Quick answer

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

State facts truthfully, clearly, and preferably from personal knowledge.
Use the form required by the court, agency, employer, bank, school, or other recipient.
Bring the complete, unsigned affidavit and supporting documents to a duly commissioned notary public.
Personally appear before the notary.
Present competent proof of identity unless personally known to the notary.
Sign 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 records the act in the notarial register.

A cedula or Community Tax Certificate alone is not competent proof of identity. A photocopied signature, a document signed through another person, or an ordinary video call with a notary does not satisfy traditional notarization rules. Remote notarization is possible only under the Supreme Court’s formal electronic-notarization system.

The exact contents, attachments, number of copies, filing method, fee, and deadline depend on the affidavit’s purpose. Ask the receiving office for its latest form and checklist before signing.

What an affidavit does—and does not do

An affidavit identifies the affiant and records factual statements that the affiant swears or affirms are true. Common examples include affidavits of loss, discrepancy, support, consent, complaint, desistance, identity, and one-and-the-same-person affidavits.

Notarization does not automatically prove that every statement is true. It principally authenticates the performance of the notarial act: the affiant appeared, was properly identified, signed in the required manner, and took an oath or affirmation. The Supreme Court has emphasized that notarization by itself does not guarantee the validity of a document’s contents.

A properly notarized document ordinarily enjoys a presumption of regularity regarding its due execution, but that presumption may be overcome by clear and convincing evidence. A forged document remains void even if it appears notarized, as the Supreme Court has reiterated.

An affidavit is also not automatically conclusive evidence in court. Outside procedures that expressly permit affidavit evidence, the affiant may still have to testify and undergo cross-examination. The Court has explained that affidavits are generally treated as hearsay when the affiant does not testify, subject to the Rules of Evidence and applicable exceptions.

What the affidavit should contain

There is no single form for every affidavit. Unless a prescribed form says otherwise, a sound affidavit normally contains:

The proper caption or title.
The place or venue, such as “Republic of the Philippines, City of ___.”
The affiant’s complete name and relevant personal circumstances.
A statement that the affiant is competent to testify to the matters stated.
Numbered paragraphs presenting specific facts in chronological order.
An explanation of how the affiant personally knows each material fact.
Identification of documents referred to, with clearly marked attachments when needed.
The precise purpose for which the affidavit is executed.
A truth declaration.
The affiant’s signature.
A complete jurat for the notary.

Use exact names, dates, addresses, amounts, document numbers, and descriptions. If a statement is based on a record rather than direct observation, identify the record and explain the affiant’s basis for relying on it. Do not present rumor, assumption, or another person’s statement as personal knowledge.

An affidavit should not contain blank spaces that could later be filled in. Mark genuinely inapplicable fields “N/A” when the prescribed form permits it. The 2004 Rules on Notarial Practice prohibit notarization of a blank or incomplete document or one without an appropriate notarial certificate.

Jurat versus acknowledgment

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

For a traditional jurat, the affiant:

Personally appears before the notary on a single occasion.
Presents the affidavit.
Is personally known to the notary or identified through competent evidence of identity.
Signs in the notary’s presence.
Takes an oath or affirmation concerning the affidavit.

An acknowledgment is different. It generally involves a person declaring that an instrument already executed is their free and voluntary act or deed. Acknowledgments are commonly used for deeds, contracts, and powers of attorney. Using an acknowledgment where the receiving rule requires a sworn affidavit may result in rejection.

Do not complete or alter the notarial certificate yourself. The notary must enter the correct act, place and date, identification information, register details, commission particulars, signature, and seal.

Identification requirements

If the affiant is not personally known to the notary, the traditional rules require competent evidence of identity. The usual route is at least one current identification document issued by an official agency and bearing the individual’s photograph and signature. Examples recognized in the rules include passports, driver’s licences, PRC IDs, SSS or GSIS cards, and other qualifying government-issued credentials.

