Quick answer

An affidavit is ordinarily completed by signing it under oath or affirmation before a notary public or another officer legally authorized to administer oaths. For a paper affidavit, the affiant must personally appear, prove identity, sign in the notary’s presence, and take the oath or affirmation. The notary then completes a jurat stating the actual place and date of the oath.

Do not sign a paper affidavit in advance unless the notary instructs you to sign again in the notary’s presence. Do not use a notary who offers to process it without seeing you. A cedula or community tax certificate alone is not competent proof of identity.

There is no single format, filing deadline, validity period, or government fee for every affidavit. The law, court, agency, bank, school, employer, or transaction requiring the affidavit may prescribe its own form, supporting documents, recency rule, witnesses, filing channel, and deadline. Obtain those requirements before drafting or notarizing anything.

What makes a document an affidavit?

An affidavit is a written statement of facts voluntarily made under oath or affirmation before a person authorized to administer it. A proper affidavit normally contains:

The correct title, and the case caption and docket number if it relates to an existing proceeding.
A venue showing where the oath is actually administered.
The affiant’s complete legal name and the identifying details required for the particular purpose.
Clear, numbered statements of fact.
An explanation of how the affiant personally knows each material fact.
Identification of any attached supporting documents.
The affiant’s signature.
A jurat completed by the notary or other authorized officer.

A signed narrative without an oath and jurat may still be a written statement, but it is generally not a completed affidavit when the receiving authority requires a sworn or notarized affidavit.

Use only relevant personal details. Age, citizenship, civil status, occupation, and full address are common in legal forms, but they should not be included merely by habit if the receiving authority does not need them.

Jurat or acknowledgment: which one is correct?

These are different notarial acts and should not be interchanged.

Notarial act	What the signer does	Usual use
Jurat	Personally appears, is properly identified, signs in the notary’s presence, and swears or affirms that the document’s contents are true	Affidavits, sworn statements, verifications and other documents requiring an oath
Acknowledgment	Personally appears with a complete document, is properly identified, and declares that the document and signature are the signer’s free and voluntary act; representative authority must also be declared when applicable	Contracts, deeds, powers of attorney and other instruments executed as voluntary acts
Signature witnessing	Personally appears, is identified, and signs in the notary’s presence	Documents requiring the notary to witness the signature but not necessarily an oath

For a traditional paper jurat, all four requirements matter: personal appearance, proper identification, signing in the notary’s presence, and the oath or affirmation. An acknowledgment certificate attached to an affidavit does not perform the same function as a jurat.

Who may notarize or administer the oath?

A lawyer is not automatically a notary public. For traditional paper notarization, the lawyer must hold a current commission issued by the Executive Judge of the Regional Trial Court for the relevant city or province. The notary ordinarily acts at the regular place of work or business and within the territorial jurisdiction of that commission.

Other public officers have statutory authority to administer oaths, including members of the judiciary, clerks of court, certain national and local officials, registrars of deeds, constitutional officers, and notaries public. Their authority or duty may be limited by the nature of the matter and their official functions. A punong barangay’s additional authority under Republic Act No. 10755 specifically concerns administering the oath of office of government officials; it does not make every punong barangay a general notary public. See the official text of Republic Act No. 10755.

If a form says “notarized affidavit,” use a duly commissioned notary unless the receiving authority expressly confirms that an oath before another authorized officer is acceptable.

What to bring to a paper notarization

Bring:

The complete affidavit, with all pages and attachments present and in their final order.
At least one current identification document issued by an official agency and bearing both your photograph and signature.
Any additional ID requested by the notary or receiving authority.
Original supporting documents when the notary must examine them.
Any required disinterested witnesses, particularly if identity must be established through credible witnesses or the affiant will sign by a mark.
The filing authority’s prescribed form or written checklist.
Payment for the disclosed notarial and drafting services, if any.

Names in the affidavit should match the ID. Explain legitimate differences—such as a married surname, typographical error, or name appearing differently in civil-registry records—before signing. Supporting records or a separate affidavit may be needed.

