Quick answer

An affidavit is a written statement that the person making it—the affiant—swears or affirms is true before a notary public or another officer legally authorized to administer oaths. For an ordinary paper affidavit in the Philippines, the affiant generally must:

Use the form required by the court, agency, bank, school, employer, or transaction, if one is prescribed.
State truthful, relevant facts, preferably based on personal knowledge.
Bring the complete, unsigned affidavit and supporting documents to a duly commissioned notary public.
Personally appear before the notary.
Present acceptable proof of identity unless personally known to the notary.
Take an oath or affirmation and sign in the notary’s presence.
Sign or mark the notarial register as required.
Check that the jurat is complete, signed, sealed, dated, and supported by the notary’s commission details.

A notary should not notarize an affidavit through an ordinary video call, through a messenger, or merely because someone else presents a pre-signed document. Electronic notarization is possible only through the Supreme Court’s authorized system, using an accredited Electronic Notarial Facility and a properly authorized electronic notary.

Notarization does not prove that every statement in an affidavit is true. It establishes that the identified affiant personally appeared through the legally permitted procedure, took the oath or affirmation, and signed or confirmed the document as required.

What makes a document an affidavit?

A document labeled “Affidavit” is not necessarily a valid sworn affidavit. Its essential feature is the oath or affirmation administered by an authorized officer.

A properly prepared affidavit ordinarily contains:

The affiant’s complete name and relevant personal details
A clear statement of the affiant’s capacity or connection to the matter
Numbered statements of material facts
An explanation of which facts are personally known and, where appropriate, the basis of that knowledge
A statement of the purpose for which the affidavit is executed
References to clearly labeled attachments or exhibits
The affiant’s signature over the printed name
A jurat completed by the notary or other authorized officer

Court rules, statutes, and government agencies may prescribe additional wording, attachments, witnesses, translations, or filing requirements. Always use the receiving office’s current form or checklist when one exists.

Jurat versus acknowledgment

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

In a jurat, the affiant personally appears before the notary, signs in the notary’s presence, and takes an oath or affirmation that the document’s contents are true. The notary certifies that the document was subscribed and sworn to before them.

An acknowledgment serves a different purpose. The person acknowledges before the notary that they signed an instrument voluntarily for its stated purpose. Acknowledgments are commonly used for deeds, contracts, and powers of attorney.

Using an acknowledgment on a document that must be sworn may fail to satisfy the receiving court or agency. Conversely, using a jurat does not automatically meet a legal requirement for acknowledgment. The required notarial act depends on the document and governing rule.

Personal appearance is the general rule

For traditional notarization of a paper document with a wet signature, the affiant must be personally present before the notary at the time of notarization. A notary must not notarize merely because:

The signature appears genuine
The notary has seen the affiant before
A relative, employee, liaison, or messenger delivers the document
The affiant spoke to the notary by telephone
The affiant appears through an ordinary video-conferencing application
Another person promises that the affiant signed voluntarily
The document was signed before arriving at the notary’s office

Personal appearance allows the notary to identify the affiant, administer the oath, assess voluntariness, and verify the signature. The Supreme Court has repeatedly treated notarization without the signer’s presence as a serious violation of the notarial rules.

A person who cannot travel should discuss the situation directly with a commissioned notary. The rules restrict where a traditional notary may perform notarial acts and provide only specified exceptions. Illness or inconvenience does not authorize informal notarization by messenger.

What identification is acceptable?

If the affiant is not personally known to the notary, the notary must establish identity through competent evidence of identity. Under the amended 2004 Rules on Notarial Practice, this generally means at least one current identification document that:

Was issued by an official agency; and
Bears the individual’s photograph and signature.

Examples listed in the rules include a passport, driver’s license, PRC ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen card, seaman’s book, government-office ID, and other qualifying government-issued identification.

The controlling test is not simply whether a card is commonly called an “ID.” It must satisfy the rule’s requirements. A company or school ID issued by a private institution is ordinarily insufficient by itself. A community tax certificate or cedula is not competent evidence of identity because it does not provide the photograph-and-signature safeguards required by the rules.

