Quick answer

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

State facts truthfully and, as far as possible, from personal knowledge.
Bring the complete, unsigned affidavit and all referenced attachments.
Personally appear before a duly commissioned notary public.
Prove identity through competent evidence of identity, unless personally known to the notary.
Sign the affidavit in the notary’s presence.
Take an oath or affirmation that the statements are true.
Ensure that the notary completes the jurat, signs it, affixes the official seal, and records the act in the notarial register.

A notary cannot lawfully notarize an affidavit merely because someone delivered it, emailed a scan, or showed the signer through an informal video call. Electronic and remote notarization are possible only through the system authorized by the Supreme Court’s Rules on Electronic Notarization.

Notarization confirms the administration of the oath, the affiant’s appearance and identity, and the execution of the document. It does not prove that every statement in the affidavit is true, settle a dispute, transfer property, or guarantee that an agency or court will accept the document.

What an affidavit should contain

There is no single form for every affidavit. The receiving court, prosecutor’s office, government agency, school, employer, bank, insurer, or foreign authority may prescribe its own wording and attachments.

A properly prepared general affidavit ordinarily includes:

The place where it will be sworn or notarized
The affiant’s complete name, age or legal capacity, citizenship when relevant, civil status when relevant, and address
A statement that the affiant is competent to testify about the facts
Clear, consecutively numbered factual paragraphs
An explanation of how the affiant personally knows each important fact
Exact dates, places, names, amounts, reference numbers, or document descriptions when known
Identification of each attachment, such as “Annex A”
A concluding statement describing the purpose of the affidavit
The affiant’s printed name and signature
A jurat to be completed by the notary or other officer authorized to administer the oath

Use a form supplied by the receiving authority when one exists. An affidavit for civil registration, immigration, insurance, a criminal complaint, land registration, employment, or school records may require statements that would not belong in a general affidavit.

Do not use an ordinary narrative affidavit when the required document is a judicial affidavit. The Judicial Affidavit Rule requires a question-and-answer format, specified information, identification of evidence, a jurat, and a sworn attestation from the lawyer who conducted or supervised the examination.

Jurat versus acknowledgment

An affidavit normally requires a jurat, not an acknowledgment.

In a jurat, the affiant:

Personally appears before the notary;
Is identified as required by the rules;
Signs in the notary’s presence; and
Takes an oath or affirmation regarding the affidavit.

An acknowledgment is generally used for deeds, contracts, powers of attorney, and similar instruments. The signer acknowledges that an existing signature was voluntarily placed on the document and that the document is the signer’s free act and deed.

Using the wrong notarial act can create evidentiary or filing problems. If an affidavit carries only an acknowledgment, or a deed carries only a jurat, ask the receiving authority or a lawyer whether the document must be re-executed and correctly notarized. Do not alter the notarial certificate yourself.

Personal appearance is essential

Under the 2004 Rules on Notarial Practice, a traditional notary public must not notarize a paper document when the signer is not personally present.

This means:

A relative, liaison, employee, or lawyer ordinarily cannot appear in place of the affiant.
A document should not be left with a notary for later stamping.
A notary should not certify that an affiant appeared on a date when the affiant was elsewhere.
Every affiant signing a joint affidavit must personally complete the required appearance, identification, signing, and oath.
A paper affidavit should not be signed beforehand when a jurat requires signing in the notary’s presence.

The rules contain a special procedure for a person physically unable to sign or make a mark. It involves the person’s direction, the notary’s act, and disinterested witnesses. It is not a general substitute for personal appearance. Arrange the procedure with a qualified notary before the appointment.

What identification is required?

If the affiant is not personally known to the notary, the traditional paper-notarization rule generally requires at least one current identification document issued by an official agency bearing the individual’s photograph and signature. Common examples include a valid passport, driver’s license, PRC ID, or qualifying government office ID.

The 2008 amendment on competent evidence of identity also permits identification through qualifying credible witnesses:

One credible witness who is not involved in the document, is personally known to the notary, and personally knows the affiant; or
Two credible witnesses who are not involved in the document, personally know the affiant, and present the required documentary identification to the notary.

A community tax certificate or cedula is not sufficient by itself. The Supreme Court has repeatedly explained that a cedula does not meet the photograph-and-signature safeguards of the notarial rules.

The physical, paper, and Digital National ID are valid proof of identity subject to authentication under the Philippine Identification System Act. If relying on a Digital National ID or another ID requiring electronic verification, ask the notary beforehand whether the necessary authentication can be performed.

Bring the original ID, not only a screenshot or photocopy. Check that:

It is current, if it has an expiration date;
The name matches the affidavit;
The photograph is recognizable;
The information is legible; and
Any name difference is supported by appropriate records, such as a PSA certificate or court order.

A receiving authority may impose stricter identification or supporting-document requirements even when one ID would ordinarily satisfy the notarial rule.

What the notary must check

A notary is not merely a witness who places a stamp on paper. The notary should confirm the affiant’s identity, personal appearance, understanding, willingness, and completion of the oath.

