In Philippine law, a Special Power of Attorney (SPA) is a written authority by which one person, the principal, authorizes another, the agent or attorney-in-fact, to perform specific acts on the principal’s behalf. It is widely used in property transactions, banking, litigation support acts, business dealings, and personal affairs where the principal cannot act personally.

A recurring question is whether the attorney-in-fact, once armed with an SPA, may delegate that authority to another person. The short legal answer, under Philippine civil law principles, is: generally no, unless the principal expressly or impliedly allows it, or the nature of the agency makes delegation necessary or customary.

But that short answer hides many important distinctions. In practice, the validity of a delegation depends on the wording of the SPA, the nature of the act, the law on agency under the Civil Code, the presence or absence of the principal’s consent, and the consequences to third persons. In many cases, the problem is not merely whether a substitute was appointed, but whether the substitute’s act binds the principal, whether the original attorney-in-fact remains liable, and whether the transaction itself can later be attacked as unauthorized.

This article explains the governing Philippine rules in detail.

I. The Legal Nature of a Special Power of Attorney

An SPA is a species of agency. The attorney-in-fact is not acting by personal right, but by representative authority. Whatever power the attorney-in-fact has comes only from the principal. That is why the scope of authority is strictly construed, especially when the SPA covers acts of ownership or disposition.

Under the Civil Code, agency may be general or special. A special agency is required for certain acts, especially those involving dominion or acts that may materially affect the principal’s rights or property. Examples include:

selling real property
making gifts
entering into compromises
borrowing or loaning money in some circumstances
creating or conveying real rights
making payments not usually considered acts of administration
binding the principal in acts that the law requires to be specifically authorized

In Philippine practice, an SPA is commonly required not merely as evidence of authority, but as a legal condition for validity or enforceability of the representative act.

Because an SPA is based on trust and confidence, the law generally expects the designated attorney-in-fact to act personally.

II. The General Rule: Delegation Is Not Allowed

The basic rule in agency is that the agent must act personally. The attorney-in-fact cannot simply pass the authority to someone else as though it were a transferable right.

This rule exists for an obvious reason: the principal chose the attorney-in-fact because of personal trust, judgment, reliability, skill, or convenience. The principal may be willing to authorize one specific person, but not another.

So, in Philippine law, an attorney-in-fact under an SPA cannot delegate or substitute another person to perform the authorized acts unless delegation is permitted.

That means:

the power to act comes from the principal, not from the attorney-in-fact
the attorney-in-fact cannot enlarge the authority granted
the attorney-in-fact cannot create a new representative of the principal by personal choice alone, unless legally allowed

If the SPA is silent, the safer rule is that substitution is disallowed, especially for acts requiring special confidence or exact compliance.

III. The Civil Code Rule on Appointment of a Substitute

Philippine law does recognize that an agent may, in some cases, appoint a substitute. But this is not a free or absolute right.

The Civil Code allows the agent to appoint a substitute if the principal has not prohibited it. However, the consequences differ depending on what the principal authorized.

The usual framework is this:

1. If the principal expressly allows substitution

If the SPA or other authority expressly states that the attorney-in-fact may:

appoint a substitute,
delegate performance,
designate another representative,
or act “with power of substitution,”

then substitution is generally valid, subject to the limits of the authority given.

In that case, the substitute’s authority still comes, in legal effect, from the principal through the permitted mechanism. The original attorney-in-fact must still act within the terms of the SPA and the law.

2. If the principal prohibits substitution

If the SPA states that the authority is personal, non-delegable, or that the attorney-in-fact has no power to appoint a substitute, then any attempted delegation is unauthorized.

An act performed by the supposed substitute may not bind the principal unless the principal later ratifies it.

3. If the SPA is silent

If the SPA does not say anything about substitution, the Civil Code allows some room for appointment of a substitute, but this must be read carefully and cautiously in the Philippine setting.

Even if substitution is not expressly prohibited, the attorney-in-fact is not automatically free to transfer all powers indiscriminately. The better view is:

substitution may be possible in matters where delegation is not inconsistent with the trust reposed
but it is far more restricted when the act is one requiring special confidence, discretion, personal judgment, or specific written authority

In other words, legal possibility does not mean practical safety. For highly sensitive acts, silence is not a reliable basis for delegation.

