A broker received a birthday check from a client. The broker decided to put it in the escrow account because it was from a client. This is:

Conversion refers to the unauthorized use of a client's funds for personal gain or purposes. While the broker's action can be seen as improper, it does not fit the definition of conversion, which implies taking ownership or control of the funds in a manner that deprives the client of their rights. The situation described does not indicate that the broker is using the funds for personal benefit.

Even if the check were drawn from the client's business account, the action of placing a personal birthday gift check into the escrow account remains inappropriate. Commingling is still a concern regardless of the source of the funds, as it violates regulations related to maintaining separate accounts for personal and client funds.

The time since the client's last transaction does not justify the broker's decision to deposit the birthday check into the escrow account. Commingling laws apply irrespective of transaction history, and this action still represents a mixture of funds that should be kept separate to protect both the client and the integrity of the escrow account.
