Without the express written authority of a client, no limited agent may disclose to one client any confidential information about the other client unless the disclosure is required by statute or rule or failure to disclose the information would constitute misrepresentation. No cause of action for any person may arise against a limited agent for making any required or permitted disclosure.
A limited agent does not terminate the limited agency relationship by making any required or permitted disclosures.
