Quick answer

A Philippine affidavit must be a written statement of facts made under oath or affirmation. For an ordinary paper affidavit, the affiant must personally appear before a duly commissioned notary public, prove identity, sign the complete document in the notary’s presence, and swear or affirm that its contents are true. The notary then completes the jurat, signs and seals it, and records the act in the notarial register.

Bring at least one current government-issued identification document bearing both your photograph and signature. A Community Tax Certificate, TIN, photocopy, or unsigned identification card alone may not satisfy the identification rule.

Quick answer

A Philippine affidavit must be a truthful written statement made under oath or affirmation. For an ordinary paper affidavit, the affiant must personally appear before a duly commissioned notary public, prove identity, sign the complete document in the notary’s presence, and take an oath or affirmation. The notary then completes the jurat, affixes the official signature and seal, and records the act in the notarial register.

Bring at least one current government-issued identification document bearing both your photograph and signature. A Community Tax Certificate or TIN alone is not sufficient proof of identity. Do not sign beforehand unless the notary specifically instructs you to do so under a valid electronic-notarization process.

Electronic notarization is also legally permitted for electronic documents, but only through a commissioned Electronic Notary Public and a Supreme Court-accredited Electronic Notarization Facility. An ordinary video call, emailed scan, or electronic signature by itself is not notarization.

What makes a document an affidavit?

An affidavit is more than a signed narrative. It ordinarily contains:

The affiant’s identity, address, and relevant personal or representative capacity;
Clear, numbered statements of fact;
A statement showing why the affidavit is being made;
The affiant’s signature; and
A proper jurat showing that the affiant personally appeared, was identified, signed, and swore or affirmed that the document was true.

The facts should come from the affiant’s personal knowledge or be clearly identified as based on authentic records. Do not present assumptions, rumors, or another person’s account as facts personally witnessed.

The notary administers the oath and certifies the appearance, identification, signing, and other required formalities. Notarization does not mean that the notary independently investigated every statement, guaranteed that the document is legally sufficient, or confirmed the truth of all its contents.

Is notarization always required?

An affidavit, by its nature, must be sworn or affirmed before a person legally authorized to administer an oath. That person is commonly a notary public, although certain judges, clerks of court, constitutional officers, government officials, and other officers may administer oaths within the authority granted by law. A receiving agency may require the oath to be administered by a particular officer.

Not every contract, authorization, declaration, or written statement must be notarized. Under Articles 1356 to 1358 of the Civil Code, contracts are generally binding in whatever form they are made when their essential requirements exist, unless the law requires a particular form for validity, enforceability, convenience, registration, or effect against third persons.

A public document is specifically required for several transactions listed in Article 1358, including acts affecting real rights over immovable property, certain hereditary rights, and particular powers of attorney. Other laws impose special formalities—for example, donations of immovable property and notarial wills. The exact document and transaction must therefore be checked; adding a notarial seal cannot cure missing consent, authority, witnesses, consideration, or another form required by law.

Requirements for a paper affidavit

Prepare a complete and accurate document

Before appearing before the notary:

Use the form required by the court, prosecutor, bank, school, employer, insurer, registry, or government agency, if one exists.
Confirm that names match the relevant IDs and supporting records. Explain genuine discrepancies instead of silently using different spellings.
State material dates, places, amounts, identifying numbers, and events accurately.
Identify attachments and mark them consistently with references in the affidavit.
Remove unfilled alternatives and complete all material blanks. Write “N/A” where appropriate.
Check every page, attachment, and amendment before signing.
Bring the number of originals and copies required by the receiving office and the notary.

There is no universal rule that every affidavit must contain the same personal details, witness count, attachments, or wording. The governing law and the receiving office’s instructions control.

Appear personally

For a traditional paper jurat, the affiant must personally appear before the notary. A relative, assistant, messenger, or attorney-in-fact cannot take the affiant’s oath or sign an affidavit as though the facts were personally sworn to by the absent affiant.

