Quick answer

An affidavit is a written statement of facts that the affiant swears or affirms to be true before a duly commissioned notary public or another officer authorized to administer oaths. For a valid conventional notarization, the affiant must generally:

personally appear before the notary;
present the complete affidavit, without material blanks;
confirm that the statements are true;
sign or acknowledge the signature before the notary, as the required notarial act demands; and
establish identity through competent evidence of identity.

A community tax certificate or cedula by itself is not competent evidence of identity under the notarial rules because it does not bear both the holder’s photograph and signature. Signing through a representative, sending only a scanned signature, or asking someone else to bring an already signed affidavit to the notary does not satisfy the personal-appearance requirement for conventional notarization.

Electronic notarization is governed by separate Supreme Court rules. It must be conducted by a duly commissioned electronic notary through an authorized electronic-notarization facility and according to prescribed identity, recording, geolocation, electronic-signature, and security safeguards. An ordinary video call or emailed document is not automatically a valid electronic notarization.

What makes a document an affidavit?

A document is not an affidavit merely because it is titled “Affidavit” or contains the words “under oath.” Its essential features ordinarily include:

identification of the affiant;
factual statements based on the affiant’s knowledge or clearly identified sources;
the affiant’s signature or permitted mark;
an oath or affirmation administered by an authorized officer; and
a completed jurat or other proper notarial certificate.

The affiant must understand what the affidavit says. The statements should be accurate, specific, and limited to matters the affiant can truthfully attest to. If the document is in a language the affiant does not understand, it should be translated or adequately explained before execution. The notary may refuse the transaction if there is reason to believe that the affiant does not understand the document or is acting under coercion.

An affidavit containing deliberately false material statements may expose the affiant to criminal liability, including possible perjury under the Revised Penal Code, as amended by Republic Act No. 11594. Whether perjury is established depends on all statutory elements and the particular proceeding or purpose for which the affidavit was made.

Jurat and acknowledgment are not interchangeable

Most affidavits require a jurat, commonly beginning with “Subscribed and sworn to before me.”

In a jurat, the affiant:

personally appears before the notary;
signs the document in the notary’s presence;
takes an oath or affirmation as to the truth of the document; and
is identified through personal knowledge or competent evidence of identity.

An acknowledgment serves a different purpose. The person personally appears and declares that the signature was voluntarily affixed and that the instrument is the person’s free and voluntary act and deed. The rules also address a person signing in a representative capacity, such as for a corporation.

Acknowledgments are ordinarily used for deeds, contracts, powers of attorney, and similar instruments. A document that requires sworn factual testimony should normally have a jurat. The correct certificate depends on the document’s nature and the receiving agency’s requirements.

A notary should not simply replace one certificate with another without considering the legal character of the document.

Identification requirements

Under the amended definition in the 2004 Rules on Notarial Practice, competent evidence of identity generally consists of at least one current identification document issued by an official agency and bearing the holder’s photograph and signature.

Examples identified in the rules include:

passport;
driver’s license;
Professional Regulation Commission ID;
NBI clearance;
police clearance;
government-issued office ID;
GSIS e-card;
SSS card;
PhilHealth card;
senior-citizen ID;
OWWA or OFW ID;
seafarer’s identification document or seaman’s book; and
alien certificate of registration or immigrant certificate of registration.

The list is not necessarily exclusive, but the presented document must satisfy the rule’s characteristics. It must also be current. The notary may request additional identification where the document is damaged, inconsistent, difficult to verify, or insufficient to dispel a reasonable doubt about identity.

A National ID or another current official identification credential may be assessed under the governing notarial rule and the law or official issuances applicable to that credential. Bring the physical or officially recognized form accepted for the transaction rather than relying only on an unverified screenshot or photocopy.

If the affiant has no acceptable ID

The rules recognize identification through credible witnesses in specified circumstances:

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

A notary is not required to accept an arrangement that does not satisfy these safeguards. Contact the notary beforehand if identification will depend on credible witnesses.

