Quick answer

In the Philippines, an affidavit is ordinarily a written statement of facts made under oath or affirmation. For a paper affidavit using a handwritten signature, the affiant must personally appear before a duly commissioned notary public, establish identity if not personally known to the notary, sign the affidavit in the notary's presence, and take an oath or affirmation concerning the document. These requirements form the jurat. (eLibrary)

Do not simply sign an affidavit at home and send it to someone else to have it notarized. A traditional notary cannot validly perform a jurat while the affiant is absent. Presenting the affiant's ID, passport, photocopy, video, or previously signed document does not substitute for the required personal appearance under the traditional rules. (eLibrary)

Electronic notarization is now separately allowed under the Supreme Court's Rules on Electronic Notarization, A.M. No. 24-10-14-SC. For qualifying electronic documents, an Electronic Notary Public may conduct an in-person or remote electronic notarization through a Supreme Court-accredited Electronic Notarization Facility. These rules supplement—not replace—the traditional rules for paper documents. (eLibrary)

What makes an affidavit an affidavit?

The important feature of an affidavit is not merely its title. It is the fact that the person making the statement—the affiant—swears or affirms to it before a person legally authorized to administer an oath.

Under the 2004 Rules on Notarial Practice, a jurat requires the affiant, on the same occasion, to appear personally before the notary, be personally known to the notary or properly identified, sign the document in the notary's presence, and take an oath or affirmation concerning the document. (eLibrary)

This is different from an acknowledgment. In an acknowledgment, the signer personally appears and declares that the signature was voluntarily affixed and that the instrument is the signer's free and voluntary act and deed. An acknowledgment may therefore be appropriate for instruments such as deeds, contracts, powers of attorney, and similar documents, depending on the document and governing law. A sworn affidavit, by contrast, ordinarily calls for a jurat. (eLibrary)

Using the wrong notarial certificate can matter, particularly when the document is required by a court, government agency, registry, bank, or another institution.

Requirements for a traditional paper affidavit

For the usual paper affidavit with a wet-ink signature, the safest procedure is straightforward:

Prepare a complete affidavit. State the affiant's identity and relevant circumstances and set out the facts accurately. Check whether the court, agency, prosecutor, employer, bank, school, or other recipient requires a particular form or wording.
Do not sign the jurat affidavit in advance. The affiant must sign it in the presence of the notary public. (eLibrary)
Appear personally before the notary. Sending the document through another person is not enough. (Lawphil)
Bring competent proof of identity. Unless personally known to the notary, the affiant must be identified through competent evidence of identity under the Rules.
Review the affidavit before taking the oath. Dates, names, amounts, addresses, descriptions of property, attachments, and other material facts should be checked carefully.
Take the oath or affirmation. The notary must actually administer the oath or affirmation; stamping and signing the document without this step does not satisfy the concept of a jurat.
Check the completed notarization. The document should contain the appropriate notarial certificate and the notary's required commission and professional details, together with its notarial register information where applicable.
Keep a complete copy. Preserve the final notarized affidavit, its attachments, and evidence showing where and when it was submitted.

The Supreme Court has repeatedly stressed that notarization is not a meaningless formality. Among other duties, the notary must record notarial acts in the official notarial register. (Lawphil)

What identification should you bring?

Under the 2004 Notarial Rules, as amended, competent evidence of identity generally includes at least one current identification document issued by an official agency bearing the person's photograph and signature, unless the person is personally known to the notary. Examples identified in the rules and jurisprudence include passports, driver's licenses, PRC IDs, SSS cards, and other qualifying government-issued identification. (Lawphil)

A community tax certificate or cedula alone is not competent evidence of identity for this purpose because it does not satisfy the required identification characteristics. The Supreme Court has expressly rejected reliance on a community tax certificate alone under the current notarial identification rules. (eLibrary)

If the affiant has no qualifying ID, the Rules contain an alternative procedure involving credible witnesses under specified conditions. Do not simply bring any friend or relative and assume that person can serve as an identifying witness; the requirements governing credible witnesses must actually be met. (eLibrary)

A particular notary may also reasonably ask for additional documentation where identity, capacity, authority, or the circumstances of the transaction require verification.

Personal appearance is not optional for traditional notarization

One of the most serious mistakes is treating notarization as a signature-and-stamp service.

For a traditional paper affidavit, the affiant must actually be before the notary. The Supreme Court has disciplined notaries for notarizing documents when signatories were absent, emphasizing that personal appearance allows the notary to verify identity, the genuineness of the signature, and the voluntary character of the act. (Lawphil)

Accordingly, these practices should not be treated as valid substitutes for personal appearance under the traditional rules:

leaving a signed affidavit with a secretary or messenger for later notarization;
giving another person your ID and asking that person to have your affidavit notarized;
emailing a signed paper affidavit to an ordinary notary and asking the notary to stamp a printed copy; or
using an ordinary video call with a traditional notary outside the electronic-notarization framework.