The jurat requires the affiant to sign in the notary’s presence and take an oath or affirmation concerning the document. The Supreme Court has repeatedly held that telephone confirmation, a later appearance, or an ordinary video call does not satisfy the personal-appearance requirement for paper notarization.

Present competent evidence of identity

Under the 2004 Rules on Notarial Practice, as amended, competent evidence of identity ordinarily means at least one current identification document issued by an official agency and bearing the individual’s photograph and signature. Examples recognized by the Rules include a passport, driver’s license, PRC ID, SSS card, GSIS e-card, and other qualifying government-issued identification.

Important points:

The ID must be current and must satisfy the photograph-and-signature requirement.
A Community Tax Certificate, TIN, or unsigned identification number alone is not competent evidence of identity.
A document that lacks a specimen signature may prompt the notary to request a supplementary qualifying ID.
Bring the original ID, not merely a photograph or photocopy, unless the applicable electronic-notarization procedure provides otherwise.

If the affiant has no qualifying ID, the Rules provide a credible-witness alternative:

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 qualifying documentary identification to the notary.

This is not a shortcut using any available friend. Arrange it with the notary beforehand because all legal conditions must be met.

Take the oath or affirmation and sign

The affiant must understand the document and voluntarily swear or affirm that its contents are true. For a paper affidavit, signing should occur in the notary’s presence.

A notary must refuse the act when there is reason to believe that:

The transaction is unlawful or immoral;
The signatory does not understand its consequences;
The signatory is acting under force, intimidation, or improper pressure;
The document or notarial certificate is blank or incomplete; or
The requested certificate would contain false information.

If the affiant cannot physically sign or make a mark, the Rules contain a narrow procedure allowing the notary to sign at the person’s direction in the presence of two disinterested and unaffected witnesses, with prescribed signatures and notation. Do not improvise this procedure; inform the notary in advance.

Check the completed jurat

Before leaving, examine the document. A proper jurat should reflect the actual date and place of notarization and contain the notary’s completed certificate, signature, seal, and notarial-register references. It should not contain blank dates, blank identification details, or missing document, page, book, and series information where required.

Keep at least one complete copy showing every attachment and the finished jurat.

Jurat versus acknowledgment

These acts serve different purposes and should not be interchanged.

Notarial act	What the signer does	Common use
Jurat	Personally appears, is identified, signs in the notary’s presence, and takes an oath or affirmation concerning the document	Affidavits, sworn statements, and documents whose contents must be verified under oath
Acknowledgment	Personally appears, is identified, and declares that the signature was voluntarily affixed and that the instrument is the signer’s free and voluntary act; a representative also declares authority to sign	Deeds, contracts, powers of attorney, and similar instruments

The Supreme Court’s definitions appear in the 2004 Notarial Rules and decisions such as Kiener v. Amores and Chua v. Gomos.

An affidavit ordinarily requires a jurat. Using a jurat on a deed that legally calls for an acknowledgment may deprive the deed of the evidentiary effect associated with a properly acknowledged public document.

Who may notarize—and who must decline?

Being a lawyer does not automatically authorize someone to notarize. The lawyer must hold a current notarial commission and act within its territorial and other limitations.

For traditional notarization, the act is ordinarily performed at the notary’s regular place of work or business within the territorial jurisdiction of the commissioning court. The Rules permit limited exceptional locations within that jurisdiction, including specified public venues, medical institutions where a party is confined, and places where a party is detained.

A notary is disqualified when the notary:

Is a party to the document or transaction;
Will receive a prohibited direct or indirect interest or benefit from it; or
Is the principal’s spouse, common-law partner, ancestor, descendant, or relative by consanguinity or affinity within the fourth civil degree.

Before relying on an unfamiliar notary, check the displayed commission details or verify the commission with the Office of the Clerk of Court of the Regional Trial Court that issued it.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, effective March 2025, supplement traditional notarization. They apply to electronic documents in PDF or PDF/A format and provide two modes:

In-Person Electronic Notarization: The principal and required witnesses physically appear before an Electronic Notary Public while using an accredited electronic facility.
Remote Electronic Notarization: The principal and required witnesses appear virtually through the videoconferencing and identity-verification functions of an accredited facility.

