Quick answer

An affidavit is a written statement of facts made under oath or affirmation. In the Philippines, it ordinarily becomes a proper affidavit only when the affiant personally appears before a commissioned notary public—or another officer specifically authorized to administer the oath—proves their identity, signs in the officer’s presence, and swears or affirms that the statements are true.

For traditional paper notarization, do not simply send a signed document or ask someone else to have it notarized. The affiant must personally appear. Bring the complete affidavit, supporting documents, and at least one current government-issued identification document bearing the affiant’s photograph and signature. A cedula or community tax certificate alone is not competent evidence of identity.

Electronic notarization is also permitted, but only through a Supreme Court-accredited electronic notarization facility and a commissioned Electronic Notary Public. An ordinary video call, emailed signature page, or online meeting with a conventional notary is not enough.

Notarization verifies the notarial act, identity, appearance, signature, oath, and voluntariness required by law. It does not prove that every statement in the affidavit is true, cure false information, establish ownership, or make an otherwise illegal transaction valid.

Does every affidavit need to be notarized?

A document that is genuinely intended to operate as an affidavit must be sworn or affirmed before a person authorized to administer oaths. This is normally shown by a jurat, commonly beginning with “Subscribed and sworn to before me.”

Not every written declaration needs to be an affidavit. Some statutes, court rules, government forms, or private institutions accept an unsworn declaration, certification, verification, or simple signed statement. Others expressly require a “notarized affidavit,” “sworn statement,” or affidavit in a prescribed form.

Always check the exact rule or checklist of the receiving court, agency, bank, school, employer, insurer, or other institution. A notarized document may still be rejected if it uses the wrong form, lacks required statements or attachments, or is submitted late.

Jurat and acknowledgment are different

Notarial act	Usually used for	What the signer must do
Jurat	Affidavits, sworn statements, verifications and similar documents	Personally appear, sign the document in the notary’s presence, and take an oath or affirmation that its contents are true
Acknowledgment	Deeds, contracts, powers of attorney and instruments executed as a free and voluntary act	Personally appear and declare that the signature was voluntarily affixed and that the document is the signer’s free act and deed; a signature may have been affixed earlier
Signature witnessing	Documents for which witnessing—not an oath—is the required act	Sign in the notary’s presence
Copy certification	Permitted copies of certain documents	Present the document and comply with the requirements for certification

An affidavit normally calls for a jurat, not merely an acknowledgment. The Supreme Court has emphasized that a jurat requires both signing in the notary’s presence and taking the oath or affirmation. An acknowledgment cannot be substituted merely because it is more convenient. See the 2004 Rules on Notarial Practice and the Supreme Court’s discussion in Dela Rama v. Papa.

What a usable affidavit should contain

There is no single universal affidavit format. The required contents depend on its purpose, but a careful affidavit usually contains:

The correct title or caption required by the receiving office;
The affiant’s complete name and relevant identifying or address information;
A statement that the affiant is competent to testify and is making the affidavit voluntarily;
Numbered, chronological statements of facts within the affiant’s personal knowledge;
Exact names, dates, places, amounts and document references where material;
The specific purpose for which the affidavit is executed;
Properly identified attachments or annexes, if required;
The affiant’s signature;
A complete jurat; and
The notary’s signature, seal, commission information and notarial register details.

Use the prescribed government or institutional form when one exists. Do not add legal conclusions, accusations, estimates, or hearsay merely to make the document sound stronger. If a fact came from another person or record, identify the source accurately instead of presenting it as personal knowledge.

If the affidavit will be filed in court, with a prosecutor, or in an administrative proceeding, special rules may govern its format, attachments, language, execution, filing method and deadline. A generic affidavit downloaded online may not satisfy those rules.

Identification requirements

Under the traditional rules, the notary may identify an affiant through either:

Personal knowledge of the affiant; or
Competent evidence of identity.

Competent evidence generally means at least one current identification document issued by an official agency that bears the individual’s photograph and signature. Examples in the Rules include a passport, driver’s license, PRC ID, SSS or GSIS card, and other qualifying government-issued identification.

The legal threshold is at least one compliant ID, but a notary or receiving institution may request additional identification when names, signatures, addresses or other details do not match.

