Quick answer

An affidavit is a written statement of facts that the affiant swears or affirms to be true before a person authorized to administer oaths—usually a commissioned notary public. For ordinary paper notarization, the affiant must personally appear before the notary, prove identity through competent evidence, sign the affidavit in the notary’s presence, and take an oath or affirmation.

A notary should not notarize a blank or incomplete affidavit, a document containing false information, or an affidavit signed by someone who did not personally appear. Sending a signed document and an ID through a messenger is not a valid substitute for personal appearance.

Not every document needs notarization. The governing law, court rule, agency instruction, contract, or receiving institution determines whether an affidavit or notarized instrument is required. Electronic notarization is legally recognized under Supreme Court rules, but it must be performed by a duly commissioned electronic notary through the authorized electronic-notarization framework—not through an informal video call alone.

What makes a document an affidavit?

An affidavit ordinarily contains:

The affiant’s full name and relevant personal details;
A clear statement that the affiant is executing the document under oath;
Numbered or logically arranged statements of facts;
Facts based on the affiant’s personal knowledge, with the source identified when information comes from records or another person;
References to supporting documents, if any;
The affiant’s signature; and
A proper jurat completed and signed by the notary or other authorized officer.

An affidavit should state only facts the affiant can truthfully affirm. Legal conclusions, accusations, estimates, and second-hand information should be identified carefully rather than presented as personally witnessed facts.

There is no single form applicable to every affidavit. An affidavit of loss, complaint-affidavit, affidavit of support, affidavit of discrepancy, judicial affidavit, and affidavit of adverse claim serve different purposes and may have different statutory or agency requirements.

Jurat versus acknowledgment

The distinction matters because an affidavit ordinarily requires a jurat, not merely an acknowledgment.

Jurat

In a jurat, the affiant:

Personally appears before the notary;
Is personally known to the notary or identified through competent evidence of identity;
Signs the affidavit in the notary’s presence; and
Takes an oath or affirmation that the statements in it are true.

The notarial certificate usually begins with language such as “Subscribed and sworn to before me.”

Acknowledgment

In an acknowledgment, the signatory personally appears and declares that the signature on the document is genuine and that the document is the signatory’s free and voluntary act and deed. This is commonly used for contracts, deeds, special powers of attorney, and similar instruments.

An acknowledgment does not automatically turn a factual statement into sworn testimony. If the document is intended to be an affidavit, its notarial certificate should ordinarily be a jurat.

Basic requirements for paper notarization

Personal appearance

The person whose signature is being notarized must personally appear before the commissioned notary at the time of notarization. This allows the notary to:

Verify the person’s identity;
Observe whether the person appears willing and aware of the transaction;
Confirm that the document is complete;
Witness the signing when the notarial act requires it; and
Administer the oath or affirmation for an affidavit.

A notary cannot properly notarize a document solely because a secretary, relative, agent, or liaison presents it together with a photocopy of the signatory’s ID. The notary’s employee also cannot perform the notarial act or sign for the notary.

Competent evidence of identity

Under the amended 2004 Rules on Notarial Practice, identity may generally be established through at least one current identification document issued by an official agency and bearing the individual’s photograph and signature.

Examples identified in the Rules include passports, driver’s licenses, PRC IDs, government-issued employment IDs, SSS cards, GSIS e-cards, senior-citizen cards, and other qualifying government-issued identification documents. Because ID formats and verification systems change, confirm in advance whether the particular ID satisfies the current Rules and the receiving institution’s requirements.

If the affiant has no qualifying identification document, the Rules provide an alternative involving credible witnesses under specified 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 the required documentary identification.

A credible witness must not be a party to or otherwise privy to the instrument, document, or transaction.

Bring the original ID, not merely a photograph or photocopy. The notary may record the ID’s type, number, issuance or expiry details, and other information required for the notarial register and certificate.

Complete document

Before notarization, the affidavit should contain:

The complete factual statements;
All pages and referenced attachments;
The affiant’s correct name and details;
The correct date and place of execution;
No unexplained blank spaces;
No unauthorized alterations; and
The appropriate notarial certificate.

The notary must refuse to place a signature or seal on an incomplete notarial certificate. Material corrections should be made before notarization and handled in a way that prevents later alteration.

Understanding and voluntary execution

The notary must be satisfied that the affiant understands the document and is signing voluntarily. Tell the notary if the affiant:

Cannot read the document;
Does not understand the language used;
Has a disability affecting communication or signing;
Requires an interpreter;
Is seriously ill or under medication;
Is signing by mark or thumbmark; or
Appears to have difficulty understanding the transaction.

Additional safeguards or witnesses may be needed. A notary should refuse the act if the affiant appears coerced, unaware of the document’s meaning, or incapable of executing it knowingly.

Can an affidavit be signed before going to the notary?

For a jurat, the Rules contemplate signing in the notary’s presence. The safer practice is therefore to leave the signature portion unsigned until the affiant personally appears before the notary.

Do not backdate the affidavit or ask the notary to certify that an appearance occurred on a date when it did not. The date and place in the jurat should reflect the actual notarial act.

