Quick answer

An affidavit is a written statement of facts that the person making it—the affiant—swears or affirms to be true. For a conventional paper affidavit to be properly notarized in the Philippines, the affiant must generally:

Read and understand the completed affidavit.
Personally appear before a duly commissioned notary public.
Present competent evidence of identity unless personally known to the notary.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its contents are true.
Sign or place the required mark in the notarial register.

The notary then completes the jurat, records the transaction, and affixes the notary’s signature and official seal. Sending a signed affidavit through a messenger, asking someone else to “process” it, or appearing only through an ordinary video call does not satisfy conventional notarization requirements.

Notarization does not establish that every statement in an affidavit is true. It establishes that the identified affiant personally appeared, signed, and swore or affirmed to the document under the applicable procedure. A knowingly false material statement may expose the affiant to criminal, civil, administrative, or procedural consequences.

What an affidavit should contain

There is no single form suitable for every purpose. The receiving court, prosecutor, government agency, bank, employer, or private institution may prescribe its own wording, attachments, number of copies, or filing procedure.

A usable affidavit ordinarily contains:

A title identifying its purpose, such as “Affidavit of Loss,” “Affidavit of Support,” or “Complaint-Affidavit.”
The affiant’s complete name and relevant personal details.
A clear statement that the affiant is competent to testify and is making the affidavit voluntarily.
Numbered factual allegations, preferably in chronological order.
Facts within the affiant’s personal knowledge.
Identification of documents, photographs, messages, receipts, or other attachments.
The purpose for which the affidavit is executed.
The affiant’s signature.
A properly completed jurat.
The notary’s commission and notarial details.

Use precise facts rather than conclusions. State who did what, when, where, and how. If a statement came from another person or record, identify that source rather than presenting it as personal knowledge.

Do not sign an affidavit containing blank spaces, unfinished paragraphs, inconsistent dates, or unidentified attachments.

The affiant must understand the document

A notary must not proceed if the affiant does not understand the nature or consequences of the transaction. The notary must also refuse if there is reason to believe that the affiant is being coerced, is acting involuntarily, or lacks the capacity to understand the document.

If the affidavit is written in a language the affiant does not understand, it should be translated or accurately explained before signing. The document may need an interpreter’s certification or affidavit, depending on its intended use.

An affiant who cannot read, write, hear, speak, or sign may still be able to execute an affidavit through an appropriate mark, interpreter, or other procedure. Because the exact safeguards depend on the person’s condition and the document, inform the notary in advance and bring a competent, disinterested interpreter or witness if requested.

Personal appearance is indispensable

Under the 2004 Rules on Notarial Practice, conventional notarization requires the affiant to be in the notary’s physical presence at the time of the notarial act.

The notary should not:

Notarize a document already signed outside the notary’s presence when a jurat is required.
Rely on another person’s assurance that the signature is genuine.
Notarize for an absent spouse, principal, corporate officer, or relative.
Allow a representative to take the affiant’s oath.
Use a previously supplied signature page.
Complete a jurat by telephone, messaging application, or ordinary video conference.

The Supreme Court has repeatedly emphasized that notarization is not an empty formality. It converts a private document into a public document entitled to evidentiary treatment under the rules, so identity, voluntariness, and personal appearance must be carefully verified. See, for example, Gaddi v. Velasco, A.C. No. 8637, September 15, 2014.

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
Professional Regulation Commission ID
NBI clearance
Police clearance
Postal ID
Voter’s ID
GSIS e-card
SSS card
PhilHealth card
Senior citizen ID
OWWA or OFW ID
Seaman’s book
Alien Certificate of Registration
Government-office ID
Other qualifying government-issued identification

The complete rule is in the Supreme Court’s February 19, 2008 amendment on competent evidence of identity.

A document should not be assumed sufficient merely because it contains an identification number. The ID should be current and should satisfy the applicable photograph-and-signature requirements. A community tax certificate or cedula alone is generally not the safe equivalent of competent evidence of identity under the current rule.

If the affiant has no qualifying ID, the rules allow identification through the oath or affirmation of credible witnesses under defined conditions. This is not simply a matter of bringing any two companions. The witnesses must meet the rule’s personal-knowledge and identification requirements. Confirm the arrangement with the notary before going to the office.

Bring the original ID, not merely a screenshot or photocopy. The notary may record the ID’s type, number, place or date of issue, or other identifying particulars.

Jurat and acknowledgment are different

An affidavit ordinarily requires a jurat, not an acknowledgment.