The notary must refuse or stop the act when, among other problems:

The affidavit or notarial certificate is blank or materially incomplete;
The affiant is absent;
Identity cannot be established;
The affiant appears unable to understand the document;
The signature appears coerced or involuntary;
The transaction is unlawful;
The notary knows the statement or transaction is false;
The notary has a disqualifying interest or relationship; or
The act would occur outside the notary’s authorized territorial jurisdiction.

A traditional notary is commissioned for a particular city or province and ordinarily performs notarial acts at the regular place of work stated in the commission. Limited exceptions allow acts elsewhere within the territorial jurisdiction. A commission from one city or province does not generally authorize paper notarization in another jurisdiction.

The notary is also disqualified when personally a party to the document, will receive a prohibited direct or indirect benefit, or is related to a principal within the degree prohibited by the rules.

Check the completed notarial certificate

Before leaving, review the jurat. It should accurately show:

The place of notarization;
The actual date of the notarial act;
The affiant’s correct name;
The administration of the oath or affirmation;
The competent evidence of identity, when required;
The notary’s signature and official seal;
The notary’s commission and professional details; and
The document, page, book, and series numbers corresponding to the notarial register.

The date must be the date the affiant actually appeared, signed, and took the oath. Backdating or postdating is improper.

Confirm that all pages and annexes are complete. If a material error is discovered after notarization, prepare a clean corrected document and have it properly executed and notarized again. Do not insert new paragraphs, replace an annex, change an amount, or alter a material date after the oath.

Paper, electronic, and remote notarization

Traditional notarization remains available for paper documents with handwritten signatures.

The Supreme Court’s Rules on Electronic Notarization supplement the paper rules. They permit:

In-person electronic notarization;
Remote electronic notarization by authorized videoconferencing; and
A combination of in-person and remote electronic notarization.

These modes require a commissioned Electronic Notary Public and an accredited Electronic Notarization Facility. The rules apply to qualifying electronic documents in PDF or PDF/A format and use prescribed electronic-signature, identity-verification, authentication, recording, and security procedures.

An emailed scan, an ordinary electronic signature, or a private Zoom call with a traditional notary is not enough. Use the Supreme Court’s official electronic-notarization information and FAQs to verify the notary and facility.

Paper documents with wet signatures remain under the paper rules. Notarial wills, depositions, and documents excluded by the electronic rules must follow their governing legal procedures.

Notarization does not prove the affidavit’s contents

The Supreme Court has clarified that notarization ordinarily supports the document’s due execution, authenticity, and date—not the truth of every factual assertion. The notary administers the oath but does not independently investigate and certify each statement.

In court, an affidavit may still be hearsay if offered to prove its contents without presenting the affiant for testimony and cross-examination, unless an applicable rule or exception permits its admission. The 2019 Amendments to the Rules on Evidence and the applicable procedural rules control.

A notarized affidavit also cannot, by itself:

Transfer ownership of land or a vehicle;
Replace a required deed, contract, will, or special power of attorney;
Correct a PSA civil-registry entry;
Cancel a lost title, check, ID, or negotiable instrument;
Prove that a debt has been paid;
Establish citizenship, filiation, marriage, or ownership conclusively;
Waive another person’s rights; or
Bind a person who did not execute or authorize it.

The legal result depends on the governing law, the wording of the affidavit, supporting documents, and the proceeding in which it is used.

False statements and perjury

An affiant should review every sentence before taking the oath. Do not include assumptions, rumors, invented dates, or statements supplied by another person unless they are clearly attributed and legally relevant.

Under Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, perjury may be committed when a person willfully and deliberately makes a false statement about a material matter under oath before an authorized officer, where the affidavit is required by law or made for a legal purpose.

The prescribed penalty is prision mayor in its minimum period—six years and one day to eight years. Special consequences apply when the offender is a public officer or employee. Not every mistake is perjury: the prosecution must prove the statutory elements, including a deliberate falsehood on a material matter.

If something is uncertain, say so accurately. Phrases such as “to the best of my personal knowledge,” “I do not recall the exact date,” or “according to the attached official record” may be appropriate when truthful, but they should not be used to hide a knowingly false statement.

Practical preparation checklist

Before going to the notary:

Obtain the latest form or checklist from the receiving authority.
Confirm the filing deadline and whether the affidavit must have been executed within a stated period.
Draft only facts relevant to the purpose.
Separate personal knowledge from information learned from records or other people.
Verify all names, dates, addresses, amounts, account numbers, and property descriptions.
Label and attach every referenced annex.
Remove unfilled blanks or mark inapplicable spaces appropriately.
Bring the complete document unsigned.
Bring the original qualifying ID and supporting records.
Arrange an interpreter or accessibility accommodation in advance when needed.
Confirm that the notary has a current commission for the place of notarization.
Ask the fee before proceeding and request a receipt when appropriate.

At the appointment:

Read the final document personally.
Correct errors before signing.
Present the original ID.
Answer the notary’s identity and capacity questions truthfully.
Sign only when instructed.
Take the oath or affirmation.
Watch the notary complete, sign, and seal the jurat.
Check the date, venue, names, ID details, and register information.

