Agency Fundamentals: Single Agency, Broker Authority, and Subagency
In real estate brokerage, understanding representation begins with recognizing the roles of the parties involved. Single agency occurs when an agent represents only one party in a real estate transaction. Under this arrangement, the party represented by a real estate broker through an agency agreement is designated as the client or principal. In a single agency relationship, the agent owes full fiduciary duties exclusively to this one principal. Conversely, an unrepresented party involved in the transaction is known as a customer or third party. While salespersons work day-to-day with consumers, real estate brokerage contracts, such as listing contracts and buyer representation agreements, legally belong to the supervising broker rather than the salesperson. Furthermore, salespersons generally receive compensation for their licensed activities through their supervising broker, subject to state-law exceptions, and sponsoring brokers remain responsible for supervising the licensed activities and agency disclosures of their affiliated salespersons.
Transactions frequently involve more than one brokerage firm. A cooperating broker is a broker from an independent firm who participates in a real estate transaction alongside the listing broker. Historically, cooperating brokers operated under the legal framework of subagency. A subagent is defined as an agent appointed by another agent to perform duties for a principal. Under traditional subagency, a cooperating broker represented the seller rather than the buyer. As a result, the subagent owed the exact same fiduciary duties to the principal as the primary listing agent owed. For example, when an independent broker showed a listed home to a prospective buyer under traditional subagency, that broker was legally acting on behalf of the seller, and the prospective buyer was treated as an unrepresented customer rather than a client.
Because agency creates serious legal obligations, a broker cannot establish a subagency relationship without the knowledge and consent of the seller. Under traditional subagency principles, a seller may be held liable for a subagent's acts that fall within the scope of the agency, while liability for unauthorized acts or misrepresentations depends upon the specific facts and applicable state law. Due to the inherent confusion and potential liability of having cooperating brokers represent sellers against prospective buyers, buyer representation has largely replaced subagency in modern residential real estate practice.
Common mistakes
- Assuming cooperating brokers always represent buyers: Historically, cooperating brokers acted as subagents representing the seller, leaving the buyer unrepresented.
- Believing dual agents cannot disclose property defects: Dual agency restricts disclosing confidential client negotiations (like bottom-line prices), but agents must still disclose known material adverse property facts when required by law.
- Confusing designated agency with dual agency rules: Designated agency allows separate affiliated licensees to offer individual loyalty and confidentiality to opposing clients, whereas a dual agent cannot advocate exclusively for either client.
- Assuming agency duties vanish entirely upon agreement termination: The duty of confidentiality and the broker's duty of accounting generally survive the termination of the agency agreement.
Key points
- Single agency provides representation to one principal; the other party may be an unrepresented customer or may have their own agent.
- Historically, cooperating brokers acted as subagents of the listing broker, owing full fiduciary duties to the seller while treating the buyer as a customer.
- Dual agency involves representing both buyer and seller in the same transaction; it creates an inherent conflict of interest, requires informed consent where legal, and is prohibited by statute in some states.
- Dual agents must protect confidential price limits and motivations, subject to applicable exceptions, and disclose known material adverse property facts when required by law.
- Designated agency allows a supervising broker to assign separate affiliated licensees to individually represent opposing clients with loyalty and confidentiality.
- Transaction brokers facilitate transactions without fiduciary advocacy or undivided loyalty; their duties generally include honesty and fair dealing, along with disclosure of known material adverse facts as required by state law.
- Duties of confidentiality and accounting for funds and property generally survive the termination of an agency relationship.
