Which term refers to the fact that the therapist cannot disclose private communications to any third party unless mandated or permitted by law to do so?

The correct answer is: Confidentiality.

Explanation:

Private Communication can be defined as such a communication between two people or parties, where the discussion, consultation, information sharing, decision taking and documentation conducted in between them is kept confined to both the parties and is never revealed to the public or any third party unless permitted by law. The property of maintaining the secrecy of the details of any communication in between two interacting parties is known as Confidentiality. A confidential report can be shared to a third party by either of the two parties involved in generating the report if and only if the law permits or give its mandate to do so.
