Quick answer

A Philippine affidavit is a written statement made under oath or affirmation. For a traditional paper affidavit, the affiant ordinarily must:

Use a complete document with no material blanks.
Personally appear before a commissioned notary public or another officer specifically authorized by law to administer the oath.
Present competent proof of identity.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its material statements are true.
Sign or mark the notarial register.
Receive the document with a completed jurat, the notary’s signature and seal, and the required notarial details.

One current official identification document bearing the holder’s photograph and signature is generally sufficient under the notarial rules. A notary or receiving office may reasonably require additional proof. A community tax certificate or cedula alone is not competent evidence of identity.

There is no universal rule that every legal document must be notarized, no general two-ID requirement, and no fixed expiration period for every affidavit. The governing statute, court rule, agency form, or recipient’s written requirements may impose additional contents, witnesses, supporting documents, validity periods, or filing deadlines.

Affidavit, jurat, and acknowledgment are different

Term	What the signer declares	When the signature is made
Affidavit	The written factual statement is true under oath or affirmation.	Ordinarily signed as part of a jurat.
Jurat	The affiant personally signs and swears or affirms to the document before the notary.	The affiant must sign in the notary’s presence.
Acknowledgment	The signer confirms that an existing signature is theirs and that the instrument is their free and voluntary act or deed.	The instrument may have been signed earlier, but the signer must still personally appear and acknowledge it.

An ordinary affidavit normally requires a jurat, commonly beginning with “Subscribed and sworn to before me.” An acknowledgment is more commonly used for deeds, contracts, powers of attorney, waivers, and similar instruments.

Using an acknowledgment where an oath is legally required may leave the affidavit defective. The 2004 Rules on Notarial Practice define a jurat as requiring personal appearance, identification, signing in the notary’s presence, and an oath or affirmation.

What the affidavit should contain

There is no single format for every affidavit. Start with the form prescribed by the court, prosecutor, agency, bank, school, employer, insurer, or other recipient. Do not replace a required form with a generic affidavit without confirming that it will be accepted.

A properly prepared affidavit will usually contain:

A descriptive title, such as “Affidavit of Loss” or “Complaint-Affidavit.”
The affiant’s complete name and relevant personal circumstances.
The affiant’s address or other identifying information required by the recipient.
Clear, consecutively numbered factual statements.
Dates, places, names, amounts, and document descriptions stated as precisely as the affiant can truthfully provide.
An explanation of how the affiant personally knows each material fact.
References to attachments, with each attachment clearly identified.
A truthful statement of purpose.
The affiant’s signature over their printed name.
The appropriate jurat completed by the notary or authorized officer.

Avoid legal conclusions when the affiant can instead state the underlying facts. If a fact comes from a business, government, medical, or other record rather than direct observation, identify the record and explain the affiant’s basis for relying on it.

Do not guess an exact date, amount, document number, or identity. If the affiant genuinely cannot recall an exact detail, the affidavit should say so accurately and use qualified language such as “on or about” only when appropriate.

Attachments

Refer to each attachment in the affidavit and label it consistently. Preserve the original evidence even if a copy is attached.

Notarizing the affidavit does not automatically certify that every attachment is genuine or that every statement in an attached document is true. A receiving office may separately require an original, certified true copy, registry-certified record, apostille, authentication, translation, or other proof.

Language and understanding

The affiant should understand the language and consequences of the document. If translation or interpretation is needed, arrange it before notarization and ask the recipient whether a certified translation is required.

A judicial affidavit must be prepared in a language known to the witness. If that language is neither English nor Filipino, the Judicial Affidavit Rule requires an English or Filipino translation.

Identity requirements

If the affiant is not personally known to the notary, identity may generally be established through at least one current identification document issued by an official agency and bearing the affiant’s photograph and signature. The rule gives examples such as a passport, driver’s license, PRC ID, SSS card, GSIS e-card, and other qualifying government identification.

The list is not exclusive, but the document must satisfy the rule’s features. Bring the original ID, not merely an unclear photograph or photocopy. The name and signature should reasonably correspond with those in the affidavit.

A cedula alone is insufficient because it does not bear both the photograph and signature required by the rule. The Supreme Court has repeatedly applied this requirement, including in Torrices v. Atty. Munar.

If no qualifying ID is available, the rules provide a credible-witness alternative:

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 documentary identification.

This is not the same as asking any friend or relative to “vouch” for the affiant. The precise conditions must be satisfied, and the notary may refuse if identity cannot be established reliably.

