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 generally must:

State facts truthfully, preferably from personal knowledge.
present the complete affidavit to a duly commissioned notary public;
personally appear before the notary;
prove identity through acceptable evidence unless personally known to the notary;
sign the affidavit in the notary’s presence; and
take an oath or affirmation that its contents are true.

The notary then completes the jurat, records the act in the notarial register, and affixes the required signature, seal, and commission details. Leaving a signed affidavit with an office for later notarization, signing through a representative, or appearing only through an ordinary video call does not satisfy the rules for paper notarization.

Electronic notarization is separately permitted under the Supreme Court’s 2025 Rules on Electronic Notarization. It must be performed by a duly commissioned electronic notary public through the authorized electronic-notarization process—not through an informal video call or by simply pasting a scanned signature and seal onto a PDF.

What an affidavit should contain

There is no single universal affidavit form. The required allegations and attachments depend on its purpose, such as an affidavit of loss, complaint-affidavit, affidavit of support, affidavit of service, or affidavit required by a court or government agency.

A properly prepared affidavit ordinarily contains:

A venue showing the country and city or province where the oath is administered.
The affiant’s full name and relevant personal details, such as age, civil status, citizenship, and address, when required.
A statement that the affiant is executing the document under oath.
Clear, consecutively numbered factual statements.
An explanation of how the affiant knows each material fact.
Identification of supporting documents, photographs, messages, receipts, or other attachments.
A statement explaining the affidavit’s purpose.
The affiant’s signature.
A jurat completed by the notary or other officer authorized to administer oaths.

Use the exact form prescribed by the receiving court, agency, school, bank, insurer, employer, or foreign authority when one exists. A technically notarized affidavit can still be rejected if it omits information, wording, attachments, witnesses, or certifications required for the particular transaction.

Jurat versus acknowledgment

An affidavit normally requires a jurat. Under the notarial rules, the affiant:

personally appears before the notary;
presents the document;
is personally known to the notary or properly identified;
signs in the notary’s presence; and
takes an oath or affirmation concerning the document.

An acknowledgment serves a different purpose. The signer personally appears and declares that an existing signature was voluntarily placed on the document and that the document is the signer’s free act and deed. Deeds, contracts, and instruments conveying rights commonly use acknowledgments rather than jurats.

The certificate should match the nature of the document. The Supreme Court has disciplined notaries for confusing a jurat with an acknowledgment. A deed that legally requires acknowledgment should not be converted into an affidavit merely by attaching a jurat.

Personal appearance is mandatory for paper affidavits

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

verify that the person appearing is the affiant;
compare the person with the identification presented;
witness the signing;
administer the oath or affirmation;
assess whether the affiant understands the act; and
determine whether the act is voluntary.

The following practices are improper:

Sending an already signed affidavit through a messenger.
Asking another person to appear for the affiant.
Leaving the affidavit at a notarial office for later signing or sealing.
Backdating the jurat.
Notarizing a blank or incomplete document.
Using a photocopy of another person’s signature.
Treating a telephone call or ordinary online meeting as personal appearance for paper notarization.

The Supreme Court has repeatedly emphasized that notarization is not an empty formality. See the 2004 Rules on Notarial Practice and the Court’s discussion of personal appearance in Bides v. Salazar, A.C. No. 7297.

Acceptable proof of identity

Unless the affiant is personally known to the notary, identity must be established through competent evidence.

The principal method is at least one current identification document issued by an official agency and bearing the holder’s photograph and signature. The rules give examples such as a passport, driver’s license, PRC ID, government office ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen ID, and other qualifying government-issued documents.

A company, school, association, or other privately issued ID ordinarily does not satisfy this rule by itself. A Community Tax Certificate or cedula should not be assumed to be sufficient proof of identity.

If the affiant lacks qualifying identification, the rules allow identification through credible witnesses under strict conditions:

One credible witness who is personally known to the notary and personally knows the affiant; or
Two credible witnesses who personally know the affiant and present qualifying documentary identification.

