Quick answer

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

Complete the affidavit without material blanks.
Personally appear before a commissioned notary public.
Prove identity through competent evidence of identity, unless personally known to the notary.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its contents are true.
Sign or mark the notarial register.

An affidavit normally uses a jurat, not an acknowledgment. A signed paper sent through email, handed over by a relative, or “notarized” without the affiant appearing is not compliant traditional notarization. Electronic or remote notarization is permitted only under the Supreme Court’s separate rules, through a commissioned Electronic Notary Public and an accredited electronic notarization facility.

Notarization does not prove that every statement is true, cure a defective document, transfer ownership, create authority that the signer does not have, or file the affidavit with the court or agency that requested it.

What makes a document an affidavit?

A proper affidavit identifies the person making the statement—the affiant—and sets out facts that the affiant swears or affirms are true.

There is no single mandatory format for every affidavit. The requesting court, prosecutor, bank, employer, school, insurer, local civil registrar, or government agency may prescribe its own form and supporting documents. As a practical minimum, an affidavit should contain:

The affiant’s complete name, relevant personal details, and address.
A clear statement that the affiant is executing the document under oath.
Separately numbered factual statements.
Exact names, dates, places, amounts, and document references where material.
The purpose for which the affidavit is being executed.
Properly identified attachments or annexes.
The affiant’s signature over the printed name.
A complete jurat executed by the notary or other officer authorized to administer the oath.

State facts within personal knowledge. If a statement comes from a record, identify the record and explain how the affiant knows or has custody of it. Do not present assumptions, rumors, or legal conclusions as observed facts.

Jurat, acknowledgment, and witnessing are different

Notarial act	What the signer does	Common use
Jurat	Appears personally, is identified, signs in the notary’s presence, and takes an oath or affirmation about the document	Affidavits and sworn statements
Acknowledgment	Appears personally and declares that an existing signature was voluntarily affixed and, when applicable, that the signer had authority to act in a representative capacity	Deeds, contracts, and powers of attorney
Signature witnessing	Signs in the notary’s presence after being identified	Documents requiring witnessed execution but no oath
Copy certification	Presents a document that the notary may lawfully copy-certify	Limited private documents

Calling an acknowledgment an “affidavit” does not make its factual contents sworn. Conversely, adding “subscribed and sworn” without actually administering an oath and requiring the proper appearance does not create a valid jurat.

A notary generally may not copy-certify a vital record, court record, or public record when certified copies are available from its official custodian. Obtain PSA certificates, court records, land records, and similar documents from the issuing or custodial agency.

Personal appearance is mandatory for a paper affidavit

Under the amended 2004 Rules on Notarial Practice, traditional notarization remains the system for paper documents bearing handwritten signatures or marks.

For an affidavit, the affiant must appear before the notary on the occasion of notarization, sign in the notary’s presence, and take the oath or affirmation. The following arrangements are serious warning signs:

Leaving a signed affidavit with a notary’s secretary.
Sending only a scan, photograph, or photocopy.
Having a relative or representative appear for the affiant.
Receiving a seal and notarial details without meeting the notary.
Paying for a pre-signed or pre-sealed blank form.
Backdating the jurat.
Using another person’s identification.
Notarizing for an absent, incapacitated, or deceased person.

A regular paper notary’s authority is territorial. The notary ordinarily acts within the city or province covered by the commissioning court and at the notary’s regular place of work, subject to the limited places and circumstances allowed by the rules.

What identification should the affiant bring?

For traditional paper notarization, competent evidence of identity generally means at least one current identification document issued by an official agency and bearing the affiant’s photograph and signature. Examples in the rules include a passport, driver’s license, PRC ID, government office ID, SSS or GSIS card, senior citizen ID, seafarer’s book, and alien registration documentation.

Bring the original ID. A notary or receiving institution may reasonably request an additional ID or supporting record where names, signatures, photographs, addresses, or other details do not match.

A community tax certificate or cedula is not sufficient by itself as competent evidence of identity. The Supreme Court has emphasized that it does not meet the required photo-and-signature safeguards. Likewise, do not assume that an ID without a visible signature will satisfy the literal identification requirement for paper notarization; ask the notary in advance and bring another qualifying ID if available.

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

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

These are identity witnesses, not substitute affiants and not automatically the same as witnesses required for a particular deed or transaction.

Step-by-step checklist

Before visiting the notary

Ask the recipient for its exact requirements. Confirm the prescribed form, purpose, number of originals, required annexes, acceptable language, recency requirement, and filing deadline.
Check whether an affidavit is actually required. Some transactions need an acknowledgment, verification, certification, statutory declaration, or agency form instead.
Review every statement. Correct misspellings, inconsistent names, wrong dates, and unsupported claims.
Complete or strike out material blanks. Do not sign a document that can later be completed differently.
Arrange the annexes. Label them consistently and bring originals where comparison may be required.
Bring the original qualifying ID. Bring supporting civil-registry or corporate-authority records if names or representative capacity are relevant.
Do not sign the jurat affidavit in advance. Sign when instructed by the notary.

