Quick answer

A paper affidavit is generally validly sworn when:

the document is complete;
the affiant personally appears before a duly commissioned notary public or another officer legally authorized to administer the oath;
the affiant is personally known to the officer or properly identified;
the affiant signs the affidavit in the officer’s presence and takes an oath or affirmation that its contents are true; and
the officer completes the jurat and required notarial records.

Bring at least one current government-issued identification document bearing your photograph and signature. A community tax certificate or cedula alone is not competent proof of identity. Do not sign a paper affidavit beforehand unless the notary specifically instructs you otherwise: a jurat requires signing in the notary’s presence.

Electronic notarization is now legally recognized, but only for electronic documents processed by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. Emailing a scan of a wet-signed affidavit or appearing on an ordinary video call does not, by itself, satisfy the rules.

These are the general requirements. A court, prosecutor, bank, employer, school, registry, foreign government, or other receiving office may prescribe a particular form, supporting documents, number of copies, filing method, or deadline.

What an affidavit legally does

An affidavit is a written statement of facts made under oath or solemn affirmation. The person making it is the affiant.

For an ordinary affidavit, the proper notarial act is normally a jurat. Under the 2004 Rules on Notarial Practice, a jurat requires the affiant, on a single occasion, to:

appear personally before the notary;
present the document;
be personally known to the notary or identified through competent evidence of identity;
sign the document in the notary’s presence; and
take an oath or affirmation concerning the document.

An acknowledgment is different. It is commonly used for deeds, contracts, powers of attorney, and similar instruments. The signer acknowledges that a signature was voluntarily affixed and that the document is the signer’s free act or deed. An acknowledgment does not substitute for the oath required in an affidavit. The Supreme Court has expressly distinguished acknowledgments for written acts and deeds from jurats for affidavits and pleadings.

Notarization does not prove that every allegation in an affidavit is true. It establishes the formal notarial facts—such as appearance, identity, signature, and administration of the oath—and gives a properly notarized document the evidentiary character attached to a public document. The factual statements may still be disputed and must still be supported where proof is required.

Requirements for a paper affidavit

The document must be complete

A notary must not notarize a blank or incomplete document or affix a signature or seal to an incomplete notarial certificate. Before going to the notary, check that the affidavit contains:

the correct name or title of the affidavit;
the affiant’s complete and consistent name;
identifying and address information required by the receiving office;
clear, preferably numbered statements of fact;
relevant dates, places, names, and events;
the basis of the affiant’s personal knowledge;
a clear description of any attached records;
a statement that the affidavit is made under oath;
a signature block for the affiant; and
space for a proper jurat.

Do not leave material blanks to be filled after notarization. If a blank is unavoidable because the receiving office will supply information later, ask that office and the notary whether the form can lawfully be completed that way.

The affiant must personally appear

For traditional paper notarization, the actual affiant must appear before the notary. A spouse, employee, messenger, relative, or lawyer cannot take the oath on the affiant’s behalf.

Personal appearance remains necessary even when the notary personally knows the affiant. Personal knowledge may dispense with documentary identification; it does not dispense with appearance, signing, or the oath.

The notary ordinarily performs the act at the notary’s regular place of work and within the territorial jurisdiction of the commissioning court. The rules permit limited exceptional venues within that jurisdiction, including certain public functions, hospital or medical facilities where a person is confined, and places where a person is detained.

Identity must be established

The standard documentary method is at least one current identification document issued by an official agency and bearing the individual’s photograph and signature. Examples recognized under the 2008 amendment include passports, driver’s licences, PRC IDs, government-office IDs, SSS or GSIS cards, senior-citizen IDs, seafarer’s books, and alien registration documents. The document must be current and must allow the notary to identify the person appearing.

The Philippine Identification System Act requires the authenticated PhilID or PhilSys Number to be accepted as proof of identity in government and private transactions. Because some National ID formats do not display a handwritten signature, the notary may need to authenticate the ID electronically or compare another identification document. Bringing a second current ID can prevent delay.

A cedula alone is insufficient. The Supreme Court has repeatedly explained that a community tax certificate is not competent evidence of identity because it does not provide the reliable photograph-and-signature verification required by the notarial rules.

