Quick answer

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

Review and understand the complete affidavit.
Personally appear before a duly commissioned notary public or another officer legally authorized to administer the oath.
Present acceptable proof of identity unless personally known to the notary.
Sign the affidavit in the officer’s presence.
Swear or affirm that its material statements are true.
Ensure that the notary completes and signs the jurat, records the act, and places the required seal and commission details on the document.

Do not sign an affidavit in advance unless the notary specifically directs a lawful procedure. Do not ask another person to bring a pre-signed affidavit for notarization. A notary cannot lawfully certify that you appeared, signed, and took an oath when you did not.

Electronic notarization is now legally recognized, including qualifying remote electronic notarization, but only through a duly commissioned Electronic Notary Public and the Supreme Court’s authorized electronic-notarization system. Sending a signed scan to an ordinary notary by email or video call does not, by itself, create a valid electronic notarization.

What makes a document an affidavit?

An affidavit normally contains:

The affiant’s full name and relevant personal details
Clear, numbered statements of facts
An explanation of how the affiant personally knows those facts
References to supporting documents, where appropriate
The affiant’s signature
A jurat completed by a notary or other authorized officer

The statements should be factual, specific, and based on personal knowledge. If information came from records or another person, identify the source instead of presenting it as something personally witnessed.

An affidavit is different from an unsworn written statement because the affiant makes it under oath or solemn affirmation. Knowingly making a materially false statement in an affidavit may result in prosecution for perjury when the elements of the offense are present. Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, governs perjury in affidavits and other sworn statements.

Jurat versus acknowledgment

Affidavits ordinarily require a jurat, not merely an acknowledgment.

In a jurat, the affiant:

Personally appears before the notary
Signs the affidavit in the notary’s presence
Takes an oath or affirmation that the statements are true

The jurat commonly uses wording such as “subscribed and sworn to before me,” followed by the date, place, identification details, and the notary’s particulars.

An acknowledgment serves a different purpose. It is commonly used for deeds, contracts, powers of attorney, and similar instruments. The signer personally appears and declares that the signature is voluntary and that the document is the signer’s free act and deed. If signing for a company or another person, the signer also represents having authority to do so.

The Supreme Court has emphasized this distinction: jurats apply to sworn affidavits and pleadings, while acknowledgments concern the voluntary execution of deeds or instruments. See G.R. No. 203990, August 19, 2020 and A.C. No. 10315, January 22, 2020.

Changing the notarial wording cannot cure a document that was executed using the wrong legal form. Certain transactions also have special statutory formalities, so the receiving office’s template and the governing law must be checked.

Personal appearance is essential

For traditional notarization, the signer must personally appear before the notary at the time of the notarial act. The notary must not notarize when the signer:

Is absent
Sends only a signed document through a relative, employee, fixer, or courier
Appears only in a recording or ordinary, unofficial video call
Cannot be properly identified
Does not understand or freely execute the document

The Supreme Court has repeatedly treated notarization without the signer’s personal appearance as a serious violation. The governing requirement appears in the 2004 Rules on Notarial Practice and is applied, for example, in A.C. No. 12798, February 3, 2021.

A secretary or paralegal may help prepare or receive papers, but only the commissioned notary may perform the notarial act. Never leave a document to be “notarized later” without appearing before the notary through the legally permitted method.

Identification requirements

Unless the affiant is personally known to the notary, identity must be established through competent evidence of identity.

Under the amended definition in A.M. No. 02-8-13-SC, this generally means at least one current identification document issued by an official agency that bears the individual’s photograph and signature. The Supreme Court’s nonexclusive examples include passports, driver’s licenses, PRC IDs, government-office IDs, SSS cards, GSIS e-cards, senior-citizen cards, seaman’s books, and other qualifying official identification. See the Supreme Court’s 2008 amendment on competent evidence of identity.

Bring the original ID, not merely a photograph or photocopy. Check that:

The ID is current and readable.
The name reasonably matches the affidavit.
The photograph and signature identify the affiant.
Any difference in name is supported by appropriate records, such as a marriage certificate or civil-registry document.

A community tax certificate or cedula alone is not a reliable substitute for the current official photo-and-signature identification required by the amended Rules. The Supreme Court has specifically addressed improper reliance on cedulas in A.C. No. 11889, November 27, 2024.

The Rules also recognize identification through qualifying credible witnesses in appropriate circumstances. This is not simply permission to bring any friend or relative. The notary must determine that all requirements for credible-witness identification are met.

What to bring to the notary

Prepare the following:

The complete affidavit, with no material blank spaces
Your original current government-issued photo-and-signature ID
Supporting records referred to in the affidavit
Originals and copies of documents that must be attached
Proof explaining any name discrepancy
Proof of authority if signing in a representative capacity
Any prescribed form or instructions from the court, agency, employer, school, bank, or foreign recipient

Ask the receiving office in advance whether it requires multiple originals, identification-number redaction, a specific jurat, witnesses, photographs, fingerprints, documentary stamps, authentication, apostille, or a filing deadline. Those are document- or agency-specific requirements, not universal requirements for every affidavit.

