Quick answer

A Philippine affidavit is a written statement of facts made under oath or affirmation. For an ordinary paper affidavit, the affiant must generally:

Use the correct form required for the transaction, case, or government application.
Complete the document without material blanks.
Personally appear before a duly commissioned notary public.
Prove identity through competent evidence of identity.
Sign the affidavit in the notary’s presence.
Swear or affirm that its contents are true.
Receive a completed jurat bearing the notary’s signature, seal, commission details, and notarial-register information.

Sending a signed affidavit and photocopied ID through a relative, courier, or messenger is not valid personal appearance. An ordinary video call is also insufficient. Remote notarization is lawful only for electronic documents processed by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility under the 2025 Rules on Electronic Notarization.

These are the general rules. Courts, prosecutors, embassies, banks, schools, employers, and government agencies may prescribe additional wording, attachments, witnesses, filing periods, or document-validity periods.

What notarization does—and does not do

A valid notarization confirms that the required person appeared, was properly identified, and performed the act stated in the notarial certificate.

Regular notarization generally gives a private document public character and a presumption of regularity concerning its execution. It does not:

prove that every factual statement is true;
confirm ownership, authority, or the authenticity of attached records;
cure an illegal, fraudulent, or legally defective transaction;
replace a required court appearance or testimony;
guarantee that an agency, court, or foreign government will accept the document; or
substitute for registration, apostille, taxation, or other procedures required by law.

A defective notarization can strip a document of its public character and reduce it to a private document requiring separate proof of authenticity. Whether the underlying act remains valid depends on the law governing that particular transaction. The Supreme Court explains this distinction in Requina v. Puno.

An affidavit normally requires a jurat

The correct notarial act for an affidavit is ordinarily a jurat, not an acknowledgment.

Notarial act	What the signer does
Jurat	Appears, signs in the notary’s presence, and takes an oath or affirmation concerning the document
Acknowledgment	Appears and declares that an existing signature was voluntarily affixed and that the document is the signer’s free act or deed
Signature witnessing	Appears and signs in the notary’s presence, without necessarily swearing to the contents
Copy certification	Presents an eligible original for copying and comparison by the notary

An acknowledgment is commonly used for contracts and deeds. A jurat is used for affidavits because the affiant is swearing to the truth of the statements.

A notary’s copy-certification power is limited. The notary may not use it for a vital record, public record, or publicly recordable document. For a birth, marriage, or death certificate, obtain the appropriate certified copy from the Philippine Statistics Authority or official custodian instead of asking a private notary to “certify” a photocopy.

Requirements for the affidavit itself

There is no single universal affidavit template. The proper contents depend on its purpose, but a usable affidavit ordinarily includes:

the affiant’s complete legal name and relevant personal details;
a clear identification of the affidavit’s purpose;
facts stated in numbered paragraphs and, where possible, in chronological order;
only facts the affiant can truthfully swear to, with sources identified when information is not based on personal observation;
correct names, dates, addresses, amounts, document numbers, and property descriptions;
a clear description of any attachment, with attachments consistently marked;
the affiant’s signature;
the place and actual date of execution; and
a complete jurat.

Use the exact official form when the receiving office provides one. An affidavit for loss, discrepancy, support, consent, employment, service, adverse claim, estate settlement, criminal complaint, or court testimony may have requirements that a generic form does not satisfy.

Do not leave material blanks for later completion. The 2004 Rules on Notarial Practice prohibit notarization of a blank or incomplete document and prohibit a notary from signing or sealing an incomplete notarial certificate.

Personal appearance is mandatory

For a traditional paper affidavit, the affiant must physically appear before the notary at the time of notarization. The affiant must personally sign in the notary’s presence and take the oath or affirmation.

The following do not satisfy that requirement:

a relative or employee bringing the signed document;
leaving documents and IDs at a notarial office for later pickup;
emailing a scanned signature;
signing at home and merely confirming the signature by telephone;
sending a video of the signing; or
using an ordinary Zoom, Messenger, or similar call outside the electronic-notarization system.