A notary may ask for additional proof when names differ, the ID is damaged, the photograph no longer permits reliable comparison, the affiant signs in a representative capacity, or there are other legitimate identity concerns. A receiving agency may also impose its own documentary requirements.

What must happen during traditional notarization

For a paper affidavit with a handwritten signature:

Bring the complete affidavit. Do not leave names, dates, amounts, property descriptions, or other material terms blank.
Bring the original qualifying ID and any required supporting documents.
Appear before the notary personally. A representative cannot take the oath for the affiant.
Sign in the notary’s presence. Do not pre-sign an affidavit requiring a jurat.
Take the oath or affirmation.
Sign or place the required mark in the notarial register.
Check the completed jurat and notarial details before leaving.
Keep a complete copy, including every page, attachment, and the jurat.

Every affiant in a joint affidavit must personally appear, be properly identified, sign, and take the oath. The presence of only one joint affiant does not permit the notary to notarize for the absent signers.

The notary must refuse to notarize a blank or incomplete document, a document lacking an appropriate notarial certificate, or a transaction the notary knows or has good reason to believe is unlawful or immoral. The notary must also refuse when the signer is not acting freely or does not appear to understand the transaction. These safeguards are emphasized in Supreme Court decisions such as Patenia-Kinatac-an v. Commission on Audit.

Notarial certificate details to check

The concluding portion should identify:

The notary’s name as stated in the commission.
The notarial commission’s serial number.
The city or province for which the notary is commissioned.
The commission’s expiration date.
The notary’s office address.
The notary’s Roll of Attorneys number.
The professional tax receipt details.
The IBP membership number.
The document, page, book, and series numbers corresponding to the notarial register.

The jurat should also reflect the place and date of notarization and the basis for identifying the affiant. The notarial certificate must bear the notary’s signature and official seal. The Supreme Court identified these required concluding details in Kiener v. Atty. Amores.

Missing or obviously inconsistent details are warning signs. They do not allow a reader to decide every question of validity by appearance alone, but they justify verification with the proper Clerk of Court.

Who may administer the oath

A commissioned notary public is the usual choice, but some laws and procedural rules authorize other officials to administer oaths for particular proceedings. For example, a complaint-affidavit in a preliminary investigation may be subscribed before a prosecutor or another government official authorized to administer oaths.

Do not assume that every elected official, police officer, barangay official, lawyer, or government employee may notarize documents or administer an oath for every purpose. Authority must come from a law or rule applicable to that officer and proceeding.

A traditional notary must have a current commission and act within the territorial jurisdiction of that commission. Notarization is ordinarily performed at the notary’s regular place of work or business, subject to the limited locations and circumstances permitted by the rules.

A notary is disqualified when the notary:

Is a party to the document;
Will obtain a prohibited direct or indirect benefit from the transaction; or
Is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

Choose an independent notary when any relationship or interest could create doubt.

Electronic and remote notarization

Electronic notarization is now recognized under A.M. No. 24-10-14-SC, the Rules on Electronic Notarization. It supplements rather than replaces paper notarization.

An electronic document in PDF or PDF/A format may be notarized only by an Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. The authorized modes are:

In-Person Electronic Notarization: the parties physically appear before the electronic notary, but the document and signatures are electronic.
Remote Electronic Notarization: the parties appear through the facility’s live videoconferencing system.
Mixed appearance: some participants appear physically and others remotely, when allowed by the system and rules.

For a jurat by electronic means, the affiant must electronically sign through the facility in the electronic notary’s presence and take the oath. A pre-signed or scanned wet-signed affidavit cannot simply be uploaded and treated as an electronic jurat. Pre-signed electronic documents are treated differently for acknowledgment or affirmation.

Ordinary email, messaging, a recorded video, or an informal Zoom call with a traditional notary does not satisfy the electronic-notarization rules. Use only a commissioned electronic notary and an accredited facility. Notarial wills and depositions are excluded from electronic notarization.

The Supreme Court’s electronic-notarization FAQ explains the permitted documents, account and identity-verification process, location controls, and other safeguards. Because implementation and provider availability may change, confirm the current accredited facilities through the official eNotarization portal before paying or uploading sensitive documents.

Affidavits executed abroad

A person abroad commonly has two routes:

Execute the affidavit before an authorized Philippine consular officer, following the requirements of the relevant embassy or consulate; or
Use a local foreign notary, then obtain the apostille or authentication required for use in the Philippines.

For a document from an Apostille Convention country, an apostille issued by the competent authority of the country of origin generally replaces consular legalization. For a non-Convention country—or where an exception applies—authentication or legalization may still be required. The receiving Philippine office may also require a translation.

