Introduction

A sworn declaration is a written statement confirmed under oath or affirmation before a person authorized to administer oaths, usually a notary public or other authorized officer. In the Philippines, sworn declarations are commonly used in government transactions, court filings, administrative proceedings, tax matters, business registrations, employment documentation, affidavits of loss, affidavits of support, immigration papers, school records, banking transactions, and many other legal or official processes.

Because a sworn declaration is made under oath, it carries serious legal consequences. The person who signs it is not merely signing a private letter. The signer is affirming that the contents are true, that the document is voluntarily executed, and that the signer may be held liable if the declaration is false.

A recurring issue arises when one person wants or needs to sign a sworn declaration for another. This may happen because the declarant is abroad, ill, elderly, incapacitated, unavailable, illiterate, physically unable to sign, detained, hospitalized, or simply too busy to appear. In Philippine law and practice, the answer depends on the nature of the declaration, the authority of the substitute signer, the personal knowledge required, the type of document, and the rules of the office or tribunal receiving it.

The core principle is this: a sworn declaration is ordinarily personal to the declarant. One person should not sign another person’s sworn statement unless there is clear legal authority, proper form, truthful disclosure of representative capacity, and compliance with notarization or oath requirements.

I. What Is a Sworn Declaration?

A sworn declaration is a written statement made under oath. It may be called by different names, including:

Affidavit;
Sworn statement;
Verified declaration;
Jurat document;
Certification under oath;
Sworn certification;
Notarized declaration;
Verification;
Certification against forum shopping;
Statement under oath;
Joint affidavit;
Affidavit of loss;
Affidavit of support;
Affidavit of undertaking;
Declaration of ownership;
Declaration of income;
Declaration of no pending case;
Declaration of authenticity;
Declaration of identity.

Although names vary, the legal effect is similar when the document requires the signer to swear to the truth of the contents before an authorized officer.

A typical sworn declaration contains language such as:

“I hereby declare under oath…”
“I swear that the foregoing is true and correct…”
“I have read and understood the contents…”
“Subscribed and sworn to before me…”
“Affiant exhibited competent evidence of identity…”
“Under penalty of perjury…”

These phrases signal that the document is not merely signed; it is sworn.

II. The Personal Nature of an Oath

An oath is personal. The person making the statement must generally be the person who appears before the notary or administering officer, presents identification, signs the document, and swears to its truth.

The reason is simple: the oath attaches legal responsibility to the person who swears. The officer administering the oath must be satisfied that the person appearing is the person named in the document and that the person voluntarily signs and swears to it.

A person cannot casually say, “I will swear for someone else,” because the truth of the declaration may depend on the declarant’s personal knowledge, belief, intent, or legal responsibility.

For example, a person generally cannot sign another person’s affidavit stating:

“I lost my passport,” “I personally witnessed the incident,” “I am unemployed,” “I am the owner of this property,” “I have no pending case,” “I received this amount,” “I undertake to support this applicant,” “I certify that I read the complaint and the allegations are true.”

These are statements tied to the declarant’s own knowledge, acts, identity, or responsibility.

III. Difference Between Signing and Swearing

It is important to distinguish between signing a document and swearing to a document.

Signing means writing a signature, mark, or authorized indication of assent.

Swearing means appearing before an authorized officer and affirming the truth of the document under oath.

A person may sometimes be authorized to sign documents for another person, such as under a special power of attorney. But authority to sign does not automatically mean authority to swear to facts that only the principal personally knows.

Thus, even if a person has a power of attorney, the question remains: Is this document the kind that may be executed through a representative, or must it be sworn personally by the actual declarant?

IV. General Rule: A Sworn Declaration Must Be Signed by the Declarant

As a general rule, the person whose sworn statement appears in the document should be the one who signs it and appears before the notary or authorized officer.

This means:

The declarant personally reads or understands the document;
The declarant personally signs or marks the document;
The declarant personally appears before the notary or administering officer;
The declarant personally presents competent evidence of identity;
The declarant personally swears or affirms the truth of the statement.

The notary’s jurat normally states that the document was “subscribed and sworn to” before the notary by the affiant. If the named affiant did not personally appear, the notarization may be defective and may expose the parties to legal consequences.

V. Can Someone Sign a Sworn Declaration on Behalf of Another Person?

In limited situations, yes, but only if the law, the nature of the document, and the receiving office allow it.

A person may sign in a representative capacity when:

The document is not strictly personal to the principal;
The representative has valid written authority, usually through a special power of attorney or board authorization;
The representative signs clearly as attorney-in-fact, authorized representative, guardian, corporate officer, or other lawful capacity;
The representative swears only to matters within their own knowledge or based on records they are authorized to certify;
The receiving agency, court, or private institution accepts representative execution;
The notarial acknowledgment or jurat properly reflects who personally appeared and in what capacity.

A representative should not sign the principal’s name as though the principal personally signed. The proper method is to disclose the representative capacity.

For example:

Juan Dela Cruz, by Maria Dela Cruz, Attorney-in-Fact

Maria Dela Cruz, as Attorney-in-Fact of Juan Dela Cruz

ABC Corporation, represented by Pedro Santos, President

The wording matters because it tells the reader who actually signed and who is legally taking responsibility for the oath.

