Quick answer

An affidavit is a written statement of facts made voluntarily under oath or affirmation. For an ordinary paper affidavit in the Philippines, the affiant must generally:

state truthful facts based on personal knowledge;
present the completed affidavit to a duly commissioned notary public;
personally appear before the notary;
prove identity through competent evidence of identity;
sign the affidavit in the notary’s presence; and
take an oath or affirmation that the statements are true.

The notary then completes and signs the jurat, affixes the official seal, and records the act in the notarial register. Signing at home and merely sending the document and an ID to a notary is not valid conventional notarization.

Different affidavits may have additional requirements imposed by the court, government agency, bank, school, registry, or other receiving institution. Always obtain that institution’s current form and checklist before preparing the document.

What an affidavit should contain

There is no single format for every Philippine affidavit. An ordinary affidavit commonly contains:

the title identifying its purpose;
the affiant’s full name, nationality, civil status, age or confirmation of legal age, and address, when relevant;
a statement that the affiant is executing the affidavit voluntarily;
numbered paragraphs setting out the material facts;
identification of relevant documents attached as annexes;
the purpose for which the affidavit is executed;
the affiant’s signature over the printed name;
the place and date of execution; and
a proper jurat completed by an authorized notary or other officer authorized by law to administer oaths.

Use the exact name appearing on the affiant’s valid identification unless a difference is specifically explained. If the affidavit concerns a transaction, incident, account, property, or official record, include the identifying details needed to distinguish it from others.

Write only facts the affiant actually knows. If information came from another person or document, identify the source rather than presenting it as firsthand knowledge. Conclusions, accusations, estimates, and legal labels should not be stated as established facts without an adequate basis.

A jurat is normally required for an affidavit

A jurat is the proper notarial act for a sworn affidavit. Under the 2004 Rules on Notarial Practice, a jurat requires the affiant, on a single occasion, to:

appear personally before the notary;
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.

A jurat is different from an acknowledgment. In an acknowledgment, the signatory acknowledges before the notary that the signature is voluntarily affixed for the purposes stated in the document. Acknowledgments are commonly used for contracts, deeds, powers of attorney, and similar instruments. An affidavit, by contrast, is sworn to and ordinarily requires a jurat.

Using an acknowledgment clause where a jurat is required—or simply placing the words “subscribed and sworn”—does not excuse failure to administer the oath and observe the other requirements.

Personal appearance is mandatory for conventional notarization

For traditional paper notarization, the affiant must be physically present before the notary at the time of notarization. The notary may not lawfully notarize an affidavit solely because:

the affiant previously signed it;
the affiant is personally known to the lawyer;
someone else brings the affidavit and the affiant’s ID;
the affiant appears through an ordinary phone or video call;
a secretary or staff member verifies the affiant; or
the affiant has signed other documents before the same notary.

Personal appearance allows the notary to verify identity, witness the signing, administer the oath, assess whether the affiant appears willing and aware, and make the required notarial record.

A notary must refuse the act when the affiant is absent, cannot be properly identified, appears not to understand the document, appears to be acting under duress, or the transaction is unlawful or improper.

What identification is acceptable

Under the Supreme Court’s 2008 amendment to the Rules, competent evidence of identity may consist of at least one current identification document issued by an official agency bearing the holder’s photograph and signature. The amended rule provides examples that include a passport, driver’s license, PRC ID, NBI clearance, police clearance, voter’s ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen card, government-office ID, and other qualifying government-issued identification.

Because particular IDs may be discontinued, redesigned, or rejected when expired or unverifiable, ask the notary in advance what current government-issued ID will be accepted. Bring the original, not merely a photograph or photocopy.

If the affiant lacks qualifying identification, the Rules provide a limited alternative involving two credible witnesses who:

are unaffected by the document or transaction;
personally know both the affiant and the notary; and
themselves present competent evidence of identity.

This is not satisfied by bringing any two acquaintances. The specific requirements must all be met.

The Supreme Court’s 2008 amendment on competent evidence of identity should be consulted for the controlling formulation.

Sign only in front of the notary

For a jurat, the affiant must sign in the notary’s presence. If the affidavit has already been signed, the notary may require a fresh unsigned copy or require the affiant to sign again in the notary’s presence, depending on the circumstances and the receiving institution’s requirements.

Do not leave blanks in the affidavit. Dates, names, amounts, property descriptions, account numbers, and other material particulars should be completed before notarization. Unused spaces should be addressed appropriately so information cannot be inserted afterward.

Never ask a notary to backdate an affidavit or certify that someone appeared on a date when no appearance occurred. The date in the notarial certificate must reflect the actual notarial act.

The affiant must understand the document

The affiant should read and understand the entire affidavit, including its attachments, before signing. If it is written in a language the affiant does not understand, obtain an accurate translation or use a language the affiant understands, subject to the requirements of the receiving institution.

The notary should not proceed if there is reason to believe the affiant does not understand the nature or consequences of the transaction. Additional safeguards may be necessary where the affiant has difficulty reading, hearing, speaking, signing, or communicating.