Acceptable proof of identity

Under the amended identity rule, competent evidence ordinarily means at least one current official identification document bearing the individual’s photograph and signature. The list in the rule is illustrative rather than exclusive and includes documents such as passports, driver’s licenses, PRC IDs, certain government service IDs, senior-citizen IDs, seaman’s books, and government-office IDs.

A cedula or community tax certificate alone is insufficient, principally because it does not bear the photograph and signature required by the rule. The Supreme Court applied this requirement in Heir of Unite v. Guzman.

If the signer has no qualifying ID, the rules provide a credible-witness route:

One credible witness who is not involved in the transaction, is personally known to the notary, and personally knows the signer; or
Two credible witnesses who are not involved in the transaction, each personally knows the signer, and each presents documentary identification.

Do not assume that any companion can act as a credible witness. Arrange this with the notary before the appointment.

What should happen during notarization?

For a paper affidavit, the proper sequence is:

The notary examines the complete document. Blank material portions, missing pages, inconsistent attachments, or an apparently unlawful purpose can justify refusal.
The notary verifies identity. The ID or credible-witness details should be recorded.
The notary evaluates willingness and basic understanding. The notary must refuse if there is reason to believe the signer does not understand the consequences or is not acting freely.
The affiant signs in the notary’s presence.
The notary administers the oath or affirmation. The affiant must avow the truth of the affidavit under penalty of law.
The notary completes the jurat and register entry. The affiant signs or places the proper mark in the notarial register.
The notary signs and affixes the official seal.

The jurat should reflect the real date and place of appearance—not the date the affidavit was drafted or the location of the event being described. Backdating and falsely certifying personal appearance are not acceptable.

Before leaving, check that the notarial certificate is complete. A traditional certificate should show the type of notarial act, actual place and date, the notary’s signature and seal, commission details, office address and required professional details, and the document, page, book and series numbers.

Drafting facts that can withstand scrutiny

A notarized affidavit can affect a court case, government investigation, property transaction, employment matter, insurance claim, immigration application, or another person’s rights. Write it as evidence, not as an argument or social-media post.

Use these practices:

State events chronologically.
Give exact dates, times, locations and amounts when genuinely known.
Identify people by complete name and role.
Separate what you personally saw, heard or did from what another person told you.
If a date or amount is approximate, say so.
Quote only words you accurately remember or can support with a record.
Avoid legal labels such as “fraud,” “theft,” “harassment” or “ownership” when the affidavit can instead state the underlying facts.
Explain corrections openly. Never erase or conceal a material inconsistency.
Refer to each attachment in the body and label it consistently.
Do not include facts merely because someone instructed you to say them.

Read the entire affidavit—including attachments and the oath language—before signing. Ask for translation or explanation if you do not fully understand the language used.

Knowingly making a materially false statement under oath may constitute perjury under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594. The amended law imposes criminal penalties and provides additional consequences in specified circumstances. See the official text of Republic Act No. 11594.

What notarization does—and does not—prove

Proper notarization gives a private document the evidentiary character attached to a public document as to its due execution and authenticity. It creates important presumptions about the signer’s appearance and execution of the document.

It does not automatically establish that:

Every factual assertion is true.
The affiant owns the property mentioned.
The transaction is lawful, valid or enforceable.
The signer had authority that the underlying records do not support.
A filing deadline was met.
The receiving agency must accept the document.
Fraud, forgery, coercion or incapacity can no longer be proved.

The Supreme Court has explained that a notarized document is generally evidence of the fact and date of its execution, not conclusive proof of every statement it contains. Defective notarization can strip the document of its public character and reduce it to a private document whose due execution and authenticity must be proved. See Dadis v. Spouses De Guzman and

Quick answer

An affidavit is ordinarily completed by signing it under oath or affirmation before a notary public or another officer legally authorized to administer oaths. For a paper affidavit, the affiant must personally appear, present acceptable proof of identity, sign in the notary’s presence, and take the oath. The notary then completes a jurat stating the actual place and date of the oath.

A lawyer is not automatically a notary public. For traditional paper notarization, the lawyer must hold a valid notarial commission for the relevant territorial jurisdiction. Do not use a notary who offers to notarize an affidavit without seeing the affiant, asks someone else to bring the signed document, backdates the jurat, or relies only on a cedula.