IV. Distinguishing “Substitution” From Ordinary Assistance

Not every use of another person amounts to an unlawful delegation.

An attorney-in-fact may often use clerical, ministerial, or mechanical assistance without transferring legal authority. For example, the attorney-in-fact may ask another person to:

prepare documents
type and print forms
arrange meetings
obtain tax clearances
line up documentary requirements
physically deliver papers
coordinate with a registry, bank, or government office

These acts are different from delegating decision-making or representative authority.

The key distinction is this:

Permissible assistance: another person helps perform supporting tasks, but the attorney-in-fact remains the one who decides, signs, appears, and assumes responsibility.
Impermissible delegation: the attorney-in-fact attempts to authorize another person to stand in his or her place as the principal’s representative.

Philippine law is much more tolerant of the first than the second.

V. Why SPAs Are Strictly Construed

A special power of attorney is not interpreted loosely. The authority granted is often read strictly because it may involve acts of ownership or major legal consequences.

For example, authority:

to administer property does not necessarily include authority to sell it
to negotiate does not necessarily include authority to conclude a binding sale
to collect money does not necessarily include authority to compromise or waive claims
to process documents does not necessarily include authority to sign deeds

For the same reason, authority to act under an SPA does not naturally include authority to delegate, unless such power appears from the document, the nature of the task, usage, or necessity.

The more extraordinary the act, the more specific the authority must be.

VI. Acts That Especially Require Personal and Specific Authority

Delegation is particularly problematic where the SPA concerns acts such as:

sale or mortgage of real property
execution of deeds of absolute sale, donation, or partition
compromise agreements
waiver or renunciation of rights
extra-judicial settlement participation
borrowing substantial sums
creating liens or encumbrances
acceptance or repudiation of inheritance in sensitive settings
acts involving family property, conjugal property, or co-owned property
representation before agencies or institutions that themselves require a specific SPA naming the representative

In these situations, even when substitution is not expressly forbidden, an attempted delegation may be attacked because the principal’s consent to the specific representative is often crucial.

VII. “Power of Substitution”: What It Means

Some SPAs state that the attorney-in-fact is granted authority “with full power of substitution and revocation” or “with power to appoint substitutes or sub-agents.”

This clause is important. It usually means the attorney-in-fact may designate another person to perform the authorized acts. But even then, several rules remain:

1. The substitute cannot have broader powers than the original attorney-in-fact

The substitute’s authority cannot exceed what the SPA originally granted.

2. The substitution must stay within the terms of the SPA

If the original SPA authorizes sale of one particular property, the substitute cannot sell a different property.

3. If form is legally required, the substitution should also be in proper form

If the original act requires written authority, especially notarized authority, the substitution should be documented in a way that clearly establishes the substitute’s authority. Informal oral substitution is dangerous and often inadequate.

4. The original attorney-in-fact may remain liable

If the substitute was chosen improperly, incompetently, or in bad faith, the original attorney-in-fact may answer to the principal.

VIII. Liability of the Attorney-in-Fact Who Appoints a Substitute

Even when the law allows substitution, the original attorney-in-fact does not necessarily escape responsibility.

Under agency principles, liability depends on how the substitute was appointed.

A. If substitution was authorized without naming a specific substitute

If the principal allowed substitution but did not designate the substitute personally, the original attorney-in-fact may be liable if the chosen substitute was:

notoriously incompetent
insolvent, when solvency matters
untrustworthy
manifestly unfit for the task

The law protects the principal from careless delegation.

B. If the principal named the substitute

If the principal himself designated the substitute, the original attorney-in-fact generally bears less responsibility for the substitute’s later conduct, because the choice came from the principal.

C. If substitution was prohibited

If the attorney-in-fact appoints a substitute despite prohibition, the attorney-in-fact may be liable for damages and the supposed substitute’s acts may be ineffective against the principal absent ratification.

IX. What Happens if an Unauthorized Substitute Acts?

This is where disputes usually arise.

Suppose the attorney-in-fact, without valid authority to delegate, authorizes another person to sign a deed, sell property, receive money, or otherwise transact in the principal’s name. Several consequences may follow.