Electronic notarization requires both:

A separately commissioned Electronic Notary Public; and
A Supreme Court-accredited Electronic Notarization Facility.

A traditional notarial commission does not automatically authorize electronic notarization. Check the Supreme Court’s eNotary Services page and official directories before using a provider.

The electronic rules do not govern paper documents bearing handwritten signatures or marks, notarial wills, or depositions. The former 2020 interim rules allowing remote notarization of paper documents have been repealed. Consequently, sending a signed paper affidavit to a notary and appearing over an ordinary video call is not a valid substitute for current paper or electronic procedures.

For remote electronic notarization, the Electronic Notary Public must be physically located in the Philippines. The Rules generally contemplate participants located in the Philippines, with a limited procedure for a principal abroad who is within the premises of a Philippine embassy, consular office, or Philippine honorary consul and whose location is confirmed as required by the Rules.

Affidavits signed abroad

Before execution, ask the Philippine receiving office which form of authentication it will accept. Common routes include:

Signing before a Philippine embassy or consulate, subject to that post’s appointment, identification, copy, and fee requirements;
Signing before a foreign notary and obtaining an apostille from the competent authority of the country of origin if that country and the Philippines apply the Apostille Convention; or
Following the required authentication or legalization chain when the originating country is not covered by the Apostille Convention.

A foreign document cannot be apostilled by the Philippine DFA. Apostilles for foreign documents come from the competent authority of the country where the document originated. The DFA’s official Apostille FAQ and documentary-requirements page explain the distinction.

Consular requirements vary by post and document type. Do not assume that a locally notarized affidavit, an electronic signature, or a remote electronic notarization will satisfy a Philippine court, land registry, immigration authority, or other receiving office without confirmation.

Deadlines, validity, and fees

There is no single nationwide rule that every affidavit expires after a fixed number of days or months. Its usefulness may end because:

The receiving office requires a recently executed affidavit;
The facts have changed;
A statutory, court, prosecutorial, contractual, or administrative filing deadline has passed; or
The affidavit was prepared for a transaction that has already occurred or been cancelled.

The date in the jurat must be the actual date the oath and notarial act occurred. A notary should not backdate or postdate the certificate.

Notarial fees, separately agreed travel expenses in permitted cases, drafting charges, and electronic-facility costs are not necessarily the same. Ask for the amount before proceeding and distinguish the fee for the notarial act from any fee for legal drafting or advice. No additional fee may be imposed merely for the digitization and electronic transmittal required under the amended traditional notarial rules.

Evidence to preserve

Keep:

The complete notarized original or a clear copy of every page;
All attachments exactly as presented;
Copies or details of the identification used;
The notary’s name, office address, commission number, territorial jurisdiction, and commission expiry;
The document, page, book, and series numbers;
Receipts and appointment confirmations;
The receiving office’s form, checklist, email, or written instructions;
Drafts and records supporting each material statement; and
For electronic notarization, the finalized electronic file, verification data, transaction reference, and electronic notarial certificate.

For an affidavit of loss, preserve records showing ownership, identifying numbers, when and where the item was last held, when the loss was discovered, and any report or steps taken. For property, inheritance, corporate authority, or financial matters, preserve the underlying titles, resolutions, civil-registry records, contracts, and communications.

Common mistakes

Signing a paper affidavit before meeting the notary;
Allowing a messenger or relative to “process” notarization without the affiant;
Using only a Community Tax Certificate, TIN, photocopied ID, expired ID, or an ID without the required photograph and signature;
Leaving material spaces or attachments incomplete;
Swearing to information supplied by someone else as though personally witnessed;
Using an acknowledgment when a jurat is required, or vice versa;
Failing to disclose that the signer acts for a corporation, estate, minor, or another principal;
Altering the affidavit after notarization;
Accepting a seal without complete register details;
Using a notary outside the notary’s authorized territory;
Treating an ordinary video call or emailed scan as electronic notarization; and
Assuming notarization proves ownership, authority, consent, or legal validity.

