Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. For an ordinary paper affidavit in the Philippines, the affiant must personally appear before a duly commissioned notary public or another officer legally authorized to administer oaths, prove identity, sign in that officer’s presence, and swear or affirm that the contents are true.

Do not sign the affidavit in advance unless the receiving office expressly requires a different notarial act. Affidavits ordinarily require a jurat, not a mere acknowledgment. A valid jurat requires personal appearance, proper identification, signing before the notary, and an oath or affirmation. Sending a signed document or scanned ID to a notary is not enough.

Notarization does not make a false statement true, cure an incomplete document, or guarantee that an agency or court will accept it. The affidavit must also satisfy the particular law, rule, form, supporting-document requirement, and filing deadline for its intended use.

What an affidavit should contain

There is no single form for every affidavit. Requirements depend on its purpose, but a sound affidavit normally contains:

A descriptive title, such as “Affidavit of Loss,” “Affidavit of Discrepancy,” or “Complaint-Affidavit.”
The affiant’s complete name, citizenship when relevant, age or confirmation of legal age, civil status when material, and current address.
A statement that the affiant is competent to testify about the facts stated.
Clear, numbered paragraphs describing facts in chronological order.
Specific dates, places, names, transactions, and document details when known.
An explanation of how the affiant personally knows each material fact.
Identification of supporting documents, photographs, messages, receipts, or records attached as annexes.
The exact purpose for which the affidavit is being executed.
The affiant’s signature or permitted mark.
A complete jurat to be filled out and signed by the administering officer.

Use facts, not exaggeration or legal conclusions. If information came from another person or record, say so and identify the source instead of presenting it as something personally witnessed. An affidavit based mainly on hearsay may have little evidentiary value unless a rule permits it.

For an affidavit of loss, for example, state what was lost, identifying numbers if known, when and where it was last seen, the circumstances of the loss, the search made, and the purpose of requesting replacement or cancellation. Do not use a generic affidavit if the issuing agency has its own prescribed form.

Jurat versus acknowledgment

These notarial acts are not interchangeable.

Jurat

A jurat is normally required for an affidavit. Under the 2004 Rules on Notarial Practice, the affiant must:

Personally appear before the notary.
Present the affidavit.
Be personally known to the notary or identified through competent evidence of identity.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation regarding its contents.

The usual wording is “subscribed and sworn to before me,” although the wording and required details may vary with the prescribed form.

Acknowledgment

In an acknowledgment, the signer appears before the notary and represents that the signature is genuine and that the document was executed voluntarily. The document may have been signed earlier.

An acknowledgment is commonly used for deeds, contracts, and other instruments. It is generally not a substitute for the oath required in an affidavit. Using the wrong notarial certificate can cause rejection or affect the document’s evidentiary value.

Personal appearance is mandatory

For conventional paper notarization, the affiant must be in the notary’s physical presence when the jurat is completed. A friend, relative, liaison officer, or employee cannot appear in the affiant’s place. A representative cannot swear that another person’s personal account is true.

Never agree to:

Leave an unsigned affidavit and ID at a notarial office for later processing.
Send a pre-signed affidavit for someone to have notarized.
Sign an affidavit in a blank or incomplete form.
Use a notarial certificate bearing an earlier or later date than the actual appearance.
Have a notary affix a seal without administering an oath.
Use another person’s ID or ask someone else to sign for the affiant.

The Supreme Court repeatedly treats notarization without the signer’s personal appearance as a serious breach. Defective notarization may strip a document of its public character and reduce it to a private document whose execution and authenticity must be separately proved. In some proceedings, a defective oath can also lead to dismissal or rejection. See, for example, Sanchez v. Inton and De Lima v. Guerrero.

Identification requirements

If the notary does not personally know the affiant, the general rule is to present at least one current identification document issued by an official agency bearing the individual’s photograph and signature. A current passport, driver’s license, or PRC ID will ordinarily meet the text of the rule, subject to the notary’s verification.

