Quick answer

An affidavit is a written statement made under oath or solemn affirmation. For an ordinary paper affidavit in the Philippines, the affiant must generally:

State facts truthfully and, as far as possible, from personal knowledge.
Personally appear before a commissioned notary public or another officer authorized by law to administer the oath.
Prove identity through personal knowledge of the notary or competent evidence of identity.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that its contents are true.
Have the notary complete the jurat, sign it, affix the official seal, and record the act in the notarial register.

Sending a signed document or ID to a notary through a messenger is not enough. A secretary or staff member cannot administer the oath or perform the notarial act for the lawyer. A cedula or community tax certificate alone is not competent proof of identity.

These are the general rules. Court affidavits, prosecutor’s affidavits, civil-registry documents, affidavits executed abroad, and electronic affidavits may have additional forms, evidence, deadlines, or filing requirements.

What notarization does—and does not do

Proper notarization helps establish the identity of the signer, the voluntariness of the act, and compliance with the required oath. It generally gives the document the character and evidentiary treatment of a public document.

Notarization does not:

Guarantee that every factual statement is true.
Prove ownership, authority, or the legal sufficiency of attached documents.
Cure fraud, forgery, incapacity, illegality, or a defective transaction.
Automatically make an affidavit admissible for every purpose.
Replace a required witness’s appearance and cross-examination in court.
Give an affidavit a universal expiration date or make it acceptable to every agency.

The Supreme Court has repeatedly emphasized that notarization is a public-interest safeguard, not a routine stamping service. An irregularly notarized document may lose the presumption of regularity and may be treated as a private document. See the 2004 Rules on Notarial Practice and the Court’s discussion in A.C. No. 12455.

Jurat versus acknowledgment

An affidavit ordinarily requires a jurat, usually beginning with “Subscribed and sworn to before me.”

For a jurat, the affiant must:

Personally appear before the notary.
Present the affidavit.
Be properly identified.
Sign in the notary’s presence.
Take an oath or affirmation concerning the document.

An acknowledgment is different. The signer appears and confirms that the signature was voluntarily placed on the completed document as the signer’s free act and deed. A document may have been signed before the acknowledgment, but personal appearance is still required.

Using an acknowledgment when a jurat is required can leave an affidavit improperly sworn. The label alone is not controlling; the actual notarial act and completed certificate must satisfy the applicable rule.

Requirements for an ordinary paper affidavit

The affidavit itself

There is no single universal form for every affidavit. Unless a law, court, or agency prescribes a form, a properly prepared affidavit will usually contain:

A title identifying its purpose.
The place of execution or venue.
The affiant’s complete name and necessary personal circumstances.
Clear, consecutively arranged statements of fact.
An explanation of how the affiant knows those facts.
Identification of relevant attachments.
A statement of the purpose for which the affidavit is executed.
The affiant’s signature over the printed name.
A complete jurat.

Include only necessary personal information. Notaries must keep notarial records, and copies may be transmitted to the clerk of court under the amended rules.

Personal knowledge and supporting documents

State what the affiant personally saw, heard, did, received, or otherwise directly knows. If a statement is based on records, identify those records and explain the affiant’s access to or responsibility for them.

Before notarization, gather supporting evidence such as:

Receipts, contracts, letters, and official notices.
Screenshots, emails, messages, call logs, and photographs.
Police, barangay, medical, employment, school, bank, or government records.
Proof of delivery or receipt.
Copies of IDs, certificates, or documents referred to in the affidavit.

Do not attach altered screenshots, edited documents, or incomplete excerpts that could mislead the reader. Keep the original electronic files and their metadata where possible.

Personal appearance

For a paper affidavit, the affiant must ordinarily be physically present before the notary at the time of notarization. The notary must personally verify identity, administer the oath, witness the signing, and complete the certificate.

An attorney-in-fact, relative, employee, or messenger cannot take the oath for the named affiant. A representative may execute a separate affidavit in the representative’s own name and capacity if legally authorized and if the statements truthfully reflect the representative’s knowledge, but that is not a substitute for another person’s oath.

For a joint affidavit, every named affiant must be properly identified, appear, sign, and take the oath.

