Who must sign the agency form to establish a relationship?

The correct choice is the licensee and the client because establishing an agency relationship in real estate requires a mutual agreement between the parties involved. The licensee, who represents the real estate agency, must obtain written consent from the client to formalize this relationship. This ensures that both the licensee and the client understand the nature of their relationship, including the rights and responsibilities of both parties.

In real estate transactions, the agency form serves as a legal document that outlines these terms, protecting the interests of both the client and the licensee. This agreement is critical in establishing trust and clarity about the services provided and the obligations carried out by the licensee on behalf of the client.

Other choices may involve parties that do not fulfill the essential legal requirements needed to establish an agency relationship. For example, while a broker and client or a licensee and their supervisor may have important roles in the transaction, they are not the parties who directly form the agency relationship. The direct interaction and agreement between the licensee and the client are what truly underpin the establishment of agency in a real estate context.
