Quick answer

An affidavit is a written statement of facts that the person making it—the affiant—swears or affirms is true before a notary public or another officer legally authorized to administer oaths. For an ordinary paper affidavit in the Philippines, the affiant generally must:

Complete the affidavit without material blanks.
Personally appear before the notary.
Present competent evidence of identity, unless personally known to the notary.
Sign the affidavit in the notary’s presence.
Take an actual oath or affirmation as to its contents.
Sign the notarial register.
Ensure that the notary completes the jurat, signs it, affixes the official seal, and enters the proper notarial details.

A notarial stamp alone does not make an affidavit valid. Sending a signed document or ID photograph to a notary is not valid paper notarization. Remote electronic notarization is possible only under the Supreme Court’s formal electronic-notarization system—not through an informal video call or emailed scan.

Specific affidavits may have additional forms, attachments, deadlines, witnesses, or administering-officer requirements. Always check the rules of the court, prosecutor, bank, school, registry, or government agency that will receive the document.

What makes a document an affidavit?

A valid affidavit ordinarily has three essential features:

It contains statements of fact attributed to an identified affiant.
The affiant signs it and swears or affirms that its contents are true.
An authorized officer administers the oath and certifies that act through a jurat.

A document called an “affidavit” but merely signed in private is ordinarily an unsworn statement, unless a particular law or rule expressly permits an unsworn declaration or another form of certification.

Notaries public are not the only officers who may administer oaths. The Administrative Code, as amended, gives that authority to specified public officers, including members of the judiciary, clerks of court, certain national and local officials, Public Attorney’s Office lawyers in connection with their duties, and notaries public. Except for notaries and certain court officers, a public officer’s authority is generally exercised in official business or in relation to that officer’s functions. See Section 41 of the Administrative Code, as amended.

A special law or procedural rule may require the affidavit to be sworn before a particular officer. A general authority to administer oaths does not override that specific requirement.

Jurat versus acknowledgment

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

Notarial act	What the signer does	Must the document be signed before the notary?
Jurat	Signs and takes an oath or affirmation that the document’s contents are true	Yes
Acknowledgment	Declares that an existing signature was voluntarily affixed and that the document is the signer’s free act and deed	Not necessarily; the signature may have been affixed earlier
Signature witnessing	Signs a document while the notary watches	Yes, but no oath concerning the truth of the contents is inherent in this act

A jurat usually begins with wording such as “Subscribed and sworn to before me.” That wording is not enough by itself: the affiant must actually appear, sign in the notary’s presence, and take the oath or affirmation.

If an affidavit was signed beforehand, the notary should require proper execution in the notary’s presence. Do not ask the notary simply to stamp a previously signed affidavit.

What the affidavit should contain

There is no single form for every affidavit. A well-prepared general affidavit ordinarily includes:

The appropriate venue, such as the Republic of the Philippines and the city or province where the oath will actually be administered.
A clear title identifying the affidavit’s purpose.
The affiant’s complete legal name and enough identifying information for the intended transaction.
Numbered paragraphs stating relevant facts clearly and chronologically.
Facts within the affiant’s personal knowledge, with the source identified when a procedural rule permits information based on records or other sources.
Accurate references to supporting documents.
A statement explaining why the affidavit is being executed.
The affiant’s signature over the printed name.
The correct jurat, to be completed by the administering officer.

Use the receiving office’s prescribed form when one exists. An affidavit of loss, complaint-affidavit, judicial affidavit, affidavit of support, affidavit concerning civil-registry records, and affidavit required for a property transaction may have very different legal requirements.

Write only what the affiant can truthfully swear to. Distinguish clearly among:

What the affiant personally saw, heard, did, or received;
What a record shows;
What another person allegedly said; and
What the affiant merely believes or concludes.

Avoid legal conclusions, exaggeration, guesses, and statements copied from another person’s affidavit without verification.

Competent evidence of identity

Under the paper-notarization rules, identity may generally be established through at least one current identification document issued by an official agency and bearing the individual’s photograph and signature.

Bring the original ID, not merely a photograph or photocopy. A notary may reasonably request another ID or supporting civil-registry document when:

The name, photograph, signature, birth date, or other details do not match;
The ID is damaged, expired, or difficult to verify;
The document uses a married, former, or differently spelled name; or
Circumstances create reasonable doubt about identity.

