Quick answer

An affidavit is a written statement of facts made under oath or affirmation. In the Philippines, it is ordinarily completed through a jurat: the affiant personally appears before a duly commissioned notary public or another officer authorized to administer oaths, proves identity, signs the complete document in that officer’s presence, and swears or affirms that its contents are true.

For a standard paper affidavit:

Use the form required by the court, agency, bank, school, employer, or other recipient.
State facts accurately and, as far as possible, from personal knowledge.
Bring the complete but unsigned affidavit, supporting originals, and at least one current official identification document bearing your photograph and signature.
Appear personally before the notary. A representative cannot appear or take the oath for you.
Sign only when instructed, take the oath or affirmation, and check the completed jurat and notarial details before leaving.

A scan, photocopied signature, video call with an ordinary notary, acknowledgment performed without an oath, or notarization obtained while the affiant is absent does not satisfy the ordinary requirements. Electronic notarization is possible only under the Supreme Court’s separate rules and through a properly commissioned Electronic Notary Public—not through an informal online arrangement.

What an affidavit does—and does not do

An affidavit records a person’s sworn factual statement. Common examples include affidavits of loss, discrepancy, support, consent, service, adverse claim, complaint, desistance, or two disinterested persons.

Proper notarization gives a private document the public character and evidentiary treatment recognized by law. It helps establish that the identified person personally appeared, signed, and took an oath. The Supreme Court repeatedly emphasizes that notarization is a substantive safeguard, not a routine stamp. See the 2004 Rules on Notarial Practice and Calubaquib v. Pascua, A.C. No. 10562.

Notarization does not:

prove conclusively that every statement in the affidavit is true;
make hearsay, speculation, or otherwise inadmissible material automatically admissible;
correct false facts, an unlawful transaction, lack of authority, forgery, or incapacity;
guarantee that a court or agency will accept the document;
replace registration, apostille, publication, service, filing, or other requirements imposed by a particular law; or
turn the notary into a witness with personal knowledge of the events described.

Defective notarization generally strips a document of its public character and reduces it to a private document that must be proved under the applicable rules of evidence. Whether the underlying act remains valid depends on the particular document and the law governing it. The consequences are therefore not identical for an affidavit, contract, deed, mortgage, will, or registrable property instrument. See Heirs of Gabule v. Jumuad, G.R. No. 238325.

Jurat versus acknowledgment

These notarial acts serve different purposes.

Jurat

A jurat is normally required for an affidavit. The affiant:

personally appears before the notary;
presents the complete affidavit;
is personally known to the notary or properly identified;
signs in the notary’s presence; and
takes an oath or affirmation that the statements are true.

An affirmation has the same legal effect as an oath and may be used by someone who objects to a religious oath.

Acknowledgment

In an acknowledgment, a person personally appears, presents an integrally complete instrument, and declares that the signature was voluntarily affixed and that the instrument is the person’s free and voluntary act. A representative must also declare authority to sign in that capacity.

An acknowledgment alone is ordinarily not the correct act for an affidavit because it does not substitute for swearing or affirming the truth of the statements. If the document is labeled “Affidavit” but ends only in an acknowledgment, ask the recipient or a lawyer whether it must be corrected and executed with a jurat.

What information should appear in an affidavit?

There is no single universal form. A statute, court rule, government agency, or receiving institution may prescribe exact language and attachments. Subject to those requirements, an affidavit commonly contains:

the country and city or province relevant to the notarial venue;
a descriptive title;
the affiant’s full legal name and necessary identifying circumstances;
a statement that the affiant was duly sworn;
consecutively numbered factual allegations;
an explanation of the affidavit’s purpose;
references to clearly labeled attachments, if any;
the affiant’s signature over the printed name; and
a completed jurat.

A basic structure may look like this:

REPUBLIC OF THE PHILIPPINES )
CITY/PROVINCE OF _________ ) S.S.

AFFIDAVIT

I, [full legal name], [relevant personal circumstances], after having
been duly sworn in accordance with law, state:

1. [Fact personally known to the affiant.]

2. [Further fact, including dates, names, places, and source of
   knowledge where relevant.]

3. [Purpose for which the affidavit is executed.]

I execute this affidavit to attest to the truth of the foregoing and
for [specific lawful purpose].

[Signature over printed name]
Affiant

JURAT
[To be completed by the notary or authorized officer]

Do not copy this skeleton when a prescribed form exists. An affidavit of loss, complaint-affidavit, judicial affidavit, affidavit involving land, or document for foreign use may require substantially different content.

How to state the facts safely and clearly

An affidavit should contain facts, not advocacy disguised as fact.

