Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. For a paper affidavit in the Philippines, the affiant must ordinarily:

Bring a complete document with no material blanks.
Personally appear before a duly commissioned notary public—or another officer specifically authorized by law to administer the oath.
Prove identity through competent evidence.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its material statements are true.

The notary then completes the jurat, signs and seals it, and records the act in the notarial register. A cedula or community tax certificate alone is not competent proof of identity. An ordinary video call, emailed scan, or “online notary” is also insufficient unless the process complies with the Supreme Court’s Rules on Electronic Notarization.

Not every document needs notarization. The governing law, required form, court rule, contract, or receiving agency determines whether an affidavit, acknowledgment, witnesses, attachments, or additional authentication is required. Notarization establishes the regularity of the oath or execution; it does not automatically prove that every statement is true, transfer ownership, cure an illegal agreement, or replace registration and tax requirements.

Affidavit, jurat, and acknowledgment are different

Document or act	What the signer declares	Must the signer appear?	Must signing occur before the notary?
Affidavit with jurat	The statements are true under oath or affirmation	Yes	Yes
Acknowledged instrument	The signature was voluntarily affixed and the document is the signer’s free act or deed	Yes	Not necessarily; an earlier signature may be acknowledged personally
Signature witnessing	The signature is affixed before the notary	Yes	Yes
Unsworn statement	No oath is administered	Not an affidavit merely because it is signed	Not unless another rule requires it

A jurat normally begins with wording such as “Subscribed and sworn to before me.” It is the proper notarial act for an affidavit. An acknowledgment is commonly used for deeds, contracts, powers of attorney, and other instruments in which the signer confirms voluntary execution.

Using an acknowledgment where an oath and jurat are required may make the filing defective. Conversely, adding “sworn” language does not repair a document if no oath was actually administered.

What a proper affidavit should contain

The required contents depend on its purpose, but a sound affidavit normally includes:

The correct venue, such as the Republic of the Philippines and the city or province where the oath is administered.
A descriptive title.
The affiant’s full legal name, age or legal capacity where relevant, civil status if material, nationality if required, and complete address.
A clear statement that the affiant is competent to testify and is stating facts from personal knowledge.
Separately numbered factual paragraphs in chronological order.
Exact names, dates, places, document numbers, amounts, and descriptions supported by records.
The purpose for which the affidavit is executed.
Properly identified attachments, such as “Annex A,” with no missing pages.
The affiant’s signature over printed name.
A complete jurat stating the date and place of the oath and how identity was established.

Do not copy a generic template without checking the receiving office’s prescribed form. Affidavits for civil registration, immigration, employment, marriage, land registration, corporate transactions, court proceedings, and administrative cases can have different mandatory statements and supporting documents.

State only facts personally known to you. If information comes from a record, identify the record and explain your basis for relying on it. Do not present assumptions, legal conclusions, or another person’s account as firsthand knowledge.

Paper notarization: what to do

1. Confirm the exact requirement

Ask the receiving court, agency, bank, school, employer, insurer, or other institution for:

Its current form and checklist.
The number of originals and photocopies.
Required attachments and witnesses.
Whether a jurat, acknowledgment, or another certification is needed.
Its filing deadline and any stated period of validity.
Whether it accepts electronic notarization or requires a paper original.
Whether a document executed abroad needs an Apostille or other authentication.

There is no single nationwide filing deadline or expiration period for all affidavits. A receiving institution may reject an affidavit that is too old, does not cover current facts, or misses a proceeding-specific deadline.

2. Finish the document before notarization

Correct names, dates, addresses, annex references, page numbering, and material terms before appearing. The 2004 Rules on Notarial Practice, as amended prohibit notarization of a blank or incomplete document or one without an appropriate notarial certificate.

For a jurat, do not sign in advance. Every affiant in a joint affidavit must personally complete the required appearance, identification, signing, and oath.

3. Use a properly commissioned notary

A traditional notary’s authority is limited to the territorial jurisdiction of the court that issued the commission. The act is ordinarily performed at the notary’s regular place of work or business, subject to the limited locations allowed by the Rules.

Check that the office displays the notary’s commission and fee schedule. If authenticity matters—particularly for land, estate, corporate, or high-value documents—verify the commission with the Office of the Clerk of Court of the appropriate Regional Trial Court.

