Quick answer

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

State facts truthfully and, as far as possible, from personal knowledge.
Use the form and include the information required by the court, agency, bank, school, employer, or other receiving office.
Personally appear before a duly commissioned notary public or another officer legally authorized to administer the particular oath.
Establish identity through personal knowledge or competent evidence of identity.
Sign the complete affidavit in the notary’s presence and take the oath or affirmation.
Ensure that the notary completes a jurat, signs it, affixes the official seal, and records the act in the notarial register.

An ordinary acknowledgment is not a substitute for a jurat when the document must be sworn. A notary should not notarize a blank or incomplete affidavit, accept appearance through a representative, rely only on a cedula, backdate the document, or complete a paper notarization through an informal video call.

Electronic affidavits may now be notarized in person or remotely, but only under the Supreme Court’s regulated electronic-notarization system, using a commissioned Electronic Notary Public and an accredited Electronic Notarization Facility. The rules for paper and electronic documents are different.

What makes a document an affidavit?

The essential feature is the oath or solemn affirmation. The affiant declares before an authorized officer that the material statements in the document are true.

A properly prepared affidavit ordinarily contains:

An appropriate title, such as “Affidavit of Loss,” “Affidavit of Desistance,” or “Joint Affidavit.”
The affiant’s full legal name and identifying details required for the transaction.
Clear, consecutively numbered statements of fact.
An explanation of how the affiant knows those facts.
Identification of attached documents, photographs, messages, receipts, or other evidence.
A statement that the affidavit is being executed for its stated legal purpose.
The affiant’s signature over the printed name.
A jurat completed by the notary or other authorized officer.

There is no single universal affidavit form. An affidavit for a passport, insurance claim, preliminary investigation, court case, land transaction, estate, immigration matter, or administrative proceeding may have additional statutory or agency requirements. The receiving office’s current form and instructions control.

Jurat versus acknowledgment

The distinction matters.

Jurat

A jurat is normally used for an affidavit. The affiant:

Personally appears before the notary;
Presents the complete document;
Is personally known to the notary or properly identified;
Signs in the notary’s presence; and
Takes an oath or affirmation concerning the document.

The jurat commonly begins with words such as “Subscribed and sworn to before me,” but wording alone does not cure a failure to administer the oath or require personal appearance.

Acknowledgment

An acknowledgment is generally used when a person confirms that a signature on a complete instrument was voluntarily affixed and that the document is the person’s free and voluntary act and deed. It is common in deeds, contracts, powers of attorney, and similar instruments.

If a government form specifically requires an affidavit, sworn declaration, verification, or jurat, using only an acknowledgment may be a material defect. The governing definitions appear in the Supreme Court’s 2004 Rules on Notarial Practice.

Requirements for a paper affidavit

1. The affidavit must be complete

A notary public may not notarize a blank or incomplete document. Before the appointment:

Fill in all material names, dates, addresses, amounts, descriptions, and other required information.
Attach every exhibit referred to in the affidavit.
Check that pages are complete and in the correct order.
Remove unexplained blank spaces.
Make sure the affiant understands the entire document.

Do not ask a notary to notarize only the signature page while material pages or attachments are missing.

2. The correct person must appear

The affiant must personally appear before the notary at the time of a traditional paper notarization. A relative, employee, messenger, attorney-in-fact, or other representative cannot take the affiant’s oath or confirm facts that only the affiant knows.

The Supreme Court has disciplined a notary who accepted a video call and representatives in place of the affiants’ personal appearance. Under the traditional rules, informal telephone or video confirmation is not substantial compliance. See Lacaba v. Baterina, A.C. No. 9269.

3. Identity must be properly established

If the affiant is not genuinely personally known to the notary, competent evidence of identity is required. The usual method is at least one current identification document issued by an official agency bearing the affiant’s photograph and signature, such as a valid passport, driver’s license, PRC ID, or another qualifying government-issued ID.

A community tax certificate or cedula alone is not competent evidence of identity because it does not bear the required photograph and signature.

If the affiant has no qualifying ID, the rules provide a limited credible-witness route:

One credible witness who is not involved in the document or transaction, is personally known to the notary, and personally knows the affiant; or
Two credible witnesses who are not involved in the document or transaction, each personally knows the affiant, and each presents proper documentary identification.

A receiving office may separately require a photocopy or electronic image of the affiant’s ID even when the notary personally knows the affiant.

4. The affiant must sign and take the oath

For a jurat, the affidavit must be signed in the notary’s presence. If it was signed earlier, disclose that fact. The notary may require the affiant to sign again in the notary’s presence.

The notary should administer an oath or solemn affirmation and must be satisfied that the affiant:

Understands the general nature and consequences of the document;
Is acting voluntarily;
Is not being coerced or improperly influenced; and
Is capable of making a meaningful oath or affirmation.

