Quick answer

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

bring a complete, accurate affidavit;
personally appear before a duly commissioned notary public;
prove identity through competent evidence of identity, unless personally known to the notary;
sign the affidavit in the notary’s presence; and
take an oath or affirmation that the statements are true.

A signature made at home and later delivered by another person ordinarily cannot support a valid traditional jurat. A community tax certificate or cedula alone is not competent evidence of identity under the current rules.

Notarization verifies the act of signing, identity, and oath. It does not prove that every statement in the affidavit is true, cure false or incomplete facts, or guarantee that the receiving court or agency will accept the document.

What an affidavit should contain

Requirements vary according to the affidavit’s purpose, but a sound affidavit normally contains:

A proper title. Examples include “Affidavit of Loss,” “Affidavit of Discrepancy,” or “Affidavit of Two Disinterested Persons.”
The affiant’s identifying information. This commonly includes the affiant’s full legal name, age or a statement that the person is of legal age, citizenship, civil status when relevant, and complete address.
A clear statement that the affiant is under oath.
Numbered factual statements. State events in chronological order and identify important dates, places, people, documents, amounts, and circumstances. Distinguish facts personally known to the affiant from information obtained elsewhere.
The affidavit’s purpose. Explain briefly why it is being executed and where it will be submitted, if known.
Relevant attachments. Refer to each attachment accurately and label it consistently. Never claim that a document is attached when it is not.
The affiant’s signature over the printed name. For a traditional jurat, do not sign until instructed by the notary because the signature must be made in the notary’s presence.
A complete jurat. The notary completes this portion after administering the oath. It ordinarily identifies the place and date of notarization, the affiant, the evidence of identity used, and the notary’s commission and register details.

An agency-prescribed form should be followed exactly. An affidavit drafted for one purpose may be legally or factually inadequate for another.

Jurat versus acknowledgment

Most affidavits require a jurat, not merely an acknowledgment.

For a jurat, the affiant appears before the notary, is properly identified, signs in the notary’s presence, and swears or affirms that the document is true. The Supreme Court’s definition of a jurat expressly includes all four requirements. Supreme Court decision applying the jurat requirements

An acknowledgment is different. The person represents that they signed the document voluntarily as their free act and deed. It is commonly used for contracts, deeds, and similar instruments. Signing may have occurred earlier, although personal appearance and proper identification at the acknowledgment remain necessary.

Changing the heading from “Acknowledgment” to “Jurat,” or vice versa, does not by itself make the notarial act correct. The certificate must match what the law or transaction requires and what actually happened before the notary.

Personal appearance is mandatory

For traditional notarization, the affiant must be physically present before the notary at the time of the notarial act. The notary cannot properly notarize an affidavit based only on:

a telephone call;
an ordinary video call;
an emailed scan;
a signature specimen;
another person’s assurance that the signature is genuine; or
an affidavit left with a secretary, liaison, fixer, or messenger.

The Supreme Court repeatedly treats personal appearance as an essential safeguard against forgery and unauthorized notarization. Supreme Court discussion of personal appearance and identification

A person should not be asked to sign a blank notarial register or a register entry that does not accurately identify the document and transaction.

Acceptable proof of identity

Unless the affiant is personally known to the notary, the affiant must present competent evidence of identity. Under the amended 2004 Rules on Notarial Practice, this generally means at least one current identification document issued by an official agency and bearing both the person’s photograph and signature.

Examples recognized by the rules include a current:

passport;
driver’s license;
Professional Regulation Commission ID;
SSS or GSIS card;
PhilHealth card;
voter’s ID;
senior citizen ID;
government-office ID;
seaman’s book or specified OFW identification; or
other qualifying official identification bearing the holder’s photograph and signature.

The list is not necessarily exclusive, but the document must satisfy the rule’s essential features. A receiving office or cautious notary may reasonably request additional identification, particularly where names, signatures, photographs, or personal details do not match.

A community tax certificate is no longer sufficient by itself. The Supreme Court has expressly reiterated this point. Supreme Court ruling on competent evidence of identity

If the affiant lacks qualifying identification, the rules provide a credible-witness method:

one credible witness who is personally known to the notary, personally knows the affiant, and is not a party to or interested in the transaction; or
two credible witnesses who personally know the affiant, are not parties to or interested in the transaction, and themselves present documentary identification.

This is not a shortcut that allows an unidentified companion or interested relative to “vouch” casually for the affiant. Confirm the arrangement with the notary before the appointment.

Name discrepancies and representatives

The affidavit and identification should use the affiant’s correct legal name. If an ID contains a married name, former name, spelling variation, missing middle name, or other discrepancy, bring documents explaining the difference, such as an applicable civil-registry certificate, court order, or other official record.

When a person signs for a corporation, partnership, estate, or another individual, the notary may require proof of authority, such as a board resolution, secretary’s certificate, special power of attorney, court appointment, or constitutive document. Notarization does not create authority that the signer does not legally possess.

