Quick answer

An affidavit is a written statement of facts that the affiant swears or affirms to be true before a duly commissioned notary public or another officer authorized to administer oaths. For an ordinary paper affidavit in the Philippines, the affiant generally must:

Review and complete the affidavit without material blanks.
Personally appear before the notary public.
Present competent proof of identity unless personally known to the notary under the governing rules.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its contents are true.
Allow the notary to record the act and complete the jurat.

A notary cannot lawfully notarize a paper affidavit merely because someone delivers a signed document and a photocopy of the affiant’s ID. Personal appearance and the administration of an oath or affirmation are essential.

Notarization does not prove that every statement in an affidavit is true. It establishes that the proper person appeared, was identified, signed, and swore or affirmed to the document under the required procedure.

What an affidavit should contain

The necessary contents depend on the affidavit’s purpose, but a properly prepared affidavit commonly includes:

The affiant’s complete name, age or confirmation of legal age, citizenship, civil status when relevant, and address;
A statement that the affiant is competent to testify about the matters stated;
Facts arranged clearly, preferably in numbered paragraphs;
Dates, places, names, amounts, document descriptions, and other material details;
A statement that the affidavit is being executed for a specified lawful purpose;
References to attachments, if any, using consistent exhibit labels;
The affiant’s signature; and
A jurat to be completed by the notary.

Only facts that the affiant personally knows should ordinarily be stated as facts. Information learned from another person should be identified accordingly, particularly when the affidavit will be submitted to a court, prosecutor, government agency, bank, employer, or registry.

Do not sign an affidavit containing statements you know are false. Depending on its use and the circumstances, a knowingly false sworn statement may expose the affiant to criminal, civil, administrative, employment, or procedural consequences.

Jurat versus acknowledgment

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

Jurat

In a jurat, the affiant:

Personally appears before the notary;
Presents an integrally complete affidavit;
Signs it in the notary’s presence; and
Takes an oath or affirmation that the statements are true.

The notary’s jurat commonly states that the affidavit was “subscribed and sworn to” before the notary.

Acknowledgment

In an acknowledgment, the person personally appears and declares that the signature was voluntarily affixed and that the instrument is the person’s free and voluntary act. If signing for a corporation, partnership, principal, or another person, the signer must also represent that the signer has authority to act in that capacity.

Acknowledgments are commonly used for deeds, contracts, powers of attorney, and similar instruments. They do not necessarily involve swearing that every factual statement in the document is true.

Changing the title of an acknowledgment to “jurat,” or vice versa, does not cure an incorrectly performed notarial act. The notary must perform the act actually required by the document and its intended use.

Personal appearance is mandatory for paper affidavits

Under the 2004 Rules on Notarial Practice, as amended, an affiant executing an ordinary paper affidavit must personally appear before the notary.

The following practices are improper:

Sending only the signed affidavit through a relative, employee, liaison, broker, or messenger;
Leaving a document and ID at a notarial office for later notarization;
Having another person sign for the affiant without a lawful and properly documented basis;
Asking the notary to use a signature previously placed on the affidavit;
Backdating the jurat;
Notarizing through an ordinary video call outside the applicable electronic-notarization framework; or
Notarizing a document when the notary cannot adequately identify the affiant.

The date stated in the jurat should be the date on which the affiant actually appeared, signed, and took the oath or affirmation.

Identification requirements

A person who is not personally known to the notary must be identified through competent evidence of identity.

Under the amended rule, this ordinarily means at least one current identification document issued by an official agency that bears the person’s photograph and signature. Examples recognized in the rule include a passport, driver’s license, PRC ID, government office ID, GSIS e-card, SSS card, senior citizen ID, seaman’s book, and alien registration documentation. The controlling definition appears in the Supreme Court’s 2008 amendment to the identification rule.

Because particular IDs can expire, change format, or lack a visible signature, it is prudent to bring:

The original current government-issued ID, not merely a photocopy or phone image;
A second current government-issued ID, if available; and
Any supporting document explaining a name discrepancy, such as a marriage certificate or annotated civil-registry record.

A community tax certificate or cedula by itself is generally not competent evidence of identity because it does not bear the holder’s photograph and signature. The Supreme Court reaffirmed this point in Ascaño v. Panem.

If the affiant lacks an acceptable ID, the rules provide a credible-witness method subject to strict conditions. Depending on whether the witness is personally known to the notary, one or two disinterested credible witnesses may be required. A witness who is a party to, benefits from, or is otherwise privy to the document or transaction may not satisfy the rule. Confirm the arrangement with the notary before attending.

The affidavit must be complete

A notary should not notarize a blank or materially incomplete document. Before appearing, check that:

All pages are present and arranged correctly;
Names, addresses, dates, amounts, property descriptions, and case numbers are complete;
Unused material spaces are appropriately closed or marked;
Corrections are clear and properly initialed where necessary;
Attachments referred to in the affidavit are present;
Page numbering is consistent; and
The jurat is not detached from, or placed on a page that could easily be substituted into, another document.

