Quick answer

An affidavit is a written statement of facts made under oath or solemn affirmation. For an ordinary paper affidavit in the Philippines, the affiant must personally appear before a duly commissioned notary public or another officer legally authorized to administer the oath, prove identity, sign in that officer’s presence, and swear or affirm that the statements are true.

For an affidavit, the proper notarial act is generally a jurat, usually shown by the words “Subscribed and sworn to before me.” An acknowledgment—which merely confirms that a person voluntarily executed a document—is not a substitute for the oath required for an affidavit.

Do not sign in advance, send only a scanned signature, leave blanks, ask someone else to appear for you, or agree to backdating. Ordinary video calls do not by themselves satisfy the rules. Electronic or remote notarization is valid only when performed by an authorized Electronic Notary Public under the Supreme Court’s prescribed system and procedures.

Notarization proves due execution and gives a document the evidentiary status associated with a public document. It does not make every statement in the affidavit true, cure a false statement, establish ownership, or guarantee that the receiving court or agency will accept the affidavit.

What makes an affidavit legally sworn?

Under the 2004 Rules on Notarial Practice, a jurat requires the affiant, on a single occasion, to:

Personally appear before the notary public and present the affidavit;
Be personally known to the notary or identified through competent evidence of identity;
Sign the affidavit in the notary’s presence; and
Take an oath or affirmation concerning the affidavit.

All four elements matter. A seal and signature placed on a document without the affiant’s appearance, identification, signing, and oath do not create a proper jurat.

A solemn affirmation may be used instead of a religious oath. What matters is that the affiant consciously accepts the legal obligation to tell the truth.

Jurat versus acknowledgment

These acts are often confused, but they serve different purposes.

Notarial act	What the signer does	Typical use
Jurat	Signs before the notary and swears or affirms that the contents are true	Affidavits, sworn statements and verified declarations
Acknowledgment	Personally appears and declares that an already complete document was voluntarily executed as the signer’s act and deed	Deeds, contracts, powers of attorney and other instruments

A document’s title does not control by itself. If a document is intended to be a sworn statement, its notarial certificate and the actual procedure must include an oath or affirmation.

Who may administer the oath?

A commissioned notary public is the usual choice for private transactions. Not every lawyer is automatically a notary: the lawyer must hold a current notarial commission and may act only within the territorial jurisdiction of the commissioning court.

Section 41 of the Administrative Code, as amended, also authorizes specified public officers to administer oaths. These include members of the judiciary, clerks of court and certain national and local officials. Their authority may be limited to official business or matters connected with their functions. A prosecutor may, for example, administer the oath for affidavits properly submitted in a criminal proceeding.

Do not assume that a barangay official, police officer, court employee or government lawyer may notarize any private affidavit. Ask the receiving office whether that officer is authorized for the particular document. The governing provisions appear in the Administrative Code of 1987 and its amendments.

What identification should the affiant present?

If the notary does not personally know the affiant, competent evidence of identity is required. The general rule is at least one current identification document issued by an official agency and bearing the individual’s photograph and signature.

Common examples include a passport, driver’s license, PRC ID and other current government-issued identification satisfying those features. The physical National ID, National ID in paper form and Digital National ID are government-issued proofs of identity. The PSA states that the Digital National ID is valid and sufficient proof of identity in government and private transactions, subject to authentication.

Bring the original ID. Also bring photocopies if requested by the notary or receiving office.

A Community Tax Certificate or cedula by itself is not competent evidence of identity under the notarial rule because it does not bear both the required photograph and signature. The Supreme Court has repeatedly applied this rule, including in its decisions concerning competent evidence of identity.

If the affiant has no qualifying ID

The rules provide a credible-witness alternative:

One credible witness may identify the affiant if that witness is personally known to the notary, personally knows the affiant, and is not a party to or privately interested in the document or transaction; or
Two credible witnesses may be used if neither is interested in the document or transaction, both personally know the affiant, and each presents the required documentary identification.

This is a formal alternative, not an informal endorsement by a companion. Arrange it with the notary beforehand.

What should the affidavit contain?

The exact form depends on its purpose. A generally usable affidavit should contain:

A clear title describing the affidavit;
The affiant’s complete legal name and sufficient identifying details;
Numbered statements of relevant facts;
Dates, places, names and events stated accurately;
A statement explaining the affidavit’s purpose when useful or required;
Properly identified attachments or exhibits;
The affiant’s signature; and
A complete jurat.

Write facts the affiant personally knows. If information came from a record or another person, identify the source rather than presenting it as personal observation. Avoid legal conclusions, exaggeration and unnecessary personal data.

Purpose-specific affidavits may have mandatory wording, witnesses, attachments or agency forms. Examples include judicial affidavits, affidavits of loss, support, consent, discrepancy, adverse claim and heirship. Always obtain the current checklist from the court, agency, bank, school, employer or other intended recipient before execution.

