Quick answer

An affidavit is a written statement of facts that the affiant swears or affirms to be true. For an ordinary paper affidavit in the Philippines, the affiant generally must:

state facts within the affiant’s personal knowledge;
review the completed document and correct any errors;
personally appear before a duly commissioned notary public or another officer authorized to administer oaths;
present acceptable proof of identity 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 a jurat, signs it, affixes the official seal, and records the act in the notarial register. Merely signing an affidavit at home and later sending it to a notary is not proper notarization. A video call, scanned ID, courier delivery, or another person’s appearance ordinarily cannot replace personal appearance for paper notarization.

Notarization authenticates the execution of the document and the administration of the oath. It does not establish that every factual statement in the affidavit is true, cure falsehoods or legal defects, or guarantee that the receiving court, agency, bank, school, embassy, or private institution will accept it.

What an affidavit should contain

There is no single form for every affidavit. The contents depend on its purpose, but a properly prepared affidavit commonly includes:

a caption or descriptive title;
the affiant’s full name and relevant personal circumstances;
a clear statement that the affiant is competent to testify and is making the affidavit voluntarily;
separately numbered factual statements;
the source of the affiant’s knowledge;
identification of attached documents, photographs, messages, or other exhibits;
a statement of the affidavit’s purpose;
the affiant’s signature; and
a properly completed jurat.

Use the name appearing on the affiant’s identification document. If the person uses another name, has married, or has inconsistent records, explain the discrepancy and bring supporting documents.

An affidavit should generally contain facts, not arguments or conclusions. Dates, places, persons, conversations, payments, and events should be stated as precisely as the affiant can truthfully recall. If a fact was learned from someone else or from a document, say so instead of presenting it as firsthand knowledge.

Never sign an affidavit containing blank spaces, unfinished paragraphs, unattached exhibits, or facts the affiant has not verified.

Jurat and acknowledgment are different

The correct notarial act depends on the document.

Jurat

A jurat is normally used for an affidavit, complaint-affidavit, counter-affidavit, verification, or other sworn statement. Under the 2004 Rules on Notarial Practice, the affiant must:

personally appear before the notary;
sign the document in the notary’s presence; and
take an oath or affirmation regarding the truth of its contents.

The jurat commonly begins with “Subscribed and sworn to before me,” but the wording alone is not enough. The required appearance, signing, identification, and oath must actually occur.

Acknowledgment

An acknowledgment is commonly used for contracts, deeds, powers of attorney, and other instruments. The signatory personally appears and represents to the notary that:

the signatory executed the document;
the signature was voluntarily affixed; and
the document is the signatory’s free act and deed—or, for an authorized representative, the free act and deed of the represented person or entity.

An acknowledgment does not ordinarily require the signer to swear that every statement in the document is true. Replacing a required jurat with an acknowledgment may therefore be a material defect.

Personal appearance is the general rule

For conventional notarization of a paper affidavit, the affiant must be physically present before the notary at the time of notarization. The notary must be able to verify the affiant’s identity, observe the signing, administer the oath, and assess whether the act appears voluntary.

The Supreme Court has repeatedly treated personal appearance as an indispensable safeguard. In Tabao v. Lacaba, it rejected the claim that a video call and signatures made by representatives could substitute for the affiants’ personal appearance. A person ordinarily cannot authorize somebody else to swear to facts that only the affiant personally knows.

Accordingly, be cautious if anyone proposes to:

notarize a document while the affiant is abroad or in another city;
accept only a photograph or scanned copy of an ID;
allow a relative, employee, liaison, or messenger to appear for the affiant;
backdate the notarization;
notarize a signature already affixed outside the notary’s presence when a jurat is required; or
complete the certificate without administering an oath.

These shortcuts can undermine the affidavit’s reliability and expose the notary and participating persons to legal consequences.

What identification is acceptable?

“Competent evidence of identity” generally means at least one current identification document issued by an official agency bearing the holder’s photograph and signature. The Supreme Court’s 2008 amendment lists examples such as:

passport;
driver’s license;
PRC ID;
NBI or police clearance bearing the required features;
voter’s ID;
GSIS e-card;
SSS card;
PhilHealth card;
senior-citizen card;
OWWA or OFW ID;
seaman’s book;
alien certificate of registration;
government-office ID; and
qualifying government certifications.

