Quick answer

An affidavit is a written statement of facts that the affiant swears or solemnly affirms to be true before a person authorized to administer an oath. In the Philippines, it is usually notarized through a jurat: the affiant personally appears before the notary, is properly identified, signs the affidavit in the notary’s presence, and takes an oath or affirmation.

Notarization does not prove that every statement in the affidavit is true. It establishes the circumstances of execution—particularly the affiant’s identity, personal appearance, signature, and oath—and ordinarily converts a properly notarized private document into a public document for evidentiary purposes.

There is no single form, filing deadline, fee, or attachment rule for every affidavit. The office, court, bank, school, employer, or transaction requiring the affidavit may impose additional requirements. Obtain its current checklist before signing or notarizing anything.

What makes a document an affidavit?

A document

Quick answer

An affidavit is a written statement of facts that the affiant swears or solemnly affirms to be true before a person authorized to administer an oath. In the Philippines, it is ordinarily completed through a jurat: the affiant personally appears before the notary public, proves identity, signs in the notary’s presence, and takes an oath or affirmation.

Not every document must be notarized. Notarization is required when a law, court rule, government agency, contract, or receiving institution requires a sworn or notarized document. Even when optional, proper notarization can convert a private document into a public document as to its due execution and give it a presumption of regularity. It does not, however, prove that every factual statement in the affidavit is true.

The controlling framework includes the Supreme Court’s 2004 Rules on Notarial Practice, as amended, and the separate 2025 Rules on Electronic Notarization.

What an affidavit should contain

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

A caption showing the Republic of the Philippines and the city or province where the oath will be administered;
The affiant’s complete name and sufficient identifying details, commonly age or confirmation of legal age, citizenship, civil status, and address when relevant;
A statement that the affiant was duly sworn or solemnly affirmed;
Numbered paragraphs setting out facts clearly and in chronological order;
Only facts within the affiant’s personal knowledge, with the source identified if a statement is based on records or information from another person;
A clear explanation of why the affidavit is being executed;
References to supporting documents, with properly marked attachments when needed;
The affiant’s signature over the printed name; and
A completed jurat signed and sealed by the notary public or other officer authorized to administer the oath.

There is no universal affidavit template. An affidavit of loss, complaint-affidavit, affidavit of discrepancy, affidavit of support, proof-of-service affidavit, judicial affidavit, and affidavit used in a land or corporate transaction may have different mandatory statements and attachments. Obtain the current checklist or prescribed form from the court, agency, embassy, bank, school, employer, or other intended recipient before signing.

Jurat versus acknowledgment

The notarial certificate must match the act being performed.

Jurat

A jurat is normally used for an affidavit. Under the Notarial Rules, the affiant must, on a single occasion:

Appear before the notary;
Present the document;
Be personally known to the notary or properly identified;
Sign in the notary’s presence; and
Take an oath or affirmation concerning the document.

Words such as “subscribed and sworn to before me” ordinarily indicate a jurat. Because signing in the notary’s presence is part of a jurat, do not sign in advance unless the notary specifically confirms that the applicable procedure permits it.

Acknowledgment

In an acknowledgment, the principal appears before the notary, is properly identified, and declares that the signature and execution of the document are voluntary. The document may have been signed earlier. Acknowledgments commonly appear in contracts, deeds, and powers of attorney rather than affidavits.

Using an acknowledgment where a jurat is required may leave the affidavit improperly sworn. Changing only the wording at the bottom of the page does not cure the absence of an oath or the affiant’s required appearance.

Personal appearance is the general rule

For ordinary paper notarization, the affiant must personally appear before the commissioned notary public. Leaving a signed affidavit with a secretary, courier, fixer, friend, or lawyer and collecting it later is not valid personal appearance.

The Supreme Court has repeatedly treated personal appearance as indispensable because it allows the notary to verify identity, observe the signing, administer the oath, and help prevent fraud. A notarization performed without the actual affiant’s appearance may lose its presumption of regularity and can expose the notary to administrative sanctions. See, for example, the Court’s discussion in Gonzales v. Ramos, A.C. No. 7350 and Agadan v. Atty. Kilaan, A.C. No. 10249.

Identification requirements

If the notary does not personally know the affiant, the affiant must present competent evidence of identity.