If the affiant lacks acceptable documentary identification, the rules provide a credible-witness procedure:

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

Arrange this with the notary beforehand. Bringing any two companions is not enough.

The affiant must sign and take the oath

For a paper affidavit, the affiant should sign every original to be notarized while physically before the notary. The affiant must then swear or solemnly affirm that the affidavit is true.

The affiant must also sign or place the appropriate mark in the notarial register. The notary records information including the date and time, type of notarial act, document title, affiant’s name and address, identity evidence, fee, and register entry details.

The jurat must be properly completed

After administering the oath, the notary should complete the jurat and affix the official signature and seal. Check that the completed document shows:

the correct place and date of notarization;
language indicating that the affidavit was “subscribed and sworn to” or its proper equivalent;
the affiant’s identity evidence where required;
the notary’s name and signature;
the notarial seal;
the notary’s commission number, commissioning city or province, commission expiry, and office address;
the Roll of Attorneys, PTR, and IBP particulars required by the rules; and
the document, page, book, and series entries corresponding to the notarial register.

A stamp without personal appearance, an oath, a proper register entry, or a valid notarial commission is not a lawful shortcut.

What to bring to the notary

Bring:

the complete, unsigned affidavit;
every original copy that must be notarized;
the original current government-issued ID or IDs;
photocopies of the IDs if requested for the notary’s records;
the original documents referred to or attached to the affidavit;
the receiving office’s prescribed form and written instructions;
proof of authority if signing in an official or representative capacity; and
credible witnesses and their IDs, if the identity-witness procedure has been arranged.

Ask about the fee before the appointment. A notary who charges for services must post a schedule of fees and issue a BIR-registered receipt. There is no safe universal peso estimate because the charge may depend on the authorized fee schedule, document, legal preparation involved, copies, and agreed travel expenses.

How to write a reliable affidavit

State only facts the affiant can honestly swear to

Separate firsthand facts from information learned from someone else. If a statement is based on a record, identify the record and explain how the affiant knows or keeps it. Do not present assumptions, legal conclusions, or rumours as personally observed facts.

Use exact dates where known. If a date is approximate, say so. If the affiant does not remember something, it is safer to state that honestly than to guess.

Use consistent names and details

Names should match the affiant’s identification and relevant records. Explain legitimate differences such as a married surname, suffix, spelling variation, or clerical error. Check addresses, identification numbers, case numbers, property descriptions, account numbers, and dates carefully.

Identify attachments clearly

Label supporting records consistently—for example, “Annex A”—and refer to each attachment in the affidavit. Preserve the unedited originals. Do not attach altered screenshots, cropped conversations that distort context, or re-created records without explaining what they are.

Use language the affiant understands

The affiant must understand the statements and the consequences of swearing to them. A notary must refuse when the affiant’s conduct creates reasonable doubt about that understanding or when the person is not acting freely.

If the affidavit will be submitted to a court or agency, check its language and translation rules. Under the Judicial Affidavit Rule, a judicial affidavit must be in a language known to the witness; if that language is neither English nor Filipino, an English or Filipino translation must accompany it.

Special situations and exceptions

Thumbmark or another mark

A person unable to make an ordinary signature may use a thumbmark or other mark. Under the notarial rules, the mark must be affixed in the presence of the notary and two disinterested and unaffected witnesses. Both witnesses sign, and the notary makes the prescribed notation before completing the jurat or other appropriate notarial act.

Physically unable to sign or make a mark

A notary may sign on behalf of a person who is physically unable to sign or make a mark if that person directs the notary to do so. The signature must be made in the presence of two disinterested and unaffected witnesses, both witnesses must sign, and the notary must add the prescribed notation and complete the proper jurat or acknowledgment.

Physical inability to sign does not remove the requirements of understanding, voluntariness, identity, and administration of the oath.

Government officers administering oaths

Notaries public are not the only officers authorized to administer oaths. Section 41 of the Administrative Code, as amended by Republic Act No. 10755, also grants general authority to specified officials, including members of the judiciary, clerks of court, certain national and local officials, and registrars of deeds. Other officers may have limited statutory authority for matters connected with their official duties.