Bring the original ID, not merely a photograph or photocopy. The name and signature should be consistent with the affidavit. If they differ because of marriage, a clerical discrepancy, or another legitimate reason, bring records explaining the difference and ask the recipient whether a separate affidavit or supporting certificate is required.

A Community Tax Certificate or cedula alone is insufficient because it does not carry the photograph-and-signature safeguards required by the rules. The Supreme Court has repeatedly applied this requirement, including in Ko v. Uy-Lampasa.

The rules provide a limited alternative when a qualifying ID is unavailable:

One credible witness who is personally known to the notary, personally knows the affiant, and is not a party or privy to the document or transaction; or
Two credible witnesses who personally know the affiant, are not privies to the document or transaction, and present qualifying documentary identification to the notary.

This is not a shortcut based on any available companion. Confirm the arrangement with the notary in advance.

How to complete traditional paper notarization

1. Confirm the recipient’s requirements

Before drafting, ask the court, prosecutor, agency, bank, school, employer, insurer, or foreign authority:

Whether it has a prescribed form.
Whether notarization is required.
Which statements and attachments must be included.
Whether originals or certified copies are needed.
How many copies must be filed.
Whether witnesses are required.
Whether electronic notarization is accepted.
What filing or submission deadline applies.

A generic affidavit may be legally sworn yet still be rejected for failing to meet a special requirement.

2. Assemble the facts and evidence

Prepare a timeline and collect records that support each material statement. Depending on the matter, these may include:

Government IDs and civil-registry records.
Receipts, invoices, contracts, or account statements.
Messages, emails, call logs, photographs, or videos.
Police, barangay, medical, employment, or school records.
Proof of delivery, filing, or payment.
The document referred to in an affidavit of loss or discrepancy.

Preserve original electronic files and metadata where relevant. Do not edit screenshots in a way that removes dates, account names, URLs, or surrounding context.

3. Review the finished document

Check every page, paragraph, attachment reference, name, date, and amount. Read translations as well as the principal text. Do not sign a statement you do not understand.

4. Appear before a commissioned notary

For traditional notarization, go personally to the notary’s regular place of work or business within the territorial area of the commission. The rules permit limited off-site notarization within that territory in specified situations, including certain public functions, hospitals, and detention facilities.

A traditional notary must not notarize for an absent signer. The notary must also refuse when there is reason to believe the act is unlawful or immoral, the signer does not understand its consequences, or the signer is not acting voluntarily.

A notary is disqualified when, among other circumstances, the notary is a party to the document, has a prohibited interest in the transaction, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative within the fourth civil degree.

5. Sign and take the oath

Bring the unsigned affidavit unless the notary has instructed otherwise under a governing procedure. Sign only when directed, then take the oath or affirmation. Each affiant in a joint affidavit must personally complete the required process.

6. Inspect the completed notarization

Before leaving, check that:

The jurat is complete.
The date and place are correct.
The affiant’s name and identification details are accurate.
The notary signed and affixed a legible official seal.
The document shows its notarial register entry, page, book, and series details.
There are no unexplained blanks or alterations.
All pages and attachments are present.

Request a BIR-registered receipt. Keep a clear copy of the entire notarized document, including every attachment.

Signers who cannot use an ordinary signature

The traditional rules allow special procedures, but safeguards apply.

A person using a thumbmark or other mark must affix it in the presence of the notary and two disinterested and unaffected witnesses. The witnesses sign, and the notary adds the certification required by the rules.

If a person is physically unable to sign or make a mark, the notary may sign on that person’s behalf only upon the person’s direction and in the presence of two disinterested and unaffected witnesses, with the required wording and notarization.

Arrange this with the notary beforehand. If capacity, communication, coercion, or authority is disputed, obtain legal advice before proceeding.

Electronic and remote notarization

The 2025 Rules on Electronic Notarization supplement traditional notarization. They authorize commissioned Electronic Notaries Public to perform in-person electronic notarization, remote electronic notarization, or a combination of both through an accredited Electronic Notarization Facility.