Electronic and remote notarization are legally recognized for qualifying electronic documents, but only through a commissioned Electronic Notary Public and the system required by the Supreme Court. An ordinary video call, emailed signature, or scanned stamp is not enough.

What makes a document an affidavit?

An affidavit is a written statement of facts voluntarily declared under oath or affirmation. It normally contains:

The correct title and, if applicable, the court, agency, case number, or transaction to which it relates.
The affiant’s full legal name and sufficient identifying information.
Clear, preferably numbered statements of fact.
An explanation of how the affiant personally knows each material fact.
References to supporting documents, photographs, messages, records, or other attachments.
The affiant’s signature.
A properly completed jurat.

There is no single form that works for every purpose. Affidavits of loss, support, discrepancy, adverse claim, desistance, correction, heirship, consent, and complaint may have different statutory or agency requirements. Courts, prosecutors, banks, schools, registries, immigration authorities, and government agencies may also prescribe their own forms, attachments, filing methods, and deadlines.

Obtain the receiving office’s current form or checklist before drafting. A technically notarized affidavit can still be rejected if it lacks information or evidence required for the particular proceeding.

Jurat versus acknowledgment

An affidavit normally requires a jurat, not a simple acknowledgment.

Notarial act	What the signer must do	Common use
Jurat	Personally appear, be properly identified, sign in the notary’s presence, and swear or affirm that the contents are true	Affidavits, sworn statements, verifications
Acknowledgment	Personally appear with a complete document, be properly identified, and acknowledge that the signature and execution are the signer’s free and voluntary act; representative authority must also be acknowledged when applicable	Contracts, deeds, powers of attorney and similar instruments
Signature witnessing	Sign the document in the notary’s presence after identification	Documents requiring witnessed signatures but not necessarily an oath

For a jurat, signing beforehand is not the proper procedure. Bring the completed but unsigned affidavit and sign it when instructed. If it was signed earlier, tell the notary; the notary may require a fresh signature or a properly corrected document.

The jurat’s place and date must reflect where and when the affiant actually appeared and took the oath. It must never be backdated.

Requirements for traditional paper notarization

The 2004 Rules on Notarial Practice, as amended, generally require the following.

Personal appearance

The affiant must be physically present before the notary at the time of notarization. Sending the affidavit through a relative, liaison, secretary, or courier does not satisfy this requirement.

The notary should also assess whether the affiant:

Understands the document and its consequences.
Is acting voluntarily.
Has the apparent capacity to execute it.
Is not being coerced or deceived.

The notary must refuse the act when the transaction appears unlawful or immoral, the signer does not appear to understand its consequences, or the signer does not appear to be acting freely.

A complete document

The affidavit should be complete when presented. Avoid:

Blank factual paragraphs.
Missing pages.
Unidentified attachments.
Empty spaces that could later be filled in.
Unexplained erasures, white-out, or alterations.
A detached signature or jurat page that could be attached to another document.

If a correction is necessary, make it before notarization and follow the notary’s instructions. Never insert, delete, replace, or rearrange pages after the notarial act.

Competent evidence of identity

Unless the affiant is genuinely personally known to the notary through prior firsthand knowledge, the usual requirement is at least one current identification document issued by an official agency and bearing both the affiant’s photograph and signature.

Examples recognized by the rules include passports, driver’s licenses, PRC IDs, government employee IDs, SSS or GSIS cards, senior-citizen cards, seaman’s books, and other qualifying government-issued documents. Because formats and security features change, confirm in advance whether the notary and receiving office will accept the particular ID.

A community tax certificate or cedula alone is not competent evidence of identity because it does not carry the required photograph and signature. The Supreme Court applied this rule in Heir of Unite v. Guzman.

When documentary identification is unavailable, the rules provide a limited credible-witness method:

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 to the notary.

A notary may reasonably request additional identification where names differ, an ID is damaged, identity is doubtful, or the transaction presents a heightened risk.

A valid and properly commissioned notary

Check that the notarial certificate identifies the notary and ordinarily contains the necessary commission and professional details, including the commission’s territorial coverage and validity, Roll of Attorneys number, PTR and IBP information, office address, and the document, page, book, and series numbers in the notarial register.

