Quick answer

An affidavit is a written statement of facts made voluntarily under oath or affirmation. For an ordinary paper affidavit in the Philippines, the affiant generally must:

Use a document that clearly identifies the affiant and states facts truthfully, preferably in numbered paragraphs.
Bring the complete, unsigned affidavit and any attachments to a duly commissioned notary public.
Personally appear before the notary.
Present competent evidence of identity unless personally known to the notary.
Sign the affidavit in the notary’s presence and take an oath or affirmation.
Ensure that the notary completes the jurat, signs it, affixes the official seal, and enters the act in the notarial register.

A notary should not notarize an affidavit merely because someone else brought it to the office, because the affiant appeared by video call outside the authorized electronic-notarization system, or because the affidavit was already signed and the affiant is absent.

These are the general rules. A court, government agency, bank, school, employer, foreign authority, or particular transaction may require a prescribed form, additional witnesses, specific attachments, recent issuance, or a separate authentication or apostille.

What an affidavit should contain

There is no single form for every Philippine affidavit. Its contents depend on its purpose—for example, an affidavit of loss, complaint-affidavit, affidavit of discrepancy, affidavit of undertaking, or judicial affidavit.

A properly prepared ordinary affidavit usually contains:

A title describing its purpose.
A venue or heading identifying the Philippines and the relevant city, municipality, or province.
The affiant’s complete name and identifying details, such as age or a statement that the person is of legal age, citizenship, civil status when relevant, and address.
A statement that the affiant is executing the document voluntarily and under oath.
Clear, consecutively numbered statements of fact.
Facts based on the affiant’s personal knowledge, with dates, places, names, amounts, and events stated accurately.
Identification of supporting documents, with attachments properly marked when required.
A statement explaining the affidavit’s purpose.
The affiant’s signature over the printed name.
A proper jurat completed by the notary or other officer authorized to administer oaths.

Avoid copying a generic form without checking whether it fits the intended filing. An affidavit of loss, for example, should normally identify the lost item or document, explain how and when it was lost, describe the efforts made to find it, and state the purpose for which the affidavit is being executed. An affidavit cannot legally transfer ownership merely because it is notarized.

Jurat versus acknowledgment

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

In a jurat, the affiant:

Personally appears before the notary;
Is identified through competent evidence of identity or is personally known to the notary;
Signs the affidavit in the notary’s presence; and
Swears or affirms that the statements in it are true.

An acknowledgment is different. It is commonly used for deeds, contracts, and authorizations. The signer personally appears and confirms that the signature is genuine and that the document is the signer’s free and voluntary act. The document may have been signed beforehand, although personal appearance and proper identification remain necessary.

Using the wrong certificate can create evidentiary or filing problems. The receiving court or agency may reject an affidavit that has only an acknowledgment when a sworn statement with a jurat is required.

Personal appearance is essential

For traditional notarization of a paper affidavit, the affiant must personally appear before the notary at the time of notarization. The Supreme Court has repeatedly treated notarization without the signer’s presence as a serious violation of the notarial rules.

Accordingly:

A relative, liaison, employee, or messenger cannot appear in the affiant’s place.
Leaving a signed affidavit at a notary’s office for later notarization is improper.
Sending a photograph or scanned copy of an ID does not replace personal appearance.
An ordinary Zoom, Messenger, Viber, or similar video call does not by itself satisfy the rules for notarizing a wet-ink paper affidavit.
A notary should not certify that an affiant appeared on a date when no appearance occurred.

The personal-appearance requirement allows the notary to verify identity, observe voluntariness, administer the oath, and determine whether the signer understands the document.

What identification is acceptable?

Under the amended definition of “competent evidence of identity” in the 2004 Rules on Notarial Practice, the usual requirement is at least one current identification document issued by an official agency that bears the person’s photograph and signature.

Examples recognized by the rules include a passport, driver’s license, PRC ID, NBI clearance, police clearance, GSIS e-card, SSS card, PhilHealth card, senior-citizen card, OWWA or OFW identification, seaman’s book, alien certificate of registration, and qualifying government-office or government-agency certifications.

