Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. For an ordinary paper affidavit in the Philippines, the affiant must personally appear before a commissioned notary public or another officer legally authorized to administer the oath, prove identity, sign the complete document in that officer’s presence, and take the oath or affirmation. The officer then completes and signs the jurat.

A signature, stamp, or seal obtained without the affiant’s personal appearance is not proper traditional notarization. Sending a signed paper or scanned signature to a notary is not enough. Remote electronic notarization is lawful only through the regulated process under the Supreme Court’s 2025 Rules on Electronic Notarization—not through an informal video call or email exchange.

The exact affidavit form, attachments, filing method, and deadline depend on its purpose. Always follow the current instructions of the court, prosecutor, government agency, embassy, employer, bank, school, or other receiving institution.

What makes a document an affidavit?

An affidavit generally has three essential features:

A written statement of facts attributable to the affiant;
The affiant’s signature; and
A valid oath or solemn affirmation administered by an authorized officer, evidenced by a jurat.

The jurat is the portion—usually beginning with “Subscribed and sworn to before me”—in which the officer certifies that the affiant appeared, was properly identified, signed in the officer’s presence, and took an oath or affirmation. The Supreme Court has repeatedly treated the jurat as essential to an affidavit because it proves that the statement was actually made under oath. See the 2004 Rules on Notarial Practice and the Court’s discussion in Bides v. Salazar.

An unsigned draft, a signed but unsworn statement, or a document bearing only an acknowledgment may not satisfy a requirement for an “affidavit.”

Jurat versus acknowledgment

Using the wrong notarial certificate can cause rejection or an evidentiary problem.

Point	Jurat	Acknowledgment
Common use	Affidavits, verifications, sworn statements	Deeds, contracts, powers of attorney and similar instruments
Must the signer appear?	Yes	Yes
Must identity be established?	Yes	Yes
Must signing occur before the notary?	Yes	Not necessarily; the signer may acknowledge a previously affixed signature
Is an oath or affirmation administered?	Yes	No oath is inherent in an acknowledgment
What is certified?	The affiant signed and swore or affirmed to the document	The signer declared that the signature and instrument are the signer’s free and voluntary act

An affidavit normally needs a jurat, not merely an acknowledgment. Conversely, a deed ordinarily calls for an acknowledgment rather than a jurat. The Supreme Court explains the distinction in Ladrera v. Osorio.

What to include in an affidavit

Unless the receiving institution supplies a mandatory form, a practical affidavit usually contains:

The correct title or caption;
The venue, identifying the place where the oath will be administered;
The affiant’s complete name and relevant personal circumstances;
Clear, consecutively numbered statements of fact;
An explanation of how the affiant personally knows those facts;
Dates, places, persons, amounts, document numbers, and other material details, when known;
The specific purpose for which the affidavit is executed;
A list or identification of supporting documents attached as annexes;
The affiant’s signature over the printed name; and
A proper jurat completed by the authorized officer.

Use only facts that the affiant can truthfully affirm. Distinguish personal knowledge from information learned from another person. If an exact date or amount is genuinely unknown, say so accurately instead of guessing.

Do not leave material blanks. Write “not applicable” where appropriate, or revise the document before it is notarized. A notary must not notarize a blank or incomplete document or attach a signature and seal to an incomplete notarial certificate.

What to bring for traditional paper notarization

Bring:

The complete, final affidavit, including all referenced annexes;
The original of at least one current identification document issued by an official agency;
Any additional identification or supporting document requested for the particular transaction;
The required number of copies; and
Payment for the disclosed notarial or drafting fee.

Under the 2008 amendment to the Notarial Rules, competent evidence of identity generally includes at least one current official identification document bearing the person’s photograph and signature. Examples in the rule include a passport, driver’s licence, PRC ID, NBI or police clearance, government-office ID, SSS or GSIS card, senior-citizen card, and other qualifying official identification. The full rule is in the Supreme Court’s 2008 amendment on competent evidence of identity.

The PhilID is, by statute, official and sufficient proof of identity, subject to authentication. If using a physical, digital, or printed National ID that does not display a handwritten signature, confirm beforehand how the notary will authenticate it. See the Philippine Identification System Act.

A cedula or community tax certificate, standing alone, ordinarily does not satisfy the Notarial Rules’ photo-and-signature standard.