A person who cannot write may sometimes use a mark or another legally acceptable signing method, but this requires careful compliance with the applicable notarial rules and any special requirements of the receiving office. Arrange the notarization in advance rather than assuming that a thumbmark alone will always be accepted.

Notarization does not prove that every statement is true

Notarization establishes that the prescribed notarial act was performed. It does not make false statements true, validate an illegal transaction, prove ownership, cure a forged signature, or replace evidence required by law.

The affiant remains responsible for the affidavit’s contents. Deliberately making a material false statement under oath may result in prosecution for perjury or another applicable offense. False accusations may also create civil, criminal, procedural, or administrative consequences depending on the circumstances.

A notary is not automatically certifying the truth of every factual allegation. The notary certifies the matters covered by the jurat, including personal appearance, identification, signing in the notary’s presence, and administration of the oath.

Not every affidavit is sufficient for every purpose

The receiving institution may prescribe a specific affidavit, form, number of witnesses, attachments, filing method, or validity period. Examples include:

affidavits of loss for IDs, certificates, checks, or official documents;
affidavits of discrepancy or one-and-the-same-person;
affidavits of support or consent;
affidavits concerning delayed registration of civil-status records;
affidavits required for land registration, estate settlement, or tax processing;
complaints and counter-affidavits filed with prosecutors or agencies; and
judicial affidavits used as testimony in court.

A generic affidavit may be rejected even if properly notarized when it does not contain the facts or attachments required for the particular procedure.

Notarization and acceptance are separate questions. Confirm the prescribed form, permitted signing method, required annexes, number of originals, and filing deadline with the receiving office.

Judicial affidavits have special requirements

A judicial affidavit intended to replace a witness’s direct testimony is governed by the Judicial Affidavit Rule, A.M. No. 12-8-8-SC. It is not merely an ordinary narrative affidavit.

Among other matters, a judicial affidavit must generally contain:

the witness’s identifying and occupational information;
the lawyer’s name and address and the place of examination;
consecutively numbered questions and answers;
facts showing how the witness acquired personal knowledge;
identification and authentication of attached evidence;
the witness’s signature;
a jurat; and
the examining lawyer’s sworn attestation required by the Rule.

The Rule also imposes filing and service deadlines. As a general rule, the judicial affidavits and exhibits must be filed and served no later than five days before the relevant pretrial, preliminary conference, or scheduled hearing. The application of the Rule, available relief for late submission, and consequences of noncompliance depend on the proceeding. Coordinate with counsel and follow the particular court’s orders.

Electronic and remote notarization

The Supreme Court promulgated the Rules on Electronic Notarization, A.M. No. 24-10-14-SC, covering electronic documents through:

in-person electronic notarization, where the principal physically appears before an electronic notary; and
remote electronic notarization, where the required appearance occurs through synchronous audio-video communication using an accredited Electronic Notarization Facility.

Remote electronic notarization is not the same as emailing a scanned affidavit and joining an ordinary video call. The electronic notary, electronic document, identity verification, electronic signatures, electronic seal, recording, geolocation, notarial book, and facility must comply with the Rules.

The prior pandemic-era interim rules on remote notarization of paper documents were repealed by the 2025 Rules. Anyone offering remote notarization should therefore be asked to identify the accredited facility and the notary’s applicable electronic commission.

The electronic rules do not govern wills. Documents subject to special execution requirements should be reviewed separately. Availability of accredited facilities and acceptance of electronically notarized documents may also vary in practice, so confirm both with the provider and the receiving institution.

Where conventional notarization may take place

A notary’s authority is territorial. Conventional notarization must ordinarily be performed within the territorial jurisdiction covered by the notarial commission and at the notary’s regular place of work or business.

The Rules recognize limited circumstances in which a notarial act may be performed at another location within the same territorial jurisdiction, such as particular public functions or situations involving a person’s illness or other inability to travel. These exceptions do not give a notary nationwide authority.

Before proceeding, verify the notary’s identity, current commission, territorial jurisdiction, office address, and commission details. A lawyer is not authorized to notarize merely by being a member of the Philippine Bar; a current notarial commission is required.

If the affidavit will be used abroad

Ask the foreign recipient exactly what it requires. Depending on the destination and intended use, the document may need:

notarization in the Philippines;
authentication or Apostille by the Department of Foreign Affairs;
notarization or acknowledgment before a Philippine embassy or consulate;
certification by another competent foreign authority;
translation; or
additional legalization where the destination does not accept an Apostille.

An Apostille authenticates the origin of the public document or the authority and signature of the public official. It does not certify that the factual allegations in the affidavit are true.

Do not obtain an Apostille until the affidavit has been executed in the form required by the foreign recipient. Consult the DFA Authentication Services and the relevant embassy or consulate for the current appointment, documentary, and submission rules.

