Which of the following activities is an unlicensed real estate assistant in Hawaii prohibited from performing?

Unlicensed real estate assistants in Hawaii are specifically prohibited from explaining legal documents to prospective buyers because this activity requires a certain level of legal knowledge and expertise that an unlicensed individual does not possess. Providing explanations of legal documents involves interpreting the meaning, implications, and legal standing of those documents, which can influence a buyer's decisions significantly. In Hawaii, as in many states, only licensed real estate professionals are qualified to offer guidance and interpretations of legal agreements, contracts, or forms related to real estate transactions.

On the other hand, computing commission checks, preparing promotional materials, and assembling documents for closing are tasks that do not require a real estate license and are, therefore, permissible for unlicensed assistants. These activities are more administrative in nature and do not involve engaging with clients in a manner that would constitute a real estate service, such as providing legal advice or negotiating terms. This distinction is crucial for maintaining the integrity of real estate transactions and protecting consumers from unqualified individuals offering advice or guidance in legal matters.
