In which situation can a real estate broker legally represent more than one client?

A real estate broker can legally represent more than one client in a situation where both clients agree in writing. This is crucial because the written agreement serves to ensure that all parties are aware of and consent to the dual agency relationship. It provides a clear disclosure of the broker's role and responsibilities to both clients, helping to prevent conflicts of interest. Without this agreement, the broker may encounter ethical and legal issues, as representing multiple clients without their consent can lead to compromised fiduciary duties.

In contrast, working on multiple transactions does not automatically imply that a broker can represent multiple clients simultaneously unless there is explicit consent. The belief of a broker that they can manage both clients does not replace the need for informed consent. Similarly, representing competing buyers can lead to significant conflicts of interest, which is why written consent is essential for any dual representation scenario. Thus, it is the agreement in writing that solidifies the legality of representing multiple clients.
