Quick answer

An affidavit is a written statement of facts that the maker—called the affiant—confirms under oath or solemn affirmation. For an ordinary paper affidavit in the Philippines, the affiant must generally:

State facts truthfully, clearly, and preferably from personal knowledge.
Use the form required by the court, agency, school, bank, employer, or other receiving office.
Bring the complete, unsigned affidavit and acceptable proof of identity to a duly commissioned notary public.
Personally appear before the notary.
Sign in the notary’s presence and take an oath or affirmation.
Check that the notary completed the jurat, signed and sealed the document, and entered the act in the notarial register.

Notarization does not prove that every statement in an affidavit is true. It formally records that the identified affiant personally appeared, signed, and swore or affirmed before an authorized officer. Requirements may be stricter for court filings, government transactions, documents executed abroad, electronic notarization, or affidavits governed by a specific law or agency rule.

What makes a document an affidavit?

A document is not an affidavit merely because it is titled “Affidavit” or contains a signature. Ordinarily, it must contain:

The affiant’s full name and relevant personal details;
Numbered or clearly separated statements of fact;
A statement showing why the affiant knows those facts;
The purpose for which the affidavit is being executed;
The affiant’s signature; and
A properly completed jurat showing that the affiant subscribed and swore to—or solemnly affirmed—the statement before an authorized officer.

The affidavit should identify dates, places, people, documents, amounts, and events as precisely as the affiant can truthfully do. If a fact came from a record or another person rather than the affiant’s direct knowledge, the affidavit should say so instead of presenting it as personally witnessed.

Common examples include affidavits of loss, discrepancy, residency, support, consent, desistance, adverse claim, two disinterested persons, and complaint. Each has a different legal purpose. A generic template may omit facts or certifications required for the particular transaction.

Jurat versus acknowledgment

These notarial acts are not interchangeable.

Jurat

A jurat is normally used for an affidavit. Under the notarial rules, the affiant personally appears before the notary, signs the document in the notary’s presence, and takes an oath or affirmation that the statements are true.

A typical jurat begins with wording such as “Subscribed and sworn to before me,” but wording alone is not enough. The personal appearance, identification, signing, and administration of the oath must actually occur.

Acknowledgment

In an acknowledgment, the signer personally appears, presents a complete instrument, and declares that the signature was voluntarily affixed and that the instrument is the signer’s free and voluntary act. If signing for a corporation, partnership, principal, or another person, the signer also represents that they have authority to act in that capacity.

Acknowledgments are commonly used for deeds, contracts, and powers of attorney. They do not ordinarily replace the oath required for an affidavit.

If the receiving office prescribes a jurat, acknowledgment, verification, or combined certification, do not alter it without confirming the applicable rule.

Personal appearance is the general rule

For traditional notarization, the affiant must be physically present before the notary when the notarial act is performed. Sending a signed affidavit through a relative, messenger, lawyer’s assistant, or delivery service is not a valid substitute.

The Supreme Court has repeatedly treated personal appearance as an essential safeguard against forgery and impersonation. A notary should not notarize an affidavit based only on a telephone call, text message, specimen signature, photocopied identification card, or another person’s assurance.

Do not agree to:

Sign a blank or incomplete affidavit;
Leave the document for later notarization without appearing;
Have someone else swear to the affidavit for you;
Backdate the jurat;
Use a notarial certificate or seal supplied by a secretary without the notary personally performing the act; or
State that you appeared at a place or date where no appearance occurred.

A notarization obtained without the required appearance may be challenged, and the notary may face administrative discipline.

Identification requirements

The notary must either personally know the affiant or identify the affiant through competent evidence of identity.

The usual and safest proof is at least one current identification document issued by an official agency bearing the affiant’s photograph and signature. Bring the original, not merely a screenshot or photocopy. The name and signature should correspond with the affidavit; explain material differences before signing.

Examples may include a current passport, driver’s license, or another government-issued photo-and-signature identification document. Acceptance depends on whether the document meets the notarial rule and allows the notary to be satisfied as to identity. A Community Tax Certificate or cedula by itself is not competent evidence of identity under the present rule.

Where the rules allow identification through credible witnesses, the conditions are specific: the witnesses must personally know the affiant, be personally known to the notary, be unaffected by the document, and swear or affirm to the affiant’s identity. This is not an automatic workaround for having no valid ID. Ask the notary in advance.

The receiving institution may independently demand particular IDs or supporting records even if the notary accepts the proof of identity.

