What must brokers do regarding commissions in their dealings with clients?

Brokers have a responsibility to maintain transparency with clients concerning commission structures. By notifying clients of commission rates and the way they are calculated in a clear and understandable manner, brokers ensure that clients can make informed decisions about their financial transactions. This practice also fosters trust between brokers and clients, as it demonstrates a commitment to ethical standards and consumer awareness in the real estate industry.

While confidentiality might be expected concerning specific negotiation points, the overarching requirement is to ensure clients understand the costs involved in any dealings. Therefore, clear communication regarding commissions is vital for any financial service provider, and it is a just requirement under best practices and regulations in the industry.

The other options do not align with the ethical standards required in brokerage dealings. Keeping commission rates confidential would impede transparency, limiting clients' ability to make informed decisions. Discussing commissions only upon client inquiry lacks the proactive approach needed to ensure clients fully understand the financial implications of their transactions. Additionally, charging clients without disclosing commission structures goes against the principles of honesty and full disclosure, which are essential for a fiduciary relationship with clients.
