When does the fiduciary authority of an agent to their client typically terminate?

The fiduciary authority of an agent to their client typically terminates when the transaction is completed. This is because the fiduciary relationship is fundamentally tied to the specific task of facilitating the transaction, such as buying or selling a property. Once that transaction is concluded, the agent's responsibility to represent the interests of their client in that specific context also comes to an end.

This termination occurs as the primary purpose of the agency—acting on behalf of the client to finalize the transaction—has been fulfilled. While it is possible for a fiduciary relationship to be dissolved in other contexts, such as if either party decides to end it or after a set period of time, the most direct and common point of termination in real estate transactions is upon the completion of the transaction. This ensures that the responsibilities and duties of the agent are closely aligned with the interests and needs of the client throughout the process.
