For what reason can a broker's personal business funds be placed in the trust he maintains?

A broker's personal business funds should not be placed in the trust he maintains for any reason. The trust fund is meant to solely hold funds on behalf of clients and any misuse of the trust, including using it for personal expenses or lending money to clients, would be considered a violation of fiduciary duty. Investing in real estate would also be considered a misuse of the trust fund. Therefore, the only correct reason for a broker to place personal business funds in the trust would be to pay for service charges and fees associated with maintaining the trust fund.
