Quick answer

An affidavit is a written statement of facts that the person making it—the affiant—swears or affirms to be true before a notary public or another officer legally authorized to administer oaths. For an ordinary paper affidavit in the Philippines, the affiant generally must:

complete and review the affidavit;
personally appear before the notary;
prove identity through acceptable evidence unless personally known to the notary;
sign the affidavit in the notary’s presence; and
take an oath or affirmation as to its contents.

A notary should not notarize an unsigned-in-advance jurat without having the affiant sign again in the notary’s presence, a document with material blanks, or an affidavit for someone who does not personally appear. Sending a signed paper by messenger—or appearing only through an ordinary video call—does not satisfy the rules for paper notarization.

Electronic notarization has a separate legal framework. It may be performed only under the Supreme Court’s Rules on Electronic Notarization, through the authorized process and by a lawyer holding the appropriate electronic notarial commission. A privately arranged video call is not automatically a valid electronic notarization.

What an affidavit must contain

The exact contents depend on the agency, court, transaction, or law requiring the affidavit. A basic affidavit ordinarily includes:

a title identifying its purpose;
the affiant’s full legal name and relevant personal details;
numbered statements of facts within the affiant’s personal knowledge;
references to supporting documents, properly identified as annexes when appropriate;
a declaration that the statements are true;
the affiant’s signature over the printed name; and
a complete jurat signed and sealed by the authorized officer.

Names, dates, addresses, identification details, property descriptions, account numbers, case numbers, and annex labels should agree with the supporting records. If a prescribed government or court form exists, use that form and follow its instructions.

An affidavit should state facts, not guesses. If a statement comes from a record rather than personal observation, identify the record. Do not sign an affidavit whose wording you do not understand or cannot honestly confirm.

Jurat versus acknowledgment

An affidavit normally requires a jurat. In a jurat, the affiant:

appears before the notary;
is identified as required by the rules;
signs the document in the notary’s presence; and
takes an oath or affirmation concerning the document.

An acknowledgment is different. It is generally used for deeds, contracts, powers of attorney, and similar instruments. The person acknowledges that they executed the complete document as their free and voluntary act and deed. A notary should use the notarial act required by the document and the governing law; attaching a jurat to a deed that requires acknowledgment does not cure the mistake.

The Supreme Court has repeatedly treated this distinction as substantive, not cosmetic. See Ladrera v. Osorio, A.C. No. 10315, January 22, 2020.

Personal appearance is the general rule for paper affidavits

Under the 2004 Rules on Notarial Practice, a paper-affidavit jurat requires personal appearance before the notary. The notary—not a secretary, clerk, fixer, or messenger—must personally perform the notarial act.

This means the notary should not:

notarize a paper affidavit merely because the affiant sent an ID and signed document;
accept an appearance made only by a representative;
certify that an absent person appeared;
allow office staff to administer the oath, sign for the notary, or affix the notarial seal; or
notarize first and ask the affiant to appear later.

The Supreme Court has consistently enforced personal appearance because it allows the notary to verify the signer, observe the signing, administer the oath, and assess whether the act is voluntary. The controlling paper-notarization rules are the 2004 Rules on Notarial Practice, as amended.

What identification is acceptable?

If the affiant is not personally known to the notary, identity must be established through competent evidence of identity. The general documentary route is at least one current identification document that:

was issued by an official agency; and
bears the holder’s photograph and signature.

The rules give examples such as a passport, driver’s license, PRC ID, SSS card, GSIS e-card, PhilHealth card, senior-citizen card, seaman’s book, alien registration document, and qualifying government-issued certifications. The list is not necessarily exclusive, but the ID must satisfy the rule’s features. The relevant 2008 amendment is in A.M. No. 02-8-13-SC.

A community tax certificate or cedula alone is generally insufficient because it does not bear both the photograph and signature required by the rule. The Supreme Court applied that rule in Torrices v. Atty. Dacudao-Guzman, A.C. No. 12062, July 17, 2018.

Bring the original current ID, not merely a photograph on a phone. A notary may request a photocopy or electronic copy for the notarial record and may seek additional identification if there is a legitimate doubt about identity.

If the affiant has no qualifying ID

The rules provide a credible-witness method, subject to strict conditions:

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 privy to, the document or transaction. Because the precise requirements matter, arrange this with the notary beforehand rather than bringing an informal “character witness” without notice.

Prepare the document before going to the notary

Bring:

the complete affidavit;
all original annexes or supporting records needed to verify its contents;
a current official ID bearing your photograph and signature;
the number of copies required by the receiving office;
any agency checklist, prescribed form, case caption, or filing instruction; and
credible witnesses and their IDs, if the rules permit and the notary has agreed to use that identification method.

