Quick answer

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

Present a complete affidavit to a duly commissioned notary public.
Personally appear before the notary.
Establish identity—unless personally known to the notary—through competent evidence of identity.
Sign the affidavit in the notary’s presence.
Swear or affirm that its contents are true.
Receive a properly completed jurat, usually beginning with “Subscribed and sworn to before me.”

A representative, messenger, or relative cannot appear and take the oath for the affiant. A cedula or community tax certificate alone is not competent evidence of identity under the current rule. An ordinary video call or emailed scan is also not a substitute for lawful notarization; electronic notarization must follow the Supreme Court’s separate rules and use a commissioned Electronic Notary Public and an accredited facility.

Notarization does not prove that every statement in the affidavit is true, cure legal defects, or guarantee that a court, agency, bank, school, or foreign authority will accept it.

What makes an affidavit different from an ordinary statement?

The defining feature of an affidavit is the oath or affirmation. The affiant accepts legal responsibility for the truth of the material statements in the document.

For this reason, an affidavit ordinarily requires a jurat, not merely an acknowledgment:

In a jurat, the affiant personally appears, signs in the notary’s presence, and swears or affirms that the affidavit is true.
In an acknowledgment, the signer declares that an instrument already bearing the signer’s signature was voluntarily executed. This is commonly used for deeds, contracts, and powers of attorney—not as a substitute for the oath required in an affidavit.

The Supreme Court has described the jurat as the portion in which the notary certifies that the affidavit was sworn before the notary. Personal appearance and the administration of the oath are essential, not ceremonial formalities. See Ulaso v. Bides, A.C. No. 7297.

Does every affidavit have to be notarized?

If a law, court, agency, or transaction requires an affidavit, the document normally must be sworn before a notary public or another officer specifically authorized by law to administer the oath. A signed but unsworn narrative is generally only a written statement, not a completed affidavit.

Exceptions depend on the governing rule. Some proceedings authorize a prosecutor, court officer, consular officer, or other designated official to administer the oath. Judicial affidavits, electronic affidavits, agency forms, election documents, and affidavits executed abroad may also have special requirements.

Conversely, not every letter, authorization, certification, or agreement needs notarization. Always check the recipient’s written requirements before paying for notarization.

What an affidavit should contain

There is no single universal template for all affidavits. Its contents depend on its purpose, but a properly prepared affidavit ordinarily includes:

The correct caption or title.
The affiant’s full legal name and only those personal details relevant to the transaction.
A statement that the affiant was duly sworn.
Numbered paragraphs setting out facts clearly and chronologically.
Facts within the affiant’s personal knowledge, with the source identified if authentic records are being described.
The specific purpose for which the affidavit is executed.
Clear references to attachments, if any.
A signature block for the affiant.
A jurat with the correct place and date of notarization.

Names, dates, addresses, identification numbers, document numbers, and property descriptions should match the supporting records. If two records contain different information, describe each accurately; do not silently choose the version that is more convenient.

An affidavit of discrepancy may explain inconsistent records, but it does not by itself amend a PSA civil-registry record, title, court judgment, government database, or other official record when the law requires a separate administrative or judicial correction process.

Identification requirements

Under the Supreme Court’s 2008 amendment, competent evidence of identity ordinarily means at least one current identification document issued by an official agency bearing the individual’s photograph and signature. Examples include a current passport, driver’s license, PRC ID, or another qualifying government-issued identification document.

The rule also recognizes a credible-witness procedure:

One credible witness who is not involved in the document or transaction may identify the affiant if that witness is personally known to the notary and personally knows the affiant; or
Two credible witnesses, neither of whom is involved in the document or transaction, may identify the affiant if each personally knows the affiant and presents the required documentary identification.

This is not a shortcut for missing or expired identification. Arrange it with the notary beforehand because the precise credible-witness conditions must be satisfied.

A cedula or community tax certificate alone is insufficient. The controlling identification rule is in the Supreme Court’s amendment to Rule II, Section 12.

Step-by-step notarization checklist

Before going to the notary

Ask the recipient for its current checklist. Confirm the required form, number of originals, supporting documents, permissible language, filing deadline, and whether an apostille or other certification is needed.
Review every page. Correct misspellings, inconsistent dates, missing attachments, and unexplained blank spaces.
Do not sign a traditional paper affidavit in advance. A jurat requires execution in the notary’s presence.
Bring the complete document. A notary may not notarize a blank or incomplete instrument or one without an appropriate notarial certificate.
Bring original identification. A screenshot or ordinary photocopy may not permit the notary to establish identity.
Bring proof of authority where relevant. A corporate officer, guardian, administrator, or attorney-in-fact may need a board resolution, secretary’s certificate, court order, special power of attorney, or other authority. Authority to represent someone does not generally authorize the representative to swear to facts known only by that person.

