Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. In the Philippines, it is ordinarily completed through a jurat: the affiant personally appears before an authorized officer, proves identity, signs the affidavit in that officer’s presence, and swears or affirms that its contents are true.

Do not sign an affidavit in advance unless the receiving office’s specific procedure expressly permits it. Bring the complete, unaltered document and a current government-issued identification document bearing your photograph and signature. The notary must record the act and ordinarily require you to sign or mark the notarial register.

Not every document needs notarization, and notarization does not make an inaccurate statement true or guarantee that an agency, prosecutor, or court will accept the document. The required form, officer, attachments, number of copies, and filing deadline depend on the transaction or proceeding.

What makes a document an affidavit?

A proper affidavit generally contains:

A title identifying its purpose, such as “Affidavit of Loss” or “Complaint-Affidavit.”
The affiant’s full name, age or legal capacity where relevant, citizenship when material, civil status when required, and address.
Numbered statements setting out facts clearly and chronologically.
Only facts the affiant personally knows, with the source identified when information comes from records or another person.
A statement explaining why the affidavit is being executed.
The affiant’s signature.
A completed jurat signed and sealed by the notary public or other officer authorized to administer the oath.
Any attachments referred to in the affidavit, properly identified and, when required, marked.

A notarial certificate is not decorative wording. It records what the notary actually did. Blank certificates, incomplete dates, missing locations, or certificates completed without the affiant’s appearance are serious defects.

Jurat versus acknowledgment

These notarial acts serve different purposes.

Notarial act	What the signer does	Typical use
Jurat	Appears before the notary, signs in the notary’s presence, and swears or affirms that the document is true	Affidavits, sworn statements, verifications
Acknowledgment	Appears before the notary and declares that an already executed instrument is the person’s free and voluntary act or deed	Deeds, contracts, powers of attorney and similar instruments

An affidavit normally requires a jurat, not merely an acknowledgment. Replacing one with the other can matter because an acknowledgment confirms voluntary execution, while a jurat includes an oath or affirmation about the document.

The definitions and requirements appear in the Supreme Court’s 2004 Rules on Notarial Practice, as amended.

Personal appearance and signing requirements

For ordinary paper notarization, the affiant must personally appear before the notary at the time of notarization. For a jurat, the affiant must sign in the notary’s presence and take an oath or affirmation.

A notary should refuse to act when, among other reasons:

The affiant is absent.
Identity cannot be established properly.
The document or notarial certificate is incomplete.
The notary knows or has good reason to believe that the transaction is unlawful.
The affiant does not understand the act or is not acting freely.
The notary has a prohibited interest or relationship under the rules.
The notary’s commission or territorial authority does not cover the act.

Sending a signed affidavit through a relative, messenger, fixer, or law-office employee is not a substitute for appearance. A video call alone is likewise not ordinary paper notarization; a valid remote electronic notarization must comply with the separate electronic-notarization rules.

At the time of a paper notarization, the affiant ordinarily signs or places a thumbmark or other mark in the notarial register. The register should contain the date and time, type of act, description of the document, the principal’s details, identity evidence, fee, and other required information.

What identification should you bring?

If the notary does not personally know the affiant, identity must be established through competent evidence of identity. The general rule recognizes:

At least one current identification document issued by an official agency bearing the holder’s photograph and signature; or
The oath or affirmation of qualified credible witnesses meeting the requirements of the Notarial Rules.

Bring the original ID, not merely a photograph or photocopy. A notary or receiving agency may reasonably request another ID or supporting record when names, signatures, addresses, or other details do not match.

A community tax certificate or cedula by itself is not competent evidence of identity under the present Notarial Rules because it ordinarily does not contain both a photograph and signature. The Supreme Court has specifically explained this point in decisions applying the rules, including Baylon v. Almo.

If you have no qualifying ID, ask the notary in advance whether identity can lawfully be established through credible witnesses. Do not borrow an ID, alter an expired ID, or ask the notary to enter an ID that was never presented.

Prepare the affidavit before notarization

1. Confirm the recipient’s requirements

Ask the court, prosecutor’s office, government agency, school, bank, insurer, employer, or other recipient for its current checklist or prescribed form. Confirm:

Whether an affidavit is actually required.
Whether the office has mandatory wording.
Who must execute it.
Whether witnesses or multiple affiants are required.
Which attachments and certified copies must accompany it.
Whether paper, electronic, or consular notarization is accepted.
The number of originals or copies.
The filing channel and deadline.
Whether documentary stamps or other charges apply.

There is no universal filing period for affidavits. Notarization does not pause, extend, or satisfy a deadline unless the governing rule expressly says so.