Electronic remote notarization has a limited extraterritorial option: the principal abroad must be physically within a Philippine embassy, consular office, or Philippine honorary consul’s office, and a designated officer must confirm the principal’s presence. Availability may be restricted by local law or the facilities of the foreign post.

Requirements, appointments, fees, identification documents, and processing periods vary by post. Check the relevant embassy or consulate and the DFA Apostille guidance before signing.

Affiants who cannot sign normally

A thumbmark or other mark may be used where permitted, with the required notarial safeguards and register entry.

If a person is physically unable to sign or make a mark, the notarial rules allow the notary to sign on that person’s behalf only under strict conditions. The person must direct the notary to sign; two disinterested and unaffected witnesses must be present and sign; the prescribed notation must be placed below the signature; and the notary must complete the proper acknowledgment or jurat. This is not a shortcut for an absent or unwilling affiant.

A person’s disability, illness, age, illiteracy, or inability to speak English does not remove the requirements of identity, voluntariness, awareness, and personal appearance under the applicable mode.

Deadlines and validity periods

An affidavit does not automatically expire after 30, 60, or 90 days. Its usefulness depends on:

Whether its facts remain true;
Whether the recipient requires a recently executed affidavit;
Whether a statute or form specifies a validity period;
Whether the related application, complaint, pleading, claim, or transaction has a deadline; and
Whether a later event has made the affidavit inaccurate or incomplete.

Do not change a notarized affidavit by inserting facts, replacing pages, or altering attachments. If a material correction or update is needed, prepare and execute a new or supplemental affidavit as appropriate.

Court and agency deadlines can be much shorter than any practical “validity” period. Under the Judicial Affidavit Rule, parties generally must file and serve judicial affidavits and exhibits not later than five days before the pre-trial, preliminary conference, or scheduled hearing for a motion or incident. In covered criminal cases, the accused who elects to submit defense judicial affidavits generally has 10 days from receipt of the prosecution’s affidavits. Late submission is ordinarily treated as a waiver, subject to the rule’s narrow one-time relief, valid-reason and no-prejudice requirements, and prescribed fine.

Other affidavits—such as counter-affidavits in preliminary investigations, affidavits supporting urgent motions, insurance claims, procurement submissions, or affidavits for civil-registry transactions—are governed by different deadlines. Follow the notice, order, statute, or official form for the particular proceeding.

Electronic copies and notarial records

Under the 2025 amendments to the paper-notarization rules, traditional notaries have electronic recordkeeping and reporting obligations. Upon mutual agreement, a signatory may receive an electronic copy through email or another agreed file-sharing method without an additional digitization, transmission, or processing charge, subject to the amendment’s transmittal period.

An electronic copy is useful for preservation, but confirm whether the recipient requires the paper original, an electronically notarized original, a certified copy, or a particular file format.

What notarization does—and does not do

Proper notarization provides evidence that the prescribed notarial act occurred. For an acknowledged instrument, it can make the document self-authenticating and provide prima facie evidence of due execution.

It does not mean that:

Every statement in an affidavit is true;
The notary investigated the underlying events;
An attachment is authentic;
The transaction is lawful or enforceable in every respect;
The signer owns the property mentioned;
The affidavit proves the case by itself; or
The document satisfies every filing, registration, tax, or agency requirement.

The Supreme Court clarified in Anido v. People that notarization generally establishes due execution and authenticity, not the truth of an affidavit’s contents. For an affidavit, the notary’s official act concerns the jurat: the appearance, oath, signature, identity, date, and related matters certified by the notary.

An affidavit may still require the affiant’s testimony and cross-examination before it can prove disputed facts in court. A judicial affidavit replaces direct testimony only under the applicable rule, and the witness ordinarily must still appear for cross-examination.

Improper notarization commonly strips a document of the evidentiary advantages of a public document and reduces it to the status of a private document requiring proof of due execution and authenticity. It does not invariably void the underlying transaction. The legal effect depends on whether notarization or a public instrument is required for validity, enforceability, registration, effect against third persons, or merely evidentiary convenience. Articles 1356–1358 of the Civil Code illustrate why the specific transaction must be examined.

Perjury and other consequences

An oath is legally serious. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, a person who knowingly and deliberately makes a material false statement under oath before an authorized officer, in a case required by law or made for a legal purpose, may be prosecuted for perjury.

The prescribed principal penalty is prision mayor in its minimum period—six years and one day to eight years—subject to the rules on criminal liability and sentencing. The amended law also provides a fine of up to ₱1,000,000 and perpetual absolute disqualification from holding an appointive or elective government position; it directs that the imprisonment penalty be imposed in its maximum period when the offender is a public officer or employee.