Practical steps before notarization

Ask the receiving institution for its current requirements. Obtain its prescribed form if one exists.
Prepare a complete and accurate draft. Use numbered paragraphs and identify relevant dates, persons, places, and documents.
Check every statement. Remove speculation and distinguish personal knowledge from information obtained elsewhere.
Prepare the attachments. Label annexes consistently and bring originals when verification may be required.
Keep the document unsigned. Sign it only when the notary instructs you to do so.
Bring an original current government-issued ID. Confirm acceptability with the notary beforehand.
Appear personally. For remote electronic notarization, use only the procedure and facility authorized by the current Rules.
Review the completed jurat. Check the date, place, notary’s name, commission details, document number, page number, book number, and series.
Obtain the required number of originals or certified copies. Ask the recipient whether photocopies will be accepted.
Keep a secure copy. Preserve the final notarized affidavit and all annexes exactly as submitted.

Evidence to preserve

Keep copies or originals, as appropriate, of:

the unsigned and final signed versions;
the complete notarized affidavit, including the jurat;
every annex referenced in the affidavit;
the ID presented for notarization, stored securely;
filing receipts, acknowledgment emails, registry receipts, and tracking records;
the receiving institution’s form and written instructions;
communications showing when and why the affidavit was requested;
appointment or transaction records for electronic notarization; and
evidence showing the factual basis for each material statement.

If fraud or irregular notarization is suspected, preserve the questioned original, envelopes, electronic files, metadata, messages, payment records, and any certification obtained from the Office of the Clerk of Court concerning the notarial entry. Avoid writing on or altering the original.

Common mistakes to avoid

Signing before meeting the notary for a jurat.
Sending the affidavit and ID through another person.
Using an expired, altered, or nonqualifying ID.
Leaving blanks that can be filled in later.
Backdating the affidavit or jurat.
Copying a template that does not fit the facts.
Stating rumors or assumptions as personal knowledge.
Failing to attach documents mentioned in the affidavit.
Confusing a jurat with an acknowledgment.
Assuming notarization guarantees acceptance by an agency or court.
Using ordinary video conferencing as a substitute for compliant electronic notarization.
Treating an affidavit as a substitute for a deed, contract, court pleading, or other instrument required by law.
Signing a document written in a language the affiant does not understand.
Altering the affidavit after notarization without executing and notarizing a corrected document.

When legal help is urgent

Consult a Philippine lawyer promptly if:

the affidavit will be used in a criminal, civil, labor, family, immigration, tax, land, or administrative case;
a prosecutor, court, regulator, or disciplinary body has imposed a filing deadline;
the affidavit admits liability, wrongdoing, receipt of money, ownership, parentage, or waiver of rights;
another person is pressuring the affiant to sign facts that are inaccurate or incomplete;
the affidavit concerns disputed land, inheritance, corporate authority, or a large financial transaction;
an affidavit or notarized instrument appears forged, fabricated, backdated, or altered;
the named affiant denies appearing before the notary;
the notarial details do not correspond with the notary’s official records;
the affidavit will be used abroad and the foreign authority’s requirements are unclear; or
a previously filed affidavit contains a material error.

Do not try to “correct” a material falsehood simply by changing a photocopy. Counsel can determine whether a corrected affidavit, supplemental affidavit, formal withdrawal, manifestation, or other filing is necessary.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily sworn before a notary or another officer authorized by law to administer oaths. Some procedures recognize verified statements, certifications, or declarations under their own rules, but these should not be assumed to replace a sworn affidavit. Follow the governing law and the recipient’s requirements.

Can I notarize an affidavit without appearing personally?

Not through conventional paper notarization. Remote appearance is possible only through compliant electronic notarization under the 2025 Rules, not through an informal video call or exchange of scanned documents.

Can I use a barangay ID or community tax certificate?

Do not assume either will be sufficient. The controlling test is whether the evidence satisfies the Supreme Court’s current definition of competent evidence of identity. Confirm acceptability with the notary and bring a qualifying current government-issued photo-and-signature ID whenever possible.

Can the notary prepare the affidavit?

A notary who is also a lawyer may separately provide legal drafting services, subject to professional and ethical rules. Drafting and notarization are distinct acts. The affiant must still review the document, confirm its truth, personally appear, sign as required, and take the oath.

Does a notarized affidavit automatically win a case?

No. It may still be challenged for relevance, admissibility, hearsay, lack of personal knowledge, inconsistency, credibility, falsity, improper execution, or other defects. In court proceedings, the witness may still have to appear for cross-examination.

Is a photocopy of a notarized affidavit valid?

A receiving institution may accept a copy for some purposes and require an original or certified copy for others. Confirm its rule. Never represent an ordinary photocopy as an original or certified copy.

Can an affidavit be changed after notarization?

Do not insert, delete, or replace material information after notarization. Prepare a corrected or supplemental affidavit and have it properly executed and notarized. If the original has already been filed, obtain legal advice about the proper corrective filing.

How long is a notarized affidavit valid?

There is no universal expiration period for every affidavit. Its usefulness depends on its purpose, the date-sensitive nature of the facts, and the receiving institution’s rules. Some offices require a recently executed affidavit even when the underlying facts have not changed.

Does notarization make an invalid document valid?

No. Notarization does not cure illegality, incapacity, lack of authority, forgery, an invalid waiver, failure to obtain required consent, or noncompliance with special statutory formalities.