The controlling test is not simply whether a card is commonly called a “valid ID.” It must be current, issued by an official agency, and bear both the holder’s photograph and signature. A school or private-company ID does not satisfy this documentary-identification route merely because it has a photograph and signature.

Bring the original ID, not only a photocopy or phone image. The name and signature should be consistent with the affidavit. If they are not, bring supporting records explaining the discrepancy.

When the affiant has no qualifying ID

The rules also allow identification through credible witnesses, subject to strict conditions:

One credible witness may identify the affiant if that witness is personally known to the notary, personally knows the affiant, and is not a party or otherwise privy to the document or transaction; or
Two credible witnesses may identify the affiant if neither is privy to the document or transaction, each personally knows the affiant, and each presents the required documentary identification to the notary.

A companion who will benefit from the affidavit or transaction may be disqualified from serving as a credible identifying witness. Ask the notary in advance what the witness must bring.

A community tax certificate or cedula should not be relied upon as the sole proof of identity under the current competent-evidence rule.

What the notary must check

A commissioned notary is not merely a signature-and-seal service. Before completing the act, the notary should verify the affiant’s identity, personal appearance, willingness, and understanding.

The notary must refuse or stop the notarization when, among other grounds:

The affiant is absent or cannot be properly identified.
The document is blank or incomplete.
The notarial certificate is incomplete.
The notary knows or has good reason to believe that the transaction is unlawful.
The affiant appears unable to understand the nature or consequences of the act.
The affiant is being forced or does not appear to act voluntarily.
The notary is disqualified because of a prohibited interest or relationship.
The requested act is outside the notary’s authority or territorial jurisdiction.

The completed paper affidavit should bear a proper jurat and the notary’s official signature and seal. The notarial details ordinarily include the document, page, book, and series numbers. The act must also be recorded in the notarial register.

Under the Supreme Court’s 2025 amendments, traditional notaries have additional electronic record-retention and reporting duties. These administrative duties belong primarily to the notary, but an affiant should keep an exact copy of the fully notarized document.

Does an affidavit need witnesses?

An ordinary affidavit generally does not require subscribing witnesses in addition to the affiant and notary. Witnesses may nevertheless be required when:

A specific law, court rule, agency form, or transaction requires them;
The affidavit is a joint affidavit executed by several affiants;
A witness is needed to identify an affiant who lacks acceptable identification;
The signer uses a mark or has a disability requiring special accommodations; or
The underlying document—not merely the affidavit—has separate witness requirements.

Do not add “disinterested witnesses” simply because a template contains signature lines. Determine whether they are legally or administratively required and whether they are qualified.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC supplement traditional notarization. They cover electronic documents and permit:

In-Person Electronic Notarization, where the principal physically appears before a commissioned Electronic Notary Public; and
Remote Electronic Notarization, where the principal appears synchronously through an accredited Electronic Notarization Facility.

Remote notarization is not accomplished by emailing a scanned signature to an ordinary notary. It must involve:

A separately commissioned Electronic Notary Public;
A Supreme Court-accredited electronic-notarization facility;
Identity verification through that facility;
A live, synchronous session—not a prerecorded video;
Confirmation that the act is voluntary and that the document being notarized is the same document presented by the principal;
The required electronic signature, electronic notarial certificate, and electronic seal; and
Compliance with the Rules’ location, recordkeeping, and security requirements.

Except for limited extraterritorial notarization under the Rules, participants in remote electronic notarization must be in the Philippines. A principal abroad may use the process only under the prescribed conditions, including being within the premises of a Philippine embassy, consular office, or office of a Philippine honorary consul while the Electronic Notary Public remains in the Philippines.

The electronic rules do not govern notarial wills, depositions, or paper instruments bearing wet signatures or marks. Those remain subject to the applicable traditional rules. Availability also depends on a properly commissioned Electronic Notary Public and an accredited facility; confirm both through current Supreme Court channels before paying or sending sensitive documents.

