An attorney is required to keep all matters confidential regarding his client and may not report a client to authorities except in very limited circumstances that would not apply in your situation. The duty of confidentiality does not end just because the attorney is not representing the client any longer.
Assuming that the information known by the attorney was intended to be confidential and privileged, not only would the attorney be obligated to maintain confidentiality, but that information - and any evidence that may flow from that information - would not be admissible in a judicial or administrative proceeding.
Further, if the attorney takes the kind of action that you ask about, that attorney could be subject to discipline by the California State , up to and including risking his or her license to practice law.
