Quick answer

An affidavit is a written statement that the affiant swears or affirms is true before a person authorized to administer an oath. For a paper affidavit in the Philippines, the usual notarial act is a jurat: the affiant must be properly identified, sign the complete document in the notary public’s presence, and take an oath or affirmation.

Do not sign a paper affidavit beforehand unless the notary specifically instructs you under an applicable procedure. Every affiant—including every signer of a joint affidavit—must personally complete the required appearance, identification, signing, and oath. A representative cannot ordinarily swear to facts for an absent affiant.

Electronic notarization is also legally available, but only through a commissioned Electronic Notary Public and a Supreme Court-accredited Electronic Notarization Facility. An ordinary video call, emailed scan, electronic signature, or online “notary” service does not by itself create a valid Philippine notarization.

What an affidavit must contain

There is no single form for every affidavit. The governing law, court, agency, bank, school, employer, or transaction may prescribe its own wording and attachments. A properly prepared general affidavit ordinarily contains:

The correct title and, for a court filing, the court caption and case number.
The affiant’s complete legal name and relevant personal circumstances.
Clear, numbered statements of fact, preferably arranged chronologically.
Facts within the affiant’s personal knowledge. If information came from records or another source, the affidavit should identify that basis instead of presenting it as firsthand knowledge.
Exact names, dates, locations, amounts, document numbers, and other material details that can be verified.
References to supporting documents, photographs, messages, receipts, or other exhibits, with the exhibits properly labelled and attached.
The affiant’s signature over the printed name.
A complete jurat stating when and where the oath or affirmation was administered.
The notary’s signature, seal, commission information, and notarial register details.

The “venue” appearing near the beginning or jurat is the city or province where the oath is actually administered—not necessarily the affiant’s residence.

Do not use a generic form where a special affidavit is required. Affidavits involving loss, adverse claims, estates, land, corporate authority, immigration, civil registry corrections, criminal complaints, tax matters, or government benefits may require particular allegations, witnesses, documents, or filing steps.

Jurat versus acknowledgment

These notarial acts serve different purposes:

Notarial act	What the signer does
Jurat	Appears before the notary, signs in the notary’s presence, and swears or affirms that the affidavit’s contents are true.
Acknowledgment	Appears before the notary and declares that an existing signature was voluntarily made for the purposes stated in the document.
Electronic jurat	Electronically appears before a commissioned Electronic Notary Public through an accredited facility, signs electronically in the ENP’s presence, and takes the oath or affirmation.

Because an affidavit is a sworn statement, it ordinarily requires a jurat. A mere acknowledgment may not give the document the sworn character required by a court or agency.

The 2004 Rules on Notarial Practice define a jurat as requiring appearance, identification, signing in the notary’s presence, and an oath or affirmation.

What to bring to a paper notarization

Bring:

The complete but unsigned affidavit.
All pages and referenced attachments or exhibits.
At least one current government-issued identification document bearing your photograph and signature.
Any document showing your authority to sign in a representative capacity, if applicable.
The exact filing or submission instructions from the receiving court or office.
Payment for the disclosed notarial fee and any separate drafting or legal-service fee.

Examples listed in the amended identity rule include passports, driver’s licences, PRC IDs, SSS cards, GSIS e-cards, senior citizen cards, government-office IDs, and other current official credentials bearing the required identifying features. The Supreme Court’s 2008 amendment on competent evidence of identity contains the governing standard and examples.

A Community Tax Certificate or cedula is not competent evidence of identity for notarization. The Supreme Court has repeatedly confirmed this, including in Kiener v. Amores.

The National ID or PhilID is separately recognized by the Philippine Identification System Act as sufficient proof of identity, subject to proper authentication. Bring the original or QR-verifiable credential. Carrying a backup current signature-bearing ID can prevent delay if authentication equipment or connectivity is unavailable.

If the affiant has no standard ID

The rules provide a limited credible-witness alternative:

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, personally know the affiant, and present the required documentary identification.

Arrange this with the notary beforehand. A friend, relative, beneficiary, buyer, seller, or other person involved in the transaction may be disqualified from serving as the identifying witness.

What must happen before the notary

For an ordinary paper jurat, the notary should:

Examine the complete affidavit and notarial certificate.
Confirm the affiant’s identity.
Ensure that the affiant appears voluntarily and understands the document and its consequences.
Watch the affiant sign or place the permitted mark.
Administer the oath or affirmation.
Sign and seal the notarial certificate.
Record the act in the notarial register and require the appropriate signature, thumbmark, or mark in that register.
Supply the document, page, book, and series information corresponding to the register entry.