During notarization

The notary should:

Confirm the affiant’s personal appearance and identity.
Examine the complete affidavit and its attachments.
Determine that the affiant understands the transaction and is acting voluntarily.
Witness the affiant’s signature or mark.
Administer an oath or solemn affirmation.
Complete the jurat and enter the act in the notarial register at the time of notarization.

The venue in the jurat must state the place where the notarial act actually occurred—not the affiant’s residence, the location of the property, or the place where the document will be filed.

Before leaving

Check that the affidavit contains:

The correct notarization date and place.
The affiant’s correct name.
Language showing that it was subscribed and sworn to.
The identification information required by the Rules.
The notary’s signature and official seal.
The notary’s commission and jurisdiction details.
The document, page, book, and series numbers.

Request the applicable receipt and keep a complete scan of the finished affidavit. Notaries who charge fees must post their schedule of fees and issue the required BIR-registered receipt under the Notarial Rules.

When a notary must refuse

A notary should not proceed merely because a fee has been offered. Refusal is required or appropriate when:

The affiant is absent or identity cannot be established.
The affidavit is blank, incomplete, or lacks the proper notarial certificate.
The notary knows or has reason to believe that the act or transaction is unlawful or immoral.
The affiant appears not to understand the consequences.
The affiant appears coerced or is not acting freely.
The certificate would contain false information.
The requested date or place is untrue.
The notary is a party to the document or will obtain an improper financial or property interest from it.
The notary is disqualified by the family relationship rules.

The notary also generally acts at the notary’s regular place of work and only within the territorial jurisdiction of the commissioning court. Limited exceptions permit notarization at specified places—such as hospitals or detention facilities—within that jurisdiction. These exceptions do not remove the requirements of personal appearance, identification, understanding, and voluntariness.

Signers who cannot make an ordinary signature

The Rules provide formal procedures for a person who is physically unable to sign, including the use of a thumbmark or other mark and, in appropriate cases, a signature affixed by the notary at the person’s express direction. These procedures require disinterested witnesses and special wording in the document.

Do not improvise this process. Contact the notary in advance so that the necessary witnesses, accessibility arrangements, and certificate language can be prepared. If the signer cannot understand the document, communicate a voluntary decision, or provide the required direction, a different legal arrangement—such as a court-authorized representative—may be necessary.

Paper, remote, and electronic notarization

Traditional notarization of paper documents with handwritten signatures remains governed by the 2004 Rules on Notarial Practice, as amended.

Electronic notarization is a separate process under A.M. No. 24-10-14-SC, the Rules on Electronic Notarization. It may involve in-person or remote electronic notarization, but it must be performed by a properly commissioned Electronic Notary Public through an accredited Electronic Notarization Facility.

A Zoom, Messenger, or similar video call by itself is not compliant electronic notarization. Before relying on an electronic affidavit:

Confirm that the provider, facility, and electronic notary are duly authorized.
Confirm that the intended recipient accepts an electronically notarized document.
Follow the facility’s identity-verification, electronic-signature, recording, and certificate procedures.
Retain the completed electronic document and its verification information.

The Supreme Court maintains an official eNotary Services information page and FAQ.

Affidavits executed abroad or intended for foreign use

A Filipino abroad may be able to execute an affidavit before an authorized Philippine consular officer, subject to that Embassy or Consulate’s appointment, personal-appearance, identification, copy, and fee requirements. Procedures vary by post, so consult the correct post’s current checklist.

Another option may be execution before a local notary in the foreign country, followed by an apostille or authentication process applicable in that country. The Philippine receiving office should confirm what it will accept.

For a Philippine notarized private document intended for use abroad, DFA requirements may include a Certificate of Authority for a Notarial Act (CANA) from the appropriate court before the document can be apostilled. Requirements depend on the document and destination. Check the DFA’s current documentary requirements and Apostille FAQ before filing.

An apostille authenticates the origin of the public or certified document; it does not certify that the affidavit’s factual assertions are true or that the receiving authority must accept them for the intended transaction.

Deadlines and validity periods

There is no universal rule that every affidavit expires after a fixed number of months. Its usefulness may nevertheless be limited by:

A deadline imposed by a statute, court order, agency, contract, or recipient.
A recipient’s requirement that the affidavit be recently executed.
Facts that have changed since execution.
An expired supporting document.
A notarial commission that was invalid on the date of notarization.

Do not backdate, postdate, or alter a notarized affidavit to make it appear timely. If circumstances have materially changed, execute a new and accurate affidavit and disclose the earlier statement where necessary.

What notarization does—and does not do

Regular notarization helps establish identity, personal appearance, the administration of the oath, and due execution. Defective notarization may strip a document of the evidentiary advantages associated with regular notarization. See Spouses Tigno v. Aquino, G.R. No. 129416.

