Quick answer

An affidavit is a written statement of facts that the maker—called the affiant—swears or solemnly affirms to be true. In the Philippines, a properly notarized affidavit ordinarily requires the affiant to:

Complete the affidavit without material blanks.
Personally appear before a duly commissioned notary public.
Prove identity through personal knowledge or competent evidence of identity.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its contents are true.
Sign or place the required mark in the notarial register.

This procedure is called a jurat. Merely signing an affidavit at home and sending it to a notary is not enough. A secretary, messenger, relative, or representative cannot appear and swear in the affiant’s place.

Electronic notarization is legally available under Supreme Court rules, but it must be performed by an authorized electronic notary through a compliant system and procedure. An ordinary video call, scanned signature, or emailed notarial page does not by itself create a valid electronic notarization.

There is no universal rule that every affidavit must be notarized or that all affidavits expire after a fixed period. The law, court, agency, contract, or transaction requiring the affidavit determines whether notarization is necessary, what facts and attachments must be included, and whether the document must have been executed recently.

What makes a document an affidavit?

A document is not an affidavit merely because it is titled “Affidavit.” Its essential feature is that the person making the factual statements swears or affirms their truth before an officer authorized to administer an oath.

A typical affidavit contains:

The affiant’s full name, citizenship, age or confirmation of legal age, civil status when relevant, and address
A statement that the affiant is competent to testify about the matters stated
Clear, numbered factual paragraphs
Identification of relevant people, places, dates, amounts, and documents
References to attachments, properly marked if required
The affiant’s signature
A jurat completed, signed, and sealed by the notary

The facts should be based on the affiant’s personal knowledge unless the particular proceeding permits information from records or other sources. Legal conclusions, exaggeration, and second-hand accusations may weaken the document even if it is notarized.

Jurat versus acknowledgment

These notarial acts are not interchangeable.

Notarial act	What the signer declares	Usual use
Jurat	The signer appears, signs in the notary’s presence, and swears or affirms that the document’s contents are true	Affidavits, sworn statements, verifications
Acknowledgment	The signer appears and declares that the signature is voluntary and that the document is the signer’s free act and deed	Contracts, deeds, powers of attorney and similar instruments

An affidavit normally needs a jurat, commonly beginning with “Subscribed and sworn to before me.” An acknowledgment stating only that the document is the affiant’s free act may not satisfy a requirement for a sworn statement.

Under the 2004 Rules on Notarial Practice, a jurat requires the individual to appear before the notary, present the document, be properly identified, sign in the notary’s presence, and take an oath or affirmation.

Personal appearance is mandatory

For conventional paper notarization, the affiant must be physically present before the notary at the time of the notarial act. The notary must be able to verify:

The affiant’s identity
That the affiant understands the document
That the signature is genuine
That the affiant is acting voluntarily
That the affiant is swearing or affirming to the truth of the statement

The Supreme Court has repeatedly held that notarization without the signatory’s personal appearance violates the Notarial Rules. Personal appearance cannot be replaced by a phone call, a photocopy of an ID, a pre-signed document delivered by another person, or an assurance from the affiant’s lawyer or relative. See, for example, Sanchez v. Inton.

A legitimate notary may therefore ask the affiant to sign again in the notary’s presence, even if the document was signed beforehand.

Acceptable proof of identity

If the notary does not personally know the affiant, identity must be established through competent evidence of identity. The general rule is at least one current identification document issued by an official agency bearing the individual’s photograph and signature.

The identification should be original, current, legible, and consistent with the name used in the affidavit. Bring additional supporting records if the ID reflects a former name, abbreviated name, married name, or a material discrepancy in spelling.

A community tax certificate or cedula, standing alone, is not competent evidence of identity under the current rule because it ordinarily lacks the required photograph and signature. The Supreme Court specifically addressed this point in Almo v. People.

If the affiant has no qualifying identification, the rules permit identification through credible witnesses:

One credible witness who is not a party to or interested in the transaction, personally knows the affiant, and is personally known to the notary; or
Two credible witnesses who are not parties to or interested in the transaction, each personally knows the affiant, and presents qualifying documentary identification to the notary

A notary may reasonably request more than one ID or supporting civil-registry documents where the identity, name, capacity, or authority of the affiant is unclear. Receiving agencies may also impose their own documentary requirements.