Traditional notarization is generally performed at the notary’s regular place of work or business within the territory covered by the commission. Limited exceptions permit notarization within that jurisdiction at specified places, such as:

A public office or similar venue for an oath of office.
A public function area used for document signing.
A hospital or medical institution where a signer is confined.
A place where a signer is detained.

A traditional notary commissioned in one city or province cannot simply notarize paper documents anywhere in the Philippines.

The notary is disqualified if the notary is a party to the document, will receive a prohibited direct or indirect benefit from it, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

The notarial register

The affiant ordinarily signs or places the appropriate mark in the notarial register. The entry creates a traceable record of the act. A document that was stamped and signed but never properly entered or reported may lose the evidentiary treatment given to a duly notarized public document.

If the transaction is important, record the notary’s full name, office, commission details, and the document, page, book, and series numbers. Keep the receipt and a complete copy of the document.

What to bring

Unless the relevant office requires more, prepare:

The complete but unsigned affidavit.
Every page and attachment referred to in it.
The original current government-issued ID bearing your photograph and signature.
A second ID if available or requested.
Original supporting records for comparison.
Required witnesses, if using the credible-witness procedure or signing by a mark.
The receiving office’s form, instructions, or written checklist.
The applicable fee.

Names in the affidavit, ID, and attachments should be consistent. If they are not, explain the discrepancy accurately and bring supporting records such as a birth, marriage, or correction document.

Practical drafting checklist

State facts, not conclusions you cannot support

Describe what happened, when and where it happened, who was present, and how you know. Distinguish:

What you personally saw, heard, received, or did.
What a record shows.
What another person told you.
What you merely suspect or infer.

Do not present hearsay or assumptions as personal knowledge. If information came from another source, identify that source when legally appropriate.

Use precise dates and descriptions

Avoid vague statements such as “recently,” “many times,” or “a large amount” when records can provide exact dates, frequency, or amounts. If the exact detail is honestly unknown, say so rather than guessing.

Identify attachments clearly

Refer to each attachment in the body and mark it consistently, for example as Annex “A” or Exhibit “1.” Confirm that names, dates, page counts, and descriptions match the affidavit.

Do not attach an edited screenshot when the original message, email, file, or export is available. Preserve the original electronic record and its metadata.

Read every statement before swearing

An affiant adopts the complete contents of the affidavit. Do not sign merely because a police officer, employer, relative, claims handler, investigator, or opposing party prepared it. Correct statements that are inaccurate, incomplete, exaggerated, or outside your knowledge.

Knowingly making a material false statement under oath may constitute perjury under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594. Other conduct may also expose a person to liability for falsification, fraud, obstruction, or offenses specific to the proceeding.

Does notarization prove that every statement is true?

No. A notary verifies the appearance and identity of the signer and performs the required acknowledgment, oath, jurat, or other notarial act. The notary does not automatically investigate and certify the objective truth of every factual allegation.

Proper notarization generally gives a document public-document status and a presumption concerning its authenticity and due execution. It does not:

Make a false statement true.
Cure an illegal or void transaction.
Establish ownership by itself.
Replace evidence required by a court or agency.
Prevent the document from being challenged.
Guarantee that the receiving office will accept it.

The Supreme Court has explained that defective notarization strips a document of its public character and reduces it to a private document whose execution and authenticity must be proved. See Dadis v. Spouses De Guzman and Requina v. Spouses Larrazabal.

Electronic and remote notarization

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

In-Person Electronic Notarization (IEN): The signer physically appears before an Electronic Notary Public, but the document and notarial process are electronic.
Remote Electronic Notarization (REN): The signer appears through synchronous videoconferencing using the required electronic-notarization system.
Hybrid electronic notarization: Participants may appear through the modes allowed by the rules.

Electronic notarization is not merely scanning a traditionally signed affidavit. It requires:

A duly commissioned Electronic Notary Public.
A qualifying electronic document, generally in PDF or PDF/A format.
Use of an accredited Electronic Notarization Facility.
Identity verification through the facility.
The required electronic signatures, certificate, seal, records, and audit trail.
Live interaction for REN; prerecorded signing videos are prohibited.
Compliance with location and geolocation requirements.