The temporary 2020 Interim Rules on Remote Notarization of Paper Documents have been repealed by the 2025 Rules on Electronic Notarization. Remote notarization now operates under the electronic-notarization regime and its prescribed technology and procedures. (eLibrary)

Can an affidavit now be notarized online?

Yes, but only through the system authorized by the Supreme Court.

A.M. No. 24-10-14-SC allows electronic notarization of electronic documents through a duly commissioned Electronic Notary Public (ENP) using an accredited Electronic Notarization Facility (ENF). Electronic notarization may be performed through In-Person Electronic Notarization (IEN) or Remote Electronic Notarization (REN). (Supreme Court of the Philippines)

The electronic rules generally apply to documents in PDF or PDF/A format. Paper documents bearing handwritten signatures remain governed by the traditional 2004 Notarial Rules. Notarial wills and depositions are excluded from the electronic-notarization regime. (eLibrary)

For an electronic affidavit requiring a jurat, the principal must affix the electronic signature through the ENF in full view of the ENP and then take the oath. A jurat document therefore should not simply be pre-signed and uploaded as though it were an acknowledgment. (eLibrary)

For remote electronic notarization, the ENF provides identity-verification, videoconferencing, geolocation, and other security functions. The parties must use the authorized facility; an ordinary Zoom, Messenger, FaceTime, or similar video call by itself is not the electronic-notarization process contemplated by the Rules. (eLibrary)

What if the affiant is outside the Philippines?

There are different possibilities depending on the document and the intended recipient.

Under the electronic-notarization rules, an ENP in the Philippines may perform a remote electronic notarial act for a principal abroad only under the Rules' limited extraterritorial procedure. At the time of notarization, the principal must be within the premises of a Philippine embassy, Philippine consular office, or office of a Philippine Honorary Consul, subject to the applicable requirements and local restrictions. (Supreme Court of the Philippines)

For conventional documents executed abroad, notarization before a foreign notary or execution before a Philippine consular officer may be possible depending on the circumstances and the receiving institution. A document notarized abroad may also require an apostille, authentication, or another form of legalization, depending on the country of execution, applicable treaty arrangements, and the purpose for which the document will be used in the Philippines.

Because requirements vary substantially for overseas documents, check the particular court, agency, Registry of Deeds, bank, embassy, or other recipient before executing the affidavit.

Does every document need notarization?

No.

A private contract is not automatically invalid merely because it is unnotarized, unless a particular law requires a specified form for validity, enforceability, registration, or another legal effect. The applicable rule depends on the type of transaction.

An affidavit is different because its sworn character is fundamental to the document. If a law, rule, court, or government agency requires an affidavit, verification, sworn declaration, complaint-affidavit, counter-affidavit, or similar sworn instrument, the required oath must be properly administered by an authorized officer.

This does not necessarily mean that the officer must always be a private notary public. Certain judges, prosecutors, consular officers, administrative officials, and other officers may have statutory or rule-based authority to administer oaths for particular proceedings.

Notarization does not prove that every statement is true

A notary is not deciding whether the factual allegations in the affidavit are ultimately correct. Proper notarization establishes that the prescribed notarial act occurred—including identity and oath requirements—but it does not make false facts true or prevent another party from contesting the affidavit.

An affiant should therefore never sign an affidavit merely because someone else prepared it, especially if the document contains statements outside the affiant's personal knowledge or language the affiant does not understand.

Knowingly making a materially false statement under oath may expose a person to perjury where the statutory elements are present. Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, penalizes knowingly making an untruthful statement under oath or in an affidavit upon a material matter before a competent person authorized to administer the oath when the legal requirements for perjury are met. (eLibrary)

If the affidavit will be filed in court

Do not assume that an ordinary affidavit automatically qualifies as a Judicial Affidavit.

The Judicial Affidavit Rule, A.M. No. 12-8-8-SC, contains additional requirements regarding the witness's questions and answers, the language used, documentary or object exhibits, the witness's awareness of the consequences of giving evidence under oath, and the lawyer's attestation. It also contains filing requirements and consequences for non-compliance. (Lawphil)

Court pleadings may likewise require a specific verification, certification against forum shopping, or other sworn certification under the applicable Rules of Court. A generic affidavit should not be substituted for a required procedural document without checking the governing rule.

Deadlines are especially important. Correct notarization will not cure a document that was filed after a jurisdictional or mandatory deadline.