A safe step-by-step process

1. Confirm the required document

Find out whether the recipient actually requires:

An affidavit with a jurat
A declaration or certification
A deed or contract with an acknowledgment
A judicial affidavit
A special agency form
Consular notarization or an apostille for overseas use

The title placed on a document does not determine its legal character. Its substance and the applicable law do.

2. Write only facts you can support

Use exact names, dates, addresses, amounts, document numbers, and events. Separate personal knowledge from information learned through records or other people. Avoid legal conclusions unless a lawyer has advised that they are necessary.

Do not guess merely to complete a form. If a fact is unknown, verify it or explain the limitation accurately.

3. Review the final version before signing

Correct all errors before notarization. Remove unfilled material blanks and verify that every attachment is correctly identified. If a document has several pages, keep them together and ask whether initials, page numbering, or other safeguards are required.

4. Appear before the proper notary or authorized officer

Confirm that the notary has a current commission and may act within the territorial jurisdiction of that commission. The notarial certificate should identify the place where the act occurred.

5. Present identification and take the oath

For a jurat, sign in the notary’s presence and answer the oath or affirmation truthfully. If you do not understand the document or the language used, say so before signing. Request an accurate explanation or translation where appropriate.

6. Inspect the completed notarization

Before leaving, check that the affidavit bears:

The completed jurat
The date and place of notarization
The affiant’s identification details where required
The notary’s signature and seal
The notary’s name, commission details, office information, and other required professional details
The document, page, book, and series numbers or other required notarial reference

Do not accept an incomplete notarial certificate or a loose seal and signature with blanks to be filled later.

7. Keep a complete copy and file on time

Make a clear copy of the notarized affidavit and all attachments. Notarization does not file or submit the document for you. Deliver it through the filing method allowed by the receiving court or agency and keep proof of submission.

Paper and electronic notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, recognize:

In-person electronic notarization
Remote electronic notarization
Hybrid electronic notarization, where permitted

Remote electronic notarization requires the principal—and witnesses, if required—to appear virtually through the authorized system and follow its identity-verification, electronic-signature, recording, and document-handling safeguards. It is not the same as emailing a scan or arranging an informal video call.

Use an Electronic Notary Public whose electronic commission is current. Verify the transaction and preserve the electronic notarized document, audit information, and any official verification reference supplied by the system. Consult the Supreme Court’s official electronic-notarization FAQs for current availability and procedures.

Electronic notarization does not apply indiscriminately to every instrument. The Supreme Court identifies exclusions, including notarial wills, depositions, and paper documents that are not converted into qualifying electronic documents under the Rules. If the transaction involves land, succession, corporate authority, family rights, or a foreign recipient, confirm acceptance before relying on electronic notarization.

Judicial affidavits have additional requirements

A judicial affidavit is not merely an ordinary narrative affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, it generally must include:

The witness’s prescribed personal details
The examining lawyer’s name and address and the place of examination
Consecutively numbered questions and answers
Facts showing how the witness acquired personal knowledge
Proper identification and authentication of exhibits
The witness’s signature over the printed name
A jurat
The examining lawyer’s separate sworn attestation

It must be in a language known to the witness. If that language is neither English nor Filipino, an English or Filipino translation must accompany it.

As a general rule, judicial affidavits and exhibits must be filed with the court and served on the adverse party no later than five days before the relevant pre-trial, preliminary conference, or scheduled hearing for motions and incidents. Criminal cases have additional rules and timelines. Late or defective submissions may be excluded, subject only to the limited relief stated in the Rule.

A judicial affidavit should therefore be prepared with litigation counsel. Do not assume that notarizing an ordinary affidavit makes it an acceptable judicial affidavit.

When notarization is—and is not—required

Not every written agreement or statement must be notarized to be valid. Notarization primarily authenticates the notarial act and may convert a qualifying private instrument into a public document for evidentiary purposes. It does not automatically:

Prove that every factual statement in the document is true
Transfer ownership by itself
Cure fraud, forgery, incapacity, lack of consent, or lack of authority
Supply a missing legal requirement
Register a transaction with the government
Make an unlawful agreement enforceable

The Civil Code requires certain acts and contracts to appear in a public document, including those involving the creation, transmission, modification, or extinction of real rights over immovable property and the other matters listed in Article 1358. In many situations, that requirement concerns the document’s efficacy or convenience rather than the underlying agreement’s validity. But some transactions have formalities required for validity. For example, Article 749 requires a donation of immovable property and its acceptance to be made in the prescribed public document. The applicable provisions appear in the Civil Code of the Philippines.

Because the consequences differ by transaction, obtain legal advice before executing a deed of sale, donation, mortgage, extrajudicial settlement, waiver of hereditary rights, special power of attorney, marital-property agreement, or document affecting land.

Affidavits executed outside the Philippines

A person abroad may ordinarily execute an affidavit before an authorized Philippine consular officer or under the legally recognized notarial process of the country where the document is signed.