The legal framework is in force, but actual service availability depends on commissioned electronic notaries and accredited facilities. Verify providers through the Supreme Court’s eNotary Services portal rather than relying solely on a provider’s advertisement.

The rules do not cover notarial wills, deposition taking, or paper documents bearing wet signatures or marks. These remain subject to their governing paper-document rules. The earlier pandemic-era interim system for remotely notarizing paper documents has been repealed; an ordinary Zoom call is therefore not a substitute.

For REN, participants are generally required to be physically located in the Philippines. A limited extraterritorial procedure may be available when a principal abroad is physically within a Philippine embassy, consular office, or office of a Philippine honorary consul and all prescribed verification requirements are met.

Paper notarization and the 2025 digital-reporting amendments

The 2025 amendments to the 2004 Notarial Rules added electronic recordkeeping and reporting duties for traditional notaries. Among other requirements, notaries must transmit the prescribed PDF copies of monthly notarial entries and duplicate originals of covered acknowledged instruments to the clerk of court within the first ten days of the following month.

For covered documents, the amended rules also provide for electronic transmittal to signatories, without an additional digitization, transmission, or processing fee, within the period stated in the rules. A signatory may waive that transmittal, but the waiver affects objections concerning the completeness of the reproduction.

These are principally duties of the notary. They do not replace the affiant’s separate filing deadline with the court, prosecutor, agency, or other recipient, and a scanned copy transmitted under these amendments is not automatically an electronically notarized document.

Affidavits signed abroad

A person abroad commonly has two routes:

Execute the affidavit before a Philippine embassy or consulate offering notarial services; or
Execute it before a competent local notary or authority and obtain the authentication required for Philippine use.

If the country is a party to the Apostille Convention, a properly issued apostille will generally replace further Philippine embassy legalization. For a non-Apostille country, consular authentication or legalization may still be required. The exact chain depends on the country, the type of document, and the Philippine recipient.

Confirm the procedure with both the relevant Philippine foreign-service post and the receiving office before signing. The DFA explains that foreign documents are not apostilled by the Philippine DFA merely because they will be used here; apostillization is ordinarily performed by the competent authority of the country where the document originated. See the DFA Apostille FAQs and documentary requirements.

Consular appointment systems, identification requirements, fees, and processing periods vary by post.

If the affiant cannot sign conventionally

A person may sign by thumbmark or another mark under the safeguards in the notarial rules. The mark must be made in the presence of the notary and two disinterested, unaffected witnesses, who must also sign, and the prescribed notation and notarial act must be completed.

If the person is physically unable even to make a mark, the notary may sign on the person’s behalf only when:

The person directs the notary to do so.
Two disinterested and unaffected witnesses are present.
The witnesses sign.
The required explanatory notation is placed on the document.
The notary completes the appropriate acknowledgment or jurat.

Arrange this with the notary in advance. Capacity, communication, voluntariness, medical condition, venue, and witness arrangements may require special preparation.

Fees and receipts

There is no reliable universal price for every affidavit or transaction. Charges may differ because drafting, consultation, copying, travel, and notarization are distinct services.

A notary who charges for notarial services must post a complete schedule of chargeable fees, issue a BIR-registered receipt, and record the fee in the journal required by the rules. Ask for the price before work begins and request an itemized explanation where drafting or professional advice is charged separately.

Under the 2025 paper-notarization amendments, the required electronic transmittal of covered duplicate originals to signatories cannot carry an additional digitization, transmission, or processing fee.

Deadlines and validity

There is no single nationwide deadline for executing or filing every affidavit. The controlling deadline comes from the law, court rule, agency issuance, order, contract, or receiving office governing its purpose. Notarizing an affidavit does not extend a filing deadline.

A properly notarized affidavit also has no universal automatic expiration date. However:

An agency may require an affidavit executed within a stated recent period.
The facts certified may become outdated.
An ID, authority, commission, or supporting document may expire.
A transaction may have its own prescription, registration, or filing deadline.
A court may reject a late affidavit even though it was notarized on time.

Always ask the recipient for the exact cut-off date, acceptable filing channel, number of copies, and whether receipt—not mailing or dispatch—constitutes timely filing.