4. Bring competent proof of identity

The general paper-notarization rule requires at least one current identification document issued by an official agency bearing the holder’s photograph and signature. Illustrative examples include:

Passport.
Driver’s license.
PRC ID.
NBI or police clearance meeting the required features.
Voter’s ID.
GSIS e-card, SSS card, or qualifying government office ID.
Senior citizen ID.
OWWA or OFW ID.
Seaman’s book.
Alien Certificate of Registration.
Other current official identification satisfying the rule.

The list is not exclusive, but the ID must meet the rule’s features and must enable the notary to establish identity. Bring an alternative qualifying ID if the document you intend to use lacks a visible signature or is difficult to authenticate.

A cedula or community tax certificate alone is insufficient because it does not bear the required photograph and signature. The Supreme Court applied this rule in Heir of Unite v. Atty. Guzman and emphasized that the ID used should be reflected in the notarial record. See the 2008 amendment on competent evidence of identity and the Supreme Court decision.

If the affiant has no qualifying ID, the Rules allow identification through:

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, each personally knows the affiant, and each presents documentary identification.

A notary who genuinely knows the affiant personally may use personal knowledge, but casual introduction, a cedula, or the phrase “known to me” should not be treated as a substitute for the rule.

5. Appear, sign, and take the oath

The notary must see the affiant, inspect the document and identification, witness the signing for a jurat, and administer an actual oath or affirmation. The affiant must also sign or place the appropriate mark in the notarial register.

A messenger, relative, office employee, or attorney-in-fact cannot take the affiant’s oath. A representative executing a document must sign in the representative’s own capacity, personally appear, and present proof of authority where required.

6. Inspect the completed notarization

Before leaving, check that:

No pages or attachments were changed or omitted.
The date and place are correct.
The jurat or acknowledgment is complete.
The type and details of the ID are recorded where required.
The notary signed by hand and affixed a legible official seal.
The commission number, commission expiry, office address, Roll of Attorneys number, PTR details, and IBP details appear in the certificate.
The document, page, book, and series references are filled in.
You received the proper receipt for fees charged.

Do not accept an undated certificate, blank notarial details, a loose seal supplied without the notary, or a promise that staff will “have it notarized later.”

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, effective in 2025, supplement rather than replace traditional paper notarization. They govern electronic documents in PDF or PDF/A format and authorize:

In-person electronic notarization, where the principal physically appears before an Electronic Notary Public but signs or confirms an electronic document through the approved system.
Remote electronic notarization, where the required appearance and notarial acts occur through a compliant real-time videoconference and other prescribed identity and security controls.
A permitted hybrid arrangement where applicable under the Rules.

Electronic notarization must be performed by a separately commissioned Electronic Notary Public using a Supreme Court-accredited Electronic Notarization Facility. The system performs prescribed identity verification, authentication, geolocation, signing, recording, certificate, and audit functions. A prerecorded signing video is prohibited.

The electronic rules do not apply to:

Paper documents bearing wet signatures or marks.
Notarial wills.
Deposition taking.

For a principal located abroad, remote electronic notarization is permitted only under the Rules’ limited conditions, including that the Electronic Notary Public is in the Philippines and the principal is within the premises of a Philippine embassy, consular office, or office of a Philippine Honorary Consul.

Check the Supreme Court’s eNotary Services page and accredited-facility directory before paying any provider. A commercial platform’s claim that it offers “online notarization” is not enough.

The electronic copy you should receive after paper notarization

Under the 2025 amendments to the traditional rules, a notary must transmit to each signatory, at no additional cost, an electronic copy of the duplicate original through email or another mutually agreed electronic file-sharing method. The rule states that transmission must occur within five days from completion of the notarial act or from the applicable deadline for transmitting the duplicate original to the Clerk of Court.

A signatory may waive electronic transmission, but the waiver also waives objections to the completeness of the reproduction. Do not waive it casually. Compare the electronic copy immediately with the paper document. If a material discrepancy affects anyone’s rights, notify the notary promptly in writing and request correction. Preserve the message and both versions.

Special situations

A person who cannot write or sign

A thumbmark or other mark may be notarized if it is affixed in the presence of the notary and two disinterested, unaffected witnesses. Both witnesses must sign, and the notary must make the prescribed notation.

If the person is physically unable to sign or make a mark, the notary may sign on that person’s behalf only upon the person’s direction and in the presence of two disinterested, unaffected witnesses, with the prescribed signatures and notation.