An affidavit sworn before such an officer is not necessarily “notarized,” but it may satisfy the applicable oath requirement. Confirm that the officer has authority for the particular document and that the receiving office accepts that form of certification.

Conflict or relationship with the notary

A notary is disqualified if the notary is a party to the document, will obtain a prohibited interest or benefit from it, or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by blood or marriage within the fourth civil degree. Use an independent notary if any possible conflict exists.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, supplement the paper-notarization rules. They permit:

In-Person Electronic Notarization, where the principal and witnesses physically appear before an Electronic Notary Public; and
Remote Electronic Notarization, where the participants appear through synchronous videoconferencing using an accredited facility.

Only a commissioned Electronic Notary Public using a Supreme Court-accredited Electronic Notarization Facility may perform these acts. The system handles electronic identity verification, electronic signatures, the electronic notarial certificate and seal, and the required records. A compliant electronic notarial act has the same validity and effect as its paper counterpart.

The electronic rules do not cover paper documents bearing wet signatures or marks, notarial wills, or deposition-taking. A wet-signed document that is merely scanned, emailed, printed, stamped, or shown over an ordinary video call is not transformed into a valid electronic notarization.

An Electronic Notary Public may generally serve principals located in the Philippines. Limited service for a principal abroad is permitted only under the special conditions in the rules, including the principal’s presence within a Philippine embassy, consular office, or honorary consul’s office and confirmation of that location.

Use the Supreme Court’s eNotary Services information and FAQs to confirm available facilities and procedures. Also ask the intended recipient whether its filing system accepts the electronic format.

Affidavits executed abroad

If an affidavit will be signed abroad, determine what the receiving office requires before execution. Possible routes include:

notarization under the law of the country of execution followed by an apostille, when applicable;
authentication or legalization for a non-Apostille Convention destination;
execution before a Philippine embassy or consulate; or
compliant remote electronic notarization under the limited Philippine rules.

Apostille and authentication requirements depend on the document’s origin and country of use. Consult the DFA’s current documentary requirements and the foreign receiving authority. An apostille authenticates the relevant public signature or capacity; it does not certify that the affidavit’s factual allegations are true.

Deadlines and validity

There is no general rule that every affidavit expires after a fixed number of days or months. Its usefulness depends on:

the date-sensitive facts stated in it;
the rule or law requiring it;
the prescribed form;
the receiving office’s recency requirement; and
the deadline for the application, case, or transaction.

An affidavit of loss, undertaking, consent, support, or no-change declaration may therefore be rejected as stale even though no universal “expiry date” exists.

Court-related affidavits can have strict deadlines. Under the [Judicial Affid

Quick answer

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

Present a complete document to a duly commissioned notary public or another officer legally authorized to administer the required oath;
Personally appear before that officer;
Prove identity through competent evidence of identity, unless personally known to the notary;
Sign every original in the notary’s presence;
Swear or affirm that the statements are true; and
Sign or place the required mark in the notarial register.

An affidavit ordinarily requires a jurat, not merely an acknowledgment. A representative cannot appear and take the oath for the affiant. A cedula or community tax certificate alone is not competent proof of identity. An emailed scan, pre-signed paper, or ordinary video call is also not a substitute for proper notarization.

Electronic and remote notarization are now legally available, but only for electronic documents handled by a commissioned Electronic Notary Public through a Supreme Court-accredited Electronic Notarization Facility. Paper documents bearing wet signatures remain governed by the paper-notarization rules.

The office, court, bank, school, employer, or other recipient may impose additional requirements, prescribed wording, supporting documents, filing deadlines, and rules on how recently the affidavit must have been executed.

What makes a document an affidavit

Calling a document an “affidavit” does not make it one. Its essential feature is that an identifiable person—the affiant—adopts the written statements under oath or affirmation before an authorized officer.

A properly prepared affidavit usually contains:

The correct title, case caption, transaction, or agency reference;
The affiant’s full name and relevant identifying details;
Clear, preferably numbered statements of fact;
An explanation of how the affiant knows those facts;
Identification of any attached records or photographs;
The affiant’s signature over a printed name; and
A completed jurat.