Competent evidence of identity

If the affiant is not personally known to the notary, the general paper-notarization rule requires at least one current identification document issued by an official agency and bearing the person’s photograph and signature. Examples under the 2008 amendment to the Notarial Rules include passports, driver’s licences, PRC IDs, NBI or police clearances, government employment IDs, SSS or GSIS cards, senior-citizen cards, and other qualifying official identification.

Practical points:

Bring the original ID, not merely a photograph or photocopy.
The name and signature should be consistent with the affidavit.
If an ID is expired, damaged, unverifiable, or lacks a visible signature, bring another current qualifying ID and ask the notary in advance.
A cedula or community tax certificate alone is insufficient because it does not contain the required photograph and signature. The Supreme Court confirmed this in A.C. No. 12062.

If the affiant has no qualifying ID, the Rules provide a credible-witness alternative:

One credible witness who is personally known to the notary and personally knows the affiant; or
Two credible witnesses who personally know the affiant and present qualifying documentary identification.

A credible witness must not be a party to or otherwise privy to the document or transaction.

Oath or affirmation

The notary must actually administer an oath or solemn affirmation. Merely signing in a law office, paying a fee, and receiving a stamp is not enough.

The affiant should understand that the statements are being made under penalty of law. Knowingly making a material falsehood in a legally required affidavit or an affidavit made for a legal purpose may constitute perjury under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594. Honest error is not automatically perjury, but deliberate falsehoods can carry serious criminal consequences.

Complete notarial certificate

Before leaving, check that the jurat is complete and consistent with what happened. It should ordinarily show:

The proper venue.
The actual date of notarization.
The affiant’s personal appearance.
The oath or affirmation.
The affiant’s competent evidence of identity, when required.
The notary’s signature and official seal.
The notary’s commission details and territorial jurisdiction.
The document, page, book, and series references corresponding to the notarial register.

Blank identity fields, an incorrect venue, a future or backdated date, an expired commission, or missing commission details are warning signs. A notary is prohibited from signing or sealing a false or incomplete notarial certificate.

A practical step-by-step checklist

Before visiting the notary

Ask the receiving court, agency, school, employer, bank, insurer, or foreign authority for its current form and checklist.
Confirm the deadline, required number of copies, permitted language, attachments, witness requirements, and whether a recently executed affidavit is required.
Review every factual statement and remove guesses, exaggerations, and matters outside the affiant’s knowledge.
Fill all required blanks. Use “N/A” where the form permits it instead of leaving material spaces empty.
Prepare the original supporting documents and readable copies.
Bring a current qualifying government-issued ID.
Do not sign the paper affidavit in advance unless the authorized officer specifically instructs otherwise.

During notarization

Meet the actual commissioned notary, not only an assistant.
Present the complete affidavit and original ID.
Answer reasonable questions about identity, understanding, and voluntariness.
Take the oath or affirmation.
Sign in the notary’s presence.
Sign or place the required mark in the notarial register.
Obtain an official receipt for amounts paid.

The notary should refuse if the document is blank or materially incomplete, the affiant cannot be properly identified, the affiant does not understand or is not acting voluntarily, or the act appears unlawful.

After notarization

Check every page, attachment, signature, date, seal, and notarial entry reference.
Scan the complete notarized document in colour.
Keep the original in a safe place.
Preserve the draft, source documents, proof of filing, delivery receipts, and correspondence with the recipient.
Do not change the affidavit after notarization. A material correction generally requires a corrected document and a new notarial act.

Under the 2025 amendments to the 2004 Notarial Rules, notaries must retain prescribed electronic copies and comply with digital reporting. Where the notary and signatory agree to electronic transmittal, the notary must send the signatory an electronic copy without an additional digitization or transmission charge, generally within five days after completion of the notarial act. A signatory may waive that transmittal. Promptly report any material discrepancy between the paper document and the electronic copy.

Special affidavits may have additional rules

Judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. Under the Judicial Affidavit Rule, it must generally contain consecutively numbered questions and answers, required witness information, identification of exhibits, a jurat, and the sworn attestation of the lawyer who conducted or supervised the examination.

