Quick answer

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

use a complete and accurate affidavit;
personally appear before a duly commissioned notary public;
present competent evidence of identity unless personally known to the notary;
sign the affidavit in the notary’s presence;
swear or affirm that its contents are true; and
allow the notary to record the act and complete the jurat.

Do not sign a paper affidavit in advance unless the notary specifically instructs you otherwise. Do not use a scanned signature, send only a photograph of your ID, or ask another person to bring the signed affidavit for notarization. Those shortcuts do not satisfy the personal-appearance requirements for an ordinary paper affidavit.

The applicable requirements depend on the document’s intended use. Courts, prosecutors, government agencies, banks, registries, schools, and foreign authorities may require particular wording, attachments, witnesses, identification documents, documentary stamps, apostille or authentication, filing methods, and deadlines.

What makes a document an affidavit?

A document is not an affidavit merely because it is titled “Affidavit.” Ordinarily, it must contain:

the affiant’s complete name and relevant personal circumstances;
clear statements of fact, preferably arranged in numbered paragraphs;
facts within the affiant’s personal knowledge;
the purpose for which the affidavit is being executed;
references to supporting documents, with properly identified attachments when needed;
the affiant’s signature; and
a jurat completed by the person authorized to administer the oath.

The affiant should understand every statement before signing. If the document is in a language the affiant does not understand, an accurate translation or a document in a language understood by the affiant may be necessary. The notary must not notarize a document if the signatory does not understand the nature or consequences of the transaction or is not acting freely.

An affidavit should distinguish firsthand facts from information received from other people. Conclusions, arguments, guesses, and hearsay do not become personal knowledge merely because they are written under oath.

Jurat and acknowledgment are different

An affidavit ordinarily requires a jurat, not a simple acknowledgment.

In a jurat, the affiant:

personally appears before the notary;
signs the affidavit in the notary’s presence; and
takes an oath or affirmation that the contents are true.

An acknowledgment is used when a person declares before the notary that the person voluntarily signed a document for its stated purpose. The signature may have been placed earlier, provided the signatory personally appears and acknowledges it as their voluntary act. Acknowledgments are commonly used for contracts, deeds, and powers of attorney.

Changing “subscribed and sworn” to “acknowledged” is not a harmless formatting choice. The proper notarial act must correspond to what the law, court, agency, or transaction requires.

Requirements before going to the notary

Bring the following unless the receiving office requires more:

the complete affidavit, with no unexplained blanks;
all pages and attachments referred to in the affidavit;
at least one current identification document issued by an official agency and bearing your photograph and signature;
additional identification if requested for verification;
the original documents supporting important statements, when available;
the names and identification of witnesses, if the particular document requires witnesses; and
an email address where the notary can transmit the digitized copy required by the current notarial rules, unless you validly waive receipt.

Examples of official identification recognized under the amended definition of competent evidence of identity include a passport, driver’s license, PRC ID, government-office ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen card, seaman’s book, alien registration document, and other current government-issued identification bearing the holder’s photograph and signature. A barangay certification or government clearance may qualify when it meets the applicable requirements. The controlling standard is found in the 2004 Rules on Notarial Practice, as amended.

A company ID, school ID, photocopy, expired ID, or purely digital image may not satisfy the rule by itself. Confirm beforehand if your identification is unusual or lacks either a photograph or signature.

If the affiant has no acceptable government-issued ID

Identity may, in the circumstances allowed by the rules, be established through credible witnesses:

one credible witness who is personally known to the notary and personally knows the affiant; or
two credible witnesses who personally know the affiant and present the required documentary identification.

A credible witness must not be a party to or otherwise interested in the instrument or transaction. Bringing a friend or relative does not automatically satisfy this alternative.

What happens during conventional paper notarization?

A proper paper notarization generally follows these steps:

Document review. The notary checks whether the document is complete and whether the requested notarial act is lawful and appropriate.
Personal appearance. The affiant appears physically before the notary at the time of notarization.
Identity verification. The notary examines the affiant’s competent evidence of identity or follows the credible-witness procedure.
Understanding and voluntariness. The notary determines that the affiant understands the document and is signing freely.
Signing and oath. For a jurat, the affiant signs in the notary’s presence and swears or affirms that the statements are true.
Register entry. The notary records the act in the official notarial register, including the date, time, document description, affiant’s details, identification used, fee, and other required information.
Notarial certificate. The notary completes and signs the jurat, affixes the official seal, and supplies the document, page, book, and series details.
Copy and reporting. The notary keeps and transmits the records required under the amended rules.