Use the correct legal names appearing on official records.
Give specific dates, places, amounts, document numbers, and events when known.
Distinguish what you personally saw, heard, did, or received from information supplied by someone else.
If you do not remember an exact detail, say so instead of guessing.
Do not describe an assumption as personal knowledge.
Explain any relevant discrepancy in names, dates, signatures, or records.
Identify each attachment in the text and label it consistently.
Avoid unnecessary sensitive information, but include information expressly required by the recipient.
Read every paragraph and attachment before taking the oath.

For a joint affidavit, every affiant must review the document, personally appear, prove identity, sign, and take the oath. One affiant cannot complete the notarization for the others.

Identification requirements

Under the 2004 Rules, as amended in 2008, “competent evidence of identity” includes at least one current identification document issued by an official agency and bearing the individual’s photograph and signature. Examples commonly capable of satisfying those features include a current passport, driver’s license, or PRC identification card. The controlling test is not merely that a card is “government-issued”; it must meet the rule’s identifying requirements.

A community tax certificate or cedula is not sufficient identification for this purpose because it does not provide the required photograph-and-signature safeguards. See Edayan v. Garcio, A.C. No. 12084, and the Supreme Court’s 2008 amendment on competent evidence of identity.

If the affiant lacks acceptable documentary identification, the Rules provide a credible-witness route:

one credible witness who is not involved in the document or transaction, is personally known to the notary, and personally knows the affiant; or
two credible witnesses who are not involved in the document or transaction, personally know the affiant, and present documentary identification to the notary.

This is not satisfied merely by bringing a relative, co-signatory, buyer, seller, or other person interested in the transaction.

The general Notarial Rules do not require a photocopy of the presented ID to be attached to every affidavit. A court, agency, recipient, or notary’s lawful recordkeeping process may nevertheless require a copy. Bringing the original and photocopies avoids delay.

Personal appearance is mandatory for ordinary paper notarization

The person whose affidavit is being notarized must be personally present. The notary must be able to identify the affiant, observe the signing, administer the oath or affirmation, and assess whether the act is voluntary.

The following practices are serious red flags:

leaving a signed affidavit with a secretary, fixer, courier, or relative;
buying a document that already carries a notarial seal;
sending a signed scan for a notary to stamp later;
notarization through an ordinary video call outside the electronic-notarization system;
using the notarial details of a lawyer who was absent;
backdating or antedating the jurat;
notarizing for a person who is abroad, deceased, or otherwise absent; or
signing blank pages to be completed later.

The Supreme Court has consistently disciplined notaries for notarizing without the signer’s personal appearance. See Galano, A.C. No. 11870.

The document must be complete

Do not present an affidavit containing material blanks, missing pages, unidentified attachments, inconsistent names, or an unfinished factual statement. Confirm that:

all pages belong to the same document;
page numbering is consistent;
names and dates match the supporting records;
referenced exhibits are actually attached;
alterations are resolved before signing; and
no material term will be inserted after notarization.

A notarized affidavit should not be altered after the oath. If a material error is discovered, the safer course is usually to prepare a corrected or supplemental affidavit, disclose the earlier error where necessary, and complete a new notarization. Ask the receiving body whether it requires replacement, an affidavit of correction, or both.

What to bring to the notary

Unless the receiving office requires more, bring:

the complete unsigned affidavit;
every attachment referred to in it;
at least one current official ID bearing your photograph and signature;
photocopies of the ID and attachments, if requested;
originals of records whose copies are attached;
proof of authority if signing for an organization or in a representative capacity; and
enough complete sets for filing, service, and your records.

Ask about the fee before the notarial act. The Notarial Rules permit the applicable maximum fee prescribed by the Supreme Court and allow a notary to waive it. The fee must be entered in the notarial register. The 2025 amendments separately prohibit fees for the mandatory digitization, transmission, or processing of the reporting documents required from notaries.

Check the notarization before leaving

The jurat should accurately show the date and place where the oath was administered. The notarial certificate’s concluding portion should contain the required identifying details of the notary, including:

the notary’s commissioned name and signature;
official seal;
notarial commission serial number;
city or province of commission;
commission expiration;
office address;
Roll of Attorneys number;
professional tax receipt details; and
IBP membership details.

The document should also carry its notarial register reference, commonly shown as the document, page, book, and series numbers.

A traditional notarial commission operates only within the territorial jurisdiction of the commissioning court and ordinarily lasts for the two-year term prescribed by the Rules unless earlier revoked or the notary resigns. If authenticity matters, verify the commission with the Office of the Clerk of Court of the Regional Trial Court for the stated city or province. Missing or inconsistent commission details, duplicate register references, an expired commission, or a seal from another locality should be investigated before relying on the document.