The general filing deadline is no later than five days before the pre-trial, preliminary conference, or scheduled hearing on a motion or incident. In covered criminal cases, the prosecution follows the five-day deadline; an accused who elects to submit judicial affidavits generally has 10 days from receipt of the prosecution’s affidavits.

Late submission is ordinarily deemed waived. The court may allow late submission only once when there is a valid reason and no undue prejudice, subject to a discretionary fine of ₱1,000 to ₱5,000. These rules should be applied with counsel because the court’s orders and case type may affect the required procedure.

Complaint-affidavits and counter-affidavits in preliminary investigation

Under Section 3, Rule 112 of the Rules of Criminal Procedure:

A complaint must include the complainant’s and witnesses’ affidavits and supporting documents.
The required copies are generally one for each respondent plus two for the official file.
Affidavits should be sworn before a prosecutor or authorized government officer or, when those officers are absent or unavailable, before a notary public.
The administering officer must certify personal examination of the affiants and satisfaction that they voluntarily executed and understood the affidavits.
A respondent generally has 10 days from receipt of the subpoena and supporting papers to submit counter-affidavits and supporting evidence.

Do not treat a generic affidavit template as an adequate complaint-affidavit or counter-affidavit without checking the applicable prosecutor’s requirements.

Signature by mark or physical inability to sign

The Notarial Rules contain special safeguards for a person who signs by thumbmark or other mark or who is physically unable to sign. These procedures involve the notary and disinterested witnesses and require specific statements in the document. Do not ask another person to sign informally on the affiant’s behalf.

Tell the notary beforehand about blindness, limited literacy, hearing or speech disability, difficulty understanding the document’s language, or physical inability to sign. The notary must ensure that the affiant understands the document and acts voluntarily.

Affidavits executed abroad

A person abroad may generally use one of these routes, subject to the receiving authority’s requirements:

Execute the affidavit before a Philippine Embassy or Consulate providing notarial services.
Execute it before a qualified foreign notary and obtain an apostille from the competent authority if the country is an Apostille Convention party.
Follow the applicable authentication or legalization process if the country or document is not covered by the Apostille Convention.

An apostille authenticates the origin of the public document, signature, and official capacity; it does not certify that the affidavit’s factual contents are true. Check the destination-specific process through the DFA Apostille Service and the relevant Philippine foreign-service post before signing.

Electronic and remote notarization

The Rules on Electronic Notarization supplement paper notarization. They cover electronic documents processed through a Supreme Court-accredited Electronic Notarization Facility by a commissioned Electronic Notary Public.

They provide for:

In-person electronic notarization, where the parties physically appear but execute an electronic document; and
Remote electronic notarization through synchronous videoconferencing and the approved facility.

For an electronic jurat, the principal must electronically sign through the approved facility in the notary’s view and take the oath. Pre-recorded videos are not a substitute for the live session.

The rules do not cover paper documents with wet signatures, depositions, or notarial wills. A principal outside the Philippines may use remote electronic notarization only under the limited extraterritorial procedure, including physical presence at a Philippine embassy, consular office, or honorary consul’s office and confirmation by a designated officer.

Do not assume that a video call, emailed scan, pasted digital seal, or commercial “online notary” is valid. Confirm that the lawyer has an electronic notarial commission and that the platform is Supreme Court-accredited. Check the Supreme Court’s eNotary Services page for current implementation and directory availability.

The 2020 interim rules for remote notarization of paper documents were designed for areas under pandemic community quarantine. They should not be treated as a permanent general authorization to notarize wet-signed documents through an ordinary video call. See the 2020 Interim Rules.

Deadlines and validity

There is no universal rule that every affidavit expires after three or six months. Its usefulness depends on:

The date-sensitive facts it states.
The law or agency requiring it.
A deadline in a court order, contract, notice, or application.
A recipient’s stated recency requirement.
Whether circumstances have materially changed since execution.

Notarization also does not extend a filing deadline. An affidavit signed on time but filed late may still be rejected.

Always identify the intended use before drafting. Passport, civil-registry, immigration, insurance, banking, employment, land, and court matters may each impose different forms and deadlines.