After notarization:

Scan or photograph the complete affidavit and annexes.
Preserve the original ID used and proof that it was current on the notarization date.
Keep the receipt and the notary’s office details.
Record when, where, how, and to whom the affidavit was filed.
Preserve email acknowledgments, registry receipts, filing stamps, or electronic confirmations.
Do not alter the document.
File it within the deadline imposed by the receiving authority.

Deadlines, “validity,” and recent-affidavit requirements

There is no universal rule that every notarized affidavit expires after three or six months. Notarization itself does not create a standard expiration date.

However, the receiving authority may require:

An affidavit executed within a specified number of days or months;
A particular version of an agency form;
Submission by a statutory or procedural deadline;
Recently issued supporting documents; or
Re-execution when circumstances have changed.

An old affidavit may also become factually unreliable even if it has no formal expiration date. If the affidavit states present residence, employment, civil status, financial capacity, custody, loss, or another changing fact, confirm that it remains accurate when submitted.

Affidavits executed abroad

A person abroad generally has two possible routes, subject to the receiving authority’s requirements:

Personally appear before a Philippine embassy or consulate that offers notarial services and execute the affidavit before a consular officer; or
Use a qualified local notary in the foreign country and obtain the required Apostille or legalization.

For a document from a country covered by the Apostille Convention, an Apostille issued by that country’s competent authority generally replaces Philippine consular authentication. Different legalization steps may apply in a non-Apostille country.

Check the relevant Philippine embassy or consulate because appointment systems, forms, copies, identification, fees, and mailing procedures differ by post. The DFA’s Apostille FAQs explain the distinction between Philippine documents for use abroad and foreign documents for use in the Philippines.

For a Philippine notarized private document intended for use abroad, the receiving country may require a Certificate of Authority for a Notarial Act from the supervising Regional Trial Court before the DFA Apostille. Verify the current DFA documentary requirements and the foreign recipient’s instructions before spending money.

Common mistakes to avoid

Signing a jurat before meeting the notary
Sending another person to obtain the seal
Using only a cedula as identification
Presenting an expired, damaged, or mismatched ID
Leaving material blanks in the affidavit
Copying a generic online form without checking the agency’s requirements
Stating conclusions instead of specific facts
Including facts the affiant did not personally observe without identifying the source
Omitting or changing annexes after notarization
Using an acknowledgment where a jurat is required
Accepting a backdated notarial certificate
Using a notary outside the notary’s authorized jurisdiction
Treating an informal video call as remote notarization
Assuming notarization makes a false or unlawful document valid
Assuming a notarized affidavit is conclusive proof in court
Missing the filing deadline while focusing only on notarization

When legal help is urgent

Consult a Philippine lawyer promptly when:

A court, prosecutor, regulator, or government agency has imposed a filing deadline;
The affidavit is a complaint-affidavit, counter-affidavit, judicial affidavit, verification, or certification against forum shopping;
You are being asked to admit criminal conduct, liability, debt, fraud, abandonment, or ownership;
The document concerns land, inheritance, custody, marriage, immigration, employment termination, or a large financial transaction;
Someone wants you to sign a blank, incomplete, backdated, or inaccurate affidavit;
A signature or notarization appears forged;
The notary recorded an appearance that never occurred;
The affiant is a minor, has impaired capacity, cannot read the document, or is being pressured;
The affidavit will be used abroad; or
A defective affidavit has already been filed or relied upon.

If cost is a barrier, inquire with the Public Attorney’s Office, an Integrated Bar of the Philippines legal-aid office, a law-school legal-aid clinic, or another qualified legal-aid provider. Eligibility and available services vary.

Frequently asked questions

Can someone else have my affidavit notarized for me?

Generally, no. The affiant must personally appear, establish identity, sign in the required manner, and take the oath. A representative cannot truthfully complete those acts for the affiant.

Can I sign the affidavit before going to the notary?

For a jurat, the affidavit must be signed in the notary’s presence. Bring it unsigned unless the notary or governing procedure has given lawful instructions for an authorized electronic process.

Is one government ID enough?

Under the traditional paper rule, at least one current official identification document satisfying the rule may be sufficient. A notary may reasonably request additional proof where identity, name consistency, or authenticity requires clarification. A receiving agency may also impose separate requirements.

Is a cedula a valid ID for notarization?

Not by itself. Supreme Court rulings explain that a community tax certificate lacks the photograph-and-signature safeguards required by the notarial rules.

Can an affidavit be notarized online?

A qualifying electronic affidavit may be notarized remotely through a commissioned Electronic Notary Public using an accredited Electronic Notarization Facility. An ordinary video call, emailed scan, or pasted electronic seal is not a compliant substitute.

Does a notarized affidavit expire?

There is no universal expiration period. The receiving authority may require a recently executed affidavit, and an affidavit should not be used after its factual statements have become outdated.

Does notarization mean the government or court accepts my claim as true?

No. Notarization confirms the notarial acts performed. The contents may still be disputed, investigated, excluded, or disproved.

Can a defective notarization be corrected by changing the jurat?

Do not alter it yourself. Depending on the defect, the affidavit may need to be re-executed and notarized. A defective notarization may cause the document to lose its public character and evidentiary presumptions, although it does not automatically determine every underlying legal issue.
