Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. Signing a document and adding a notarial stamp is not enough. For a traditional paper affidavit in the Philippines, the affiant must generally:

Complete the affidavit without material blanks;
Personally appear before a duly commissioned notary public or another officer authorized to administer oaths;
Prove identity through the notary’s personal knowledge or competent evidence of identity;
Sign the affidavit in the notary’s presence; and
Take an oath or affirmation that its contents are true.

The proper notarial certificate for an affidavit is ordinarily a jurat, usually beginning with “Subscribed and sworn to before me.” An acknowledgment—which confirms that a signature was voluntarily affixed to a deed or instrument—is not an interchangeable substitute.

For paper notarization, ordinary video calls, sending a pre-signed affidavit through a messenger, or allowing a secretary to stamp it do not satisfy the personal-appearance rule. Electronic and remote notarization are now possible, but only through a commissioned Electronic Notary Public and a Supreme Court-accredited Electronic Notarization Facility—not through an informal Zoom, Messenger, or video call.

What an affidavit should contain

There is no single form for every Philippine affidavit. The receiving court, prosecutor, government office, bank, school, employer, or private institution may prescribe its own form and supporting documents. A properly prepared general affidavit will usually contain:

A title identifying the kind of affidavit;
The place or venue of execution;
The affiant’s complete name and relevant personal details;
A statement that the affiant has been duly sworn;
Clear, numbered factual allegations;
The source of the affiant’s knowledge;
Identification of supporting documents or annexes;
The reason the affidavit is being executed, when relevant;
The affiant’s signature over the printed name; and
A completed jurat signed and sealed by the notary or authorized officer.

Use the name appearing on the identification document unless the purpose of the affidavit is to explain a discrepancy. If different names, dates, addresses, or spellings appear in the relevant records, identify each discrepancy accurately and attach the records required by the receiving office.

State only facts the affiant can truthfully support. If information came from a record or another person, identify that source instead of presenting it as a personally witnessed fact. Notarization does not turn hearsay, speculation, or an unsupported conclusion into reliable evidence.

Jurat versus acknowledgment

Notarial act	What it establishes	Usual application
Jurat	The affiant appeared, was identified, signed in the notary’s presence, and took an oath or affirmation about the document	Affidavits, sworn statements, and verified pleadings
Acknowledgment	The signer appeared, was identified, and declared that an already complete instrument was voluntarily executed as the signer’s free act or deed	Deeds, contracts, powers of attorney, and similar instruments
Signature witnessing	The signer was identified and signed in the notary’s presence	Documents requiring witnessed signatures but not necessarily an oath

Under the 2004 Rules on Notarial Practice, a jurat requires the affiant to sign in the notary’s presence and take an oath or affirmation. The Supreme Court has repeatedly treated a jurat as distinct from an acknowledgment.

A certificate labeled “ACKNOWLEDGMENT” but worded as “subscribed and sworn” may create uncertainty or cause rejection. The certificate should accurately describe the notarial act that actually occurred.

Identification requirements

If the notary does not personally know the affiant, the general rule requires at least one current identification document issued by an official agency and bearing the person’s photograph and signature. Examples may include a qualifying passport, driver’s license, PRC ID, SSS or GSIS card, senior-citizen ID, seaman’s book, or alien certificate of registration.

The Supreme Court’s 2008 amendment says at least one qualifying current identification document. A receiving institution or notary may nevertheless request additional identification where necessary to resolve a discrepancy, authenticate a newer ID format, or comply with a separate regulation.

A community tax certificate or cedula alone is not competent evidence of identity because it does not meet the photograph-and-signature requirement. The Supreme Court has expressly rejected reliance on a cedula alone in notarial practice.

When no qualifying ID is available, the rules permit identification through credible witnesses:

One credible witness who is not involved in the transaction, is personally known to the notary, and personally knows the affiant; or
Two credible witnesses who are not involved in the transaction, each personally knows the affiant, and each presents qualifying documentary identification.

This is not satisfied by bringing any two acquaintances. The credible-witness conditions must be met, and the notary may decline if identity cannot be established reliably.

The paper-notarization process

1. Obtain the correct form first

Ask the receiving office for its latest form, checklist, number of originals, acceptable language, required attachments, and filing deadline. Requirements for an affidavit of loss, discrepancy, support, consent, heirship, delayed registration, complaint, or employment are not necessarily the same.