Do not leave material facts, names, dates, amounts, property descriptions, or annex references blank. Minor clerical spaces that the notary directs you to complete should be filled before the notarial act. Never permit anyone to alter a notarized affidavit afterward. If a material correction is necessary, prepare and execute a corrected or supplemental affidavit as appropriate.

The notarial certificate should be complete. For a paper notarization, it ordinarily shows the place and date of notarization, the notary’s signature and seal, commission details, and the document’s notarial-register particulars. The identity information recorded should correspond to the evidence actually presented.

Language, understanding, and voluntary execution

An affiant should understand both the language and the legal effect of the affidavit. Tell the notary if you:

cannot read the document;
do not understand the language used;
need an interpreter;
have difficulty signing;
are being pressured to sign; or
have a condition affecting your ability to understand or communicate.

The notary must decline an improper act, including where the document or transaction appears unlawful, false, incomplete, or beyond the signer’s capacity or free will. Translation, interpretation, witnesses, or additional formalities may be necessary depending on the document and the receiving authority. Do not assume that a bilingual explanation alone will meet an agency’s formal translation requirements.

Does every affidavit have to be notarized?

An affidavit is ordinarily sworn or affirmed before an authorized officer. Notarization is the usual way to accomplish this, but a particular law, court rule, or agency procedure may authorize another officer to administer the oath or prescribe a different form.

Not every written declaration is an affidavit. Some transactions accept an unsworn certification, declaration, or signed statement; others expressly demand a notarized affidavit. Follow the exact requirement of the receiving court, agency, bank, school, employer, insurer, or private party.

Notarization also does not prove that every statement in an affidavit is true. It establishes the formal notarial act and gives a regularly notarized document the evidentiary treatment accorded to a public document. A defective notarization may reduce the document to the status of a private document requiring proof of authenticity and due execution. Regular notarization may still be challenged with sufficient evidence.

Special affidavit requirements

The general rules do not replace document-specific requirements. Examples include:

Court filings

A verification, certification against forum shopping, judicial affidavit, or affidavit of service must comply with the applicable Rules of Court and any court order. A judicial affidavit has detailed content and examination requirements under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC.

Filing deadlines belong to the case or proceeding, not to notarization itself. Notarizing an affidavit does not extend a deadline or guarantee that the court will accept a late, incomplete, or improperly executed filing.

Lost documents and government applications

An affidavit of loss should accurately identify the lost item, explain lawful ownership or possession, describe when and how the loss was discovered, and state the reasonable efforts made to locate it. The receiving agency may require a particular template, police report, publication, waiting period, or additional proof. Check that agency’s current rules before signing.

Affidavits involving property, corporations, immigration, or family matters

A notarized affidavit may be only one component of a larger legal process. Land registration, estate settlement, corporate filings, support undertakings, minor-travel documents, and immigration matters can require additional signatories, documentary proof, authentication, registration, taxes, publication, or agency approval. Notarization by itself does not transfer ownership, settle an estate, confer authority, or establish legal status.

Electronic notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, provide for:

in-person electronic notarization, where the requesting party physically appears before an electronic notary; and
remote electronic notarization, where appearance and the notarial act take place through the authorized electronic system.

These rules apply to electronic documents and electronic signatures. Paper documents with wet signatures remain governed by the paper-notarization rules.

Before relying on an electronic service, verify that:

the lawyer has a valid electronic notarial commission;
the service uses the Supreme Court-authorized facility and required identity-verification process;
the particular document is eligible for electronic notarization;
every required signer can complete the prescribed appearance and signing process; and
the intended recipient accepts the resulting electronic document.

Do not treat a scanned paper, pasted image of a signature, videoconference, or emailed notarial page as valid merely because it is digital. Consult the Supreme Court’s official eNotarization information and FAQs for current implementation details.

Affidavits signed abroad

A person abroad should ordinarily use either:

a Philippine embassy or consulate authorized to perform the relevant notarial or consular service; or
a local notary or authorized officer, followed by an Apostille or other authentication when required.

For documents originating in a country that participates in the Apostille Convention, an Apostille generally replaces consular authentication, subject to the destination authority’s requirements and any country-specific exception. In a non-Apostille country, authentication or legalization may still be necessary.

Procedures, appointments, acceptable IDs, copy requirements, fees, translations, and mailing arrangements differ by post and country. Check the official website of the Philippine embassy or consulate with jurisdiction over your location. The DFA’s consular guidance illustrates the usual requirements of personal appearance, the original document, and passport identification; for example, see the official Philippine consular notarial-services guidance.

Do not assume that notarization abroad automatically makes the document usable in the Philippines—or that an Apostille validates the truth or legal sufficiency of its contents. Authentication generally verifies the origin of the public signature or seal.