Can notarization be completed online?

The Supreme Court’s Rules on Electronic Notarization recognize:

In-person electronic notarization; and
Remote electronic notarization conducted through an authorized electronic-notarization facility.

These are regulated processes. They require a properly commissioned electronic notary public, compliant electronic signatures and seals, identity verification, recordkeeping, and use of the authorized facility and procedures. A scanned signature, emailed ID, ordinary video conference, or pasted image of a notarial seal does not by itself satisfy the Rules.

For an electronic affidavit, first verify:

Whether the intended recipient accepts an electronically notarized document;
Whether an authorized electronic notary is available;
Whether the document type is eligible for electronic notarization;
What digital identity and signing requirements apply; and
Whether a paper original, certified electronic copy, or facility-generated verification record must be submitted.

The Supreme Court maintains an official eNotarization portal containing the governing rules, public guidance, and available information on electronic notaries and accredited facilities.

Does notarization prove that every statement is true?

No. Notarization establishes the performance of the notarial act, including personal appearance, identification, execution, and—when applicable—the administration of an oath. It does not independently investigate or guarantee the truth of every factual assertion.

A properly notarized document generally enjoys the evidentiary character of a public document as to its due execution. Its contents may still be challenged through competent evidence. Fraud, forgery, lack of authority, incapacity, mistake, simulation, coercion, and illegality are not cured merely by notarization.

The Supreme Court has repeatedly explained that notarization is not an empty or routine act. It converts a private document into a public document and gives it evidentiary consequences, which is why personal appearance and proper identification are indispensable. See Sanchez v. Inton, A.C. No. 12455, November 5, 2019.

Is an unnotarized affidavit valid?

An unsigned or unsworn statement is ordinarily not an affidavit because no oath or affirmation was administered.

A defectively notarized document may be treated as a private document rather than a public document. Whether the underlying agreement or declaration remains effective depends on the applicable law. Some transactions are valid between the parties even if not notarized, while others require a public instrument, registration, or another formal requirement for validity, enforceability, or effect against third persons.

Do not assume that notarization is optional merely because the parties agree. Deeds affecting land, powers of attorney for particular transactions, corporate filings, court submissions, and agency applications may be governed by special formalities.

Special requirements for judicial affidavits

A judicial affidavit used as direct testimony in covered court proceedings is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, it must generally include:

The witness’s name, age, address, and occupation;
The lawyer’s name and address and the place of examination;
A statement that the witness is answering under oath and understands the possible liability for false testimony or perjury;
Consecutively numbered questions and answers;
Facts showing how the witness acquired personal knowledge;
Identification and authentication of attached evidence;
The witness’s signature;
A jurat; and
The examining lawyer’s sworn attestation against coaching and inaccurate recording.

In covered proceedings, judicial affidavits and exhibits generally must be filed and served no later than five days before the pre-trial, preliminary conference, or scheduled hearing on a motion or incident. Criminal cases and particular proceedings have additional rules and exceptions. Late or noncompliant submissions can be excluded, subject to the Rule’s limited relief provisions.

A witness must ordinarily still appear for cross-examination. Filing the affidavit does not automatically excuse the witness from attending the hearing.

Affidavits for government agencies and private institutions

The receiving office may prescribe its own form, required wording, attachments, number of copies, documentary-stamp treatment, validity period, or filing channel. Examples include affidavits submitted to:

Courts and prosecutors’ offices;
The Registry of Deeds;
The Philippine Statistics Authority or local civil registrar;
The Bureau of Immigration;
The Securities and Exchange Commission;
The Department of Labor and Employment;
Banks, insurers, schools, and employers; and
Embassies, consulates, and foreign authorities.

Obtain the current official checklist before drafting. A technically notarized affidavit can still be rejected if it addresses the wrong issue, uses an obsolete form, lacks attachments, or fails to comply with the recipient’s specific rule.

Documents signed outside the Philippines

An affidavit intended for use in the Philippines may be executed abroad through an authorized Philippine embassy or consulate, subject to the post’s current requirements. Another possible route is notarization before a competent foreign notary followed by an apostille or authentication, depending on the country of execution, the intended use, and applicable treaty arrangements.

An apostille authenticates the origin of a public document for international use; it does not prove that the document’s factual contents are true. Consular procedures, appointment systems, fees, acceptable IDs, witness requirements, translations, and mailing rules vary by post. Consult the relevant Philippine foreign-service post and the DFA Apostille information page before execution.

Practical steps before signing

Ask why the affidavit is needed. Obtain the statute, official checklist, court order, or institutional form governing it.
Confirm the filing deadline. Notarization does not extend a court, prosecutor, agency, contractual, or registration deadline.
Draft from first-hand facts. Separate what the affiant personally saw, heard, did, or received from assumptions and second-hand information.
Check names and dates against records. Use the spelling shown in official documents and explain material discrepancies.
Identify attachments accurately. Label each attachment and refer to it in the affidavit.
Review every page. Remove unintended blanks and correct inconsistent dates, names, addresses, amounts, and document references.
Bring the complete unsigned document. Bring all attachments and the original qualifying identification document.
Appear personally. Do not send only the affidavit, signature page, or ID through another person.
Take the oath or affirmation. Confirm that the notary completes the jurat, signs it, affixes the seal, and supplies the required commission and register details.
Keep a complete copy. Retain the notarized affidavit, attachments, filing receipt, transmission record, and any acknowledgment issued by the recipient.