In a jurat:

The affiant personally appears.
The affiant signs in the notary’s presence.
The affiant takes an oath or affirmation that the statements are true.

In an acknowledgment:

The signer personally appears.
The signer declares that the signature was voluntarily affixed for the purposes stated in the instrument.
If signing in a representative capacity, the signer declares that he or she has authority to act.

Acknowledgments are commonly used for deeds, contracts, powers of attorney, and similar instruments. A jurat is generally used for affidavits, verified pleadings, and other sworn statements.

A document cannot safely be converted from one notarial act to another merely by changing the rubber stamp. The certificate must correspond to the act actually performed and to the requirement of the receiving office.

What happens during conventional notarization?

A careful paper-notarization process generally follows these steps:

Document review. The notary checks whether the document is complete, lawful on its face, and suitable for the requested notarial act.
Identity verification. The affiant presents the original qualifying ID or complies with the credible-witness procedure.
Assessment of capacity and voluntariness. The notary confirms that the affiant understands the document and is acting freely.
Signing. For an affidavit requiring a jurat, the affiant signs in the notary’s presence.
Oath or affirmation. The affiant swears or affirms that the statements are true.
Register entry. The notary records the act and requires the affiant to sign or mark the notarial register as applicable.
Completion of the jurat. The notary enters the venue, date, identification particulars, notarial details, signature, and official seal.
Recordkeeping and electronic-copy compliance. The notary keeps and submits the records required by the amended rules.

The notarial certificate should not be blank or incomplete when the document is released. Check the date, place, document number, page number, book number, series, notary’s name, commission details, signature, and seal.

Electronic notarization is a regulated alternative

The Supreme Court has adopted the Rules on Electronic Notarization, A.M. No. 24-10-14-SC. Electronic notarization is not the same as sending a scanned signature to a lawyer or joining an informal video call.

A valid electronic notarial act must comply with the Supreme Court’s system, registration, identity-verification, electronic-signature, electronic-seal, audiovisual, recording, territorial, and recordkeeping requirements. Only a properly authorized electronic notary using the prescribed platform and procedure may perform it.

Availability may depend on the Supreme Court’s operational rollout, accredited facilities, registered electronic notaries, and whether the particular document is eligible. If a remote service is offered, verify that it operates under the Supreme Court’s electronic-notarization framework. A claim that a document can be “online notarized” through email or a messaging application alone is a warning sign.

The temporary remote-notarization rules adopted during the COVID-19 public-health emergency should not be treated as permanent authority for informal remote notarization.

The 2025 amendments and electronic copies

The Supreme Court amended the conventional notarial rules in 2025 to strengthen digital reporting, record preservation, and safeguards. Among other requirements, notaries must create prescribed electronic reproductions of covered documents, electronically transmit required duplicate originals to the clerk of court, and provide signatories with electronic copies within the period and under the conditions stated in the amended rules.

A signatory should ordinarily provide a working email address or agree with the notary on another permitted electronic transmission method. The notary may not impose an additional charge merely for required digitization, transmission, storage, or related processing.

If the electronic copy materially differs from the signed paper document, notify the notary promptly in writing and preserve both versions. The official text is available in the Supreme Court’s 2025 amendments to the 2004 Rules on Notarial Practice.

Not every affidavit is filed or sworn in the same way

The general notarial rules do not replace special procedural requirements.

Complaint-affidavits in preliminary investigation

Under Rule 112 of the Rules of Criminal Procedure, complaint-affidavits and supporting affidavits submitted for preliminary investigation must be subscribed and sworn to before a prosecutor or government official authorized to administer oaths—or, if none is available, before a notary public. The officer must certify that the affiant was personally examined and voluntarily executed and understood the affidavit.

A standard notarial jurat may therefore be insufficient if the special Rule 112 certification or examination was not performed. Consult the receiving prosecutor’s office before execution. See the Rules of Criminal Procedure, particularly Rule 112.

Judicial affidavits

A Judicial Affidavit is governed by the Judicial Affidavit Rule and follows a question-and-answer form with an examining lawyer’s sworn attestation. It is not interchangeable with an ordinary narrative affidavit. The court’s order and procedural rules must be checked for applicability and filing deadlines.

Verified pleadings and certifications

A verification, certification against forum shopping, or other sworn pleading must follow the Rules of Court and any special statute or tribunal rule. The correct person must sign it. An unauthorized employee or lawyer cannot automatically sign for a party or corporation.

Government-agency forms

The PSA, LTO, SEC, BIR, Bureau of Immigration, Registry of Deeds, schools, banks, insurers, and other institutions may require their own form, particular supporting records, recent execution, witnesses, or multiple originals. Obtain the current form before notarization.