These accommodations do not remove the requirements that the person understand the document and act voluntarily.

A person who does not understand the document

The notary must refuse if the signer’s behavior creates reasonable doubt about their understanding of the transaction’s consequences or if the signer is not acting freely. Use a document in a language the affiant understands or obtain an accurate translation where required. A relative should not pressure, coach, or answer in place of the affiant.

Corporate or representative signing

A corporate officer, guardian, executor, administrator, trustee, or attorney-in-fact may need to present the power of attorney, board resolution, secretary’s certificate, court appointment, or other instrument establishing authority. The affidavit or acknowledgment must accurately identify the representative capacity.

Documents signed abroad

A person abroad may execute the affidavit before an appropriate Philippine embassy or consulate, subject to that post’s appointment, identification, copy, and fee requirements. Alternatively, a document notarized under foreign law may need an Apostille from the competent authority of an Apostille Convention country, or authentication under the procedure applicable to a non-Convention country.

Requirements depend on the country and receiving Philippine office. Consult the relevant Philippine foreign service post and the DFA’s Apostille documentary requirements before signing.

Court affidavits

An ordinary affidavit is not automatically a compliant judicial affidavit. Under the Judicial Affidavit Rule, a judicial affidavit must contain prescribed questions and answers, witness information, identification of exhibits, a jurat, and the examining lawyer’s sworn attestation.

The general filing deadline is not later than five days before the pre-trial, preliminary conference, or scheduled hearing for motions and incidents. Criminal-case provisions contain additional rules, including a possible 10-day period for the accused’s affidavits after receiving the prosecution’s affidavits. Missing a deadline may result in waiver, subject only to the Rule’s limited relief and possible fine.

What notarization does—and does not do

Regular notarization converts a private document into a public document for evidentiary purposes and gives rise to a presumption of due execution and authenticity. But the Supreme Court has clarified that notarized documents are generally prima facie evidence of due execution and authenticity, not the truth of everything written in them. See Anido v. People, G.R. No. 253527.

A defective notarization ordinarily strips the document of its public character and leaves it to be treated as a private document. That does not always invalidate the underlying transaction. The result depends on whether the law requires a public instrument merely for convenience or enforceability, or as an indispensable condition of validity.

For example, the Civil Code requires a donation of immovable property and its acceptance to comply with Article 749’s public-document formalities for validity. Other contracts may remain valid between the parties despite defective or absent notarization, although proof, registration, and enforcement can become more difficult.

Notarization also does not:

Register a deed with the Registry of Deeds.
Transfer title by itself.
Establish that the signer owned the property.
Supply missing consent, authority, witnesses, or statutory language.
Pay taxes or obtain regulatory approval.
Make an unlawful agreement enforceable.
Guarantee that an affidavit will be admitted or believed in court.

Affidavits offered to prove their contents in a trial may still be excluded as hearsay unless the affiant testifies and is available for cross-examination, subject to the Rules of Evidence and recognized exceptions. Administrative and summary proceedings may apply different evidentiary rules.

Perjury and other consequences of false statements

A false statement does not become true because a notary applied a seal. Perjury under Article 183 of the Revised Penal Code requires, among other elements, a knowingly and deliberately false assertion about a material matter, made under oath before an authorized person, where the sworn statement is required by law or made for a legal purpose.

As amended by Republic Act No. 11594, Article 183 prescribes prision mayor in its minimum period. It provides for imposition in the maximum period when the offender is a public officer or employee and also specifies a fine of up to ₱1,000,000 and perpetual absolute disqualification from government office.

Whether a particular inaccuracy constitutes perjury depends on materiality, knowledge, intent, the purpose of the affidavit, and the evidence. False documents may also create separate criminal, civil, administrative, employment, immigration, or professional consequences.

Common mistakes to avoid

Signing an affidavit before meeting the notary.
Sending only a representative, photocopy, or photograph of the affiant.
Using only a cedula as identification.
Leaving the date, ID details, annexes, amounts, names, or notarial certificate blank.
Asking a notary to backdate or antedate the act.
Using an acknowledgment instead of the required jurat.
Copying statements the affiant does not personally know to be true.
Omitting qualifications, prior incidents, pending cases, or other material facts requested by the form.
Allowing pages or attachments to be substituted after notarization.
Treating a scanned paper document notarized over an ordinary video call as valid electronic notarization.
Assuming notarization makes a defective sale, donation, waiver, settlement, or power of attorney legally effective.
Missing the receiving office’s deadline while focusing only on notarization.
Waiving the electronic duplicate without keeping a reliable copy.
Failing to compare the emailed duplicate with the signed paper original.

