Quick answer

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

Use the form and wording required by the receiving court, agency, school, bank, employer, or other institution.
State facts truthfully, clearly, and—unless the applicable rule allows otherwise—from personal knowledge.
Bring the complete, unsigned affidavit to a duly commissioned notary public or another officer legally authorized to administer oaths.
Personally appear before that officer.
Present competent evidence of identity unless personally known to the notary under the governing rules.
Sign the affidavit in the officer’s presence and take the oath or affirmation.
Ensure that the jurat and the notary’s commission details are complete.

Notarization does not prove that every statement in an affidavit is true, cure false information, or make an otherwise illegal or defective transaction valid. Requirements also vary by purpose: a court affidavit, affidavit of loss, complaint-affidavit, affidavit of support, or document for overseas use may require a prescribed form, attachments, witnesses, authorization, an apostille, or compliance with a specific filing deadline.

What makes a document an affidavit?

A document is ordinarily an affidavit when it contains:

The affiant’s name and relevant personal details;
A clear statement that the affiant is competent to testify to the matters stated;
Numbered or logically arranged factual statements;
Any required reference to supporting documents;
The affiant’s signature;
A statement that the contents are sworn or affirmed as true; and
A properly completed jurat.

An unsworn narrative signed privately is generally not an affidavit merely because it is labeled “Affidavit.” The oath or solemn affirmation must be administered by a person authorized by law.

There is no single universal affidavit template for every Philippine transaction. The receiving authority’s current form and instructions control. For example, judicial affidavits, verifications, certifications against forum shopping, immigration affidavits, affidavits of support, and administrative complaint-affidavits have different substantive and procedural requirements.

Jurat versus acknowledgment

These notarial acts are not interchangeable.

Jurat

A jurat is normally used for an affidavit. The affiant must personally appear, sign the document in the notary’s presence, and swear or affirm that its contents are true.

Typical language states that the document was “subscribed and sworn to” before the notary. The precise certificate should be completed by the notary, not copied blindly from an unrelated form.

Acknowledgment

An acknowledgment is commonly used for deeds, contracts, powers of attorney, and similar instruments. The signer personally appears and declares that the signature and execution of the document are voluntary. The instrument may have been signed before the appearance, provided the signer properly acknowledges it in accordance with the rules.

Using a jurat where an acknowledgment is legally required—or the reverse—can create evidentiary, registration, or acceptance problems. The Supreme Court has expressly distinguished jurats for affidavits and pleadings from acknowledgments for written deeds and acts in Ladrera v. Osorio.

Personal appearance is the general rule

Under the 2004 Rules on Notarial Practice, a paper document must not be notarized when the signatory is not personally present before the notary at the time of notarization.

Accordingly:

Do not send a signed affidavit through a messenger and ask the notary to complete the jurat.
A relative, employee, liaison, or lawyer cannot personally appear in place of the affiant.
A phone call or ordinary video call is not a substitute for the procedure required for paper notarization.
Every affiant whose signature is being notarized must comply with the applicable appearance and identification requirements.
Never agree to backdating or to a certificate falsely stating that you appeared on a date when you did not.

For a jurat, it is safest to leave the affidavit unsigned until the notary instructs you to sign.

Identification requirements

The notary must personally know the signatory or identify the signatory through competent evidence of identity. Following the Supreme Court’s 2008 amendment, this ordinarily means at least one current identification document issued by an official agency bearing the holder’s photograph and signature.

Examples in the rule include a passport, driver’s license, PRC ID, SSS card, GSIS e-card, senior-citizen card, government-office ID, seaman’s book, alien registration certificate, and other qualifying government-issued identification. The complete governing definition appears in the Supreme Court’s February 19, 2008 resolution.

A particular card should not be assumed sufficient merely because it is commonly called a “valid ID.” It must be current and satisfy the rule’s identifying features. Bring the original, not only a photograph or photocopy. The notary may need to record the ID details and may request a copy for the notarial record.