The Supreme Court has repeatedly treated personal appearance and proper identification as fundamental safeguards against forgery and impersonation. See Ladrera v. Rubiano.

A traditional notary ordinarily performs notarial acts at the notary’s regular office and within the territorial jurisdiction of the commissioning court. Limited off-site notarization is permitted in specified circumstances, such as at certain public functions, hospitals where a party is confined, or places of detention, provided the location remains within the notary’s jurisdiction.

What identification should the affiant bring?

The general rule is competent evidence of identity: at least one current identification document issued by an official agency and bearing the person’s photograph and signature. A notary may require additional proof when names, signatures, photographs, dates of birth, or other details are inconsistent.

Bring, when available:

the original current government-issued photo ID;
a second ID or supporting record if the name or signature differs;
the document explaining a name change, such as a marriage certificate or court order; and
originals or official copies of records referred to in the affidavit.

There is no general “two-ID rule” in the 2004 Rules, although a receiving agency or a notary addressing a genuine identity issue may require more documentation.

The National ID—whether in card, paper, or digital form—is official proof of identity under Republic Act No. 11055, subject to proper authentication. The PSA confirms that the Digital National ID is sufficient proof of identity and age. Because the National ID deliberately has no handwritten signature, bringing another signature-bearing ID may prevent delay when signature comparison is material, but it should not be presented as a universal legal requirement.

A community tax certificate or cedula alone is not competent evidence of identity under the current notarial standard. A birth certificate also does not ordinarily establish the present identity of the person appearing because it lacks a current photograph and signature.

The Rules provide a credible-witness alternative in defined circumstances. Depending on whether the witnesses are personally known to the notary, one or two credible witnesses may be required. They must personally know the affiant, must not be parties or beneficiaries of the transaction, and may themselves need documentary identification. Arrange this directly with the notary before the appointment.

What should appear in the jurat?

Before leaving, confirm that the jurat is complete and consistent with what actually occurred. It should ordinarily show:

the proper venue or place of notarization;
the actual date the affidavit was subscribed and sworn to;
the affiant’s identity and the evidence used to establish it;
the notary’s signature and official seal;
the notary’s name, office address, commission number, jurisdiction, and commission-expiry details;
the notary’s Roll of Attorneys and other required professional details; and
the document, page, book, and series numbers corresponding to the notarial register.

Never ask a notary to backdate the jurat. If a material error is discovered after notarization, do not erase, replace pages, or quietly alter the original. Ask whether the affidavit must be corrected, re-executed, and notarized again.

A lawyer is not automatically authorized to notarize. The lawyer must have a current notarial commission for the relevant jurisdiction. A document notarized under an expired or nonexistent commission may lose the benefits of proper notarization.

Persons who cannot sign in the usual way

The Rules provide alternatives for a person who is physically unable to sign.

A thumbmark or other mark may be used if it is affixed in the presence of the notary and two disinterested and unaffected witnesses. The witnesses must sign, and the notary must include the certification required by the Rules.

If the person cannot sign or make a mark, the notary may sign at that person’s direction, again in the presence of two disinterested and unaffected witnesses and using the prescribed certification.

These procedures address physical inability, not lack of understanding or consent. A notary must refuse when there is reasonable doubt that the person understands the transaction or is acting freely. If illness, disability, medication, coercion, or impaired capacity may be disputed later, obtain legal advice before execution and preserve relevant medical and witness evidence.

Conflicts, language, and free consent

A notary must not notarize a document when the notary:

is a party to the document;
will obtain a prohibited direct or indirect interest from the transaction; or
is the principal’s spouse, common-law partner, ancestor, descendant, or relative by blood or marriage within the fourth civil degree.

The affiant must understand the affidavit and the consequences of signing it. If the document is in a language the affiant or notary does not understand, arrange an accurate translation or qualified interpreter and confirm the receiving office’s requirements. The notary may refuse if the transaction appears unlawful or immoral, the signer does not appear to understand its consequences, or the signer is not acting voluntarily.

Electronic and remote notarization

The 2025 Rules permit electronic notarization of electronic documents through:

In-Person Electronic Notarization, where the principal physically appears before an Electronic Notary Public; and
Remote Electronic Notarization, where the appearance occurs through the accredited facility’s live videoconferencing system.