How to prepare and notarize a paper affidavit

1. Confirm the recipient’s requirements

Ask for the current form and checklist. Confirm:

Whether notarization is required;
Whether a particular affidavit form must be used;
Whether supporting records must be attached;
How many originals and photocopies are needed;
Whether the recipient accepts electronic notarization;
Whether witnesses or special identification are required; and
The filing deadline and accepted filing channel.

There is no single nationwide filing deadline or universal “validity period” for all affidavits. The governing statute, procedural rule or receiving office sets those requirements. An affidavit does not automatically expire after three or six months, but an office may require a recently executed affidavit because the facts must remain current.

2. Check every factual statement

Compare names, dates, addresses, account numbers, certificate numbers and descriptions against the original records. If the affidavit concerns a missing document, state only what is honestly known about when, where and under what circumstances it was lost.

3. Assemble the complete document

Attach and label every exhibit mentioned in the affidavit. Remove unintended blank pages and fill all material blanks before notarization. Do not let anyone add substantive language after the oath has been administered.

4. Appear before the proper notary

Go to a notary with a current commission for that territorial jurisdiction. The notary ordinarily acts at the notary’s regular place of work or business. The rules permit limited exceptions within the notary’s territory, including certain public function areas, hospitals where a signer is confined and places where a signer is detained.

5. Present identification and sign before the notary

Show the original qualifying ID. Read the complete affidavit before signing. The notary should administer the oath or affirmation and witness the signature.

If the affiant cannot read, understand or freely execute the document, tell the notary immediately. A notary should not proceed where the signer does not understand the document, lacks apparent capacity or is acting under coercion.

6. Inspect the completed jurat

Before leaving, check that the affidavit bears:

The correct city or municipality and province;
The actual date of appearance and oath;
The affiant’s correct name;
The notary’s signature and legible official seal;
The notary’s current commission information; and
The document, page, book and series entries corresponding to the notarial register.

The jurat must not contain a false date or place. Never accept an antedated or postdated notarization.

7. Keep a complete copy

Scan or photograph every page, including the exhibits and jurat. Preserve the original ID used, payment record, submission receipt, email confirmation, courier record and any instructions received from the intended recipient.

The Supreme Court’s 2025 amendments to the notarial rules strengthened electronic reporting and record safeguards for notaries, including PDF copies and electronic transmission requirements for covered acknowledged instruments. Those are principally duties of the notary, but keeping your own exact copy remains essential.

How to verify the notary

A legitimate seal is not enough if the person had no current authority. Check the notary’s name, commission number, place of commission and commission period. A Philippine notarial commission generally covers a two-year term beginning on January 1 of the commissioning year, unless earlier revoked or ended by resignation.

For an important or disputed document, verify the commission through the Office of the Clerk of Court of the Regional Trial Court that issued it. This is especially important for property, inheritance, corporate, loan and court-related documents.

Warning signs include:

The affiant is told not to appear;
An assistant offers to sign or “process” the jurat without the notary;
The document is notarized outside the notary’s territorial jurisdiction;
No valid ID is requested;
The notary’s commission has expired;
Blank or incomplete papers are accepted;
The stated date or place is false;
Someone offers bulk notarization for absent signers; or
The register details are missing or obviously reused.

Electronic and remote notarization

The Supreme Court’s Rules on Electronic Notarization, A.M. No. 24-10-14-SC, govern in-person electronic notarization and remote electronic notarization of electronic documents.

A valid electronic jurat is not created by emailing a scanned affidavit, pasting an image of a signature or joining an ordinary video call. It must be performed by a duly commissioned Electronic Notary Public using the prescribed identity-verification, secure-signature, audiovisual and recordkeeping procedures.

As of the source check for this article, the Supreme Court’s public eNotary Services page remained marked “Coming Soon.” Before relying on remote notarization, confirm both that the service is operational and that the particular notary and platform are authorized. If the recipient requires a paper original or does not accept an electronically notarized document, use the accepted paper process.

Affidavits executed outside the Philippines

A person abroad generally has two routes:

Personally appear before a Philippine Embassy or Consulate that offers notarial services; or
Execute the affidavit before a competent local notary or authority and complete the apostille or legalization process required for use in the Philippines.

Requirements, appointments, fees, jurisdiction and release times vary by foreign service post. Philippine consular guidance typically requires personal appearance, the original document and valid identification. Check the website of the Embassy or Consulate responsible for the place where the affiant lives.

For a document notarized under foreign law, an Apostille issued by the competent authority of a country that is party to the Apostille Convention will generally replace consular legalization. Different authentication steps apply to documents from non-member countries. Confirm the destination requirements through the DFA Authentication Division and the Philippine receiving office.

An apostille authenticates the origin of the relevant public document or notarial certification. It does not certify that the affidavit’s factual statements are true.

What notarization does—and does not—prove

Proper notarization converts a qualifying private document into a public document for evidentiary purposes, allowing its due execution and authenticity to be recognized without the same preliminary proof normally required for a private document.