Documents a notary should refuse

A notary should not proceed when, among other circumstances:

the affiant is absent;
identity has not been properly established;
the affidavit is blank or materially incomplete;
the notarial certificate is incomplete;
the notary knows or has good reason to believe the transaction is unlawful;
the affiant appears not to understand the act or is acting under duress;
the affiant cannot communicate directly with the notary and no lawful accommodation is available;
the notary has a prohibited interest in the transaction; or
the notary is disqualified because of the relationship specified in the rules.

Under the 2004 Rules, a notary is disqualified if the notary is the principal’s spouse, common-law partner, ancestor, descendant, or relative within the fourth civil degree by consanguinity or affinity. Supreme Court decision discussing the disqualification rule

Refusal is appropriate where a material fact, identity, authority, or legal requirement cannot be responsibly verified. A notary is not required to accept every document presented for notarization.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, recognize in-person and remote electronic notarization of qualifying electronic documents. Traditional paper notarization remains legally recognized.

Electronic notarization is not accomplished by merely emailing a PDF, pasting an image of a signature, or joining an ordinary video call. It must be performed by a properly commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility, using the prescribed identity-verification, electronic-signature, audiovisual, certificate, and recordkeeping procedures.

The electronic rules do not cover paper documents bearing wet signatures, notarial wills, or deposition taking. For an electronic jurat, the affiant must electronically sign through the facility in the Electronic Notary Public’s view and take the required oath or affirmation.

A principal abroad cannot simply connect from any overseas location. Limited extraterritorial electronic notarization is subject to special conditions, including presence within a Philippine embassy, consular office, or office of a Philippine honorary consul at the time of the act. Check the Supreme Court’s official electronic-notarization portal and FAQs for accredited facilities, participating notaries, and current operating instructions.

For a paper affidavit executed abroad, the practical routes usually involve a Philippine embassy or consulate, or notarization under the law of the foreign country followed by the authentication or apostille required for use in the Philippines. The destination agency should confirm what it will accept before execution.

Does every affidavit need notarization?

An affidavit is, by nature, a statement under oath. Where an office requests an “affidavit,” it ordinarily expects a valid jurat or another oath administered by an officer legally authorized to administer oaths.

However, not every written declaration or certification must be notarized. Some laws and government forms permit an unsworn declaration, certification, verification, or electronic submission. Conversely, some transactions require a public instrument or a particular sworn form as a condition of validity, registration, evidence, or processing.

Follow the exact law, court rule, checklist, or prescribed form governing the transaction. Notarizing a document unnecessarily does not improve defective content, while failing to notarize a document that must be under oath can result in rejection or loss of legal effect.

Validity, expiration, and filing deadlines

There is no universal expiration period for affidavits and no single nationwide deadline for submitting them. The relevant questions are:

Does the affidavit accurately describe facts as of the date it was signed?
Does the receiving office require a recently executed affidavit?
Has a relevant fact changed?
Does a statute, court rule, order, contract, or agency checklist impose a filing period?

A previously accurate affidavit can become unsuitable when circumstances change. Affidavits of loss, support, residency, income, status, or non-pending cases are particularly dependent on current facts.

Court deadlines can be strict. Under the Judicial Affidavit Rule, for example, parties generally file and serve judicial affidavits and attached evidence no later than five days before the applicable pre-trial, preliminary conference, or scheduled hearing for motions and incidents, subject to the Rule’s scope and exceptions. Criminal cases have additional provisions. Judicial Affidavit Rule, A.M. No. 12-8-8-SC

Do not assume that obtaining notarization extends a filing deadline. The affidavit must still reach the correct office through an accepted channel on time.

Practical checklist

Before going to the notary:

Obtain the latest form or checklist from the receiving court, agency, bank, school, employer, insurer, or registry.
Verify every name, date, address, number, and description against original records.
Remove unresolved blanks. Use “not applicable” only when truthful and permitted.
Assemble all referenced attachments in the correct order.
Bring the original qualifying ID and, if requested, photocopies.
Bring proof of authority if signing in a representative capacity.
Ask whether witnesses, additional IDs, photographs, thumbmarks, or special forms are required.
Do not sign a traditional affidavit in advance unless the notary confirms that the document requires an acknowledgment rather than a jurat.

During notarization:

Appear personally and deal with the commissioned notary.
Review the final document before signing.
Answer identity, capacity, and voluntariness questions truthfully.
Sign only when instructed.
Take the oath or affirmation.
Check that the notarial certificate is complete and that no material blanks remain.
Request an official receipt when applicable and retain the notary’s identifying details.

After notarization:

Scan or photograph the complete affidavit, attachments, and notarial certificate.
Preserve the receipt and proof of submission.
Submit through the channel required by the receiving office.
Keep the original safely; some offices retain it permanently.
Record the submission date, recipient, reference number, and deadline.

