Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. To be a valid affidavit, the affiant must:

State truthful, relevant facts—normally facts within the affiant’s personal knowledge.
Sign and swear to the affidavit before a commissioned notary public or another officer specifically authorized to administer the oath.
Personally appear before that officer through the legally permitted mode.
Prove identity using competent evidence of identity.
Present a complete document without unfilled material blanks.

For a traditional paper affidavit, the affiant should sign in the physical presence of the notary because the required notarial act is ordinarily a jurat. Sending an already signed document through a relative, messenger, or fixer is not a valid substitute for personal appearance.

Electronic and remote notarization is now legally recognized, but only for qualifying electronic documents processed by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. An ordinary video call, emailed scan, or pasted image of a seal is not enough.

What makes a document an affidavit?

A document is not an affidavit merely because it is titled “Affidavit.” Its essential features are:

An identifiable affiant.
Statements of fact attributed to that affiant.
The affiant’s signature.
An oath or solemn affirmation administered by a competent officer.
A proper jurat or other certificate showing that the oath was administered.

If no oath or affirmation was administered, the document may still be a signed statement, declaration, or private document—but it is not ordinarily a sworn affidavit.

The exact contents depend on the affidavit’s purpose. An affidavit of loss, complaint-affidavit, affidavit of support, judicial affidavit, affidavit for a civil-registry proceeding, and affidavit used in a land transaction do not have interchangeable requirements.

Jurat versus acknowledgment

The correct notarial act matters.

Notarial act	What the signer does	Common use
Jurat	Appears before the notary, signs the document in the notary’s presence, and takes an oath or affirmation that its contents are true	Affidavits, sworn statements, verifications
Acknowledgment	Appears before the notary and declares that an existing signature was voluntarily affixed and that the document is the signer’s free act and deed	Deeds, contracts, powers of attorney and similar instruments

An affidavit ordinarily needs a jurat, not a mere acknowledgment. The Supreme Court has disciplined notaries for using the wrong certificate and has emphasized that a jurat states that the document was subscribed and sworn to before the notary. See the Court’s discussion in Gonzales v. Ramos.

What to put in an affidavit

Unless an agency, court, or statute supplies a required form, a properly prepared affidavit commonly contains:

The correct venue, identifying the country and city or municipality where the oath will actually be administered.
The affiant’s full legal name and relevant personal details.
A statement that the affiant is of legal age or otherwise competent to testify.
A clear explanation of how the affiant knows the facts.
Separately numbered factual statements in chronological or logical order.
Exact names, dates, places, amounts, document numbers, and other material details when known.
Careful qualifications such as “based on the attached record” when the fact comes from an authentic record rather than personal observation.
Identification and description of attachments or annexes.
The purpose for which the affidavit is executed, if relevant.
The affiant’s signature over the printed name.
A jurat to be completed and signed by the notary or authorized officer.

Do not state guesses, legal conclusions copied from a template, or another person’s account as though personally witnessed. If information came from a record, message, photograph, or named person, say so accurately and attach or preserve the source when appropriate.

Traditional paper notarization requirements

Traditional notarization of paper documents remains governed by the 2004 Rules on Notarial Practice, as amended, including the 2025 amendments on digital reporting and safeguards.

Bring a complete document

The affidavit should be final and integrally complete. A notary should not notarize:

A blank or materially incomplete document.
A document containing unexplained empty spaces that can later be filled in.
A document that appears unlawful or immoral.
A document the affiant does not appear to understand.
A document signed through coercion or without sufficient capacity.

Attach every annex referred to in the affidavit. Number the pages and annexes consistently. If corrections are unavoidable, make them clearly and have the affiant and notary address them properly; material changes are better handled by preparing a clean final document.

Appear personally

The affiant must personally appear before the notary at the time of the jurat. The notary must be able to confirm the affiant’s identity, capacity, voluntariness, signature, and oath.

For a joint affidavit, every affiant covered by the jurat must appear and take the oath. One person cannot appear for an absent co-affiant. If the affiants cannot attend together, ask whether separate affidavits or separately completed notarial certificates will be accepted.

