When Can an Agent Delegate Authority? The Rule on Substitution Under Philippine Law

Philippine law presumes an agent may appoint a substitute unless prohibited. Learn the rules, limits, and risks from a Supreme Court ruling.


The Civil Code creates a default rule that may surprise many principals: an agent can appoint a substitute unless the principal expressly prohibits it. In Spouses Villaluz v. Land Bank of the Philippines (G.R. No. 192602, January 18, 2017), the Supreme Court applied this rule and clarified its limits, including when a mortgage secured by a substitute agent binds the principal.

The Facts of the Case

In 1996, Paula Agbisit asked her daughter, May Villaluz, to provide collateral for a business loan. May and her husband Johnny executed a Special Power of Attorney (SPA) in favor of Agbisit, authorizing her to negotiate for the sale or mortgage of their land in Davao City. The SPA did not prohibit Agbisit from appointing a substitute.

Agbisit then executed her own SPA, appointing Milflores Cooperative — where she served as chairperson — as attorney-in-fact to obtain a loan from Land Bank and execute a real estate mortgage over the Villaluz property. Milflores Cooperative executed the mortgage in favor of Land Bank for a P3,000,000 loan. When the cooperative defaulted, Land Bank foreclosed on the property. The Villaluz spouses sued to annul the foreclosure.

The Issue: Validity of the Substitute's Acts

The central question was whether Agbisit could validly delegate her authority to Milflores Cooperative, and whether the mortgage executed by the cooperative bound the Villaluz spouses.

Article 1892 of the Civil Code provides the answer. The agent may appoint a substitute if the principal has not prohibited it. The agent becomes responsible for the substitute's acts when the agent was not given the power to appoint one, or when the substitute appointed was notoriously incompetent or insolvent. All acts of a substitute appointed against the principal's prohibition are void.

The Court held that because the SPA contained no prohibition against substitution, Agbisit's appointment of Milflores Cooperative was valid. Upon valid appointment, the substitute becomes the agent of the principal, and the principal is bound by the substitute's acts as if performed by the original agent.

The Mortgage Was Not Void for Lack of Consideration

The Villaluz spouses raised a new theory: the mortgage was void because the loan did not yet exist when the mortgage was executed. They cited Article 1409(3) of the Civil Code, which voids obligations whose cause or object did not exist at the time of the transaction. (Note: the exact statutory text of Article 1409(3) is not reproduced in the library; the description here follows the Court's summary in the decision.)

The Court rejected the spouses' narrow reading. Citing Articles 1347, 1461, and 1462, which allow future things as objects of contracts, the Court adopted the interpretation that the provision refers to objects that could not come into existence. Since Land Bank was capable of granting the loan — and in fact released funds days later — the mortgage's cause was not impossible.

The Court also noted that in loan transactions, lenders routinely require security contracts before releasing funds. The mortgage was conditioned upon the release of the loan, a suspensive condition satisfied when Land Bank released the first tranche.

The Assignment Did Not Extinguish the Loan

The spouses further argued that the Deed of Assignment of Produce/Inventory extinguished the agency because it served as payment. The Court disagreed. The assignment was expressly for the purpose of securing the payment of the loan — it was an accessory obligation, not a dation in payment under Article 1245 of the Civil Code.

Practical Takeaways

  • Read the SPA carefully. If you want to prevent your agent from appointing a substitute, say so explicitly in the power of attorney.
  • A substitute binds the principal. Once validly appointed, the substitute's acts within the scope of authority are binding on you as if you appointed them directly.
  • The remedy is against the agent. If a substitute acts badly, the principal may seek recourse against the agent under Articles 1892 and 1893 of the Civil Code.
  • Future loans can secure present mortgages. A mortgage executed before loan release is valid if the loan is later perfected.
  • Security assignments are not payments. Unless the parties clearly intend otherwise, assigning collateral secures a debt; it does not extinguish it.

The Court reminded litigants that courts will not rescue parties from unwise bargains. The remedy for a principal who feels wronged by a substitute's acts lies in the Civil Code's provisions on agency — not in belated attempts to void otherwise valid transactions.