Where documentary identification is unavailable, the rules provide a credible-witness procedure. Depending on whether the witness is personally known to the notary, this may require one or two credible witnesses. Each must personally know the affiant, must not be a party or otherwise privy to the document or transaction, and must satisfy the applicable identification requirements. This is not a shortcut for an expired or forgotten ID; arrange it with the notary beforehand.

Bring the original ID, not only a photograph or photocopy. The notary may ask for additional proof if the name, photograph, signature, age, or other details do not reasonably establish identity.

Signing and notarial-register requirements

For a paper affidavit, do not sign before meeting the notary unless the notary has confirmed that the legally applicable procedure permits it. In a jurat, the affiant signs in the notary’s presence after taking the oath or affirmation.

At the time of notarization, the notary must make the required entry in the notarial register. The entry includes information such as the date and time, type of notarial act, document description, principal’s name and address, identification used, fee charged, and other required circumstances. The principal must sign or affix the appropriate thumbmark or other mark in the register.

Before leaving, inspect the jurat. It should not contain unexplained blanks. It should show the date and place of the notarial act, the affiant’s identification details when required, the notary’s signature and seal, and the relevant commission and document-register particulars.

A notary must not place a signature or seal on an incomplete notarial certificate.

The affidavit must be complete

A notary may not notarize a blank or incomplete document or one without the appropriate notarial certificate. Before the appointment:

Fill in all factual blanks that apply.
Remove unused alternatives or mark them appropriately.
Number the pages.
Check names, dates, addresses, identification numbers, property descriptions, case numbers, and monetary amounts.
Attach and label every exhibit referred to in the affidavit.
Avoid unattached signature pages.
Do not leave space where material statements could later be inserted.
Make sure all pages belong to the same final document.

The notary is not automatically acting as your legal adviser. Notarization does not mean the notary drafted the affidavit, verified the underlying events, approved the transaction, or certified that the document will accomplish its intended legal purpose.

Writing a reliable affidavit

An effective affidavit states facts, not accusations dressed as facts. Use short, chronological paragraphs and identify dates, places, people, documents, and communications as accurately as possible.

Distinguish among:

What you personally saw, heard, did, received, or recorded
Information obtained from a named document
Information another person told you
Conclusions, estimates, suspicions, or opinions

Do not state that something happened “on or about” a date merely to conceal uncertainty. If you cannot recall the exact date, say so honestly and identify the reliable time range or event that anchors your recollection.

Do not include unnecessary sensitive information. An affidavit filed in court or submitted to an agency may become part of an official record. Include complete account numbers, minor children’s details, medical information, home addresses, or identity-document numbers only when required and handle copies securely.

For an affidavit in a language the affiant does not understand, obtain an accurate translation and follow the receiving authority’s rules. A judicial affidavit must be prepared in the language known to the witness; if that language is neither English nor Filipino, it must be accompanied by an English or Filipino translation.

Special rules for judicial affidavits

A judicial affidavit is not simply a general affidavit with a case caption. Under the Judicial Affidavit Rule, it must follow a structured question-and-answer format and contain specified information, including:

The witness’s identifying and contact information
The examining lawyer’s name and address
The place of examination
A statement that the witness answers under oath and understands the possible criminal consequences of false testimony or perjury
Consecutively numbered questions and answers
Identification and authentication of documentary or object evidence
The witness’s signature
A jurat signed by the notary or other officer authorized to administer the oath
The examining lawyer’s separate sworn attestation required by the rule

Judicial affidavits are subject to case-specific filing and service deadlines. Do not assume that ordinary notarization makes a late, incomplete, or noncompliant judicial affidavit admissible. Follow the current court order and procedural rules, and consult counsel promptly if a deadline is near.

Electronic notarization

The Supreme Court has adopted Rules on Electronic Notarization. This does not mean that any online notary, electronic signature application, or video call is legally sufficient.

