(B) Any communication between an attorney and a client who is acting as a fiduciary is privileged and protected from disclosure to third parties to whom the fiduciary owes fiduciary duties to the same extent as if the client was not acting as a fiduciary.

(C) As used in this section, "fiduciary" means a trustee under an express trust or an executor or administrator of a decedent's estate.