There is no single mandatory format for every Philippine affidavit. An affidavit of loss, complaint-affidavit, judicial affidavit, affidavit of support, and affidavit required by a bank or government agency may have very different contents. Always use the recipient’s current form or instructions when one is prescribed.

Jurat and acknowledgment are not interchangeable

For an affidavit, the usual notarial act is a jurat. Under the 2004 Rules on Notarial Practice, a jurat requires the affiant, on one occasion, to:

Appear personally before the notary;
Present the document;
Be personally known to the notary or properly identified;
Sign in the notary’s presence; and
Take an oath or affirmation regarding the document.

An acknowledgment serves a different purpose. The signer appears and declares that an existing signature was voluntarily affixed and that the document is the signer’s free act and deed. It is commonly used for deeds, contracts, and instruments executed in a representative capacity. It does not, by itself, mean that the signer swore to the truth of every factual statement.

The Supreme Court has emphasized this distinction: jurats confirm affidavits and pleadings, while acknowledgments generally cover acts and deeds. Notarization also does not automatically prove that every statement in an affidavit is true; those statements may still be challenged and must carry the evidentiary weight allowed by the applicable rules. See Nolasco v. Cagayan Electric Power and Light Co., G.R. No. 203990.

Requirements for a paper affidavit

Personal appearance is mandatory

The affiant must appear before the notary at the time of notarization. Personal familiarity with the notary does not excuse appearance; it may only dispense with documentary identification.

Do not:

Send a relative, employee, liaison, or messenger to have your affidavit notarized;
Leave a signed affidavit at a notary’s office for later processing;
Ask a notary to stamp a scanned or photocopied wet signature;
Sign an ordinary paper affidavit during a video call with a traditional notary; or
Allow office staff to administer the oath while the notary is absent.

The Supreme Court has disciplined notaries for notarizing documents when the signer did not personally appear, including cases involving scanned or reproduced signatures. See Kiener v. Amores, A.C. No. 9417.

Competent evidence of identity

Unless the affiant is personally known to the notary, identification ordinarily requires at least one current identification document issued by an official agency and bearing the person’s photograph and signature. Examples identified in the rules include passports, driver’s licenses, PRC IDs, and several other government-issued credentials.

Bring the original ID, not merely a photograph or photocopy. The name and other details should match the affidavit. If there has been a change of name or a discrepancy, bring supporting records such as a marriage certificate, court order, or civil-registry document, as applicable.

A cedula or community tax certificate alone is not competent evidence of identity. The Supreme Court has repeatedly applied this rule because a cedula does not provide the safeguards required for reliable identification.

The National ID, ePhilID, Digital National ID, or authenticated PhilSys Number is legally recognized as proof of identity under the Philippine Identification System Act, subject to authentication. Because some National ID formats do not display a handwritten signature, ask the notary in advance about authentication and consider bringing another current government ID to avoid delay.

If the affiant lacks acceptable documentary identification, the notarial rules permit identification through credible witnesses under strict conditions:

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, each personally knows the affiant, and each presents the required documentary identification.

Arrange this with the notary beforehand. A companion who merely met the affiant recently is not enough.

The document must be complete

A notary may not notarize a blank or incomplete document or affix a signature or seal to an incomplete notarial certificate.

Before the oath, check that:

Names, dates, places, amounts, and identifying numbers are correct;
All numbered paragraphs and attachments are present;
No material space has been left blank;
Corrections are clear and properly initialed if the notary permits them;
The facts are stated accurately and without guesses presented as facts; and
Every original copy intended for use is available for signing.

Never sign a blank affidavit or allow another person to fill in material details after notarization. If material information changes, the safer course is to prepare and notarize a corrected affidavit.

The affiant must understand and act voluntarily

The notary must refuse when there is reasonable doubt that the signer understands the consequences of the transaction or is acting freely. Coercion, serious confusion, intoxication, or apparent inability to understand the document can prevent notarization.

