Quick answer

An affidavit is a written statement of facts voluntarily made under oath. For a paper affidavit to be properly notarized in the Philippines, the affiant must generally:

use a complete and truthful affidavit;
personally appear before a duly commissioned notary public;
present competent evidence of identity;
sign the affidavit in the notary’s presence;
swear or affirm that its contents are true; and
complete the notary’s register entry and other required formalities.

For an affidavit, the proper notarial certificate is ordinarily a jurat, usually beginning with “Subscribed and sworn to before me.” An acknowledgment, which merely confirms that a person executed a document as a voluntary act, is generally not a substitute for administering the oath required for an affidavit.

Notarization does not automatically prove that every allegation is true. It establishes the formal circumstances of execution and oath. The affiant remains responsible for the truthfulness of the statements and may face perjury or other liability for a deliberate material falsehood.

What an affidavit should contain

Requirements vary according to the affidavit’s purpose and the rules of the office, court, or agency receiving it. A basic affidavit commonly contains:

A title identifying its purpose, such as “Affidavit of Loss” or “Complaint-Affidavit”
The affiant’s full legal name and relevant personal circumstances
A statement that the affiant is of legal age or otherwise competent to execute the affidavit
The affiant’s address and, when relevant, citizenship, civil status, or occupation
Numbered paragraphs stating facts in chronological and understandable order
An explanation of how the affiant personally knows each material fact
Identification of supporting documents, photographs, messages, receipts, or other attachments
The specific purpose for which the affidavit is being executed
The affiant’s signature over the printed name
A properly completed jurat

An affidavit should state facts, not merely conclusions. For example, instead of saying that someone “committed fraud,” the affiant should describe what was represented, when and where it was said, why it was false, what the affiant relied upon, what was paid or delivered, and what happened afterward.

If a statement is based on information received from another person rather than the affiant’s own observation, that limitation should be made clear. An affidavit should never make secondhand information appear to be personal knowledge.

The difference between a jurat and an acknowledgment

The distinction matters because they serve different purposes.

Jurat

In a jurat, the person:

personally appears before the notary;
signs the document in the notary’s presence; and
swears or affirms that the statements are true.

This is the notarial act normally used for affidavits, verifications, and other sworn statements. The Supreme Court has explained that an affiant executing a jurat must sign in the authorized officer’s presence and take the oath before that officer. See Gamido v. New Bilibid Prisons Officials, G.R. No. 114829, March 1, 1995.

Acknowledgment

In an acknowledgment, the person personally appears and confirms that:

the signature on the document is the person’s own; and
the document was executed as the person’s free and voluntary act.

The document may generally have been signed before the appearance, provided the person personally acknowledges the signature and execution before the notary. Acknowledgments are commonly used for contracts, deeds, and powers of attorney.

Because an affidavit must be sworn to, a certificate containing only an acknowledgment may fail to establish that the affiant actually took an oath. The correct certificate should be determined from the nature of the document, not merely from the heading placed on it.

Personal appearance is mandatory for traditional notarization

For a paper document under the traditional notarial rules, the affiant must be physically present before the notary at the time of notarization. Sending a signed affidavit through a relative, employee, messenger, or courier is not sufficient.

The notary should not:

notarize an affidavit based only on a photocopy or scanned copy;
rely on a video call outside the authorized electronic-notarization system;
notarize a blank or incomplete document;
allow another person to sign for the affiant without lawful authority and the proper form of instrument;
certify that an affiant appeared on a date when the person was not present; or
notarize outside the notary’s authorized territorial jurisdiction.

The Supreme Court consistently treats personal appearance as a substantive safeguard, not a technical inconvenience. It enables the notary to verify identity, observe whether the person understands the document, and determine whether the execution appears voluntary. The governing traditional rules are the 2004 Rules on Notarial Practice, as amended.

What identification is acceptable?

Under the amended rule on competent evidence of identity, an affiant who is not personally known to the notary should present at least one current identification document issued by an official agency and bearing the affiant’s photograph and signature.

Examples listed in the rule include a current:

Passport
Driver’s license
Professional Regulation Commission ID
SSS or GSIS card
PhilHealth card
Senior citizen ID
Government office ID
Alien Certificate of Registration
Seaman’s book
NBI or police clearance bearing the required identifying features
Other official identification satisfying the rule

The governing definition appears in the Supreme Court’s 2008 amendment to the 2004 Rules on Notarial Practice.

A community tax certificate or cedula, standing alone, is ordinarily insufficient because it does not contain both a photograph and signature. Likewise, a company ID is not necessarily competent evidence of identity merely because it bears a photograph. The safest practice is to bring an unexpired government-issued ID containing both photograph and signature.

If the affiant has no qualifying ID, the rules provide a limited alternative involving credible witnesses who personally know the affiant and satisfy the rule’s identification and disinterest requirements. This should be arranged with the notary beforehand. It is not enough to bring any friend, relative, or coworker and ask that person to “confirm” the affiant’s identity.

Agencies and notaries may reasonably request additional identification where names, signatures, or personal details are inconsistent.

