Which duty regarding remuneration is imposed by the law of agency on an agent?

In the context of the law of agency, one of the fundamental duties imposed on an agent is the responsibility to be accountable to their principal for their earnings. This means that any commissions or earnings that the agent receives from their activities performed on behalf of the principal must be disclosed and reported back to the principal. The agent has a fiduciary duty to act in the best interests of the principal, which includes managing the principal's resources and funds honestly and transparently.

This accountability ensures that the principal can trust the agent to operate without any hidden manipulations of earnings that could undermine the principal’s interests. The relationship is based on trust, and the obligation to account for any earnings reflects the agent’s duty to maintain that trust and act with integrity.

In contrast, the other options do not accurately represent the legal obligations placed on agents. For instance, receiving commissions in advance is not a standard requirement; transparency about expenses may be important, but the legal obligation leans more towards accountability for earnings especially concerning commissions received; and sharing profits with the principal is not a legal requirement unless explicitly outlined in their agreement.
