Which duty is MOST difficult for a dual agent to fulfill fairly?

Obedience involves following the specific instructions given by clients. While it may present challenges in conflicting situations, it primarily hinges on adhering to client commands rather than making subjective decisions about interests. Therefore, it is less difficult in the context of dual agency, as the agent can still follow orders without compromising loyalty.

Accounting refers to the duty of accurately managing and reporting financial transactions. While it requires meticulous attention to detail, it is largely objective and can be performed without bias toward either party. Thus, it does not involve the subjective complexities that loyalty entails, making it a more manageable responsibility in dual agency.

Disclosure involves informing clients of relevant information that may impact their decisions. While it can be challenging, particularly regarding what to disclose to whom, it is typically a more straightforward obligation than loyalty. An agent can disclose information without necessarily favoring one party over the other, which makes it less difficult in a dual agency scenario.
