Quick answer

For a standard paper affidavit in the Philippines, the affiant should personally appear before a duly commissioned notary public, present a complete document and acceptable proof of identity, sign the affidavit in the notary's presence, and take an oath or affirmation that the statements in it are true. The notary must record the act in the notarial register, and the affiant must sign or place the appropriate mark in that register. These requirements come from the Supreme Court's 2004 Rules on Notarial Practice. (Supreme Court of the Philippines)

A valid current government-issued identification document bearing the affiant's photograph and signature is generally competent evidence of identity. A community tax certificate or cedula by itself is not sufficient. The Rules also provide a credible-witness procedure when the affiant cannot establish identity through the usual documentary method. (eLibrary)

An affidavit normally requires a jurat, commonly introduced by the words "SUBSCRIBED AND SWORN TO before me." A jurat is different from an acknowledgment. For a jurat, the affiant must sign in the notary's presence and actually take an oath or affirmation. (eLibrary)

Electronic notarization is now recognized under the Supreme Court's Rules on Electronic Notarization, but it is a separate system for electronic PDF or PDF/A documents using a Supreme Court-accredited Electronic Notarization Facility and a commissioned Electronic Notary Public. It does not mean that an ordinary paper affidavit may simply be notarized through Zoom, Messenger, or another video call. Traditional paper notarization remains governed by the 2004 Notarial Rules. (Supreme Court of the Philippines)

What makes a document an affidavit?

An affidavit is more than a written statement bearing someone's signature. Its defining feature is that the person making the statement—the affiant—makes it under oath or affirmation before an officer legally authorized to administer that oath.

For an ordinary notarized affidavit, this is accomplished through a jurat. Under the 2004 Notarial Rules, a jurat involves four essential acts: the affiant appears personally before the notary, is properly identified, signs the document in the notary's presence, and takes an oath or affirmation concerning the document. (eLibrary)

This is why merely attaching a notarial stamp to a statement that was signed elsewhere does not satisfy the requirements for a proper jurat.

Different laws, agencies, courts, and transactions may prescribe additional contents for particular affidavits. An Affidavit of Loss, Affidavit of Support, complaint-affidavit, judicial affidavit, affidavit required for land registration, and affidavit accompanying a government application may therefore have requirements beyond the general notarization rules.

Jurat versus acknowledgment

The distinction matters because the wrong notarial act can create problems.

Jurat	Acknowledgment
Commonly used for affidavits and sworn statements	Commonly used for contracts, deeds, powers of attorney, and similar instruments
The signer must sign in the notary's presence	The signer acknowledges that the signature was voluntarily affixed and the document is his or her free act and deed
The signer takes an oath or affirmation concerning the document	An oath about the truth of the document is not the defining requirement
Common wording includes "subscribed and sworn to before me"	Common wording includes "acknowledged before me"

The Supreme Court expressly defines a jurat as requiring signature in the notary's presence followed by an oath or affirmation. An acknowledgment, by contrast, centers on the signer's personal appearance, identity, voluntary execution, and, where applicable, authority to sign in a representative capacity. (eLibrary)

For a conventional affidavit, a jurat is ordinarily the appropriate notarial certificate.

Requirements for notarizing a paper affidavit

For the usual Philippine paper affidavit, the safest practical checklist is:

Prepare a complete affidavit. Do not leave material names, dates, amounts, factual allegations, annex references, or other essential portions blank. A notary may not notarize a blank or incomplete instrument. (eLibrary)
Do not sign the affidavit in advance if it requires a jurat. The Rules require the affiant to sign in the notary's presence. (eLibrary)
Appear personally before the notary public. For traditional paper notarization, sending the signed affidavit through another person is not a substitute for appearance. The Supreme Court has repeatedly disciplined notaries who notarized documents without the signatory personally appearing. (eLibrary)
Bring competent evidence of identity. At least one current identification document issued by an official agency and bearing the holder's photograph and signature can satisfy the rule, subject to the notary's duty to determine identity properly. (eLibrary)
Take the oath or affirmation. The notary should actually administer it. Notarization is not merely payment, stamping, and signing.
Sign the notarial register. The principal must sign or affix the appropriate thumb or other mark in the notary's register at the time of notarization. (eLibrary)
Keep the completed notarized copy. Check that the jurat and notarial details have been completed and that the document has the notary's signature and seal and the corresponding Doc. No., Page No., Book No., and Series entries.

Not every lawyer is automatically a notary public. Traditional notarial acts may be performed only by a lawyer holding a valid notarial commission, and the lawyer's authority is territorially limited by the commissioning court. (eLibrary)

What identification is acceptable?

The rule focuses on competent evidence of identity, not simply on possession of any card.

