In Philippine law, a Special Power of Attorney (SPA) is a legal instrument whereby a person (the Principal) authorizes another person (the Agent or Attorney-in-Fact) to perform specific acts or transactions on their behalf. Unlike a General Power of Attorney, which grants broad administrative powers, an SPA is restricted to specific, defined tasks.

The governing law for SPAs is found primarily in Articles 1874 to 1880 of the Civil Code of the Philippines.

When is an SPA Mandated by Law?

Under Article 1878 of the Civil Code, an SPA is strictly required for the following acts:

To make payments that are not considered 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 (real estate) is transmitted or acquired.
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 (e.g., mortgaging a house).
To accept or repudiate an inheritance.
To ratify obligations contracted before the agency.
Any other act of strict dominion.

Essential Requirements for Validity

For an SPA to be legally binding and enforceable against third parties (such as banks, the Register of Deeds, or courts), it must meet several criteria:

1. Legal Capacity

Both the Principal and the Agent must have the legal capacity to act. The Principal must be of legal age (18+) and of sound mind.

2. Specificity of Powers

The document must clearly describe the acts the Agent is authorized to perform. Philippine courts strictly construe SPAs; if a power is not explicitly stated or "necessarily implied" from the stated power, the Agent cannot perform it.

3. Written Form for Real Estate

Under Article 1874, when a sale of a piece of land or any interest therein is through an agent, the authority of the latter must be in writing; otherwise, the sale is void.

4. Notarization

While an unnotarized SPA may be valid between the Principal and Agent, it must be notarized to become a public document. Notarization is required for the SPA to be registered with government agencies (like the Bureau of Internal Revenue or the Land Registration Authority) and to be admissible in court without further proof of its authenticity.

5. Consularization (For Principals Abroad)

If the Principal is outside the Philippines, the SPA must be executed at the Philippine Embassy or Consulate in that country (Consularization) or, for Hague Convention member countries, it must bear an Apostille certificate.

Standard Format of an SPA

While the language can vary, a standard Philippine SPA follows this structural flow:

Title: "SPECIAL POWER OF ATTORNEY" (centered).
Preamble: Identifies the Principal (Name, nationality, marital status, and residence).
Appointment: Clearly states: "I do hereby name, constitute, and appoint [Agent's Name] to be my true and lawful attorney-in-fact..."
Grant of Powers: A numbered list of the specific acts authorized (e.g., "To sell a parcel of land covered by TCT No. 12345...").
General Clause: A standard "Substitutionary Clause" allowing the agent to do all things necessary to carry out the specific powers granted.
Acceptance/Signature: The Principal signs the document. The Agent may also sign to show acceptance, though it is not always strictly required for validity.
Witnesses: At least two witnesses must sign the document.
Acknowledgment: The Notary Public's section, where the Principal personally appears and presents a valid government-issued ID to verify their identity.

Extinguishment of an SPA

An SPA does not last forever. Under Article 1919, it is extinguished by:

Revocation by the Principal.
Withdrawal of the Agent.
Death, civil interdiction, insanity, or insolvency of the Principal or the Agent.
Dissolution of the firm or corporation which entrusted or accepted the agency.
Accomplishment of the object or purpose of the agency.
Expiration of the period for which the agency was constituted.

Important Note: If the Principal dies, the SPA is generally terminated by operation of law. Any action taken by the Agent after the Principal's death is void, unless the Agent acted in good faith without knowledge of the death or if the agency was constituted for the common interest of the Principal and the Agent (Agency Coupled with an Interest).
