What is the relationship called when a broker represents a seller or buyer under a single agency agreement?

The relationship referred to in the question is known as a single agent relationship. In real estate, a single agency agreement establishes a fiduciary relationship where the broker represents only one party in a transaction, either the seller or the buyer. This means the broker has a legal and ethical obligation to act in the best interests of their client, providing loyalty, confidentiality, and full disclosure among other responsibilities.

In this context, the term "single agent" is vital as it delineates the responsibilities and protections afforded to the client. This type of representation ensures that the client's needs are prioritized without conflicting interests since the broker is not representing both parties in the transaction.

Other types of agency relationships, like transaction agency or dual agency, do not offer the same level of client loyalty and may involve representing more than one party or serving merely as a facilitator. Therefore, the single agent relationship is distinct and emphasizes a commitment to serving one client's interest above all else.