But notarization does not:

Make false statements true.
Prove every assertion without supporting evidence.
Make an unlawful agreement valid.
Establish ownership, authority, parentage, citizenship, or civil status by itself.
Replace testimony or cross-examination when the Rules of Evidence require the affiant to testify.
Guarantee acceptance by a particular recipient.

In litigation, an affidavit may still be treated as hearsay if offered to prove its assertions without the affiant’s testimony, unless a governing rule or recognized exception permits its use. A judicial affidavit has separate requirements and normally serves as direct testimony when the witness appears for cross-examination.

False affidavits and improper notarization

Knowingly making a materially untruthful affidavit under circumstances covered by Article 183 of the Revised Penal Code may constitute perjury. Republic Act No. 11594 increased the penalty to prisión mayor in its minimum period, with a fine of up to ₱1,000,000 and perpetual absolute disqualification from government office as provided in the statute. Liability depends on all elements of the offense, including materiality, knowledge, the authority of the officer, and the legal purpose for which the oath was required. See Republic Act No. 11594.

Forgery, use of a falsified notarized document, or a notary’s false certification may create different criminal, civil, evidentiary, and professional liabilities. The exact offense and penalty depend on the acts proved; an irregularity should not automatically be labeled perjury or falsification without legal assessment.

Evidence to preserve

Keep:

The complete notarized original and a legible color scan.
All attachments exactly as notarized.
The receipt and proof of submission.
The ID used, stored securely.
Source records supporting each material fact.
Drafts and communications showing how the affidavit was prepared.
The notary’s name, office, commission jurisdiction, and register details.
Any authority to sign or act in a representative capacity.
Courier, email, filing, or electronic-platform confirmation.

If you suspect forgery or notarization without your appearance, preserve messages, specimen signatures, travel or location records, and every version of the document. Ask the Office of the Clerk of Court of the commissioning RTC about verifying the notary’s commission and the relevant notarial record.

Common mistakes to avoid

Signing a paper affidavit before meeting the notary.
Sending the affidavit through another person for notarization.
Using only a cedula, expired ID, or ID without the required photograph and signature.
Leaving blanks that can be filled in later.
Using an acknowledgment when a jurat is required.
Stating conclusions or second-hand allegations as personal knowledge.
Referring to attachments that are missing or incorrectly labeled.
Using an incorrect venue or notarization date.
Assuming the notary has verified the truth of every statement.
Assuming an affidavit automatically corrects an official record.
Treating an ordinary video call as remote notarization.
Failing to check the recipient’s form, copies, deadline, or foreign-use requirements.
Paying someone who cannot show a valid notarial commission or proper office details.

When legal help is urgent

Consult a Philippine lawyer promptly if the affidavit concerns:

An imminent court, prosecutor, immigration, election, tax, or administrative deadline.
A criminal complaint, counter-affidavit, recantation, or affidavit of desistance.
Land, titles, inheritance, estate settlement, or a disputed sale.
Child custody, parental consent, support, adoption, or international travel.
A large financial transaction or corporate authority.
Conflicting sworn statements or facts that may expose the affiant to liability.
A signer who may lack capacity or be acting under pressure.
Suspected forgery, identity theft, or notarization without personal appearance.
A document that must be used abroad on a fixed date.

Do not sign first and seek advice afterward when the affidavit may waive rights, admit liability, accuse someone of a crime, or contradict an earlier statement.

Frequently asked questions

Can I sign an affidavit before going to the notary?

For a traditional paper affidavit with a jurat, no. The affiant must execute it in the notary’s presence and take the oath or affirmation.

Is a cedula enough for notarization?

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

Can my spouse or representative have my affidavit notarized for me?

No. The person making the sworn statements must personally appear. A power of attorney does not transfer personal knowledge or allow another person to take the affiant’s oath.

Can the notary notarize an affidavit with blank spaces?

No. A blank or incomplete instrument may not be notarized. Mark genuinely inapplicable fields as “N/A” where appropriate instead of leaving material blanks.

Does a notarized affidavit automatically win a case?

No. Its weight depends on relevance, personal knowledge, supporting evidence, admissibility, credibility, and the opportunity for cross-examination.

Can an affidavit be notarized online?

Only through the process allowed by the Rules on Electronic Notarization, using an authorized Electronic Notary Public and accredited facility. An ordinary video call or scanned signature is insufficient.

How long is a notarized affidavit valid?

There is no single universal expiration period. The receiving office may require a recently executed affidavit, and changed facts may make an older affidavit inaccurate or unacceptable.

Can a notary change my affidavit?

A lawyer may help draft or correct it, but the affiant must review and adopt the final statements as true. No notary should insert facts the affiant has not confirmed or alter the completed affidavit after notarization.