Do not permit anyone to add material statements after notarization. If a material correction becomes necessary, the safer course is usually to prepare and properly notarize a corrected or supplemental affidavit rather than alter the completed notarial document.

What the notary must verify

A notary is not merely a witness who applies a seal. The notary must determine that the required person is present, properly identified, and acting knowingly and voluntarily.

A notary must refuse the act when, among other grounds:

The affiant is absent;
The affidavit is blank or materially incomplete;
The affiant cannot be properly identified;
The affiant appears incapable of understanding the act;
The notary knows or has good reason to believe that the transaction is unlawful;
The affiant is being compelled or does not appear to act freely;
The notary has a prohibited financial or beneficial interest; or
The notarial act is outside the notary’s territorial authority or commission.

A notary’s commission is territorial. For traditional paper notarization, use a notary commissioned for the place where the notarial act is actually performed. The notary’s office address, commission details, roll number, PTR and IBP details, and commission expiration ordinarily appear in the notarial certificate or seal information.

Signing for a corporation or another person

An affidavit made in a representative capacity should clearly identify:

The affiant’s position or relationship to the principal;
The person or entity represented;
The source and scope of the affiant’s authority; and
Whether the facts are personally known, taken from official records, or both.

Bring the supporting authority requested for the transaction, such as a board resolution, secretary’s certificate, special power of attorney, government appointment, or corporate identification.

A representative cannot simply swear to another person’s personal knowledge. The affidavit must truthfully explain how the representative knows the stated facts and why the representative is authorized to execute it.

Affidavits of persons who cannot conventionally sign

A disability, illiteracy, or inability to sign does not automatically prevent a person from executing a sworn document. The notary must use the procedure permitted by the rules for a signature by mark or for a signature made on the person’s behalf. This may require disinterested witnesses, the affiant’s mark, and a specific notation in the notarial certificate.

Do not improvise by asking a relative to sign the affiant’s name. Inform the notary beforehand so the correct witnesses, identification, language assistance, and certificate can be arranged.

If the affiant does not understand the language used in the affidavit, it should be accurately translated or explained before signing. The affiant must understand the statements being sworn to.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, effective March 24, 2025, recognize:

In-Person Electronic Notarization, where an electronic document is notarized through an accredited electronic notarization facility while the principal physically appears; and
Remote Electronic Notarization, where the principal appears virtually through an accredited facility.

This is not the same as emailing a scanned affidavit to an ordinary notary or appearing through a casual Zoom, Messenger, or similar video call. The process must involve a duly commissioned electronic notary public and an accredited Electronic Notarization Facility, with the required identity verification, electronic signatures, records, and security controls.

Traditional paper documents bearing handwritten signatures remain governed by the 2004 Rules on Notarial Practice, as amended. The earlier pandemic-era Interim Rules on Remote Notarization of Paper Documents have been repealed by the current electronic-notarization rules.

The legal framework may already be in force even where accredited facilities or commissioned electronic notaries are not yet readily available in a particular location. Verify actual availability through the Supreme Court’s electronic-notarization portal before relying on a remote service.

Does every affidavit need notarization?

An affidavit is, by nature, a sworn or affirmed written statement. If a document has not been sworn to before an authorized officer, calling it an “affidavit” does not necessarily make it one.

However, whether a particular application, complaint, pleading, declaration, or supporting statement must be notarized depends on the statute, court rule, agency form, contract, or receiving institution governing it. Some procedures permit an unsworn declaration, certification, or verification in a prescribed form; others expressly require a notarized affidavit.

Always check the current requirements of the receiving court, prosecutor, agency, registry, school, employer, bank, or foreign authority. Notarization alone does not cure the use of the wrong form.

What notarization does—and does not do

Proper notarization ordinarily converts a private document into a public document for evidentiary purposes and gives the completed notarial certificate a presumption of regularity.

It does not:

Establish that every factual allegation is true;
Transfer ownership when substantive requirements for transfer are absent;
Cure forgery, fraud, lack of consent, illegality, or incapacity;
Supply missing corporate or representative authority;
Replace registration, recording, tax payment, or agency approval;
Make an inadmissible statement automatically admissible for every purpose; or
Guarantee that a court, agency, bank, or foreign authority will accept the document.

The Supreme Court repeatedly emphasizes that notarization is a public function, not an empty formality. A defective notarization may cause the document to be treated merely as a private document and may expose the notary to administrative sanctions.

Practical checklist before going to the notary

Bring the following:

The complete, unsigned affidavit, unless the receiving authority expressly requires a different procedure;
All original pages and attachments;
At least one current official ID bearing your photograph and signature, preferably two;
Supporting authority if signing in a representative capacity;
Documents explaining discrepancies in names or civil status;
Qualified credible witnesses, if the notary has confirmed that the witness-identification procedure is necessary;
Any witnesses required for a signature by mark or assisted signing; and
Enough copies for the receiving institution and your own records.