Evidentiary limits

A notarized affidavit is not automatically proof that every statement is true. In an ordinary court trial, an affidavit offered to prove its contents may remain hearsay if the affiant does not testify and the opposing party has no opportunity to cross-examine, unless a rule or recognized exception permits its use. The Supreme Court explains this distinction in People v. Brioso, G.R. No. 220977.

Different standards may apply in preliminary investigations, labor cases, administrative proceedings, summary proceedings, and other processes where affidavits are expressly accepted. Admissibility and weight therefore depend on the forum, purpose, governing rules, and opportunity to test the statement.

Common mistakes and red flags

Avoid:

Signing before meeting the notary for a jurat.
Allowing someone else to appear for the affiant.
Using only a cedula as identification.
Leaving material blanks in the affidavit or jurat.
Using a photocopied, pre-signed, or pre-stamped notarial page.
Notarization by a secretary while the lawyer is absent.
Backdating or using a false venue.
Altering the affidavit after notarization.
Stating rumors as established facts.
Omitting important qualifications that make a statement misleading.
Attaching cropped or edited evidence without preserving the original.
Assuming notarization makes an invalid agreement valid.
Assuming a scanned wet-signed affidavit is electronically notarized.
Paying for a stamp without taking an oath.
Ignoring the recipient’s prescribed form, attachments, copy count, or deadline.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The affidavit concerns a criminal complaint, counter-affidavit, arrest, subpoena, or prosecutor’s deadline.
A court deadline is approaching or has passed.
You are being asked to admit liability, waive rights, transfer property, surrender custody, or withdraw a complaint.
The affidavit concerns land, inheritance, corporate authority, substantial money, immigration status, or family rights.
Someone forged your signature or notarized a document without your appearance.
You were pressured, threatened, deceived, or made to sign a document you did not understand.
A notary backdated the document, used a false venue, or left the certificate incomplete.
Two versions of the notarized document differ.
A foreign authority has rejected the document.
You discover a material error after filing.

Preserve the original document, envelopes, receipts, messages, emails, CCTV information, witness details, electronic files, and any copy of the notarial register entry. Do not write on or alter the disputed original.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily sworn before a notary or another officer authorized to administer the oath. An unsigned or unsworn statement may still be useful for some informal purposes, but it is not a properly sworn affidavit unless the applicable law recognizes another method.

Do I need a lawyer to draft an affidavit?

Not always. A simple affidavit may use an official form or a carefully prepared factual statement. Legal assistance is advisable when rights, deadlines, contested facts, criminal exposure, property, or court proceedings are involved. A judicial affidavit requires a lawyer’s examination and sworn attestation.

Can I sign the affidavit before going to the notary?

For a paper jurat, no. The affiant must sign in the notary’s presence. An acknowledgment follows a different procedure, but personal appearance remains mandatory.

Can a notary accept a photocopy or picture of my ID?

The notary must reliably verify identity through competent evidence. Bring the original current ID. A notary may retain a copy for the record, but a photograph alone should not be assumed sufficient.

Can I use a cedula?

Not by itself. A community tax certificate lacks the photograph-and-signature safeguards required for competent evidence of identity.

Can my representative have my affidavit notarized?

No one may personally appear, sign, or take the oath in place of the named affiant. A representative may execute a different affidavit in the representative’s own capacity where the law and receiving authority permit it.

Can an affidavit be notarized online?

Only through the procedures allowed by the Rules on Electronic Notarization, using a commissioned Electronic Notary Public and an accredited facility. An ordinary video call or emailed scan is not enough.

Does a notarized affidavit expire?

There is no universal expiration period under the general Notarial Rules. The receiving institution may require a recently executed affidavit, and changed facts can make an older affidavit inaccurate or unusable.

Is a notarized affidavit automatically accepted in court?

No. Notarization addresses execution and authenticity; admissibility, relevance, hearsay, personal knowledge, and cross-examination remain separate questions.

What if the affidavit contains an error?

Correct it before signing. If a material error is found after notarization, do not erase, overwrite, or replace pages. Prepare a corrected or supplemental affidavit and have it properly notarized, then follow the receiving authority’s procedure for replacing or supplementing the earlier filing.
