Quick answer

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

Prepare a complete and truthful affidavit based on personal knowledge.
Bring the unsigned document, unless the receiving office’s instructions say otherwise.
Personally appear before a duly commissioned notary public.
Present acceptable proof of identity, unless personally known to the notary.
Sign in the notary’s presence and take an oath or affirmation.
Sign or place the required mark in the notarial register.
Check that the notarial certificate is complete.

A notary cannot lawfully notarize an affidavit through a messenger, based only on a photocopied signature, or after the affiant has already left. Electronic notarization is a separate procedure available only through a properly commissioned Electronic Notary Public and the authorized electronic-notarization system.

Notarization confirms the administration of the oath, the affiant’s identity and appearance, and the circumstances of execution. It does not automatically prove that every factual statement in the affidavit is true, cure false or incomplete information, establish ownership, or make an otherwise invalid transaction valid.

What an affidavit should contain

Requirements vary according to the affidavit’s purpose, but a properly prepared affidavit ordinarily contains:

A descriptive title, such as “Affidavit of Loss” or “Affidavit of Two Disinterested Persons”
The affiant’s full legal name and relevant personal details
A statement that the affiant is of legal age, or the correct age if age is material
Citizenship and address when required
Numbered paragraphs stating facts clearly and chronologically
An explanation of how the affiant personally knows those facts
Accurate identification of relevant people, dates, places, documents, and transactions
A statement of the affidavit’s specific purpose
References to attached supporting documents, properly labeled if necessary
The affiant’s signature over the printed name
A proper jurat, completed and signed by the notary or other authorized officer

Use the exact form required by the court, agency, bank, school, insurer, employer, embassy, or other recipient. A generic affidavit may be legally sworn but still rejected for omitting information required for the particular transaction.

Write in a language the affiant understands. The affiant should never swear to wording that the affiant cannot read or understand. A notary must refuse or take appropriate safeguards when the affiant appears unable to understand the document or is not acting freely.

The jurat is essential

Affidavits ordinarily require a jurat, not merely an acknowledgment.

In a jurat, the affiant:

Personally appears before the notary
Is identified through personal knowledge or competent evidence of identity
Signs the affidavit in the notary’s presence
Swears or affirms that the statements in it are true

An acknowledgment is different. It is generally used when a person declares before the notary that the person voluntarily executed an instrument as a free act and deed. It does not replace the oath required for an affidavit.

The caption “ACKNOWLEDGMENT” on an affidavit may therefore be the wrong notarial act. Conversely, changing a contract’s acknowledgment into a jurat may not satisfy a law or receiving office that specifically requires acknowledgment. The substance and purpose of the document determine the correct certificate.

Personal appearance and signing

Under the traditional paper-notarization rules, the affiant must be physically present before the notary when the notarial act is performed. The notary must personally administer the oath or affirmation and verify the affiant’s identity.

As a practical rule:

Do not send only the affidavit and ID through another person.
Do not ask a secretary, clerk, liaison, or fixer to “process” notarization without you.
Do not sign blank sheets or an incomplete affidavit.
If you signed beforehand, tell the notary. Because a jurat requires signing in the notary’s presence, the notary may require you to sign again.
Every person making the affidavit should personally appear. One affiant cannot ordinarily appear and swear for another.
Sign every place required by the document and the receiving office, including initials on corrections or each page when required.

A notarial commission is personal to the commissioned lawyer. Staff may assist with clerical work, but they cannot administer the oath, perform the notarial act, use the notary’s seal, or sign the certificate for the notary.

Acceptable proof of identity

If the notary does not personally know the affiant, the affiant must be identified through competent evidence of identity.

The general rule is at least one current identification document issued by an official agency and bearing the individual’s photograph and signature. Bring the original ID, not merely a photograph or photocopy. The notary may reasonably request additional proof where names, signatures, photographs, dates, or other details do not match.

A community tax certificate or cedula by itself is not competent evidence of identity under the current rule.

The rules also allow identification through credible witnesses in specified circumstances:

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 the required documentary identification

A relative, beneficiary, contracting party, or other person with an interest in the affidavit or transaction may not qualify as a disinterested credible witness. Ask the notary in advance before relying on this alternative.

What the notarial certificate should show

Before leaving, check that the affidavit’s jurat is not blank or incomplete. It should contain the information required for that notarial act, including the place and date of notarization and the notary’s signature and seal.