If the affiant has no qualifying ID

Identity may instead be established through:

One credible witness who is not privy to the document or transaction, personally knows the affiant, and is personally known to the notary; or
Two credible witnesses, neither of whom is privy to the document or transaction, who each personally know the affiant and present their own documentary identification.

Arrange this with the notary in advance. Bringing a friend who has just met the affiant, or a person who stands to benefit from the affidavit, does not satisfy the rule.

What should happen at the notary’s office?

For a paper affidavit with a jurat, the proper sequence is:

The notary examines the complete affidavit and supporting documents.
The affiant personally appears and presents competent evidence of identity.
The notary assesses whether the affiant understands the document and is acting voluntarily.
The affiant signs the affidavit in the notary’s presence.
The notary administers an oath or solemn affirmation.
The affiant signs or places the required mark in the notarial register.
The notary completes the jurat, signs it by hand, affixes the official seal, and records the act.

A notary must refuse if the document is blank or incomplete, the transaction appears unlawful or immoral, the affiant may not understand its consequences, or the affiant appears to be acting under coercion.

The notarial certificate should identify the notary, commission serial number, commissioning city or province, commission expiry date, office address, Roll of Attorneys number, professional-tax-receipt details, and IBP membership number. The document should also be traceable through its notarial-register details.

Where may traditional notarization take place?

A traditional notary’s authority is limited to the territorial jurisdiction of the commissioning court. As a rule, the notarial act must occur at the notary’s regular place of work or business.

The Notarial Rules allow limited exceptions within that territorial jurisdiction, including specified public offices or public places, hotels or similar venues for public functions, hospitals or medical institutions where a party is confined, and places where a party is detained. A house call or roadside notarization is not automatically valid merely because the notary agreed to travel.

A notary is also disqualified when the notary:

Is a party to the document or transaction;
Will receive a direct or indirect commission, fee, advantage, right, title, interest, cash, property, or other consideration beyond the proper notarial fee; or
Is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

Signing by thumbmark or for a person physically unable to sign

The Notarial Rules provide accommodations, but the formal safeguards must be followed.

A thumbmark or other mark may be used if it is affixed in the presence of the notary and two disinterested and unaffected witnesses. Both witnesses must sign, and the notary must include the prescribed notation identifying the person and witnesses.

If a person is physically unable to sign or make a mark, the notary may sign on that person’s behalf only when directed by the person and in the presence of two disinterested and unaffected witnesses. The witnesses must sign, and the prescribed notation and notarial act must be completed.

Do not improvise these arrangements. Inform the notary beforehand about any disability, literacy issue, language barrier, or need for an interpreter.

Electronic and remote notarization

The 2025 Rules on Electronic Notarization, A.M. No. 24-10-14-SC supplement traditional notarization. They cover electronic documents through:

In-Person Electronic Notarization: The electronic document is processed through an accredited facility while the principal physically appears before an Electronic Notary Public.
Remote Electronic Notarization: The principal appears virtually through live, synchronous videoconferencing within an accredited Electronic Notarization Facility.

For an electronic jurat, the principal must affix the electronic signature through the facility in full view of the Electronic Notary Public and take the oath or affirmation. Identity verification, authentication, geolocation, electronic records, the electronic notarial seal, and the notarial book are handled through the regulated facility.

Important limits include:

The notary must hold a separate electronic notarial commission; an ordinary notarial commission alone is insufficient.
The facility must be accredited by the Supreme Court.
Electronic documents must be in PDF or PDF/A format.
A prerecorded signing is prohibited.
An ordinary Zoom, Messenger, FaceTime, or email exchange is not a substitute for the accredited process.
Paper documents with handwritten signatures remain governed by the traditional rules.
Notarial wills and depositions remain outside the electronic-notarization framework.
The 2020 interim rules for remote notarization of paper documents have been repealed.

Use the Supreme Court’s eNotary Services page and official eNotary FAQs to verify currently available facilities and commissioned Electronic Notaries Public.

If the affiant is outside the Philippines

Remote electronic notarization has a limited overseas exception. The principal abroad must be within the premises of a Philippine embassy, consular office, or office of a Philippine Honorary Consul, and the rule’s location-confirmation requirements must be followed. The Electronic Notary Public must be in the Philippines.