Do this before notarization. Adding required facts or attachments afterward can make the notarized copy inconsistent or incomplete.

2. Prepare a complete but unsigned affidavit

Check every name, date, amount, document number, address, and attachment. Remove unused alternatives and fill or strike out material blank spaces.

For a paper jurat, bring the final affidavit unsigned. The affiant must sign in the notary’s presence. If a draft was signed prematurely, disclose that fact and follow the notary’s instructions rather than concealing it or presenting it as newly signed.

3. Bring the originals needed for verification

Bring:

The final affidavit and the number of copies required;
A current qualifying identification document;
Original or certified supporting records when available;
The receiving office’s form or checklist;
Any proof of authority required if the affiant is acting for an organization; and
A reliable email address for the electronic copy required under the amended paper-notarization rules.

The notary may examine attachments, authority documents, or additional identification. Notarization should be refused when a document is blank, materially incomplete, lacks an appropriate certificate, appears unlawful, or the signer’s identity, understanding, or voluntariness is doubtful.

4. Appear, sign, and take the oath

The affiant—not a relative, messenger, fixer, or representative—must appear. The notary should confirm identity and may ask whether the affiant:

Read and understood the affidavit;
Signed voluntarily;
Understands the language used;
Knows the facts stated; and
Swears or affirms that the contents are true.

A representative cannot ordinarily swear to another person’s personal knowledge. If an authorized corporate officer is the affiant, the affidavit should identify the officer’s position, authority, and basis of knowledge.

5. Inspect the completed affidavit

Before leaving, check that the notary has completed the jurat and that the affidavit bears:

The actual date and place of notarization;
The identity information used, where required;
The notary’s handwritten signature and official seal;
The notary’s name and commission details;
The city or province of commission and commission expiry;
The notarial document, page, book, and series information; and
No unexplained alterations or unfinished blanks.

A legitimate certificate should identify the commissioned notary—not merely a law office, paralegal, or “notarial service.”

Personal appearance and electronic notarization

The governing method depends on the document and the type of notarial commission.

Method	Appearance	Document and signature
Traditional paper notarization	Physical appearance before a commissioned traditional notary	Paper document and wet signature
In-Person Electronic Notarization	Physical appearance before a commissioned Electronic Notary Public	Electronic document and electronic signature through an accredited facility
Remote Electronic Notarization	Live virtual appearance through an accredited facility	Electronic document, electronic identity verification, and electronic signature

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement rather than replace the rules for paper notarization. They cover electronic documents, including qualifying PDF or PDF/A files, and permit both in-person and remote electronic notarization.

For a remote electronic jurat, the affiant must appear through the accredited facility, complete its identity-verification requirements, affix the electronic signature in the Electronic Notary Public’s view, and take the oath. All principals and required witnesses must use their own facility accounts and participate as required.

An ordinary traditional notary cannot make a paper jurat valid merely by watching a video call. The pandemic-era interim rules for remote notarization of paper documents were repealed by the permanent electronic-notarization rules. Consult the Supreme Court’s eNotary Services portal for accredited facilities and official guidance.

Affiants outside the Philippines

The electronic-notarization rules permit limited extraterritorial notarization, but the overseas affiant must be physically within a Philippine embassy, consular office, or office of a Philippine honorary consul during the act. A designated consular officer must confirm the affiant’s presence, while the Electronic Notary Public must be in the Philippines. An overseas affiant cannot use this route from a private home or ordinary foreign office.

Other common options are:

Executing the affidavit before a Philippine consular officer, subject to that post’s appointment, identification, copy, and fee requirements; or
Executing it before a competent foreign notary and obtaining an Apostille from the competent authority of the originating country when the Apostille Convention applies.

An Apostille authenticates the origin of the foreign public document, including the official signature or seal; it does not certify that the affidavit’s factual statements are true. Documents from non-Apostille countries may require the applicable authentication or legalization process. Check the receiving office and the DFA Apostille portal before execution.

Special situations

Joint affidavits

Each affiant must be properly identified, personally appear through the legally permitted mode, sign as required, and take the oath. One affiant cannot complete the jurat for an absent co-affiant. The notarial certificate must truthfully reflect who appeared and when.

A person who cannot physically sign

Physical inability does not automatically prevent notarization. The rules provide a special procedure under which the notary may sign at the person’s direction in the presence of two disinterested and unaffected witnesses, with prescribed signatures and wording. Arrange this with the notary beforehand; it is not a shortcut for someone who is merely absent or unavailable.