Where the rules permit identification through credible witnesses, strict conditions apply. Depending on the situation, this may require:

One credible witness who is personally known to the notary and personally knows the affiant; or
Two credible witnesses who personally know the affiant, satisfy the rule’s identification requirements, and take the required oath or affirmation.

Credible-witness identification is not a casual workaround for an expired or missing ID. Confirm the arrangement with the notary before the appointment.

What to bring to the notary

Bring:

The complete affidavit, with no unexplained blanks;
Your original current government-issued photo-and-signature ID;
Any additional ID requested by the notary or receiving authority;
Original supporting records relevant to the affidavit;
Copies of exhibits that will be attached;
Proof of authority if signing for an organization or another person, such as a board resolution, secretary’s certificate, or special power of attorney;
The receiving authority’s current checklist or prescribed form; and
A working email address or other information reasonably needed for delivery of the electronic copy required under the amended reporting rules.

If the document has several pages, check that names, dates, page numbers, exhibit labels, and signature spaces are consistent throughout. Do not insert, remove, or replace pages after notarization.

What the notary must check

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

The signatory is absent;
Identity has not been properly established;
The document is blank or incomplete;
The notarial certificate is missing or inappropriate;
The transaction appears unlawful or immoral;
The signer apparently does not understand the consequences;
The signer does not appear to be acting freely;
The notary is disqualified because of a prohibited interest or relationship; or
The requested act is outside the notary’s authority, territorial jurisdiction, or valid commission.

Notarial practice is not simply the sale of a signature and seal. The notary must make a contemporaneous entry in the notarial register and complete the required certificate and commission information.

The Supreme Court’s 2025 amendments also introduced digital-copy transmission and reporting safeguards for paper notarizations. The notary may need to scan and transmit the notarized document in the prescribed manner. The notary may not impose an additional fee merely for digitizing, transmitting, or processing those copies. See the Supreme Court’s official summary of the amendments and the amended rules.

Electronic and remote notarization

The Supreme Court has adopted separate Rules on Electronic Notarization, A.M. No. 24-10-14-SC. These rules cover electronic documents through in-person electronic notarization and remote electronic notarization.

Remote electronic notarization is not the same as emailing a scanned signature to an ordinary notary or joining an informal video call. It must be performed by a properly commissioned Electronic Notary Public, using the authorized electronic-notarization framework and its identity, appearance, signing, recording, and document-integrity safeguards.

As of the source check date, the Supreme Court’s portal states that applications for commissioning electronic notaries opened on August 10, 2026. Before relying on electronic notarization, confirm that:

The electronic-notary service is operational for the proposed transaction;
The chosen lawyer holds a valid electronic notarial commission;
The document is eligible for that method;
The affiant and document satisfy all platform and identity requirements; and
The receiving institution accepts the resulting electronic document.

Current notices and official FAQs are available through the Supreme Court’s eNotarization portal.

Notarization does not prove the truth of the affidavit

Notarization primarily establishes the formal notarial act, including appearance, identification, oath or acknowledgment, execution, and date. It does not make the notary a witness to the underlying events described in the affidavit.

The Supreme Court has clarified that notarized documents are generally prima facie evidence of due execution and authenticity—not automatically of the truth of all their contents. An affidavit may still be challenged, contradicted, excluded, or given little weight based on the evidence and applicable procedural rules. See G.R. No. 253527, October 21, 2024.

Notarization also does not:

Transfer ownership when substantive legal requirements are absent;
Cure incapacity, fraud, forgery, illegality, or lack of authority;
Replace registration, recording, tax, or agency approvals;
Guarantee that an affidavit will be accepted; or
Excuse a late or incorrectly filed document.

Special rules for court and agency filings

Do not assume that notarization alone completes a filing.

For court pleadings, the Rules of Court determine whether a verification, affidavit, or sworn certification is required. Pleadings generally need not be verified unless a law or rule specifically requires it. When verification is required, defective wording or execution can have procedural consequences. A certification against forum shopping has separate requirements and is generally treated more strictly than an ordinary verification. The current civil procedure rules are in A.M. No. 19-10-20-SC.

