Which of the following actions is prohibited for an insurance agent under fiduciary duty?

Utilizing client funds for personal expenses is a clear violation of an insurance agent's fiduciary duty. Fiduciary duty requires agents to act with loyalty and care in handling their clients' interests and funds. This entails managing client funds responsibly and solely for the purpose intended, such as processing payments for premiums or holding funds in trust until they are to be remitted to the insurer.

When an agent uses client funds for personal expenses, it undermines the trust inherent in the fiduciary relationship. This action not only jeopardizes the financial security of the client but also contradicts the ethical standards expected within the insurance industry. Maintaining the integrity of fiduciary duty is fundamental to the agent-client relationship, ensuring that clients' best interests are always prioritized and protected.