Other common options are:

Personal execution before a Philippine embassy or consulate; or
Execution before a local foreign notary, followed by an Apostille where the country is a party to the Apostille Convention, or the applicable authentication process for a non-party country.

Requirements and appointment systems differ by country and by document. Confirm them with the relevant Philippine foreign service post and the receiving office. The DFA explains the general Apostille system in its official Apostille FAQs.

Fees and copies

There is no single nationwide flat peso price for every affidavit. The amount may depend on the authorized notarial fee, the document, local schedules, travel, and whether the lawyer separately drafted or reviewed it. Ask for a breakdown and an official BIR-registered receipt.

Under the 2025 amendments to the 2004 Notarial Rules:

A notary may not impose an additional charge for digitization, electronic transmission, storage, disposal, or related processing of the digitized notarial record.
A signatory may receive an electronic copy through email or another mutually agreed file-sharing method, generally within five days, at no additional cost.
A signatory may waive electronic transmittal, but the waiver affects the ability to object later to the completeness of the reproduction.
Material discrepancies between the paper document and transmitted electronic copy should be reported promptly to the notary in writing.

Check the electronic copy immediately against every page of the paper version.

Notarization does—and does not—prove

Proper notarization generally converts a private document into a public document, giving it a presumption of regularity and allowing its authenticity and due execution to be recognized without the same preliminary proof required for an ordinary private document.

That presumption is disputable. Notarization does not:

Guarantee that every factual statement is true;
Prove that attachments are authentic;
Cure fraud, forgery, coercion, lack of authority, or incapacity;
Make an unlawful transaction lawful;
Confirm that the affidavit satisfies a particular agency’s substantive requirements; or
Prevent the document from being challenged with sufficient evidence.

Defective notarization generally strips a document of its public character and reduces it to a private document. For an affidavit specifically required to be sworn, absence of a valid oath or jurat may mean the requirement was not met. For an underlying contract, the effect may differ: defective notarization does not invariably invalidate the agreement, unless the applicable law requires a public instrument or particular form for validity. The Supreme Court discusses these distinctions in Patenia-Kinatac-an v. Commission on Audit and Spouses Orbeta v. Spouses Sendiong.

Special requirements for judicial affidavits

A judicial affidavit is not simply an ordinary narrative affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it must generally:

Be in a language known to the witness, with an English or Filipino translation when necessary;
Identify the witness and the examining or supervising lawyer;
Present consecutively numbered questions and answers;
Establish how the witness learned the facts;
Identify and authenticate attached evidence;
Contain the witness’s signature and a jurat; and
Include the lawyer’s sworn attestation.

In covered proceedings, judicial affidavits and exhibits generally must be filed and served no later than five days before pre-trial, preliminary conference, or the scheduled hearing on a motion or incident. Late submission may be allowed only once upon the specified conditions, including a valid reason, absence of undue prejudice, and payment of a court-imposed fine of ₱1,000 to ₱5,000.

For criminal cases, the Rule applies when the maximum imposable penalty does not exceed six years, when the accused agrees regardless of the penalty, and to the civil aspect regardless of the penalty. Separate prosecution and defence deadlines apply. Follow the court’s current order rather than assuming that the ordinary five-day rule resolves every situation.

Complaint-affidavits and agency forms

A complaint-affidavit filed with a prosecutor, police unit, regulator, or other agency may have additional requirements concerning:

Who must administer the oath;
Number of copies;
Supporting affidavits and documents;
Certification that the affiant was personally examined and understood the affidavit;
Electronic or physical filing;
Venue and territorial jurisdiction; and
Limitation, prescription, appeal, or response periods.

Some procedures prefer or require subscription before the assigned prosecutor or another authorized government officer, with notarization allowed only when the designated officer is unavailable. Obtain the receiving office’s current checklist before execution.

There is no universal filing deadline for all affidavits. The governing deadline comes from the particular law, rule, order, notice, or transaction.

Evidence to preserve

Keep:

The complete notarized original;
A clear copy of every page and annex;
The electronic copy transmitted by the notary;
The official receipt;
The notary’s name, office, commission number, jurisdiction, and expiration date;
The document, page, book, and series details;
Proof of submission and receipt by the receiving institution;
Source records supporting the statements in the affidavit;
Relevant emails, messages, photographs, reports, and contemporaneous notes; and
For electronic notarization, the final PDF/PDF-A, verification information, QR code or other security feature, and any recording lawfully made available through the facility.