A cedula alone is insufficient because it does not contain the photograph-and-signature safeguards required by the Rules. The Supreme Court has repeatedly applied this requirement, including in Edayan v. Larrazabal.

If the affiant lacks a qualifying ID, the Rules provide a limited credible-witness procedure:

One credible witness who is not involved in the document or transaction may identify the affiant if that witness is personally known to the notary and personally knows the affiant; or
Two credible witnesses, neither of whom is involved in the document or transaction, may identify the affiant if each personally knows the affiant and presents the required documentary identification.

This is not a shortcut allowing a relative, buyer, seller, beneficiary, co-affiant or other interested person to vouch for the signer.

Personal appearance is mandatory

For traditional paper notarization, the affiant must be physically present before the notary at the time of the notarial act. The notary must verify identity, witness the signing required for a jurat, administer the oath or affirmation, and determine that the act is voluntary.

The affiant must also sign or place the appropriate thumbmark or other mark in the notarial register. A secretary, liaison, relative, employer or document processor cannot appear in the affiant’s place.

Avoid any service that offers to notarize an affidavit:

Without seeing the affiant;
Through an ordinary video call outside the electronic-notarization system;
Using only a photocopy or emailed ID;
Through a pre-signed jurat;
With a backdated certificate; or
By having office staff affix a lawyer’s signature or seal.

The Supreme Court treats personal appearance as a fundamental safeguard against forgery, impersonation and coercion. A notary who ignores it may face revocation of the notarial commission and professional discipline.

Signing, blanks and corrections

Bring a complete document, but leave the affiant’s signature unsigned until the notary directs the signing if the affidavit requires a jurat.

A notary must not notarize a blank or incomplete instrument or attach a signature and seal to an incomplete notarial certificate. Before signing:

Fill in all material names, dates, addresses, amounts and descriptions;
Confirm that all referenced annexes are attached;
Remove unused blank spaces where additions could later be inserted;
Check that every page belongs to the same final document;
Correct errors before notarization; and
Make sure all signers are using the same final version.

Do not erase, replace pages or make material changes after notarization. If a material correction is needed, the safest course is usually to prepare and notarize a corrected affidavit or, where appropriate, a supplemental affidavit.

The notarial date must be the actual date of appearance and oath. It cannot lawfully be changed to an earlier date merely to meet a filing deadline.

Who may notarize an affidavit?

A Philippine lawyer is not automatically authorized to notarize. The lawyer must hold a valid notarial commission and act within the territorial jurisdiction of the commissioning court. Traditional commissions are generally valid for two years, unless earlier revoked or terminated.

Check the notarial certificate for the notary’s:

Name and signature;
Official seal;
Commission number and expiration;
Office address;
Roll of Attorneys number;
IBP and professional tax receipt details; and
Document, page, book and series numbers.

A notary should ordinarily act at the registered place of work or business, subject to the limited exceptions in the Rules. The Office of the Clerk of Court for the relevant Regional Trial Court may be asked to verify a notary’s commission or notarial entry when authenticity is in doubt.

A notary is disqualified when the notary is a party to the document, has a prohibited direct or indirect interest in it, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

Certain judges, clerks, prosecutors, consular officers and other public officials may administer oaths only when a law or rule gives them that authority and the act falls within their official functions. Do not assume that every government employee may notarize a private affidavit.

When a notary must refuse

A responsible notary should refuse or pause the notarization when:

The document or notarial certificate is blank or incomplete;
The affiant does not personally appear;
Identity cannot be established;
The affiant does not understand the document or cannot communicate adequately;
The affiant appears confused, incapacitated, coerced or unwilling;
The transaction appears unlawful or immoral;
The requested certificate contains false information;
The notary is disqualified because of relationship or interest; or
The requested act is outside the notary’s authority or territorial jurisdiction.

Refusal in these circumstances protects the affiant and everyone who may later rely on the document.

If a person cannot physically sign or make a mark, the Rules provide a special procedure allowing the notary to sign at that person’s express direction in the presence of two disinterested and unaffected witnesses, with specific wording and signatures. Inform the notary before the appointment so the proper procedure and witnesses can be arranged.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement rather than replace traditional notarization. Paper documents under the traditional system remain governed by the 2004 Rules, as amended.

