Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. For a paper affidavit to be properly notarized in the Philippines, the affiant generally must:

Use a complete document with no unexplained blanks.
Personally appear before a duly commissioned notary public.
Establish identity through personal knowledge or competent evidence of identity.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that the statements are true.
Receive a completed jurat bearing the notary’s signature, seal, commission details, and notarial-register information.

A photocopied ID sent through a messenger, an emailed signature, or an ordinary video call is not enough for traditional paper notarization. Electronic and remote notarization are possible only under the separate Supreme Court rules for electronic documents and through the prescribed electronic-notarization system.

Notarization does not prove that every statement in an affidavit is true, correct a legally defective document, or guarantee that the receiving court or agency will accept it.

What a proper affidavit should contain

There is no single form for every Philippine affidavit. The contents depend on its purpose, but a reliable affidavit normally includes:

The affiant’s complete name and relevant personal details, such as age, citizenship, civil status, and address.
A clear statement that the affiant is executing the affidavit voluntarily and is competent to state the facts.
Numbered paragraphs containing specific facts, preferably based on personal knowledge.
Exact names, dates, places, amounts, document numbers, and other material details.
The purpose for which the affidavit is being executed.
Properly identified attachments, if any.
The affiant’s signature or permitted mark.
A jurat completed by the notary or other officer authorized to administer the oath.

Avoid sweeping conclusions such as “the respondent committed fraud” unless the affidavit also states the concrete facts supporting that assertion. When information comes from records rather than personal observation, identify the record and attach or preserve it when appropriate.

The receiving office may prescribe its own form or require additional statements. Affidavits involving loss, support, guardianship, travel consent, corporate authority, civil-registry corrections, tax matters, immigration, land, or court proceedings should be checked against the rules of the specific agency or proceeding.

Jurat versus acknowledgment

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

Notarial act	What the signer does
Jurat	Signs in the notary’s presence and takes an oath or affirmation that the document’s contents are true.
Acknowledgment	Personally appears and declares that the signer voluntarily executed an instrument, including in an authorized representative capacity when applicable.

An acknowledgment may be appropriate for contracts, deeds, powers of attorney, and similar instruments. Replacing an affidavit’s jurat with an acknowledgment can be a material defect because the signer may not have sworn to the truth of the statements.

Personal appearance is the general rule for paper affidavits

Under the 2004 Rules on Notarial Practice, a notary must not notarize a paper document when the signatory is not personally present at the time of notarization.

This means the notary should not:

Notarize a document brought only by a relative, employee, liaison, or fixer.
Rely only on a photocopy or image of the affiant’s ID.
Notarize a signature based solely on a telephone call or ordinary video call.
Allow the affiant to sign elsewhere when the required act is a jurat.
Backdate the jurat or state that the affiant appeared on a date when no appearance occurred.

A paper notary ordinarily acts at the notary’s regular place of work and within the territorial jurisdiction of the commissioning court. The rules permit limited off-site notarization within that jurisdiction in specified settings, including certain public functions, hospitals where a party is confined, and places where a party is detained.

Acceptable proof of identity

The affiant must be personally known to the notary or identified through competent evidence of identity. The current paper-notarization rule generally calls for at least one current identification document issued by an official agency and bearing both the holder’s photograph and signature. Common examples include a current passport, driver’s license, or PRC identification card.

Bring the original ID. A notary may request a photocopy for the notarial record or require another current ID if the photograph, signature, name, or validity cannot be reliably checked. Community Tax Certificates or cedulas are not competent evidence of identity under the amended rule.

When the affiant lacks qualifying identification, the rules provide a limited credible-witness route:

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

Credible witnesses are not a convenient substitute for an available valid ID. They assume responsibility under oath for identifying the affiant.

The controlling definition appears in the Supreme Court’s 2008 amendment to the identification rule.

What the notary must check

A notary is not merely a signature-and-seal service. Before notarizing, the notary should determine that:

The person appearing is the actual affiant.
The affiant understands the affidavit and the consequences of signing it.
The affiant is acting freely and voluntarily.
The document is complete and does not contain prohibited blank spaces.
The requested act is lawful and proper.
The notary is authorized to act in the place and on the date shown.
The notary is not disqualified by personal interest or prohibited relationship.

A notary is disqualified when, among other cases, the notary is a party to the document, will receive a prohibited direct or indirect benefit from it, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative within the degree prohibited by the rules.

The notary should refuse the act when there is good reason to believe that the transaction is unlawful or immoral, the signer does not understand its consequences, or the signer is acting under coercion.

Signing by thumbmark or for a person unable to sign

The notarial rules provide special safeguards when a person signs by thumbmark or another mark, or cannot sign or make a mark. These procedures generally require two disinterested and unaffected witnesses, prescribed notarial wording, and signing in the notary’s presence.