Because some newer government credentials do not display a handwritten signature, contact the notary beforehand and, where possible, bring another current official ID bearing both photograph and signature.

A community tax certificate or cedula, standing alone, is not competent evidence of identity under the Notarial Rules. The Supreme Court has repeatedly disciplined notaries for relying on it as the sole identification document. See the Court’s ruling on mandatory compliance with competent-identification requirements.

If the affiant has no qualifying identification document, the rules provide a credible-witness route:

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.

This is not a shortcut for an inconvenient or expired ID. The notary must be satisfied that all requirements are met and may decline the notarization if identity remains uncertain.

The proper paper-notarization process

1. Confirm the recipient’s requirements

Before drafting, obtain the latest official form or checklist. Ask whether the receiving office requires:

A recently executed affidavit;
Particular wording or facts;
Original supporting documents or certified copies;
Photographs, fingerprints, or independent witnesses;
A specific number of originals or copies;
A particular administering officer; or
Filing, tax, documentary-stamp, or authentication requirements.

There is no universal validity period for all affidavits. An agency may require a recently executed document even though Philippine law does not give that type of affidavit a general expiration date.

2. Complete and review the document

Do not present a blank or materially incomplete document for notarization. Check:

Names and name suffixes;
Dates, places, addresses, and amounts;
Identification and reference numbers;
Page and exhibit references;
Spelling of persons and entities; and
Consistency with attached records.

Cross out unused spaces where appropriate. Do not insert material statements after notarization. If a material correction is needed, the safer course is usually to prepare and execute a corrected affidavit.

3. Appear personally

For ordinary paper notarization, the affiant must be physically present before the notary at the time of the notarial act. A relative, employee, messenger, or lawyer cannot appear and take the oath for the affiant.

The notary must be commissioned for the place where the act is performed and must observe the territorial and workplace restrictions in the Notarial Rules.

4. Present identification

Show the original competent evidence of identity. The notary records the necessary identification information in the notarial register. Protect unnecessary personal data, but do not obstruct the notary’s required identity and recordkeeping checks.

5. Sign and take the oath or affirmation

Sign the affidavit while the notary is present. The notary must administer a meaningful oath or affirmation. The affiant should understand that false material statements can carry criminal consequences.

A person who does not wish to take a religious oath may make a solemn affirmation. It has the same legal effect.

6. Complete the notarial register

The affiant must sign or place the required mark in the notarial register. The notary records information including the date and time, type of act, document description, principal’s identity, fee, and other required details.

7. Inspect the completed jurat

Before leaving, confirm that the jurat shows the actual date and place of notarization and contains the notary’s:

Signature and official seal;
Name as stated in the commission;
Commission and territorial information;
Office address and required professional details; and
Document, page, book, and series entries.

Do not accept a materially blank certificate or agree to backdating. The date must reflect when the affiant actually appeared and took the oath.

The governing rules are the 2004 Rules on Notarial Practice, read together with the Supreme Court’s 2025 amendments, which strengthened electronic recordkeeping and reporting safeguards for paper notarizations.

When the notary must or may refuse

A notary should not proceed when, among other reasons:

The affiant is absent or cannot be properly identified;
The document is blank or incomplete;
The requested act or transaction appears unlawful or immoral;
The affiant does not appear to understand the consequences;
The affiant is acting under coercion or without free will;
The notary cannot communicate adequately with the affiant;
The notary is a party, has a prohibited financial interest, or has a disqualifying family relationship with the principal; or
The requested act is outside the notary’s authority or territorial jurisdiction.

A stamp-for-a-fee transaction without identity verification, personal appearance, signing, and an oath is not lawful notarization.

Affiants who sign by mark or cannot physically sign

A person who signs by thumbmark or another mark must do so in the notary’s presence and in the presence of two disinterested and unaffected witnesses. The witnesses must sign, and the notary must make the notation required by the Rules.

Where a person is physically unable to sign or make a mark, the Rules provide a separate procedure under which the notary may sign on that person’s behalf at the person’s direction, in the presence of two disinterested and unaffected witnesses, with the required notation.