A credible identifying witness must not be a party to, or otherwise privy to, the instrument, document, or transaction. The precise arrangement should be confirmed with the notary beforehand.

The governing identity rule appears in the Supreme Court’s February 19, 2008 amendment to the 2004 Notarial Rules.

Prepare the document before visiting the notary

A notary should refuse to notarize an incomplete instrument. Before appearing:

Obtain the correct form from the intended recipient.
Check all names against official IDs and supporting records.
Complete every material blank; write “N/A” where appropriate.
Use exact dates, places, reference numbers, and document descriptions.
Number the paragraphs and pages.
Mark and securely attach supporting exhibits.
Correct errors before signing instead of using unexplained erasures.
Bring the original qualifying ID and any copies the office requests.
Bring all affiants if the document is joint.
Do not sign until the notary instructs you to do so.

Read every paragraph carefully. If a statement is based on records rather than direct observation, identify the records and avoid presenting an inference as personal knowledge. Do not sign a template containing facts that do not apply to you.

What the notary must check and record

A duly commissioned notary must generally:

Confirm that the document is complete.
Require the affiant’s personal appearance.
establish identity through personal knowledge or competent evidence;
witness the signature or permitted mark;
administer the oath or affirmation;
record the act in the notarial register;
require the appropriate register signature or thumbmark;
complete the jurat accurately; and
affix the official signature and seal together with the required commission and professional details.

The affidavit should receive a document number, page number, book number, and series corresponding to the notarial register. Check that the jurat states the correct date and place and identifies the evidence of identity or indicates that the affiant is personally known to the notary, as applicable.

The notary ordinarily acts within the territorial jurisdiction of the commission and from the regular place of work or business, subject to the limited circumstances permitted by the rules. A notary may also be disqualified by a direct financial or beneficial interest or by a prohibited relationship to a principal.

The Supreme Court amended the paper-notarization rules in 2025 to strengthen electronic recordkeeping, reporting, and safeguards. The current consolidated text is available in the Amended 2004 Notarial Rules.

Electronic and remote notarization

The 2025 Rules on Electronic Notarization govern electronic documents and electronic notarial acts. They recognize:

In-person electronic notarization, in which the principal and electronic notary are physically together; and
Remote electronic notarization, in which appearance and identity verification occur through the prescribed secure electronic process.

These rules do not authorize every notary to notarize remotely. The act must be handled by a lawyer holding the appropriate electronic notarial commission and must comply with the Supreme Court’s platform, identity, signing, recording, certificate, and retention requirements.

Do not email a signed PDF to an ordinary notary and assume that a video call will make it valid. Confirm that the lawyer is authorized to perform the particular electronic act and that the receiving institution accepts electronically notarized documents. Paper affidavits with wet signatures remain governed by the paper-notarization rules.

Current implementation information is available through the Supreme Court’s Electronic Notarization Services FAQs.

Special situations

Affiant cannot sign normally

A thumbmark or other mark may be used when properly witnessed and recorded. The rules also provide a tightly controlled procedure for a notary to sign on behalf of a person who is physically unable to sign or make a mark. It requires the person’s direction, two disinterested witnesses, prescribed wording, and the required notarial act.

Tell the notary about the disability before the appointment so the correct witnesses and procedure can be arranged. No one should casually sign another person’s affidavit under a special power of attorney because an affidavit ordinarily concerns the affiant’s own oath and knowledge.

Affiant does not understand English

Use a language the affiant understands or obtain a reliable translation. The notary must not proceed if there is reason to believe the affiant does not understand the transaction or is acting involuntarily. The recipient may require the translator’s affidavit or a certified translation.

Affidavit executed abroad

A person abroad may generally use:

A Philippine embassy or consulate offering notarial services; or
A local notary or competent authority followed by an Apostille, when the country and document fall under the Apostille Convention.