Common mistakes to avoid

Signing before meeting the notary. For a traditional jurat, the signature must be made in the notary's presence. The Supreme Court has specifically enforced this requirement. (Lawphil)

Using only a cedula as identification. A community tax certificate alone does not satisfy the present competent-evidence-of-identity requirement. (eLibrary)

Not appearing personally. Giving your ID and signed affidavit to another person does not permit a traditional notary to notarize it lawfully.

Confusing a jurat with an acknowledgment. An affidavit normally requires the affiant to swear to or affirm the document, not merely acknowledge an existing signature.

Leaving material blanks. Complete names, dates, amounts, factual statements, exhibit references, and other material information before executing the document. Never allow material facts to be inserted after you have sworn to a different version.

Assuming notarization cures a defective document. Notarization cannot make an illegal transaction lawful, create authority that the signer does not possess, or satisfy separate statutory requirements that have not been met. A notary must refuse a notarial act when the notary knows or has good reason to believe the act or transaction is unlawful or immoral. (Lawphil)

Using an uncommissioned or improperly commissioned notary. Not every lawyer is automatically authorized to notarize documents. A lawyer must hold a valid notarial commission for the relevant traditional jurisdiction, while electronic notarization requires a separate electronic notarial commission. (eLibrary)

Evidence worth preserving

Keep the exact final version of the affidavit that was notarized, including every page and attachment. If it was electronically notarized, retain the final electronically notarized file rather than relying only on a printed copy.

Also preserve correspondence showing why the affidavit was prepared, supporting documents referred to in it, proof of submission or filing, electronic filing receipts, courier records, and any acknowledgment issued by the receiving court or agency.

If the authenticity of a notarization later becomes disputed, details such as the notarial date, notarial register entry, document number, page number, book number, series, notary's name, commission details, and location of notarization can become important.

The Supreme Court amended the traditional notarial rules in 2025 to strengthen digital preservation and reporting of notarial records. Among other changes, commissioned notaries have updated requirements concerning electronic copies of monthly notarial entries and specified notarized instruments. Those amendments became effective on June 21, 2025. (Supreme Court of the Philippines)

When legal help is urgent

Seek legal advice promptly if an affidavit concerns an approaching court, prosecutor, administrative, tax, immigration, labor, election, or regulatory deadline; if you are being asked to admit liability or waive rights; if the affidavit concerns criminal accusations; if someone asks you to swear to facts you do not personally know to be true; or if you discover that a document supposedly bearing your notarized signature was executed without your participation.

Immediate review is also advisable when a disputed affidavit has already been submitted to a court or government agency, when there is suspected forgery or fraudulent notarization, or when the receiving institution has rejected a document because of defective notarization. The appropriate remedy depends on what document was executed, how it was notarized, where it was filed, and what legal consequence has already followed.

FAQ

Can I sign my affidavit before going to the notary?

For a traditional paper affidavit requiring a jurat, no. The 2004 Notarial Rules require the affiant to sign the document in the notary's presence. (eLibrary)

Can someone else take my signed affidavit and ID to the notary?

Not for a valid traditional jurat. Your personal appearance is required.

Is a cedula enough for notarization?

A community tax certificate alone is not competent evidence of identity under the current notarial rules. Bring a qualifying current government-issued identification document bearing the required identifying features. (eLibrary)

Do I need two valid IDs?

The Supreme Court rule does not impose a universal two-ID requirement. It refers to at least one qualifying current identification document when the person is not personally known to the notary. A notary or receiving institution may nevertheless request additional identification where appropriate. (Lawphil)

Can an affidavit be notarized through video call?

A traditional notary cannot simply replace required personal appearance with an ordinary video call. Remote electronic notarization is permitted only under the Supreme Court's electronic-notarization framework using an accredited ENF and a commissioned ENP. (Supreme Court of the Philippines)

Can I electronically notarize a PDF affidavit?

Potentially, yes. Electronic documents in PDF or PDF/A format may fall within the Rules on Electronic Notarization. For a jurat, however, the affiant must electronically sign through the ENF in the ENP's presence and take the oath. (eLibrary)

Is an affidavit automatically accepted because it is notarized?

No. The receiving court or agency may impose additional requirements concerning contents, form, attachments, filing method, authority of the affiant, deadlines, or a prescribed affidavit template. Proper notarization does not cure defects unrelated to notarization.

Can the notary change statements in my affidavit?

The affidavit should accurately reflect what you are swearing to. Material changes should be reviewed and incorporated before you execute and swear to the final version. Never permit material information to be added to an already executed affidavit without proper re-execution where required.

What if the notary personally knows me?

The Rules recognize personal knowledge as an alternative to identification through competent evidence of identity. In practice, a notary may still request identification as a safeguard or to comply with recordkeeping requirements applicable to the circumstances. (eLibrary)