Evidence to preserve

Keep:

The exact final affidavit, including its jurat and every attachment.
The notary’s name, office, commission and register details.
The receipt and any authorized electronic copy.
Original source documents and unedited electronic files.
Messages, emails, photographs, videos, metadata, CCTV requests, travel records, medical records, contracts, and payment records relevant to the statements.
Proof of submission, service, email delivery, upload confirmation, or receiving stamp.
Earlier drafts when they help show how an error was corrected, but clearly label them as drafts.

Do not circulate IDs or sensitive supporting documents more widely than necessary.

Common mistakes

Signing a jurat affidavit before meeting the notary.
Allowing a liaison to obtain notarization in the affiant’s absence.
Using only a cedula as identification.
Leaving blanks or attaching pages after notarization.
Using an acknowledgment when a jurat is required.
Giving approximate facts when exact records are available.
Swearing to matters based only on rumor.
Using a notary outside the commission’s territorial jurisdiction.
Assuming every lawyer is a commissioned notary.
Treating an ordinary video call as valid remote notarization.
Assuming notarization proves ownership or the truth of every allegation.
Missing the recipient’s filing deadline while arranging notarization.
Failing to keep the complete notarized copy and proof of filing.

When legal help is urgent

Consult a Philippine lawyer promptly before signing—or immediately after discovering a problem—when the affidavit:

May expose you or another person to criminal liability.
Concerns land, inheritance, corporate ownership, a large financial transaction, or an irrevocable waiver.
Was prepared by an opposing party or investigator.
Contains an admission, confession, quitclaim, desistance, settlement, or waiver of rights.
Will be used in a pending court, prosecution, immigration, tax, labor, or administrative case.
Must be filed before a deadline that is close or disputed.
Was allegedly signed or notarized without your presence.
Contains a forged signature, false jurat, altered page, or suspicious notarial details.
Was signed while the affiant was ill, detained, impaired, threatened, or unable to understand it.

For a suspected forged or irregularly notarized document, preserve the original and complete copies, do not write on them, and ask the relevant RTC Office of the Clerk of Court to verify the notary’s commission and available notarial entry or report. Preserve independent evidence such as travel, employment, medical, location, communication, and signature records.

Frequently asked questions

Must a lawyer prepare an affidavit?

Not always. A person may draft a simple affidavit, and some agencies provide official forms. Legal review is advisable when rights, liability, contested facts, property, money, or court proceedings are involved. Notarization alone is not legal review.

Is one government ID enough?

The rules allow at least one current official identification document bearing both photograph and signature. A notary or receiving institution may reasonably require another ID because of discrepancies, damage, fraud risk, or its own lawful requirements.

Can I use a cedula or barangay clearance?

A cedula alone is not competent evidence of identity. A barangay-issued document is useful only if it satisfies the governing identification standard and the notary accepts it. Bring a current government-issued photo-and-signature ID whenever possible.

Can an affidavit be sworn before someone other than a notary?

Yes, where the law authorizes the officer to administer the relevant oath and the receiving body accepts it. The Administrative Code identifies several officials with authority to administer oaths, but many public officers exercise that power only in official matters or under a specific law. A punong barangay’s special authority under Republic Act No. 10755 concerns oaths of office; it is not a general power to notarize private documents.

Can I notarize a document after the signer has left?

Not by pretending the signer appeared. A paper affidavit requiring a jurat must be signed and sworn to in the signer’s personal presence. Electronic notarization must follow the separate Supreme Court framework.

Does a notarized affidavit expire?

There is no universal expiration period, but the recipient may require a recently executed affidavit or current supporting documents.

Is a photocopy of a notarized affidavit as good as the original?

That depends on its purpose. A receiving office may demand the original, a certified copy, or an authorized electronic version. Confirm before surrendering the only original.

Can several affiants sign at different times?

Potentially, but each affiant must comply with the required appearance, identification, signing, and oath. Separate jurats or separate notarizations may be necessary. Do not use one jurat that falsely states everyone appeared together.

Does notarization make an invalid agreement valid?

No. Notarization cannot supply missing consent, authority, capacity, lawful purpose, mandatory statutory contents, or other essential legal requirements.