For a non-Apostille country, authentication or legalization requirements may apply. Foreign requirements vary, and some Philippine agencies prescribe special affidavit forms or additional supporting records. Check the relevant Philippine foreign service post and the intended recipient before execution. The Department of Foreign Affairs’ consular-post instructions commonly require personal appearance and a valid passport for consular notarization.

Affidavit for court or agency filing

Notarization alone does not establish that a filing is timely or procedurally sufficient. Court pleadings, complaint-affidavits, counter-affidavits, certifications against forum shopping, affidavits of service, administrative complaints, and bid or licensing documents may have separate requirements concerning:

Who must sign.
The required wording.
Personal knowledge.
Authority to sign for an organization.
The number and certification of copies.
Supporting exhibits.
Filing method.
Filing fee.
Service on other parties.
A specific deadline.

Follow the governing rule, order, subpoena, notice, or agency checklist. A court may sometimes permit correction of a defective verification, but this is fact-dependent and should never be treated as an automatic right. Certifications against forum shopping receive particularly strict treatment and may carry serious consequences if false or incomplete.

Does an affidavit expire?

There is no universal rule that every Philippine affidavit expires after a fixed number of months. Its usefulness depends on:

The date and continuing accuracy of the facts stated.
The governing law or agency rule.
The recipient’s written requirements.
Whether a transaction or status has changed.
Whether the affidavit must accompany a filing made within a particular deadline.

An agency may require a recently executed affidavit even when no general law sets an expiration period. Never alter the date or have an old affidavit re-notarized without reviewing and re-executing its contents. If circumstances have changed, prepare a new truthful affidavit.

Effect of defective notarization

A defect does not produce the same consequence in every case.

As a general evidentiary rule, defective notarization may strip a document of its character as a public document and reduce it to a private document. It may then lose the presumption of regular execution and authenticity ordinarily enjoyed by a properly notarized instrument.

That does not automatically mean every underlying agreement or statement becomes void. The result depends on whether notarization or execution in a public instrument is:

Required only for evidentiary convenience;
Required to affect third persons;
Required for registration; or
An indispensable legal requirement for validity.

For example, a donation of immovable property must satisfy the Civil Code’s public-document requirements. A defective notarization can therefore be fatal in circumstances where the law requires a public instrument for validity. The Supreme Court explains this distinction in Patenia-Kinatac-an v. Patenia-Decena, G.R. No. 238325.

False statements and perjury

An affidavit is made under oath. Knowingly making a material false statement in an affidavit required by law or made for a legal purpose may constitute perjury when the statutory elements are established.

Republic Act No. 11594 amended Article 183 of the Revised Penal Code and increased the penalty for perjury to prisión mayor in its minimum period, generally six years and one day to eight years. Additional consequences apply under the statute, including a fine of up to ₱1,000,000; special consequences apply when the offender is a public officer or employee.

A mistake, uncertainty, or disputed recollection is not automatically perjury. Criminal liability requires proof of the statutory elements, including a willful and deliberate material falsehood. Still, never guess, exaggerate, conceal a material qualification, or sign facts supplied by someone else without checking them. Read Republic Act No. 11594 for the current text.

Evidence to preserve

Keep:

A complete copy of the signed and notarized affidavit.
Copies of every exhibit exactly as attached.
The receipt for the notarial service.
The name, office address, and commission details of the notary.
A copy or clear photograph of the completed jurat and seal.
Proof of when and where the affidavit was submitted.
Courier receipts, electronic filing confirmations, and acknowledgment emails.
Source records supporting each statement, including original messages and metadata where relevant.
Any appointment confirmation or electronic-notarization audit record provided to you.

Do not write on, detach pages from, or substitute attachments in the notarized original. If a material correction is needed, execute a corrected or supplemental affidavit and disclose the earlier version when appropriate.