Under the amended definition in the Notarial Rules, this generally means at least one current identification document issued by an official agency bearing the holder’s photograph and signature. Examples listed by the Supreme Court include a passport, driver’s license, Professional Regulation Commission ID, NBI or police clearance, government employee ID, SSS card, GSIS e-card, PhilHealth card, senior citizen card, seaman’s book, and other qualifying government-issued documents. The controlling definition appears in the Supreme Court’s 2008 amendment to Rule II, Section 12.

A Community Tax Certificate or cedula alone is not competent evidence of identity for this purpose. Bring the original current ID, not merely a photograph or photocopy, unless an applicable electronic-notarization process directs otherwise. A receiving office may separately demand copies or additional IDs even if one qualifying ID is sufficient for the notarial act.

If the affiant has no qualifying identification document, the Rules provide an alternative involving credible witnesses who meet specific conditions, including personal knowledge of the affiant and their own competent evidence of identity. This is not a shortcut that a notary must accept without verification; consult the notary beforehand.

What the notary must check

A notary must refuse or stop the act when the essential requirements are absent. Among other matters, the notary should determine that:

The affiant is personally present through the legally applicable procedure;
The affiant has been properly identified;
The affidavit is complete;
The affiant appears to understand the document and is acting voluntarily;
The affiant signs in the notary’s presence when a jurat is required;
The oath or affirmation is actually administered;
The notarial certificate states the relevant facts and is properly completed;
The act is entered in the notarial register; and
The notary is authorized to perform the act in the relevant territorial jurisdiction.

A notary should not notarize a blank or incomplete document. Blank spaces that could later be filled in should be completed or properly cancelled before notarization. The date, place, document details, and notarial-register information must reflect the actual transaction; backdating or using fabricated register details is improper.

When a notary is disqualified

A notary must not perform a notarial act when the notary:

Is a party to the document;
Will receive a direct or indirect commission, advantage, right, title, interest, cash, property, or other consideration from it beyond the lawful notarial fee; or
Is related to a principal within the fourth civil degree of consanguinity or affinity.

A lawyer who prepared the affidavit is not automatically barred from notarizing it merely for that reason, but conflicts of interest, family relationships, financial interests, and the document’s intended use can require another notary. Using an independent notary is often the safer course where impartiality could reasonably be questioned.

Paper and electronic notarization are different procedures

Conventional paper notarization

This remains the usual method. The affiant appears before a duly commissioned notary, presents the paper affidavit and identification, signs as required, and takes the oath or affirmation.

The notary’s commission is territorial. As a general rule, a notary performs acts within the territorial jurisdiction of the commissioning court and at the notary’s regular place of work or business, subject to limited exceptions under the Rules.

Electronic notarization

The 2025 Rules on Electronic Notarization created a formal system for notarizing electronic documents. Electronic notarization is not simply a video call, a scanned signature, or an emailed photograph of a notarized page.

The act must be performed by a lawyer separately commissioned as an Electronic Notary Public, using the Supreme Court-authorized electronic notarial system and complying with the Rules on identity verification, appearance, electronic signatures, recording, certificates, and document preservation. The Supreme Court maintains official information through its eNotary Services portal.

Before relying on this option, confirm that:

The intended recipient accepts an electronically notarized affidavit;
The selected notary has a current electronic-notary commission;
The document is eligible for electronic notarization;
The affiant can satisfy the system’s identity and appearance requirements; and
Any originals, witnesses, attachments, or additional agency requirements can be handled through the prescribed process.

A PDF produced by scanning an ordinarily notarized paper is not, for that reason alone, an electronically notarized document.

Affidavits signed outside the Philippines

A person abroad should not simply send a signed affidavit to a Philippine notary and ask for a seal. Depending on the country and the receiving authority, the usual lawful routes include:

Executing the affidavit before the appropriate Philippine embassy or consulate; or
Executing it before a competent local notary or official, then obtaining an apostille if the country is a party to the Apostille Convention; or
Following the authentication or legalization process applicable in a non-Apostille country.

An apostille authenticates the origin of the public document, such as the signature and official capacity of the notary or certifying officer. It does not certify that the affidavit’s factual allegations are true.

Requirements differ by country, type of document, and intended Philippine use. Check the specific Philippine embassy or consulate and the receiving Philippine agency before execution. Official information is available through the Department of Foreign Affairs.

A Philippine affidavit intended for use abroad may likewise need DFA apostillization and may be subject to translation, certified-copy, or destination-country requirements.

Does notarization make the affidavit’s contents true?

No. Proper notarization generally gives a document evidentiary standing concerning its execution and creates a rebuttable presumption of regularity. It does not make hearsay admissible, establish personal knowledge, prove an attached document’s authenticity, or prevent another party from disproving the statements.

