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 generally:

State facts truthfully, clearly, and from personal knowledge.
Use the form required for the particular transaction or proceeding.
Bring the complete, unsigned affidavit to a duly commissioned notary public.
Personally appear before the notary.
present competent proof of identity, unless personally known to the notary.
Sign the affidavit and take the oath or affirmation before the notary.
Ensure that the notary completes the jurat, affixes the seal, and enters the act in the notarial register.

A notary cannot lawfully notarize a blank or incomplete document, notarize through an unauthorized video call, or certify that someone appeared when that person was absent. The governing rules are the Supreme Court’s 2004 Rules on Notarial Practice, as amended, together with any special law, court rule, or agency instruction applicable to the affidavit.

Electronic notarization is now recognized under the Supreme Court’s Rules on Electronic Notarization, but it must be performed by a separately commissioned Electronic Notary Public through a Supreme Court-accredited facility. An ordinary video call with a traditional notary is not electronic notarization.

What an affidavit should contain

There is no single mandatory format for every affidavit. The contents depend on its purpose—for example, an affidavit of loss, complaint-affidavit, affidavit of discrepancy, affidavit of support, or judicial affidavit.

A properly prepared affidavit ordinarily contains:

The place or territorial heading, such as “Republic of the Philippines” and the relevant city or province.
The affidavit’s descriptive title.
The affiant’s full legal name and identifying details relevant to the transaction.
A statement that the affiant is executing the document under oath.
Separately numbered factual paragraphs.
Identification of any attached records or exhibits.
A statement explaining the affidavit’s purpose.
The affiant’s signature over the printed name.
A jurat completed by the notary or another officer authorized to administer oaths.

Use the name shown on your identification. If different names or spellings appear in your records, explain the discrepancy accurately and attach supporting documents instead of silently choosing one version.

State only facts that you personally know. If information came from records or another person, identify that source. Avoid legal conclusions, exaggeration, accusations unsupported by facts, and statements copied from a template that do not apply to you.

Jurat versus acknowledgment

An affidavit normally requires a jurat. In a jurat, the notary certifies that the affiant personally appeared, signed the document in the notary’s presence, and swore or affirmed that its contents were true.

An acknowledgment serves a different purpose. The signer personally appears and declares that an existing signature was voluntarily affixed and that the document is the signer’s free act and deed. Acknowledgments are commonly used for deeds, contracts, and powers of attorney.

The Supreme Court has repeatedly emphasized this distinction. For a jurat, the affidavit must be signed and sworn to before the notary; an acknowledgment cannot automatically substitute for the required oath. See Dela Cruz v. Dimaano and Limos v. Atty. Odones.

Do not select the notarial certificate merely because a template uses it. The receiving court, agency, bank, school, employer, or foreign authority may require a specific form.

Personal appearance is mandatory

For traditional notarization, the affiant must physically appear before the notary at the time of the notarial act. Leaving an affidavit with a staff member, sending only a scanned signature, or appearing through an ordinary messaging or videoconferencing application does not satisfy the 2004 Rules.

Personal appearance allows the notary to:

Verify the affiant’s identity.
Confirm that the affiant is the person signing.
Administer the oath or affirmation.
Check that the act is voluntary.
Assess whether the affiant understands the document.
Record the transaction in the notarial register.

The Supreme Court treats notarization as an act of substantial public interest, not a clerical formality. A document improperly notarized may lose its character as a public document and be treated as a private document whose due execution and authenticity must be proved. See Dela Cruz v. Dimaano and Kiener v. Amores.

Acceptable proof of identity

If the notary does not personally know the affiant, the affiant must present competent evidence of identity. Under the amended notarial rules, this generally means at least one current identification document that:

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

Examples recognized in the rules include a passport, driver’s license, PRC ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen ID, seaman’s book, alien certificate of registration, and other qualifying official identification.

The issuing agency or receiving institution may impose stricter requirements, such as requesting two IDs or photocopies. Call ahead if the transaction is urgent.

A community tax certificate or cedula alone is not competent evidence of identity because it does not bear both the photograph and signature required by the rules. The Supreme Court applied this rule in Heir of Unite v. Guzman.

