The Rule on ‘The Special Power of Attorney’ (SPA) and when it is Required

March 29, 2026

I. Introduction

This memorandum exhaustively examines the rule on the special power of attorney (SPA) under Philippine civil law, delineating its definition, legal basis, distinguishing characteristics from a general power of attorney, and the specific acts for which it is required. The analysis is grounded primarily on the provisions of the Civil Code of the Philippines, pertinent jurisprudence, and established legal commentary. The central rule is that an SPA is strictly necessary for acts of dominion or those which transcend acts of mere administration, as these involve the disposition of the principal’s proprietary rights.

II. Definition and Legal Basis

A power of attorney is an act whereby one person, the principal, confers authority upon another, the agent or attorney-in-fact, to act in the principal’s name and behalf. Article 1878 of the Civil Code explicitly enumerates the acts for which a special power of attorney is mandatory. The SPA is characterized by its limitation to a specific act or transaction, or a set of related acts, as expressly defined within the instrument itself. Its authority is construed strictly against the agent.

III. Distinction: Special Power of Attorney vs. General Power of Attorney

A general power of attorney grants broad authority to perform acts of administration. These are acts necessary for the day-to-day management and preservation of property or rights, such as collecting rents, paying ordinary expenses, or overseeing maintenance. Conversely, a special power of attorney is required for specific, extraordinary acts that go beyond mere administration, particularly those enumerated under Article 1878. The key distinction lies in the scope: general powers cover routine management, while special powers are essential for acts that alter, dispose of, or create real rights over the principal’s property.

IV. When a Special Power of Attorney is Required: Acts of Dominion

The paramount rule is that a special power of attorney is indispensable for acts of dominion. An act of dominion is one which constitutes an exercise of ownership, involving the disposition or conveyance of ownership, or the creation or extinguishment of real rights. The necessity for an SPA is not merely procedural but jurisdictional; an agent acting without the requisite special authority renders the contract not merely voidable, but unenforceable against the principal, unless subsequently ratified.

V. Specific Acts Enumerated under Article 1878 of the Civil Code

Article 1878 provides a non-exhaustive but critical list of acts requiring an SPA:

To make such payments as are not usually considered as acts of administration;

To effect novations which put an end to obligations already in existence at the time the agency was constituted;

To compromise, to submit questions to arbitration, to renounce the right to appeal from a judgment, to waive objections to the venue of an action or to abandon a prescription already acquired;

To waive any obligation gratuitously;

To enter into any contract by which the ownership of an immovable is transmitted or acquired either gratuitously or for a valuable consideration;

To make gifts, except customary ones for charity or those made to employees in the business managed by the agent;

To loan or borrow money, unless the latter act be urgent and indispensable for the preservation of the things which are under administration;

To lease any real property to another person for more than one year;

To bind the principal to render some service without compensation;

To bind the principal in a contract of partnership;

To obligate the principal as a guarantor or surety;

To create or convey real rights over immovable property;

To accept or repudiate an inheritance;

To ratify or recognize obligations contracted before the agency;

Any other act of strict dominion.

VI. Formalities and Execution

While a power of attorney is generally not required to be in a public document for its validity between the parties, Article 1874 of the Civil Code mandates that for the conveyance of real property or any interest therein through an agent, the authority must be in a public document. Similarly, for the agent to enter into a contract where the Statute of Frauds applies (e.g., sale of goods priced at P500.00 or more, agreements not to be performed within one year), the authority of the agent must also be written. Therefore, for most acts requiring an SPA—particularly those involving immovables—execution in a public document (i.e., notarized) is a prerequisite for enforceability and registrability.

VII. Comparative Analysis: General vs. Special Power of Attorney

Aspect	General Power of Attorney	Special Power of Attorney
Governing Concept	Authority for acts of administration	Authority for acts of dominion or specific extraordinary acts
Scope of Authority	Broad and continuing; covers routine management and preservation	Narrow, limited, and specific to the act(s) enumerated in the instrument
Legal Basis	Implied from general grant of authority; Articles 1877 and 1883, Civil Code	Expressly required by Article 1878, Civil Code for listed acts
Interpretation	Interpreted reasonably to accomplish the purpose of general management	Interpreted strictly; authority cannot be implied from a general grant
Common Examples	Collecting income, paying utilities, hiring ordinary staff, routine repairs	Selling land, borrowing money on credit, compromising litigation, creating a mortgage
Formality Requirement	Often a private writing suffices for acts within its scope	For acts covered by Article 1874 (e.g., sale of land), must be in a public document
Effect of Lack of Authority	Agent may bind principal for acts within implied usual authority	Contract is unenforceable against the principal if the specific act required an SPA and none was granted

VIII. Consequences of Acting Without a Required Special Power of Attorney

An agent who performs an act requiring an SPA without such specific authority does not bind the principal. The resulting contract is unenforceable against the principal, pursuant to Article 1874 and Article 1403(1) of the Civil Code (Statute of Frauds). It is as if no contract existed with the principal. However, the principal may subsequently ratify the unauthorized act, thereby curing the defect. The agent, in turn, may be held liable to the third party for damages under the doctrine of implied warranty of authority or for breach of warranty of his authority.

IX. Jurisprudential Application

The Supreme Court has consistently upheld the strict requirement for an SPA. In Litonjua vs. Litonjua, it was held that a general power of attorney did not authorize the agent to sell the principal’s property, as a sale is an act of dominion. In Heirs of Yaptinchay vs. Del Rosario, the Court ruled that a general management agreement did not constitute a special power to mortgage property. Furthermore, in Siasoco vs. Court of Appeals, the Court emphasized that the authority to sell must be express, and the price and conditions of the sale must be specified in the SPA. Jurisprudence treats the absence of a required SPA as a defect affecting the very validity of the agent’s representation for that specific act.

X. Conclusion and Practical Guidance

The rule on the special power of attorney is clear and stringent: it is required for all acts of dominion and for the specific extraordinary acts listed in Article 1878 of the Civil Code. A general power of attorney is insufficient for such purposes. In practice, legal practitioners must:

Scrutinize the intended act of the agent against the list in Article 1878.

Ensure that for any act involving immovable property or falling under the Statute of Frauds, the SPA is executed in a public instrument (notarized).

Draft the SPA with precise language, specifying the property, the act authorized, the price or terms if applicable, and the identity of the parties involved.

Advise clients that any ambiguity in the power will be construed against the agent, and acting without proper authority exposes both the agent and the transaction to significant legal risk.

Failure to secure the requisite SPA renders the agent’s act unenforceable, protecting the principal from unauthorized dispositions of their substantive rights.