Common mistakes

Signing before meeting the notary.
Using an expired, private, altered, or unreadable ID.
Leaving names, dates, amounts, or exhibit references blank.
Using a jurat when an acknowledgment is legally required.
Copying a generic online form that does not match the recipient’s rules.
Stating conclusions, accusations, or hearsay as firsthand facts.
Failing to identify or attach referenced evidence.
Letting only one affiant appear for a joint affidavit.
Assuming notarization proves that every statement is true.
Assuming every notarized document is automatically valid.
Using an ordinary video call as remote notarization.
Backdating the document to meet a deadline.
Ignoring separate filing, service, Apostille, registration, or agency requirements.
Treating a defective court affidavit as harmless without obtaining legal advice.

Practical checklist

Before paying or leaving the notarial office, confirm that:

The affidavit is complete and all pages are present.
Your name matches your identification.
All factual statements remain accurate.
Every attachment is correctly labeled.
You personally signed before the notary.
The oath or affirmation was actually administered.
The date and venue are correct.
Your identity details are properly reflected.
The notary signed and affixed the seal.
The commission and register details are complete.
You received a full copy.
You know the recipient’s submission deadline and filing method.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The affidavit concerns a crime, arrest, subpoena, or pending investigation.
You are asked to execute a complaint-affidavit or counter-affidavit under a short deadline.
The document concerns land, inheritance, corporate authority, a large debt, or transfer of ownership.
Someone asks you to backdate, alter, or sign an incomplete document.
Your signature, identity, or notarized document was forged or used without authority.
A notary certified that you appeared when you did not.
An adverse party challenges the affidavit’s authenticity or notarization.
A court or agency has rejected the document.
The affidavit contains an admission that may expose you to civil, criminal, tax, immigration, or administrative liability.
The affiant is abroad, incapacitated, unable to understand the document, or unable to sign normally.

If a filing deadline is approaching, seek help immediately rather than waiting to perfect the document. Notarization does not extend a court or agency deadline.

Frequently asked questions

Can I sign the affidavit at home?

For an ordinary paper jurat, no. The affidavit must be signed in the notary’s presence. If you already signed it, the notary may require a clean reprint and a new signature.

Is one valid ID enough?

One current official-agency identification document bearing your photograph and signature may satisfy the general rule. The notary or receiving institution may reasonably require additional proof where identity is doubtful or a special rule applies.

Is a cedula enough?

Do not rely on a cedula alone. The current identity rule calls for qualifying official identification bearing a photograph and signature unless the affiant is personally known to the notary or is identified through compliant credible witnesses.

Can a relative appear or sign for me?

Ordinarily, no. An affidavit is the affiant’s personal sworn statement. A representative cannot take another person’s oath or attest to facts that only the absent person knows.

Can the notary prepare the affidavit?

A lawyer may draft an affidavit, but the factual statements must come from the affiant and must be reviewed carefully. The lawyer drafting or advising on a transaction should also consider conflicts, disqualifications, and the distinct responsibilities involved in acting as notary.

Does notarization prove that the affidavit is true?

No. Notarization authenticates the notarial act, identity, appearance, signature, and oath in accordance with the applicable rules. It does not independently prove the truth of every factual assertion.

Can an affidavit be notarized online?

Only through a compliant electronic-notarization process performed by a duly commissioned electronic notary public. An emailed scan, pasted electronic signature, or ordinary video call is not enough.

Must every affidavit be Apostilled?

No. An Apostille is generally relevant when a public document will be used in another Apostille Convention country. Domestic use ordinarily does not require it. Confirm the destination country’s and recipient’s requirements.

How much should notarization cost?

There is no single nationwide price for every private notarial act. Fees can vary with the document, location, drafting work, copies, and applicable office rules. Ask for the disclosed fee before proceeding and request a receipt. Government and consular services may follow separate official fee schedules.

Can a defective affidavit be corrected?

Sometimes, but the proper remedy depends on the defect and the proceeding. A fresh, corrected, or supplemental affidavit may be appropriate; a court may permit correction of some formal defects. Do not erase, substitute pages, alter the jurat, or arrange a new seal on the old signature.