Bring the original ID, not merely a screenshot or photocopy. Ensure that:

The name reasonably matches the affidavit.
The photograph is recognizable.
The ID has not expired.
The signature is visible.
Any name discrepancy is explained and supported by appropriate records.

The 2008 amendment on competent evidence of identity contains a non-exclusive list of qualifying government-issued documents.

A community tax certificate or cedula is not, by itself, competent evidence of identity under the Notarial Rules. It may be required separately for another legal or administrative purpose, but it does not replace the required identification for notarization. The Supreme Court has expressly rejected reliance on a cedula alone, including in Gonzales v. Ramos.

The Philippine Identification System Act states that the PhilID or authenticated PSN must be accepted as sufficient proof of identity, subject to authentication. Because some National ID formats do not display a handwritten signature while the Notarial Rules refer to an official ID bearing both photograph and signature, bring another current signed government ID when available and ask the notary in advance how authentication will be handled. See Republic Act No. 11055.

When documentary identification is genuinely unavailable, the Notarial Rules provide a credible-witness method with strict conditions. It is not enough for an interested relative, transaction participant, or casual companion simply to vouch for the affiant. Arrange this with the notary beforehand.

Who may administer the oath

A commissioned notary public may perform notarial acts only within the territorial jurisdiction covered by the commission. Confirm that the commission is current and that the place stated in the jurat is where the notarization actually occurred.

Philippine law also gives general authority to administer oaths to specified public officers. The current list includes members of the judiciary, clerks of court, provincial governors, city and municipal mayors, certain national and regional officials, constitutional officers, and notaries public. Other officers may have limited authority for matters connected with their official duties. See Republic Act No. 10755.

That authority does not mean every listed officer offers notarial services to the public or may act in every private transaction. If a court, prosecutor, bank, school, insurer, or government agency prescribes who must administer the oath, follow that specific requirement.

What to bring to the notary

Unless the receiving office requires something different, prepare:

The complete but unsigned affidavit.
All pages and annexes referred to in the affidavit.
The original current government-issued ID or IDs.
Supporting records for any difference in name, civil status, address, or signature.
Enough unsigned originals if several original notarized copies are required.
The receiving office’s prescribed form, checklist, or written instructions.
Payment for the allowed notarial fee.

Read every page before signing. Check names, dates, document numbers, amounts, property descriptions, and annex labels. Tell the notary if you do not understand the language or legal effect of the document. A notary must refuse when there is reason to doubt that the signer understands the document, is acting freely, or is participating in an unlawful or immoral transaction.

A notary is also disqualified when the notary is a party to the document, will receive an improper interest from the transaction, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative within the fourth civil degree. The applicable disqualification rule is discussed in Vallejo.

Check the completed notarization

Before leaving, inspect the entire document. Confirm that:

You signed while physically before the notary, unless a valid electronic-notarization procedure was used.
The oath or affirmation was actually administered.
The venue and date are correct.
The notarial certificate is complete.
Blank spaces in the affidavit and jurat have been completed or properly cancelled.
The notary’s signature and official seal are present and legible.
The notary’s commission details appear as required.
The document has a notarial-register entry, usually reflected by its document, page, book, and series details.
Every annex mentioned is attached and correctly identified.
You received the complete notarized original or copy required for filing.

Do not alter, erase, replace pages, or add material facts after notarization. If a substantive correction is needed, ask the notary or receiving office whether a corrected affidavit, supplemental affidavit, or entirely new notarization is required.

The Supreme Court’s 2025 amendments to the Notarial Rules introduced digital recordkeeping and transmission safeguards for covered documents. They did not remove the basic requirements of identity verification, voluntary execution, a complete notarial certificate, and proper appearance. A separate fee may not be charged for required digitization, transmission, storage, or related processing.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, authorize in-person electronic notarization and remote electronic notarization of electronic documents through a commissioned Electronic Notary Public and an accredited electronic-notarization facility.