Under the official framework:

Electronic notarization must use a Supreme Court-accredited Electronic Notarial Facility.
The notary must hold the authority required to perform electronic notarial acts.
Identity verification, electronic appearance, signing, sealing, records, and security must comply with the rules and the accredited facility’s process.
The electronic document and notarial certificate must remain capable of authentication and verification.
Traditional paper documents with wet signatures remain governed by the 2004 Rules on Notarial Practice.

Before paying for an online service, verify it through the Supreme Court’s official eNotary Services portal. A commercial website’s claim that it offers “online notarization” is not, by itself, proof that the resulting affidavit complies with Philippine rules or will be accepted by the intended recipient.

Affidavits signed outside the Philippines

If an affidavit will be signed abroad for use in the Philippines, first ask the Philippine court, agency, bank, registry, or other recipient what form of authentication it requires.

Depending on the country and intended use, the affiant may need to:

Execute the affidavit before a Philippine embassy or consulate; or
Use a competent local notary or other authorized officer and obtain an apostille from the foreign country’s designated authority if the Apostille Convention applies; or
Complete consular authentication where apostille procedures do not apply or an exception requires another process.

An apostille authenticates the origin of the public document or official certificate; it does not establish the truth of the affidavit’s factual statements. Requirements can also vary by document type and destination. Confirm the current instructions with the relevant Philippine embassy or consulate and the receiving office before signing.

For a Philippine-notarized affidavit intended for use abroad, ask the foreign recipient whether it requires a DFA apostille and whether translation, certification, or additional supporting records are needed.

Is there an expiration period?

There is no single expiration period that applies to every affidavit. The affidavit records facts sworn to on a particular date, but a receiving office may require a recently executed document or may reject it when:

Its stated purpose or authorization has ended
The underlying facts have changed
An attached clearance, ID, certificate, or supporting record has expired
A statute, court order, application checklist, or transaction imposes a freshness requirement
It was filed or served after a procedural deadline

Do not assume that a previously notarized affidavit remains usable merely because it has no printed expiration date. Check the current requirements of the recipient.

What notarization does—and does not—prove

Proper notarization gives a private document the evidentiary character associated with a public document as to its due execution and authenticity. It allows courts and the public to rely on the notarial act unless properly challenged.

It does not conclusively prove:

That every factual assertion is correct
That attached documents are genuine
That the affidavit is legally sufficient for its intended purpose
That the affiant has ownership, authority, or capacity not otherwise established
That the transaction described is valid
That a court or agency must accept the affidavit

A defective notarization can strip a document of its public character and reduce it to a private document. In transactions where the law requires a public instrument—not merely proof of a signature—the consequences may be more serious and can affect validity.

False statements and perjury

An affiant must read and understand the entire document before swearing to it. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making a willful and deliberate false statement under oath about a material matter may constitute perjury when the affidavit is made before an authorized officer and is required by law or made for a legal purpose.

The current statutory penalty is prisión mayor in its minimum period, subject to the exact offense, applicable circumstances, and judicial determination. Additional consequences apply when the offender is a public officer or employee, including the statutory fine and disqualification provisions.

Correct an error before signing. If a material mistake is discovered after notarization or filing, do not alter the notarized document by erasure, substitution, or replacement of pages. Preserve the original and promptly ask the recipient or a lawyer whether a corrected, supplemental, or new affidavit must be executed.

Practical checklist

Before notarization

Obtain the recipient’s latest form and checklist.
Confirm the filing deadline and whether the affidavit must be recent.
Verify the exact names and details against official records.
Write only facts you can truthfully swear to.
Gather originals and readable copies of supporting documents.
Label all attachments consistently.
Bring a current government-issued ID bearing your photograph and signature.
Ask about acceptable IDs, copies, witnesses, appointments, and fees.
Leave the signature and jurat for completion through the proper procedure.

During notarization

Appear personally or use the authorized electronic-notarization process.
Present the complete document and original identification.
Tell the notary if you do not understand the language or contents.
Take the oath or affirmation.
Sign where directed.
Sign or mark the notarial register.
Check that the date, place, ID details, seal, signature, and commission information are complete.

