired;
The receiving office imposes a recency requirement; or
The original contains a material error.

A fresh affidavit does not erase an earlier sworn statement. Material inconsistencies may require a written explanation and can affect credibility.

Legal effect—and limits—of notarization

Proper notarization gives a document the evidentiary character accorded to a public document. It supports the authenticity and due execution of the instrument without the same preliminary proof ordinarily required for a private document.

It does not automatically:

Establish the truth of every statement;
Transfer ownership when other legal requirements are absent;
Validate a forged, simulated, illegal, or void transaction;
Prove that the affiant personally perceived every fact stated;
Bind people who did not execute the document;
Replace registration, filing, approval, or publication required by law; or
Guarantee that a court or agency will accept the affidavit.

A materially defective notarization may cause the document to be treated as a private instrument and may expose the responsible parties to civil, criminal, administrative, or professional consequences.

False statements and perjury

An affidavit should never be signed merely because someone says it is “only a requirement.” Read every paragraph and correct anything that is false, misleading, speculative, or outside personal knowledge.

Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making an untruthful sworn statement about a material matter before a competent person, in a case in which the law requires an oath, may constitute perjury. Whether the elements are present depends on the exact statement, its materiality, the oath, the proceeding or legal requirement, the affiant’s knowledge, and the evidence of deliberate falsehood.

An honest mistake is not automatically perjury, but a material error should be corrected promptly through the procedure appropriate to the receiving office or case.

Evidence to preserve

Keep secure copies of:

The exact affidavit and every page signed;
All annexes in the form submitted;
The affiant’s identification used for notarization;
Receipts and appointment records;
The notary’s name, office address, commission details, and contact information;
Emails transmitting the notarized copy;
Filing receipts, acknowledgment emails, docket numbers, and tracking records;
Drafts or messages showing who supplied the disputed information; and
Originals of documents, devices, messages, photographs, or recordings supporting the affidavit.

Preserve original electronic files and metadata where litigation or a criminal complaint is possible. Avoid relying solely on cropped screenshots or forwarded copies.

Common mistakes to avoid

Signing before meeting the notary when a jurat is required;
Sending another person to obtain notarization;
Using an expired or insufficient ID;
Leaving blanks or unattached signature pages;
Copying a generic online affidavit without checking the recipient’s form;
Confusing a jurat with an acknowledgment;
Stating legal conclusions instead of specific facts;
Including facts based only on rumor without identifying the source;
Failing to attach documents mentioned in the affidavit;
Using inconsistent names, dates, addresses, or property descriptions;
Altering the document after notarization;
Assuming notarization alone makes the document legally sufficient; and
Agreeing to backdate, predate, or falsely describe the affiant’s appearance.

When legal help is urgent

Seek prompt legal advice when:

An affidavit will be filed in court, with a prosecutor, or in an administrative case;
A deadline for a complaint-affidavit, counter-affidavit, judicial affidavit, appeal, or response is approaching;
The document concerns ownership of land, inheritance, corporate authority, custody, support, immigration status, or a large financial obligation;
Someone is pressuring the affiant to sign statements that are inaccurate or not understood;
A signature appears forged or the affiant never appeared before the stated notary;
Pages, annexes, or material terms were changed after signing;
The affidavit contradicts an earlier sworn statement;
The person who signed lacked capacity or was under coercion;
The notary’s commission or register entry cannot be verified; or
The affidavit has already caused arrest, loss of property, denial of benefits, or another serious consequence.

Do not “correct” a notarized affidavit by erasing text, replacing pages, or editing the digital file. Obtain advice on whether to execute a supplemental, corrective, or new affidavit and how to notify the receiving authority.

Frequently asked questions

Can a non-lawyer prepare an affidavit?

An affiant may write a factual statement, but only a person authorized by law may perform the notarial act. Legal assistance is advisable when the affidavit affects a case, property, status, liability, or another person’s rights.

Can any lawyer notarize a document?

No. The lawyer must hold a valid notarial commission and act within the authority and territorial limits of that commission. Electronic notarization additionally requires the proper electronic-notary commission and authorized system.

Is one government ID enough?

The rules generally recognize at least one current official identification document bearing the holder’s photograph and signature. A particular notary or receiving institution may reasonably request additional proof where the ID is unclear, incomplete, damaged, inconsistent, or insufficient for the transaction.

Can an affidavit be notarized without the affiant?

No, not through conventional paper notarization. An authorized electronic-notarization procedure is also not a license to skip the required appearance and identity safeguards.

Is a barangay certificate always sufficient identification?

No. Sufficiency depends on whether the document meets the requirements for competent evidence of identity and on the circumstances of the notarial act. Bring stronger government-issued photo-and-signature identification when available.

Can a notary notarize a photocopy?

A notary may perform only the notarial act authorized by the rules and supported by the document and appearance presented. Notarization of an affidavit referring to a photocopy does not certify that the photocopy is a genuine copy of the original unless an authorized certification procedure has separately been performed.

Can someone use an affidavit instead of appearing as a witness?

Not automatically. Courts generally require testimony and cross-examination under applicable procedural rules. A judicial affidavit may substitute for direct testimony only when the Judicial Affidavit Rule applies and its requirements are satisfied.

Does notarization make a contract valid?

Not necessarily. Some contracts are valid without notarization, while others must satisfy additional form, authority, consent, registration, or substantive requirements. Notarization cannot validate an illegal or void agreement.