What happens during notarization?

For an ordinary paper affidavit, the process should generally proceed as follows:

The notary examines the complete document. Blank spaces, missing pages, inconsistent names, and absent attachments should be corrected before signing.
The notary verifies identity. The original qualifying ID should be shown. The notary records the required identifying information.
The notary checks understanding and voluntariness. A notary must refuse if the affiant does not appear to understand the document or is being forced to sign.
The affiant signs in the notary’s presence. For a jurat, do not sign in advance unless the notary specifically directs a lawful procedure consistent with the applicable rules.
The affiant takes an oath or affirmation. The affiant formally declares that the contents are true.
The affiant signs the notarial register. The notary records the transaction and any other information required by the notarial rules.
The notary completes the jurat. This includes the place and date, identifying details, commission information, signature, seal, and document, page, book, and series numbers.

A rubber stamp and seal alone do not make a document properly notarized. An incomplete certificate, missing register entry, false appearance date, or notarization by a person without a valid commission can seriously undermine the document.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, allow qualifying electronic documents to be notarized through:

In-person electronic notarization, where the principal physically appears before a commissioned electronic notary public; or
Remote electronic notarization, where the principal appears through the secure videoconferencing functions of an accredited electronic-notarization facility.

These rules cover electronic documents in the prescribed PDF or PDF/A format. The process must be conducted by a separately commissioned Electronic Notary Public through a Supreme Court-accredited facility. An ordinary video call, emailed scan, pasted image of a signature, or privately recorded online meeting does not by itself satisfy the Rules on Electronic Notarization.

Paper documents bearing handwritten signatures remain governed by the traditional notarial rules. Notarial wills and depositions are also subject to their applicable special rules rather than being converted automatically into remotely notarizable documents.

Before paying for remote notarization, verify the electronic notary and available facility through the Supreme Court’s official eNotarization portal. Availability may depend on current accreditation, system implementation, and the type of document involved.

Does every affidavit have to be notarized?

An affidavit, by definition, is ordinarily sworn before a person authorized to administer oaths. If a document is not sworn, it may be treated merely as an unsworn written statement even if its title says “Affidavit.”

However, not every declaration submitted to a government office must take the form of a notarized affidavit. Some laws and agency procedures accept:

verified forms;
certifications under a special rule;
unsworn declarations in a prescribed format;
electronic submissions with a legally recognized authentication method; or
declarations administered by an authorized public officer instead of a notary.

Always check the exact form and instructions of the receiving court, agency, bank, school, insurer, employer, or private institution. Notarizing the wrong form does not cure missing substantive requirements.

Special rules for judicial affidavits

A judicial affidavit is not merely an ordinary narrative affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it must generally contain:

the witness’s identifying and occupational information;
the examining lawyer’s name and address and the place of examination;
a statement that the witness is answering under oath and understands the possible liability for false testimony or perjury;
consecutively numbered questions and answers;
facts showing how the witness acquired personal knowledge;
identification and authentication of attached evidence;
the witness’s signature;
a jurat; and
the examining lawyer’s sworn attestation that the questions and answers were faithfully recorded and that the witness was not coached.

Judicial affidavits and exhibits are generally filed and served no later than five days before the applicable pre-trial, preliminary conference, or scheduled hearing, subject to the Rule and any controlling court order. A noncompliant or late judicial affidavit may be excluded, although the Rule allows limited relief under specified conditions.

The witness must still appear when required for cross-examination. Notarization alone does not eliminate the adverse party’s right to challenge the testimony.

Notarization does not prove that the contents are true

A notary ordinarily certifies the affiant’s appearance, identity, signature, oath, and the formal notarial act. The notary does not become a guarantor that every factual allegation is accurate.

The Supreme Court has recognized that the truth or falsity of an affidavit’s contents is principally the affiant’s responsibility, absent proof that the notary knowingly participated in wrongdoing. See Ick v. Amazona, A.C. No. 12375, February 26, 2020.

Similarly, a notarized affidavit is not automatically conclusive evidence in a contested case. Rules on relevance, authentication, personal knowledge, hearsay, admissibility, and cross-examination may still apply. Courts evaluate the affidavit together with testimony, documents, and the entire record.

False statements and perjury

A person should never sign an affidavit containing a fact that the person knows is false. A deliberate material falsehood made under oath before a competent officer, in a situation where the oath is required by law or made for a legal purpose, may constitute perjury under Article 183 of the Revised Penal Code.

Republic Act No. 11594 increased the penalties for perjury and also provides a higher penalty where the offender is a public officer or employee and the false assertion concerns the performance of official duties. The current statutory text is available in Republic Act No. 11594.

A mistake, uncertainty, estimate, or disputed recollection is not automatically perjury. Criminal liability depends on proof of all legal elements, including a knowingly false material assertion. Nevertheless, an affiant should correct inaccuracies before signing and clearly qualify matters that are based only on recollection, information, or belief.