Evidence to preserve

Keep records that can establish both the truth of the affidavit and the regularity of its execution:

the final signed and notarized affidavit;
drafts showing corrections, where a dispute is foreseeable;
IDs used for notarization;
source records supporting each material statement;
original attachments;
the notary’s name, office address, commission details, and receipt;
appointment or electronic-session confirmation;
courier receipt, email acknowledgment, portal confirmation, or receiving copy; and
communications from the office explaining its requirements.

For an affidavit of loss, preserve evidence of ownership, the last known possession, efforts to locate the item, reports to the issuer or authorities, and requests to block or replace the lost credential or instrument.

Common mistakes

Avoid these frequent problems:

signing before appearing for a jurat;
sending a relative or employee to “have it notarized”;
using only a cedula as identification;
copying an online template without checking the receiving office’s form;
leaving dates, names, attachment references, or notarial details blank;
stating legal conclusions instead of the underlying facts;
swearing to facts outside the affiant’s personal knowledge without qualification;
altering the affidavit after notarization;
attaching documents that were not presented or accurately identified;
using inconsistent names across the affidavit, ID, and supporting records;
assuming notarization makes an unlawful or unauthorized transaction valid;
using a fake notary, expired commission, rubber-stamped certificate, or ordinary online video call; and
missing the filing deadline after completing notarization.

Never backdate an affidavit or ask a notary to certify an appearance that did not occur. False sworn statements may expose the affiant to criminal, civil, administrative, or procedural consequences depending on the facts and the law involved.

If notarization is defective

Defective notarization can strip a document of its character as a public document and leave it to be treated as a private document for evidentiary purposes. The effect on the underlying transaction depends on whether notarization or a public instrument was required merely for convenience, for admissibility or registration, or as an essential legal form. In some transactions—such as particular donations of immovable property—a failure to comply with the required public form can affect validity itself. Supreme Court discussion of defective notarization and public-document status

Do not alter the completed notarial certificate yourself. If the error is discovered promptly, contact the notary and the receiving office. Depending on the defect, a fresh affidavit and new notarization may be safer than an informal correction.

If a document appears to have been notarized without your presence, signature, or authority, preserve the original and obtain a certified copy or certification of the relevant notarial-register entry from the proper Office of the Clerk of Court. Do not write on or surrender the disputed original without keeping a complete copy.

When legal help is urgent

Consult a Philippine lawyer promptly when:

the affidavit concerns land, inheritance, corporate control, a substantial debt, or transfer of ownership;
a filing, appeal, tax, registration, prescription, or court deadline is near;
the affidavit may admit criminal conduct or expose someone to prosecution;
you are being pressured to sign facts you do not understand or know to be false;
the signer is a minor, incapacitated, seriously ill, unable to read, or unable to communicate conventionally;
authority to sign for another person or entity is disputed;
the document was signed abroad or will be used in another country;
a signature or notarization appears forged, backdated, or fabricated;
the notary’s commission or register entry cannot be verified; or
an office has rejected the affidavit and the defect could affect a legal right.

In an active case, follow the court’s order and consult counsel rather than relying on a general-purpose affidavit template.

Frequently asked questions

Can I sign the affidavit before visiting the notary?

Usually not if the affidavit requires a jurat. A jurat requires signing in the notary’s presence. Ask the notary before signing.

Are two valid IDs always required?

The Supreme Court rule generally refers to at least one current official identification document bearing both photograph and signature. A notary or receiving institution may request another ID to resolve a discrepancy or comply with a lawful verification policy.

Is a barangay clearance or certification enough?

Only if the particular document qualifies under the competent-evidence rule and contains the required identifying features. Confirm with the notary in advance. A cedula alone is insufficient.

Can a relative take my affidavit to the notary?

No. The affiant must personally appear for traditional notarization. A representative may deliver or file an affidavit after it has been validly executed, if the receiving office permits.

Can I notarize a photocopy?

A notary does not automatically certify the truth or authenticity of an underlying record merely by notarizing a statement attached to a photocopy. Ask the receiving office whether it needs an affidavit, a certified true copy from the issuing custodian, or another form of authentication.

Is an electronically signed affidavit automatically notarized?

No. An electronic signature and electronic notarization are distinct. Valid electronic notarization must follow A.M. No. 24-10-14-SC through an authorized facility and commissioned Electronic Notary Public.

Does notarization prove the affidavit is true?

No. It gives the document public character when properly performed and certifies the notarial act. The affidavit’s factual truth can still be challenged.

How much does notarization cost?

The 2004 Rules require notarial fees to be collected in accordance with the fee schedule displayed by the notary. Charges may vary with the document and authorized local schedule. Ask the notary for the fee and an official receipt before proceeding; unusually high “processing” charges may include services beyond notarization.

Can an affidavit be corrected after notarization?

Do not erase, overwrite, replace pages, or insert material information. For a substantive error, execute and notarize a corrected or supplemental affidavit and disclose the earlier document where necessary.