Documents executed abroad

An affidavit signed abroad should generally be sworn before a Philippine embassy or consulate or before a competent foreign notarial authority. If notarized by a foreign authority, authentication or an Apostille may be required for Philippine use, depending on the country, treaty status, receiving office, and document.

Documents for use abroad

A Philippine notarization does not by itself guarantee acceptance in another country. The destination may require an Apostille, consular authentication, certified translation, or a particular form. Confirm the requirements with the foreign receiving authority and the Department of Foreign Affairs before execution.

Does every affidavit need notarization?

A document described as an affidavit is ordinarily expected to be sworn or affirmed before an authorized officer. Without the oath or affirmation, it may be treated only as an unsworn written statement unless a statute, rule, or authorized electronic procedure provides otherwise.

Not every private document or contract, however, must be notarized to be valid. Some contracts are binding between the parties once the essential requirements are present, even if they remain private documents. Other transactions must appear in a public document for enforceability, registration, or compliance; in a few cases, the required form is essential to validity.

For example:

Transactions affecting real rights over immovable property are generally among those that should appear in a public document under Article 1358 of the Civil Code.
A donation of immovable property must satisfy the public-document and acceptance requirements of Article 749.
Wills have distinct statutory formalities that ordinary notarization cannot replace.
Deeds intended for registration require the form and acknowledgment accepted by the Registry of Deeds.

The relevant provisions are in the Civil Code of the Philippines. Have high-value property, inheritance, corporate, or family documents reviewed before signing.

Does notarization make the statements true?

No. Notarization does not conclusively prove the truth of the affidavit’s factual assertions, validate an illegal transaction, cure the signer’s lack of authority, or transfer rights that the signer does not possess.

A notarized affidavit may still be challenged based on:

False or misleading statements
Forgery or impersonation
Lack of personal appearance
Coercion, fraud, or incapacity
Lack of authority to represent another person or entity
An incomplete or defective jurat
An expired or territorially invalid notarial commission
Noncompliance with a special procedural rule
Hearsay or lack of personal knowledge
Failure to attach or authenticate supporting documents

Notarization gives a document significant evidentiary character, but it does not prevent a court or agency from examining its authenticity, admissibility, weight, or truthfulness.

Risks of a false affidavit

Do not sign an affidavit merely because another person says it is “only for compliance.” Read every paragraph and correct anything inaccurate.

Depending on the circumstances, knowingly making a false material statement under oath may lead to prosecution for perjury or another applicable offense. The exact charge depends on the wording, materiality, purpose, administering officer, venue, and use of the affidavit. Forging a signature, altering a notarized document, using a falsified affidavit, or impersonating an affiant may involve separate offenses.

A false affidavit may also result in:

Dismissal or weakening of a complaint, defense, or application
Contempt or procedural sanctions
Civil liability
Employment or professional discipline
Cancellation of a benefit, permit, registration, or transaction
Adverse credibility findings in later proceedings

Correct an honest mistake promptly through an appropriate supplemental, corrective, or amended affidavit. Do not alter a notarized original by erasure, insertion, or page substitution.

Evidence to preserve

Keep:

The final signed and notarized original
The electronic copy sent by the notary
A clear copy of the ID presented
Drafts showing material corrections
All referenced attachments
Emails or messages arranging the notarization
Receipts for lawful fees
Filing receipts, acknowledgment emails, or stamped receiving copies
The name and office address of the notary
Photographs or records relevant to voluntariness or personal appearance, if a dispute is anticipated

If the affidavit relates to a crime, accident, threat, property dispute, employment claim, fraud, or online transaction, preserve the underlying evidence in its original form. Do not rely solely on screenshots when exportable messages, source files, transaction records, CCTV footage, metadata, or certified records are available.

How to check the notarization

Before leaving the notary’s office:

Confirm that every page and attachment belongs to the document.
Check that names, dates, addresses, and ID particulars are correct.
Make sure no material blank remains.
Confirm that the jurat states the correct city or municipality and date.
Look for the notary’s signature and clear official seal.
Check the commission number and validity period.
Check the document, page, book, and series numbers.
Obtain your signed original and required electronic copy.
Ask how a certified copy or notarial-register entry may later be verified.

A notary generally exercises authority only within the territorial jurisdiction stated in the commission. A document purportedly notarized at a place where the notary was not authorized—or on a date when the commission was not valid—should be investigated.