Is a cedula enough?

No. Supreme Court decisions have repeatedly explained that a community tax certificate is not competent evidence of identity under the current definition because it lacks the required photograph and signature. It may be requested for another lawful purpose, but it does not substitute for competent identification.

Personal appearance is mandatory

For conventional notarization, personal appearance means actual appearance before the notary at the time of the notarial act. The following practices are improper:

leaving a signed affidavit with a secretary, messenger, relative, or lawyer for later notarization;
asking the notary to notarize based solely on familiarity with the person’s name;
notarizing through an ordinary phone or video call outside the governing electronic-notarization system;
signing blank pages that will be completed later; or
using a signature specimen without the required appearance, identification, and oath or acknowledgment.

A notarized document that falsely states that a person appeared before the notary can be challenged. The notary may also face administrative sanctions, including revocation of the notarial commission, disqualification from being commissioned, suspension from law practice, or other sanctions depending on the offense and circumstances.

Where conventional notarization must take place

A conventional notary public exercises authority only within the territorial jurisdiction stated in the notarial commission. The notarial act must ordinarily occur within that jurisdiction.

A notary may generally perform notarial acts at a regular place of work or business within the commissioned territory. The rules recognize limited situations in which notarization may be performed at another appropriate place within the same territorial jurisdiction, including when requested by a person confined in a hospital or similar institution, a person detained in prison or another place of detention, or a person physically unable to travel to the notary’s office.

Notaries and commissioning courts may impose operational requirements consistent with the rules. Before arranging a hospital, detention-facility, or home visit, confirm the notary’s commission, territorial authority, availability, and required supporting documents.

When a notary must or may refuse

A notary must not perform a notarial act when prohibited by the rules. Important grounds include situations where:

the signatory or affiant is not personally present;
identity has not been properly established;
the document is blank or materially incomplete;
the transaction is unlawful or intended to achieve an unlawful or improper purpose;
the person does not appear to understand the nature or consequences of the transaction;
the person’s apparent will is affected by coercion, intimidation, or undue influence;
the notary is a party to the instrument or will receive a direct commission, fee, advantage, right, title, interest, cash, property, or other consideration beyond the proper notarial fee; or
the notary is otherwise disqualified under the rules.

Family relationship is also regulated. A notary is disqualified when the signatory or witness falls within the prohibited degree of relationship specified by the rules.

A notary is not merely a signature-and-seal service. The notary has an independent duty to verify appearance, identity, voluntariness, and compliance with the required notarial act.

What to prepare before going to the notary

Bring the following, as applicable:

the complete affidavit, with no unexplained material blanks;
a current government-issued identification document bearing your photograph and signature;
the original or reliable copies of documents mentioned as annexes;
proof of authority if signing for a corporation, association, estate, minor, or another person;
credible witnesses and their identification documents if that method of identification will be used;
any format, number-of-copies, documentary-stamp, or filing requirements imposed by the receiving court, agency, embassy, school, bank, or private institution; and
an interpreter or appropriate assistance if necessary, subject to the notary’s compliance requirements.

Do not sign a conventional affidavit in advance unless the notary specifically confirms that the applicable notarial act permits acknowledgment of an existing signature. A jurat normally requires signing in the notary’s presence.

The affiant should read every page, verify all names, dates, addresses, identification details, and annex references, and correct errors before notarization. Corrections made after notarization may require re-execution and a new notarial act.

Electronic notarization

The Supreme Court’s Rules on Electronic Notarization recognize electronic notarial acts, including acknowledgment, oath or affirmation, jurat, and signature witnessing, subject to their specific requirements.

Electronic notarization is not accomplished simply by:

emailing a PDF to a lawyer;
displaying an ID during an ordinary video call;
attaching an image of a signature;
using a generic e-signature application; or
asking a conventionally commissioned notary to conduct the transaction online.