Paper and electronic notarization are different systems

The Supreme Court’s 2025 Rules on Electronic Notarization govern authorized electronic notarial acts involving electronic instruments and a specially commissioned Electronic Notary Public.

Electronic notarization is not accomplished merely by:

emailing a scan;
pasting an image of a signature or seal;
using a generic e-signature website;
showing an ID during an ordinary video call; or
asking a traditionally commissioned notary to “notarize online.”

Paper documents and instruments remain governed by the traditional rules. The Supreme Court also states that notarial wills and depositions remain outside the electronic-notarization process described in the new rules. Consult the Supreme Court’s official eNotary FAQs and confirm that the intended recipient accepts the electronic form before proceeding.

A Filipino abroad should not assume that a Philippine paper affidavit can be notarized remotely. Depending on where and how the document will be used, the proper route may be:

execution before a Philippine embassy or consulate offering notarial services;
execution before a competent notary in the foreign country followed by an apostille or authentication, when required; or
electronic notarization under the Supreme Court rules, if every applicable condition can be met.

Consular requirements, appointments, fees, and accepted identification vary by post.

Apostille and foreign use

Notarization and apostille are not the same.

Notarization concerns the signer’s appearance, identity, signature, and oath or acknowledgment. An apostille authenticates the origin of a Philippine public document for use in another Apostille Convention country; it does not certify that the affidavit’s factual statements are true.

Before obtaining either service, ask the foreign recipient:

whether it requires an original, notarized copy, certified copy, or apostille;
whether a translation is required;
how recent the affidavit must be;
whether attachments must also be authenticated; and
whether the receiving country is an Apostille Convention party.

Use the Department of Foreign Affairs’ current documentary requirements and application process. Requirements and filing arrangements can change, so do not rely solely on an old checklist or an intermediary’s assurance.

Deadlines and “validity periods”

There is no universal rule that every affidavit expires after three or six months. Its usefulness depends on:

the date-sensitive facts stated in it;
a statute, court rule, agency circular, or prescribed form;
the recipient’s freshness requirement; and
the filing or transaction deadline for which it was prepared.

An affidavit may remain a record of what was sworn on a particular date while becoming unacceptable for a later application because the receiving body demands a newly executed document.

Court affidavits can have strict deadlines. Under the Judicial Affidavit Rule, judicial affidavits generally replace direct testimony in covered proceedings and must ordinarily be filed and served no later than five days before the relevant pre-trial, preliminary conference, or scheduled hearing for motions and incidents. They require a question-and-answer format, specified contents, counsel’s attestation, and a jurat. Late or noncompliant submissions can be waived, rejected, or allowed only under the Rule’s limited conditions and possible fines. A general narrative affidavit is not an automatic substitute.

False statements and perjury

An affidavit must be truthful. Republic Act No. 11594 increased the penalty for perjury under Article 183 of the Revised Penal Code to prisión mayor in its minimum period. A public officer or employee responsible for the offense faces the penalty in its maximum period, and the law also provides a fine of up to ₱1,000,000 and perpetual absolute disqualification from government office. The prosecution must still establish all legal elements of perjury; not every mistake, inconsistency, or rejected claim automatically constitutes the crime. See Republic Act No. 11594.

Never sign an affidavit merely because someone says it is “only a requirement.” Refuse to sign if:

you have not read the final version;
facts were supplied that you cannot honestly verify;
dates or amounts were changed to fit an application;
the affidavit falsely reports a lost document;
it conceals a sale, payment, death, marriage, ownership interest, or prior filing;
the attachments are altered or incomplete; or
someone asks you to sign blank pages or backdate the oath.

Evidence to preserve

Keep a complete copy of exactly what was notarized, including all attachments and the entire jurat. Preserve:

the original or best available copy;
clear scans of every page;
the notary’s name, office address, commission details, and register reference;
the ID used and proof that it was current on the notarization date;
receipts and appointment confirmations;
drafts showing corrections;
emails or messages transmitting the document;
originals of supporting records; and
proof of filing, service, or receipt by the intended institution.

For an electronically notarized document, preserve the original electronic file—not only a printout—together with its electronic notarial certificate, validation information, and transmission records.