Present competent evidence of identity

If the affiant is not personally known to the notary, the usual requirement is at least one current identification document issued by an official agency that bears both the affiant’s photograph and signature. Examples in the amended rules include passports, driver’s licences, PRC IDs and various government-issued identification documents, provided the particular document is current and actually contains the required photograph and signature.

Bring the original ID, not merely a screenshot or photocopy. A notary may reasonably request additional identification when there is a discrepancy or doubt.

A community tax certificate or cedula alone is not competent evidence of identity under the current rules because it does not satisfy the photograph-and-signature requirement. The Supreme Court applied this rule in Dandoy v. Edayan.

When acceptable documentary identification is genuinely unavailable, the rules provide a limited credible-witness method:

One credible witness who is not a party to the document or transaction, is personally known to the notary, and personally knows the affiant; or
Two credible witnesses who are not parties to the document or transaction, each personally knows the affiant, and each presents the required documentary identification.

A relative, buyer, beneficiary, attorney-in-fact, or other person directly involved in the transaction may be disqualified from serving as the required disinterested identity witness.

Sign and take the oath

For a paper affidavit requiring a jurat, wait for the notary’s instruction before signing. The affiant must then take an oath or solemn affirmation. A solemn affirmation is legally available to a person who does not wish to take a religious oath.

The notary must personally perform the notarial act. Office staff may prepare entries or receive documents, but they cannot administer the oath, sign for the notary, or apply the notary’s seal independently.

Sign the notarial register

The notary must record the act in the notarial register at the time of notarization. The entry should include, among other matters:

The entry and page numbers.
Date and time of the act.
Type and title of the document.
Name and address of the affiant.
Identity evidence or credible-witness details.
Fee charged.
Any relevant circumstances.

The affiant is ordinarily required to sign or place the appropriate mark in the register. A purported notarization that cannot be found in the notarial records may be challenged and loses much of the reliability associated with regular notarization.

Check the completed jurat

Before leaving, confirm that the affidavit shows:

The correct place and date of notarization.
A statement that the affiant personally appeared, signed, and took the oath.
The identification details required for the transaction.
The notary’s signature and visible official seal.
Document, page, book, and series numbers.
The notary’s commission and professional details.

Never accept a loose seal, blank jurat, pre-signed notarial certificate, backdated certificate, or promise that the details will be completed later.

Who may administer the oath?

Most private affidavits are sworn before a lawyer holding a valid notarial commission for the relevant territorial jurisdiction.

Judges, clerks of court, consular officers, prosecutors, and certain other public officers may administer oaths when a law or their official functions authorize them to do so. Their authority is not necessarily available for every private transaction. Follow the instructions of the court or agency receiving the affidavit.

A lawyer is not automatically authorized to notarize merely because the person is a member of the Bar. The lawyer must hold a current notarial commission, unless acting under a separate lawful authority.

A notary is also disqualified when the notary is a party to or directly benefits from the transaction, or when the principal is the notary’s spouse, common-law partner, ancestor, descendant, or relative within the degree prohibited by the rules.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, have been effective since March 24, 2025. They supplement rather than replace traditional notarization.

What is covered?

The rules cover electronic documents notarized through:

In-Person Electronic Notarization: The parties physically appear before the Electronic Notary Public but sign and process an electronic document through the accredited facility.
Remote Electronic Notarization: The parties appear synchronously by videoconference through the accredited facility.

The electronic document must meet the facility’s prescribed format, generally PDF or PDF/A. The notary and users must use a Supreme Court-accredited Electronic Notarization Facility, or ENF.

Requirements for a remote electronic jurat

For an electronic jurat, the Electronic Notary Public must:

Verify the identities of the principal and any witnesses through the facility’s identity-verification system.
Confirm the principal’s location and voluntariness.
Ensure the principal remains visible during the session.
Require the principal to affix the electronic signature through the facility in the notary’s full view.
Administer the oath.
Complete and attach the electronic notarial certificate, electronic signature, and electronic seal.
Record and transmit the notarial act as required by the rules.

Pre-recorded signing videos are prohibited. An ordinary Zoom, Messenger, Viber, or similar video call outside an accredited facility does not satisfy the electronic-notarization rules.