What to bring to the notary

Unless the particular office requires something different, prepare:

The complete, unsigned affidavit, or a version ready to be signed again
The original current government-issued photo-and-signature ID
A photocopy of the ID if requested for the notary’s records
Original or reliable copies of attachments mentioned in the affidavit
Proof of authority if signing for a corporation, association, estate, or other juridical or represented party
Any prescribed form, case number, reference number, or agency instructions
The required witnesses, if the document or transaction calls for them

Bring all pages, including annexes. Do not ask the notary to notarize only a detached signature page.

What happens during conventional notarization?

The notary should ordinarily:

Examine the affidavit for completeness and identify the required notarial act.
Verify the affiant’s identity and capacity.
Confirm that the affiant understands the document and is acting voluntarily.
Witness the affiant’s signature.
Administer the oath or affirmation.
Complete the jurat, including the place and date of notarization.
Sign and affix the official notarial seal.
Record the act in the notarial register.
Require the affiant—and applicable credible or signature witnesses—to sign or place the appropriate mark in the register.
State the document, page, book, series, and other required notarial details.

The notary’s register must record information including the date and time, type of notarial act, document description, principal’s name and address, evidence of identity when required, fee charged, and relevant witnesses. The affiant should check that the jurat is complete and that the notary’s commission details have not expired.

When a notary must or may refuse

A notary should not proceed when, among other reasons:

The affiant is absent
Identity cannot be established
The document or notarial certificate is incomplete
The affiant appears not to understand the act
The affiant is being forced, threatened, or improperly influenced
The notary knows or has good reason to believe the transaction is unlawful or false
The notary has a disqualifying interest
The notary is not commissioned for the place where the act is performed
The notarial commission has expired
The requested act is outside the notary’s authority

A notary is disqualified when the notary is a party to the document, will receive a direct or indirect commission or benefit 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. The Supreme Court applied the family-relationship prohibition in Revilla Jr. v. Asuncion.

The notary’s office staff may prepare documents and perform clerical work, but they cannot administer the oath, sign for the notary, or complete the notarial act in the notary’s absence.

Place of notarization and the notary’s authority

A conventional notary may act only within the territorial jurisdiction of the court that issued the commission and while the commission remains valid. A commission from one city or province does not automatically authorize notarization elsewhere.

Notarial services are generally performed in the notary’s regular office or place of business. The rules recognize limited circumstances for notarization elsewhere, including certain public ceremonies, appropriate public signing venues, a party’s residence, a hospital, a place of legal confinement, or an emergency. The location must still fall within the notary’s territorial authority. The governing limitations appear in the Supreme Court’s Rules on Notarial Practice outside a notary’s regular place of work.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC recognize:

In-person electronic notarization, where the principal and electronic notary are physically together; and
Remote electronic notarization, where appearance is made through the authorized electronic process.

Electronic notarization is not the same as sending a scanned affidavit to an ordinary notary. It requires an electronic notary public authorized for the service, compliant identity verification and appearance procedures, electronic signatures and seals, recording and retention safeguards, and use of the prescribed platform or system. The Supreme Court’s official eNotarization FAQs explain the permitted modes.

Before relying on remote notarization, confirm that:

The notary is currently authorized as an electronic notary public
The particular affidavit is eligible for electronic notarization
The receiving court, agency, bank, school, employer, foreign authority, or other recipient accepts the electronic document and its format
All identity, signing, recording, and platform requirements will be followed

A casual Zoom, Messenger, Viber, or other video call with an ordinary notary does not substitute for compliance with the electronic-notarization rules.

Does notarization prove that every statement is true?

No. Notarization establishes the formal notarial act and gives the document the status and evidentiary treatment associated with a notarized public document. It does not independently investigate or guarantee the truth of every factual claim.