A completed paper notarization commonly displays:

The city or province stated in the venue
The date the affiant appeared and took the oath
Identification information or the manner of identification, as required
The notary’s handwritten signature and official seal
The notary’s name and commission details
The document, page, book, and series numbers corresponding to the notarial register
Other professional and commission details required by the applicable rules

Do not accept a loose stamp, an unsigned certificate, a pre-signed notarial page, or a certificate with blank dates or register details. Confirm that the affiant’s name is spelled consistently throughout the document, ID reference, signature block, and jurat.

The notarial register and document copy

For a traditional notarization, the notary records the act in an official chronological notarial register. At the time of notarization, the affiant must sign the register or affix the permitted thumbmark or other mark. Credible witnesses and witnesses to certain assisted signatures must also sign where applicable.

The Supreme Court’s 2025 amendments strengthened electronic recordkeeping and reporting for traditional notarial practice. Notaries must maintain the required PDF certified copies and make the prescribed submissions to the proper court office. These duties primarily fall on the notary, but the affiant should keep a clear copy of the final notarized affidavit and all attachments.

The notary may charge a fee but must display a complete schedule of chargeable notarial fees conspicuously in the office. There is no single nationwide private-notary price for every affidavit; cost may depend on the document and legitimate professional services involved. Ask for the fee before proceeding and request a receipt where appropriate.

When a notary must refuse

A notary should refuse to notarize when, among other reasons:

The affiant is absent
Identity cannot be established properly
The document or notarial certificate is blank or incomplete
The notary knows or has good reason to believe that the transaction is unlawful
The affiant appears not to understand the document
The affiant appears coerced, intimidated, or unable to act freely
The notary has a prohibited financial or beneficial interest
The notary is the affiant’s spouse, common-law partner, ancestor, descendant, or relative within the prohibited fourth civil degree by affinity or consanguinity
The requested act exceeds the notary’s authority or territorial commission
The affidavit contains material alterations that have not been properly addressed

A refusal does not necessarily mean that the affidavit is unlawful. The notary may simply require correction, additional identification, an interpreter, supporting records, or advice from independent counsel.

Electronic notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, establish electronic counterparts to recognized notarial acts, including an electronic jurat.

Electronic notarization is not the same as sending a scanned affidavit to an ordinary notary or taking an informal video call. It requires:

An eligible electronic document
A duly commissioned Electronic Notary Public
Compliance with the official identity-verification and appearance process
Use of the authorized electronic-notarization facility and required electronic signatures
Completion of the prescribed electronic notarial certificate and record

For an electronic jurat, the affiant must electronically sign as required in the Electronic Notary Public’s presence and take the oath or affirmation through the authorized process. The rules contemplate services for principals in the Philippines and, subject to their conditions, principals outside the country.

Implementation depends on the Supreme Court’s electronic-notarization infrastructure and commissioned providers. Confirm current availability and whether the recipient accepts an electronically notarized affidavit through the Supreme Court’s eNotarization information and FAQs. A recipient may require an original paper document, a specific electronic format, or additional authentication.

Affidavits executed outside the Philippines

A person abroad should first ask the Philippine recipient which route it accepts. Common lawful routes include:

Executing the affidavit before a Philippine embassy or consulate that provides notarial services; or
Having it notarized under the law of the foreign country and obtaining an Apostille from that country’s competent authority if the Apostille Convention applies

For a non-Apostille country, authentication or legalization requirements may apply. Some documents and destinations have special procedures or exceptions.

An Apostille authenticates the origin of the public document or notarial certification for international use. It does not certify that every factual statement in the affidavit is true. Translations, certified copies, local witnesses, or recipient-specific forms may still be required.

Check the relevant Philippine foreign service post and the Department of Foreign Affairs’ Apostille information before signing. Consular appointments, identification requirements, fees, copies, and processing arrangements vary by post and may change.

Notarization does not guarantee truth or validity

A properly notarized affidavit receives evidentiary significance as a sworn document, but notarization is not a government finding that its allegations are correct.

The Supreme Court has explained that regular notarization gives a document public character and supports a presumption concerning its due execution. Defective notarization can strip the document of that public character and reduce it to a private document. The precise legal consequence still depends on the document: many ordinary agreements may remain binding if their essential requirements are present, while transactions for which a public instrument is indispensable may fail for noncompliance with the required form.

The presumption associated with notarization principally concerns the notarial act and due execution. Courts may still reject, disbelieve, or give little weight to an affidavit because it is hearsay, conclusory, inconsistent, unsupported, outside the affiant’s personal knowledge, or contradicted by stronger evidence.

False affidavits and perjury

Never include a statement simply because someone says it is “standard.” Read every paragraph, correct every material error, and disclose uncertainty honestly.