Evidence to preserve

Depending on the affidavit’s purpose, preserve:

Original contracts, receipts, invoices, and official records;
Emails, text messages, chat exports, and transaction confirmations;
Photographs, videos, and original electronic files with metadata;
Delivery records, demand letters, and proof of receipt;
Bank and e-wallet records obtained through lawful channels;
Police, barangay, medical, employment, or government records;
Copies of IDs used for the transaction, when lawfully obtained;
Names and contact details of witnesses;
The complete notarized affidavit and all attachments; and
Proof of filing and the date the receiving office accepted it.

Do not edit original electronic evidence or fabricate screenshots. Preserve the original device or account when authenticity may later be disputed.

Common mistakes

Treating an affidavit as a formality and signing without reading it;
Including facts supplied entirely by another person without identifying the source;
Signing a jurat before meeting the notary;
Allowing a representative to “have it notarized” without the affiant;
Using an expired or nonqualifying ID without arranging proper credible witnesses;
Leaving material blanks to be filled after notarization;
Attaching documents that are not identified or explained;
Using an acknowledgment when the document must be sworn;
Assuming that notarization proves the truth or legality of the contents;
Backdating the document or using a false place of execution;
Assuming an electronic signature or video call is automatically electronic notarization;
Ignoring a prescribed agency form or court deadline; and
Discarding the filed copy or proof of submission.

False statements and fraudulent notarization

A person who knowingly makes a material false statement under oath may incur liability for perjury under Article 183 of the Revised Penal Code, depending on the facts and the presence of all legal elements. False documents, forged signatures, fabricated evidence, and fraudulent use of notarized instruments may also create separate civil, criminal, procedural, or administrative consequences.

A commissioned lawyer-notary who disregards personal appearance, identity verification, notarial-register requirements, or other safeguards may face revocation of the notarial commission, disqualification from future commissions, and professional discipline. The particular sanction depends on the applicable rules and circumstances.

If a document appears to have been notarized without your appearance or consent, secure a certified copy if available, preserve signature specimens and location records, identify the notarial details, and obtain legal advice before confronting suspected participants or surrendering original evidence.

When legal help is urgent

Consult a lawyer promptly when:

A court, prosecutor, or agency deadline is approaching;
The affidavit concerns arrest, detention, violence, threats, child safety, or possible criminal liability;
You are being asked to admit a debt, offense, breach, or waiver of rights;
The document involves land, inheritance, corporate ownership, immigration status, or a substantial financial transaction;
Someone wants you to sign a blank, backdated, or inaccurate affidavit;
The affiant has difficulty understanding the document or appears under pressure;
A signature or notarial certificate may have been forged;
The affidavit will be used abroad or was executed abroad;
A government office has rejected the document; or
The affidavit is intended as testimony in an active case.

A notary’s role in administering the notarial act is different from a lawyer’s role in advising whether the affidavit protects your interests. Notarization alone does not mean the document has received a legal review.

Frequently asked questions

How many valid IDs are required?

The Notarial Rules generally recognize at least one current official identification document bearing the individual’s photograph and signature. The notary or receiving institution may require additional documents where identity, name discrepancies, authority, or a special transaction must be verified.

Is a barangay certificate acceptable identification?

The amended Rules include barangay certification among the examples of official identification documents, but the actual document must satisfy the governing identity requirements. Confirm acceptability with the notary and receiving office before relying on it.

Can a relative bring my affidavit to a notary?

The relative may assist with logistics, but cannot replace the affiant’s required personal appearance. A paper affidavit should not be notarized merely upon delivery by another person.

Can the notary prepare the affidavit?

A lawyer may draft an affidavit when engaged to provide legal services. Preparation and notarization are distinct functions, and professional fees for drafting may be separate from the notarial fee. The affiant remains responsible for reviewing and truthfully confirming the facts.

Does an affidavit expire?

There is no universal expiration period for every affidavit. A law, agency, embassy, bank, employer, or transaction may require a recently executed affidavit or impose a specific validity period. Even without a formal expiration date, an affidavit may become inaccurate when circumstances change.

Can I use a photocopy of a notarized affidavit?

That depends on the recipient. Some offices accept a copy, while others require the original, a certified copy, or an electronically verifiable document. Never detach or substitute pages or attachments.

May corrections be made after notarization?

Material changes should not be inserted after notarization. Execute a corrected affidavit or follow the receiving office’s prescribed correction procedure. Altering a notarized document can undermine its authenticity and may have serious consequences.

Is a notary required to notarize every document presented?

No. A notary must refuse when legal requirements are not met—for example, when the signatory is absent, identity cannot be established, the document or certificate is incomplete, the transaction appears unlawful, or the signatory appears unwilling or incapable of understanding the act.