Common mistakes to avoid

Signing before going to the notary when a jurat is required
Sending only a representative or messenger
Using an expired, altered, borrowed, or purely private ID
Treating a cedula alone as sufficient identification
Signing an affidavit the affiant cannot understand
Leaving dates, amounts, names, or factual paragraphs blank
Attaching documents after notarization without proper identification
Using acknowledgment wording for an affidavit that requires a jurat
Assuming any lawyer is automatically a commissioned notary
Using a notary outside the notary’s territorial jurisdiction
Accepting informal “online notarization”
Altering or replacing pages after the notarial act
Assuming notarization cures an unlawful agreement or lack of authority
Filing an ordinary affidavit when a Judicial Affidavit or special agency form is required
Missing the filing deadline while focusing only on notarization

Practical checklist

Before visiting the notary:

Obtain the current form or filing instructions from the receiving office.
Prepare a complete, accurate draft.
Organize and label all attachments.
Bring the original of a current government-issued photo-and-signature ID.
Bring the unsigned document if it requires a jurat.
Bring all persons whose signatures must be notarized.
Bring proof of authority if signing for a corporation, partnership, estate, minor, or principal.
Confirm the notary’s office, commission, territorial jurisdiction, fee, and electronic-copy procedure.
Ask whether witnesses, interpreters, photographs, or additional records are required.
Note the filing deadline separately from the notarization date.

After notarization:

Inspect the completed jurat and seal.
Secure the original.
Save the notary’s electronic copy.
Report any discrepancy promptly in writing.
File the document with the correct office and preserve proof of filing.

When legal help is urgent

Consult counsel promptly if:

You are being pressured to sign an affidavit you believe is false or incomplete.
Someone notarized or used a document without your personal appearance.
Your signature, ID, or notarial details were forged or misused.
The affidavit involves a pending criminal complaint, inquest, preliminary investigation, court case, or expiring deadline.
You may incriminate yourself or waive a legal right.
The affidavit concerns a transfer of land, inheritance, corporate authority, custody, immigration status, or a substantial financial obligation.
Different versions of the document exist.
The notary refuses to give identifying or record information.
You need to withdraw, correct, or explain a previously filed affidavit.

An affidavit of desistance, waiver, quitclaim, confession, settlement, or admission deserves particular caution. Its title does not determine its legal effect, and notarization does not guarantee that the court, prosecutor, agency, or other party will accept it.

Frequently asked questions

Can I sign the affidavit at home and have someone bring it to the notary?

Not for a conventional jurat. The affiant must personally appear, sign in the notary’s presence, and take the oath or affirmation.

Can the notary accept a photocopy or phone image of my ID?

Do not assume so. Bring the original current government-issued ID. The notary must be able to verify identity reliably and may require additional proof.

Is a cedula enough?

A community tax certificate alone should not be relied upon as competent evidence of identity under the current notarial rules. Bring a current official ID bearing your photograph and signature.

Can a relative appear or sign for me?

A representative cannot take your oath or swear that your personal statements are true. If the document involves an authorized representative, the authority and correct type of notarial act must be separately established.

Is an affidavit valid forever?

An affidavit does not ordinarily expire merely because time passes, but the receiving institution may require a recently executed affidavit. Changed circumstances may also make an older statement inaccurate.

Are witnesses always required?

Not for every affidavit. Witnesses may be required by a special law, form, agency, transaction, the affiant’s condition, or the credible-witness identity procedure.

Does the notary have to prepare the affidavit?

No. A notary may notarize a properly prepared document without having drafted it, provided all legal requirements are satisfied. Drafting or legal review is a separate professional service.

Can any lawyer notarize a document?

No. The lawyer must hold a valid notarial commission for the relevant territorial jurisdiction and perform the act within that authority.

Is electronic notarization now legal?

Yes, but only through the regulated Supreme Court framework and by an authorized electronic notary following the prescribed system. Emailing a scan or joining an ordinary video call is not enough.

Can I cancel a notarized affidavit?

Notarization cannot simply be erased. Depending on whether the affidavit has been submitted or relied upon, the affiant may need a corrective, supplemental, or withdrawal affidavit and must notify the receiving office. Legal consequences already produced may not automatically disappear.

Where can misconduct by a notary be reported?

Possible remedies include raising the matter before the Executive Judge who commissioned the notary and, where professional misconduct is involved, using the applicable lawyer-disciplinary process. Forgery, impersonation, or use of falsified documents may also warrant a complaint before law-enforcement or prosecutorial authorities. Preserve the original document and obtain legal advice before surrendering it.