A notary should refuse an incomplete or blank document, an unlawful transaction, a document the signer does not understand, or a transaction that does not appear to be the signer’s free act. A notary is also disqualified when personally interested in the transaction or related to a principal within the degree prohibited by the rules.

Notarial work cannot be delegated to a secretary, paralegal, messenger, or office employee. The commissioned notary must personally perform the notarial act.

Physical disability, illness, language, or inability to sign

Tell the notary in advance if the affiant:

Cannot write or make an ordinary signature;
Has a visual, hearing, speech, mobility, or cognitive impairment;
Is confined in a hospital, care facility, or detention facility;
Needs an interpreter or does not understand the affidavit’s language; or
Requires assistance reading or reviewing the document.

The notarial rules contain procedures for signatures by mark and, in narrowly defined circumstances, for a notary to sign at the individual’s direction in the presence of qualified witnesses. These safeguards must be arranged correctly; another person should not simply sign the affiant’s name.

A notary ordinarily acts within the territorial jurisdiction and regular place of business covered by the commission, subject to recognized exceptions. For a home, hospital, or institutional notarization, confirm in advance that the proposed place and procedure are lawful.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement rather than replace traditional notarization.

Electronic notarization may be conducted in person, remotely by videoconference, or through a combination of those modes. It applies to electronic documents in PDF or PDF/A format and must use:

A commissioned Electronic Notary Public;
A Supreme Court-accredited Electronic Notarization Facility;
The facility’s identity-verification, geolocation, electronic-signature, and security procedures; and
An electronic notarial seal and certificate.

For an electronic affidavit requiring a jurat, do not electronically sign before the notarial session. The electronic signature must be placed in the ENP’s presence. Each principal and witness must use an individually verified account.

An ENP may serve a principal located anywhere in the Philippines. A principal abroad may use remote electronic notarization only under the special conditions in the rules, including being within an authorized Philippine foreign-service post and having an officer confirm the principal’s presence. Availability may also depend on the host country’s law and the foreign post’s facilities.

Notarial wills and depositions are excluded from electronic notarization. Consult the Supreme Court’s current Electronic Notary Services FAQs and official lists before paying or uploading personal documents.

Deadlines, validity, and fees

There is no universal deadline or expiration period for every affidavit. The controlling period comes from the law, court order, subpoena, agency procedure, contract, or receiving office. Some recipients also require an affidavit executed within a specified number of days even though notarization itself has no blanket expiration date.

A particularly important exception is a judicial affidavit. Under the Judicial Affidavit Rule, A.M. No. 12-8-8-SC, parties generally file and serve judicial affidavits and exhibits no later than five days before the applicable pre-trial, preliminary conference, or scheduled hearing. Criminal proceedings have additional prosecution and defence periods. Late submission may be treated as waived, subject only to the rule’s limited relief.

Notarial and drafting charges are not necessarily the same. Ask for the applicable fee before the appointment and request an official receipt. Documentary stamp, apostille, courier, translation, or filing charges may apply to particular uses, but they are not automatically required for every affidavit.

Affidavits for use abroad

Notarization and international authentication are separate steps.

For a Philippine affidavit to be used abroad, the destination country or receiving institution may require certification of the notarial act followed by a DFA Apostille or authentication. Follow the current DFA Authentication Division documentary requirements and confirm whether the destination accepts Apostilles.

For an affidavit executed abroad for use in the Philippines, the usual options are:

Execution before a Philippine embassy or consulate; or
Notarization under the foreign country’s law followed by an Apostille or the required authentication/legalization process.

The correct route depends on the country, the document, and the Philippine receiving office. Obtain written requirements before execution because a document validly notarized abroad can still be rejected for using the wrong form, certification chain, or language.

What notarization does—and does not do

Proper notarization gives a private document the evidentiary character of a public document as to its authenticity and due execution. It generally removes the initial need to prove that the signature and execution are genuine. The Supreme Court explains this effect in decisions such as Kiener v. Amores.

Notarization does not:

Prove that every factual statement is true;
Transfer ownership or establish legal authority that the affiant does not have;
Cure fraud, forgery, coercion, illegality, lack of capacity, or a defective underlying transaction;
Replace required supporting records;
Guarantee acceptance by every court, agency, foreign authority, or private institution; or
Prevent another person from contesting the affidavit and presenting contrary evidence.

An improperly notarized affidavit may lose its sworn or public-document character. Whether it can be corrected, accepted as a private document, or must be replaced depends on the governing proceeding and the nature of the defect.