The document must be complete

A notary should not notarize a blank or incomplete instrument. Before appearing, check that:

All pages are present and in the correct order;
Names, addresses, dates, amounts, and identification details are accurate;
Empty spaces that could later be filled in are removed or properly crossed out;
Annexes mentioned in the affidavit are attached and correctly labeled;
Alterations are explained or countersigned where appropriate;
The venue states the correct city, municipality, or province;
The correct person is named as affiant; and
The jurat, rather than an inappropriate acknowledgment, is provided.

Do not ask the notary to certify facts the notary cannot legally certify. A notary verifies identity, appearance, voluntariness, and the required oath or affirmation; the notary is not a witness to the underlying event merely because the affidavit is notarized.

Step-by-step checklist

1. Ask the receiving office for its exact requirements

Confirm:

Whether it has a prescribed form;
Whether notarization is required;
Whether original copies, duplicate originals, witnesses, photographs, fingerprints, annexes, or documentary stamps are required;
The filing method and office;
The deadline and whether it is counted in calendar or working days; and
Whether electronic, consular, foreign, or remote notarization will be accepted.

There is no single filing deadline for all affidavits. The deadline comes from the transaction, statute, court rule, order, contract, or agency procedure involved.

2. Prepare a fact-specific draft

Use short, numbered paragraphs. Include only relevant facts that you can support. If the affidavit concerns a loss, for example, identify the item or document, when and where it was last possessed, when the loss was discovered, and the reasonable efforts made to locate it.

Do not copy allegations from an unrelated template merely because they sound formal.

3. Gather supporting evidence

Depending on the affidavit, preserve:

Original IDs and clear copies;
Receipts, certificates, contracts, and official records;
Emails, messages, call logs, and delivery records;
Photographs or video;
Police, barangay, medical, or incident reports;
Names and contact details of witnesses;
File metadata and unedited electronic copies; and
Any notice, summons, order, denial, or deadline from the receiving office.

Keep originals secure and submit copies unless an original is expressly required.

4. Review before taking the oath

Read every paragraph. Ask for corrections if the draft does not accurately reflect what you said. Do not sign a statement you do not understand. Request an explanation or translation if needed.

5. Appear before a duly commissioned notary

Bring the complete affidavit, original identification, supporting records the notary requests, and all required signatories and witnesses. The notary must have authority to act in the territorial jurisdiction where the notarization occurs.

Sign only as instructed. For a jurat, the signing and oath or affirmation must occur before the notary.

6. Inspect the completed notarization

Before leaving, check that the notarial certificate contains the date and place, the notary’s signature and seal, commission details, and the document’s notarial-register particulars. Confirm that the affiant’s name and identification details are correct.

Obtain the required number of originals or certified copies and keep a complete scan.

7. File with the proper office on time

Notarization and filing are separate acts. Having an affidavit notarized does not automatically submit it to a court, police station, prosecutor, government agency, insurer, bank, or employer.

Request proof of filing or receipt and preserve the reference number, stamped copy, email confirmation, or courier tracking record.

Electronic notarization

The Supreme Court has issued separate Rules on Electronic Notarization, which contemplate accredited Electronic Notaries Public and authorized electronic-notarization facilities. Electronic notarization is not the same as emailing a scanned signature to an ordinary notary or appearing through an informal video call.

Because implementation depends on Supreme Court accreditation, authorized systems, the notary’s commission, and the type of document, confirm all of the following before relying on it:

The person is currently commissioned as an Electronic Notary Public;
The transaction is performed through an authorized facility;
The required identity verification and synchronous interaction are completed;
The electronic signatures and notarial certificate comply with the rules; and
The receiving court, agency, registry, or private institution accepts the resulting electronic document for the intended purpose.

Traditional paper notarization under the amended 2004 rules remains available for paper documents with wet signatures. Never treat a pasted image of a signature or seal as valid electronic notarization.

Affidavits executed outside the Philippines

A person abroad may generally use an authorized Philippine embassy or consulate where consular notarial service is available. Personal appearance, a valid passport or other specified identification, appointments, copies, fees, and local requirements may apply.

Another possibility is execution before a foreign notary followed by an Apostille or other authentication required for use in the Philippines. The proper route depends on:

Whether the country is a party to the Apostille Convention;
The law and competent authority of that country;
The nature of the affidavit; and
The requirements of the Philippine receiving office.

An Apostille authenticates the origin of a public document; it does not establish that the affidavit’s factual statements are true. Check the relevant Philippine embassy or consulate and the receiving office before execution, especially when a deadline is approaching.

Legal effect and limits of notarization

Proper notarization can convert a private document into a public document for evidentiary purposes and gives rise to a presumption of regularity in its execution. That presumption is rebuttable.