Under Republic Act No. 11594, which amended Article 183 of the Revised Penal Code, knowingly making an untruthful statement under oath in an affidavit about a material matter may constitute perjury when the legal elements are present. The law imposes criminal penalties and provides additional consequences when the offender is a public officer or employee.

A mistake, an opinion, or a disagreement does not automatically constitute perjury. Criminal liability requires proof of the statutory elements, including a willful and deliberate material falsehood in an affidavit or sworn statement made before a competent officer for a legally required or legal purpose. Nevertheless, an inaccurate affidavit can also cause dismissal, denial of a claim, disciplinary action, civil liability, or damage to the affiant’s credibility.

If you discover a material error after notarization, do not alter the notarized document secretly. Inform the recipient promptly and ask whether to execute a corrected affidavit, supplemental affidavit, or affidavit of correction.

Purpose-specific requirements

There is no universal affidavit that works for every transaction. Examples of additional requirements include:

Court cases

A judicial affidavit is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it must follow a question-and-answer format, contain specified information and warnings, identify evidence, include the witness’s signature and jurat, and carry the examining lawyer’s sworn attestation.

Where the rule applies, parties generally file and serve judicial affidavits and attached exhibits not later than five days before pretrial, preliminary conference, or the scheduled hearing for motions and incidents. Criminal cases have additional sequencing rules. Late submission is generally treated as waived, although the court may allow it once under the rule’s stated conditions, including a valid reason, absence of undue prejudice, and payment of the prescribed fine.

Court orders, special procedural rules, and later issuances may control in a particular case. Consult counsel as soon as a court deadline is involved.

Complaints and investigations

Police, prosecutors, the NBI, the Ombudsman, administrative agencies, and regulatory bodies may require complaint-affidavits, counter-affidavits, reply-affidavits, certifications, witness affidavits, and attachments in prescribed formats and within short deadlines. Some authorized officers may administer the oath themselves.

Follow the notice, subpoena, procedural rule, or agency checklist. Ordinary notarization does not extend a filing deadline.

Affidavits of loss

State when, where, and how the item was lost, when the loss was discovered, the efforts made to find it, identifying details, and the purpose of the affidavit. A notarized affidavit does not automatically cancel a lost ID, passport, title, check, card, or certificate. Report the loss and complete the issuing institution’s separate replacement, blocking, annotation, or cancellation procedure.

Property, succession, and corporate matters

Affidavits connected with land, estates, taxes, corporate authority, beneficial ownership, or large financial transactions may require witnesses, tax records, registry forms, board approvals, publication, annotations, or separate deeds. An affidavit cannot substitute for a deed, court order, corporate resolution, or statutory process where one is required.

Affidavits involving children or vulnerable persons

Parental consent, support, guardianship, school, immigration, and travel documents are highly purpose-specific. The required signatories may include one or both parents, a guardian, witnesses, or the child, depending on the governing rule and facts. Custody orders, death certificates, proof of filiation, or evidence of sole parental authority may also be necessary.

Do not assume that one parent’s affidavit is sufficient merely because it was notarized.

Practical checklist

Before meeting the notary

Obtain the recipient’s latest official form and checklist.
Confirm the filing deadline and whether an original, certified copy, electronic document, Apostille, or consular notarization is required.
Verify all names, dates, addresses, identification numbers, and document references.
Separate facts personally known to you from information received from others.
Mark attachments consistently and bring clear originals or acceptable copies.
Bring the original current government-issued ID with photograph and signature.
Arrange qualified credible witnesses in advance if you cannot present ordinary identification.
Leave the affidavit unsigned when a jurat requires signing in the notary’s presence.
Do not leave material blanks.

During notarization

Appear personally and meet the actual commissioned notary.
Read the entire affidavit and attachments.
Ask for corrections before signing.
Take the oath or affirmation administered by the notary.
Sign the affidavit and notarial register as directed.
Watch the notary complete and sign the certificate and affix the official seal.
Check the commission details and register references.

After notarization

Make a complete scan or photocopy, including attachments and the notarial page.
File it using the recipient’s authorized channel before the deadline.
Keep proof of submission and payment.
Preserve the source records supporting every material statement.
Do not add text, replace pages, remove attachments, or alter dates after notarization.
If a correction is needed, execute a properly corrected or supplemental document instead of tampering with the original.

Evidence to preserve

Keep records that can verify both the affidavit’s contents and its proper execution:

The final notarized original and a complete digital copy
Earlier drafts showing legitimate corrections
The recipient’s official form, checklist, notice, or instructions
IDs presented to the notary
Receipts and appointment records
Emails, messages, photographs, videos, and contemporaneous notes relevant to the facts
Contracts, certificates, reports, account statements, registry records, and official correspondence
Proof of mailing, electronic filing, personal delivery, or receipt
Apostille or consular documentation when executed abroad
Information identifying the notary and the notarial register entry

Preserve original electronic files and metadata where authenticity or timing may later be disputed. Do not edit screenshots or recreate missing communications.