That presumption is not conclusive. It may be overcome by clear, convincing evidence of forgery, lack of personal appearance, an expired commission or another serious irregularity. More importantly, notarization does not establish the truth of every factual claim. The Supreme Court has clarified that notarized documents are generally prima facie evidence of due execution and authenticity, not automatically of the truth of their contents. See this Supreme Court decision on the evidentiary effect of notarization.

Defective notarization also does not produce one universal result:

An affidavit may fail as a sworn statement if no valid oath was administered;
A document may lose its status and presumptions as a public document and be treated as a private document requiring proof of authenticity; or
An underlying agreement may remain valid if notarization was not legally required for its validity, although registration, enforceability against third persons or admissibility may be affected.

The result depends on the document, the applicable law and the purpose for which it is offered.

Common mistakes to avoid

Signing the affidavit before meeting the notary;
Using an acknowledgment instead of a jurat;
Relying only on a cedula;
Asking a relative, employee or fixer to appear for the affiant;
Leaving material blanks or unattached exhibits;
Stating assumptions, rumors or legal conclusions as personal knowledge;
Copying an online template without checking the recipient’s required form;
Using inconsistent spellings, dates or civil-status details;
Altering the affidavit after notarization;
Backdating the oath;
Treating a scanned seal as proof of valid notarization;
Assuming every lawyer may notarize anywhere;
Filing only a photocopy when an original is required; and
Waiting until the filing deadline to correct a rejected affidavit.

Evidence to preserve if notarization may be disputed

Keep the following in their original or native electronic form:

The fully notarized affidavit and every exhibit;
Earlier drafts showing what was or was not changed;
The identification presented;
The notary’s name, office address and commission details;
Appointment messages and correspondence;
Receipts and register references;
CCTV information, photographs or witnesses showing personal appearance;
Electronic files with metadata, if electronic notarization was used;
The submission receipt and the exact copy filed; and
Records contradicting an allegedly false statement.

Do not write on, detach pages from or “correct” the disputed original. Make a separate written chronology while events are fresh.

When legal help is urgent

Consult a Philippine lawyer promptly if:

You are being asked to sign facts you do not know or believe;
Someone notarized a document in your name without your appearance;
Your signature, ID or notarial details were forged or misused;
The affidavit concerns a criminal complaint, arrest, domestic violence or child safety;
A filing, appeal, tax, registration or prescription deadline is near;
Land, inheritance, corporate control or a substantial financial obligation is involved;
A court or agency rejected the affidavit;
You need to withdraw or correct a materially inaccurate sworn statement; or
You have received a subpoena, demand letter, prosecutor’s notice or complaint alleging perjury.

Do not simply execute a second affidavit that contradicts the first. A correction, supplemental affidavit or retraction can have serious evidentiary and criminal consequences and should be handled with advice based on the complete record.

Consequences of false statements

Knowingly making a willful and deliberate false statement under oath about a material matter required by law or made for a legal purpose may constitute perjury. An honest mistake is not automatically perjury, but correcting it quickly does not guarantee that liability disappears.

Republic Act No. 11594 substantially increased the penalties under Articles 183 and 184 of the Revised Penal Code. The applicable imprisonment, fine and disqualification consequences depend on the offense, the offender’s status and the sentencing rules. False affidavits may also lead to dismissal of a claim, administrative sanctions, civil liability or prosecution for other offenses, depending on the facts.

Frequently asked questions

Can I sign the affidavit before going to the notary?

For a jurat, no. The affiant must sign in the notary’s presence and then take the oath or affirmation.

Is one valid ID enough?

Generally, at least one current official-agency ID bearing the affiant’s photograph and signature satisfies the notarial definition. The notary or receiving institution may lawfully require additional proof for identity verification or under a purpose-specific rule.

Is a cedula enough?

No. A Community Tax Certificate alone does not bear the photograph and signature required as competent evidence of identity.

Must a lawyer prepare the affidavit?

Not always. A person may prepare a simple factual affidavit, but legal drafting is advisable where rights, liability, court proceedings, property, inheritance, crime or substantial money are involved. The notary’s role does not necessarily include advising the affiant or verifying the truth of every statement.

Can someone notarize the affidavit while I am abroad?

Not by pretending that you appeared in the Philippines. Use an authorized Philippine consular service or the proper foreign notarization and apostille/legalization route. A compliant electronic-notarization process may be available only through an authorized Electronic Notary Public and accepted platform.

Does an affidavit expire?

There is no universal expiration period. The recipient may require a recently executed affidavit, and an affidavit may become unreliable when its facts change. Check the applicable form and current agency instructions.

Does notarization guarantee acceptance?

No. The affidavit can still be rejected for using the wrong form, lacking exhibits, missing a deadline, containing inconsistencies, using an unacceptable filing channel or failing another substantive requirement.

What if the notarization was irregular?

Preserve the original and verify the commission through the appropriate RTC Clerk of Court. Depending on the defect, the affidavit may lose its sworn or public-document status. Obtain legal advice before refiling, confronting the notary or alleging forgery.
