Quick answer

A Philippine affidavit is ordinarily valid as a sworn statement only when the affiant:

states facts truthfully and, as far as possible, from personal knowledge;
appears personally before a duly commissioned notary public or another officer legally authorized to administer the oath;
presents the complete affidavit and competent proof of identity;
signs the affidavit in the notary’s presence; and
actually takes an oath or affirmation.

The notary must complete a jurat, sign and seal it, record the act in the notarial register, and require the affiant to sign or place a mark in that register. A representative cannot appear or swear in place of the named affiant.

For a paper affidavit with a handwritten signature, physical appearance remains the general rule. Remote notarization is permitted only for eligible electronic documents through a commissioned Electronic Notary Public and a Supreme Court-accredited electronic notarization facility—not through an ordinary video call or by emailing a signed scan.

What an affidavit legally does

An affidavit, also called a sinumpaang salaysay or sworn statement, is a written declaration made under oath. It commonly supports applications, complaints, claims, explanations, reports of loss, proof of identity or relationship, and court or administrative proceedings.

The affiant is responsible for the statements. Notarization confirms the administration of the oath, the affiant’s identity, appearance, signature, and the regularity of the notarial act. It does not mean that the notary investigated every allegation or guaranteed that the contents are true.

The Supreme Court has clarified that notarized documents are generally prima facie evidence of due execution and authenticity—not automatically of the truth of every statement they contain. An affidavit may still be hearsay in a trial if the affiant is not presented for examination, unless a rule or recognized exception permits its use. See Anido v. Republic, G.R. No. 253527, October 21, 2024.

Jurat versus acknowledgment

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

Notarial act	What the signer does	Common use
Jurat	Personally appears, signs in the notary’s presence, and swears or affirms that the contents are true	Affidavits, sworn statements, verified declarations
Acknowledgment	Personally appears and declares that an integrally complete document was signed voluntarily as the person’s act and deed, including any claimed representative authority	Deeds, contracts, powers of attorney and similar instruments

A certificate saying only “acknowledged before me” may not satisfy a requirement that an affidavit be “subscribed and sworn.” The correct certificate depends on the document and the law or agency requiring it.

Requirements for a paper affidavit

1. A complete and accurate document

The affidavit should contain:

the affiant’s complete name and relevant personal circumstances;
a clear, numbered narration of material facts;
dates, places, names and amounts when relevant;
an explanation of how the affiant knows each important fact;
the purpose for which the affidavit is executed;
properly identified attachments, if any; and
a signature block followed by a jurat.

The venue in the heading and jurat should reflect the place where the oath is actually administered. Do not leave material blanks for later completion. Use “N/A” where appropriate if the prescribed form permits it.

A notary must not notarize a blank or incomplete document, attach a seal to an incomplete certificate, or knowingly certify false information. The notary must also refuse when the transaction appears unlawful or immoral, the signer does not appear to understand its consequences, or the signer may be acting under coercion.

2. Personal appearance

The affiant must be physically present before the traditional notary when a paper affidavit is notarized. The affiant must sign in the notary’s presence and take the oath or affirmation.

The following shortcuts are not valid compliance:

sending a relative, employee or liaison in the affiant’s place;
leaving a signed affidavit and identification card with a notarial office;
having the notary sign and seal the document later without meeting the affiant;
obtaining a notarial seal through an ordinary video call; or
asking for an earlier date to be placed on the jurat.

Traditional notarial acts are ordinarily performed at the notary’s regular place of work within the territorial jurisdiction of the commissioning court. Limited off-site notarization is allowed within that jurisdiction in specified settings, including certain public functions, hospitals and places of detention.

3. Competent proof of identity

Unless the affiant is personally known to the notary, the general rule requires at least one current identification document issued by an official agency that bears the affiant’s photograph and signature. Examples recognized in the rules include passports, driver’s licences, PRC IDs, SSS or GSIS cards, senior-citizen IDs, seafarer’s books and other qualifying government-issued identification.