VI. Documents That Usually Require Personal Execution

Certain sworn declarations are usually personal and should be signed by the declarant personally. These include documents involving personal knowledge, identity, status, acts, qualifications, or criminal/civil liability.

Examples include:

Affidavit of loss;
Affidavit of desistance;
Judicial affidavit of a witness;
Sworn statement of a complainant;
Verification of a pleading based on personal knowledge;
Certification against forum shopping by an individual litigant;
Affidavit of support based on personal undertaking;
Sworn statement of income;
Sworn declaration of unemployment;
Sworn declaration of no pending case;
Affidavit of ownership;
Affidavit of two disinterested persons;
Affidavit of discrepancy;
Affidavit of delayed registration;
Affidavit of legitimation, recognition, or paternity;
Sworn statement for immigration or visa purposes;
Sworn declaration for school, scholarship, or employment eligibility;
Affidavit in criminal or administrative complaints.

In these cases, signing for another person may be rejected or treated as irregular unless a specific rule allows representation.

VII. Documents That May Sometimes Be Signed by a Representative

Some sworn or notarized documents may be signed by a representative if properly authorized.

Examples include:

Tax declarations or submissions by an authorized representative;
Corporate secretary’s certificates;
Board-authorized corporate affidavits;
Business permit applications;
Bid documents signed by authorized representatives;
Real estate transaction documents signed by an attorney-in-fact;
Deeds executed through a special power of attorney;
Administrative forms where representative signing is expressly allowed;
Applications filed by parents or guardians for minors;
Documents signed by legal guardians for incapacitated persons;
Estate-related documents signed by administrators or heirs’ representatives;
Bank or insurance forms signed by authorized agents, where accepted;
Government filings where an authorized representative is allowed.

Even in these cases, the representative must not falsely pretend to be the principal. The signature block and notarization should accurately state the capacity.

VIII. Authority Needed to Sign for Another Person

The most common authority is a Special Power of Attorney or SPA.

An SPA is a document by which one person, called the principal, authorizes another person, called the attorney-in-fact or agent, to perform specific acts on their behalf.

For sworn declarations, a general authorization may not be enough. The SPA should clearly authorize the representative to execute, sign, file, submit, or swear to the specific document or transaction.

A broad phrase such as “to transact with government offices” may help, but some offices require a more specific power.

A safer SPA clause may state:

“To sign, execute, verify, swear to, submit, and file all documents, affidavits, declarations, forms, certifications, undertakings, and other papers necessary or incidental to the transaction, insofar as allowed by law.”

However, even with this clause, the representative should not swear to facts that are exclusively within the personal knowledge of the principal unless the declaration is carefully worded.

IX. Special Power of Attorney Versus General Power of Attorney

A General Power of Attorney authorizes broad management acts. A Special Power of Attorney authorizes specific acts that require express authority.

In Philippine practice, government offices, banks, land registries, courts, and private institutions often require an SPA for important acts, especially those involving execution of documents, sale of property, receipt of money, representation in official transactions, or legal submissions.

For signing a sworn declaration, an SPA is generally safer than a general power of attorney because the receiving office may demand specific authority.

X. Representative Capacity Must Be Disclosed

If a representative signs a sworn declaration, the document should clearly disclose that the signer is acting for another.

Improper form:

Juan Dela Cruz Signature: Maria signs Juan’s name

Proper form:

Juan Dela Cruz By: Maria Dela Cruz Attorney-in-Fact

or:

Maria Dela Cruz Attorney-in-Fact of Juan Dela Cruz

or:

For and on behalf of Juan Dela Cruz: Maria Dela Cruz, Attorney-in-Fact

The jurat or acknowledgment should also identify Maria as the person who appeared before the notary.

A document that makes it appear that Juan personally signed and appeared when Maria actually did so may be misleading and legally dangerous.

XI. The Notary’s Role

A notary public is not supposed to notarize a document unless the proper person personally appears, presents competent evidence of identity, and signs or acknowledges the document according to the required notarial act.

For a sworn declaration, the notary administers an oath or affirmation. The notary must identify the affiant and confirm that the affiant swears to the document.

If the notary notarizes a sworn declaration without the personal appearance of the affiant or proper representative, the notarization may be invalid or defective. The notary may also face administrative liability.

The notary does not merely stamp documents. Notarization converts a private document into one with legal significance and public character, so defects may have serious consequences.

XII. Jurat Versus Acknowledgment

Two common notarial acts are relevant.

A. Jurat

A jurat is used for affidavits and sworn declarations. It states that the affiant personally appeared, signed the document, and swore to its contents.

Typical wording:

“Subscribed and sworn to before me…”

This is the usual form for affidavits.

B. Acknowledgment

An acknowledgment is used for documents where the signer acknowledges that they executed the document freely and voluntarily.

Typical wording:

“Before me personally appeared…”

This is common for deeds, contracts, powers of attorney, and conveyances.

A sworn declaration generally requires a jurat because the signer is swearing to the truth of the contents. Some documents may require both an acknowledgment and sworn statement, depending on the transaction.