Use a language the affiant understands. If the receiving office requires English or Filipino, obtain an accurate translation rather than asking the affiant to swear to wording that the affiant cannot understand. Judicial affidavits have specific language-and-translation requirements.

The affidavit must be signed before the notary

For a paper jurat, the affiant signs the document in the notary’s presence. Bring every original that must be notarized and wait for the notary’s instruction before signing.

The affiant must also sign, thumbmark, or place the appropriate mark in the notarial register. The entry records such matters as the date and time, type of notarial act, document title, principal’s name and address, identity evidence, fee, and other relevant circumstances.

The jurat and notarial details must be complete

Before leaving, inspect the finished affidavit. It should have a jurat showing that the document was subscribed and sworn to or affirmed before the authorized officer. For notarization by a traditional notary, the certificate should include the required venue, date, signature, seal, commission details, commission territory and expiration, office address, Roll of Attorneys number, professional tax receipt particulars, and IBP membership number.

The usual document, page, book, and series entries should not be left blank. Confirm that the place stated in the jurat is where the notarization actually occurred.

Not every lawyer is a notary public. A lawyer must hold a valid notarial commission and ordinarily acts only within the territorial jurisdiction of the commissioning court. The general rule is also that notarization occurs at the notary’s regular place of work or business. Limited exceptions permit notarization at specified locations within the territorial jurisdiction, including certain public functions, hospital or medical confinement, and places of detention.

A notary is disqualified when, among other grounds, the notary is a party to the document or is the principal’s spouse, common-law partner, ancestor, descendant, or relative by affinity or consanguinity within the fourth civil degree.

What to bring to the notary

For a routine paper affidavit, bring:

The complete, unsigned affidavit;
Every original copy that must be notarized;
At least one current government-issued ID acceptable under the rules;
Photocopies of the ID if requested;
Originals or clear copies of attachments referred to in the affidavit;
Documents explaining name or identity discrepancies;
The recipient’s prescribed form or written instructions; and
Payment for the disclosed notarial fee.

If signing for a company or organization, bring proof of your position and authority when relevant. A corporation does not personally take an oath; a natural person with appropriate knowledge and authority executes the affidavit. That person may swear only to facts the person can truthfully adopt.

Ask for the notary’s BIR-registered receipt. The rules require a charging notary to display a schedule of chargeable fees and maintain the required fee records. There is no safe universal peso quotation for every affidavit because the lawful charge and any separate drafting or travel work depend on the applicable fee rules and the service actually requested.

Practical step-by-step process

Ask the recipient for its current requirements. Confirm the form, acceptable language, attachments, number of originals, filing method, and deadline.
Draft only facts you can support. Separate firsthand knowledge from information learned from records or other people. Identify the source when necessary.
Organize supporting evidence. Label attachments consistently and remove unrelated sensitive information when lawful and appropriate.
Review all names and dates. Match the affidavit with IDs, contracts, case records, police blotters, receipts, messages, and other source material.
Find a properly commissioned notary. Confirm that the notarial commission is current and covers the place where the act will occur.
Appear personally with your ID. Do not sign a paper affidavit in advance.
Read the final document. Ask for an explanation or correction before swearing if anything is unclear or inaccurate.
Take the oath or affirmation and sign. Sign each required original and the notarial register as instructed.
Inspect the completed jurat. Check the venue, date, ID details, seal, commission information, and register particulars.
Keep a complete copy. Scan the entire notarized affidavit, including all attachments, before filing or releasing an original.

Electronic and remote notarization

The Rules on Electronic Notarization, A.M. No. 24-10-14-SC, now supplement the paper-notarization rules. They recognize:

In-Person Electronic Notarization, where the principal and witnesses physically appear before an Electronic Notary Public; and
Remote Electronic Notarization, where the required participants appear through synchronous videoconferencing.

These procedures apply to electronic documents and require a commissioned Electronic Notary Public and a Supreme Court-accredited Electronic Notarization Facility. The facility handles the required identity checks, electronic signatures, electronic notarial certificate, electronic seal, records, and security controls. Use the Supreme Court’s eNotary Services portal and FAQs to verify the current system.