Electronic notarization may be performed through:

In-Person Electronic Notarization, where the principal physically appears before the Electronic Notary Public; or
Remote Electronic Notarization, where the principal appears synchronously by videoconference through an accredited Electronic Notarization Facility.

The facility—not an ordinary messaging or videoconferencing application—must handle identity verification, authentication, location controls, document integrity and the electronic notarial record. For an electronic jurat, the affiant must apply the electronic signature through the facility in the Electronic Notary Public’s full view and take the oath.

Except for the limited overseas procedure, parties using remote electronic notarization must be located in the Philippines. An overseas principal may use Philippine electronic notarization only while physically within a Philippine embassy, consular office or honorary-consul office, with the location confirmed as required by the Rules.

Notarial wills, depositions and traditional paper documents remain subject to their separate governing rules. The Supreme Court’s eNotary Services FAQs provide current official guidance.

The 2004 Rules were also amended effective June 21, 2025 to require digital reporting and safeguards for traditional notarization. Notaries may not impose an additional charge for digitizing, transmitting, storing or processing documents under those requirements. See the 2025 amendments to the 2004 Rules.

Affidavits executed abroad

A person abroad generally has three possible routes, depending on the destination and receiving office:

Execute the affidavit before a Philippine embassy or consulate that provides notarial services;
Execute it before an authorized foreign notary and obtain an Apostille from the competent authority of the country of origin, if that country and the Philippines are parties to the Apostille Convention; or
Use the limited overseas electronic-notarization procedure while inside an eligible Philippine foreign-service post.

For a country outside the Apostille system, consular legalization or another authentication process may be required. Requirements, appointments, fees and processing times differ by country and consular post.

An Apostille authenticates the origin of the public document, including the capacity and signature or seal of the foreign official. It does not certify that the affidavit’s factual statements are true. Confirm the destination office’s requirements before paying for notarization, translation, Apostille or courier services. Consult the DFA’s Apostille FAQs and documentary requirements.

Practical step-by-step checklist

Identify the exact use. Obtain the current checklist, prescribed form and filing deadline from the receiving office.
Draft only supportable facts. Use personal knowledge, precise dates and neutral wording. Identify the basis of information derived from records.
Prepare annexes. Label attachments consistently and check that names and dates agree with the affidavit.
Confirm the required notarial act. An affidavit generally needs a jurat.
Contact the notary beforehand. Ask about accepted IDs, witnesses, copies, fees, accessibility needs and appointment rules.
Bring originals. Take the unsigned final affidavit, original qualifying ID, requested photocopies and original supporting records.
Appear and sign properly. Sign when instructed, take the oath or affirmation, and sign or mark the notarial register.
Inspect the completed document. Check the date, place, ID details, seal, commission information and Doc./Page/Book/Series entries.
Keep a complete copy. Preserve every page, annex and notarial certificate.
Submit through the authorized channel. Keep proof of filing, receipt, email acknowledgment, tracking record or electronic confirmation.

Evidence to preserve

Keep the following for as long as the underlying matter may be disputed:

The complete notarized original;
A clear scan of every page and annex;
The electronic copy transmitted by the notary, if applicable;
The receipt and fee information;
Appointment and correspondence records;
Copies or details of the identification presented;
Drafts showing how material corrections were made;
Source records supporting each important statement;
Proof of submission and the receiving office’s acknowledgment; and
For electronic notarization, the original electronic file, verification record, audit information and any permitted recording.

If the affidavit concerns loss, fraud, threats, an accident, employment, property or a disputed transaction, also preserve contemporaneous messages, photographs, CCTV requests, police or incident reports, medical records, payment records and witness contact details.

Common mistakes

Treating notarization as a rubber stamp;
Signing a jurat before meeting the notary;
Sending another person to “process” the notarization;
Using only a cedula for identification;
Leaving material blanks;
Copying a generic internet form that omits required agency language;
Mixing facts personally known by different affiants;
Attaching altered, incomplete or mislabeled records;
Assuming notarization proves ownership or the truth of every statement;
Backdating the affidavit to meet a deadline;
Making changes after the seal was affixed;
Assuming a notarized affidavit never expires; and
Confusing notarization with Apostille, consular legalization, filing or registration.

There is no universal expiration period for every affidavit and no single filing deadline for all affidavits. The receiving law, notice, transaction or institution controls. Some offices require a recently executed affidavit even if an older one remains formally notarized.

