Quick answer

An affidavit is a written statement of facts that the person making it—the affiant—swears or solemnly affirms to be true. For an ordinary paper affidavit in the Philippines, the affiant generally must:

state facts within the affiant’s personal knowledge;
use the correct affidavit required by the court, agency, or transaction;
leave no material blanks or incomplete attachments;
personally appear before a duly commissioned notary public;
present acceptable proof of identity;
sign the affidavit in the notary’s presence; and
take an oath or affirmation before the notary.

The notary should then complete and sign the jurat, affix the official seal, and enter the act in the notarial register. A paper affidavit cannot validly be notarized merely because someone delivers a pre-signed document and a photocopy of the affiant’s ID to a notarial office.

Electronic notarization is now legally recognized for qualifying electronic documents, but it must follow the Supreme Court’s official electronic-notarization system and cannot be replaced by an informal video call, emailed scan, or pasted electronic signature.

Notarization verifies matters such as personal appearance, identity, signing, and administration of the oath. It does not prove that every factual statement is true, cure a legally defective document, transfer property by itself, or guarantee that a court or government office will accept the affidavit.

When is an affidavit required?

There is no single rule requiring every declaration or transaction to be placed in an affidavit. An affidavit is usually needed when a law, court rule, government agency, contract, or receiving institution requires a sworn statement. Common examples include:

affidavits of loss;
complaint-affidavits and counter-affidavits in criminal proceedings;
affidavits of witnesses;
affidavits of discrepancy, identity, or one and the same person;
affidavits of support, consent, or undertaking;
affidavits used in estate, land, tax, employment, immigration, or administrative matters; and
sworn explanations or certifications required by a particular office.

Requirements differ substantially. A generic affidavit may be insufficient where a prescribed form, specific allegations, supporting documents, witnesses, photographs, certifications, or filing deadline applies. Obtain the latest checklist directly from the court, agency, embassy, school, bank, employer, or other recipient before preparing the document.

What a proper affidavit should contain

The exact form depends on its purpose, but a usable affidavit ordinarily includes:

a clear title identifying the type of affidavit;
the affiant’s complete name and relevant personal details;
a statement that the affiant is competent to testify to the stated facts;
numbered paragraphs presenting facts in a clear, chronological order;
identification of attached documents, where applicable;
the purpose for which the affidavit is executed;
the affiant’s signature; and
a complete jurat for the notary.

Include only personal information genuinely needed for the stated legal purpose. Avoid publishing full identification numbers, home addresses, signatures, or sensitive attachments in public copies unless required.

Facts, not arguments or guesses

An affiant should distinguish among:

facts personally seen, heard, done, received, or recorded;
information learned from another person;
conclusions or opinions; and
assumptions that have not been verified.

If information comes from a record, identify the record and attach a legible copy when required. If a date or detail is uncertain, do not guess. State the limitation accurately or confirm the information before swearing to it.

Attachments

Label attachments consistently—for example, “Annex A”—and refer to them in the relevant paragraph. Check that:

every cited attachment is present;
pages are complete and readable;
names, dates, and reference numbers match the affidavit;
translations or certifications are supplied when required; and
alterations are explained and properly initialed if the receiving office permits them.

Do not attach an original document unless the recipient specifically requires it. Preserve the original separately whenever possible.

Jurat versus acknowledgment

An affidavit normally requires a jurat, not merely an acknowledgment.

Jurat

Under the notarial rules, a jurat involves an individual who, on one occasion:

personally appears before the notary;
presents the document;
is personally known to the notary or properly identified;
signs the document in the notary’s presence; and
takes an oath or affirmation concerning the document.

The jurat commonly begins with words such as “Subscribed and sworn to before me,” but the wording alone is not enough. The required acts must actually occur.

Acknowledgment

In an acknowledgment, the person personally appears, is properly identified, and declares that the signature and document are the person’s free and voluntary act or deed. An acknowledgment is commonly used for contracts, deeds, powers of attorney, and similar instruments.

An acknowledgment ordinarily does not substitute for the oath required for an affidavit. Conversely, adding a jurat does not necessarily satisfy a law or transaction that specifically requires an acknowledgment.

The distinction matters because the notary certifies different facts. Do not simply copy a notarial block from an unrelated document.