The following are not valid substitutes:

Emailing a scanned wet-signed affidavit to a traditional notary;
Pasting an image of a signature into a PDF;
Having an ordinary Zoom or Messenger call without the accredited process; or
Printing an electronically signed file and asking a traditional notary to stamp it as though it had been signed personally.

The electronic rules do not apply to notarial wills, deposition taking, or paper documents and instruments bearing wet signatures or marks. Electronically notarized documents have the same legal effect as corresponding notarial acts under the governing rules, but confirm that the receiving court, agency, registry, or private institution can accept the electronic format through its current filing system.

Special situations

Thumbmark or other mark

A person who cannot make an ordinary signature may affix a thumbmark or another mark in the presence of the notary and two disinterested and unaffected witnesses. The witnesses sign their names, and the notary must make the required notation and complete the appropriate jurat or other certificate.

Physically unable to sign or make a mark

The rules permit a notary to sign on behalf of a person who is physically unable to sign or make a mark, but only at that person’s direction, in the presence of two disinterested and unaffected witnesses, with the prescribed notation and notarial act. Physical inability does not remove the requirements of understanding and voluntary consent.

Affiant outside the Philippines

A document executed abroad may require notarization under the law of the place of execution, Philippine consular notarization, an apostille, or authentication, depending on where it will be used and the receiving office’s rules.

Under the Philippine electronic-notarization rules, a commissioned Electronic Notary Public may perform permitted acts for a principal abroad only under the special extraterritorial conditions in the rules, including the principal’s presence within a Philippine embassy, consular office, or office of an honorary consul and official confirmation of that location.

For a Philippine document intended for foreign use, notarization may be only the first step. Check the current documentary requirements and appointment process on the DFA’s Apostille and Authentication portal and confirm what the destination country or foreign recipient requires. An apostille authenticates the relevant public signature or capacity; it does not certify that every factual statement in the affidavit is true.

Judicial affidavits

A judicial affidavit is not an ordinary do-it-yourself affidavit. Under the Judicial Affidavit Rule, it must contain prescribed information, consecutively numbered questions and answers, the witness’s signature, a jurat, and the examining lawyer’s sworn attestation.

As a general rule, judicial affidavits and exhibits must be filed and served not later than five days before the pre-trial, preliminary conference, or scheduled hearing on a motion or incident. In covered criminal cases, an accused who elects to present judicial affidavits generally has 10 days from receipt of the prosecution’s affidavits to submit the defense affidavits and evidence.

Late submission may be allowed only once under the stated conditions—including a valid reason, lack of undue prejudice, and payment of a court-imposed fine of ₱1,000 to ₱5,000. Do not assume that a defective or late judicial affidavit will be accepted.

Does an affidavit expire?

There is no universal rule that every Philippine affidavit expires after a fixed number of months. Its usefulness depends on:

The date or event described;
The purpose for which it was made;
Whether circumstances have changed;
The recipient’s written rules; and
Any filing or prescription period governing the underlying matter.

An agency, bank, embassy, employer, insurer, or court may require an affidavit executed within a particular period even though no general “expiration date” appears in notarial law. A current affidavit also cannot revive an underlying claim whose legal filing period has already expired.

Notarization should occur on the actual date of personal or authorized electronic appearance. Backdating or using a false venue is improper.

Effect of missing or defective notarization

A properly notarized document generally becomes a public document and benefits from the evidentiary treatment given to duly executed notarized instruments. Defective notarization can strip the document of that public character and leave it as a private document requiring proof of authenticity.

That does not produce the same result in every case:

If notarization is required only for evidentiary convenience, the underlying document may sometimes remain provable as a private document.
If the law requires a public instrument for validity, defective notarization can be fatal. A donation of immovable property is one example discussed by the Supreme Court in Patenia-Kinatac-an v. Patenia, G.R. No. 238325.
If an affidavit is required by a court or agency, an unsigned, unsworn, incorrectly sworn, or noncompliant submission may be rejected, disregarded, or allowed to be corrected only if the governing rule permits.
Notarization does not cure false statements, lack of personal knowledge, missing attachments, absence of authority, or failure to meet a filing deadline.

Never rely on a possible “substantial compliance” exception without checking the particular law, rule, and case record.