XIII. Signing for a Person Who Is Abroad

If the declarant is abroad, the safer practice is for the declarant to execute the sworn declaration before the Philippine Embassy, Philippine Consulate, or a foreign notary, depending on the purpose and acceptance rules.

Possible options include:

Execution before a Philippine consular officer;
Foreign notarization with apostille or consular authentication, depending on the country and document use;
Execution of a special power of attorney authorizing a representative in the Philippines;
Remote preparation followed by personal signing abroad;
Agency-specific online or electronic submission, if allowed.

A person in the Philippines should not simply sign the overseas person’s name on a sworn declaration unless a valid representative arrangement is permitted and properly disclosed.

XIV. Apostille and Consular Documents

Documents executed abroad for use in the Philippines may need authentication. Depending on the country, this may involve an apostille or consular acknowledgment.

If the document is executed before a Philippine consular officer, it is generally treated as a Philippine public or consular document for Philippine use.

If executed before a foreign notary, the document may need apostille or authentication before Philippine offices accept it.

This is especially relevant for SPAs, affidavits, deeds, immigration documents, and property transactions.

XV. Signing for an Illiterate Person

A person who cannot read or write may still execute a sworn declaration, but special care is required.

The document should be read and explained to the person in a language or dialect they understand. The person may sign by thumbmark or mark, and witnesses may attest to the execution.

The notary should ensure that the person understood the document and voluntarily executed it.

Another person should not simply sign for the illiterate person unless legally authorized. If assistance is needed, the proper form should show that the declarant personally appeared and affixed a thumbmark or mark, with witnesses if necessary.

XVI. Signing for a Person Physically Unable to Sign

If a person is physically unable to sign because of illness, disability, injury, paralysis, old age, or medical condition, the person may still execute a sworn declaration through alternative means if mentally competent.

Possible methods include:

Thumbmark;
Mark;
Assisted signature;
Signature by another person at the declarant’s express direction, in the declarant’s presence, and with witnesses, where allowed;
Notarial documentation of the circumstances.

The essential point is that the declarant must understand the document, voluntarily assent, and personally appear before the notary or authorized officer unless a special legal procedure applies.

A medical condition affecting the hand does not automatically authorize another person to swear for the declarant.

XVII. Signing for an Elderly Person

Old age alone does not remove a person’s legal capacity. An elderly person who is mentally competent should sign and swear personally, with assistance if needed.

If the elderly person cannot physically sign, a thumbmark or assisted execution may be used. If the elderly person lacks mental capacity, a guardian or authorized representative may be required, depending on the transaction.

Offices may scrutinize documents involving elderly persons, especially if property, money, waivers, benefits, or inheritance matters are involved.

XVIII. Signing for an Incapacitated Person

If a person lacks legal or mental capacity to understand and execute a sworn declaration, another person cannot simply sign on their behalf.

A legal guardian, judicial guardian, parent, administrator, or other authorized representative may be required, depending on the circumstances.

For minors, parents or legal guardians may sign certain documents. For adults who are legally incapacitated, guardianship proceedings or court authority may be necessary for significant legal acts.

A sworn declaration stating facts personally known only to the incapacitated person may be impossible or improper unless the representative can truthfully declare facts based on their own knowledge, records, or legal authority.

XIX. Signing for a Minor

A minor generally lacks full legal capacity to execute certain legal documents independently. Parents or legal guardians may sign on behalf of minors for many administrative or civil transactions.

However, if the document requires the minor’s own statement, such as a witness affidavit or declaration of personal experience, the minor may need to personally give the statement, with appropriate assistance and safeguards.

For routine matters, a parent may sign as:

[Name of Parent], parent/legal guardian of [Name of Minor]

The declaration should make clear that the parent is declaring facts within the parent’s knowledge or acting in a representative capacity.

XX. Signing for a Corporation or Organization

A corporation cannot physically sign or swear. It acts through authorized officers or representatives.

A sworn declaration for a corporation may be signed by a president, corporate secretary, treasurer, general manager, compliance officer, or authorized representative, depending on the corporation’s bylaws, board resolution, secretary’s certificate, or internal authority.

The signature block should show representative capacity:

ABC Corporation By: Juan Santos President / Authorized Representative

The officer swears based on corporate records, official capacity, and personal knowledge of corporate matters. The officer may be personally accountable for false statements knowingly made under oath.

XXI. Signing for a Partnership or Sole Proprietorship

A partnership may act through a managing partner or authorized partner. A sole proprietorship is not separate from the proprietor, but an authorized representative may transact on behalf of the proprietor if allowed.

Documents should identify the correct capacity:

XYZ Trading, represented by Maria Reyes, Attorney-in-Fact of Pedro Reyes, Proprietor

Reyes & Co. Partnership, represented by Ana Reyes, Managing Partner

The authority should be documented, especially for official filings.

XXII. Verification of Pleadings

In court cases, pleadings may require verification. A verification is a sworn statement that the party has read the pleading and that the allegations are true and correct based on personal knowledge or authentic records.