Under the 2025 amendments, the notary must create the prescribed complete electronic reproduction and generally send an electronic copy to each signatory, at no additional cost, within the period fixed by the rules. A signatory may waive receipt, but the waiver has consequences concerning objections to the completeness of the reproduction.

Personal appearance is essential

A notary must not notarize a paper affidavit if the affiant is absent. The following are improper under the ordinary paper-notarization procedure:

leaving a signed affidavit with a secretary or messenger;
sending the affidavit and an ID through a relative;
asking the notary to sign and seal the document without meeting the affiant;
backdating the jurat;
notarizing a blank or incomplete document;
affixing a notarial seal to a scanned signature; or
treating an ordinary video call as a substitute for a lawful notarial procedure.

The Supreme Court repeatedly emphasizes that notarization is not a meaningless routine. Proper notarization converts a private document into a public document entitled to evidentiary treatment that an unnotarized private document does not automatically receive. See, for example, Valdez v. Hipe, A.C. No. 12443, March 14, 2022.

Can an affidavit be notarized online?

Electronic notarization is legally recognized under the Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC. It is different from emailing a signed paper affidavit to an ordinary notary.

The rules provide for:

in-person electronic notarization, in which the parties and electronic notary are physically together while using an accredited electronic-notarization facility; and
remote electronic notarization, in which appearance occurs through the secure audio-video system of an accredited facility.

Electronic notarization applies to eligible electronic documents and must be performed by a properly commissioned Electronic Notary Public through an accredited Electronic Notarization Facility. Identification, authentication, electronic signing, recording, and security requirements must be followed.

Before using a service advertised as “online notarization,” verify:

the electronic notary’s current commission;
the facility’s accreditation;
whether the document is eligible for electronic notarization;
whether the receiving court, agency, bank, or foreign authority accepts the resulting electronic document; and
whether the proposed process complies with the current rules rather than merely using an ordinary video-call application.

Certain documents remain excluded or governed by other rules, including notarial wills and depositions. A handwritten paper document cannot be converted into a valid electronically notarized document merely by scanning it.

Is notarization always required?

No. The law does not require every written statement, contract, authorization, or agreement to be notarized.

Notarization may nevertheless be required because:

a statute or court rule expressly requires a sworn, verified, or notarized document;
a government agency or receiving institution requires it;
the document must be recorded or registered;
the transaction must appear in a public document; or
notarization is needed for its intended evidentiary use.

Article 1358 of the Civil Code requires specified transactions to appear in a public document, including acts involving real rights over immovable property and certain powers of attorney. However, the effect of noncompliance depends on the transaction. In many cases, the requirement concerns form, proof, convenience, or registrability rather than the agreement’s intrinsic validity. Other transactions—such as a donation of immovable property—have stricter formal requirements affecting validity.

For affidavits, the governing filing rule or agency requirement should always be checked. A declaration that is unsigned, unsworn, improperly notarized, or missing a required jurat may be rejected or treated as having no valid verification.

Special requirements for common affidavits

There is no single universal affidavit template. The necessary contents vary according to purpose.

Affidavit of loss

State, as accurately as possible:

what was lost;
identifying numbers and distinguishing details;
when and where it was last possessed;
how the loss was discovered;
the efforts made to locate it; and
whether it was surrendered, transferred, confiscated, or used as security.

The issuing institution may require its own form, incident report, clearance, replacement fee, or waiting period. An affidavit of loss does not automatically cancel a negotiable instrument, transfer ownership, or compel replacement.

Affidavit of discrepancy or one-and-the-same-person affidavit

Identify each differing name, date, address, or record, explain the reason for the discrepancy, and attach the relevant civil-registry or identification documents. An affidavit cannot by itself amend a civil-registry entry when a judicial or administrative correction under the applicable law is required.

