In this section, “fiduciary” includes an agent, as defined in § 17–101 of this article. Unless waived by the client, a communication between an attorney and a client that acts as a fiduciary is subject to the attorney–client privilege even if fiduciary funds are used to compensate the attorney for legal services rendered to the client. The existence of a fiduciary relationship between a fiduciary and a beneficiary does not constitute or give rise to a waiver of the attorney–client privilege for communications between the attorney and the fiduciary.