For an individual litigant, the litigant usually signs the verification. A representative may sign if properly authorized and if the representative has sufficient knowledge or access to authentic records.

For corporations, the verification is signed by an authorized officer who can attest to the matters based on personal knowledge or corporate records.

A defective verification may lead to procedural issues, although courts may sometimes allow correction depending on the circumstances.

XXIII. Certification Against Forum Shopping

A certification against forum shopping is required in many initiatory pleadings. It certifies that the party has not filed another action involving the same issues, that no such action is pending, or that the party will inform the court if one is filed.

For individual parties, the general rule is that the party should personally sign. For corporations or juridical entities, an authorized representative may sign, usually with proof of authority.

A person signing for another without authority may cause dismissal or other adverse consequences.

Because forum shopping certification involves personal responsibility and litigation status, courts scrutinize representative signatures.

XXIV. Judicial Affidavits

A judicial affidavit is the written testimony of a witness. Because it substitutes for direct testimony, it must be the witness’s own statement.

A representative cannot sign a judicial affidavit for a witness. The witness must affirm the truth of the testimony and be available for cross-examination, subject to procedural rules.

Signing someone else’s judicial affidavit is highly improper and may expose the signer and parties to serious consequences.

XXV. Affidavit of Loss

An affidavit of loss is typically personal. The person who lost the item should execute it because the facts of loss are within that person’s knowledge.

If a representative signs an affidavit of loss for another person, the wording must be carefully examined. The representative may truthfully state facts within their own knowledge, such as:

“I am the authorized representative of Juan Dela Cruz. Based on information relayed to me and documents shown to me…”

But many offices may reject this because the loss was personally experienced by Juan. The safer practice is for Juan to execute the affidavit himself, even if abroad or physically limited.

For minors, a parent or guardian may execute an affidavit concerning a lost item, especially if the parent has custody or knowledge.

XXVI. Affidavit of Support

An affidavit of support is usually personal because the sponsor undertakes financial responsibility. The sponsor should personally sign and swear to it.

A representative should not sign an affidavit of support for the sponsor unless the receiving institution expressly allows it and the authority is clear. Immigration offices, embassies, schools, and agencies may reject representative execution because the undertaking is personal.

If the sponsor is abroad, the affidavit should usually be executed abroad before the proper authority.

XXVII. Affidavit of Desistance

An affidavit of desistance is highly personal. It usually states that a complainant no longer wishes to pursue a complaint or has lost interest in prosecution.

Another person should not sign it on the complainant’s behalf. Such a document may be challenged as involuntary, unauthorized, or unreliable.

Because affidavits of desistance can affect criminal, civil, labor, or administrative cases, personal execution is strongly required.

XXVIII. Sworn Statements in Criminal Complaints

A criminal complaint or supporting affidavit requires personal knowledge of facts. A person who witnessed an event must sign their own statement.

A representative may file documents physically, but should not sign witness affidavits for others.

False statements in criminal complaint affidavits may lead to liability for perjury, false testimony, malicious prosecution, or other offenses depending on the circumstances.

XXIX. Sworn Declarations in Government Applications

Government agencies often require sworn declarations for eligibility, income, residence, civil status, ownership, employment, or undertaking.

Whether a representative may sign depends on the agency rules. Some forms expressly allow an authorized representative. Others require the applicant’s personal signature.

Examples of documents that may require personal signature include declarations for benefits, licenses, permits, financial assistance, scholarships, tax exemptions, and identity-related applications.

If the form says “I hereby certify” and identifies the applicant personally, representative signing may be rejected unless a representative section is provided.

XXX. Sworn Declarations for Tax Purposes

Tax filings may be signed by taxpayers or authorized representatives, depending on the form and applicable tax rules. Corporations act through officers. Individual taxpayers may authorize representatives for certain transactions.

However, declarations under oath concerning income, exemptions, withholding, or tax status should be carefully handled. A representative should sign only if authorized and if the law or Bureau of Internal Revenue procedures allow it.

False sworn tax declarations may have civil, administrative, and criminal consequences.

XXXI. Sworn Declarations for Land and Property Transactions

Property transactions often use notarized documents, such as deeds, affidavits, extrajudicial settlement documents, affidavits of self-adjudication, waivers, and declarations of ownership.

A representative may sign property documents if authorized by a valid SPA that specifically covers the property and act involved.

However, affidavits involving personal facts, heirship, possession, marital consent, or ownership may still require personal execution or carefully worded representative statements.

Land registries and government offices may require strict compliance with notarization and authority requirements.

XXXII. Marital Consent and Spousal Signatures

Certain transactions involving conjugal or community property may require spousal consent. One spouse should not sign the other spouse’s sworn declaration or consent unless properly authorized.

For significant property transactions, a specific SPA may be required. The receiving office may demand that the non-signing spouse personally execute consent or a duly notarized and authenticated SPA.

Signing a spouse’s name without authority may invalidate or cloud the transaction and may expose the signer to liability.

XXXIII. Electronic Signatures and Sworn Declarations

Electronic signatures may be valid in many transactions, but sworn declarations have additional requirements. The issue is not only whether the signature is electronic, but whether the oath, identity verification, and notarization requirements are satisfied.