2. Write facts, not conclusions

State names, dates, places, events, amounts, communications, and actions precisely. Distinguish:

What you personally saw, heard, did, sent, received, or recorded.
What another person told you.
What a document shows.
What you infer but cannot personally confirm.

Avoid exaggeration, insults, guesses about another person’s intent, and legal labels unsupported by facts. If the exact date or amount is unknown, say so honestly and explain the basis of any approximation.

3. Review every page and attachment

Check that:

Names match the IDs and supporting records.
Dates and amounts are consistent.
Page numbers are complete.
Blank spaces are removed or properly crossed out.
Corrections are visible and properly initialed when permitted.
Every referenced attachment is present.
The jurat is appropriate and has enough space for the notary’s entries.

Do not ask a notary to notarize an affidavit with substantial blanks. If a material correction is needed after notarization, the safer course is usually to prepare and notarize a corrected affidavit rather than alter the completed document.

4. Appear with the original document and ID

Bring the unsigned affidavit unless instructed otherwise under a lawful procedure. Read it again before signing. Ask for an explanation if you do not understand the language; an oath should not be administered to someone who does not understand the document or the notarial act.

5. Inspect the completed notarial certificate

Before leaving, check for:

The date and place of notarization.
The notary’s signature and seal.
The affiant’s identity details where required.
The document, page, book, and series information for the notarial register.
A properly worded jurat rather than an acknowledgment, if the document is an affidavit.
The notary’s commission details.

Keep the receipt and obtain the number of original or certified copies required by the recipient.

Electronic and remote notarization

The Supreme Court’s 2025 Rules on Electronic Notarization recognize:

In-person electronic notarization;
Remote electronic notarization; and
Electronic notarization involving a paper document, as allowed by the rules.

A lawful electronic notarization must be performed by a commissioned Electronic Notary Public through the prescribed electronic-notarization framework. It is not accomplished simply by emailing a scanned signature, pasting an image of a notarial seal onto a PDF, or holding an informal video call.

Electronically notarized documents complying with the rules are legally recognized. However, practical acceptance can still depend on the receiving office, the document type, and any separate registration or filing rule. Confirm acceptance before paying or proceeding, particularly for land transactions, documents intended for use abroad, or offices that require an original paper instrument. The Supreme Court maintains an official eNotary information and FAQ page.

The amended paper-notarization rules also impose digital recordkeeping and reporting duties on notaries. They prohibit an additional charge solely for digitizing, transmitting, storing, or disposing of the required electronic copy. These duties do not authorize an uncommissioned person or an ordinary online service to perform notarization.

Affidavits signed outside the Philippines

For a document executed abroad and intended for use in the Philippines, first ask the Philippine recipient what it accepts. Depending on the country, purpose, and document, the recipient may require:

Notarization under the law of the place of execution followed by an apostille;
Authentication where the Apostille Convention does not apply;
Execution before a Philippine embassy or consulate; or
Compliant electronic notarization under the Philippine rules.

An apostille authenticates the origin of a foreign public document; it does not prove that every factual statement in the affidavit is true. Requirements also differ for countries and territories outside the Apostille Convention. Use the Department of Foreign Affairs’ official Apostille guidance and confirm the procedure with the receiving office.

Special affidavits may follow stricter rules

A general notarial jurat is not sufficient for every proceeding.

For example, affidavits submitted in a criminal preliminary investigation are governed by Rule 112 of the Rules of Criminal Procedure. They must generally be subscribed and sworn to before a prosecutor or authorized government official, and only in their absence or unavailability before a notary public. The administering officer must certify that the affiant was personally examined and voluntarily executed and understood the affidavit. See Rule 112, Section 3.

Judicial affidavits used as testimony are governed by the Judicial Affidavit Rule. They require a question-and-answer format, prescribed attestations, and compliance with filing and service periods. A short narrative affidavit notarized at a law office is not automatically a compliant judicial affidavit.

Agencies may also prescribe special forms for affidavits of loss, discrepancy, undertaking, support, guardianship, adverse claim, domestic relations, tax, immigration, land registration, procurement, or corporate matters. Follow the controlling rule and the current official checklist.

What notarization does—and does not do

Proper notarization generally converts a private document into a public document for evidentiary purposes and gives rise to a presumption of regularity in its execution. That presumption may be challenged with sufficient evidence.

Notarization does not:

Prove that every factual allegation is correct.
Transfer ownership by itself.
Cure fraud, forgery, incapacity, lack of authority, illegality, or a missing statutory formality.
Make an affidavit conclusive evidence.
Guarantee acceptance by a court or agency.
Replace required witnesses, attachments, registration, tax payment, filing, or service.