A community tax certificate or cedula alone is not competent evidence of identity because it does not contain the required photograph and signature. The Supreme Court applied this rule in Heirs of Torrices v. Gala, A.C. No. 12062, July 4, 2018.

Although the notarial rule says “at least one,” a notary or receiving agency may reasonably ask for another ID or supporting document where names differ, an ID lacks a signature, its authenticity is doubtful, or a special procedure imposes additional requirements.

If suitable identification is genuinely unavailable, identity may be established through credible witnesses:

one credible witness who is personally known to the notary, personally knows the affiant and is not involved in the transaction; or
two credible witnesses who personally know the affiant, are not involved in the transaction and present documentary identification to the notary.

This is a controlled alternative, not a way to bypass ordinary identity checks.

4. Signature and oath

For a jurat, the affiant signs before the notary and expressly swears or affirms that the affidavit is true. An affirmation may be used instead of a religious oath.

Each named affiant must separately appear, be identified, sign and take the oath. A corporate officer or representative may swear only as the actual affiant and should state the source of personal or records-based knowledge and show authority when the transaction or receiving office requires it.

A person who uses a thumbmark or another mark must place it before the notary and two disinterested, unaffected witnesses, who must also sign. The rules also provide a carefully documented procedure when a person is physically unable to sign or make a mark; this requires the person’s direction, the notary and two disinterested witnesses. It should be arranged with the notary in advance.

5. A complete jurat and notarial record

Before leaving, check that the jurat contains or is accompanied by:

the actual date and place of notarization;
language showing that the affidavit was subscribed and sworn or affirmed;
the affiant’s identity information or a statement that the affiant is personally known to the notary;
the notary’s signature and official seal;
the notary’s name, commission number, territorial commission and expiration;
the notary’s office address and required professional details; and
the document, page, book and series numbers corresponding to the notarial register.

The affiant should also have signed or placed the appropriate mark in the notarial register. Missing identity information, blank register details, an expired commission or an unrecorded act can cast serious doubt on the notarization.

Not every lawyer is automatically a notary public. A lawyer must hold a valid notarial commission for the relevant territorial jurisdiction.

A practical preparation checklist

Before going to the notary

Obtain the current form or checklist directly from the court, bank, school, employer or government agency that will receive it.
Confirm the filing deadline and whether supporting documents must be certified, original, recent or attached as annexes.
Review every statement, name, date, address, amount and document number.
Remove unresolved blanks.
Bring the unsigned final affidavit for a paper jurat.
Bring at least one current government-issued ID with both photograph and signature; bringing a second ID is prudent.
Bring originals and copies of supporting documents.
If signing for an organization, bring the board resolution, secretary’s certificate, authority letter or other required proof of authority.
If the affiant needs an interpreter, accessibility accommodation, witnesses or hospital notarization, arrange this before the appointment.

During notarization

Meet the notary personally.
Confirm that the document shown to the notary is the final version.
Ask questions if any statement or legal effect is unclear.
Sign only when directed.
Take the oath or affirmation.
Sign the notarial register and verify that the entry describes the correct document.
Ask for an official receipt and clarify whether any separate charge is for drafting, legal advice, travel, copies or another service.

After notarization

Check the jurat, seal, commission details and register numbers before leaving.
Scan the complete affidavit in colour, including every attachment and the jurat.
Preserve the original in a dry, secure place.
Submit it through the channel required by the receiving office.
Keep the submission receipt, email confirmation, tracking number or stamped receiving copy.
Do not insert pages, alter material text or replace attachments after notarization.

Deadlines, validity and “expiry”

There is no single nationwide filing deadline or universal expiration period for all affidavits. The deadline comes from the transaction, statute, court rule, order or agency procedure for which the affidavit is required.

An affidavit also does not automatically become invalid after a fixed number of months. However:

the receiving office may require a recently executed affidavit;
the facts may become outdated;
an ID or supporting certificate may expire;
a court order may set a strict filing or service period; or
a special affidavit may have a prescribed form and timing requirement.