Important limits include:

The rules apply to electronic documents in PDF or PDF/A format.
Paper documents bearing handwritten signatures continue to follow the traditional rules.
Notarial wills and depositions are excluded from electronic notarization.
Remote notarization must use the authorized facility, identity checks, electronic signatures, audiovisual communication, and other required safeguards.
A prerecorded video or an informal video call with an ordinary notary is not a compliant remote notarization.
An Electronic Notary Public may serve principals located anywhere in the Philippines.
A principal abroad may use remote electronic notarization only under the rules’ limited arrangement while physically within a Philippine embassy, consular office, or honorary-consul office and after the required location confirmation.

Use the Supreme Court’s Electronic Notary Services portal to check current services, rules, forms, and official guidance. Confirm that the intended recipient accepts an electronically notarized affidavit before paying or signing.

Affidavits signed abroad

A person abroad should first ask the Philippine recipient what authentication chain it requires. Depending on the country and transaction, the acceptable route may include:

Execution before a Philippine embassy or consulate that offers notarial services;
Execution before a competent local notary followed by an apostille in a country where the Apostille Convention applies; or
Local notarization followed by the required authentication or consular legalization for a non-Apostille country.

Requirements and appointments vary by foreign post. Consult the particular embassy or consulate rather than relying on another post’s checklist.

For Philippine documents intended for use abroad, check the destination country’s requirements and the DFA Authentication Division. An apostille authenticates the origin of the public document—including the relevant signature, capacity, and seal—not the truth of the affidavit’s factual contents.

Special court and agency affidavits

A special affidavit may carry requirements beyond ordinary notarization.

Under the Judicial Affidavit Rule, a judicial affidavit generally uses a structured question-and-answer format, identifies the examining lawyer, includes the required lawyer’s attestation, and takes the place of direct testimony. Judicial affidavits and attached exhibits generally must be filed and served no later than five days before the pre-trial, preliminary conference, or scheduled hearing on a motion or incident.

Late submission is ordinarily treated as a waiver. A court may allow it only once when there is a valid reason, no undue prejudice, and payment of a discretionary fine of ₱1,000 to ₱5,000. Other criminal, civil, administrative, immigration, procurement, employment, and regulatory proceedings have their own forms and deadlines.

A complaint-affidavit, counter-affidavit, affidavit of desistance, or affidavit affecting property or civil status should not be treated as a harmless template. Its wording can affect rights, defenses, evidence, and filing periods.

Fees, validity, and deadlines

There is no single peso amount, expiration period, filing deadline, or monetary threshold that applies to every affidavit.

The traditional rules permit prescribed notarial fees, require a notary who charges fees to issue a BIR-registered receipt, and require the fee schedule to be displayed at the office. Agreed travel expenses may be separate. Document drafting, consultation, translation, authentication, apostille processing, and filing may involve services distinct from the notarial act; ask for an itemized quotation.

Under the 2025 amendments to traditional reporting rules, notaries may not charge clients additional fees for digitizing, transmitting, or processing the notarial records that the notary is required to submit.

An affidavit does not necessarily “expire” merely because time has passed. It may become stale, unacceptable, or inaccurate because the receiving authority imposes a recency requirement or because circumstances have changed. Never reuse an old affidavit if its facts are no longer true.

The governing deadline is usually the deadline for the underlying transaction, application, complaint, response, or court filing—not the date of notarization itself.

Evidence to preserve

Keep:

The complete notarized original or an exact, legible copy.
Copies of all IDs shown, stored securely.
Every attachment in the same order as filed.
Drafts showing material corrections.
The official receipt.
Filing acknowledgments, tracking records, and email confirmations.
The recipient’s form, checklist, or written instructions.
For electronic notarization, the final PDF/A, verification information, and permitted recording or transaction record.
Contemporaneous records supporting the affidavit’s facts.