The list is illustrative, but the document must satisfy the rule’s requirements. The current-ID standard is found in the Supreme Court’s amendment to Rule II, Section 12.

The notary may also identify a person through the oath or affirmation of a credible witness personally known to the notary and who personally knows the affiant, or through two credible witnesses who meet the conditions prescribed by the rules. This is not simply permission to bring any two companions. The notary must determine that all legal requirements are satisfied.

A notary may ask for additional identification where there are inconsistencies or reasonable doubts. Bringing two current government-issued IDs is prudent, even though the rule does not universally require two IDs.

Signing for a person who is physically unable to sign

Physical inability to write is different from absence.

The notarial rules permit a notary, in a narrowly defined situation, to sign on behalf of a person who is physically unable to sign or make a mark. Among the safeguards are:

the person must personally direct the notary to sign;
the signing must occur in the presence of two disinterested and unaffected witnesses;
both witnesses must sign;
the required notation must be written below the notary’s signature; and
the notary’s signature must itself be notarized through an acknowledgment or jurat.

This procedure is not available merely because the person is overseas, busy, hospitalized elsewhere, or unable to travel. Capacity, voluntariness, the person’s actual physical condition, and the exact formalities must be assessed before using it.

When a notary must refuse

A notary should refuse to perform the act when the legal requirements are not satisfied. Grounds include circumstances where:

the affiant is not personally present;
identity has not been satisfactorily established;
the document is blank or incomplete;
the affiant does not understand the document or appears unable to act knowingly;
the signature or oath is not voluntary;
the transaction appears unlawful;
the notary knows or has good reason to believe that the act is false or fraudulent;
the notary is a party to the document or will receive a direct benefit from it; or
the notary is disqualified because of the relationship specified in the rules.

A notary’s commission is territorial. For conventional paper notarization, the notarial act must be performed within the regular place of work or business stated in the commission, subject to the limited locations allowed by the rules. A lawyer is not automatically authorized to notarize everywhere merely because the lawyer is a member of the Philippine Bar.

What should appear in the notarization?

A properly completed paper affidavit should normally show:

the venue, identifying the province and city or municipality where the notarial act occurred;
the date of the oath;
the affiant’s name;
the identification presented and relevant details;
the notary’s signature and official seal;
the notary’s commission details; and
the document, page, book, and series information corresponding to the notarial register.

The notary must also make the required register entry and retain or submit copies in accordance with the amended rules. Since June 21, 2025, notaries have been subject to additional digital recordkeeping and monthly reporting requirements under the Supreme Court’s amendments to the 2004 Notarial Rules. These reporting duties fall principally on the notary, but a document holder should still keep a complete copy showing the notarial details.

A missing seal, incomplete jurat, impossible venue, incorrect date, absent register details, or expired commission is a warning sign requiring verification.

Electronic notarization: current position

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, created a separate framework for electronic documents. The rules contemplate in-person, remote, and hybrid electronic notarization through authorized electronic notaries and accredited facilities, with prescribed identity-verification, electronic-signature, recording, and security safeguards.

However, electronic notarization is not the same as emailing a scanned affidavit to an ordinary notary or appearing through an informal video call. It must be conducted under the Supreme Court’s official system and by a duly commissioned Electronic Notary Public.

As of the source check for this article, the Supreme Court has opened applications for Electronic Notaries Public, but announced that the eNotarization service will become operational on October 19, 2026. Until a compliant service is operational and available for the particular document, parties should follow the conventional paper-notarization requirements. Current implementation notices, rules, and public guidance are available on the Supreme Court’s eNotarization portal.

Notarial wills, depositions, and paper documents bearing handwritten signatures remain subject to their applicable conventional rules and are not converted into electronic documents merely by scanning them.

Special affidavits may have additional requirements

Notarization is only one part of compliance. The court, agency, or transaction may impose its own form, contents, attachments, witnesses, filing method, and deadline.

Affidavits in preliminary investigation

Under Rule 112 of the Rules of Criminal Procedure, complaint-affidavits and supporting affidavits in preliminary investigations are generally subscribed and sworn to before a prosecutor or another government officer authorized to administer oaths. A notary public may administer the oath when no such officer is available. The officer must certify that the affiant was personally examined and voluntarily executed and understood the affidavit.