If a document requires notarization or oath, ordinary electronic signing may not be enough unless the applicable rules, platform, or agency procedure recognizes electronic notarization or electronic oath-taking.

A person should not use another person’s electronic signature, login credentials, or scanned signature without authority. Doing so may constitute misrepresentation, falsification, identity misuse, or violation of cybercrime or data privacy rules depending on the facts.

XXXIV. Scanned Signatures

A scanned signature is often used for convenience, but it can be risky in sworn documents.

If the declarant personally approved the document and the receiving office accepts scanned signatures, it may be administratively convenient. However, for notarized affidavits, the person usually must personally appear and sign or acknowledge the document before the notary.

Pasting someone else’s scanned signature onto a sworn declaration without actual authority and oath is dangerous. It may make the document false or defective.

XXXV. Using Another Person’s Name or Signature

Signing another person’s name without authority is legally risky. If done to make it appear that the other person personally signed or swore to the document, the act may constitute falsification or use of a falsified document.

Even if the signer believes the contents are true, the method may still be unlawful if it misrepresents who signed and who appeared before the notary.

Consent matters, but consent alone may not cure the problem if the law requires personal appearance or oath.

XXXVI. Perjury

Perjury may arise when a person makes a willful and deliberate false assertion of a material matter under oath in cases where the law requires an oath.

In the context of signing for another person, perjury concerns may arise when:

The signer swears to facts they know are false;
The signer falsely states that they are the declarant;
The signer causes a document to be notarized as though another person personally appeared;
The declaration contains material falsehoods;
The document is used in a legal, administrative, or official proceeding.

The exact liability depends on the facts and applicable law, but sworn documents should always be treated seriously.

XXXVII. Falsification of Documents

Falsification may be implicated when a person imitates another’s signature, causes it to appear that another person participated in an act when they did not, makes untruthful statements in a narration of facts, alters a document, or uses a falsified document.

In sworn declarations, falsification concerns are especially serious because notarized documents are treated with public significance.

Examples of risky conduct include:

Signing another person’s name without authority;
Presenting a document to a notary while pretending to be the declarant;
Having a document notarized without the declarant’s personal appearance;
Using someone else’s ID to notarize a document;
Backdating or altering notarized documents;
Attaching a signature page from another document;
Submitting an affidavit the named affiant never signed.

Such acts may expose the person to criminal, civil, administrative, or disciplinary consequences.

XXXVIII. Liability of the Representative

A representative who signs a sworn declaration may be liable for their own statements under oath.

If the representative signs as attorney-in-fact and swears that the facts are true, the representative should ensure that:

The authority is valid;
The document accurately states the representative capacity;
The facts are personally known or based on reliable records;
The document does not falsely imply personal execution by the principal;
The representative can explain the basis of the declaration;
The receiving office accepts representative execution.

A representative should avoid signing broad declarations such as “I personally know” or “I personally did” if those facts belong to the principal.

XXXIX. Liability of the Principal

A principal who authorizes another person to sign may also face consequences if the authorization is misused or if the document contains false statements made with the principal’s knowledge or instruction.

However, if the representative acts without authority, exceeds authority, or falsifies the document, the principal may dispute the document.

For this reason, principals should provide clear written instructions and limit the authority granted.

XL. Liability of the Notary

A notary who notarizes a sworn declaration without proper personal appearance, identification, or oath may face administrative sanctions and possible legal consequences.

Notarial defects may also affect the admissibility, credibility, or validity of the document.

Parties should not ask notaries to notarize documents when the named affiant is absent. The convenience of “remote notarization” through informal channels can create serious legal problems if not authorized by applicable rules.

XLI. Proper Wording for Representative Declarations

When representative execution is allowed, the declaration should be carefully worded.

Instead of:

“I, Juan Dela Cruz, personally declare…”

Use:

“I, Maria Dela Cruz, of legal age, Filipino, and residing at [address], being duly sworn, state that I am the duly authorized attorney-in-fact of Juan Dela Cruz under a Special Power of Attorney dated [date]. In such capacity, and based on my personal knowledge and/or official records available to me, I state the following…”

This makes clear that Maria is the affiant, not Juan.

The document may then state:

“This declaration is executed for and on behalf of Juan Dela Cruz, pursuant to the authority granted to me.”

This form reduces the risk of misleading the notary, court, agency, or third party.

XLII. Proper Signature Blocks

A. Individual Representative

MARIA DELA CRUZ Attorney-in-Fact of Juan Dela Cruz

B. Principal Named First

JUAN DELA CRUZ By: MARIA DELA CRUZ Attorney-in-Fact

C. Corporation

ABC CORPORATION By: PEDRO SANTOS President / Authorized Representative

D. Minor

ANA REYES For and on behalf of minor child, Carlo Reyes Mother / Legal Guardian

E. Estate

LUIS GARCIA Administrator of the Estate of Pedro Garcia

The notarial portion should correspond to the person who actually appeared.

XLIII. What the Notarial Portion Should Reflect

For a representative affidavit, the jurat should identify the representative as the affiant.