1. The act may be unenforceable or not binding on the principal

Since the substitute had no valid authority from the principal, the principal may deny being bound.

2. The document may be attacked for lack of authority

In real estate and high-value transactions, this can lead to cancellation suits, annulment actions, damages claims, or title disputes.

3. Third persons bear risk

Those dealing with an agent must ascertain the existence and extent of authority. If the instrument does not clearly authorize delegation, the third person who relies on a substitute acts at legal risk.

4. Ratification may cure the defect

If the principal later approves the unauthorized act, expressly or impliedly, ratification may validate it from the standpoint of agency law. But ratification should be clear and is often itself subject to formal requirements in practice.

X. Delegation in Real Property Transactions

This is one of the most important practical applications in the Philippines.

A sale of land or an interest in land through an agent generally requires specific authority. If the SPA names X as attorney-in-fact to sell a parcel of land, X ordinarily cannot allow Y to sign the deed instead unless:

the SPA expressly allows substitution, and
the substitution is validly made, and
the authority clearly covers the act done

If X merely signs a private authorization to Y saying, “I authorize Y to sign for me under the SPA,” that is often legally precarious.

Why? Because the actual authority to sell belongs to the principal’s chosen representative. A further transfer of that authority is not lightly presumed, especially where title to real property is involved.

In conveyancing practice, registries, banks, and buyers often insist on one of two safer routes:

the principal executes a new SPA directly in favor of the new representative, or
the original SPA expressly and unmistakably grants power of substitution, and the substitution is formally documented

Anything less invites later challenge.

XI. Delegation in Banking and Financial Transactions

Banks are typically conservative about SPAs. Even if civil law might tolerate some forms of substitution, banks often require strict documentary compliance.

Thus, where an SPA authorizes one attorney-in-fact to withdraw funds, encash checks, open or close accounts, or negotiate instruments, the attorney-in-fact usually cannot appoint another to do so unless the bank accepts the delegation and the SPA expressly supports it.

As a practical matter, institutional rules may be stricter than the broadest possible reading of agency law. So even where delegation might arguably be valid in principle, it may still be rejected operationally.

XII. Court and Litigation-Related Contexts

An attorney-in-fact under an SPA is not the same as a lawyer. The SPA may authorize representation for certain non-lawyer acts, but it does not permit the practice of law.

In litigation-related matters:

the attorney-in-fact may verify pleadings or sign certifications only where law and jurisprudence allow and where authority is properly shown
representation in court as counsel requires a licensed lawyer
authority to compromise a case generally requires special authority
delegation by an attorney-in-fact in this setting is especially sensitive

If the attorney-in-fact is not the litigant and has only limited authority, any attempt to further delegate may be viewed strictly.

XIII. Can the Attorney-in-Fact Appoint a “Sub-Agent”?

In agency law, a substitute is sometimes described as a sub-agent. The terminology matters less than the substance.

A sub-agent or substitute may be possible if:

the principal consented,
the nature of the business requires it,
the usage of trade permits it,
or the task is not one involving pure personal confidence

But again, in SPA practice in the Philippines, especially for high-stakes transactions, courts and institutions look first to the instrument itself. If the SPA does not clearly allow a sub-agent, reliance on generalized delegation theories is risky.

XIV. Express, Implied, and Necessary Delegation

Delegation can arise in three broad ways:

1. Express delegation

This is the clearest case. The SPA expressly states the attorney-in-fact may appoint a substitute.

2. Implied delegation

This may arise from the nature of the authority or the customs of the business. For example, a business agent may, in some settings, use subordinate personnel for ordinary steps in carrying out a mandate.

3. Necessary delegation

Where the task cannot reasonably be accomplished without entrusting a subordinate with part of the execution, some limited delegation may be implied by necessity.

But in Philippine SPA disputes, implied or necessary delegation should be invoked carefully. It is much easier to justify in ordinary commercial administration than in acts of strict dominion like sale, mortgage, waiver, or compromise.

XV. Ratification by the Principal

Even if the attorney-in-fact had no right to delegate, the principal may later ratify the substitute’s acts.

Ratification may be:

express, such as signing a confirmation or issuing a new authority
implied, such as knowingly accepting benefits of the transaction without objection

Still, ratification should not be assumed lightly. In transactions involving real property or formal documents, prudent practice demands express written ratification.