Language, literacy, illness, or impaired capacity

Tell the notary in advance if the affiant cannot read, does not understand the document’s language, has a disability affecting communication, or is seriously ill. An interpreter, accessible format, lawful alternative-signature procedure, medical setting, or additional safeguards may be required.

The notary should refuse if there is a reasonable basis to believe that the affiant does not understand the document or is not acting freely. A relative’s instruction cannot replace the affiant’s own understanding and consent.

Judicial affidavits

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

Be prepared in a language known to the witness, with an English or Filipino translation when required;
State the witness’s identifying information;
Identify the examining lawyer and place of examination;
Use consecutively numbered questions and answers;
Explain how the witness acquired the relevant knowledge;
Identify and authenticate attached evidence;
Contain the witness’s signature and a jurat; and
Include the examining lawyer’s sworn attestation against coaching.

Judicial affidavits and exhibits are generally filed and served not later than five days before the applicable pre-trial, preliminary conference, or scheduled hearing. Criminal-case timing and scope have additional rules. Late or defective submissions may be excluded, subject only to the limited relief and fines stated in the rule. The witness must still appear for cross-examination when required.

Complaints and counter-affidavits

Affidavits filed with prosecutors, courts, police agencies, regulators, or administrative bodies follow the rules and deadlines of the particular proceeding. A notarized affidavit does not extend a subpoena, preliminary-investigation, appeal, or filing deadline. Treat the date in the official notice as controlling and seek advice immediately if it is unclear.

Fees, documentary stamp tax, and electronic copies

Notarial fees vary. The notary should display the applicable schedule, disclose the charge, and issue an appropriate receipt. Ask separately about drafting fees, notarial fees, copies, documentary stamps, travel, and electronic-platform charges.

Section 188 of the National Internal Revenue Code, as amended by the TRAIN Law, imposes a ₱30 documentary stamp tax on each certificate issued by a notary public and on certain other certificates not otherwise specifically taxed. A different tax provision or an exemption may apply to a particular document or transaction, so the documentary stamp should not be confused with the notary’s professional fee.

Under the Amended 2004 Notarial Rules, the notary must transmit an electronic copy to each signatory at no additional cost within the prescribed period, unless the signatory waives transmittal. For an affidavit not subject to a separate clerk-of-court duplicate-original deadline, this generally means within five days from completion of the notarial act.

Do not casually waive the electronic copy. Compare it with the paper original. If a material discrepancy affects anyone’s rights, notify the notary promptly in writing and request correction.

What notarization does—and does not do

Proper notarization gives a document the evidentiary character attached by law to a public document and provides an official record of the notarial act. It helps establish the signer’s appearance, identity, signature, oath, and the date of notarization.

It does not:

Guarantee that every statement is true;
Prove the affiant’s credibility;
Cure hearsay or other evidentiary objections;
Validate an unlawful act;
Supply missing legal elements;
Confirm ownership or authority not shown by supporting documents;
Make an affidavit automatically admissible for every purpose; or
Replace the affiant’s appearance for testimony or cross-examination when required.

An irregular notarization may cause the document to lose the presumptions accorded to a properly notarized public document. It does not invariably void every underlying transaction; the result depends on the document, the governing law, and whether notarization is required for validity, enforceability, registration, evidence, or merely convenience.

False affidavits and forged notarizations

Knowingly making an untruthful statement under oath about a material matter may constitute perjury when the legal elements are present. Under Republic Act No. 11594, perjury under Article 183 of the Revised Penal Code is punishable by prision mayor in its minimum period. Additional consequences apply when the offender is a public officer or employee. Forgery, falsification, obstruction, fraud, or other offenses may also apply depending on the facts.

Do not sign:

Facts supplied by someone else that you cannot honestly verify;
A blank or partially blank affidavit;
A backdated or postdated jurat;
An affidavit falsely stating that you appeared before the notary;
A document using another person’s identity; or
A statement altered after you took the oath.

If an honest material error is discovered after notarization, do not erase, overwrite, replace pages, or add text beside the seal. Ask the receiving office whether it requires a corrected, supplemental, or replacement affidavit and have the new document properly executed.