Common mistakes

Using an acknowledgment instead of a jurat
Signing outside the notary’s presence
Allowing someone else to appear for the affiant
Relying only on a cedula
Using an expired or mismatched ID
Swearing to facts outside personal knowledge without identifying the source
Copying a template that does not match the legal purpose
Leaving names, dates, amounts, attachments, or the jurat blank
Accepting notarization performed only by office staff
Altering the affidavit after notarization
Assuming notarization has no expiry issue without checking the recipient’s freshness requirement
Treating notarization as proof of title, authority, or the truth of all allegations
Missing a filing deadline while waiting for notarization
Assuming a foreign notarization is automatically usable in the Philippines
Paying a fixer for appearance-free or backdated notarization

Does an affidavit expire?

Philippine notarial rules do not impose one universal expiry period for every affidavit. Its usefulness depends on:

Whether its statements remain true
The law governing its purpose
The receiving institution’s rules
A stated validity period on the form
Whether later events made it inaccurate or incomplete

An agency or private institution may require a recently executed affidavit even when an older one has not become legally void. Never change the old date or request backdating. Execute a new or updated affidavit if current facts must be sworn to.

When legal help is urgent

Consult a Philippine lawyer promptly if:

You received a subpoena, summons, court order, prosecutor’s notice, or administrative charge.
A filing or response deadline is approaching.
Someone asks you to sign facts you do not know or believe.
The affidavit may admit a crime, debt, fraud, professional violation, tax issue, immigration breach, or breach of contract.
The matter involves land, inheritance, corporate control, custody, large sums, or competing claimants.
Your signature or notarization appears forged, fabricated, or entered in a register without your appearance.
You signed under threat, deception, or serious misunderstanding.
Pages or attachments were changed after you signed.
A notary refuses to provide identifying or register information needed for a legitimate dispute.
A foreign affidavit has been rejected for lack of Apostille, authentication, translation, or proper form.

For suspected notarial misconduct, preserve the document and supporting evidence. Depending on the facts, remedies may involve the Executive Judge or Office of the Clerk of Court responsible for the notarial commission, the Integrated Bar of the Philippines, law-enforcement authorities, or the court or agency handling the underlying matter. Obtain advice before alleging forgery or perjury.

Frequently asked questions

Can I notarize an affidavit without appearing personally?

Not through ordinary paper notarization. Personal appearance is a core requirement. A properly authorized electronic notarization is possible only through a commissioned Electronic Notary Public and the official process; an informal video call or emailed scan is insufficient.

Can I use a photocopy or phone image of my ID?

Expect to present the original current government-issued identification document. A notary may keep or create the records required by the rules. A photocopy or phone image alone may not allow reliable identity verification.

Is a barangay ID acceptable?

It may qualify if it is current, officially issued, and bears the required photograph and signature, but the notary must determine whether it satisfies the rules and reliably establishes identity. Bring a stronger primary government ID if available.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity for notarization under the present rule.

May I use an e-signature on an ordinary scanned affidavit?

Not as a substitute for compliance with the Rules on Electronic Notarization. Whether an electronic signature is valid for other purposes is a separate question under electronic-commerce law, but a valid electronic affidavit requires the prescribed oath and electronic notarial process.

Must every page be signed?

The notarial rules and recipient’s form determine the exact requirement. Signing or initialing every page is often requested to reduce page-substitution disputes, but it does not replace the signature and oath required for the affidavit. Follow the official form and the notary’s lawful instructions.

Can a notary prepare the affidavit?

A lawyer may draft or review an affidavit as a legal service. Drafting and notarization are distinct services and may involve separate fees. The affiant remains responsible for reading the document and swearing only to accurate facts.

Can the same notary notarize an affidavit for a relative?

Not where the notary is disqualified because the affiant is the notary’s spouse, common-law partner, ancestor, descendant, or relative within the prohibited fourth civil degree by affinity or consanguinity. Use an independent notary.

Does notarization make a false affidavit legally valid?

No. Notarization does not legalize a falsehood. A knowingly false material statement may lead to perjury or other liability when the legal elements are established.

Is a notarized affidavit automatically admissible in court?

No. Authentication is only one evidentiary issue. Relevance, hearsay, personal knowledge, procedural compliance, timely filing, opportunity for cross-examination, and other rules may affect admissibility and weight.