Personal appearance is mandatory for paper affidavits

For a paper affidavit bearing a handwritten or wet signature, the affiant must personally appear before the notary at the time of the notarial act. The Supreme Court has repeatedly treated notarization without the signatory’s personal presence as a serious violation.

Do not use arrangements in which:

a relative, liaison, or office messenger appears for the affiant;
the affidavit and ID are sent through email or a messaging application;
a secretary signs or completes the notarial act for the lawyer;
the notary’s signature or seal is already printed on a blank form; or
the affidavit is supposedly notarized through an ordinary video call outside the official electronic-notarization framework.

If illness, disability, detention, hospitalization, or another serious condition prevents travel, contact a commissioned notary in advance. The traditional rules contain limited circumstances in which a notarial act may be performed outside the notary’s regular place of work or business, including certain public-interest or exceptional situations. Availability and legal compliance must be confirmed with the notary; inconvenience alone should not be assumed to create an exception.

Identification requirements

Under the amended definition of competent evidence of identity, identification may be established through at least one current identification document issued by an official agency that bears the individual’s photograph and signature. Examples identified in the rules include a passport, driver’s license, PRC ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen card, government-office ID, and other qualifying government-issued documents.

A notary may decline an ID that is expired, damaged, illegible, inconsistent with the affidavit, missing a photograph or signature, or otherwise inadequate to establish identity. Bring the original ID, not only a screenshot or photocopy. It is practical to bring a second current government-issued ID in case further verification is reasonably required.

When a qualifying ID is unavailable, the rules provide a credible-witness method:

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 privy to the instrument, document, or transaction. This is not simply permission to bring any friend or relative. Arrange the procedure with the notary beforehand.

Names in the affidavit should match the identification presented. Explain material spelling, surname, or civil-status discrepancies and bring supporting records if relevant.

What the affiant should do at the notary’s office

Before signing, read every page and confirm that it accurately reflects the facts. Then:

Show the notary the complete unsigned affidavit and all attachments.
Present the original identification required by the rules.
Answer identity, capacity, and voluntariness questions truthfully.
Sign the affidavit in the notary’s presence.
Take the oath or solemn affirmation administered by the notary.
Check the completed jurat before leaving.
Confirm that the notarial details are complete and consistent.
Obtain the number of original or certified copies required by the recipient.
Keep a complete copy for your records.

The notarial certificate should not be blank or incomplete. It ordinarily identifies the place and date of notarization and contains the notary’s signature, seal, commission details, and document, page, book, and series information. The affiant should not fill in or alter the notary’s official entries.

Under the 2025 amendments to the traditional notarial rules, notaries also have updated electronic recordkeeping and reporting duties. A notary must provide or transmit an electronic copy of the notarized document as required by the amended rules, without an additional charge for that transmission. These administrative duties do not eliminate the affiant’s obligation to preserve a complete copy.

When a notary must refuse

A notary should not proceed when, among other problems:

the signatory is not personally present under the applicable procedure;
identity cannot be established;
the document or notarial certificate is incomplete;
the notary knows or has good reason to believe the transaction is unlawful;
the signatory appears unwilling, coerced, or unable to understand the act;
the notary has a disqualifying personal interest;
the notary is a spouse, common-law partner, ancestor, descendant, or relative of the principal within the prohibited degree; or
the requested act falls outside the notary’s authority or territorial jurisdiction.

A notary public is not merely a person who sells a stamp. The commission belongs personally to the commissioned lawyer; a secretary, assistant, or employee cannot perform the notarial act or sign for the notary.

Does notarization make the affidavit true or legally sufficient?

No. Proper notarization gives a document important evidentiary status, but it does not establish the truth of every statement beyond dispute.

The Supreme Court explains that notarization converts a private document into a public document and permits reliance on its apparent authenticity and due execution. That presumption may still be challenged with competent evidence. Improper notarization can deprive a document of its public-document character, leaving its authenticity and execution to be proved as with a private document.

Notarization also does not:

establish facts outside the affiant’s knowledge;
make hearsay automatically admissible;
replace required witnesses or supporting evidence;
cure lack of legal capacity or authority;
validate an unlawful agreement;
correct a defective land conveyance;
satisfy a missed filing deadline; or
guarantee acceptance by the intended recipient.