What defective notarization does—and does not do

A defect does not automatically produce the same result in every case. When personal appearance or another basic requirement is missing, the document may lose the evidentiary presumptions attached to proper notarization and may have to be proved as a private document. The Supreme Court has held that defective notarization does not necessarily void every underlying agreement, although a different result may follow when a statute makes a public instrument essential to validity, registration or a particular remedy. See Dela Rama v. Papa.

Even proper notarization ordinarily establishes due execution and authenticity—not the truth of every factual assertion in an affidavit. The Supreme Court clarified this distinction in Anido v. People.

Knowingly making a material false statement in a legally required affidavit may constitute perjury when all statutory elements are present. Republic Act No. 11594 increased the penalty for perjury and added a fine of up to ₱1,000,000, with additional consequences for a public officer or employee. See Republic Act No. 11594. Whether a particular error amounts to perjury depends on materiality, knowledge, intent, the purpose of the affidavit and the surrounding evidence; an honest mistake is not automatically perjury.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A court, prosecutor or agency deadline is approaching;
The affidavit is a complaint-affidavit, counter-affidavit, judicial affidavit or evidence in an active case;
It concerns real property, inheritance, corporate authority, a substantial debt, waiver, settlement or special power of attorney;
Someone is asking you to sign facts you do not personally know;
A signature, notarial seal, commission or register entry may be forged or fabricated;
A document appears to have been notarized without your appearance;
The supposed affiant was abroad, incapacitated or already deceased on the notarial date;
You are being pressured, threatened or prevented from reading the document;
The affidavit must be used abroad or was executed abroad; or
A receiving office has rejected the document and the filing period may expire.

Do not sign merely because someone says the document is “for formality only.” Ask for a complete copy and independent advice.

Frequently asked questions

Can I sign the affidavit at home and bring it to the notary?

Not for a traditional jurat. The affiant must sign in the notary’s presence and take the oath or affirmation. A prior signature may be acknowledged for documents requiring an acknowledgment, but that is a different notarial act.

How many valid IDs are required?

The Rules generally require at least one current official-agency ID bearing the affiant’s photograph and signature, unless the person is personally known to the notary or the credible-witness procedure is properly used. A notary or receiving institution may request more.

Is a barangay certification always enough?

No. It must satisfy the identification requirements applicable to the transaction and contain the necessary identifying safeguards. Confirm acceptance with the notary beforehand.

Can a relative have my affidavit notarized for me?

No. The affiant must personally appear. A representative cannot take the oath or confirm personal knowledge in the affiant’s place.

Can two affiants sign one affidavit?

Yes, if a joint affidavit is appropriate, but each affiant must personally appear, establish identity, sign, take the oath and make the required notarial-register entry. Each should personally know the facts attributed to them.

Can an affidavit be notarized online?

Yes, but only through a commissioned Electronic Notary Public using a Supreme Court-accredited facility and the procedures in the Rules on Electronic Notarization. A conventional notary cannot replace personal appearance with an informal video call.

Does notarization make the affidavit’s contents automatically true?

No. It establishes the notarial acts performed and supports authenticity and due execution. The statements may still be challenged and must be assessed with the other evidence.

Can a notary draft my affidavit?

A lawyer may provide legal drafting services and, if properly commissioned and not disqualified, may also notarize the document. Drafting, legal advice and notarization are distinct services. The affiant remains responsible for reviewing the document and swearing only to truthful facts.

How much does notarization cost?

There is no single flat private-notary price applicable to every affidavit. The fee may depend on the document and lawful office schedule. The notary must post a schedule of chargeable fees. Ask about the fee before proceeding and request a receipt. No additional fee may be charged for the digitization and transmission required by the 2025 amendments.

Does a notarized affidavit expire?

Not automatically. Its continuing usefulness depends on whether the facts remain current and whether the receiving office imposes a recency period or filing deadline. Obtain a new affidavit when material facts have changed or the governing checklist requires a recent document.

Where can a suspicious notarization be checked?

Contact the Office of the Clerk of Court for the Regional Trial Court that commissioned the notary. Provide the notary’s name, commission details, date, document title and Doc./Page/Book/Series numbers. Preserve the questioned original and obtain legal advice before surrendering it.
