Marianne's request for no showings on Sundays is an example of which fiduciary duty?

The request made by Marianne for no showings on Sundays falls under the fiduciary duty of obedience. This duty requires a real estate agent or broker to act in accordance with their client's wishes, as long as those wishes are lawful and do not violate any ethical guidelines.

In this scenario, Marianne is specifying a particular preference regarding showings of her property. By adhering to this request, the agent demonstrates their commitment to following the client's instructions, which is fundamental to building trust and maintaining a professional relationship. Obedience is crucial as it ensures that the agent is representing the best interests of the client by honoring their requests.

While the other duties such as confidentiality, disclosure, and due diligence are also important aspects of a fiduciary relationship, they do not directly address the specific action of complying with a client's preferences, which is the essence of the obedience duty.