This is a regulated process. An ordinary video call, emailed scan, pasted image of a signature, or electronic signature placed on a PDF does not automatically produce a valid electronic notarization. Identity, location, electronic signing, audiovisual appearance where applicable, the electronic notarial certificate, tamper-evident handling, and record retention must comply with the Rules.

Before relying on remote notarization:

Confirm that the notary is commissioned as an Electronic Notary Public.
Use the approved facility and procedure specified by the notary.
Ask the receiving office whether it accepts an electronically notarized affidavit.
Confirm whether the document must remain electronic or whether a certified paper output is required.
Preserve the completed electronic document, certificate, audit information supplied to you, and proof of submission.

The Supreme Court maintains an official eNotary Services page and FAQ. Do not assume that pandemic-era informal arrangements or remote paper-signing practices satisfy the current permanent rules.

Affidavits executed abroad

An affidavit signed abroad for use in the Philippines may be executed before an authorized Philippine consular officer where that service is available. Personal appearance, a valid passport or acceptable photo ID, an appointment, copies, and consular fees may be required. Requirements and processing times differ by foreign service post, so check the website of the Philippine embassy or consulate with jurisdiction over your location.

Another possible route is notarization before a competent notary in the foreign country, followed by an apostille from that country’s designated authority if both countries use the Apostille Convention. For a non-Apostille country, authentication or legalization may be required. The Philippine receiving court or agency may also require an English translation, proof of the foreign notary’s authority, or a particular form.

An apostille authenticates the origin of the public or notarized document; it does not certify that the affidavit’s factual statements are true. Verify the exact destination requirement before paying for notarization or authentication. The DFA’s official Apostille FAQ explains that private documents can be authenticated only after notarization.

Notarization does not prove everything stated

Proper notarization gives the notarial act and qualifying document significant evidentiary consequences, particularly regarding authenticity and due execution. Under Rule 132 of the Rules on Evidence, documents acknowledged before a notary public, except last wills and testaments, are public documents.

That does not make every statement conclusive. A notarized document may still be challenged for forgery, fraud, coercion, mistake, simulation, lack of authority, illegality, or false contents. The Supreme Court has stressed that notarization is not a guarantee of a document’s validity in Dizon v. Matti.

An affidavit may also be hearsay when offered to prove its contents without the affiant’s testimony, unless a rule or recognized exception allows its use. A court may require the affiant to testify and undergo cross-examination. Judicial affidavits are governed by a separate rule and ordinarily take the place of direct testimony only when the witness appears for examination. See the Judicial Affidavit Rule.

Filing deadlines and document age

There is no universal expiration period for all affidavits. The controlling deadline or freshness requirement comes from the transaction, court rule, law, agency checklist, subpoena, or order.

Examples include:

Judicial affidavits are generally filed and served no later than five days before the relevant pre-trial, preliminary conference, hearing, motion, or incident, subject to the Judicial Affidavit Rule and applicable exceptions.
Complaint-affidavits and counter-affidavits in criminal investigations follow the procedural rules and deadlines stated in the subpoena or prosecutor’s rules.
Banks, insurers, schools, licensing agencies, and issuing offices may require a recently executed affidavit even though no general law makes every older affidavit expire.
An affidavit concerning a continuing fact may become inaccurate when circumstances change.

Notarizing a document does not extend its filing deadline. Never backdate an affidavit to make it appear timely. If a deadline is approaching, obtain the receiving office’s written instructions and seek legal help promptly.

Evidence and records to preserve

Keep:

The complete notarized affidavit, including every page and annex.
A clear scan or photograph of the final document.
The draft and records used to verify dates and details.
Receipts, messages, emails, CCTV requests, incident reports, medical records, and other supporting evidence.
Proof of filing, including the receiving stamp, acknowledgment email, tracking record, or electronic receipt.
Any apostille, authentication certificate, certified translation, or consular receipt.
The notary’s name, office address, commission details, and notarial-register particulars.
Written communications about corrections, rejected filings, or suspected discrepancies.