The notary must refuse if the transaction appears unlawful or immoral, the signer’s conduct creates reasonable doubt about their understanding, or the signer does not appear to be acting freely.

5. The notarial certificate must be complete

Before leaving, inspect the jurat. It should show, as applicable:

The place and date of notarization;
The affiant’s personal appearance and identification;
The notary’s handwritten official signature;
A clear official seal;
The notary’s commission number, commissioned city or province, commission expiry, and office address;
Roll of Attorneys, IBP, and professional tax receipt details; and
The document number, page number, book number, and series in the notarial register.

A seal or signature pasted onto a document without an actual notarial act is not valid notarization.

Where a paper affidavit may be notarized

A traditional notary public may act only within the territorial jurisdiction of the commissioning court and ordinarily at the notary’s registered place of work or business.

The rules allow certain acts elsewhere within that same territorial jurisdiction, including specified public or function areas, hospitals or medical institutions where a party is confined, and places where a party is detained. A notary commissioned for one territory cannot simply perform traditional notarizations anywhere in the country.

Check that the notary’s commission is current and covers the place where the notarization occurs. Being a lawyer does not automatically authorize a person to notarize; the lawyer must hold a valid notarial commission.

The notary is also disqualified if the notary is a party to the document, has a prohibited interest in it, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by blood or marriage within the fourth civil degree.

Who else may administer an oath?

Philippine law gives oath-administering authority to specified public officers. Other officers may also administer oaths when their legally defined duties require sworn statements. PAO lawyers have authority in connection with their official duties.

This does not mean that any government employee or barangay official can notarize private affidavits. Most public officers’ authority is tied to official business or a specific statutory function. For example, a punong barangay’s authority under Republic Act No. 10755 concerns oaths of office, not a general power to notarize private documents.

The relevant provisions include Executive Order No. 292, Republic Act No. 9406, and Republic Act No. 10755. Confirm that the receiving office recognizes the officer and the officer is acting within the legally authorized function.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement traditional paper notarization. They apply to electronic documents and recognize:

In-Person Electronic Notarization, where the principal and witnesses physically appear before an Electronic Notary Public; and
Remote Electronic Notarization, where appearance occurs through synchronous videoconferencing using an accredited Electronic Notarization Facility.

An ordinary notary, commercial video-conferencing account, scanned signature, or emailed PDF does not by itself satisfy these rules. According to the Supreme Court’s eNotary Services guidance, an electronic document in PDF or PDF/A format should be handled by a commissioned Electronic Notary Public through an accredited facility.

Identity verification, voluntariness checks, document confirmation, electronic signatures and seals, and the notarial record must be completed through the regulated facility. Pre-recorded signing videos are not a substitute for synchronous appearance.

For a principal outside the Philippines, electronic notarization is permitted only under the conditions stated in the rules, including that the Electronic Notary Public is physically in the Philippines and that the overseas principal is within the premises of a Philippine embassy, consular office, or Philippine honorary consul’s office. Confirm the current process through the Supreme Court’s eNotarization FAQ.

The 2020 remote-paper rules were a community-quarantine stopgap. They should not be treated as continuing permission to have an ordinary paper affidavit notarized through a casual video call. The permanent electronic rules now govern electronic documents, while ordinary paper affidavits remain subject to the traditional personal-appearance requirements.

Special signing situations

Thumbmark or another mark

A person who cannot sign but can make a thumbmark or other mark may do so only under the safeguards in the notarial rules. The mark must be made in the presence of the notary and two disinterested and unaffected witnesses. The witnesses must sign, and the notary must place the prescribed notation.

Person physically unable to sign or make a mark

A notary may sign for a person who is physically unable to sign or make a mark only if:

The person directs the notary to sign on their behalf;
Two disinterested and unaffected witnesses are present;
Both witnesses sign;
The notary places the prescribed notation; and
The notary completes the appropriate acknowledgment or jurat.

These procedures should be arranged with the notary beforehand. They are not shortcuts for an absent affiant.

Language, literacy, or capacity concerns

Use a language the affiant understands. If the affidavit is for court, agency, immigration, property, medical, or financial use, obtain advice about translation and interpreter requirements before signing. A notary should not proceed if communication is inadequate or the affiant cannot understand the consequences of the declaration.

Does notarization prove that every statement is true?

No. The notary verifies the appearance, identity, signature, oath or acknowledgment, and voluntariness required for the notarial act. The notary does not investigate and certify that every factual claim is correct.

Proper notarization ordinarily gives the document the status and evidentiary presumptions associated with a public document. But an affidavit may still be challenged for falsity, lack of personal knowledge, hearsay, coercion, forgery, legal insufficiency, or inconsistency with other evidence. Depending on the proceeding, the affiant may still have to testify and undergo cross-examination.