Evidence to preserve

Keep:

A complete copy of the signed and notarized affidavit;
All pages and attachments in the form submitted;
The ID used and its validity details, stored securely;
The notary’s receipt and contact information;
Filing receipts, receiving stamps, courier records, or electronic acknowledgments;
Source documents supporting each material statement;
Original messages, photographs, recordings, and files with metadata where relevant;
Drafts showing corrections to accidental errors; and
Any instruction sheet or prescribed form issued by the recipient.

Do not alter the notarized copy. If a correction is needed, preserve the original and obtain advice on whether to execute a corrected or supplemental affidavit.

Common mistakes

Signing a paper affidavit before meeting the notary;
Sending another person to obtain the notarization;
Using only a cedula as identification;
Leaving the ID, venue, date, or notarial details blank;
Using an acknowledgment when the required act is a jurat;
Swearing to facts learned only from rumor without identifying the source;
Attaching incomplete, mislabeled, or altered records;
Using a generic online template despite a prescribed agency form;
Assuming notarization makes every allegation true;
Assuming an affidavit has no filing deadline;
Paying someone who merely stamps documents on the street or outside a verifiable notarial office;
Using a notary with an expired commission or outside the proper territory; and
Treating a scanned paper signature as an electronically notarized document.

When legal help is urgent

Consult a Philippine lawyer promptly if:

The affidavit will start or defend a criminal, civil, labor, tax, immigration, election, land, or administrative case;
A filing, appeal, protest, or prescription deadline is approaching;
Police, prosecutors, investigators, or opposing counsel are asking you to sign;
The affidavit concerns land, inheritance, large debts, corporate authority, custody, abuse, or domestic violence;
Someone is pressuring you to omit, change, or invent facts;
Your signature, ID, or notarial details appear on a document you did not execute;
A notarized document contains a false venue, false appearance, or forged signature;
The affiant has difficulty understanding, communicating, or acting independently;
The affidavit was executed abroad or will be used abroad; or
A court or agency has rejected the affidavit.

Knowingly making a materially false affidavit before an authorized officer, in a case in which the law requires an oath, may constitute perjury. Article 183 of the Revised Penal Code, as amended by Republic Act No. 11594, provides for prision mayor in its minimum period, with the statutory fine and disqualification consequences stated in the law. An honest mistake, ambiguity, or immaterial inaccuracy is not automatically perjury; criminal liability depends on all legal elements and the evidence.

Frequently asked questions

Can I sign the affidavit before going to the notary?

For a paper affidavit with a jurat, no. Sign each original in the notary’s presence.

Can a relative or messenger have it notarized for me?

No. The oath and personal appearance belong to the affiant and cannot be delegated.

Is a cedula enough?

No. A community tax certificate alone is not competent evidence of identity under the current notarial rules.

Are two witnesses always required?

No. An ordinary affidavit does not automatically require two witnesses. Witnesses may be required by a prescribed form or special law, for a thumbmark or assisted-signing procedure, or under the credible-witness method of proving identity.

Does the notary verify that everything in the affidavit is true?

No. The notary performs the prescribed notarial act, verifies identity and appearance, administers the oath or affirmation, and completes the certificate and register. The facts may still be disputed or disproved.

Can an affidavit be notarized online?

Yes, but only as an electronic document through a commissioned Electronic Notary Public using a Supreme Court-accredited facility. An ordinary video call or scanned wet signature is insufficient.

Can a government officer administer the oath instead?

Certain officials have general or subject-specific authority to administer oaths. Many government officers may do so only in matters connected with official business. Confirm that the particular officer and receiving agency have authority for your affidavit. The current statutory list appears in Republic Act No. 10755.

Is an unnotarized affidavit automatically useless?

It is generally not a proper notarized affidavit, but the legal consequence depends on the rule requiring it. A recipient may reject it, a court may allow a limited cure, or the writing may retain some value as a private document. Do not assume correction will be allowed after the deadline.

How long is a notarized affidavit valid?

There is no universal validity period. The recipient’s rules, the nature of the facts, and the deadline for the underlying transaction or case control.