Common mistakes

Signing before meeting the notary when a jurat requires signing in the notary’s presence.
Using an acknowledgment instead of a jurat.
Treating a cedula as sufficient identification.
Bringing an expired, damaged, signature-less, or mismatched ID.
Allowing another person to appear for the affiant.
Leaving blank facts, dates, annex labels, or signature pages.
Using a generic affidavit when the recipient has a prescribed form.
Stating conclusions or second-hand accusations as personal knowledge.
Failing to attach documents expressly mentioned in the affidavit.
Changing the affidavit after notarization.
Assuming notarization automatically satisfies filing, registration, apostille, or evidentiary rules.
Using an expired or territorially unauthorized notary.
Paying a fixer for a document that was supposedly notarized without personal appearance.
Missing the deadline because the affidavit was prepared without first checking the receiving office’s rules.

If a notarized document appears fake or unauthorized

Act promptly, especially if the document concerns land, money, corporate control, inheritance, immigration status, or parental rights.

Preserve the original and make high-quality copies. Do not write on, detach pages from, or “correct” the questioned document.
Record when, where, and from whom it was obtained.
Check the notary’s commission details and the document, page, book, and series numbers.
Ask the appropriate RTC Office of the Clerk of Court about verifying the commission and notarial-register entry.
Secure records showing impossibility or forgery, such as travel records, death certificates, medical records, specimen signatures, title records, messages, or proof that the alleged signer was elsewhere.
Obtain legal advice before confronting suspected participants or surrendering an original.
Depending on the evidence, remedies may include challenging the document in the pending case or transaction, seeking civil relief, filing a criminal complaint, or pursuing an administrative complaint against the lawyer-notary.

An absent or inconsistent register entry is important evidence, but its legal effect must be evaluated with the complete records and circumstances.

When legal help is urgent

Consult a Philippine lawyer immediately if:

an affidavit, deed, waiver, or authority was signed without your consent;
a false notarized document is being used to transfer or mortgage land;
you are being pressured to swear to facts you do not know;
a filing, appeal, immigration, tax, or registration deadline is near;
the affidavit may expose you to criminal liability;
the document concerns child custody, travel consent, domestic violence, detention, or personal safety;
an adverse party has already filed the affidavit in court or with a government agency;
the affiant cannot understand the document or communicate informed consent; or
a foreign recipient has rejected the notarization or demands authentication.

If private counsel is unaffordable, inquire about assistance from the Public Attorney’s Office, an IBP legal-aid office, a law-school legal clinic, or another accredited legal-aid provider, subject to their eligibility and case requirements.

Frequently asked questions

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

For an ordinary jurat, sign in the notary’s presence. If you already signed, disclose that fact. The notary may require a fresh copy or require you to sign again properly; do not ask the notary to certify an appearance or signing that did not happen.

Is one valid ID enough?

The Rules recognize at least one current official identification document bearing the affiant’s photograph and signature. A notary or receiving institution may lawfully require additional proof when identity is uncertain or its own procedure requires more.

Is a cedula a valid ID for notarization?

No. A community tax certificate does not meet the photograph-and-signature requirement for competent evidence of identity.

Does every affidavit need two witnesses?

No. A standard affidavit generally does not require two subscribing witnesses unless a specific law or form says otherwise. Credible identifying witnesses are a separate alternative used when the affiant lacks competent documentary identification.

Can a relative notarize my affidavit?

The 2004 Rules disqualify a notary from acting when the notary is a spouse, common-law partner, ancestor, descendant, or relative of the principal within the fourth civil degree of affinity or consanguinity. Use an independent commissioned notary.

Can an affidavit be notarized through a video call?

Not under the ordinary paper-notarization rules. A lawful electronic notarization must comply with the 2025 Rules and be performed by a properly commissioned Electronic Notary Public through the authorized system.

Does a notarized affidavit expire?

There is no universal expiration period. The receiving office may require a recently executed affidavit, and the facts or underlying application may have a deadline.

Can I correct a typographical error after notarization?

Do not alter a notarized affidavit unilaterally. For a material error, prepare a corrected or supplemental affidavit and have it properly notarized, subject to the recipient’s instructions.

Does notarization make the affidavit automatically admissible in court?

No. Notarization addresses due execution and public character. Relevance, hearsay, authentication of attachments, personal knowledge, filing deadlines, and other evidentiary rules still apply.

Can a notary refuse to notarize?

Yes. A notary must refuse when the act or transaction appears unlawful or immoral, the document or identity requirements are deficient, the signer is absent, the signer does not appear to understand the act or is acting under duress, or the notary is disqualified.

Where can I verify a notary’s commission?

Contact the Office of the Clerk of Court of the Regional Trial Court for the city or province stated in the notarial certificate. Provide the notary’s name, commission details, notarization date, and document, page, book, and series numbers.