Conversely, defective notarization does not always make the underlying writing automatically void. It may instead be treated as a private document whose authenticity and execution must be proved. Where an oath or prescribed affidavit is an essential statutory or procedural requirement, however, the defect may cause rejection, dismissal, loss of a remedy, or a need to execute a replacement. The result depends on the governing law and the purpose of the document. See Dela Rama v. Papa, G.R. No. 142309.

Filing deadlines and how long an affidavit remains valid

There is no universal filing deadline or expiry period for all affidavits. Notarization itself ordinarily does not expire, but:

The receiving office may require an affidavit executed within a specified recent period.
The affidavit may become inaccurate when circumstances change.
A court, prosecutor, agency, contract, or statute may impose a strict filing deadline.
A notary’s commission and the affiant’s ID must be current on the date of notarization.

Notarizing before a deadline does not constitute filing. Preserve proof that the correct office actually received the affidavit on time.

A judicial affidavit is a specialized example. Under the Judicial Affidavit Rule, the parties generally file and serve judicial affidavits and exhibits no later than five days before the relevant pre-trial, preliminary conference, or scheduled hearing. In covered criminal cases, an accused who chooses to submit defense judicial affidavits generally has 10 days from receipt of the prosecution affidavits. The rule contains limited relief for a first late submission based on a valid reason, absence of undue prejudice, and payment of the prescribed fine. A judicial affidavit also has special content and lawyer-attestation requirements; an ordinary affidavit is not a substitute.

Practical step-by-step checklist

Ask for the current form. Get it directly from the court, prosecutor, agency, bank, insurer, school, embassy, or other recipient.
Confirm the deadline and filing channel. Ask whether the original, a certified copy, or an electronically notarized document is required.
Collect supporting evidence. Gather records before drafting so dates, names, amounts, and reference numbers are accurate.
Write only facts you can truthfully swear to. Separate personal observations from information supplied by another person.
Identify attachments clearly. Refer to each attachment in the affidavit and keep the pages together.
Review every material detail. Check spelling, identity numbers, dates, addresses, property descriptions, and amounts.
Bring proper identification. Use a current official-agency ID bearing both photograph and signature, unless the notary genuinely knows you personally.
Appear and sign correctly. For a paper jurat, sign and take the oath in the notary’s physical presence.
Sign the register. The principal and any required identification or signing witnesses must complete the appropriate register entries.
Inspect the jurat and seal. Do not accept a notarial certificate with unexplained material blanks.
Obtain a receipt and complete copy. A notary who charges fees must issue a BIR-registered receipt and display the fee schedule.
File separately and preserve proof. Keep the receiving stamp, registry receipt, courier tracking, or electronic acknowledgment.

Electronic copies under the amended paper-notarization rules

The Supreme Court’s 2025 amendments to the 2004 Notarial Rules, implemented through OCA Circular No. 197-2025, added electronic recordkeeping and reporting safeguards.

Unless the signatory waives transmission, the notary must, at no additional cost, transmit the prescribed electronic duplicate through email or another mutually agreed electronic file-sharing mechanism within the period stated in the rules—five days from completion of the notarial act or from the applicable deadline for transmitting the duplicate original to the clerk of court.

Compare the received file promptly with the document in your possession. If a material discrepancy affects any party’s rights, notify the notary in writing immediately and request correction. Do not casually waive the electronic copy in a high-value or disputed transaction.

No additional fee may be charged for digitizing, transmitting, storing, or processing the notarial document under these amendments.

Evidence to preserve

Keep:

The complete original affidavit, including its jurat and attachments;
A clear scan or photograph of every page;
The electronic duplicate received from the notary;
The ID presented and proof that it was valid on the notarization date;
The notary’s receipt and contact details;
Drafts or source records that support dates, amounts, and factual statements;
Emails arranging any electronic-copy transmission;
Written notices of discrepancies and the notary’s response;
Filing receipts, receiving stamps, courier records, or electronic acknowledgments; and
Messages or evidence showing coercion, forgery, substitution of pages, or unauthorized alterations, if any.

Do not alter the notarized original. If a material fact is wrong or later changes, ask the receiving office whether it requires a new, corrective, or supplemental affidavit. A material change made after notarization should not be passed off as part of the document originally sworn to.