At the appointment:

Read every page.
Correct errors before signing.
Appear personally and present the original identification.
Sign only when instructed by the notary.
Take the oath or affirmation.
Check the date, place, document number, page number, book number, series, notary’s signature, and seal.
Obtain and preserve a complete copy.

Under the amended traditional notarial rules, notaries also have digitization, reporting, and transmission duties. Ask how the notary will provide the signatory’s digital copy and promptly report any discrepancy between it and the document actually signed.

Evidence to preserve

Keep:

The complete notarized affidavit and all attachments;
The digital copy transmitted by the notary, if applicable;
Proof of submission to the receiving institution;
Acknowledgment receipts, docket numbers, tracking records, and emails;
The source records supporting the sworn statements;
Drafts or instructions showing how material statements were verified;
Details of the notary’s commission and office; and
Messages or CCTV information showing personal appearance if the notarization is later disputed.

For a disputed affidavit, request certified records from the proper Clerk of Court as soon as possible. Notarial registers and submitted copies can be important in determining whether the purported affiant actually appeared and whether the document was reported.

Common mistakes

Avoid:

Signing before meeting the notary;
Using an expired ID or a cedula alone;
Sending a representative with your ID;
Leaving material blanks in the affidavit;
Swearing to legal conclusions or facts outside your knowledge;
Attaching altered, incomplete, or mislabeled exhibits;
Allowing a materially different page to be substituted after notarization;
Accepting a backdated or pre-signed jurat;
Assuming notarization proves ownership or validates the underlying transaction;
Using an unaccredited “online notary” for an electronic affidavit;
Ignoring different requirements imposed by the receiving authority; or
Losing the complete notarized and digitally transmitted copies.

When legal help is urgent

Consult a lawyer promptly if:

Your signature was forged or an affidavit was notarized without your appearance;
You were pressured, deceived, or made to sign a document you did not understand;
A false affidavit has been filed in court, with a prosecutor, or before a government agency;
The affidavit concerns land, inheritance, corporate control, substantial money, immigration status, custody, or criminal liability;
A deadline to file a counter-affidavit, complaint, protest, appeal, or verified pleading is running;
The notarial certificate, commission details, pages, or attachments appear altered;
An affidavit attributed to you is missing from the notarial records; or
A foreign authority requires authentication, consularization, or an Apostille.

Possible remedies depend on the facts and may include challenging the document’s authenticity or evidentiary value, seeking civil relief, reporting suspected criminal conduct, or filing an administrative complaint against the notary. Do not assume that defective notarization automatically cancels the underlying transaction; the proper remedy depends on the document, the parties’ genuine acts, and the relief sought.

Frequently asked questions

Can I sign the affidavit at home and have it notarized later?

Ordinarily, no. A paper affidavit requiring a jurat must be signed in the notary’s presence after personal appearance and identification.

Is one government ID enough?

One current official identification document bearing both photograph and signature can satisfy the general rule. Bring a second ID because the notary or receiving institution may need to resolve expiration, signature, name, or authenticity issues.

Is a barangay certification always accepted as ID?

Not automatically. It must satisfy the governing definition and allow reliable identification. Acceptance depends on its contents and form. Bring stronger photographic government identification whenever available.

Can a notary notarize an affidavit outside the notary’s commissioned area?

A traditional notary must act within the territorial jurisdiction covered by the commission. The location stated in the jurat must reflect where the act actually occurred.

Can my lawyer notarize my affidavit?

Possibly, if the lawyer holds a valid notarial commission and no rule, conflict, beneficial interest, evidentiary concern, or other disqualification applies. In litigation, counsel should also consider whether acting as notary could make counsel a necessary witness.

Is an affidavit valid forever?

Notarization does not ordinarily create a universal expiration date. The facts may become outdated, and the receiving institution may require a recently executed affidavit. Particular affidavits may also be subject to statutory or administrative time limits.

Does a notarized affidavit need an Apostille?

Only when it will be used abroad and the receiving foreign authority requires authentication. The notarization and Apostille serve different functions. Confirm the destination country’s requirements through the Department of Foreign Affairs Apostille guidance.

Can notarization be done entirely through an ordinary video call?

Not for an ordinary paper affidavit under the traditional rules. Remote electronic notarization must comply with A.M. No. 24-10-14-SC and use an accredited facility and properly commissioned electronic notary.

What if the notary never asked me to swear or affirm?

That may indicate a defective jurat. Preserve the document and surrounding evidence and obtain legal advice if the affidavit has already been submitted or affects important rights.

Does a notarized false statement become true or conclusive?

No. Notarization authenticates the performance of the notarial act; it does not make false statements true or prevent them from being challenged.