If an affiant lacks a qualifying ID, identification may be established through credible witnesses under the conditions in the notarial rules:

One credible witness who personally knows both the affiant and the notary; or
Two credible witnesses who personally know the affiant and present their own qualifying identification.

A credible witness must not be a party to, or privately interested in, the document or transaction. This is not simply an invitation to bring any two companions; the relationships and identification requirements matter.

The document must be complete

A notary must not notarize a blank or incomplete instrument. Before appearing, check that:

All factual paragraphs are complete.
Names, addresses, dates, amounts, and reference numbers are correct.
Blank spaces that could alter the meaning have been completed or properly addressed.
All pages and attachments are present.
Exhibits are identified consistently in the affidavit.
Corrections are visible and properly initialed if the notary or receiving office permits them.
The jurat has enough space for the notarial details.

Do not ask the notary to notarize a signature page separated from the rest of the affidavit. Do not add, remove, or replace pages after notarization. A material change may require a new affidavit and a new notarial act.

Language, understanding, and voluntary execution

Read the entire affidavit before taking the oath. Tell the notary if you:

Do not understand the language used.
Cannot read the document.
Need an interpreter.
Have difficulty signing.
Are being pressured to sign.
Believe a material fact or attachment is missing.

The document should be written in a language the affiant understands or reliably explained and translated. Special procedures may be necessary for an affiant who signs by mark, has a disability, or requires an interpreter. The arrangement should be discussed with the notary in advance and documented carefully.

Never sign merely because someone says the affidavit is “standard.” The affiant—not the person who prepared the document—is responsible for the sworn statements.

Traditional notarization: practical steps

1. Confirm the exact requirement

Ask the receiving office for its current checklist or prescribed form. Determine:

The required type of affidavit.
Whether a particular statement or undertaking must be included.
Which attachments are required.
Whether the office requires an original, certified copy, or multiple notarized copies.
Whether it imposes a submission deadline or a maximum age for the affidavit.
Whether it accepts electronic notarization.
Whether a document for foreign use must be apostilled.

There is no universal validity period for all affidavits. A receiving office may nevertheless require one executed within a particular period, while changed circumstances can make an older affidavit inaccurate.

2. Prepare the facts and supporting records

Create a factual timeline and collect the records supporting each material statement. Use exact dates where known. If an exact date is genuinely unknown, say so rather than guessing.

3. Bring the complete affidavit and identification

Unless the notary instructs otherwise, bring:

The complete unsigned affidavit.
All attachments.
The original qualifying ID or IDs.
Any requested photocopies.
Proof of authority if signing in a representative capacity.
Any special agency form or written checklist.

For a jurat, do not sign in advance. The affiant must sign and take the oath in the notary’s presence.

4. Appear before a properly commissioned notary

Check the notary’s current commission and territorial authority. Traditional notarial authority is geographically limited; a notary cannot rely on a commission for one territorial jurisdiction to notarize anywhere in the country.

5. Review the completed jurat

Before leaving, check that the jurat and seal are legible and that the certificate states the date and place of notarization. Traditional notarial certificates ordinarily include the document, page, book, and series details, together with information identifying the notary’s commission.

Keep the official receipt when one is issued. Notarial fees are not subject to one universal private-practice price for every document; complexity, number of signers, and lawful local arrangements may affect the charge. Ask for the fee before proceeding.

Electronic notarization

The Rules on Electronic Notarization supplement rather than replace traditional notarization.

An electronic affidavit may be notarized electronically only when:

The document is in PDF or PDF/A form.
The notary holds a valid electronic notarial commission.
A Supreme Court-accredited Electronic Notarization Facility is used.
Identity, location, appearance, signing, and recordkeeping requirements are satisfied.
The transaction is one permitted by the rules.

The permitted modes include:

In-person electronic notarization, where the participants physically appear but use the electronic facility.
Remote electronic notarization, where participants appear simultaneously by videoconference through the accredited facility.
A combination of the two modes when allowed.

For an electronic jurat, the affiant should not electronically sign before the notarial session. The electronic signature must be placed in the Electronic Notary Public’s presence. Electronically notarized documents have the same legal force as traditional notarial acts when all governing requirements are followed.