After notarization

Scan or photograph every page, including exhibits and the jurat.
Keep the original flat, dry, and secure.
Record when, where, and to whom it was submitted.
Retain filing receipts, acknowledgment emails, courier records, and stamped copies.
Do not detach, replace, or add pages.
Calendar the filing, service, hearing, application, or renewal deadline.

Evidence to preserve if notarization is disputed

Keep:

The complete original affidavit
Copies of all IDs presented
Drafts and messages showing how the affidavit was prepared
Appointment confirmations and payment receipts
Photographs or building records showing the notary’s office
Names and contact details of people present
Submission receipts and certified copies from the receiving office
Any electronic verification data supplied by an accredited facility
A certification from the appropriate court’s notarial section, if later obtained through the proper process

If your signature was forged, your identity was used without permission, or a document was notarized without your appearance, preserve the questioned document and seek legal advice before confronting anyone or surrendering the original.

Common mistakes

Signing before appearing for a jurat
Sending the affidavit through a fixer, secretary, messenger, or relative

Assuming the notary has verified the truth of every statement
Copying a generic online form that does not match the recipient’s rules
Failing to attach a document mentioned in the affidavit
Replacing pages after notarization
Using a scanned signature or ordinary video call without the authorized electronic process
Backdating the affidavit
Swearing to facts known only through rumor
Missing a filing deadline while trying to perfect the document
Assuming an affidavit never expires
Treating an apostille as proof that the contents are true

When legal help is urgent

Consult a Philippine lawyer promptly when:

The affidavit concerns land, inheritance, adoption, custody, criminal accusations, immigration status, corporate authority, a large financial obligation, or waiver of rights.
You are being pressured to sign, do not understand the document, or believe information is false.
A filing, hearing, prescription, appeal, protest, or administrative deadline is close.
A notarized deed, special power of attorney, waiver, settlement, or affidavit appears forged or was executed without personal appearance.
Pages, dates, identification details, registry numbers, or notarial seals appear inconsistent.
The affidavit may expose you or another person to criminal, civil, tax, immigration, employment, or professional consequences.
You must retract or correct a material sworn statement.
The affidavit was executed abroad and its admissibility or authentication is disputed.

Frequently asked questions

Must every affidavit be notarized?

An affidavit must be made under oath or affirmation before a person authorized to administer it. A notary public commonly performs this function, but some laws and proceedings authorize judges, court officers, consular officers, or other officials. Follow the rule governing the particular affidavit.

Can I notarize a document anywhere in the Philippines?

A traditional notary’s authority is tied to the territorial jurisdiction stated in the notarial commission, and the rules generally require notarial acts at the notary’s regular place of work or business, subject to specified exceptions. Verify that the notary is currently commissioned for the relevant city or province.

Is one government ID enough?

The rule generally permits at least one current official-agency ID bearing the holder’s photograph and signature. A notary may reasonably request additional evidence where identity remains uncertain, and a receiving agency may separately require more than one ID.

Can a cedula be used as the only ID?

No. Supreme Court decisions explain that a community tax certificate does not satisfy the photograph-and-signature requirement for competent evidence of identity.

Can someone bring my signed affidavit to the notary?

Not for ordinary paper notarization. The affiant’s personal appearance is essential. Delivery by another person cannot replace appearance, identification, oath-taking, and the required register entry.

Can I sign by thumbmark?

The notarial rules provide procedures for a signature by thumbmark or other mark and for persons physically unable to sign. Do not improvise. Inform the notary in advance so the required witnesses, statements, and register entries can be arranged.

Does notarization make an invalid agreement valid?

Not necessarily. Notarization cannot cure illegality, lack of authority, fraud, incapacity, a defective property description, failure to obtain required consent, or noncompliance with a special statutory form.

How much should notarization cost?

There is no single nationwide price for every affidavit. The fee may depend on the document, number of signers or copies, location, complexity, and authorized electronic facility. Ask for the fee before proceeding and obtain a receipt when appropriate. A suspiciously cheap service does not justify skipping legal requirements.

Can I edit an affidavit after it is notarized?

Do not make material handwritten changes, replace pages, or add attachments after notarization. Execute a corrected or supplemental affidavit through the proper process if necessary.