The document must be in the required PDF or PDF/A format and processed through a Supreme Court-accredited Electronic Notarization Facility. The Electronic Notary Public must hold the proper commission. A typed name, pasted image of a signature, ordinary e-signature platform, or private video call does not by itself produce an electronically notarized affidavit.

For remote electronic notarization, the participants must generally be within the Philippines. A principal abroad may use the special exception only while within the premises of a Philippine embassy, consular office, or Philippine honorary consul’s office and after the required location verification.

The electronic rules do not cover notarial wills or deposition-taking. Paper documents bearing wet signatures or marks remain governed by the 2004 Rules. Current implementation information and participating services should be checked through the Supreme Court’s eNotary Services portal and official eNotarization FAQ.

Affidavits executed abroad

A person outside the Philippines should first ask the Philippine receiving office which route it accepts. Common options include:

execution before a Philippine embassy or consulate, following that post’s personal-appearance and identification rules; or
execution before an authorized notary in the foreign country, followed by an apostille or other authentication when required.

An apostille is different from notarization. It authenticates the origin of the public document or notarial certification for international use; it does not certify that the affidavit’s factual contents are true. Requirements vary according to the issuing country, destination country, and receiving institution.

For Philippine private documents intended for use abroad, the DFA states that private documents can be authenticated only after notarization. Check the current document-specific requirements, appointment system, and destination-country rules through the DFA’s Apostille portal.

Deadlines and “validity periods”

An affidavit has no universal expiration period merely because it was notarized. Its practical acceptability depends on:

the governing statute, regulation, or court rule;
the receiving office’s written requirements;
whether the affidavit’s facts remain current;
a deadline stated in the document or application; and
whether a recent execution date is required.

For example, the Judicial Affidavit Rule generally requires judicial affidavits and attachments to be filed and served not later than five days before the relevant pre-trial, preliminary conference, or scheduled hearing, subject to the rule’s conditions and the applicable court order. An ordinary affidavit is not automatically a compliant judicial affidavit.

Do not assume an old affidavit remains truthful after circumstances change. A change in address, marital status, employment, ownership, loss status, authority, or supporting records may require a new affidavit even when no fixed expiration period exists.

False affidavits and other consequences

An oath is not a formality. Knowingly making a material false statement in an affidavit before a competent officer, when the affidavit is required by law or made for a legal purpose, may constitute perjury if all legal elements are established. Republic Act No. 11594 substantially increased the criminal penalties for perjury and provides additional consequences in specified cases. See the official text of Republic Act No. 11594.

Depending on the conduct involved, forgery, falsification, fraud, obstruction, administrative liability, civil damages, or case-specific sanctions may also arise. An honest mistake is not automatically perjury, but a material error should be corrected promptly and transparently.

Notarization also does not guarantee that an affidavit alone proves its contents in court. Affidavits are generally treated as hearsay when offered to prove their assertions without the affiant’s testimony and an opportunity for cross-examination, unless an applicable rule or exception permits their use. The Supreme Court discusses this principle in People v. Parba-Rural.

Practical step-by-step checklist

Before the appointment

Obtain the latest official form and written requirements from the receiving office.
Confirm whether it needs an affidavit, acknowledgment, judicial affidavit, consular notarization, or apostille.
Check the submission deadline and any required recency period.
Verify every material fact against original records.
Arrange paragraphs chronologically and identify attachments accurately.
Resolve name, date, address, and signature discrepancies.
Remove material blanks or mark genuinely inapplicable fields as the form directs.
Bring current identification and supporting originals.
Arrange qualified witnesses or an interpreter when required.
Do not sign a paper affidavit in advance.

During notarization

Appear personally and present the complete affidavit.
Show the required identity evidence.
Review every page before signing.
Sign in the notary’s presence.
Take the oath or affirmation.
Make sure any necessary witnesses sign in the required manner.
Confirm that the notary enters the transaction in the notarial register.