Notarization does not extend a filing deadline. If time has already expired, do not backdate the affidavit; promptly ask the receiving office or a lawyer whether late filing, an extension, substantial compliance or another remedy remains available.

Judicial affidavits, complaint-affidavits, affidavits of desistance, affidavits involving land, immigration, family status or estate matters may be governed by additional rules. An ordinary template should not be assumed sufficient for these purposes.

Corrections and replacement affidavits

Correct mistakes before signing and taking the oath. If a material error is discovered after notarization, the safest practice is ordinarily to prepare a corrected or supplemental affidavit, appear again, sign it under oath and clearly identify what is being corrected.

Do not:

erase or cover material text in a notarized affidavit;
replace a signed page;
add an attachment that the notary did not see;
change the date or venue; or
ask the notary to issue a replacement bearing the original date.

Whether a corrected affidavit can still be filed depends on the governing deadline and the receiving office’s rules.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement rather than replace traditional notarization.

An electronic affidavit in PDF or PDF/A format may be notarized by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. The rules provide two modes:

In-Person Electronic Notarization: the parties physically appear before the Electronic Notary Public and use the accredited facility.
Remote Electronic Notarization: the parties appear through the facility’s live videoconferencing, identity-verification and location-verification functions.

For an electronic jurat, the affiant must apply an electronic signature through the facility in the Electronic Notary Public’s full view and take the oath. An ordinary e-signature platform, recorded video, emailed scan or private Zoom session does not by itself meet these requirements.

Paper documents bearing wet signatures remain governed by the traditional rules. Notarial wills, depositions and paper instruments are excluded from the electronic-notarization framework. The Supreme Court’s current guidance is available through its Electronic Notary Services FAQ.

Affidavits signed abroad

A person abroad should first ask the Philippine receiving office which route it accepts. Common lawful routes include:

appearing before a Philippine embassy or consulate for a consular jurat;
signing before an authorized local notary and obtaining an Apostille when the country and document fall under the Apostille Convention; or
following the applicable authentication or legalization process for a non-Apostille country.

An Apostille authenticates the origin of the public document—such as the signature, official capacity and seal—not the truth of the affidavit’s contents. Requirements vary by country and document, so consult the relevant Philippine foreign-service post and the DFA Apostille guidance.

Under the electronic-notarization rules, limited remote notarization from abroad is possible only while the principal is within a Philippine embassy, consular office or office of a Philippine honorary consul, with a designated officer confirming the person’s presence. A person simply joining from a home or workplace abroad does not qualify for this exception.

Common mistakes to avoid

Using an acknowledgment when the document requires a jurat.
Signing a paper affidavit before meeting the notary.
Allowing another person to appear for the affiant.
Relying on a cedula alone as identification.
Leaving names, dates, amounts, ID details or other material fields blank.
Copying an internet template without checking the receiving office’s current form.
Using a notary whose commission is expired or whose territorial authority does not cover the place of notarization.
Accepting “online notarization” of a wet-signed scan outside an accredited electronic facility.
Signing facts supplied by someone else without confirming them.
Stating conclusions as personal knowledge when they came only from rumours or unidentified sources.
Altering pages or annexes after the notarial act.
Assuming notarization makes an illegal transaction valid or proves every allegation.

Evidence to preserve

Keep:

the complete original affidavit and a clear colour scan;
the exact final draft or electronic file that was signed;
all attachments as presented during notarization;
the notary’s receipt and contact details;
photographs or scans showing the seal, jurat and register numbers;
submission receipts, courier records and email confirmations;
communications showing who prepared, requested or transmitted the affidavit;
documents supporting each material statement; and
the names of people present during signing.

If a disputed document appears to bear your signature or claims that you appeared before a notary when you did not, preserve the document without writing on it. Ask the Office of the Clerk of Court or Executive Judge of the Regional Trial Court identified in the certificate to confirm the notary’s commission and the relevant notarial record. Obtain legal advice before making accusations, surrendering the original or signing a supposed “cancellation.”