Affidavits executed abroad

A Filipino abroad should first ask the intended Philippine recipient what form of authentication it accepts. Common routes include:

Execution before a Philippine embassy or consulate authorized to perform the relevant notarial or consular service; or
Execution before a competent local notary, followed—when required—by an apostille from the foreign country’s competent authority if that country is a party to the Apostille Convention.

Documents from countries outside the apostille system may require consular authentication or another process specified by the receiving authority. Translation may also be required.

An apostille authenticates the origin of a public document, such as the signature and official capacity of the person who executed or certified it. It does not establish that every factual statement in the affidavit is true. Consult the Department of Foreign Affairs and the Philippine embassy or consulate serving the place of execution for current appointment and document requirements.

Special rules for judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it generally must be in the language known to the witness and contain consecutively numbered questions and answers, specified witness and lawyer information, identification of evidence, the witness’s signature, and a jurat. The examining lawyer must also execute the required sworn attestation.

Deadlines depend on the proceeding. As a general civil-case rule, judicial affidavits and attached exhibits are filed and served not later than five days before pre-trial, preliminary conference, or the scheduled hearing involving the witnesses. Criminal cases have additional provisions, including a five-day-before-pre-trial deadline for the prosecution’s affidavits. Special courts, procedural rules, or court orders may control.

Failure to submit a required judicial affidavit on time can result in waiver. A court may allow late submission only once under the conditions stated in the Rule, including a valid reason, absence of undue prejudice, and payment of the prescribed fine. Because the consequences can affect the presentation of evidence, have counsel confirm the controlling deadline.

Practical checklist

Before visiting the notary:

Confirm the exact form and recency requirement with the receiving office.
Review every statement for accuracy.
Remove blank spaces or mark inapplicable fields appropriately.
Check that names, dates, addresses, and document numbers match the supporting records.
Prepare readable copies of all referenced attachments.
Bring the original current government-issued photo-and-signature ID.
Bring all affiants; each must personally appear.
Do not pre-sign a paper affidavit requiring a jurat unless the notary specifically instructs you to sign during the appearance.
Ask whether the notary is currently commissioned for the place and type of notarization.
After notarization, inspect the jurat, signature, seal, date, place, and notarial register details.
Keep the original safely and retain a complete scanned copy, including attachments and the notarial page.
Obtain proof of submission or receipt from the court, agency, or organization accepting the affidavit.

Evidence to preserve

Keep records that can prove both the underlying facts and proper execution of the affidavit:

The final notarized affidavit and every attachment;
Earlier drafts showing corrections, if a dispute is foreseeable;
The ID presented, stored securely and disclosed only when necessary;
Receipts and appointment confirmations;
Emails or written instructions from the receiving office;
Filing receipts, docket numbers, tracking records, and acknowledged copies;
Photographs, messages, contracts, official records, or reports supporting the sworn facts; and
Contact details of persons with firsthand knowledge.

Preserve original electronic files and message histories rather than relying only on screenshots. Do not alter records after learning of a dispute or investigation.

Common mistakes

Frequent problems include:

Signing outside the notary’s presence when a jurat is required.
Using an acknowledgment instead of a jurat.
Presenting an expired ID or a private-company ID as the only identification.
Leaving important blanks in the affidavit or jurat.
Giving dates, names, or document numbers that conflict with official records.
Attaching evidence that is unreadable, incomplete, or not identified in the affidavit.
Assuming notarization proves that every statement is true.
Treating an affidavit as a substitute for a deed, contract, court order, or official correction procedure.
Using an ordinary video call as “remote notarization.”
Backdating the affidavit or asking a notary to certify an appearance that did not occur.
Missing the separate filing deadline because the document was notarized on time.
Assuming an affidavit remains acceptable forever.

There is no universal expiration date for affidavits. However, the receiving authority may demand a recently executed document, and an affidavit may become inaccurate when circumstances change.

Legal effect and limits of notarization

Proper notarization is a safeguard against fraud and can give a document important evidentiary status. Under the Rules on Evidence, documents acknowledged before a notary—except last wills and testaments—are among the classes of public documents. Defective notarization may reduce a document to the status of a private document requiring proof of due execution and authenticity.