Example:

“Subscribed and sworn to before me this ___ day of ___ 20__, affiant Maria Dela Cruz personally appeared and exhibited to me her competent evidence of identity…”

If the document is executed by an attorney-in-fact, the notary may also refer to the SPA as proof of authority.

It should not say that Juan personally appeared if Juan did not.

XLIV. When an SPA Is Not Enough

An SPA may authorize signing, but it may not be enough when:

The declaration requires personal knowledge of the principal;
The receiving agency requires personal appearance;
The form expressly prohibits representative signing;
The transaction involves personal qualifications;
The document is a witness affidavit;
The document involves criminal complaint allegations;
The declaration is a personal undertaking;
The matter involves identity, civil status, or personal circumstances;
The oath must be taken by the principal under a specific law or regulation.

In such cases, the principal should personally execute the document or obtain a specific ruling from the receiving office.

XLV. Best Practice: Do Not Sign Another Person’s Name

The safest rule is straightforward: do not sign another person’s name on a sworn declaration.

If representative signing is allowed, sign your own name and state your capacity.

Do not:

Imitate the person’s signature;
Use their scanned signature without clear authority;
Present the document as personally signed by them;
Submit it for notarization as though they appeared;
Use their ID to support notarization;
State facts as personally known if they are not;
Backdate the document;
Ask a notary to notarize without personal appearance.

XLVI. Practical Steps Before Signing for Another Person

Before signing a sworn declaration for someone else, ask:

Does the document require personal execution?
Does the receiving office allow representative signing?
Do I have written authority?
Is a special power of attorney required?
Am I signing my own name and capacity, not imitating the principal?
Are the facts within my personal knowledge or based on records?
Does the notarial wording accurately identify me as the person appearing?
Could this document expose me to perjury or falsification liability?
Will the document be used in court, government, banking, immigration, or property transactions?
Would it be safer for the principal to execute the document personally?

If any answer is uncertain, seek legal advice or ask the receiving office for its written requirement.

XLVII. Alternatives to Signing for Another Person

Instead of signing another person’s sworn declaration, consider:

Have the person personally execute the document before a notary;
If abroad, have the person execute it before a Philippine consulate or foreign notary with proper authentication;
Use an SPA authorizing a representative, if allowed;
Have the representative execute a separate affidavit based on their own knowledge;
Submit a non-sworn authorization letter if the office accepts it;
Use a guardian’s declaration for minors or incapacitated persons;
Ask the receiving office whether personal appearance can be waived;
Use official online procedures if available;
Request reasonable accommodation for disability or illness;
For court matters, seek leave of court or proper procedural remedy.

XLVIII. Sworn Declaration Based on Information and Belief

Sometimes a representative can truthfully declare facts “based on personal knowledge, records, and information made available” rather than pretending to have direct personal knowledge.

This may be acceptable for administrative or corporate matters, but not for all sworn declarations.

A court or agency may reject a declaration if the law requires direct personal knowledge. A representative affidavit based on hearsay may have limited evidentiary value.

Thus, the phrase “information and belief” should be used carefully and only where allowed.

XLIX. Ratification by the Principal

If a representative signed without proper authority, the principal may attempt to ratify the act later. Ratification means the principal adopts or confirms the act.

However, ratification may not cure all defects. It may not cure:

A false notarization;
Lack of personal oath when required;
Perjury or falsification already committed;
A deadline missed because the proper document was not filed;
Agency rejection of defective documents;
Procedural defects in court filings;
Documents requiring personal execution at the time filed.

The safer approach is to execute the document correctly from the beginning.

L. Deadlines and Defective Sworn Declarations

When a sworn declaration is required for a deadline, a defective signature may create serious problems.

Examples include:

Court pleadings;
Appeals;
Government applications;
Bidding documents;
Tax submissions;
Immigration deadlines;
Scholarship or employment requirements;
Benefit claims;
Land registration filings.

A document signed by the wrong person may be rejected. If the deadline has passed, correction may not always be allowed.

This is why authority, form, and notarization should be checked before filing.

LI. Use in Administrative Proceedings

Administrative agencies may accept representative signing if their rules allow it. However, sworn statements used as evidence are usually expected to come from the person with personal knowledge.

For administrative complaints, position papers, and affidavits, the affiant should be the person who knows the facts. A representative may file the papers but should not fabricate personal knowledge.

LII. Use in Labor Proceedings

In labor cases, affidavits and sworn statements may be used to support complaints, position papers, or evidence. A union officer, representative, or lawyer may assist in preparing or filing documents, but the employee or witness should personally sign sworn factual statements.

A company may submit affidavits through HR officers, managers, payroll officers, or authorized representatives who have knowledge of company records.

A person signing for another employee or witness without proper authority may weaken the case and create credibility problems.

LIII. Use in Immigration and Travel Documents

Immigration-related affidavits are often personal. Affidavits of support, consent to travel, relationship declarations, and sponsorship declarations may require personal execution by the person making the undertaking.

For minors traveling abroad, parental consent documents should be executed by the parent or legal guardian. A representative cannot casually sign a parent’s consent unless properly authorized and accepted by the relevant authority.