The legal framework is in force, but actual access depends on the availability of a commissioned Electronic Notary Public and an accredited facility. Verify providers through the Supreme Court’s eNotary Services page and directory before paying or uploading personal documents.

What is not covered?

The electronic-notarization rules do not apply to:

Notarial wills.
Deposition taking.
Paper documents bearing wet signatures or handwritten marks.

The 2020 interim rules that permitted remote notarization of paper documents have been repealed. A scan of a wet-signed paper affidavit cannot be turned into a valid remote notarization merely by emailing it to a notary.

Parties outside the Philippines

Remote electronic notarization for a principal abroad is narrowly allowed only when the principal is physically within the premises of a Philippine embassy, consular office, or office of a Philippine Honorary Consul, with the required location confirmation.

Otherwise, a person abroad will commonly need to use:

A Philippine embassy or consulate’s notarial service; or
A competent local foreign notary, followed by an apostille or authentication when required.

Requirements vary by country and receiving agency. Personal appearance and original identity documents are generally required for Philippine consular notarization.

Apostille and authentication

Notarization and apostille are different processes.

Notarization confirms the notarial act, identity, appearance, signature, oath, or acknowledgment.
Apostille authenticates the origin of a public document for use in another Apostille Convention country. It does not prove that every factual statement in the affidavit is true.

For a Philippine notarized private document intended for use abroad, the DFA generally requires a Certificate of Authority for a Notarial Act, or CANA, issued by the appropriate Regional Trial Court before apostille processing. Check the current DFA Apostille documentary requirements and the destination country’s requirements before notarization.

Apostille is generally unnecessary for an affidavit used only within the Philippines unless the receiving authority specifically requires another authentication step.

What notarization does—and does not do

Regular notarization gives a private document public character and evidentiary advantages concerning its authenticity and due execution. Courts generally accord a regularly notarized document a disputable presumption of regularity.

It does not:

Guarantee that every statement is factually true.
Cure an illegal transaction.
establish that the affiant has personal knowledge of every assertion.
Make inadmissible evidence admissible for every purpose.
Prevent another party from challenging forgery, fraud, coercion, incapacity, or defective notarization.
Replace substantive requirements imposed by a statute, court, or agency.

A defective notarization generally strips a document of its public character and reduces it to a private document requiring proof of authenticity. It does not automatically void every underlying transaction, although the result may be invalidity where a public instrument or sworn form is required for validity. See Sps. Alcantara v. Nido and Heirs of Magpily v. De Jesus.

Deadlines and validity periods

There is no universal deadline or expiration period applicable to every affidavit. The controlling deadline comes from the proceeding or transaction for which it will be used.

An agency may require an affidavit executed within a stated number of months, even though affidavits do not automatically expire as a general category. An older affidavit may also become unreliable when circumstances have changed.

A judicial affidavit is a special court document governed by the Judicial Affidavit Rule, not an ordinary narrative affidavit. Under its general timetable:

Judicial affidavits and exhibits are filed and served no later than five days before the relevant pre-trial, preliminary conference, or scheduled hearing.
In covered criminal cases, the prosecution generally submits its judicial affidavits no later than five days before pre-trial.
An accused choosing to submit judicial affidavits generally has ten days from receiving the prosecution affidavits.
Late or defective submissions may be excluded, subject to the Rule’s limited one-time relief for a valid reason, absence of undue prejudice, and the prescribed fine.

Special rules and court orders may alter what is required in a particular case. Treat the deadline stated in a summons, subpoena, agency notice, order, or official checklist as controlling unless a lawyer or the issuing authority confirms otherwise.

Evidence to preserve

Keep the following securely:

The final notarized original and a clear, complete scan.
Every annex in the exact form submitted.
The factual records used to prepare the affidavit.
Proof of filing or submission, including the receiving copy, email acknowledgment, tracking record, or portal receipt.
The notary’s name, office address, commission details, receipt, and notarial register numbers.
Appointment and payment records.
For electronic notarization, the electronically signed original—not merely a printout—the validation data, facility receipt, and any downloadable official session record.