Evidence to preserve

Keep the following securely:

The complete original notarized document and every annex.
The free electronic duplicate sent by the notary.
Earlier drafts showing when material changes were made.
The notary’s official receipt.
Appointment confirmations, emails, messages, and transmittal records.
The names and contact information of witnesses.
The date, time, and exact place of notarization.
Photographs or scans showing the document’s condition when received.
Electronic-notarization confirmation, certificate, audit information, and verification link or QR code.
Written notices identifying any discrepancy and the notary’s response.
Evidence showing where each signer was if forgery or false personal appearance is suspected.

Protect ID copies and other personal data. Transmit them only through the notary’s or receiving institution’s verified, secure channel.

When legal help is urgent

Consult a Philippine lawyer promptly if:

A filing deadline before a court, prosecutor, tribunal, or government agency is approaching.
The affidavit concerns a criminal complaint, counter-affidavit, arrest, detention, protection order, or alleged perjury.
You are being pressured to sign a false, incomplete, backdated, or misunderstood document.
The document transfers or waives rights involving land, inheritance, corporate ownership, loans, settlement proceeds, employment claims, or family status.
An elderly, ill, disabled, or vulnerable signer may not understand the transaction or may be under pressure.
A signature, seal, commission number, notarial entry, or electronic certificate appears forged or altered.
A notarized document supposedly bearing your signature was executed without your appearance.
A foreign or electronic document will be used for immigration, court, land, banking, or corporate purposes.

For suspected irregular notarization, preserve the original and ask the appropriate Regional Trial Court’s Office of the Clerk of Court to verify the notary’s commission and available notarial records. An interested or affected person may file a verified complaint concerning a traditional notary with the Executive Judge under the Notarial Rules. Obtain legal advice before surrendering an original document or making accusations of fraud.

Frequently asked questions

Can I sign an affidavit at home and have someone take it to the notary?

No. A jurat requires your personal appearance, signing in the notary’s presence, and oath or affirmation. Use a compliant electronic-notarization process if available and appropriate; do not substitute an ordinary video call or courier arrangement.

Is one government ID enough?

The paper rule permits at least one current official ID bearing your photograph and signature. A notary may reasonably request additional proof where identity, name discrepancies, authority, or fraud risk remains uncertain.

Is a cedula valid for notarization?

Not by itself. The Supreme Court has ruled that a community tax certificate does not satisfy the competent-evidence requirement because it lacks the required photograph and signature.

Do I need witnesses for every affidavit?

No. An ordinary affidavit does not automatically require subscribing witnesses. Witnesses may nevertheless be required by the governing law or form, to establish identity under the credible-witness procedure, or when a thumbmark or assisted signature is used.

Can the notary be my relative?

A notary is disqualified when the principal is the notary’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree. A notary who is a party to or has a prohibited interest in the transaction is also disqualified.

Does a notarized affidavit expire?

There is no universal expiration period. The receiving office may impose a freshness requirement, and an affidavit may become inaccurate when circumstances change. Check the applicable law, form, and current agency instructions.

Can a notarized affidavit alone win a court case?

No. Its weight depends on relevance, personal knowledge, admissibility, supporting evidence, credibility, and the opportunity for cross-examination. Notarization does not establish the truth of contested allegations.

Can a paper affidavit be notarized remotely?

Not under the permanent electronic-notarization rules merely by scanning it or showing it on camera. Paper documents with wet signatures remain governed by the amended traditional rules. Electronic notarization requires an electronic document, a commissioned Electronic Notary Public, and a Supreme Court-accredited facility.

How much should notarization cost?

The Notarial Rules regulate chargeable fees and require a notary who charges fees to post a schedule and issue a BIR-registered receipt. Travel expenses may be separately agreed where travel is legally permitted. The electronic duplicate sent to each signatory under the amended paper rules must be provided at no additional cost.

Can the notary correct the facts or give legal advice?

The notary may refuse an incomplete, unlawful, involuntary, or doubtful transaction, but notarization itself is not a legal review of your rights. For property, inheritance, corporate, criminal, family, immigration, or substantial financial matters, have a lawyer review the document before—not after—you sign it.