Because immigration documents are closely scrutinized, representative signing should be avoided unless expressly permitted.

LIV. Use in Banking and Financial Transactions

Banks are strict about signatures, identity, authority, and notarization. A sworn declaration used for banking purposes may be rejected if signed by a representative without proper SPA or board authority.

Documents involving loans, waivers, deceased depositor claims, lost passbooks, credit card disputes, or account closures may require personal execution or specific authority.

Bank forms should be followed exactly.

LV. Use in Insurance and Benefits Claims

Insurance companies, SSS, GSIS, PhilHealth, Pag-IBIG, and other benefit administrators may require sworn declarations for claims, beneficiaries, loss, dependency, or identity.

A representative may assist, but the claimant or beneficiary may need to personally sign declarations. For minors or incapacitated beneficiaries, guardians or parents may sign with supporting documents.

False declarations in benefit claims may lead to denial, recovery of benefits, administrative action, or criminal complaints.

LVI. Use in School and Employment Documents

Schools and employers may require sworn declarations for enrollment, scholarships, good moral standing, income, guardianship, employment, clearances, or disciplinary matters.

Parents may sign for minors in appropriate cases. Employees generally should personally sign employment-related sworn declarations concerning their own status, conduct, or obligations.

A supervisor, HR officer, or family member should not sign an employee’s sworn declaration unless the form allows representative signing.

LVII. Risks of “For Convenience” Signing

Many problems arise from seemingly harmless convenience practices:

A family member signs because the declarant is busy;
An employee signs for a manager;
A spouse signs for the other spouse;
A secretary signs for an officer;
A fixer signs for an applicant;
A lawyer’s staff signs for a client;
A scanned signature is pasted to meet a deadline;
A document is notarized without personal appearance.

These practices may seem routine, but they can create serious legal consequences when the document is later questioned.

LVIII. How to Correct an Improperly Signed Sworn Declaration

If an improper sworn declaration has already been signed or filed, the proper response depends on the situation.

Possible corrective steps include:

Withdraw the defective document;
Execute a corrected sworn declaration;
Submit a supplemental affidavit explaining the error;
File a motion to admit corrected verification or certification, if in court;
Notify the receiving agency;
Have the true declarant personally execute the document;
Attach proper SPA or proof of authority;
Correct the notarization, if possible;
Avoid using the defective document further;
Seek legal advice if the document contains false statements or was notarized improperly.

Do not alter the already notarized document secretly. Alteration may create a separate problem.

LIX. Practical Examples

Example 1: Lost ID of an Adult Abroad

Juan is in Canada and lost his Philippine ID. His sister in Manila wants to sign an affidavit of loss for him.

Best practice: Juan should execute the affidavit abroad before the proper authority, or execute an SPA if the receiving office allows a representative. The sister should not sign Juan’s name or make it appear that Juan personally appeared before a Philippine notary.

Example 2: Elderly Parent Cannot Write

Maria’s elderly mother understands everything but cannot hold a pen.

Best practice: The mother should personally appear before the notary and affix a thumbmark or mark, with assistance and witnesses if necessary. Maria should not simply sign the mother’s name.

Example 3: Corporation Filing a Sworn Undertaking

ABC Corporation must submit a sworn undertaking to a government office.

Best practice: An authorized officer signs for the corporation, with board authority or secretary’s certificate if required.

Example 4: Court Complaint Verification

A plaintiff is abroad and asks a cousin to sign the verification.

Best practice: The plaintiff should personally execute the verification abroad or execute a proper SPA if representative verification is legally acceptable. The cousin should not sign unless authorized and able to truthfully verify based on personal knowledge or authentic records.

Example 5: Minor’s School Declaration

A school requires a sworn statement concerning a minor student’s residency.

Best practice: A parent or legal guardian may sign if the school allows it, stating their relationship and basis of knowledge.

LX. Sample Representative Affidavit

Republic of the Philippines [City/Municipality]

AFFIDAVIT OF AUTHORIZED REPRESENTATIVE

I, [Name of Representative], Filipino, of legal age, with address at [address], after being duly sworn, state:

I am the duly authorized attorney-in-fact of [Name of Principal] under a Special Power of Attorney executed on [date], a copy of which is attached to this affidavit.
Pursuant to said authority, I am authorized to represent [Name of Principal] in connection with [describe transaction].
I am executing this affidavit in my representative capacity and based on my personal knowledge, official records, documents provided to me, and authority granted by the principal.
[State facts carefully. Avoid saying the representative personally did something if the principal did it.]
I execute this affidavit for the purpose of [purpose] and for whatever lawful purpose it may serve.

IN WITNESS WHEREOF, I have signed this affidavit on [date] at [place].

[Signature] [Name of Representative] Attorney-in-Fact of [Name of Principal]

SUBSCRIBED AND SWORN to before me this [date], affiant [Name of Representative] personally appearing and exhibiting competent evidence of identity.