Notarization does not:

Make a false statement true;
Cure an illegal transaction;
Prove facts outside the notary’s personal certification;
Automatically transfer property or establish ownership;
Replace substantive requirements imposed by law; or
Guarantee that a court or agency will accept the document.

Whether lack of notarization invalidates an underlying transaction depends on the applicable law. Article 1358 of the Civil Code requires specified acts and contracts to appear in a public document, but Supreme Court decisions explain that noncompliance does not invariably invalidate the agreement. Other transactions may have a form required for validity, enforceability, registration, or effect against third persons. Obtain document-specific advice for property, succession, corporate, loan, family, and high-value transactions.

False affidavits and improper notarization

Knowingly making a material false statement under oath for a legal purpose can constitute perjury if all statutory elements are present. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, perjury is punishable by prisión mayor in its minimum period. A public officer or employee may face the maximum period and additional consequences specified by the law, including a fine of up to ₱1,000,000 and perpetual absolute disqualification from government office.

Other offenses—such as falsification, use of falsified documents, fraud, or obstruction-related offenses—may apply depending on what was done and how the affidavit was used. Liability is never automatic from a mere factual error; intent, materiality, purpose, and the other elements of the alleged offense must be proved.

A lawyer-notary who violates the notarial rules may face revocation or suspension of the notarial commission, disqualification from future commissioning, and professional discipline. A questionable notarization may also undermine the document in court.

When legal help is urgent

Consult a Philippine lawyer promptly if:

Someone signed or notarized a document using your name without authority.
A deed, waiver, authority to sell, loan, settlement, or property affidavit was notarized without your appearance.
You are being pressured to sign an inaccurate or incomplete affidavit.
Police, prosecutors, the NBI, the Ombudsman, or another investigating body requires your sworn statement.
Your affidavit may expose you or another person to criminal, civil, tax, immigration, employment, or administrative liability.
A court deadline is approaching.
The affidavit concerns land, inheritance, marital status, custody, substantial money, corporate authority, or a foreign proceeding.
An agency rejected the affidavit and the deadline to correct it is running.
You discover a material mistake after filing.

Do not destroy or alter the disputed document. Secure copies, record how you obtained them, preserve communications and receipts, and note the names of the notary and witnesses.

Frequently asked questions

Can I notarize an affidavit that I already signed?

For a jurat, the affidavit must be signed in the notary’s presence. If it was signed beforehand, the notary may require a fresh unsigned copy or require you to sign again properly. Do not assume that acknowledging an old signature is enough.

Are two valid IDs always required?

The Supreme Court’s competent-evidence rule generally calls for at least one current official-agency ID bearing both photograph and signature. A notary or receiving institution may reasonably request additional identification or supporting records, particularly when names or details do not match.

Can a barangay official notarize an affidavit?

Not merely by being a barangay official. A person must have legal authority to administer the required oath or perform the notarial act. For ordinary notarization, use a duly commissioned notary public unless a specific law authorizes another officer to administer that particular oath.

Can any lawyer notarize a document?

No. Being a lawyer does not automatically authorize notarial practice. The lawyer must hold a current notarial commission and act within the authority and territorial jurisdiction granted by the commissioning court. Electronic notarization requires a separate electronic notarial commission.

Is a notarized affidavit conclusive proof?

No. It may carry evidentiary weight, but its statements can be challenged through admissible evidence. The notary generally certifies the appearance, identity, oath or acknowledgment, and execution—not independent knowledge that every factual allegation is correct.

How much does notarization cost?

The notarial rules permit reasonable fees, and the applicable schedule may vary by locality, document, complexity, copies, and professional services involved. Ask the notary for the charge before proceeding and request a receipt. Drafting or legal review is separate from the notarial act and may cost more.

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

Do not make an unnoted alteration after notarization. For a material error, the safer course is usually to execute a corrected or supplemental affidavit, identify the earlier document, and follow the receiving authority’s instructions.

Where can I verify the governing rules?

The principal official references are the Supreme Court’s Amended 2004 Rules on Notarial Practice, Rules on Electronic Notarization, and electronic-notarization FAQs.
