Final answer:
For intermediary brokerage scenarios in real estate, written consent is typically required from both the buyer and seller option (A) to acknowledge the dual representation, promote transparency, and protect the parties' interests.
Step-by-step explanation:
In the context of real estate transactions, an intermediary brokerage refers to a brokerage firm that acts as a mediator between a buyer and seller, rather than representing one party exclusively. When an intermediary brokerage situation arises, written consent is generally required to ensure that all parties acknowledge and accept the arrangement where the brokerage represents both the buyer and the seller in a transaction. Therefore, the correct answer to the question of which parties must provide written consent to an intermediary brokerage is A. Both the buyer and seller.
This requirement is put in place to guarantee transparency in the transaction and to ensure that both parties are fully informed about the nature of the intermediary's role and any potential conflicts of interest that may occur. It is also essential because it protects the legal rights and interests of both the buyer and the seller, ensuring that the intermediary brokerage can facilitate the transaction while maintaining a fair and balanced approach.