If fraud or unauthorized notarization is suspected, preserve the questioned document in its original condition. Do not write on it, remove pages, or alter the electronic file.

Common mistakes and warning signs

Avoid:

Signing before meeting the traditional notary.
Sending only a signature page for notarization.
Allowing a fixer, clerk, relative, or lawyer’s employee to notarize in the notary’s absence.
Using another person’s ID or a cedula as the only identification.
Leaving dates, names, amounts, or attachment references blank.
Swearing to facts learned only from rumor without identifying the source.
Attaching altered screenshots or incomplete message threads.
Using an acknowledgment when a jurat is required.
Backdating or asking the notary to state that an absent person appeared.
Using a random “online notary” outside the Supreme Court’s electronic-notarization framework.
Assuming notarization cures an illegal, forged, unauthorized, or substantively defective transaction.
Missing the filing deadline while concentrating only on notarization.

A false statement in an affidavit can have serious consequences. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making an untruthful statement under oath on a material matter in a legally required affidavit may constitute perjury. The law provides potential imprisonment, a fine of up to ₱1 million, and additional consequences. Liability depends on the statutory elements and the proven facts; falsification, fraud, contempt, or administrative liability may also arise in an appropriate case.

When legal help is urgent

Seek a Philippine lawyer promptly when:

A court, prosecutor, police office, regulator, or employer has given a deadline.
You are being asked to admit wrongdoing, waive rights, withdraw a complaint, or sign an affidavit of desistance.
The affidavit concerns land, inheritance, corporate authority, substantial debt, immigration, custody, abuse, or criminal allegations.
Someone signed, altered, or notarized a document in your name without your appearance.
The notary’s commission, seal, register information, or identity appears questionable.
You are being pressured, threatened, or asked to backdate the document.
An earlier affidavit contains a material error or conflicts with another sworn statement.
The affiant is a minor, cannot understand the document, cannot communicate independently, or may lack decision-making capacity.

Qualified persons may approach the Public Attorney’s Office, the IBP National Center for Legal Aid, or another accredited legal-aid provider.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily sworn or affirmed before a person authorized to administer an oath. However, some laws, court rules, and agency procedures accept a different certification or unsworn declaration. Follow the specific recipient’s rule rather than notarizing unnecessarily.

Must a lawyer draft an affidavit?

Not always. A prescribed or straightforward form may be completed by the affiant. Legal review is advisable when rights, liability, contested facts, substantial property, or a pending case is involved.

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

For a traditional jurat, the signature must be made in the notary’s presence. If already signed, expect the notary to require proper re-execution; do not assume that merely confirming an old signature is sufficient.

Can a relative bring my signed affidavit to the notary?

No. A representative cannot replace the affiant’s required personal appearance.

Are witnesses always necessary?

No. An ordinary affidavit does not automatically require subscribing witnesses. Witnesses may be required by a special form or law, as identity witnesses, or when the signer uses a mark or cannot sign.

Is one government ID always enough?

One current official ID bearing the required photograph and signature can satisfy the general traditional rule, but the notary and receiving authority must verify that it qualifies. A special transaction may require additional identification.

Is a cedula a valid notarial ID?

Not by itself. Supreme Court rulings hold that a Community Tax Certificate does not satisfy the photograph-and-signature requirement for competent evidence of identity.

Can an affidavit be notarized through Zoom?

Not through an informal video call. Remote electronic notarization must be performed by a commissioned Electronic Notary Public through an accredited facility and in compliance with the 2025 rules.

Does notarization make a false statement true?

No. Notarization does not cure falsehood, forgery, lack of authority, illegality, or lack of consent.

Does a notarized affidavit expire?

There is no universal expiration date. The recipient may impose a recency period, and the affidavit should not be used once its material facts have changed.

Can an incorrect affidavit simply be edited after notarization?

No material text should be added or changed after notarization. Prepare a corrected or supplemental affidavit, disclose the earlier error where appropriate, and comply with the relevant filing rules.