As of the source check date below, the Supreme Court had opened electronic-notary commissioning processes, but its public-facing site indicated that an Electronic Notary Public directory would be made available. Availability may therefore depend on commissioned notaries and accredited facilities. Verify current access through the Supreme Court’s Electronic Notary Services portal and official electronic-notarization FAQ.

A traditional notary is not automatically an Electronic Notary Public. A document notarized remotely through an unaccredited platform does not become valid electronic notarization merely because the participants recorded a video call.

A person located abroad may use remote electronic notarization only under the special conditions in the rules, including being within a Philippine embassy, consular office, or office of a Philippine honorary consul while an authorized officer confirms the person’s presence. Local law and operational limitations in the foreign country may prevent this option.

Affidavits executed abroad

The procedure depends on where the affidavit will be used and where it is signed.

Common routes include:

Execution before a Philippine embassy or consulate offering the relevant notarial service.
Notarization before a competent local notary, followed by an Apostille issued by the competent authority of a country that is party to the Apostille Convention.
Authentication or legalization under the applicable process when the Apostille Convention does not apply.
Compliant remote electronic notarization under the Philippine rules, when operationally available and all extraterritorial conditions are satisfied.

An Apostille authenticates the origin of a public document—such as the signature, capacity of the signer, and seal—not the truth of the affidavit’s factual statements.

Country-specific requirements, appointments, fees, and accepted identification vary. Consult the relevant Philippine foreign service post and the DFA’s Apostille information page before signing or paying a service provider.

Special affidavits may have additional rules

General notarization requirements do not replace special substantive or procedural requirements.

Judicial affidavits

A judicial affidavit used as testimony in covered court proceedings must comply with the Judicial Affidavit Rule. Among other requirements, it must use consecutively numbered questions and answers, identify how the witness learned the facts, identify and authenticate exhibits, contain prescribed information about the witness and examining lawyer, and carry the proper jurat.

Court deadlines are case-specific. Failure to submit a required judicial affidavit and exhibits on time may result in waiver, subject to the limited relief allowed by the rule.

Complaint-affidavits and counter-affidavits

Prosecutors, law-enforcement bodies, and administrative agencies may prescribe their own forms, copy requirements, filing channels, and deadlines. Notarization alone does not make a late or incomplete submission sufficient.

Affidavits involving property, authority, or family matters

Affidavits concerning estate settlement, land, corporate authority, guardianship, travel consent, financial support, or civil-registry corrections may require additional parties, documentary proof, publication, registration, or a court or agency proceeding. An affidavit cannot create a right or cure a defective transaction when the law requires more.

What notarization does—and does not do

Proper notarization gives the notarial act its public character and supports proof of due execution and authenticity. It does not:

Prove that every factual allegation in the affidavit is true.
Transfer ownership merely because a document bears a seal.
Cure fraud, forgery, lack of consent, lack of authority, or illegality.
Replace registration, filing, publication, witnessing, or approval required by law.
Guarantee that a court or agency will accept the affidavit.
Prevent the statements from being challenged with competent evidence.

A defective notarization commonly strips the document of its public character and reduces it to a private document requiring proof of due execution and authenticity. Whether the underlying transaction remains valid is a separate question governed by the applicable law and facts.

Evidence to preserve

Keep a secure copy of:

The final notarized affidavit, including every page.
All exhibits exactly as submitted.
The IDs presented, subject to safe handling of personal information.
The notary’s name, office address, commission details, and official receipt.
Submission receipts, email acknowledgments, courier records, and tracking numbers.
The receiving office’s checklist or written instructions.
Any rejection notice or request for correction.
For approved electronic notarization, the original electronically notarized file—not merely a printed copy or screenshot—and any available verification data or audiovisual recording requested through the facility.
For foreign documents, the Apostille, authentication certificate, or consular record.

Preserve the original electronic file because printing it may not retain all digital signatures, certificates, and tamper-verification features.

