Final answer:
States have imposed strict requirements of explicit disclosures and written consent concerning whom a broker or salesperson represents to address concerns about dual agency.

Driven by concern about dual agency, states have imposed strict requirements of explicit disclosures and written consent concerning whom a broker or salesperson represents. These requirements are in place to ensure transparency and protect the interests of both buyers and sellers in the real estate market. For example, a broker must disclose if they represent both the buyer and seller in a transaction, as this could lead to a conflict of interest.