Do not improvise this process. Tell the notary in advance about the person’s physical condition, literacy, language needs, or inability to sign. If capacity, coercion, inheritance, property, or authority may later be disputed, obtain legal advice before execution and consider preserving medical or other independent evidence of capacity.

Step-by-step preparation checklist

1. Confirm the receiving office’s requirements

Ask for the exact name of the required affidavit, prescribed form, number of originals, supporting documents, acceptable language, and filing deadline. Determine whether the office requires a recently executed affidavit, wet-ink original, electronic document, apostille, or additional certification.

2. Draft only facts that can be supported

Prepare a clear chronology. Separate personal knowledge from information obtained from documents or other people. Do not sign an affidavit containing facts you have not verified.

3. Assemble the supporting evidence

Depending on the subject, preserve and organize:

Contracts, receipts, invoices, bank records, and proof of payment.
Messages, emails, call logs, and screenshots with dates and account details.
Photographs, videos, and original electronic files.
Police, medical, employment, school, property, or government records.
Delivery records and proof that notices were sent or received.
Names and contact details of people with direct knowledge.
Prior versions of the affidavit and the instructions or form issued by the receiving office.

Identify attachments consistently—for example, “Annex A”—and ensure the affidavit accurately describes them.

4. Bring the complete unsigned affidavit and original ID

For a jurat, sign only when instructed by the notary. Bring all pages and attachments, together with the original current ID and any proof of representative authority.

5. Appear and take the oath

Read the entire document before signing. Correct errors openly before notarization. Do not permit pages to be replaced or material changes to be made afterward.

6. Inspect the completed notarization

Check that the jurat states the correct date and place and that the notarial certificate contains the notary’s signature, seal, commission information, and document, page, book, and series entries where applicable.

7. Preserve your records

Keep:

A complete copy of the notarized affidavit and all annexes.
The official receipt or proof of payment.
Proof of filing or delivery.
The name, office address, and commission details of the notary.
The editable draft and original supporting records.

Under the 2025 amendments to the paper-notarization rules, notaries have additional electronic recordkeeping and transmission duties. When mutually agreed, an electronic copy may be transmitted without an added charge for digitizing, transmitting, or processing it.

Electronic and remote notarization

The Supreme Court’s 2025 Rules on Electronic Notarization supplement rather than replace traditional notarization. They apply to electronic documents signed electronically. Paper documents bearing handwritten signatures or marks remain governed by the 2004 Rules.

The electronic rules recognize:

In-person electronic notarization: The principal and witnesses physically appear before an Electronic Notary Public, but the document and signatures are electronic.
Remote electronic notarization: Appearance occurs through the audiovisual facilities of an accredited Electronic Notarization Facility.
A combination of the two modes: Appropriate when some participants appear physically and others remotely, subject to the rules.

A scanned paper bearing a handwritten signature does not automatically become a properly electronically notarized document. The transaction must use an authorized Electronic Notary Public, the prescribed identity checks, electronic signatures, and an accredited facility.

For a principal abroad, electronic notarization is allowed only in the limited circumstances stated in the rules, including physical presence within the premises of a Philippine embassy, consular office, or office of a Philippine honorary consul, with the required confirmation. Check the Supreme Court’s eNotary Services guidance and FAQs before relying on this option.

The pandemic-era remote procedure for paper documents was designed as an interim measure tied to community-quarantine conditions. An ordinary online meeting is not a substitute for either valid paper notarization or remote electronic notarization under the current system.

Affidavits executed outside the Philippines

A person abroad may usually consider either:

Executing the affidavit before a Philippine embassy or consulate that provides notarial services; or
Executing it before a competent local notary and obtaining an apostille from the foreign country’s competent authority when the Apostille Convention applies.

For a non-Apostille country, additional authentication or legalization may be necessary. Requirements vary by country, document, and intended use. Consult the relevant Philippine foreign-service post and the receiving office before execution.

A Philippine affidavit intended for use abroad may likewise need a DFA Apostille after meeting the documentary requirements applicable to notarized private documents. Current appointments, documentary requirements, processing periods, and fees are available from the DFA’s Authentication Division.

An apostille authenticates the origin of the public document or notarial certification; it does not certify that the affidavit’s factual statements are true or guarantee acceptance by the foreign recipient.

Special affidavits may follow different rules

Judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. It generally must follow a question-and-answer format, identify the lawyer who conducted or supervised the examination, contain the required sworn statements, and include counsel’s attestation.