The process must involve a properly commissioned electronic notary public and a Supreme Court-authorized or accredited electronic-notarization facility. Depending on the notarial act, the system incorporates safeguards such as real-time interaction, electronic identity verification, electronic signatures and seals, audiovisual recording, location verification, secure recordkeeping, and an electronic notarial book.

The principal and witnesses must comply with the facility’s technical and identity-verification requirements. Pre-recorded appearances cannot replace the required synchronous interaction. Because implementation, commissioned providers, and available facilities may change, verify the current arrangements through the Supreme Court’s official electronic-notarization resources before paying or uploading sensitive documents.

Is notarization required for every affidavit or contract?

Not every private agreement must be notarized to be valid. Philippine law generally recognizes contracts in whatever form they are entered into, provided their essential requisites are present, unless the law requires a particular form for validity, enforceability, proof, registration, or effect against third persons.

Notarization can nevertheless be legally or practically important because it may:

satisfy a statute, rule, court, agency, or contractual requirement;
authenticate the execution of an instrument;
convert a qualifying private document into a public document for evidentiary purposes;
permit registration or recording; or
provide a formal record of the transaction.

The exact consequence of a missing or defective notarization depends on the document. For some transactions, the underlying agreement may remain valid between the parties but be unenforceable, unregistrable, or ineffective against third persons until the required form is satisfied. Other documents may fail to comply with a mandatory statutory or procedural requirement.

What notarization proves—and what it does not

Proper notarization gives a document the evidentiary character accorded to a public document, but it does not automatically prove that every factual statement in it is true.

Notarization ordinarily authenticates the notarial act: appearance, identity, execution or acknowledgment, and, for a jurat, the administration of an oath or affirmation. It does not:

cure false statements;
establish ownership that the signer did not have;
validate an illegal transaction;
supply missing corporate or representative authority;
eliminate fraud, forgery, incapacity, mistake, or undue influence;
guarantee that a court or agency will accept the document for its intended purpose; or
replace substantive evidence required to prove the facts stated.

An affidavit offered in court may still be subject to the Rules on Evidence, procedural rules, cross-examination requirements, and objections such as hearsay. A judicial affidavit is governed by the Judicial Affidavit Rule and involves requirements beyond ordinary notarization.

Special situations

The affiant cannot sign normally

A person who cannot sign may, where legally permissible, use a thumbmark or another mark. The circumstances, witnesses, certificate, and method of execution must comply with the applicable notarial rules and any special law governing the document. Arrange this with the notary in advance.

The affiant is elderly, ill, or has a disability

Age, illness, or disability does not by itself prevent a person from executing an affidavit. The central issues are identity, understanding, voluntariness, communication, and compliance with the required formalities. The notary may seek additional safeguards or refuse if capacity or voluntariness cannot be responsibly established.

The document will be used abroad

Ask the foreign recipient what it requires. Philippine notarization alone may not be sufficient. The document may also require an apostille from the Department of Foreign Affairs or, for a destination outside the Apostille Convention framework, another form of authentication or legalization. Translation and destination-country requirements may also apply.

The affidavit was executed abroad

An affidavit made outside the Philippines should ordinarily be sworn before a Philippine consular officer or another locally authorized officer, followed by any authentication or apostille required for Philippine use. The proper route depends on the country of execution, the receiving authority, and the document’s purpose.

The affiant is a minor

A minor’s ability to execute a particular affidavit depends on the subject, the minor’s capacity to understand the statements, and the governing law or agency procedure. Parental consent or participation may be required for the underlying transaction, but a parent should not impersonate the child as affiant. Ask the receiving authority and the notary what form is legally appropriate.

Evidence to preserve

Keep:

the notarized original or a secure certified or authenticated copy;
clear copies of every page and annex;
proof of the identification document presented;
receipts and official communications from the notary or electronic-notarization facility;
the notary’s name, commission details, office address, document number, page number, book number, and series year;
drafts showing who supplied or changed material statements;
proof of signing authority, if applicable; and
messages, travel records, or other evidence of personal appearance if the notarization is later questioned.