Affidavit of support or undertaking

Specify the parties’ relationship, the extent and duration of support, the source of funds, and the purpose of the undertaking. Immigration, school, travel, and consular authorities may require proof of income, relationship, accommodation, or financial capacity in addition to the affidavit.

Affidavit for a court or prosecutor

Follow the governing procedural rule, prescribed form, page limits, required attachments, venue, and filing deadline. A complaint-affidavit, counter-affidavit, judicial affidavit, verification, or certification against forum shopping serves a distinct legal function. One should not be substituted for another without checking the applicable rules.

A judicial affidavit, in particular, must comply with the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, including its question-and-answer form and lawyer’s attestation requirements.

Who may notarize an affidavit?

For ordinary private practice, the notary must be a Philippine lawyer holding a valid notarial commission issued for the relevant territorial jurisdiction. Being a lawyer does not automatically authorize a person to notarize documents.

A notary generally performs conventional notarial acts within the territorial jurisdiction of the commissioning court and at the regular place of work or business stated in the commission. Performance elsewhere is permitted only in circumstances allowed by the rules, such as at an appropriate public place, residence, hospital, detention facility, or another place justified by the signing, confinement, emergency, or legal necessity.

A notary must refuse the act when disqualified by a prohibited personal relationship or direct interest in the transaction, or when the document or circumstances violate the rules.

Notarial fees and additional charges

The amount payable may depend on the applicable local fee schedule and the document or service involved. Ask for the fee before proceeding and request a receipt when appropriate.

Under the 2025 amendments, a notary may not impose a separate charge for digitizing, transmitting, storing, disposing of, or otherwise processing the electronic duplicate required by the notarial rules. This restriction does not necessarily eliminate legitimate fees for separate professional work, such as drafting, revising, translating, or giving legal advice, provided the services and charges are accurately described.

Documents executed outside the Philippines

If an affidavit will be signed abroad, ask the receiving Philippine court, agency, bank, or registry which route it accepts. Depending on the country and purpose, the document may be:

sworn before a Philippine embassy or consulate authorized to provide notarial services;
notarized before a competent foreign notary and apostilled in a country covered by the Apostille Convention; or
authenticated or legalized through the required process when the Apostille Convention does not apply.

An apostille authenticates the origin of the public document—such as the signature, capacity, and seal of the foreign official. It does not establish that every factual statement in the affidavit is true or that the document satisfies the substantive requirements of the Philippine transaction.

Consular forms, appointment systems, fees, personal-appearance rules, and mailing procedures differ by post. Check the official website of the Philippine embassy or consulate concerned and the Department of Foreign Affairs before signing.

What notarization does—and does not—prove

Proper notarization provides official assurance concerning the notarial act, the signatory’s appearance and identification, and the declarations stated in the notarial certificate. It does not:

prove that every factual allegation in the affidavit is true;
make an illegal transaction lawful;
cure lack of authority or legal capacity;
transfer property by itself;
correct a civil-registry or land-title entry;
replace required supporting evidence;
guarantee acceptance by every receiving institution; or
protect an affiant who deliberately makes a false statement.

An affidavit remains evidence that may be admitted, challenged, contradicted, or assigned limited weight depending on the applicable rules and the other evidence.

Consequences of a defective notarization

The legal effect depends on the defect and the purpose of the document. A defective notarization may:

cause rejection by a court, prosecutor, agency, bank, registry, or foreign authority;
prevent the document from being treated as a public document;
require proof of authenticity as a private document;
invalidate a verification or sworn submission;
affect registrability or compliance with a statutory form;
expose the notary to administrative discipline; or
expose a person involved in fabrication, false statements, or use of a falsified document to civil, criminal, or administrative proceedings.

A defect in notarization does not invariably invalidate the underlying transaction. Courts distinguish between formalities required for validity and those required only for enforceability, proof, or convenience. The document and governing law must be examined before reaching a conclusion.

Evidence to preserve

Keep:

the original notarized affidavit;
the electronic copy transmitted by the notary;
all attachments and documents shown to the notary;
the identification document used;
the official receipt or proof of payment;
emails, appointment confirmations, and transmission records;
the notary’s name, commission details, office address, and contact information;
filing receipts or receiving copies from the court or agency; and
earlier drafts if a dispute concerns unauthorized alterations.