Do not alter the affidavit after notarization. If a material error is discovered, consult the receiving authority or a lawyer about executing a corrected, supplemental, or withdrawal affidavit. Never erase, overwrite, substitute a page, or silently replace an annex.

If notarization appears suspicious, request verification from the Office of the Clerk of Court of the Regional Trial Court where the notary was commissioned. For foreign use, a CANA may provide the required official confirmation.

Common mistakes to avoid

Signing a paper affidavit before meeting the notary.
Allowing another person to deliver the affidavit for notarization.
Using only a cedula or an expired ID.
Leaving material blanks for later completion.
Copying allegations the affiant cannot honestly verify.
Using an acknowledgment where a jurat is required.
Failing to attach annexes mentioned in the affidavit.
Using inconsistent names, dates, addresses, or document numbers.
Asking a notary to backdate the document.
Editing or replacing pages after notarization.
Using an uncommissioned lawyer, fake seal, or fabricated register entry.
Treating an ordinary video call as electronic notarization.
Assuming an apostille replaces notarization.
Assuming notarization proves the truth of the allegations.
Relying on a generic online template despite a court or agency’s mandatory form.

False statements and possible liability

An affiant should read every sentence before taking the oath. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making an untruthful sworn statement or affidavit on a material matter before an authorized officer, when required by law or made for a legal purpose, may constitute perjury.

The amended statutory penalty reaches prision mayor in its minimum through medium periods—six years and one day to ten years. The law also contains additional provisions on fines, disqualification, and offenses committed by public officers. Criminal liability is not established by a mere mistake: the exact statement, materiality, knowledge, intent, legal purpose, timing, and surrounding evidence must be proved.

A false or forged notarized document may also raise separate issues involving falsification, fraud, contempt, administrative liability, or professional discipline.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A court, prosecutor, immigration office, regulator, or government agency has set a deadline.
The affidavit concerns criminal accusations, property, inheritance, corporate control, citizenship, child custody, marriage, substantial money, or waiver of rights.
You are being pressured to sign facts you do not understand or believe.
Someone asks you to sign a blank document or agree to backdating.
The affiant has limited capacity, cannot read the document, or needs an interpreter.
A material error has already been filed or submitted under oath.
A signature, seal, commission number, or register entry appears forged.
The document states that a deceased, absent, or unidentified person appeared before the notary.
Another person used your identity or signature.
Immediate protection or preservation of evidence may be necessary.

Frequently asked questions

Does every affidavit have to be notarized?

An affidavit must be sworn or affirmed before an officer legally authorized to administer the oath. That officer is commonly a notary public, but a statute, court rule, or agency procedure may authorize another officer.

Can I sign the affidavit before going to the notary?

For a traditional jurat, sign in the notary’s presence. If it was signed earlier, the notary may require a fresh signature or a properly re-executed document.

Is one ID enough?

The rules permit at least one current official identification document bearing both photograph and signature, but the notary may reasonably request more when names, signatures, appearance, or other details do not match.

Is a cedula a valid notarial ID?

Not by itself. A community tax certificate does not meet the current photograph-and-signature requirement for competent evidence of identity.

Can an affidavit be notarized online?

Yes, if it is a qualifying electronic document notarized by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. An emailed scan or ordinary video call is insufficient.

Does an affidavit expire?

There is no universal expiration rule. The receiving court, agency, bank, school, employer, or foreign authority may impose a recency requirement, and changed facts may make an older affidavit unusable.

Does the notary confirm that the affidavit is true?

The notary administers the oath and verifies matters such as identity, appearance, signature, capacity, voluntariness, and document completeness. The notary does not ordinarily investigate and guarantee every factual allegation.

Can a close relative notarize my affidavit?

The rules disqualify a notary in specified close-family relationships and when the notary is a party to or directly benefits from the transaction. Use an independent commissioned notary.

How much should notarization cost?

Separate the fee for the notarial act from any professional fee for drafting, consultation, travel, document review, or other services. Ask for an itemized amount and receipt. The 2025 amendments prohibit notaries from imposing additional charges for digitization and transmission required by those amendments.

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

Do not make a material alteration after notarization. Ask whether the recipient requires a newly executed corrected affidavit, a supplemental affidavit, or another formal correction.
