Final answer:
In a real estate corporation, the broker and salespersons are generally required to be licensed. Licensing is based on activities performed, with sales activities necessitating a license. The admin assistant usually does not need a license unless they engage in sales activities.
Step-by-step explanation:
In the scenario where a broker, 3 salespersons and an admin assistant are forming a real estate corporation, licensing requirements can vary depending on the state or country's real estate laws.
Typically, the broker will certainly need to be licensed as they are responsible for overseeing real estate transactions and ensuring legal compliance. Salespersons who engage in activities that include listing, selling, or leasing properties on behalf of the broker also need to be licensed. However, an administrative assistant who performs clerical duties and does not conduct sales activities may not require a license.