Do not alter the notarized document, replace pages, detach annexes, or reuse the notarial certificate for another document.

Common mistakes

Treating a cedula as sufficient identification.
Signing an affidavit outside the notary’s presence when a jurat is required.
Sending another person to have the document notarized.
Leaving blanks for names, amounts, dates, property descriptions, or material terms.
Using an acknowledgment when an oath or jurat is legally required.
Assuming notarization proves the truth of every allegation.
Using an expired, damaged, or unverifiable ID.
Failing to attach or properly identify documents referred to as annexes.
Using a notary outside the territorial scope of the notarial commission.
Assuming any lawyer is automatically authorized to notarize.
Paying an online service without confirming that the provider and electronic notary operate under the Supreme Court’s official framework.
Making post-notarization corrections without re-execution.
Signing an affidavit without reading it because someone else prepared it.

What to do if a notarization appears fraudulent

If your signature was forged, you never appeared before the stated notary, or the document was altered:

Secure a complete copy of the questioned document.
Preserve specimens of your genuine signature and records showing where you were on the alleged notarization date.
Note the document, page, book, and series numbers in the notarial certificate.
Request verification from the Office of the Clerk of Court of the Regional Trial Court that commissioned the notary, subject to its procedures.
Obtain relevant registry, land, corporate, bank, or agency records before they are changed or lost.
Consult counsel promptly about civil, criminal, administrative, registration, or injunctive remedies.
If property or funds are about to be transferred, ask immediately whether a temporary restraining order, injunction, adverse claim, notice of lis pendens, account hold, or another protective measure is legally available.

Do not confront suspected perpetrators in a way that risks evidence destruction or personal harm.

When legal help is urgent

Seek prompt legal assistance when:

the affidavit will be used in a pending case with a filing deadline;
a false affidavit has resulted in an arrest, charge, dismissal, transfer of property, or loss of money;
a deed, power of attorney, waiver, settlement, or mortgage was allegedly notarized without your appearance;
the affiant may lack capacity or is allegedly being coerced;
land, shares, bank funds, inheritance, or company assets may be transferred;
a government agency has rejected the document;
an affidavit contains a material error after filing;
you are being asked to swear to facts you do not personally know or believe to be true; or
the document will be used abroad and authentication deadlines are approaching.

Frequently asked questions

Can I bring an affidavit that is already signed?

For a jurat, the affiant should sign in the notary’s presence after taking the oath or affirmation. If the document was signed beforehand, the notary may require a fresh signature or re-execution. An acknowledgment follows different rules, but personal appearance remains necessary.

Can a relative take my affidavit to the notary?

No, not for conventional notarization in your name. The affiant’s personal appearance cannot be delegated.

Is one valid government ID enough?

The governing rule generally refers to at least one current official identification document bearing the holder’s photograph and signature. A notary may reasonably request another ID or supporting proof if identity remains uncertain.

Can the notary prepare my affidavit?

A lawyer may draft a document as a legal service, but drafting and notarization are distinct functions. The affiant remains responsible for truthfully reviewing and adopting the statements. Conflicts, prohibited interests, and professional duties must be observed.

Does an affidavit expire?

An affidavit does not ordinarily have a universal statutory expiration date. Its usefulness may depend on how current its facts are and on the receiving agency’s rules. Some offices require affidavits executed within a stated period.

How much does notarization cost?

There is no single fee applicable to every document and locality. The charge may depend on the notarial act, document, location, professional service involved, and any applicable local or office schedule. Ask for the fee before proceeding and request a receipt where appropriate.

Can I notarize a photocopy?

A photocopy cannot simply be treated as an original affidavit. Whether a copy may be certified, authenticated, or accepted depends on the type of document, the notary’s authority, and the receiving institution’s rules. Bring the original for examination whenever available.

Can ordinary online notarization replace personal appearance?

Only a process that complies with the Supreme Court’s Rules on Electronic Notarization may use authorized electronic appearance. A private video call, scanned signature, or emailed PDF is not a substitute.
