Question: Pursuant to Rule 4-1.6(b)(3), may Attorney disclose information related to Attorney’s representation of Former Client without Former Client’s consent, where disclosure is necessary to establish proof of a claim on behalf of Attorney in an action by Attorney against Former Client?
Answer: Rule 4-1.6(b)(3) permits limited disclosure of information otherwise protected by Rule 4-1.6 to the extent necessary to establish a claim, but only where disclosure adverse to the client’s interest is no greater than necessary to accomplish the purpose and the disclosure is made with appropriate safeguards, as described in Comment [12] to Rule 4-1.6.