The Supreme Court explains that proper notarization converts a private document into a public document and allows reliance on its apparent authenticity without the usual preliminary proof of due execution. But this presumption may be challenged with competent evidence, particularly where there was forgery, lack of appearance, an unauthorized notary, coercion, fraud, or another serious irregularity. See Dela Cruz v. Dimaano.

A defective notarization does not always erase the underlying document or transaction. Depending on the applicable law and facts, the instrument may be treated as a private document whose authenticity and due execution must be proved. Some transactions, however, have separate statutory form, registration, or public-instrument requirements, so the consequences of defective notarization can be more serious.

No universal validity period or filing deadline

An affidavit does not automatically expire after three months, six months, or one year merely because it was notarized. Its continuing usefulness depends on:

Whether the stated facts remain true
The purpose for which it was executed
A deadline fixed by law, court rule, agency instruction, contract, or requesting institution
Whether the recipient requires a recently executed affidavit
Whether later events have made the statement incomplete or misleading

Do not backdate an affidavit. If important facts have changed, execute a new or supplemental affidavit instead of reusing an inaccurate one.

Court and agency deadlines vary sharply. For example, judicial affidavits are governed by the separate Judicial Affidavit Rule, which prescribes their contents, lawyer’s attestation, submission deadlines, and consequences of late filing. A standard notarized affidavit should not be assumed to satisfy those specialized requirements.

Affidavits for court, prosecutors, and government agencies

Always use the form and instructions issued for the particular proceeding. Requirements may differ for:

Complaint-affidavits and counter-affidavits in criminal investigations
Judicial affidavits used as direct testimony
Affidavits of loss
Affidavits of support or consent
Affidavits of discrepancy, change, or correction
Affidavits connected with land, estates, taxes, immigration, employment, or benefits
Verifications and certifications against forum shopping
Corporate secretary’s or authorized representative’s affidavits

A receiving office may require original signatures, specified annexes, multiple copies, witnesses, proof of relationship, documentary stamps, or a prescribed filing channel. Notarization does not cure failure to follow those requirements.

For litigation or an investigation, do not revise a prescribed form casually. A missing certification, improper signatory, defective verification, or omitted annex may have consequences beyond ordinary notarization.

If the affidavit will be used abroad

Ask the foreign recipient exactly what it requires before signing. Depending on the destination and document, the process may involve:

Notarization in the Philippines followed by DFA Apostille or authentication
Execution before a Philippine embassy or consulate
Local notarization abroad followed by an apostille or other authentication accepted in the Philippines
Certified translation
Additional certification by the issuing or supervising office

An apostille authenticates the origin of the public document or official signature; it does not certify that the affidavit’s factual statements are true. Requirements differ by document and destination. Check the Department of Foreign Affairs’ official Apostille documentary requirements and Apostille FAQs before proceeding.

Evidence to preserve

Keep:

A clear copy or scan of the complete notarized affidavit
Every page and annex in the form submitted
Proof of filing, delivery, or receipt
The name, office address, commission details, and contact information of the notary
The document, page, book, and series numbers
Copies of the identification presented
Drafts and source records supporting each factual statement
Relevant messages, photographs, receipts, contracts, medical records, and official documents
For electronic notarization, the original electronic file, validation data, transaction record, and any issued verification link or certificate

Do not alter the affidavit after notarization. Handwritten additions, replaced pages, or changed annexes may invalidate or seriously undermine the document. Material corrections should ordinarily be incorporated into a clean document that is signed and notarized again.

Common mistakes to avoid

Signing outside the notary’s presence for a jurat
Asking another person to bring in a pre-signed affidavit
Using only a cedula as identification
Leaving dates, names, amounts, annex references, or other material spaces blank
Using an acknowledgment when a jurat is required
Allowing office staff to perform the notarial act
Using a notary whose commission has expired or does not cover the location
Not checking that the jurat, seal, and commission information are complete
Describing assumptions or rumors as personal knowledge
Omitting facts that make a statement misleading
Attaching documents different from those reviewed and sworn to
Editing the affidavit after notarization
Assuming notarization alone satisfies a court or agency’s special form and filing rules
Treating a video call or emailed scan as valid remote notarization without the authorized electronic process

Practical checklist

Before the appointment:

Confirm the recipient’s current form, attachments, copy, and recency requirements.
Check every statement against reliable records.
Resolve name and date discrepancies.
Arrange qualified witnesses if needed.
Confirm the notary’s office, territorial authority, commission, fee, and accepted IDs.