A generic jurat may not satisfy every prosecutorial requirement. Follow the instructions of the receiving prosecution office and use the prescribed form, if any.

Judicial affidavits

A judicial affidavit is governed by the Judicial Affidavit Rule, A.M. No. 12-8-8-SC. It is not merely an ordinary narrative affidavit. It must generally use a question-and-answer format and contain the witness’s personal circumstances, manner of examination, oath, identification of exhibits, and the examining lawyer’s sworn attestation.

The rule also has filing and service requirements tied to the hearing or pretrial. An ordinary notarized affidavit should not be substituted for a judicial affidavit without checking the applicable procedural rule and court order.

Affidavits for government agencies or private institutions

Agencies, banks, insurers, schools, employers, registries, embassies, and licensing bodies may require:

a prescribed template;
specified supporting documents;
witnesses;
recent execution;
particular wording;
consular authentication or an apostille;
translation; or
notarization by a designated officer.

Obtain the receiving institution’s latest written checklist before execution. A properly notarized affidavit can still be rejected if it does not meet the institution’s substantive requirements.

Affidavits for use abroad

The foreign recipient may require further authentication after notarization. Depending on the destination country and type of document, this may involve an apostille from the Department of Foreign Affairs or another process. Consult the DFA’s current Apostille guidance and the requirements of the foreign recipient before notarizing the document.

Does notarization make the affidavit conclusive?

No. Notarization gives a document evidentiary advantages as a public document, but it does not make its contents indisputably true.

The opposing party may still challenge:

the truth or accuracy of the statements;
the affiant’s personal knowledge;
voluntariness;
authenticity of the signature;
the notary’s authority or commission;
compliance with personal-appearance and identification rules;
alterations made after notarization; or
fraud, forgery, mistake, or lack of capacity.

A defective notarization may cause a purportedly public document to be treated as a private document requiring proof of authenticity. Whether the underlying transaction also becomes invalid depends on the law governing that transaction. Under Articles 1356 to 1358 of the Civil Code, form may be required for validity, enforceability, proof, registration, or the convenience of the parties. The consequences therefore cannot be determined from the notarial defect alone.

False statements and perjury

An affidavit is made under oath. A person should not sign one merely because a lawyer, employer, relative, investigator, or government employee prepared it.

Article 183 of the Revised Penal Code, as amended, penalizes perjury when a person knowingly makes an untruthful statement under oath on a material matter before a competent person, in a situation where the law requires or permits the oath. The prosecution must prove all required elements; an honest mistake, uncertain recollection, or immaterial inaccuracy is not automatically perjury.

Possible civil, administrative, professional, employment, or case-related consequences may also arise. Correct a material error before signing. If an error is discovered after submission, obtain advice promptly about a supplemental, corrected, or withdrawal affidavit rather than altering the notarized document.

Practical steps before notarization

Ask for the receiving party’s requirements. Confirm the correct form, attachments, number of copies, acceptable language, filing method, and deadline.
Prepare a complete draft. State only facts that can be truthfully supported. Identify hearsay, estimates, and matters based on records.
Check names and details. Compare names, addresses, dates, ID numbers, property descriptions, case numbers, and exhibit labels against the source documents.
Attach the exhibits before signing. Mark them consistently and confirm that every referenced attachment is present.
Bring valid identification. Use a current government-issued document bearing a photograph and signature. Bring supporting civil-registry documents if names differ.
Appear personally. Do not send only the signed affidavit, an ID photograph, or a representative.
Sign only when instructed. For a jurat, the signature should be made in the notary’s presence.
Take the oath seriously. Tell the notary if the affidavit is not understood, contains an error, or was prepared in an unfamiliar language.
Inspect the completed jurat. Check the date, venue, name, ID details, notary’s seal and signature, commission information, and register particulars.
Keep a complete copy. Preserve the affidavit exactly as notarized, including every page and exhibit.

Evidence to preserve

If the affidavit may later be disputed, preserve:

the final notarized original and complete copies;
earlier drafts showing legitimate corrections;
the government ID presented;
receipts or official records relating to the notarial act;
emails or messages transmitting the draft and attachments;
the documents, photographs, recordings, or records supporting each material statement;
proof of when and how the affidavit was filed or delivered;
the receiving office’s acknowledgment or reference number; and
evidence of the notary’s office location and commission details, if authenticity becomes an issue.

