What is the maximum amount of a firm's personal funds that may be kept in a trust account to cover service charges?

The correct choice indicates that a maximum of $300 in a firm's personal funds may be kept in a trust account to cover service charges. This regulation helps maintain the integrity of the trust account, ensuring that the funds belonging to clients are strictly separate from those of the firm.

By allowing a specified maximum amount for service charges, it provides a clear guideline for brokers and firms to manage their accounts responsibly while minimizing the risk of co-mingling client funds with personal or business funds. This practice protects clients' money and ensures compliance with legal and ethical standards in real estate transactions.

Understanding this limit is crucial for brokers to avoid any violations related to trust account management. It's important for firms to regularly monitor and manage their accounts to ensure they remain within this set limit, thereby safeguarding client interests effectively.
