Q. Do my duties of confidentiality to former clients continue even after I leave my firm?
A. Comment 7 to IRPC 1.9 states that a lawyer changing professional association has a continuing duty to preserve confidentiality of information about a client formerly represented. However, this duty may not preclude a lawyer from using generally known information about that client. (IRPC 1.9, comment ). Comment  to the rule also allows for the provisions of 1.9 to be waived if the client gives informed consent. For a full understanding, please see IRPC 1.9.