Common mistakes

Signing a paper affidavit before meeting the notary.
Sending another person to have the affidavit notarized.
Treating a cedula as sufficient identification.
Using an expired, damaged, or mismatched ID.
Leaving material blanks in the document.
Attaching exhibits after notarization without identifying them in the affidavit.
Using an acknowledgment where a jurat is required.
Copying facts from an online template without checking whether they are true.
Asking a notary to backdate the certificate.
Accepting notarization performed only through an ordinary video call.
Assuming every notarized affidavit remains acceptable indefinitely.
Believing notarization automatically proves the truth of the statements.
Altering the document after it has been notarized.
Missing the separate filing deadline because the affidavit was notarized on time.
Using a relative as notary without checking the disqualification rules.

Under the 2004 Rules, a notary is disqualified when the notary is a party to the document, has a prohibited interest in it, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

False statements and perjury

Do not swear to facts you know are false. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making a material, untruthful statement under oath before a competent officer in a case where the law requires the oath may constitute perjury.

Criminal liability is not established merely because another person disputes the affidavit. The prosecution must prove the statutory elements, including a willful and deliberate falsehood concerning a material matter. Still, any known error should be addressed promptly through the procedure appropriate to the receiving office or pending case. Do not secretly alter an already notarized affidavit.

When legal help is urgent

Consult a Philippine lawyer promptly when:

You are asked to sign facts you cannot verify.
The affidavit concerns a criminal complaint, counter-affidavit, arrest, subpoena, or prosecutor’s deadline.
A court filing or hearing deadline is approaching.
The affidavit concerns land, inheritance, substantial money, corporate authority, immigration, custody, or domestic violence.
Someone denies signing or appearing before the notary.
A signature, seal, ID, or notarial entry may be forged.
Pages were added, removed, or changed after notarization.
You signed under threat, deception, or without understanding the document.
An affidavit already filed contains a material mistake.
A foreign authority rejected the document or requires an Apostille.
A government office rejected the affidavit and the time to appeal or correct it is limited.

If personal safety is at risk, contact law enforcement, the appropriate protective service, or emergency assistance rather than waiting to complete an affidavit.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily a sworn statement and therefore requires a jurat administered by a notary or another officer legally authorized to administer oaths. Some laws or procedures permit unsworn declarations or certifications in defined circumstances, but those are exceptions. Follow the rule governing the particular submission.

Can I sign the affidavit before going to the notary?

For a traditional jurat, no. Sign in the notary’s presence after the notary verifies your identity and administers the oath or affirmation. An acknowledgment follows different signing rules, but it is not normally the correct certificate for an affidavit.

Do I need two government IDs?

The notarial rules generally refer to at least one current official ID bearing the affiant’s photograph and signature. A notary or receiving institution may reasonably ask for additional identification or photocopies, particularly when identity details do not match.

Is a barangay ID or certification always acceptable?

Only if the particular document satisfies the rules’ requirements, including official issuance and the required identifying features. Because formats vary, bring a passport, driver’s license, or another clearly qualifying photo-and-signature government ID when available.

Can a notary prepare the affidavit for me?

A lawyer may provide drafting services separately from the notarial act. Notarization itself does not mean the notary investigated the facts or gave legal advice. For a contested or high-value matter, obtain independent legal advice before signing.

Can one affidavit cover several people?

Possibly, if the required form permits it and each affiant can personally swear to the relevant facts. Every affiant must properly appear, be identified, sign, and take the oath. Separate affidavits may be clearer when the affiants know different facts.

Can I notarize a scanned affidavit online?

Only through the formal electronic-notarization system, using a commissioned Electronic Notary Public and a Supreme Court-accredited facility. Emailing a scan to a traditional notary or joining an ordinary video call is insufficient.

Does a notarized affidavit expire?

There is no single expiration rule for every affidavit. Its continued usefulness depends on its contents and the receiving authority’s rules. An affidavit may become inaccurate when circumstances change, and an agency may require one executed within a stated period.

Can an affidavit be corrected after notarization?

Do not alter the notarized document. For a material error, the safer course is generally to execute a corrected or supplemental affidavit, disclose the correction, and follow the receiving authority’s instructions.

Does notarization make the affidavit conclusive evidence?

No. Proper notarization authenticates the notarial act and supports due execution; it does not make every factual statement indisputably true. Courts and agencies may test the statements against testimony and other evidence.