Without clear ratification, the transaction remains vulnerable.

XVI. Effect on Third Persons

Third persons dealing with an attorney-in-fact must verify:

whether an SPA exists
whether it is authentic and duly executed
whether the authority covers the specific act
whether there is any power of substitution
whether the person actually signing or appearing is the one named in the SPA
whether any substitution was validly made

A buyer, lender, bank, or counterparty who overlooks these issues may later find that the principal disowns the act.

Philippine law does protect good faith in certain settings, but good faith does not create authority where none exists. A forged or unauthorized act remains vulnerable even if a third person acted honestly.

XVII. Drafting Guidance: How to Avoid the Problem

The best solution is prevention.

If the principal wants the attorney-in-fact to be able to designate another person, the SPA should say so clearly. It should specify:

whether substitution is allowed
whether it is full or limited
whether the substitute may perform all or only certain acts
whether the attorney-in-fact may revoke the substitution
whether multiple substitutes may be appointed
whether the attorney-in-fact remains personally liable for the substitute’s acts

Examples of safer drafting concepts include:

“with power to appoint a substitute for all or any of the powers herein granted”
“with limited power of substitution solely for ministerial acts”
“without power of substitution”
“authority is strictly personal and non-delegable”

Precision matters. Ambiguity creates litigation.

XVIII. Best Practical Rule in the Philippines

Even though agency law allows some room for substitutes, the best practical rule in Philippine legal work is this:

Do not assume that an attorney-in-fact under an SPA may delegate authority unless the SPA clearly allows it.

This is especially true for:

land transactions
conveyances
mortgages
settlements
waivers
bank transactions
inheritance matters
any act requiring notarized or special authority

When in doubt, the safest course is for the principal to execute a new SPA directly in favor of the person who will actually act.

That avoids arguments over:

unauthorized delegation
defective substitution
non-binding signatures
institutional rejection
future challenges by heirs, co-owners, buyers, or creditors

XIX. Frequently Encountered Misconceptions

Misconception 1: “Once I am attorney-in-fact, I can authorize anyone to act for me.”

False. You are not the owner of the authority. You only hold delegated authority from the principal.

Misconception 2: “A general statement authorizing me to manage everything includes the right to appoint another.”

Not necessarily. Management authority and substitution authority are distinct.

Misconception 3: “If the substitute signs and the other party accepts, the act is valid.”

Not necessarily. The principal may still challenge it for lack of authority.

Misconception 4: “Notarization cures lack of authority.”

False. Notarization helps prove execution of a document; it does not create authority that the principal never granted.

Misconception 5: “A verbal instruction from the attorney-in-fact is enough.”

Usually unsafe, and often inadequate, especially where the underlying act itself requires written special authority.

XX. A Practical Summary of the Philippine Rule

Under Philippine law, an attorney-in-fact under a Special Power of Attorney generally cannot delegate the authority entrusted to him or her, because agency is founded on personal trust and representation. Delegation or substitution is valid only in limited situations, chiefly where:

the principal expressly authorized substitution,
the principal did not prohibit it and the nature of the agency permits it,
the delegation concerns merely ministerial assistance rather than true representative authority,
or the principal later ratifies the act.

Even where substitution may be legally arguable, it is risky in transactions involving real property, substantial rights, formal institutions, or acts requiring strict special authority. The substitute can never acquire more power than the original attorney-in-fact, and the original attorney-in-fact may remain liable for improper selection or unauthorized delegation.

The safest legal and transactional approach in the Philippines is simple: if another person must act, have the principal execute a fresh and direct SPA in that person’s favor, or ensure the original SPA expressly grants a power of substitution.

Conclusion

The question of delegation under a Special Power of Attorney is ultimately a question of consent, wording, and trust. The principal chooses the attorney-in-fact for a reason. Because of that, Philippine law does not lightly presume that the chosen representative may hand off the role to someone else.

So, can an attorney-in-fact delegate authority under an SPA?

Yes, but only in limited cases. The default rule is personal performance; delegation is the exception, not the rule. The more important the act, the more clearly the principal’s permission to substitute must appear. In property, banking, and other formal transactions, strict compliance is not just advisable. It is often decisive.
