What does the duty of confidentiality require of a real estate agent?

The duty of confidentiality requires an agent to protect all private information that could weaken their client's negotiating position, such as the seller's willingness to accept a lower price, the buyer's maximum budget, financial difficulties, personal circumstances motivating the sale, or any other information the client has not authorized for disclosure. This duty survives the termination of the agency relationship, meaning the agent must keep confidential information private even after the transaction closes.