The affidavit’s legal effect therefore depends on its contents, supporting evidence, purpose, and compliance with the law or procedure governing the particular matter.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, took effect in March 2025. They supplement rather than replace traditional notarization.

The framework allows:

In-Person Electronic Notarization, where an electronic document is notarized through an accredited Electronic Notarization Facility and the participants physically appear before an Electronic Notary Public; and
Remote Electronic Notarization, where the participants appear virtually through an accredited facility and comply with the prescribed identity, signing, recording, and security controls.

The electronic rules apply to electronic documents with electronic signatures. Paper documents with handwritten signatures remain governed by the traditional notarial rules.

Electronic notarization is not accomplished merely by:

scanning a signed paper affidavit;
sending an ID and signature by email;
meeting a lawyer through an ordinary video-conferencing application;
inserting a digital image of a seal; or
using a person or platform that is not duly authorized.

Before using an electronic service, verify that the lawyer is a qualified Electronic Notary Public and that the service uses an accredited Electronic Notarization Facility. The electronic rules also contain exclusions and special requirements for particular documents and circumstances. For example, they do not create an electronic-notarization route for wills.

A principal outside the Philippines may use electronic notarization only under the limited conditions stated in the rules, including applicable Philippine diplomatic or consular arrangements. Do not assume that any person abroad can remotely notarize a document from a home or workplace.

The temporary pandemic-era rules on remote notarization of paper documents have been repealed. Current transactions should be checked against the 2025 rules and the Supreme Court’s implementation guidance.

Affidavits executed outside the Philippines

A person abroad may generally execute an affidavit before an authorized Philippine embassy or consulate, subject to that post’s appointment system, forms, identification rules, fees, and local procedures.

Another possible route is execution before a local notary or other authorized official, followed by an apostille or authentication process when required. The correct procedure depends on:

the country where the document is executed;
whether that country and the Philippines apply the Apostille Convention to each other;
the type of document;
the intended use in the Philippines; and
the requirements of the Philippine recipient.

An apostille authenticates the origin of the relevant public document or certification; it does not certify that the affidavit’s factual statements are true. Confirm requirements with the receiving Philippine office and the relevant embassy, consulate, or competent apostille authority before signing.

For Philippine documents intended for use abroad, consult the Department of Foreign Affairs’ official Apostille requirements and verify whether the destination country or recipient requires an apostille, consular legalization, translation, or another certification.

Deadlines and validity periods

There is no universal rule that every affidavit expires after three or six months. An affidavit records facts sworn to on a particular date. Whether it remains acceptable depends on:

the law or procedure governing the application or case;
a validity period imposed by the receiving institution;
whether the facts remain current;
whether a prescribed form has changed; and
whether a filing, appeal, response, registration, or application deadline applies.

An agency may require a recently executed affidavit even though the older affidavit did not automatically become void. Conversely, re-notarizing the same statements does not revive a missed legal deadline.

For court, prosecution, immigration, bidding, tax, licensing, employment, and land matters, verify the filing deadline independently. Do not treat the date of notarization as the filing date unless the governing rule expressly says so.

Evidence and records to preserve

Keep:

the final signed and notarized affidavit;
every page and attachment submitted with it;
copies of the identification presented;
source records supporting material statements;
drafts showing corrections to significant facts;
filing receipts, reference numbers, and acknowledgment emails;
proof of delivery or electronic filing;
the recipient’s checklist or instructions in effect at the time; and
any electronically notarized file, verification data, and related certificate in its original digital form.

Do not edit an electronically notarized file or detach its verification information. For paper documents, avoid separating annexes or replacing pages after notarization. If a material correction is needed, prepare and properly execute a corrected or supplemental affidavit rather than altering the notarized original.

Common mistakes

Signing before meeting the notary

A jurat requires signing in the notary’s presence. Ask the notary before signing, even if someone else prepared the affidavit.

Using the wrong notarial certificate

An acknowledgment is not automatically interchangeable with a jurat. The document’s purpose determines the required act.

Leaving blanks

Blank dates, amounts, names, property descriptions, or annex references create serious risks. The notary should not notarize an incomplete document.

Copying facts from a template without checking them

Templates often contain statements suited to a different transaction. Delete inapplicable clauses and verify every remaining assertion.