LXI. Sample SPA Clause for Sworn Documents

A Special Power of Attorney may include language such as:

“To represent me before any government office, court, tribunal, bank, private entity, or other institution in connection with [specific transaction]; to sign, execute, submit, verify, swear to, and file all forms, affidavits, declarations, certifications, undertakings, pleadings, and other documents necessary or incidental to said transaction, insofar as permitted by law; to receive notices, submit supporting documents, and perform all acts necessary to carry out this authority.”

This clause should be adapted to the transaction. For property, banking, litigation, or high-value matters, more specific language is often needed.

LXII. Checklist for a Valid Representative Sworn Declaration

Before accepting or using a representative sworn declaration, check:

Is representative signing allowed?
Is there written authority?
Is the authority specific enough?
Is the representative the actual affiant?
Does the signature block disclose the capacity?
Does the jurat identify the person who actually appeared?
Are the facts within the representative’s knowledge or records?
Is the SPA attached or available?
Does the receiving office accept the format?
Are there deadlines that require strict compliance?
Does the document avoid false statements of personal appearance?
Was the oath properly administered?

LXIII. Checklist for Notarization

For notarization of a representative sworn declaration:

The actual signer must personally appear;
The signer must present competent evidence of identity;
The signer must swear or affirm the document;
The document must identify the signer’s capacity;
The notary should not state that the principal appeared if only the representative appeared;
The notary may ask for proof of authority;
The notarial register should reflect the correct affiant;
The document should not contain blank spaces;
The date and place should be accurate;
Attachments should be identified if material.

LXIV. Red Flags

Avoid or question the transaction if:

Someone asks you to sign another person’s name;
The named affiant will not personally appear before the notary;
The notary says personal appearance is unnecessary;
The document states facts you do not know;
The form has no space for representative capacity;
The receiving office requires personal signature;
The document will be used in court or immigration proceedings;
The principal is incapacitated and no guardian authority exists;
Someone asks you to use another person’s ID;
The document is backdated;
The declaration contains false or exaggerated statements;
The signature is scanned without clear authority.

LXV. Frequently Asked Questions

1. Can I sign an affidavit for my spouse?

Usually not if the affidavit concerns your spouse’s personal knowledge or personal undertaking. You may sign as attorney-in-fact only if allowed, properly authorized, and clearly stated.

2. Can I sign my parent’s sworn declaration?

Only in limited circumstances. If your parent is mentally competent, your parent should generally sign personally, using a thumbmark or assisted execution if physically unable to sign. If your parent is incapacitated, proper guardianship or authority may be needed.

3. Can I sign for someone abroad?

Do not sign their name. The person abroad should execute the document before the proper foreign or consular authority, or issue an SPA if representative signing is allowed.

4. Is a special power of attorney enough?

Not always. An SPA authorizes representation, but some sworn declarations are personal and must be signed by the declarant.

5. Can I use a scanned signature?

Only if the transaction allows it and the signer actually authorized it. For notarized sworn declarations, personal appearance and oath are usually still required.

6. What happens if I sign another person’s name?

You may face rejection of the document and possible liability for falsification, perjury, or use of a falsified document, depending on the facts.

7. Can a representative swear to facts based on records?

Sometimes, especially for corporate or administrative matters. The declaration should say that it is based on records and representative authority, not personal acts of the principal.

8. Can a lawyer sign a client’s sworn declaration?

A lawyer may sign pleadings as counsel, but the client generally signs sworn verifications, certifications, affidavits, or personal declarations unless rules allow otherwise. A lawyer should not sign the client’s sworn factual statement as if the lawyer were the client.

9. Can a secretary sign for a company officer?

Only if authorized and if the receiving office allows it. Otherwise, the proper corporate officer or authorized representative should sign.

10. Can the defect be corrected later?

Sometimes, but not always. A false notarization or missed deadline may create serious consequences. Correct execution from the start is safer.

LXVI. Key Legal Principles

The main principles are:

A sworn declaration is personal because it is made under oath.
The person who swears must generally be the person who signs and appears before the notary.
Authority to sign is not always authority to swear.
Representative signing must be expressly allowed or legally justified.
A representative should sign their own name and disclose their capacity.
The notarial portion must identify the person who actually appeared.
Personal declarations, witness affidavits, and undertakings usually require personal execution.
SPAs help but do not cure documents that legally require personal oath.
Signing another person’s name can create falsification and perjury risks.
Defective sworn declarations may be rejected and may affect legal rights.

Conclusion

Signing a sworn declaration on behalf of another person in the Philippines is not a simple matter of convenience. Because the document is made under oath, the law requires honesty, personal responsibility, proper authority, and accurate notarization.

The general rule is that the declarant should personally sign and swear to the declaration. A representative may sign only when representation is legally allowed, supported by proper written authority, and clearly disclosed in the document. Even then, the representative should swear only to matters within personal knowledge, official records, or authorized capacity.

The safest practice is never to sign another person’s name on a sworn declaration. If representation is necessary, use the proper form: disclose the authority, sign as attorney-in-fact or authorized representative, attach the SPA or proof of authority, and ensure that the notarial portion identifies the actual person who appeared. When the declaration involves court filings, criminal complaints, affidavits of loss, affidavits of support, immigration documents, property transactions, or personal undertakings, personal execution by the true declarant is usually the safer and legally sound approach.