Under the Judicial Affidavit Rule, parties generally file and serve judicial affidavits and exhibits no later than five days before the pretrial, preliminary conference, or scheduled hearing for motions and incidents. In covered criminal proceedings, an accused who elects to submit defense judicial affidavits generally has ten days from receipt of the prosecution’s affidavits.

Late submission is ordinarily treated as a waiver. A court may allow it only once under the rule’s conditions, including a valid reason, absence of undue prejudice, and payment of the court-imposed fine.

Complaint-affidavits and counter-affidavits

For preliminary investigation, affidavits must comply with Rule 112 of the Rules of Criminal Procedure. They are generally subscribed and sworn to before a prosecutor or government official authorized to administer oaths—or, in the official’s absence or unavailability, before a notary who must certify personal examination and satisfaction that the affiant voluntarily executed and understood the affidavit. Follow the prosecutor’s subpoena and stated filing period.

Agency and regulatory affidavits

Government agencies may impose their own forms, recency rules, attachments, filing channels, and deadlines. A generally valid notarization does not excuse noncompliance with those requirements.

Common mistakes to avoid

Signing before meeting the notary when a jurat is required.
Sending another person to “have it notarized.”
Using an expired, unreadable, or mismatched ID.
Leaving dates, names, amounts, annex references, or material paragraphs blank.
Using an acknowledgment when the document must be sworn.
Copying a generic online form that omits a required agency statement.
Stating assumptions, hearsay, or legal conclusions as personal knowledge.
Attaching altered, incomplete, or selectively cropped records.
Backdating the affidavit or the notarial certificate.
Adding pages or changing material language after notarization.
Assuming notarization automatically transfers property, creates authority, corrects a civil-registry entry, proves ownership, or wins a case.
Missing the receiving court’s or agency’s filing deadline while focusing only on notarization.
Paying a fixer who promises notarization without personal appearance.

When legal help is urgent

Consult a Philippine lawyer promptly when the affidavit:

Will be filed in a pending court, prosecution, administrative, immigration, tax, land, labor, or election matter.
Responds to a subpoena, demand letter, complaint, or deadline.
Concerns arrest, detention, threats, domestic violence, child safety, or immediate loss of property.
Admits possible criminal, civil, tax, employment, or regulatory liability.
Involves a deceased person’s estate, disputed ownership, inheritance, forgery, or unauthorized sale.
Will be used to withdraw a complaint, waive rights, acknowledge a debt, or settle a dispute.
Was allegedly signed without appearance, under pressure, or using a false notarial certificate.
Contains information you now believe is false or materially incomplete.

Do not “correct” a filed affidavit by destroying or silently replacing it. Ask the receiving authority or a lawyer whether a supplemental, amended, or retracted affidavit is procedurally proper.

Consequences of a false affidavit

Knowingly making a material false statement under oath can constitute perjury when the statutory elements are present. Depending on the conduct, falsification, use of falsified documents, obstruction, contempt, administrative liability, or civil liability may also arise.

Not every inaccurate statement automatically establishes a crime; materiality, knowledge, intent, authority to administer the oath, and the purpose for which the law required the affidavit can matter. However, signing an affidavit without reading it is dangerous and does not make false statements harmless. The current perjury provision is in Republic Act No. 11594.

Frequently asked questions

Can any lawyer notarize an affidavit?

No. The lawyer must hold a current notarial commission and act within its authorized jurisdiction. Admission to the Philippine Bar alone is insufficient.

Must every affidavit be notarized?

An affidavit, by definition, is made under oath or affirmation before a competent officer. Some particular proceedings authorize a prosecutor, court officer, consular officer, or government official to administer the oath, so a private notary may not always be necessary.

Can I use a photocopy of my ID?

Bring the original current ID. A copy may be retained for records, but relying only on a photocopy may prevent reliable identification.

Does an affidavit need witnesses?

An ordinary affidavit does not automatically require subscribing witnesses. A specific statute, form, transaction, disability procedure, or agency may require them. Credible identity witnesses serve a different purpose.

Can two people sign one joint affidavit?

Yes, when a joint affidavit is appropriate, but each affiant must satisfy the identification, appearance, signing, and oath requirements. Each is responsible for the statements sworn to.

Does a notarized affidavit expire?

There is no universal expiration period for all affidavits. The receiving office may require an affidavit executed within a specified period, and later events may make an older affidavit inaccurate or insufficient.

Can a notary correct the affidavit after signing?

Minor clerical issues should be corrected through a transparent procedure before completion of the notarial act. Material changes after notarization generally require proper re-execution and a new notarization. Never alter the jurat, seal, register details, or substantive text yourself.

Does notarization prove that the facts are true?

No. A valid jurat establishes that the identified affiant appeared, signed, and swore or affirmed to the document under the applicable procedure. The truth and evidentiary weight of the statements may still be challenged.