During notarization

The notary should personally:

Examine the affidavit and the affiant’s identity.
Determine that the document is complete enough for the requested act.
Check that the affiant understands the document and is acting voluntarily.
Witness the signature or permitted mark.
Administer the oath or affirmation.
Make the required contemporaneous entry in the notarial register.
Require the affiant and applicable witnesses to sign or mark the register.
Complete, sign, and seal the notarial certificate.

Read the completed document before leaving. Check the venue, date, affiant’s name, ID information, jurat wording, notary’s commission details, and the Document, Page, Book, and Series entries.

After notarization

Keep an exact copy of the complete affidavit and every annex.
Obtain and retain any official receipt.
Record when, where, and to whom the affidavit was submitted.
Secure proof of filing, delivery, or electronic acknowledgment from the actual recipient.
Protect copies of IDs and other personal data against unnecessary disclosure.

The 2025 amendments also require the notary, at no additional cost, to transmit the prescribed electronic duplicate-original copy to each signatory within the period stated in the amended rules, unless the signatory waives transmission. If the electronic copy differs materially from the document in your possession, notify the notary promptly in writing and preserve both versions.

Online and electronic notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement rather than replace traditional notarization. They cover electronic documents and allow:

In-Person Electronic Notarization;
Remote Electronic Notarization; and
A permitted hybrid arrangement.

Electronic notarization must use a Supreme Court-accredited Electronic Notarization Facility and a lawyer specifically commissioned as an Electronic Notary Public. A traditional paper-notary commission does not automatically authorize electronic notarization.

For remote electronic notarization, the electronic process must satisfy the rules on identity, location, live audiovisual appearance, electronic signatures, records, and the notarial certificate. A principal outside the Philippines may use the limited arrangement allowed when located within the premises of a Philippine embassy, consular office, or Philippine honorary consul, subject to the rule’s safeguards.

A scanned wet-signed affidavit emailed to an ordinary notary is not automatically an electronically notarized document. The 2020 interim rules for remotely notarizing paper documents have been repealed. For current accredited providers and participating electronic notaries, check the Supreme Court’s eNotary Services portal.

Special situations and exceptions

Affidavits signed abroad

A person abroad may ordinarily execute the affidavit before:

A Philippine embassy or consulate providing notarial services;
A competent local notary, followed by an apostille where the relevant countries and document are covered by the Apostille Convention; or
The authentication or legalization process required for a non-Apostille destination.

The intended recipient determines what it will accept. Notarization alone may be insufficient for international use. Review the DFA’s current Apostille documentary requirements before paying or sending documents.

Persons unable to sign conventionally

The notarial rules contain safeguards for a signature by mark and for a person physically unable to sign. Additional witnesses, notarial statements, or assistance may be necessary. Tell the notary beforehand about visual, hearing, mobility, literacy, language, or communication needs. The notary must still be satisfied about identity, understanding, voluntariness, and the required act.

Corporate or representative affidavits

An officer or representative should identify:

The entity represented;
The affiant’s position;
The source and limits of authority;
Whether the facts are personally known or taken from records under the affiant’s custody; and
The board resolution, secretary’s certificate, special power of attorney, or other authority required by the recipient.

Notarization does not supply missing corporate or agency authority.

Judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, it must contain consecutively numbered questions and answers, information about the examining lawyer, the witness’s source of knowledge, identification of evidence, a jurat, and the lawyer’s sworn attestation.

Subject to the rule and court orders, judicial affidavits and exhibits are generally filed and served not later than five days before the pre-trial, preliminary conference, or scheduled hearing for a motion or incident. Late submission is normally treated as waived, although a court may allow it once for a valid reason, without undue prejudice, and upon payment of the prescribed fine. Obtain legal help early rather than using a generic affidavit form.

Deadlines, validity, and filing

There is no universal rule that every notarized affidavit expires after three or six months. Its usefulness may nevertheless end because:

The requesting institution imposes a recency requirement.
The facts have changed.
The underlying application or proceeding has a deadline.
The affidavit was prepared for a different purpose.
A court order or special rule requires another form.
An ID or supporting authorization was invalid when used.

Notarization and filing are separate acts. A notary’s reporting obligations to the Clerk of Court do not submit your affidavit to the prosecutor, court, bank, insurer, civil registrar, or other intended recipient. Use the recipient’s authorized filing counter, court system, portal, email address, courier procedure, or other official channel, and retain proof of timely submission.

