The disclosure of confidential information to a third party is unethical unless which of the following occurs?

The correct answer is that the disclosure of confidential information to a third party is considered ethical when it is authorized by the client. In the realm of professional appraisals, confidentiality is a fundamental principle that appraisers are expected to adhere to. This principle protects the privacy and interests of clients, ensuring that sensitive information is not shared without consent.

When a client provides explicit authorization for the disclosure of their confidential information, it allows the appraiser to ethically share that information with specified third parties. This consent can include various forms, such as verbal agreements or written documents, indicating the client's approval, thus fulfilling the appraiser's obligation to protect confidential information while still respecting the client's wishes.

The other choices do not inherently meet the ethical standards regarding confidentiality. Documenting the disclosure in the appraisal report does not suffice if the client has not authorized it. Approval from a regulatory agency does not replace the need for client consent. Presenting information in a public forum, regardless of the context, would violate confidentiality unless the client explicitly approves of such a broad disclosure. Hence, client authorization remains the crucial factor for ethical disclosure of any confidential appraiser-client information.