Evidence to preserve

Keep:

The final paper original and a clear scan of every page;
The electronic copy sent by the notary;
The original electronic PDF/PDF-A and validation data for an electronically notarized affidavit;
Copies of the identification and supporting records used;
Drafts showing how material facts were confirmed;
The official receipt and documentary-stamp proof;
The notary’s name, office address, commission details, and notarial entry information;
Appointment confirmations and relevant emails or messages;
Proof of filing, service, delivery, or receipt; and
Any permitted audiovisual record of an electronic notarial act.

Preserve the original electronic file rather than relying only on a printout or screenshot. Printing may remove digital signatures, certificates, timestamps, QR functions, or other information needed to verify authenticity.

Common mistakes to avoid

Using an acknowledgment instead of a jurat;
Signing a paper affidavit before meeting the notary;
Relying on a cedula alone as identification;
Sending only a representative or courier;
Treating an informal video call as valid remote notarization;
Using an uncommissioned lawyer or an expired commission;
Leaving names, dates, amounts, attachments, or ID details blank;
Allowing pages or annexes to be changed after notarization;
Assuming notarization proves ownership, authority, or the truth of every allegation;
Using a generic online template without checking the recipient’s rules;
Missing the underlying case or agency deadline while arranging notarization;
Giving unnecessary personal information to a fixer or unverified website; and
Discarding the emailed copy or failing to compare it with the paper original.

When legal help is urgent

Consult a Philippine lawyer promptly when:

The affidavit concerns criminal accusations, a prosecutor’s subpoena, arrest, or possible self-incrimination;
A filing, hearing, appeal, registration, or agency deadline is near;
The document affects land, inheritance, corporate authority, a substantial loan, immigration, custody, or a waiver of rights;
Someone asks you to swear to facts you did not personally witness or verify;
The affidavit contains an admission that could expose you to civil, criminal, tax, employment, or administrative liability;
A signature, seal, notarial entry, date, or identity appears forged or false;
A document was notarized without your appearance;
The notary’s commission cannot be verified;
Pages were substituted or altered after signing; or
Emergency action may be needed to stop registration, transfer, payment, eviction, detention, or use of a fraudulent document.

If forgery or unauthorized notarization is suspected, preserve the document without writing on it. Obtain a certified copy or certification from the relevant notary, Clerk of Court, or Executive Judge where appropriate; notify the receiving institution in writing; and obtain advice on civil protection, criminal reporting, and any administrative complaint against the lawyer-notary.

Frequently asked questions

Must every affidavit be notarized?

An affidavit is ordinarily a sworn statement, so it must be made before a notary or another officer legally authorized to administer the relevant oath. Some laws or agency procedures accept a different declaration or certification; follow the specific rule rather than assuming that notarization is always required.

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

Not for an ordinary paper jurat. The affiant must personally appear, sign in the notary’s presence, and take the oath. Delivery and collection may be delegated, but the affiant’s appearance and oath cannot.

Are two valid IDs always required?

The general notarial rule requires at least one current official identification document bearing the affiant’s photograph and signature when the affiant is not personally known to the notary. A second ID may be requested to resolve a discrepancy or satisfy another applicable requirement.

Is a cedula a valid notarial ID?

Not by itself. The Supreme Court has ruled that a community tax certificate does not satisfy the competent-evidence-of-identity requirement.

Can an affidavit be notarized online?

Yes, if it is processed as an electronic document by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. An ordinary video call with a traditional notary is insufficient.

Does a notarized affidavit expire?

Notarization has no universal expiry period. The affidavit may become outdated, and a court, agency, bank, or other recipient may impose a recency requirement or filing deadline. Check the recipient’s current rules.

Can I change a notarized affidavit?

Do not alter the notarized original. Material corrections should ordinarily be made through a properly executed corrected, supplemental, or replacement affidavit, according to the receiving office’s requirements.

Does notarization mean the government agrees that the statement is true?

No. The notary administers the oath, verifies identity and appearance, and records the act. Courts and agencies still evaluate the truth, relevance, admissibility, and weight of the statements.

Can a notary refuse to notarize my affidavit?

Yes. A notary should refuse a blank or incomplete document, an improper certificate, an unlawful or immoral transaction, an unidentified signer, or a situation involving suspected coercion, incapacity, fraud, or lack of understanding.

Where can I verify the applicable rules?

Consult the Supreme Court’s Amended 2004 Notarial Rules, Rules on Electronic Notarization, and eNotary Services portal. For documents crossing national borders, use the DFA Apostille portal and the official website of the relevant Philippine embassy or consulate.