An incorrect statement is not automatically perjury. Criminal liability requires proof of all statutory elements, including materiality and a willful and deliberate falsehood. Depending on the conduct, forgery or fraudulent use of a notarized document may also raise separate civil, criminal, administrative, or disciplinary issues.

Evidence to preserve

Keep:

The complete original affidavit and all attachments.
A clear color scan of every page before submission.
Drafts showing how corrections were made.
The IDs presented and proof that they were current, subject to proper data security.
The notary’s name, office address, commission information, and receipt or payment record.
Emails or messages arranging the notarization.
Electronic-notarization transaction records and downloaded files.
Proof of the affiant’s physical location on the notarization date, if later disputed.
Source records supporting every material statement.
Submission receipts, stamped receiving copies, electronic acknowledgments, and courier records.
Communications showing coercion, unauthorized alterations, or instructions to sign an incomplete document.

Protect copies containing ID numbers, addresses, signatures, and other personal data. Share them only with the recipient, counsel, investigators, or officials who legitimately need them.

Common mistakes to avoid

Signing a paper affidavit before meeting the notary.
Sending someone else to “process” an absent affiant’s oath.
Relying only on a cedula.
Using an expired, unreadable, or mismatched ID without bringing supporting proof.
Leaving material blanks for someone to fill in later.
Allowing a secretary or fixer to perform the notarial act without the commissioned notary.
Failing to sign the notarial register.
Using an acknowledgment when a jurat is required.
Using a notary who is related to or financially interested in the transaction.
Altering pages or attachments after notarization.
Assuming notarization proves ownership, authority, truth, or legal validity.
Missing the filing deadline while trying to perfect the affidavit.
Treating an informal video call as lawful remote notarization.
Using a generic internet form without checking the receiving office’s current requirements.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A signature, thumbmark, seal, commission number, or notarial entry may be forged or fabricated.
The affiant never appeared before the notary.
A notarized document was signed under threat, coercion, deception, or incapacity.
The document transfers, mortgages, waives, settles, or encumbers land, inheritance rights, corporate interests, or a substantial claim.
A special power of attorney is being used to sell or encumber property.
A court, prosecutor, tax, registration, labor, immigration, or procurement deadline is near.
Someone has inserted pages, changed an amount, or replaced an attachment.
The supposed notarial act cannot be found in the notary’s records.
The affidavit contains a material mistake that has already been submitted.
A false affidavit has resulted in arrest, loss of property, freezing of funds, cancellation of rights, or another immediate injury.

For a suspicious paper notarization, the Office of the Clerk of Court for the court that commissioned the notary may be asked to verify the commission and relevant notarial records. Obtain legal advice before surrendering an original suspected forged document.

Frequently asked questions

Can I sign the affidavit before going to the notary?

Generally, no. An affidavit requiring a jurat must be signed in the notary’s presence. An instrument requiring only acknowledgment may have been signed earlier, but the signer must still appear and acknowledge the signature and voluntary execution.

Are two valid IDs always required?

No. The notarial rule generally requires at least one current official identification document bearing the holder’s photograph and signature. A notary or receiving office may require more where justified or under its own procedure.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity under the current notarial rule.

Are witnesses always required?

No. An ordinary affidavit does not automatically require subscribing witnesses. Witnesses may be required by a special law, prescribed form, identity-verification alternative, physical-signing accommodation, or the nature of the transaction.

Does every page need to be signed?

The notarial rules do not create one universal page-signing rule for every affidavit, but courts, agencies, contracts, and prescribed forms may require initials or signatures on every page. Follow the recipient’s instructions and use safeguards against page substitution.

Does notarization make every statement true?

No. It records the notarial act and supports due execution and authenticity. It does not establish the truth of every factual assertion.

Can an affidavit be notarized remotely?

Yes, if it is processed as an electronic document by a commissioned Electronic Notary Public through a Supreme Court-accredited facility and all electronic-notarization requirements are met. An ordinary call with a traditional notary is insufficient.

Does an affidavit expire?

There is no universal expiration period. The receiving institution may require a recent affidavit, and the affidavit should not be used if material facts have changed.

Can an affidavit be notarized without a lawyer drafting it?

A person may prepare a straightforward affidavit, but the notary’s role is not necessarily to give legal advice or confirm that the affidavit is strategically sufficient. Legal review is advisable where rights, property, liability, criminal accusations, or contested facts are involved.