Preserve original electronic files and metadata when the affidavit concerns messages, online transactions, recordings, or digital fraud. Avoid editing screenshots or forwarding files in ways that destroy useful metadata.

Common mistakes

Frequent problems include:

Signing before meeting the notary.
Using an acknowledgment when a jurat is required.
Relying only on a cedula as identification.
Presenting an expired, damaged, or mismatched ID.
Leaving dates, names, annex references, or the jurat blank.
Copying a generic online form that omits facts required by the receiving agency.
Stating conclusions or information from others as personal knowledge.
Attaching documents that contradict the affidavit.
Allowing pages to be substituted after signing.
Assuming notarization proves ownership, authority, citizenship, loss, or entitlement.
Believing that an affidavit has no consequences because it is “only for compliance.”
Waiting until the filing deadline to resolve ID, overseas authentication, or form problems.

False statements and coercion

Do not sign an affidavit containing facts you know are false, even if an employer, relative, police officer, fixer, or transaction partner says it is merely a formality. Ask that inaccurate language be removed or corrected.

Knowingly making a material false statement under oath in a case where the law requires an oath may constitute perjury. Republic Act No. 11594 increased the penalties under Article 183 of the Revised Penal Code. Depending on the facts, falsification, obstruction, fraud, contempt, administrative liability, damages, dismissal of a case, or loss of a claim may also be involved.

If you were forced to sign, your signature was forged, you never appeared before the named notary, or pages were changed after signing, preserve the original and all communications. Do not confront a suspected forger in a way that risks your safety or destroys evidence.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A filing, subpoena, counter-affidavit, appeal, or prescription deadline is near.
The affidavit concerns a criminal accusation, arrest, inquest, search, or possible self-incrimination.
You are being asked to admit liability, waive rights, transfer property, or identify another person as responsible.
The matter involves land, inheritance, corporate authority, immigration, custody, domestic violence, large financial exposure, or government benefits.
The signer is a minor, has impaired capacity, does not understand the language, or appears to be under pressure.
A notary allegedly acted without your appearance or permission.
The notarial register, commission, date, seal, signature, or venue appears false.
An overseas document must be used immediately in a Philippine court or agency.
The receiving office rejected the affidavit and the defect may affect substantive rights.

A notary verifies and certifies the notarial act; the notary is not necessarily acting as your lawyer. For a high-stakes affidavit, obtain independent legal advice before signing.

Frequently asked questions

Can I sign the affidavit before going to the notary?

For a jurat, no. You must sign in the notary’s presence and take the oath or affirmation. If you already signed, the notary may require a fresh copy or require you to sign again in an appropriate manner.

Is one valid ID enough?

The rule generally permits at least one current official-agency ID bearing the affiant’s photograph and signature. A notary may reasonably request additional proof when the ID cannot be authenticated, details do not match, or identity remains doubtful.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity for notarization, although another law or office may separately require it.

Does an affidavit expire?

Not automatically under one general rule. The receiving office may require a recently executed affidavit, and an affidavit can become inaccurate when facts change.

Can a scanned or electronically signed affidavit be notarized online?

Only through a procedure that complies with the Rules on Electronic Notarization and uses a commissioned Electronic Notary Public and accredited facility. Emailing a scan or joining an ordinary video call is not enough.

Does notarization prove that every statement is true?

No. It formally records the appearance, identification, oath or acknowledgment, and execution certified by the notary. The contents may still be disputed, and the affiant may have to testify.

Can I correct the affidavit after notarization?

Do not alter the notarized document yourself. A material correction normally requires a corrected or supplemental affidavit and a new notarial act, subject to the receiving office’s rules.

Where can I verify a questionable notarization?

Start with the notary and the Office of the Clerk of Court or Executive Judge of the Regional Trial Court that issued the commission. Bring the complete document and notarial-register details. If fraud, forgery, or professional misconduct is suspected, seek legal advice about the appropriate court, law-enforcement, or disciplinary process.
