A broker receives a buyer ' s earnest-money check and places it promptly into the...

The correct answer is B, Commingling. Commingling means improperly mixing money belonging to clients or transaction parties with the broker ' s own personal or business funds.

Massachusetts Board guidance explains that escrow accounts are specifically used for earnest-money deposits and other qualifying transaction funds. Only appropriately licensed brokers may maintain such accounts, and salespersons are prohibited from independently holding client funds.

The broker has no personal claim to escrow money simply because the broker possesses it. The funds must be maintained and distributed according to the transaction, applicable contracts, and Massachusetts regulations.

Candidates should distinguish commingling from conversion. Commingling is the improper mixing of funds. Conversion occurs when the broker actually appropriates or uses client money for unauthorized purposes.

Steering and blockbusting are fair-housing violations, not escrow violations.