The Supreme Court's rules recognize at least one current identification document issued by an official agency bearing both the person's photograph and signature. The non-exclusive examples recognized in the rules and jurisprudence include passports, driver's licenses, PRC IDs, NBI and police clearances meeting the required characteristics, GSIS and SSS cards, PhilHealth cards, senior-citizen identification, government-office identification, and other qualifying government-issued documents. (eLibrary)

A cedula or community tax certificate alone is not competent evidence of identity because it does not meet the photograph-and-signature requirement. The Supreme Court has specifically rejected reliance on a CTC alone for this purpose. (eLibrary)

The Rules also provide an alternative based on credible witnesses. Depending on the circumstances, identity may be established through the oath or affirmation of a qualified credible witness personally known to the notary, or through two qualified credible witnesses who personally know the affiant and establish their own identities in the prescribed manner. The witnesses cannot be persons who are privy to the document or transaction. (eLibrary)

If the affiant is genuinely personally known to the notary, separate documentary identification may not be necessary. But "personally known" requires actual personal knowledge of the signatory's circumstances independent of representations made immediately before or during notarization; simply introducing oneself to the notary does not qualify. (eLibrary)

Personal appearance is not optional

Personal appearance is one of the most important safeguards in Philippine notarization.

For a traditional paper affidavit, the notary should not notarize a document merely because someone else brought it to the office together with a photocopy of the affiant's ID. Nor should an office assistant obtain the affiant's signature elsewhere and ask the lawyer to notarize it later.

The Supreme Court has repeatedly explained that physical appearance allows the notary to verify the signer's identity and signature and determine whether the document is being executed freely. (eLibrary)

Traditional notaries are also generally expected to perform notarial acts at their regular place of work or business, subject to limited exceptions under the Notarial Rules, and always within their territorial jurisdiction. (eLibrary)

The affidavit must be complete before notarization

Do not sign an affidavit containing blank spaces intended to be filled in later.

The 2004 Notarial Rules expressly prohibit a notary from notarizing a blank or incomplete instrument or document. They likewise prohibit affixing the notary's signature or seal to an incomplete notarial certificate. (eLibrary)

Before signing, review names, addresses, dates, amounts, property descriptions, identification details, attachments, numbered allegations, and any references to exhibits or annexes.

This is particularly important when the affidavit affects property, inheritance, employment, immigration, a criminal complaint, a pending case, corporate authority, or another person's legal rights.

What does notarization actually prove?

Notarization is legally significant, but its effect is sometimes misunderstood.

Proper notarization generally converts an otherwise private document into a public document and gives it evidentiary advantages concerning its authenticity and due execution. The Supreme Court has repeatedly emphasized that notarization is not an empty formality. (eLibrary)

But notarization does not automatically make everything written in the affidavit true, nor does it cure an illegal transaction, lack of authority, fraud, mistake, or another substantive defect. The Supreme Court has held that notarization strengthens the document's reliability as to authenticity and due execution but does not establish its intrinsic legal validity. (eLibrary)

A properly notarized affidavit therefore remains subject to challenge when its factual assertions, execution, authenticity, or underlying transaction are disputed.

Can the notary refuse to notarize an affidavit?

Yes.

A notary is performing a public function, not merely selling a signature and seal. The Notarial Rules require refusal in circumstances such as where the transaction appears unlawful or immoral, the signatory appears not to understand its consequences, or the notary concludes that the signatory is not acting voluntarily. The notary also cannot lawfully notarize a blank or incomplete document. (eLibrary)

A notary may consequently ask questions, examine supporting documents, require clearer identification, ask for proof of authority, request corrections, or decline the transaction altogether.

Electronic and remote notarization

The legal landscape changed significantly with A.M. No. 24-10-14-SC, the Rules on Electronic Notarization, approved by the Supreme Court in 2025.

The system covers electronic documents in PDF or PDF/A format and permits in-person electronic notarization, remote electronic notarization by videoconference, or a combination of the two. The transaction must use a Supreme Court-accredited Electronic Notarization Facility and must be handled by a separately commissioned Electronic Notary Public. (Supreme Court of the Philippines)

For an electronic affidavit requiring a jurat, the document must be electronically signed in the presence of the Electronic Notary Public. The Supreme Court's current FAQ specifically states that a jurat document should not be signed before it is uploaded for the electronic notarial transaction. (Supreme Court of the Philippines)

Electronic notarization does not abolish traditional notarization. Paper documents bearing handwritten or "wet" signatures continue to be governed by the 2004 Notarial Rules. Notarial wills and depositions are excluded from the electronic-notarization regime. (Supreme Court of the Philippines)

As of August 26, 2026, the Supreme Court's implementation portal states that applications for Electronic Notarial Commissions opened on August 10, 2026, while the public directory of commissioned Electronic Notaries Public and accredited facilities is still shown as "available soon." Anyone seeking electronic notarization should therefore check the Supreme Court portal for actual current service availability rather than assuming that any lawyer offering an ordinary video call can perform it. (Supreme Court of the Philippines)

Affidavits signed while abroad

Filipinos abroad may have affidavits notarized or subjected to a jurat before authorized Philippine consular officers, subject to the requirements of the particular embassy or consulate.