Consequences of false or defective affidavits

A knowingly false statement on a material matter may constitute perjury when the legal elements are established. Republic Act No. 11594 increased the statutory penalty under Article 183 of the Revised Penal Code to prisión mayor in its minimum period—six years and one day to eight years—together with a fine of up to ₱1 million and the disqualification provided by law. A public officer or employee is subject to the maximum period specified in the statute.

An honest error, unclear recollection or immaterial discrepancy is not automatically perjury; the law requires a knowing falsehood on a material matter. Nevertheless, an error should be corrected promptly and transparently.

Defective notarization may cause a document to lose the evidentiary benefits of a regularly notarized instrument and be treated as a private or unsworn document. Whether the underlying act remains valid depends on the governing law. For transactions where a public instrument is required for validity—not merely for evidence—a defect can have more serious consequences.

The notary may also face revocation of the commission, disqualification from future commissioning, professional discipline and, in appropriate cases, civil or criminal liability.

When legal help is urgent

Consult a Philippine lawyer promptly if:

the affidavit concerns a criminal complaint, arrest, subpoena or prosecutor’s deadline;
it transfers or gives up land, inheritance, custody, support, money or another substantial right;
someone is pressuring you to sign, conceal facts or use an earlier date;
you do not understand the affidavit’s language or legal effect;
your signature was forged or a document falsely states that you personally appeared;
material pages were inserted, removed or altered after signing;
the affiant may lack capacity or is seriously ill;
an adverse affidavit has already been filed against you;
a deadline is about to expire; or
a government agency or court has rejected the document.

Do not sign merely because the document is described as “standard,” “for formality only” or “just notarization.” Ask for a copy, read it fully and obtain independent advice when rights or liabilities are involved.

Frequently asked questions

Do I always need two valid IDs?

No. The general traditional rule requires at least one current official identification document bearing both photograph and signature, unless the affiant is personally known to the notary or the credible-witness procedure applies. A notary or receiving agency may require additional identification in a particular case.

Is a cedula enough?

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

May I sign before visiting the notary?

Not for a paper affidavit requiring a jurat. The affiant must sign in the notary’s presence and take the oath. If it was signed beforehand, ask the notary whether a clean copy or a new signature is required.

Can my representative have my affidavit notarized?

No. The named affiant must personally appear, be identified, sign and take the oath. Authority to transact for someone does not ordinarily permit the representative to swear that the principal personally made the affidavit.

Can an affidavit be notarized online?

Yes, but only when it is an eligible PDF or PDF/A electronic document processed by a commissioned Electronic Notary Public through an accredited Electronic Notarization Facility. A remotely notarized wet-signed scan or informal video call is not sufficient.

Does notarization prove that every statement is true?

No. It authenticates the notarial act and due execution. The affiant remains responsible for the truth of the contents, and a court or agency may still require supporting evidence or testimony.

Does an affidavit expire?

There is no universal expiration period. The receiving office may require a recent affidavit, and the facts or supporting documents may become outdated.

Is an unnotarized affidavit useless?

Not necessarily, but it is ordinarily not a sworn affidavit. It may operate as a private written statement if the applicable law or procedure accepts it. If an oath or notarization is expressly required, the omission may lead to rejection or require correction.

Can any government officer administer the oath?

Several officials have statutory authority to administer oaths, but many may do so only in connection with official business or a matter within their functions. Follow the particular court or agency’s instructions. A private lawyer who lacks a valid notarial commission cannot act as a notary merely because the person is a lawyer.

How can I check a suspicious notarization?

Verify the notary’s commission with the Office of the Clerk of Court or Executive Judge of the Regional Trial Court identified in the certificate. Request inspection or a certified record where permitted, and compare the document, date, parties and register numbers. Seek legal advice if the entry is missing or inconsistent.