The Supreme Court has explained that the presumption attached to a notarized document depends on regular notarization and may be overcome by proper evidence. See Spouses Caoili v. Court of Appeals, G.R. No. 238325.

An affidavit is also not always a substitute for testimony. In court, the affiant may still need to appear for cross-examination, and the document remains subject to the Rules on relevance, hearsay, authentication, and admissibility.

Special rules for judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. Under the Supreme Court’s Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it must follow a question-and-answer format and contain prescribed information, including:

The witness’s identifying and occupational details;
The lawyer’s name and address and the place of examination;
A statement that the witness answers under oath and understands the possible liability for false testimony or perjury;
Consecutively numbered questions and answers establishing personal knowledge and relevant facts;
Proper identification and authentication of exhibits;
The witness’s signature;
A jurat; and
The examining lawyer’s required sworn attestation.

Filing and service deadlines depend on the type and stage of the case. The Rule generally requires the parties’ judicial affidavits and exhibits to be filed and served not later than five days before pre-trial, preliminary conference, or the scheduled hearing, subject to special provisions and court orders. In criminal cases, additional timing and constitutional safeguards apply. Late submission may be treated as waived unless the court permits the limited relief allowed by the Rule.

Do not adapt a generic online form for a pending case without checking the governing procedural rule and the court’s current order.

Step-by-step checklist

Before drafting

Ask the intended recipient for its current form, checklist, deadline, and attachment requirements.
Identify the exact facts the affidavit must establish.
Collect records that support each important statement.
Confirm whether the recipient requires a paper original, electronic notarization, apostille, witnesses, photographs, documentary stamps, or certified attachments.
Check whether more than one person must execute the affidavit.

While drafting

Use the affiant’s name exactly as shown on the supporting identification, explaining any material discrepancy.
State facts in short, numbered paragraphs.
Include dates, places, persons, amounts, and document references only when known and relevant.
Distinguish personal knowledge from information learned from records or others.
Mark attachments consistently—for example, “Annex A”—and refer to them in the affidavit.
Remove guesses, exaggerations, legal conclusions presented as facts, and statements the affiant cannot honestly verify.
Leave the jurat for the authorized officer to complete.

At notarization

Bring:

The complete, unsigned affidavit if a jurat will be administered;
The original current government-issued ID bearing a photograph and signature;
The required attachments and, where relevant, their originals;
Any witnesses expressly required by law, the form, or the receiving institution; and
The required number of copies.

Read the final document before signing. Take the oath or affirmation personally. Make sure the notary signs and affixes the seal and that the certificate contains the actual date and place of notarization and the notarial details.

After notarization

Check that no page, attachment, signature, or notarial entry is missing.
Keep the notarized original secure.
Make a clear digital scan of the complete document and every annex.
Obtain an official receipt when available.
Submit through the channel and within the deadline specified by the receiving office.
Preserve proof of filing or delivery, such as a receiving stamp, registry receipt, electronic acknowledgment, or docket entry.

Evidence to preserve

When an affidavit concerns a dispute, loss, threat, accident, transaction, employment matter, family issue, property, debt, or possible criminal complaint, preserve:

The final notarized affidavit and all drafts showing corrections;
Copies of the identification used;
The notary’s name, office address, commission details, and receipt;
Photographs or scans of the complete affidavit and annexes;
Original contracts, receipts, certificates, messages, emails, photographs, recordings, and official records supporting the statements;
Metadata and original electronic files where authenticity may matter;
Names and contact details of witnesses;
Proof of when and where the affidavit was filed or served; and
Any rejection notice or written instruction from the receiving office.

Do not alter an affidavit after notarization. If a material correction is necessary, prepare and properly execute a corrected, supplemental, or replacement affidavit and disclose the earlier version when legally relevant.

Common mistakes

Signing before meeting the notary when a jurat requires signing in the notary’s presence;
Allowing another person to appear for the affiant;
Using a cedula alone as identification;
Presenting an expired, altered, borrowed, or digital image of an ID when the original current document is required;
Leaving material blanks in the affidavit;
Using an acknowledgment instead of a jurat;
Attaching documents after notarization without proper identification or marking;
Stating rumors, assumptions, or legal conclusions as personally known facts;
Omitting an adverse fact because it appears inconvenient;
Using a notary whose commission has expired or who is acting outside the authorized territory;
Asking the notary to backdate the document;
Assuming notarization automatically makes the affidavit admissible or conclusive;
Treating a video call or scanned signature as valid electronic notarization;
Missing a court or agency deadline while trying to correct a defective affidavit; and
Believing that “for whatever legal purpose” can replace the specific statements required by law or the receiving office.