After notarization: inspect and preserve the record

Before leaving, check that:

every page and annex is present;
the affidavit has no unauthorized alteration or material blank;
your name and identification details are correct;
the place and date are accurate;
the notary personally signed and affixed the proper seal;
the jurat is complete;
the document has notarial-register details; and
all copies required for filing are legible and consistent.

Keep the original safely. Make a clear scan of the complete affidavit, including the jurat, seal, annexes, and notarial details. Also preserve:

the ID used;
drafts and instructions showing the source of important facts;
receipts and appointment records;
correspondence with the notary or receiving agency;
proof and date of submission; and
any acknowledgment, tracking number, or stamped receiving copy.

For a disputed notarization, promptly preserve messages, CCTV requests, travel or location records, specimen signatures, copies of the supposed document, and information identifying the notary’s office and register entry.

Common mistakes to avoid

Signing a jurat before meeting the notary and not signing again in the notary’s presence.
Sending someone else to “process” the notarization.
Using an expired ID, a company ID without official-agency issuance, or a cedula alone.
Leaving names, dates, amounts, property details, or annexes blank.
Signing a template copied online without checking the receiving office’s required form.
Using an acknowledgment when a jurat is required, or vice versa.
Stating conclusions, hearsay, or guesses as personal knowledge.
Hiding inconsistent records from the lawyer preparing or notarizing the affidavit.
Altering, replacing, or adding pages after notarization.
Assuming notarization makes an unlawful transaction valid.
Assuming a notarized photocopy has the same effect as the original.
Paying a fixer or allowing office staff to perform the notarial act.
Treating an ordinary video call as valid remote electronic notarization.
Waiting until the filing deadline to discover that an agency requires witnesses, annexes, an Apostille, or a prescribed form.

When legal help is urgent

Consult a Philippine lawyer promptly if:

someone forged your signature or used a false notarized document involving you;
land, inheritance, a loan, corporate control, custody, immigration status, or a large financial obligation is affected;
you are being pressured to sign or surrender an original document;
an affidavit contradicts an earlier sworn statement;
police, prosecutors, courts, immigration officers, or regulators have required a sworn response;
a filing deadline, hearing, departure date, foreclosure, registration, or limitation period is near;
the affidavit may expose you or another person to criminal, civil, tax, or administrative liability;
the intended signer lacks capacity, is seriously ill, cannot appear, or is abroad; or
a notary appears to have certified a nonexistent appearance or used false register details.

If a false document threatens an immediate property transfer, withdrawal, court filing, or government action, notify the affected institution in writing and seek legal advice without delay. Preserve evidence before confronting suspected participants.

Frequently asked questions

Can I bring an affidavit that I already signed?

You may bring the draft, but for a jurat the affiant must sign in the notary’s presence. Follow the notary’s instruction, which may require a fresh unsigned copy or a new signature made in person.

Is one government ID enough?

The rule generally permits at least one current official-agency ID bearing both photograph and signature. A notary or receiving institution may reasonably require additional proof where identity is doubtful or its own lawful procedure demands it.

Is a barangay ID or certification always accepted?

Not automatically. It must meet the governing definition and enable reliable identification. Confirm in advance whether the particular document is current, officially issued, and bears the required photograph and signature.

Can a cedula be used?

A cedula alone is generally not competent evidence of identity under the current notarial rule because it lacks the required photograph-and-signature combination.

Must every page be signed?

The notarial rules do not create one universal page-signing rule for every affidavit. The prescribed form, receiving agency, contract safeguards, or notary may require initials or signatures on each page. Follow the document-specific instruction.

Does an affidavit expire?

There is no single general expiration period for all affidavits. Its usefulness may end when facts change, an agency imposes a recency requirement, or a filing deadline passes. Ask the receiving office how recent the affidavit must be.

Can any lawyer notarize my affidavit?

No. The lawyer must hold a valid notarial commission and act within the authority and territorial jurisdiction of that commission. Electronic notarization requires the corresponding electronic authority and prescribed system.

Can a relative notarize my affidavit?

The rules disqualify a notary who is the principal’s spouse, common-law partner, ancestor, descendant, or relative within the specified degrees of consanguinity or affinity. Use an independent notary to avoid invalidity and conflict concerns.

Is notarization proof that my statement is true?

No. The affiant remains responsible for the truth of the statements. Notarization authenticates the formal execution and oath; it does not independently investigate or guarantee every fact.

What happens if an affidavit contains a deliberate material falsehood?

Knowingly making a material false statement under oath for a legal purpose may constitute perjury when all legal elements are present. Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, carries serious criminal penalties. Liability depends on the exact statement, materiality, purpose, intent, and evidence.

Can a defective affidavit be corrected?

Often, the safer course is to execute a corrected or supplemental affidavit and disclose the earlier error where necessary. Do not erase, replace pages, or alter a notarized original. If it has already been filed or affects another person’s rights, obtain legal advice before submitting a replacement.