What notarization does—and does not do

Proper notarization converts a private document into a public document for evidentiary purposes and gives rise to important presumptions concerning its execution and authenticity. It does not make the statements immune from challenge.

An irregular notarization can strip the document of its public character and reduce it to a private document requiring separate proof of due execution and authenticity. Whether the underlying act or transaction also becomes invalid depends on the law governing that particular document. Some transactions remain valid between the parties despite defective notarization; others, such as transactions for which a public instrument is an essential legal form, may be affected more seriously.

A notary certifies the notarial act—not the ultimate truth of every factual assertion. A court or agency may still require supporting records, testimony, cross-examination, or other competent evidence.

Knowingly and deliberately making a material false statement under oath may expose the affiant to perjury or other criminal, civil, administrative, employment, or procedural consequences. Correct an honest error through the proper recipient and legal process; do not silently alter a notarized original.

Evidence to preserve

Keep the following, especially when the affidavit concerns money, property, employment, an accident, a crime, family relations, identity, or a filing deadline:

The complete notarized original and electronic copy.
All annexes in the condition submitted.
Earlier drafts showing legitimate corrections.
The original records supporting each important statement.
Photographs, messages, emails, call records, receipts, and transaction records.
File metadata and unedited source files for electronic evidence.
The identity and contact details of persons with direct knowledge.
The notary’s name, office address, commission details, and notarial reference numbers.
Proof of filing, service, payment, and receipt.
Written notice of any discrepancy in the electronic duplicate-original copy.

Preserve evidence lawfully. Do not access another person’s account, device, records, or private communications without authority.

Common mistakes

Using an acknowledgment when a jurat is required.
Signing a paper affidavit before meeting the notary.
Treating a cedula as sufficient identification.
Leaving blank names, dates, amounts, or descriptions.
Copying an online template without checking the recipient’s form.
Swearing to facts known only through rumor.
Failing to explain inconsistent names or civil-registry entries.
Attaching unreadable screenshots or uncertified public records.
Assuming notarization corrects a forged signature or lack of authority.
Altering, replacing, or adding pages after notarization.
Using a notary whose commission has expired or whose territorial authority does not cover the act.
Paying someone who offers notarization without personal or authorized electronic appearance.
Missing the actual filing deadline after obtaining the notarization.
Assuming an affidavit prepared for Philippine use will automatically be accepted abroad.

When legal help is urgent

Consult a Philippine lawyer promptly if:

A court, prosecutor, regulator, or government deadline is approaching.
The affidavit may admit a crime, debt, breach, negligence, fraud, or other liability.
You are being pressured to sign, omit facts, backdate, or use another person’s ID.
The document concerns land, inheritance, custody, immigration, corporate control, or a special power of attorney.
A signer lacked capacity, was absent, or was already deceased on the stated date.
A signature, seal, notarial certificate, or electronic copy appears forged or altered.
The notarial entry cannot be verified or refers to a different document.
You need to withdraw or correct a material sworn statement.
The affidavit will be used outside the Philippines.
A receiving office has rejected the affidavit and the deadline is still running.

For suspected notarial irregularities, preserve the original and ask the Office of the Clerk of Court of the RTC in the notary’s commissioning jurisdiction about verifying the commission and notarial record. A verified complaint and separate lawyer-disciplinary, civil, or criminal remedies may be available depending on the evidence.

Frequently asked questions

Can I sign an affidavit before going to the notary?

For a jurat, the affiant must sign in the notary’s presence. If it is already signed, tell the notary; the notary may require a fresh signature or a properly re-executed document.

Is one valid ID enough?

The paper rule refers to at least one qualifying current official ID bearing a photograph and signature. A notary or recipient may require more where identity, signature, capacity, or name consistency is genuinely in question.

Do I always need two witnesses?

No. Two witnesses are not a universal affidavit requirement. They may be needed as credible identity witnesses, for signing by mark, or because the particular document or transaction independently requires them.

Can someone else have my affidavit notarized for me?

No. A representative cannot replace the affiant’s required appearance, signature, and oath. A representative may submit the completed affidavit afterward only if the receiving office permits it.

Does a notarized affidavit conclusively prove my claim?

No. It supports identity and sworn execution and may have evidentiary value, but the facts can still be disputed and may require corroborating records or testimony.

Can a paper affidavit be notarized through a video call?

Not as ordinary paper notarization. Use the authorized electronic-notarization framework for an eligible electronic document. The former interim remote-paper rules were repealed.

Does an affidavit expire?

Not automatically under a single general rule. The recipient’s recency policy, changing facts, and the governing filing deadline determine whether it remains acceptable.

Can I change a notarized affidavit?

Do not erase, overwrite, replace pages, or add material after notarization. Prepare a corrected, supplemental, or new affidavit and disclose the earlier version when the applicable procedure requires it.