Treating notarization as legal advice

The notary’s function does not necessarily include advising the affiant on rights, tax consequences, property ownership, criminal exposure, or litigation strategy. Obtain separate legal advice when the substance matters.

Assuming any lawyer may notarize anywhere

A lawyer must hold a valid notarial commission and generally acts within the territorial jurisdiction stated in that commission. Ask to see the commission details if authenticity is in doubt.

Using informal “online notarization”

A video call and emailed scan do not satisfy the current electronic rules unless the process takes place through the authorized framework.

Swearing to facts that cannot be verified

Careless, exaggerated, or knowingly false statements can cause rejection, civil consequences, loss of credibility, or criminal exposure.

False affidavits and possible liability

A person should never sign an affidavit known to contain a material falsehood. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, perjury may arise from a knowingly untruthful material statement made under oath before a competent officer when the law requires the statement or it is made for a legal purpose.

Perjury is not established merely because another person disputes the affidavit or because the affiant made an innocent mistake. The elements include a willful and deliberate assertion of a material falsehood. Other offenses or liabilities may apply depending on how a false or fabricated document is prepared, used, or submitted.

If an already filed affidavit contains a significant error, do not secretly replace pages or ask the notary to change the original entry. Obtain legal advice on whether to execute a correction, supplemental affidavit, retraction, manifestation, or other appropriate filing.

When legal help is urgent

Consult a Philippine lawyer promptly if:

the affidavit concerns an arrest, criminal complaint, subpoena, or preliminary investigation;
a filing or response deadline is near;
the document concerns land, inheritance, corporate authority, immigration status, or a substantial financial obligation;
another person prepared statements you do not understand or cannot verify;
you are being pressured to sign;
a signature, seal, ID, or notarization appears forged;
pages were replaced or altered after signing;
the supposed affiant never appeared before the notary;
the affidavit has already been submitted and contains a material error;
the document will be used in another country; or
a court, prosecutor, agency, or foreign authority has rejected it.

For possible misconduct by a notary, preserve the original document, envelope, messages, receipts, photographs, and proof of the signatory’s location. The Executive Judge of the Regional Trial Court with supervisory authority over the notary’s commission may have a role in notarial disciplinary proceedings. A lawyer can help identify the correct forum and remedy without risking loss of evidence or missed deadlines.

Frequently asked questions

Can I write my own affidavit?

Yes, unless a prescribed form or special rule applies. The document must still contain the necessary facts and satisfy the recipient’s substantive and procedural requirements. For high-stakes matters, legal review is advisable.

Must an affidavit be notarized?

An affidavit is ordinarily sworn or affirmed before an officer authorized to administer oaths. If the law or recipient requires an affidavit, an unsigned or unsworn statement generally will not be an adequate substitute. Some proceedings allow other verified declarations or certifications, but only where the applicable rule authorizes them.

Can I use an expired ID?

A current qualifying government-issued identification document is the general requirement. Confirm an alternative identification procedure with the notary rather than assuming an expired ID will be accepted.

Can I sign at home and send the document to the notary?

Not for an ordinary paper affidavit requiring a jurat. The affiant must sign in the notary’s presence. Electronic documents must follow the separate official electronic-notarization rules.

Can a representative have my affidavit notarized for me?

No. Personal appearance, identification, signing, and the oath cannot be delegated to a representative.

Can the notary correct my affidavit?

Minor corrections should be addressed before signing and notarization. A notary should not unilaterally rewrite the affiant’s factual statements or alter a completed affidavit. Material post-notarization changes normally require a newly executed document or another legally appropriate correction.

Is a notarized photocopy the same as an original affidavit?

No. A photocopy, certified copy, and original signed affidavit are different. The recipient determines which form is acceptable.

How much does notarization cost?

There is no single nationwide price for every affidavit. Charges may depend on the service, document, locality, applicable fee schedule, and additional legal work. Ask for the fee before proceeding and request a receipt where appropriate.

How long does an affidavit remain valid?

There is no universal expiration period. The receiving office may impose a recency requirement, and changed facts may make an older affidavit inaccurate or unsuitable.

Does notarization prove ownership or win a case?

No. It helps establish authenticity and due execution but does not conclusively establish ownership, truth, liability, or entitlement to relief.