Common mistakes to avoid

Using an acknowledgment when a jurat is required.
Signing a jurat before meeting the notary.
Sending a representative instead of the affiant.
Using only a cedula for identification.
Presenting an expired ID or one without both photograph and signature.
Leaving dates, amounts, attachments, or material paragraphs blank.
Asking for backdating or using a false place of notarization.
Using a lawyer whose notarial commission is expired or does not cover the territory.
Using a notary who is disqualified by relationship or interest.
Assuming an ordinary Zoom call is valid remote notarization.
Treating notarization as proof that the document is legally sufficient or factually correct.
Changing pages or material wording after notarization.
Confusing the notarization date with the filing date.
Missing a court or agency deadline while trying to perfect a nonessential detail.

False affidavits and perjury

Never sign an affidavit containing a statement you know is false. Do not guess, exaggerate, conceal a material fact, or adopt another person’s account as personal knowledge.

As amended by Republic Act No. 11594, Article 183 of the Revised Penal Code penalizes knowingly making an untruthful statement under oath or in an affidavit on a material matter before an authorized person when the law requires it. The prescribed imprisonment is prision mayor in its minimum period. The statute also provides enhanced consequences for a public officer or employee, a fine of up to ₱1,000,000, and perpetual absolute disqualification from holding an appointive or elective government position.

Whether a particular error constitutes perjury depends on materiality, knowledge, intent, the legal purpose of the affidavit, and the surrounding evidence. Correct an honest mistake promptly and transparently; do not conceal it by substituting pages.

Affidavits signed abroad

For an affidavit intended for use in the Philippines, common routes include:

Signing before a Philippine embassy or consulate, subject to that post’s appointment, personal-appearance, passport, copy, witness, and fee requirements;
Signing before a competent local notary or official in the foreign country, followed by an Apostille if that country is a party to the Apostille Convention; or
Authentication or legalization under the applicable chain if the country is not covered by the Convention.

An Apostille authenticates the origin of the public document; it does not certify that the affidavit’s factual contents are true. Requirements vary by country and intended use. Check the foreign authority, the Philippine receiving office, and the DFA’s Apostille FAQ and documentary requirements before execution.

When legal help is urgent

Consult a Philippine lawyer immediately when:

A court, prosecutor, immigration, election, tax, labor, or administrative deadline is near;
The affidavit could expose you or another person to criminal, civil, tax, or administrative liability;
You are being asked to retract, waive, desist, confess, or admit liability;
The matter concerns land, inheritance, corporate authority, a substantial loan, a minor, immigration status, or foreign use;
A signature, seal, page, attachment, date, or register entry appears forged or altered;
The supposed affiant did not personally appear;
Someone is pressuring an elderly, ill, detained, or vulnerable person to sign;
The affiant cannot understand the language or consequences of the document;
The affiant is abroad and the deadline is approaching; or
A filed affidavit contains a material error or false statement.

PAO assistance may be available to qualified persons. Court and agency deadlines should not be allowed to lapse while eligibility or representation is being arranged.

Frequently asked questions

Can I use a cedula as my only ID?

Generally, no. A cedula does not contain the photograph and signature required for competent evidence of identity. Bring a current qualifying official-agency ID.

Can I sign the affidavit before going to the notary?

For a jurat, the required signature must be made in the notary’s presence. If you already signed, tell the notary and follow the notary’s instructions for signing again.

Can a relative bring my signed affidavit to a notary?

No. The affiant must personally appear and take the oath. A representative cannot supply the affiant’s appearance or personal knowledge.

Can any lawyer notarize my affidavit?

No. The lawyer must have a valid notarial commission and act within its territorial and other limitations. Electronic notarization additionally requires an electronic notarial commission and an accredited facility.

Can a barangay captain notarize an ordinary private affidavit?

Not merely by virtue of being punong barangay. A barangay official may administer only oaths or perform functions specifically authorized by law. If the recipient requires notarization, use a duly commissioned notary unless the governing rule expressly authorizes the official to administer that particular oath.

Can an affidavit be notarized online?

Yes, if it is an electronic document processed under the Supreme Court’s electronic-notarization rules through an accredited facility and a commissioned Electronic Notary Public. An emailed scan or informal video call is insufficient.

Does a notarized affidavit expire?

There is no general expiry period. The receiving office may impose a recency requirement, and changed facts may make an older affidavit inaccurate or unusable.

Does notarization guarantee that an affidavit will be accepted?

No. The affidavit must also satisfy the governing statute, rule, required form, filing deadline, evidentiary requirements, and receiving-office instructions.

Do I need a lawyer to prepare an affidavit?

Not always, but legal drafting is advisable when rights, liability, property, criminal allegations, court proceedings, immigration, substantial money, or complicated facts are involved. The notary’s role does not automatically include advising you on the affidavit’s legal effect.

What should I do if the notarized affidavit contains an error?

Do not erase, overwrite, replace a page, or use correction fluid on the notarized original. Ask the receiving office or a lawyer whether a newly executed, corrective, or supplemental affidavit is required.