Notarization does not:

Cure false, unlawful, vague, or incomplete statements;
Prove the truth of every allegation;
Give the affiant personal knowledge they do not have;
Make an invalid transaction valid;
Replace required testimony, cross-examination, authentication, or formal offer of evidence;
Waive another party’s defenses; or
Guarantee that a court or agency will accept the affidavit.

The Supreme Court has explained that even a notarized document is not a guarantee of the validity of its contents. In litigation, an affidavit may still face hearsay, admissibility, credibility, authentication, and evidentiary-weight issues. A witness may have to testify and be cross-examined unless a governing rule provides otherwise.

False statements and perjury

An oath is not a formality. Knowingly making an untruthful statement under oath about a material matter, before a person authorized to administer the oath, in a case in which the law requires it, may constitute perjury under Article 183 of the Revised Penal Code as amended by Republic Act No. 11594.

The present statutory penalty is serious: prisión mayor in its minimum period. Additional consequences apply to a public officer or employee, including the statutory fine and disqualification specified in the law.

Not every mistake automatically amounts to perjury. Criminal liability depends on the statutory elements, including knowledge, materiality, authority to administer the oath, and the circumstances in which the law required the sworn statement. Correct a genuine error promptly and obtain legal advice before submitting a replacement, retraction, or explanation.

Common mistakes

Using an affidavit when the receiving office requires a different instrument;
Signing before meeting the notary;
Appearing without an original acceptable ID;
Relying only on a cedula;
Leaving material blanks or unattached annexes;
Describing assumptions or second-hand information as personal knowledge;
Omitting facts that materially change the meaning of a statement;
Using an acknowledgment when a jurat is required;
Assuming notarization is equivalent to filing;
Missing a separate court or agency deadline;
Altering a document after notarization;
Submitting only the notarized page without the complete affidavit;
Paying a fixer or allowing office staff to perform the notarial act in the notary’s absence; or
Assuming that any video call or digital signature qualifies as electronic notarization.

When legal help is urgent

Consult a Philippine lawyer promptly if:

You have received a subpoena, summons, warrant, demand, dismissal notice, or court order;
A filing period, appeal period, prescriptive period, or government deadline is near;
The affidavit may admit a crime, debt, breach, fraud, violence, abuse, or regulatory violation;
Someone is pressuring you to sign facts you dispute or do not understand;
Your signature, identity, seal, or notarization appears to have been forged;
A document was notarized without your appearance;
You need to withdraw or correct a material sworn statement;
The affidavit concerns land, inheritance, corporate authority, immigration, child custody, domestic violence, or a substantial financial interest;
A foreign-executed document must be used immediately in the Philippines; or
The proper form, signatory, authority, or filing office is uncertain.

If there is immediate danger, contact emergency services or the appropriate law-enforcement or protective agency rather than waiting to prepare an affidavit.

Frequently asked questions

Can I sign the affidavit before going to the notary?

For a jurat, the affidavit should be signed in the notary’s presence while the oath or affirmation is administered. Bring an unsigned copy unless the notary or the governing procedure lawfully instructs otherwise.

Is one government ID enough?

One current official-agency identification document bearing a photograph and signature may satisfy the notarial rule, but the notary must still be satisfied as to identity. The notary or receiving office may reasonably require additional proof, particularly where names or signatures differ.

Is a barangay ID or Community Tax Certificate enough?

It depends on whether the particular ID meets the rule’s requirements. A Community Tax Certificate or cedula alone is not competent evidence of identity under the current notarial rule.

Can a relative have my affidavit notarized for me?

No. A representative may deliver or file a completed document where allowed, but cannot replace the affiant’s required appearance, signature, and oath.

Can the notary prepare the affidavit?

A lawyer may draft a document when professionally engaged to do so, but notarization is a separate official act. The affiant remains responsible for reviewing and truthfully confirming every statement. The notary must also observe rules on disqualifying interests and prohibited acts.

Does an affidavit expire?

There is no universal expiration period for all affidavits. An affidavit may become stale because the receiving office imposes a recency requirement, the facts change, or a filing deadline passes. Ask the receiving office how recently the affidavit must have been executed.

Does notarization make my affidavit conclusive evidence?

No. It supports the regularity of execution but does not conclusively establish the truth of the contents. The statement may still be contradicted, excluded, or given little weight depending on the applicable evidentiary rules and the surrounding facts.

Can I correct a notarized affidavit by writing on it?

Do not make material handwritten changes after notarization. Prepare a corrected or supplemental affidavit and have it properly executed, then explain or withdraw the earlier version through the procedure required by the receiving office.

Are notarial fees fixed nationwide?

Do not assume a single nationwide private-notary fee for every document. Charges may depend on the service and applicable local or professional rules. Government and consular offices publish separate schedules. Ask for the amount in advance and request a receipt when appropriate.