Preserve original electronic files and metadata. Do not overwrite, annotate, crop, or “correct” a disputed document.

Common mistakes to avoid

Signing a paper affidavit before meeting the notary;
Allowing another person to appear for the affiant;
Paying for a stamp while the notary is absent;
Using an acknowledgment when a jurat is required;
Leaving blanks to be completed later;
Attaching annexes after notarization;
Using an expired or unsuitable ID without arranging credible witnesses;
Giving dates, amounts, or names from memory without checking records;
Treating hearsay as personal knowledge;
Assuming notarization makes an affidavit legally sufficient for every purpose;
Using informal “online notarization” outside an accredited facility;
Ignoring the recipient’s prescribed form or filing deadline; and
Failing to compare the final notarized document with the copy submitted or electronically transmitted.

When legal help is urgent

Seek prompt advice from a Philippine lawyer if:

An affidavit has already been filed and contains a material error;
Someone asks you to sign a false, backdated, incomplete, or misleading affidavit;
You are being pressured, threatened, or instructed to conceal facts;
A document appears to have been notarized without your appearance;
Your signature, identity, land, inheritance, corporate authority, or property rights may have been forged or misused;
A court, prosecutor, regulator, or disciplinary deadline is approaching;
The affidavit may expose you to criminal, civil, tax, immigration, employment, or administrative liability; or
A foreign authority has rejected the document for lack of Apostille, authentication, translation, or proper execution.

For suspected irregular notarization, preserve the document and ask the Office of the Clerk of Court or Executive Judge of the commissioning Regional Trial Court to verify the notary’s commission and relevant records. If the document is already being used in a case or property transaction, notify counsel and the responsible court, prosecutor, agency, bank, or Registry of Deeds immediately.

Consequences of a false affidavit

Knowingly making an untruthful statement under oath on a material matter in an affidavit required by law or made for a legal purpose may constitute perjury if all statutory elements are proven. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, the prescribed penalty is prision mayor in its minimum period. The law provides heightened consequences where the offender is a public officer or employee, including the stated fine of up to ₱1,000,000 and perpetual absolute disqualification.

An honest mistake is not automatically perjury; the prosecution must prove the required knowing and willful falsehood concerning a material matter. Nevertheless, never sign an affidavit merely because someone says it is “only a formality.”

Frequently asked questions

Can I have an affidavit notarized without appearing personally?

Not under traditional paper notarization. The affiant must personally appear. Remote appearance is permitted only through the separate, regulated electronic-notarization process.

Can I sign the affidavit at home?

For a paper affidavit requiring a jurat, sign in the notary’s presence. If it has already been signed, the notary may require a fresh signature or properly re-executed document.

Is one ID enough?

Generally, one current official ID bearing the required photograph and signature is sufficient under the traditional rule. The notary may request more information when reasonably necessary, while the PhilID is subject to its own statutory authentication rules.

Can a non-lawyer notarize?

An ordinary Philippine notary public must be a lawyer in good standing with a valid notarial commission. Other public officers may administer oaths only within authority granted by law and, in many instances, only for matters connected with their official functions.

Does an affidavit expire?

There is no general expiration period for every affidavit. The receiving institution may require one executed within a specified period, and changed circumstances may make an older affidavit inaccurate or unacceptable.

Can I correct an affidavit after notarization?

Do not alter the notarized document. For a material correction, prepare and properly execute a corrected, supplemental, or new affidavit, then comply with any duty to notify the receiving institution.

Is a photocopy of a notarized affidavit valid?

A receiving office may accept a copy, certified copy, scanned copy, or only the original depending on its rules. Confirm before filing. A photocopy does not automatically have the same evidentiary treatment as the original.

Does every page need the affiant’s signature?

There is no single universal rule requiring the affiant’s full signature on every page of every affidavit, but receiving institutions often require initials or signatures on each page and annex. Follow the prescribed form and the notary’s compliant procedure.

Does notarization mean the notary agrees with the affidavit?

No. The notary certifies the notarial act—identity, appearance, signature, oath, and related formalities—not the ultimate truth or legal merit of every assertion.

Can a joint affidavit be notarized if only one affiant appears?

No. Each affiant whose sworn statement and signature are being notarized must appear, be identified, sign as required, and take the oath or affirmation.