False statements and possible liability

An oath is substantive, not ceremonial. Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, knowingly making an untruthful statement under oath or in an affidavit about a material matter may constitute perjury when the legal elements are present. Other circumstances may also expose a person to liability for falsification, use of falsified documents, fraud, contempt, administrative offenses, or damages.

An honest mistake is not automatically perjury; the offense requires the elements established by law, including a willful and deliberate falsehood on a material matter. Nevertheless, correct a discovered error promptly and seek legal advice before submitting or relying on a defective affidavit.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The affidavit will support or oppose a criminal complaint, arrest, search, protection order, detention, or administrative charge;
A court, prosecutor, police office, NBI, Ombudsman, immigration authority, tax authority, or regulator has imposed a deadline;
You are being asked to admit liability, ownership, parentage, debt, fraud, misconduct, or receipt of money or property;
The affidavit concerns land, inheritance, a deed, corporate authority, a large transaction, or a special power of attorney;
You are unsure whether a statement is based on personal knowledge;
The affidavit conflicts with an earlier statement, pleading, record, or testimony;
Someone asks you to sign a blank document, backdate it, omit a material fact, or appear through another person;
A signature or notarization appears forged, fabricated, or entered in a nonexistent notarial register;
The affiant cannot read, understand, hear, see, communicate, or sign without assistance;
The affiant is abroad and the document has an approaching Philippine deadline; or
An agency or court has rejected the affidavit.

For qualifying individuals who cannot afford private counsel, inquire with the Public Attorney’s Office, an Integrated Bar of the Philippines legal-aid office, a law-school legal clinic, or another authorized legal-aid provider. Representation and eligibility depend on the case and the provider’s rules.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily a sworn statement, so it must be subscribed and sworn or affirmed before an officer authorized to administer an oath. Whether a particular submission must take the form of an affidavit depends on the governing law, rule, form, or recipient’s requirement.

Can I write my own affidavit?

Yes, unless a particular proceeding requires preparation or supervision by a lawyer, as with a judicial affidavit under the Judicial Affidavit Rule. A self-prepared affidavit must still contain accurate facts and satisfy all requirements for its intended use.

Can I use one valid government ID?

Generally, one current official identification document bearing the affiant’s photograph and signature can qualify under the Notarial Rules. A notary or receiving institution may require further documents when identity, authority, capacity, or a name discrepancy must be established.

Is a barangay certificate or cedula enough?

A cedula alone is not competent evidence of identity. A barangay certification is among the examples identified in the amended rule, but it must satisfy the governing definition and the notary must be able to verify it. Ask the notary in advance if this is the only document available.

Can an affidavit be notarized if I already signed it?

For a jurat, the Rules require signing in the notary’s presence. The notary may require a fresh copy or require execution in the manner permitted by the governing rules. Do not simply sign again over the old signature unless instructed through a lawful procedure.

Can a Philippine notary notarize my affidavit through an ordinary video call?

Not merely through an informal video call. Electronic notarization must comply with the 2025 Rules and be performed by a duly commissioned Electronic Notary Public through the authorized system. Conventional paper notarization follows its own appearance requirements.

Does an affidavit expire?

There is no single expiration period for all affidavits. Its usefulness may end because facts have changed, the receiving office requires a recently executed document, a transaction has closed, or a filing deadline has passed. Follow the recipient’s current rule.

How much does notarization cost?

There is no reliable nationwide flat fee for every private notarial act. Charges can depend on the document, location, number of signatories or copies, and applicable local or professional schedules. Ask for the fee before proceeding and request a receipt. Consular and apostille fees follow separate official schedules.

Can a notarized affidavit be corrected by hand?

Do not make a material alteration after notarization. A correction may require a new or supplemental affidavit and a new notarial act. Ask the receiving authority or a lawyer how to address the error without concealing the original statement.

Is a notarized photocopy the same as the original affidavit?

No. A photocopy, certified copy, and notarized original are different. Whether a copy is acceptable depends on the receiving authority and the applicable evidentiary or filing rules.

Does an apostille replace notarization?

No. If the underlying document must first be notarized, that step remains necessary. An apostille authenticates the origin of the public document for use in another Apostille Convention country; it does not verify the truth of the affidavit.