Before leaving

Inspect the jurat, seal, date, commission details, and register numbers.
Check that all pages and attachments belong to the same affidavit.
Obtain the notarized original and any copies needed for filing.
Ask for a receipt and clarify whether drafting or other professional services were charged separately.
Scan the entire completed document, including attachments and notarial pages.

Evidence worth preserving

Keep the following securely:

the original notarized affidavit;
a clear scan of every page and attachment;
the records used to verify the factual statements;
earlier drafts showing legitimate corrections;
the notary’s name, office address, commission details, and register numbers;
receipts, appointment confirmations, and communications concerning execution;
witness and interpreter details, when applicable; and
the electronic certificate, audit trail, validation data, and final PDF for an electronic notarization.

If notarization is later disputed, do not write on, staple new pages to, or otherwise alter the original. The Office of the Clerk of Court for the commissioning Regional Trial Court may be able to verify the notary’s commission and relevant official records. A lawyer can determine which certification or record request is appropriate.

Common mistakes to avoid

Using a generic online template without checking the receiving office’s form.
Signing before meeting the notary when a jurat is required.
Allowing another person to bring the document for notarization.
Treating a cedula as sufficient identification.
Leaving amounts, dates, names, or factual paragraphs blank.
Attaching documents that are not identified in the affidavit.
Using inconsistent names or dates across the affidavit, IDs, and attachments.
Swearing to another person’s conclusions without identifying the source.
Changing or replacing pages after notarization.
Assuming a notarial seal proves that the underlying statements are true.
Using an uncommissioned, expired, or out-of-jurisdiction notary.
Treating a private video call or e-signature as remote notarization.
Waiting until the filing deadline to resolve identity, capacity, or overseas-execution issues.

When legal help is urgent

Seek prompt advice from a Philippine lawyer when:

a court, prosecutor, immigration, election, tax, or regulatory deadline is near;
the affidavit concerns criminal accusations or could expose someone to criminal liability;
you are being pressured to sign statements you do not understand or believe to be false;
a signature, seal, identity, or notarial entry appears forged;
the affiant supposedly appeared in the Philippines but was abroad on the stated date;
the affidavit affects land, inheritance, corporate authority, substantial debt, or family rights;
capacity, coercion, disability, or translation may be disputed;
pages were added or altered after notarization;
an agency rejected the document for a curable defect; or
the document must be used abroad and the correct consular or apostille route is unclear.

Preserve the document and surrounding evidence before confronting a suspected forger or arranging a replacement.

Frequently asked questions

Can I sign the affidavit before going to the notary?

Generally, no. A jurat requires the affiant to sign in the notary’s presence and take an oath or affirmation. Acknowledgments follow a different rule, but an affidavit normally uses a jurat.

Are two valid IDs always required?

No. The general rule refers to at least one current official identification document bearing a photograph and signature. A second ID may be requested to resolve a discrepancy or under the receiving office’s separate requirements.

Can someone else have my affidavit notarized for me?

No. The affiant’s personal appearance, identification, signature, and oath cannot be delegated to a relative, assistant, lawyer, or messenger.

Is online notarization legal?

Yes, but only under the Supreme Court’s electronic-notarization framework. The document must be electronic and processed by a commissioned Electronic Notary Public through an accredited facility. An ordinary video call is not enough.

How long is a notarized affidavit valid?

There is no universal period. The applicable agency, court, transaction, or statute may require a recently executed affidavit, and changed facts may make an older affidavit inaccurate.

Does a notarized affidavit automatically win or prove a case?

No. Notarization concerns execution and authenticity, not the ultimate truth or legal sufficiency of the statements. Admissibility, evidentiary weight, and the need for testimony depend on the governing procedural and evidence rules.

Can a notary refuse to notarize my affidavit?

Yes. A notary should refuse a blank or incomplete document, inadequate identification, unlawful or suspicious transaction, lack of personal appearance, apparent coercion, or circumstances creating reasonable doubt about the signer’s understanding or free will.

Can a notary certify a photocopy of my PSA certificate?

Not through ordinary notarial copy certification. Vital and public records are excluded. Obtain an official certified copy from the proper issuing agency or custodian.