Compare the electronic copy sent by the notary with the paper document immediately. If there is a material discrepancy, notify the notary promptly in writing and keep proof of the notice.

If authenticity is disputed, a certified copy or certification concerning the notarial record may be requested from the Office of the Clerk of Court that supervises the notary, subject to applicable procedures.

Common mistakes to avoid

Signing before meeting the notary when a jurat is required.
Using an acknowledgment when the document must be sworn.
Leaving names, dates, amounts, properties, or attachments blank.
Using an expired, altered, or borrowed ID.
Assuming that any lawyer may notarize anywhere in the Philippines.
Paying someone who notarizes without personal appearance.
Allowing another person to add statements after notarization.
Using a generic internet template without checking the receiving office’s requirements.
Treating notarization as proof that the facts are correct.
Executing an affidavit of loss for an item that was sold, pledged, confiscated, or deliberately surrendered.
Filing after the applicable deadline because the affidavit was notarized on time.
Assuming that a document notarized in the Philippines will automatically be accepted abroad.
Assuming that an ordinary video call is valid remote electronic notarization.

When legal help is urgent

Consult a lawyer promptly if:

the affidavit concerns a criminal complaint, arrest, inquest, subpoena, or prosecution deadline;
you are being asked to admit liability, ownership, parentage, debt, fraud, or wrongdoing;
the affidavit relates to land, inheritance, corporate authority, immigration, custody, or a substantial financial transaction;
another person prepared statements you do not understand or know to be inaccurate;
you already signed a false, incomplete, or altered affidavit;
someone forged your signature or used your identity;
a notarized document appears to have been backdated or recorded under false notarial details;
a court or agency has rejected the document;
the affiant cannot personally appear because of illness, detention, disability, location, or another serious obstacle; or
a filing, appeal, replacement, registration, or prescriptive deadline is approaching.

Do not sign merely because someone says the document is “only an affidavit.” Statements under oath can have significant evidentiary and legal consequences.

Frequently asked questions

May I sign the affidavit before going to the notary?

For an affidavit requiring a jurat, the affiant should sign in the notary’s presence after identity and voluntariness have been checked. If you already signed, tell the notary and follow the lawful procedure the notary requires; do not conceal the earlier signing.

Is one valid ID enough?

The rule generally recognizes at least one current official identification document bearing the holder’s photograph and signature. A notary or receiving institution may reasonably require additional proof where identity is uncertain or its own procedure requires more.

Can a notary accept a photocopy or phone image of my ID?

The notary must satisfactorily establish identity through competent evidence. An image alone may be insufficient, particularly for conventional personal appearance. Bring the original current identification document unless the authorized electronic procedure provides another compliant verification method.

Do witnesses have to sign every affidavit?

No. Ordinary affidavits do not universally require instrumental witnesses. Witnesses may be required by the nature of the document, a statute, a prescribed form, or the receiving institution. Credible identifying witnesses are different from instrumental witnesses.

Does the affiant need a community tax certificate or cedula?

A cedula is not a universal substitute for competent evidence of identity under the notarial rules. A particular form, local office, or transaction may separately request its details.

Can the notary draft the affidavit?

A lawyer may separately provide drafting or legal services, but drafting and notarization are distinct services. The affiant remains responsible for reviewing the statements and must not swear to facts that are false or outside personal knowledge.

Does notarization make the document valid forever?

No. Notarization does not eliminate expiration periods, filing deadlines, changed circumstances, revocation, prescription, or agency-specific rules on how recently an affidavit must have been executed.

Can an affidavit be corrected after notarization?

Do not erase, overwrite, insert, or replace pages after notarization. Material changes normally require preparation and execution of a corrected or supplemental affidavit, followed by a new notarial act.

Can someone notarize an affidavit without the affiant present?

Not under the conventional paper procedure. Remote electronic appearance is lawful only through the framework and safeguards established by the Rules on Electronic Notarization.

Is a notarized affidavit automatically accepted in court?

No. It must still comply with the applicable procedural and evidentiary rules. Relevance, admissibility, firsthand knowledge, authentication of attachments, opportunity for cross-examination, prescribed form, and timely filing may all matter.