False statements and alterations

Never swear to a fact merely because another person drafted it or told you it was correct. Read every page and attachment before taking the oath.

Knowingly making a materially false statement in an affidavit can result in prosecution for perjury when the statutory elements are present. Republic Act No. 11594 increased the penalties under Article 183 of the Revised Penal Code. Forgery, falsification, fraud, obstruction, or other offences may also apply depending on the conduct.

Do not backdate an affidavit or ask a notary to make it appear that an absent person appeared. Do not erase, overwrite, replace pages, use correction fluid, or add material text after notarization. If a material error is discovered, consult the receiving office or lawyer; executing a corrected affidavit is usually safer than altering the notarized original.

Practical checklist

Before notarization:

Obtain the receiving office’s latest form and requirements.
Confirm the filing deadline and required number of originals or copies.
Check all names and numbers against official records.
Arrange facts chronologically and remove speculation.
Label and attach every referenced exhibit.
Remove material blanks, but leave the jurat and notarial details for the notary.
Prepare acceptable identification and any proof of signing authority.
Do not sign a jurat in advance.

After notarization:

Check that the actual place and date are correct.
Confirm that the jurat, notary’s signature, seal, commission details, and register information are complete.
Scan the entire final document, including exhibits and the notarial page.
Preserve the original securely.
Keep the receipt, submission instructions, and proof of timely filing or delivery.
For electronic notarization, retain the final electronically notarized file, validation information, electronic receipt, and any requested audiovisual recording.
Protect copies containing ID numbers, addresses, signatures, or other sensitive personal information.

Common mistakes

Signing the affidavit before an ordinary paper-jurat appointment.
Sending someone else to “have it notarized.”
Using only a cedula as identification.
Allowing a secretary to stamp or sign for the notary.
Leaving material blanks or omitting referenced exhibits.
Using an acknowledgment where a jurat is required.
Using a generic internet template despite an agency-specific form.
Using inconsistent names, civil status, addresses, dates, or identification numbers.
Treating assumptions, rumours, or another person’s account as personal knowledge.
Assuming notarization proves ownership or the truth of disputed facts.
Using an expired, disqualified, or territorially unauthorized notary.
Paying an unverified “online notary” operating outside an accredited Supreme Court facility.
Missing the filing deadline after completing the notarization.
Altering, substituting, or photocopying pages after the document has been notarized.

When legal help is urgent

Consult a Philippine lawyer promptly when:

A court, prosecutor, police officer, regulator, or government agency has set a deadline.
You have received a subpoena, complaint, demand letter, or order to submit a counter-affidavit.
The affidavit concerns criminal conduct, domestic violence, child safety, detention, or possible perjury.
Property, inheritance, corporate control, immigration status, employment termination, or a substantial amount of money is involved.
Someone disputes the signature, identity, authority, capacity, or voluntariness of an affiant.
The affidavit was notarized without personal appearance, backdated, forged, or altered.
You are being pressured to sign facts you cannot verify.
An overseas authority requires an Apostille, legalization, translation, or unfamiliar certification.
A filing has already been rejected or its deadline has passed.

Persons who qualify for free legal assistance may inquire with the Public Attorney’s Office or an appropriate legal-aid provider.

Frequently asked questions

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

Ordinarily, no. A paper affidavit requiring a jurat must be signed in the notary’s presence. Bring it unsigned unless a different authorized procedure clearly applies.

Must all signers of a joint affidavit appear?

Yes. Every affiant must be identified, sign as required, and personally take the oath or affirmation. One affiant cannot complete the jurat for absent co-affiants.

Is a cedula enough?

No. A Community Tax Certificate is no longer competent evidence of identity for notarization.

Does a notarized affidavit prove that its contents are true?

No. It proves the formal execution and administration of the oath when properly performed. The factual statements may still be investigated, contradicted, or challenged.

Can I notarize through Zoom or a messaging app?

Not merely by using those applications. Electronic notarization must be conducted by a commissioned ENP through a Supreme Court-accredited facility. Special remote-paper procedures cannot be assumed to apply to an ordinary transaction.

Does an affidavit expire?

There is no general expiration rule for all affidavits. The receiving institution may impose a recency requirement, and the underlying claim or filing may have a statutory deadline.

Can an error be corrected after notarization?

Do not alter the notarized document yourself. Ask the receiving office or a lawyer whether a newly executed corrected affidavit, supplemental affidavit, or other formal correction is required.

Can a notary refuse to notarize?

Yes. A notary should refuse when identity, voluntariness, comprehension, completeness, legality, authority, or another required safeguard is doubtful.