DFA foreign posts commonly require personal appearance, a valid passport or other prescribed identification, and an unsigned affidavit that is signed before the consular officer. Requirements, appointment systems, fees, and processing times vary by post. (Vientiane PE)

The Electronic Notarization Rules also contemplate remote electronic notarization for a principal outside the Philippines, but only under specific conditions. Among them, the Electronic Notary Public must be physically in the Philippines, while the principal abroad must be within the premises of a Philippine embassy, consular office, or office of a Philippine Honorary Consul, with confirmation by the designated foreign-post officer. (Supreme Court of the Philippines)

If a document is instead notarized by a foreign notary, check with the Philippine agency, court, bank, registry, or other recipient whether an apostille, authentication, translation, or other legalization requirement applies.

Does an affidavit expire?

The general Notarial Rules do not create a universal expiration period after which every affidavit automatically becomes invalid.

However, the purpose for which the affidavit is being submitted may impose its own time requirement. An agency might require a recently executed affidavit, a bidding document may apply only to a particular procurement, and an affidavit dealing with circumstances that later changed may cease to be useful or accurate.

The safer question is therefore not simply "How old is the affidavit?" but whether the receiving law, rule, agency, contract, or proceeding requires a particular execution date or whether the facts sworn to remain accurate.

Evidence to preserve after notarization

Keep the original or a high-quality copy of the completed affidavit, including every page, annex, jurat, seal, and notarial-detail page. Also retain information showing when and where it was notarized and, where relevant, proof relating to the identification or supporting documents used.

This can become important if someone later alleges that the affidavit was forged, altered after signing, notarized without personal appearance, or never entered in the notary's records.

Notarial-register records matter. The Supreme Court has explained that the absence of an allegedly notarized document from the corresponding notarial records can create serious doubt about whether proper notarization actually occurred. (eLibrary)

The Supreme Court also amended the 2004 Notarial Rules effective June 21, 2025 to strengthen digital reporting by traditional notaries. Among other changes, notaries must electronically transmit the prescribed monthly notarial records to the court clerk within the first 10 days of the following month. (Supreme Court of the Philippines)

Common mistakes to avoid

The most frequent problems are signing a jurat affidavit before reaching the notary, allowing another person to bring the affidavit for notarization, relying only on a cedula, leaving blanks for later completion, using the wrong notarial certificate, assuming that any lawyer can notarize documents anywhere, and treating an informal video call as valid remote notarization.

Another serious mistake is signing factual statements without carefully checking them. An affidavit is made under oath. Deliberately making a materially false statement under oath can carry legal consequences, including possible liability for perjury when the statutory elements are present.

Never sign an affidavit merely because someone says it is "just a requirement." Read every statement first.

When legal help is urgent

Seek legal advice before signing if the affidavit concerns a pending criminal complaint, admission of liability, ownership or transfer of land, inheritance rights, marital or parental status, immigration consequences, large financial obligations, corporate authority, waiver or release of claims, or facts that another party is likely to dispute.

Legal review is also advisable if someone asks you to sign an affidavit containing facts you did not personally observe, leave material portions blank, backdate the document, use another person's identification, state that you personally appeared when you did not, or sign a document whose legal effect you do not understand.

If a supposedly notarized affidavit bears your forged signature, was notarized without your appearance, or appears to contain fabricated notarial information, preserve the original document and related communications before taking further action.

FAQ

Can I sign my affidavit at home and have someone else bring it to the notary?

For an affidavit requiring a jurat, no. The affiant must personally appear and sign in the notary's presence. (eLibrary)

Is one valid ID enough?

The rule permits at least one current identification document issued by an official agency bearing the person's photograph and signature. A notary may nonetheless need additional information or documentation to resolve a genuine identity issue. (eLibrary)

Is a cedula enough?

No. Supreme Court jurisprudence specifically recognizes that a community tax certificate alone does not satisfy the competent-evidence-of-identity requirement because it lacks the required photograph and signature. (eLibrary)

Must every affidavit be notarized?

An affidavit, in the ordinary legal sense, is a statement made under oath or affirmation. If a particular statute, rule, form, or government procedure provides another authorized method of administering the oath, that specific rule should be followed. Do not assume that every declaration or certification has identical formal requirements.

Does notarization mean the notary guarantees that my statements are true?

No. The notary performs the required notarial act and certifies matters associated with that act. Notarization does not make false facts true or guarantee the intrinsic validity of the transaction described in the document. (eLibrary)

Can an affidavit be notarized online?

Electronic notarization is legally recognized, but only through the Supreme Court's regulated Electronic Notarization system using a commissioned Electronic Notary Public and an accredited Electronic Notarization Facility. Ordinary video conferencing is not a substitute. (Supreme Court of the Philippines)

Can a notary notarize an incomplete affidavit and let me fill in the details afterward?

No. The Notarial Rules prohibit notarization of blank or incomplete documents. (eLibrary)

Does a notarized affidavit automatically win a court case?

No. Notarization gives the document evidentiary significance concerning authenticity and due execution, but the statements and legal conclusions in the affidavit can still be disputed and tested against other evidence and applicable procedural rules. (eLibrary)