These procedures should not be improvised. Arrange them with the notary in advance, especially when the affiant is hospitalized, has a disability, or needs language assistance. The affiant must still have the capacity to understand the affidavit and act voluntarily.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization took effect in March 2025. They recognize:

In-Person Electronic Notarization (IEN): the principal physically appears before an Electronic Notary Public, but the document and notarial process are electronic;
Remote Electronic Notarization (REN): appearance occurs through compliant real-time videoconferencing and prescribed identity, location, signing, security, and recordkeeping controls; and
A permitted combination of electronic methods under the Rules.

Only a properly commissioned Electronic Notary Public using an authorized or accredited Electronic Notarization Facility may perform these acts. A regular notary cannot convert paper notarization into remote notarization by using an ordinary Zoom, Messenger, Viber, or similar call.

For an electronic jurat, the affiant must electronically sign in the Electronic Notary Public’s presence and take the oath or affirmation. REN must be synchronous; a prerecorded video, emailed signature page, or scanned paper affidavit is insufficient.

Participants in REN generally must be physically located in the Philippines. The Rules contain a limited extraterritorial procedure for a principal abroad at specified Philippine diplomatic or consular premises. Check the Supreme Court’s official eNotary FAQs and confirm that the intended recipient accepts the resulting electronic document.

Affidavits executed abroad

A person abroad generally has two conventional options, subject to the receiving office’s rules:

Execute the affidavit before an authorized officer at a Philippine embassy or consulate; or
Execute it before a competent local notary or official and obtain an apostille from the foreign country’s designated authority if that country is a party to the Apostille Convention.

For a non-Apostille country, the applicable authentication or legalization chain may still be required. Requirements vary by country and by Philippine receiving agency.

An apostille authenticates the origin of the foreign public document, such as the capacity and signature of the foreign notary. It does not certify that the affidavit’s factual statements are true. Consult the relevant Philippine foreign service post and the receiving office before signing.

Special procedural affidavits

Judicial affidavits

A judicial affidavit is not an ordinary narrative affidavit. It generally contains consecutively numbered questions and answers, identifies how the witness acquired knowledge of the facts, authenticates exhibits, and includes both the witness’s jurat and the examining lawyer’s sworn attestation.

Under the Judicial Affidavit Rule, the general filing deadline is no later than five days before the pretrial, preliminary conference, or scheduled hearing for the relevant motion or incident. Criminal cases have additional coverage and timing rules.

Late submission is generally treated as a waiver. A court may allow it only once when the stated conditions are satisfied, including a valid reason, lack of undue prejudice, and payment of the prescribed ₱1,000 to ₱5,000 fine. Do not use a generic affidavit in place of a judicial affidavit.

Complaint-affidavits and counter-affidavits in preliminary investigation

Under Rule 112 of the Rules of Criminal Procedure, affidavits for preliminary investigation should be subscribed and sworn before a prosecutor or government official authorized to administer oaths. Only in their absence or unavailability may a notary public ordinarily perform the act. The administering officer must certify that the affiants were personally examined and voluntarily executed and understood their affidavits. See the Rules of Criminal Procedure.

The prosecutor’s subpoena and applicable prosecution rules may impose short, non-extendible or conditionally extendible periods. Seek advice immediately rather than relying on the date of notarization.

What notarization does—and does not do

Proper notarization converts a private document into a public document for evidentiary purposes and gives rise to a presumption concerning its due execution and authenticity.

It does not:

Prove that every factual statement is true;
Cure forgery, fraud, incapacity, illegality, or lack of authority;
Make an otherwise invalid transaction valid;
Guarantee acceptance by a court or government agency; or
Automatically make the affidavit admissible for every evidentiary purpose.

The Supreme Court has clarified that notarized documents are generally prima facie evidence of due execution and authenticity, not automatically of the truth of their contents. See G.R. No. 253527, October 21, 2024.

An ordinary affidavit may also be hearsay when offered to prove its contents if the affiant does not testify and cannot be cross-examined, unless a procedural rule or exception permits its use.

Defective notarization may strip a document of its public character and reduce it to a private document requiring proof of due execution and authenticity. Whether the underlying act remains valid depends on the governing law. Some transactions remain binding between the parties despite defective notarization; others require a public instrument or another solemn form for validity, enforceability, registration, or effect against third persons. The answer cannot safely be generalized from affidavits to deeds, donations, powers of attorney, wills, or property instruments.