A judicial affidavit is governed by the Judicial Affidavit Rule, including requirements concerning the questions and answers, attachments, interpreter or translator when applicable, the witness’s oath, and the examining lawyer’s sworn attestation.

Prosecutors’ offices, the police, the NBI, the Ombudsman, administrative agencies, schools, insurers, banks, and local governments may each prescribe their own forms, number of copies, documentary attachments, submission channels, and deadlines. Obtain the current checklist from the office that will actually receive the affidavit.

Is there a deadline or expiration date?

There is no universal expiration period for every affidavit. Its usefulness depends on:

The law or procedure governing the transaction;
A filing or appeal deadline;
The receiving authority’s recency requirement;
Whether the facts remain accurate;
Whether an attached ID, authority, or supporting document has expired; and
Whether circumstances have materially changed since execution.

An affidavit can become unacceptable even without a formal “expiry date” if the receiving office requires a recently executed document or if its factual statements are no longer accurate. Never alter the date or reuse an old affidavit to describe changed circumstances. Execute a new one when necessary.

Affidavits executed abroad

First ask the Philippine receiving authority what form of authentication it requires.

Common lawful routes include:

Personal execution before a Philippine embassy or consulate authorized to perform the relevant consular notarial act; or
Notarization under the law of the foreign country, followed—where applicable—by an apostille issued by the competent authority of that country.

An apostille generally authenticates the origin of the public document, including the official signature or seal. It does not certify the truth of the affidavit’s factual statements. If the country of origin or destination is not covered by the Apostille Convention—or a special exception applies—authentication or legalization requirements may differ.

Consular appointment systems, fees, copies, identification requirements, and processing times vary by post. Check the website of the Philippine embassy or consulate serving the place where the affidavit will be executed. Official DFA guidance confirms that personal appearance and proof of identity remain central to consular notarization; see this Philippine Embassy authentication and notarial guidance.

Practical step-by-step checklist

Ask the receiving office for its latest form and checklist. Confirm the required wording, attachments, number of originals, deadline, and whether paper or electronic notarization is accepted.
Draft facts, not arguments or guesses. Identify dates, places, people, and events precisely. Distinguish what you personally observed from information obtained elsewhere.
Check every statement. Compare names, civil status, addresses, identification numbers, property descriptions, account references, and dates with the source documents.
Prepare exhibits. Mark and arrange attachments consistently with the references in the affidavit.
Do not leave material blanks. Strike out unused spaces when appropriate. Never sign an incomplete affidavit.
Choose a properly commissioned notary. Confirm that the commission is current and covers the place where the paper notarization will occur.
Appear personally with original ID. Sign and take the oath or affirmation as instructed.
Review the completed jurat. Check the date and place, ID reference, notarial register details, commission particulars, seal, and signature.
Obtain and protect your copy. Keep the complete notarized document, including every annex.
File it on time. Notarization does not stop or extend a court, agency, contractual, or statutory deadline.

Evidence to preserve

Keep:

The exact final affidavit and all signed pages;
Every attachment in the form submitted;
Clear copies of the identification presented;
The official receipt or acknowledgment from the notary, if issued;
The electronic copy transmitted by the notary;
Filing receipts, docket numbers, stamped receiving copies, courier records, and email confirmations;
The form and checklist supplied by the receiving office;
Drafts and source documents showing how names, dates, amounts, and descriptions were verified; and
Messages or records relevant to voluntariness, authority, or the circumstances described.

If forgery or improper notarization is suspected, preserve the original document. Avoid writing on it, removing staples, replacing pages, or surrendering the only copy without obtaining a documented receipt.

