In the Philippine legal landscape, the concept of representation is a cornerstone of commerce. Whether it is a real estate broker closing a sale, a talent manager signing a contract, or a digital platform facilitating a delivery, the relationship is governed by a specific set of rules rooted in the Civil Code of the Philippines and supplemented by modern regulatory frameworks.

I. The Nature of the Contract of Agency

Under Article 1868 of the Civil Code, a contract of agency is defined as a relationship where a person binds himself to render some service or to do something in representation or on behalf of another, with the consent or authority of the latter.

Key Characteristics

Consensual: It is perfected by mere consent.
Principal: It can stand alone without the need for another contract.
Nominate: It has a specific name and set of rules under the law.
Preparatory: It is entered into as a means to execute other juridical acts (e.g., an agent enters into a sale for the principal).
Representative: The agent acts not for themselves, but as an extension of the principal’s personality.

Essential Elements for a Valid Agency

For an agency to legally exist, four elements must be present:

Consent (express or implied) of the parties to establish the relationship.
Object, which is the execution of a juridical act in relation to third persons.
The agent acts as a representative and not for himself.
The agent acts within the scope of his authority.

II. Kinds of Agency and the Scope of Authority

The law distinguishes between how an agency is created and the extent of the power granted.

1. By Manner of Creation

Express: Documented through a written or oral agreement.
Implied: Derived from the acts of the principal, from their silence or lack of action, or their failure to repudiate the agency knowing that another person is acting on their behalf.

2. By Extent of Business

General Agency: Comprises all the business of the principal.
Special Agency: Comprises one or more specific transactions.

3. The Special Power of Attorney (SPA)

Under Article 1878, a Special Power of Attorney is strictly required for specific acts of strict ownership, such as:

To make payments that are not considered acts of administration.
To effect novations.
To compromise, submit questions to arbitration, or renounce the right to appeal.
To waive any obligation gratuitously.
To convey or acquire immovable property (real estate).
To loan or borrow money, unless the latter be urgent and indispensable for the preservation of things under administration.

III. Rights and Obligations of the Parties

Obligations of the Agent

The agent is bound by a fiduciary duty. Their primary responsibilities include:

Carrying out the agency: The agent must finish the business begun on the death of the principal should delay entail any danger.
Advancing instructions: Following the principal’s instructions unless doing so would cause manifest damage to the principal.
Loyalty: An agent cannot acquire by purchase, even at a public or judicial auction, the property whose administration or sale may have been entrusted to them, unless the principal consents.
Accounting: The agent must render an account of their transactions and deliver to the principal whatever they may have received by virtue of the agency.

Obligations of the Principal

Compensation: Unless otherwise stipulated, the agency is presumed to be for a compensation.
Advancing Funds: The principal must advance the sums necessary for the execution of the agency if the agent so requests.
Indemnification: The principal must reimburse the agent for sums advanced and indemnify them for damages incurred in the fulfillment of the agency without the agent's fault.

IV. Third-Party Intermediaries (TPIs) and Modern Regulation

In contemporary Philippine law, "Third-Party Intermediaries" often refer to specialized agents regulated by specific statutes beyond the Civil Code.

1. Real Estate Service Act (RESA) - RA 9646

Real estate brokers and agents are TPIs governed by the Professional Regulation Commission (PRC). They must be licensed to legally represent a principal in real estate transactions. Acting as a TPI in real estate without a license carries criminal penalties.

2. The Internet Transactions Act (ITA) of 2023 - RA 11967

The digital age has introduced a new breed of TPI: the E-marketplace. Platforms like Shopee, Lazada, and Grab act as intermediaries between merchants and consumers.

Liability: Under the ITA, these platforms are generally not liable for the conduct of the merchant unless they fail to exercise due diligence or fail to take down illegal content upon notice.
Consumer Protection: The law treats these platforms as a bridge, imposing obligations to ensure transparent pricing, merchant identity verification, and dispute resolution mechanisms.

3. Insurance Brokers

Insurance intermediaries are governed by the Insurance Code. Unlike an "insurance agent" who represents the company, an "insurance broker" is a TPI that represents the insured party in negotiating insurance contracts.

V. Extinguishment of Agency

The relationship is fragile and can be terminated by any of the following (often remembered by the acronym EDWARD):

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

The Doctrine of "Agency Coupled with an Interest"

A principal cannot generally revoke an agency at will if it is "coupled with an interest." This occurs when the agency is created for the mutual benefit of the principal and the agent, or for the benefit of a third person (e.g., if the agency is a means of fulfilling an obligation already contracted).