Do not write on, remove pages from, replace exhibits in, or alter a notarized affidavit. Any necessary correction should be handled through a properly executed new or supplemental document.

Common mistakes

Signing before meeting the notary when a jurat is required.
Treating a video call with an ordinary notary as valid paper notarization.
Using an acknowledgment for a sworn affidavit.
Leaving blank spaces to be completed later.
Copying statements from another person without confirming them.
Signing an affidavit written in a language the affiant does not understand.
Using an expired or inadequate ID.
Failing to explain inconsistent names or civil-status records.
Attaching exhibits only after notarization.
Assuming notarization proves ownership, authority, or the truth of the statements.
Relying on an affidavit when the law requires another instrument, such as a deed, special power of attorney, verified pleading, or judicial affidavit.
Missing the underlying filing deadline while trying to perfect the notarization.
Paying a fixer who promises notarization without personal appearance.

When legal help is urgent

Seek prompt legal advice when:

a filing deadline, hearing, inquest, preliminary investigation, election period, tax deadline, or prescriptive period is approaching;
the affidavit could expose the affiant to criminal, civil, administrative, tax, immigration, or employment liability;
the document involves a waiver, desistance, admission, settlement, transfer of property, inheritance, corporate authority, or substantial money;
someone is pressuring the affiant to sign facts that are untrue or not personally known;
a signature, seal, date, venue, or notarial entry appears forged or irregular;
a notarized document was created without the purported affiant’s appearance or consent;
the affiant is elderly, ill, detained, hospitalized, unable to sign, or may lack capacity;
the affidavit will be used abroad; or
a submitted affidavit contains a material error.

If forgery or unauthorized notarization is suspected, preserve the questioned document and obtain a certified copy from the office where it was filed. Depending on the facts, remedies may involve the court or agency handling the matter, law-enforcement or prosecutorial authorities, the executive judge who commissioned the notary, or lawyer-disciplinary proceedings. Do not accuse a person publicly before the evidence has been assessed.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is, by nature, a sworn statement, so an oath or affirmation before an authorized officer is ordinarily required. The applicable law, rule, agency, or proceeding determines who may administer the oath and whether a notary public is appropriate.

Can I sign the affidavit before going to the notary?

For a jurat, the affiant is required to sign in the notary’s presence. Bring the completed but unsigned affidavit unless the receiving authority’s lawful procedure provides otherwise.

Are two valid IDs always required?

The notarial rules generally refer to at least one current official identification document bearing the person’s photograph and signature. A notary may reasonably request additional proof when identity or record consistency is uncertain.

Can a family member bring my affidavit and ID to the notary?

Not for a conventional jurat. The affiant must personally appear, sign in the notary’s presence, and take the oath. Delivery by a representative does not satisfy those requirements.

Can an affidavit be notarized through Zoom or another video-call application?

An informal video call with an ordinary notary does not comply with the conventional rules for paper notarization. Remote electronic notarization must use the authorized system, a commissioned Electronic Notary Public, and the safeguards required by the Rules on Electronic Notarization. The official service is scheduled to become operational on October 19, 2026.

Does an affidavit expire?

There is no universal expiration period for all affidavits. However, the receiving institution may require a recently executed affidavit, and changed circumstances can make an older statement inaccurate. Confirm the recipient’s rules.

Can I correct a notarized affidavit by handwriting over an error?

Do not alter it unilaterally. Material corrections should ordinarily be made through a newly executed, corrected, or supplemental affidavit, with proper notarization and disclosure of the earlier error where appropriate.

Is a notarized affidavit automatically accepted in court?

No. It must still be relevant, admissible, timely filed, and compliant with the applicable procedural rules. An ordinary affidavit may also be insufficient where testimony, cross-examination, a judicial affidavit, or a prescribed complaint-affidavit is required.

Does notarization make an invalid agreement valid?

Not necessarily. Notarization cannot supply missing consent, authority, capacity, lawful cause, required witnesses, or other substantive elements. Its effect depends on the governing law and the particular transaction.
