Which action is prohibited for an unlicensed assistant?

An unlicensed assistant is prohibited from conducting activities that require a real estate license. Calling for late payments typically involves negotiating or discussing terms related to financial transactions, which is considered a licensed activity. This role includes interpreting real estate contracts, discussing payment schedules, and potentially influencing a property's financial handling, all of which require a licensed professional to ensure compliance with legal standards and ethical practices.

While an unlicensed assistant may help with marketing tasks or administrative duties as long as they do not engage in negotiations or legal transactions, activities that involve financial discussions or the negotiation of terms fall outside their permissible scope. Therefore, calling for late payments is not allowed for someone who is unlicensed, as it steps into the territory of real estate practice that requires professional credentials.