False statements and perjury

A knowingly false statement does not become true because it was notarized. Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, punishes a person who knowingly makes an untruthful statement under oath or in an affidavit concerning a material matter before a competent officer when the statement is required by law or made for a legal purpose.

The offense requires more than an innocent mistake. Materiality, deliberate falsehood, the authority of the administering officer, and the legal purpose or requirement must be established. Where the statutory elements are proved, the prescribed principal penalty is prisión mayor in its minimum period, or six years and one day to eight years, with additional consequences for a responsible public officer or employee.

Correct a genuine mistake promptly. Do not alter an already notarized affidavit privately; ask the recipient and a lawyer whether a supplemental, corrective, or newly executed affidavit is appropriate.

Evidence to preserve

Keep:

The final notarized original and a clear complete copy;
The electronic original, validation data, and transmission record for an electronic notarization;
The form or checklist supplied by the receiving office;
IDs and civil-registry records used to resolve name discrepancies;
Every exhibit in the form referred to in the affidavit;
Emails, messages, receipts, photographs, logs, and source records supporting the statements;
Proof of filing or delivery, including the date, time, recipient, and reference number; and
The notary’s receipt and contact or office information.

Preserve original electronic files and their metadata. Repeatedly printing, scanning, or editing a file may make later authentication more difficult.

Common mistakes

Signing before meeting the notary;
Using an acknowledgment instead of a jurat;
Treating a cedula as sufficient identification;
Leaving dates, names, exhibit labels, or material paragraphs blank;
Using a notary whose commission has expired or who is acting outside the authorized territory;
Paying someone to obtain a stamp without personal appearance;
Backdating the affidavit;
Copying facts the affiant does not personally know;
Attaching altered, incomplete, or unrelated exhibits;
Assuming notarization proves the truth of the contents;
Using a generic affidavit where an agency-prescribed or judicial form is required;
Missing the filing deadline while focusing only on notarization; and
Assuming an emailed scan or informal video call is electronic notarization.

When legal help is urgent

Consult a lawyer promptly if:

A court, prosecutor, disciplinary body, or regulator has imposed a deadline;
The affidavit concerns an arrest, criminal complaint, counter-affidavit, domestic violence, child safety, or a threatened loss of liberty;
It affects land, inheritance, corporate authority, a large financial obligation, or a power of attorney;
Another statement, pleading, record, or prior affidavit contradicts what you are being asked to sign;
Someone is pressuring you to omit facts, sign blanks, backdate, or use another person’s identity;
The affiant may lack capacity, cannot communicate reliably, or is seriously ill;
The signature or notarization is alleged to be forged or fictitious;
The document must be used abroad or was executed abroad; or
A receiving office has rejected the affidavit and the filing period is running.

Frequently asked questions

Does every affidavit have to be notarized?

An affidavit must be sworn or affirmed before an officer authorized to administer the required oath. That officer is often a notary, but a statute or procedural rule may authorize or require a prosecutor, clerk of court, consular officer, PAO lawyer, or another public official.

Can a notary notarize an affidavit that I already signed?

A jurat requires signing in the notary’s presence. Expect to execute a fresh copy or follow the notary’s lawful procedure; an acknowledgment is not a substitute for the required jurat.

Is personal appearance always required?

Physical personal appearance is required for ordinary paper notarization. Compliant REN permits remote appearance only through the formal electronic-notarization framework and its safeguards.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity under the Notarial Rules.

Does an affidavit expire?

There is no single expiration period for all affidavits. The receiving office may require a recently executed affidavit or impose a transaction-specific filing deadline.

Must an affidavit be in English?

Not necessarily. The affiant must understand the document and communicate adequately with the administering officer. Judicial affidavits have specific language and translation requirements. The recipient may also require English, Filipino, or a certified translation.

Does notarization prove that the statements are true?

No. It authenticates the notarial act and supports due execution and authenticity. The facts may still be challenged and must satisfy the applicable rules of evidence.

How much does notarization cost?

There is no reliable universal price for every affidavit. Cost may depend on the document, location, professional work involved, electronic facility, and separate government or authentication charges. Agree on the fee beforehand and request a receipt. A fee does not excuse any legal requirement.

Can I use a photocopy or scanned notarized affidavit?

That depends on the recipient. A scanned copy does not become an electronic notarization merely because it was emailed. Courts, banks, registries, and agencies may require the paper original, a certified copy, or the authentic electronic original.