A defective notarization can strip a document of its public character and leave it as a private document requiring authentication. In transactions where a public instrument is required for validity—not merely convenience—the consequences can be more serious. The Supreme Court discusses these distinctions in Patenia-Kinatac-an v. Patenia-Decena.

Evidence to preserve

Keep:

The final notarized original and a clear scan of every page.
Copies of all exhibits exactly as attached.
The receipt and the notary’s contact and commission details.
Any electronic-notarization certificate, audit record, verification information, or official transaction reference.
The recipient’s checklist, submission confirmation, and stamped receiving copy.
Emails, text messages, photographs, CCTV requests, reports, contracts, receipts, bank records, and other materials supporting the sworn facts.
Earlier drafts when changes may later need explanation.

Preserve original electronic files and metadata where possible. Do not crop, edit, rename, or repeatedly resave the only copy of important digital evidence.

Common mistakes

Signing before meeting the notary.
Allowing another person to appear for the affiant.
Using an acknowledgment instead of a jurat.
Presenting only a cedula, expired ID, photocopy, or phone image of an ID.
Leaving material blanks.
Including facts supplied entirely by someone else without identifying the source.
Attaching incomplete or altered records.
Changing the affidavit after notarization.
Believing that notarization proves ownership or truth.
Using a generic online form without checking the recipient’s requirements.
Missing the filing deadline while trying to perfect the notarization.
Paying a fixer or accepting a notarial seal without personal appearance or a compliant electronic process.

False statements and fabricated notarization

Knowingly making a material false statement under oath can constitute perjury when the legal elements are present. Republic Act No. 11594 increased the penalties under Article 183 of the Revised Penal Code. Other possible liability may arise from falsification, use of falsified documents, fraud, obstruction, or offenses under special laws, depending on the conduct and evidence.

A false affidavit does not become lawful because a notary accepted it. Likewise, a forged seal, fabricated register entry, false identity, or notarization without appearance should be treated seriously.

When legal help is urgent

Consult a Philippine lawyer promptly when:

The affidavit concerns a criminal complaint, counter-affidavit, arrest, subpoena, or preliminary investigation.
A court, prosecutor, or agency deadline is near.
The document affects land, inheritance, marriage, children, immigration status, employment termination, a large debt, or substantial property.
Someone asks you to sign facts you do not know or wording you do not understand.
Your signature, ID, or notarized document may have been forged or misused.
A material statement in an already filed affidavit is wrong.
You are being pressured, threatened, or induced to execute an affidavit of desistance, waiver, quitclaim, or admission.
The document was notarized without your appearance.
A foreign authority or Philippine recipient disputes the authentication or electronic notarization.

Do not destroy or alter the questioned document. Secure originals, scans, communications, payment records, and details of the persons involved.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily sworn or affirmed before an authorized officer. But the precise requirement depends on the law, rule, or receiving office. Some submissions use verified declarations, certifications, or agency forms with different execution requirements.

Can I sign an affidavit before going to the notary?

For an ordinary jurat, no. You should sign in the notary’s presence because the notary must witness the signing and administer the oath or affirmation.

Is one government ID enough?

The general rule recognizes at least one current official ID bearing both photograph and signature. A second ID or supporting document may reasonably be requested when identity details are inconsistent or doubtful.

Can a notary accept a cedula as the only ID?

Ordinarily, no. A community tax certificate lacking both photograph and signature is not competent evidence of identity under the Notarial Rules.

Can another person have my affidavit notarized for me?

No. Personal appearance is essential, except that a properly conducted remote electronic notarization may satisfy appearance under the separate electronic rules.

Does notarization make the affidavit automatically true?

No. Notarization establishes the formal notarial act and supports authenticity and due execution. The statements may still be contradicted and evaluated with the other evidence.

How much does notarization cost?

There is no single nationwide retail price applicable to every affidavit and circumstance. Fees may depend on the document, location, applicable schedules, and professional work requested. Ask for the fee and a receipt before proceeding. Drafting or legal advice is distinct from the notarial act.

Is there a deadline for notarizing an affidavit?

There is no universal deadline. The controlling deadline is usually the deadline for filing, submitting, serving, registering, or using the affidavit. Obtain the recipient’s current rule or written checklist immediately.

Can I correct a notarized affidavit?

Do not erase, overwrite, replace pages, or silently modify it. For a material error, prepare a corrected or supplemental affidavit and comply with the receiving office’s procedure. If the original has already been filed, obtain legal advice promptly.

Can an affidavit be notarized online?

Yes, but only through a procedure compliant with the 2025 Rules on Electronic Notarization and by a properly commissioned Electronic Notary Public. An ordinary video call or pasted digital seal is not enough.