During notarization:

Appear personally through the legally proper mode.
Present original identification.
Read the final affidavit and annexes.
Correct errors before signing.
Sign only when directed.
Take the oath or affirmation.
Sign or mark the notarial register.
Check the completed jurat and notarial details.

After notarization:

Make a complete copy before filing.
Do not replace or alter any page.
File through the required channel before the applicable deadline.
Preserve proof of submission and the supporting evidence.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The affidavit may expose you or someone else to criminal, civil, tax, immigration, employment, or administrative liability
Police, prosecutors, regulators, or a court have required a complaint-affidavit, counter-affidavit, or sworn explanation
A filing deadline is approaching
You are being asked to admit wrongdoing, waive rights, transfer property, or assume another person’s debt
The document concerns land, inheritance, corporate authority, custody, domestic violence, trafficking, immigration, or a substantial amount of money
Someone is pressuring you to sign, omit facts, backdate the document, or use false attachments
Your signature appears on an affidavit you did not execute
The affiant is seriously ill, detained, unable to sign, outside the Philippines, or unable to understand the document without assistance
A court or agency has rejected the affidavit
You suspect that the notary was unauthorized or that the notarial record is false

If a deadline is imminent, contact counsel or the receiving office immediately rather than assuming that ordinary notarization will preserve your rights.

Frequently asked questions

Can I sign the affidavit before going to the notary?

For a jurat, the rules require signing in the notary’s presence. If you signed beforehand, the notary may require a fresh signature or a newly printed copy.

Can someone else have my affidavit notarized for me?

No. The person who is swearing or affirming to the affidavit must personally appear through the legally authorized mode.

Is one government ID enough?

One current official ID bearing your photograph and signature meets the general documentary definition, but the notary or receiving institution may reasonably require additional proof where identity, name, authority, or capacity is uncertain.

Is a barangay ID acceptable?

It may qualify if it is current, issued by an official government agency, and bears both the holder’s photograph and signature. Acceptance remains subject to verification by the notary and any stricter requirement of the recipient.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity under the current Notarial Rules.

Must every affidavit have witnesses?

Not automatically. The affiant’s oath and proper jurat are the central requirements. Witnesses may be required by a specific law, form, transaction, or identity-verification method.

Can a minor execute an affidavit?

Capacity and the proper signatory depend on the affidavit’s purpose, the minor’s understanding, and the governing law or agency rule. A parent, guardian, or legal representative may be required, but cannot simply swear to facts known only to the child. Obtain specific advice for court, travel, custody, abuse, inheritance, or property matters.

Can a person who cannot sign use a thumbmark?

The Notarial Rules recognize a thumb or other mark and signing by the notary on behalf of a person physically unable to sign, subject to prescribed safeguards and witnesses. Arrange this with the notary in advance; do not add a thumbmark without the required procedure.

Can I notarize a scanned or electronically signed affidavit?

Only through a valid electronic-notarization process conducted by an authorized electronic notary. Printing a scanned signature and attaching an ordinary seal is not an adequate substitute.

Does notarization make a false affidavit legal?

No. Knowingly making a materially false statement under oath may constitute perjury when the statutory elements are present. Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, provides serious criminal penalties. Correct an honest mistake promptly and obtain legal advice before submitting a replacement or explanation.

Can I use the same affidavit for several agencies?

Possibly, but only if its contents, form, attachments, date, and notarial act satisfy each recipient’s requirements. A recipient may insist on its own form or a newly executed original.

How can I check a suspicious notarization?

Examine the notary’s commission details and the document, page, book, and series numbers. For a dispute, forgery allegation, or court filing, seek legal assistance and ask about verification through the Office of the Clerk of Court that commissioned the notary. Do not confront or accuse anyone solely on the basis of an incomplete copy.