Whether an apostille, consular action, translation, or other authentication is required depends on:

The country of execution
The authority before whom it was executed
The country where it will be used
The type of document
The requirements of the Philippine court, registry, agency, or private recipient

An apostille authenticates the origin of a public document for use between parties to the Apostille Convention; it does not establish the truth of the affidavit’s contents. Confirm the current procedure with the relevant Department of Foreign Affairs office or Philippine embassy or consulate before signing.

Evidence to preserve

Keep:

The final notarized affidavit and every attachment
A scan showing all pages, seals, signatures, and notarial details
Copies of the ID and authority documents presented, where lawfully retained
Drafts and source records supporting each material statement
Messages or instructions showing why the affidavit was requested
Filing receipts, courier records, emails, and electronic acknowledgments
For electronic notarization, the original electronic file and official verification data
Details of the notary’s office, commission, and the date and place of notarization

Preserve original electronic files rather than relying only on printed copies. Metadata, electronic signatures, and verification information may be lost when a file is printed or resaved.

Common mistakes to avoid

Signing before reaching the notary
Allowing a fixer or office employee to “process” notarization without your appearance
Using an expired, altered, borrowed, or inadequate ID
Leaving names, dates, amounts, property descriptions, or other material terms blank
Attaching documents that are incomplete or different from those described
Using an acknowledgment when a jurat is required, or vice versa
Swearing to matters outside personal knowledge without identifying the source
Copying an affidavit template that does not fit the facts
Backdating or asking the notary to use a false place or date
Assuming notarization automatically files, registers, or legalizes the document
Treating an emailed scan or ordinary video call as electronic notarization
Missing the recipient’s separate filing deadline
Altering the affidavit after notarization

If a material correction is necessary after notarization, prepare and execute a corrected affidavit or another appropriate instrument. Do not erase, replace pages, or insert new terms into the notarized copy.

When legal help is urgent

Consult a Philippine lawyer promptly if:

You are being pressured to sign facts you believe are false or incomplete.
The affidavit may expose you to criminal, civil, tax, immigration, employment, or administrative liability.
Police, prosecutors, investigators, regulators, or a court requested the statement.
The affidavit concerns domestic violence, threats, detention, a child, or immediate personal safety.
A filing or hearing deadline is approaching.
The document affects land, inheritance, marriage, corporate authority, or a substantial amount of money.
Your signature or notarial details appear to have been forged.
A document was notarized without your appearance.
The notary’s commission, register entry, date, location, or identity details appear false.
You need to withdraw, correct, or contradict an affidavit already submitted.

A notary’s role in performing the notarial act is not necessarily the same as giving independent legal advice. If your rights may be affected, consult your own lawyer before signing.

Frequently asked questions

Can I sign the affidavit at home and send it to a notary?

Not under the ordinary paper-based jurat procedure. The affiant must sign in the notary’s presence and take the oath or affirmation. A qualifying remote electronic notarization must instead follow the Supreme Court’s official electronic process.

Is one government ID enough?

Generally, at least one current official identification document bearing the affiant’s photograph and signature may satisfy the rule, unless the notary or receiving institution reasonably requires additional proof. Name discrepancies and unclear or expired IDs may require supporting records.

Is a cedula enough?

A cedula alone should not be treated as competent evidence of identity under the current photo-and-signature identification rule.

Must every affidavit be notarized?

An affidavit is, by nature, a sworn statement and normally needs a jurat from a notary or another officer authorized to administer the oath. Some laws, court rules, or agency processes permit different forms of sworn or verified submission, so follow the rule governing the particular filing.

Does notarization prove that everything stated is true?

No. It authenticates the notarial act and the signer’s appearance, identity, signature, oath, or acknowledgment as applicable. The truth and evidentiary weight of the underlying statements may still be challenged.

Can a notary refuse to notarize?

Yes. A notary should refuse when identity, personal appearance, understanding, willingness, completeness, authority, or legality is doubtful, or when the notary is disqualified by interest or prohibited relationship.

Can a relative notarize my affidavit?

The Notarial Rules disqualify a notary who is a spouse, common-law partner, ancestor, descendant, or relative of the principal within the fourth civil degree of consanguinity or affinity. Use an independent notary.

How long is an affidavit valid?

There is no universal expiration period for all affidavits. Its usefulness depends on the purpose, the receiving office’s rules, and whether its facts remain current. Some agencies require a recently executed affidavit.

Can I change a notarized affidavit?

Do not alter it after notarization. Execute a corrected, supplemental, or new affidavit as appropriate, clearly addressing the earlier statement when necessary.

Where can I complain about improper notarization?

Preserve the document and supporting evidence, then seek advice on submitting a verified complaint to the proper authority, which may include the Executive Judge responsible for notarial commissions or the Supreme Court’s Office of the Bar Confidant. Suspected forgery, falsification, or identity theft may also require immediate advice about criminal and protective remedies.