Practical checklist before visiting a notary

Bring or prepare:

The complete, unaltered affidavit
All pages and referenced attachments
At least one current government-issued ID bearing your photograph and signature
Additional ID if your name or signature differs across records
The original documents supporting the affidavit, when available
Proof of any name change, such as a marriage certificate or court order
The receiving office’s prescribed form and instructions
Enough copies for filing, service, and your records
Any witness required by the underlying transaction

Before leaving, check that:

every factual paragraph is accurate;
all attachments are correctly labeled;
no material blank remains;
the venue and notarization date are correct;
the jurat is complete;
the notary’s commission details and seal appear;
document, page, book, and series numbers are stated; and
you received a complete copy exactly matching the notarized original.

Evidence to preserve

Keep:

A complete copy of the notarized affidavit
Copies or photographs of every attachment
The filing receipt, docket number, email acknowledgment, or courier proof
The name and office address of the notary
The date, time, and place of notarization
Receipts for notarial and filing fees
The original electronic file and transaction record for electronic notarization
Messages or instructions from the receiving office
Original supporting records, including receipts, contracts, screenshots, and correspondence

For screenshots and electronic messages, preserve the complete conversation, account details, dates, URLs, and original device data where possible. Cropped images may omit context needed to establish authenticity.

Common mistakes to avoid

Signing a jurat before appearing before the notary
Asking a messenger to have an already signed affidavit notarized
Using an expired or nonqualifying ID
Leaving blanks to be filled after notarization
Attaching documents only after the affidavit has been notarized
Stating legal conclusions without describing the underlying facts
Claiming personal knowledge of events learned from someone else
Using inconsistent names, dates, amounts, or addresses
Treating an acknowledgment as equivalent to a jurat
Assuming notarization makes inadmissible evidence automatically admissible
Using a generic affidavit when the receiving office requires a prescribed form
Missing a filing deadline while trying to perfect the affidavit
Paying for supposed “online notarization” conducted outside an authorized system
Altering, replacing, or removing a page after notarization

If a material correction is necessary after notarization, the safer course is usually to prepare and notarize a corrected or supplemental affidavit rather than erase, overwrite, or substitute text in the existing document.

When legal help is urgent

Consult a lawyer promptly if:

the affidavit will be used in a criminal, administrative, labor, tax, immigration, land, family, or election proceeding;
you have received a subpoena, summons, demand, or deadline-bearing order;
the affidavit contains an admission that could expose you to criminal or civil liability;
another person prepared the affidavit and is pressuring you to sign it immediately;
you are being asked to sign facts you did not personally witness;
the document involves a waiver, settlement, quitclaim, transfer of property, or authority over substantial assets;
your signature was forged or a document was notarized without your appearance;
the notary’s commission, identity, or register entry appears doubtful;
a material error is discovered after filing; or
the affiant is abroad, incapacitated, unable to read, or unable to sign in the usual manner.

Do not ignore a filing deadline merely because an affidavit has defects. Obtain immediate advice on whether a corrected affidavit, motion, explanation, or alternative submission is allowed.

Frequently asked questions

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

For a jurat, the affiant should sign in the notary’s presence and take the oath there. If it has already been signed, the notary may require a fresh copy to be signed properly.

Can another person bring my affidavit for notarization?

Not for traditional notarization. The affiant’s personal appearance is required. A representative cannot take the oath for the affiant.

Is one valid government ID enough?

The rule generally permits at least one current official identification document bearing the affiant’s photograph and signature. A notary may reasonably request another ID where identity cannot be established confidently or the records are inconsistent.

Is a cedula sufficient?

A cedula alone ordinarily does not meet the current competent-evidence requirement because it lacks both a photograph and signature. Bring a qualifying government-issued ID.

Can a notary refuse to notarize my affidavit?

Yes. A notary must refuse where the affiant is absent, cannot be properly identified, appears not to understand the document, is acting under duress, or presents an incomplete, unlawful, false, or otherwise prohibited transaction.

Can I use an affidavit notarized in another city?

Generally, yes, if it was lawfully notarized by a duly commissioned notary acting within the notary’s territorial authority. The receiving institution may nevertheless impose document-specific or recency requirements.

Does a notarized affidavit expire?

Notarization does not create a universal expiration date. However, the facts may become outdated, and the receiving office may require an affidavit executed within a specified period. Check the applicable instructions.

Can an affidavit be in Filipino or another language?

It should be in a language the affiant understands. If it will be submitted to a court or agency, a Filipino or English translation may be required. A judicial affidavit not in English or Filipino must be accompanied by a translation into English or Filipino.

Can I notarize an affidavit entirely online?

Only through a process compliant with the Supreme Court’s Rules on Electronic Notarization, using a commissioned Electronic Notary Public and an accredited facility. A casual video call followed by emailing a scanned signature is not enough.

What should I do if a document was notarized without my appearance?

Secure a certified or complete copy, preserve signature samples and proof of your whereabouts, and verify the notary’s commission and register entry. Consult counsel promptly regarding possible court remedies, criminal complaints, or an administrative complaint against the notary.