Common mistakes

Signing a jurat-based affidavit before appearing before the notary;
Asking for notarization through a messenger;
Using an expired ID or a card without the required photograph and signature;
Copying a jurat from an unrelated document;
Leaving dates, names, amounts, or attachments blank;
Using inconsistent names or dates across the affidavit and exhibits;
Presenting conclusions, hearsay, or speculation as personal knowledge;
Failing to disclose that the signer acts for a corporation, estate, minor, or another person;
Assuming notarization makes the contents true or the transaction valid;
Confusing notarization with apostille, authentication, registration, or filing;
Altering the document after it was notarized;
Backdating the affidavit; and
Missing the receiving office’s deadline while focusing only on notarization.

False affidavits and improper notarization

Knowingly making an untruthful statement under oath on a material matter can expose an affiant to prosecution for perjury when the legal elements are present. Article 183 of the Revised Penal Code was amended by Republic Act No. 11594. Other offenses—such as falsification, use of falsified documents, fraud, or obstruction-related offenses—may also become relevant depending on the facts.

Notaries may face revocation of their commission, disqualification from notarial practice, professional discipline, and possible civil or criminal consequences. The precise liability and penalty depend on the act proved and the law in force when it occurred.

When legal help is urgent

Consult a Philippine lawyer promptly if:

A court, prosecutor, police unit, immigration office, or regulator has given you a deadline;
The affidavit may expose you or another person to criminal, tax, immigration, employment, or regulatory liability;
You are being pressured to sign something inaccurate or incomplete;
The document concerns land, inheritance, custody, substantial money, corporate authority, or waiver of rights;
An elderly, ill, detained, or otherwise vulnerable signer may lack capacity or be acting under pressure;
A signature, seal, page, date, or notarial entry appears forged or altered;
A notarized document was supposedly signed without the person’s appearance;
You need to retract, correct, or contradict an earlier sworn statement; or
A foreign authority has rejected the document or requires legalization beyond ordinary notarization.

Do not “correct” a sworn affidavit by erasure, substitution of pages, or handwritten alteration after notarization. Ask whether a new or supplemental affidavit is required.

Frequently asked questions

Can I notarize a photocopy of an affidavit?

The original affidavit normally carries the affiant’s original signature and jurat. A notary may perform a different authorized act involving a copy when legally appropriate, but notarizing or certifying a copy is not the same as executing the original affidavit under oath. Ask the receiving authority what it requires.

Can two or more people sign one affidavit?

Yes, if the form and purpose allow joint affiants. Each affiant must satisfy the applicable appearance, identification, oath, and signing requirements. Each person is responsible for the statements sworn to.

Must an affidavit be written in English?

Not necessarily. The affiant must understand the document and the oath. The receiving authority may prescribe a language or require a translation. Judicial affidavits involving a language not understood by the witness have specific interpreter or translator requirements.

Can a minor execute an affidavit?

Capacity, comprehension, voluntariness, and the specific legal purpose must be evaluated. Some transactions require a parent, guardian, court authority, or a prescribed consent form. Seek legal advice instead of assuming that notarization alone resolves capacity.

Can a notary refuse to notarize my affidavit?

Yes. A notary should refuse when legal requirements are not met, identity or voluntariness is doubtful, the document is incomplete, the requested act is improper, or the notary is disqualified.

Does a notarized affidavit automatically win a case?

No. It remains subject to admissibility rules, objections, cross-examination requirements where applicable, contrary evidence, and the court’s assessment of credibility and weight.

How much should notarization cost?

Fees may depend on the authorized schedule, nature of the act, number of signatories or documents, and any separately agreed lawful travel expense. Ask for the amount before proceeding and request a receipt. No additional fee may be imposed merely for the digitization, transmission, or processing required by the 2025 amendments.

Can an affidavit be notarized online?

Only through a legally authorized electronic-notarization process performed by a duly commissioned Electronic Notary Public, for an eligible electronic document and in compliance with the Supreme Court’s rules. An ordinary video call, emailed scan, or pasted electronic signature is not enough.

Is an apostille the same as notarization?

No. Notarization concerns the execution, identity, acknowledgment, or oath involved in the document. An apostille authenticates the origin of a public document for use under the Apostille Convention. A document may require both stages.