What happens if notarization is defective?

Defective notarization commonly strips a document of the public character and evidentiary presumptions that a properly notarized document may receive. Its execution and authenticity may then have to be proved as a private document.

Defective or missing notarization does not automatically invalidate every underlying agreement. The result depends on whether the governing law makes the particular form essential. For example, the Supreme Court has held that irregular notarization does not necessarily invalidate an otherwise perfected sale, while a donation of immovable property is subject to stricter formal requirements. See B.E. San Diego, Inc. v. Court of Appeals and Palada v. Solidbank Corporation.

If the signature, appearance, authority, or register entry is disputed:

Preserve the questioned original and do not write on it.
Ask the relevant RTC Clerk of Court whether the notary held a valid commission and whether the notarial entry or filed duplicate exists.
Preserve proof of the purported signer’s location, travel, handwriting, identification, communications, and authority on the stated date.
Notify any institution that may act on the document if fraud or identity theft is reasonably suspected.
Obtain legal advice before signing a replacement affidavit, issuing accusations, or surrendering the original.

Knowingly making a materially false statement under oath can constitute perjury. Under Republic Act No. 11594, perjury under Article 183 of the Revised Penal Code is punishable by prision mayor in its minimum period, with additional consequences stated in the law. A public officer or employee who commits the offense is subject to the maximum period specified by the amendment.

When legal help is urgent

Seek prompt advice from a Philippine lawyer when:

A court, prosecutor, regulator, or government deadline is near;
The affidavit concerns land, inheritance, a mortgage, a donation, a waiver, a quitclaim, or a substantial financial obligation;
Someone is being pressured to sign or does not understand the document;
A signature, seal, identification, authority, or notarial entry may be forged;
A blank or incomplete document was signed;
A notarized special power of attorney is being used to sell, mortgage, withdraw, settle, or transfer valuable property;
The affiant is abroad and the receiving office has not confirmed the acceptable execution method;
The document involves a child, guardianship, travel consent, immigration, or civil-status records; or
A receiving office has rejected the affidavit and the filing period may expire before correction.

Frequently asked questions

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

For a traditional paper jurat, no. The affiant must sign in the notary’s presence and take the oath or affirmation. A properly conducted electronic jurat follows the separate electronic rules.

Is one valid ID enough?

One current official-agency ID bearing both photograph and signature can satisfy the basic rule. A notary may reasonably request another document if the first ID is damaged, inconsistent, difficult to verify, or lacks a required feature.

Is a barangay clearance or Community Tax Certificate enough?

A Community Tax Certificate alone is not competent evidence of identity. A qualifying barangay certification may fall within the examples in the Rules only if it meets the applicable current-identification requirements, including photograph and signature. Confirm acceptance with the notary beforehand.

Does the affidavit need witnesses?

Not every affidavit requires subscribing witnesses. Witnesses may be required by the governing law, prescribed form, receiving office, credible-witness identity procedure, or a special signing arrangement. Do not add or omit them based only on a generic template.

Can any lawyer notarize my affidavit?

No. The lawyer must have a valid notarial commission. Electronic notarization requires a separate electronic notarial commission.

Can an affidavit be notarized online?

Yes, if it is an electronic document processed by a commissioned Electronic Notary Public through a Supreme Court-accredited facility under the 2025 Rules. An ordinary Zoom call, scanned wet signature, or emailed seal is insufficient.

Does notarization prove that every statement is true?

No. The affiant remains responsible for the statements. Admissibility and evidentiary weight depend on the applicable law and procedure, and the affiant may still be required to testify or undergo cross-examination.

Does a notarized affidavit last forever?

There is no universal expiry period. The receiving office may require a recently executed affidavit, and an affidavit should be updated when material facts change.

Can I correct the document after notarization?

Do not alter a completed notarized affidavit. Material corrections ordinarily require a properly corrected document and a new oath and notarization. Ask the receiving office whether it also needs an explanatory or supplemental affidavit.
