SDCL § 55-4-60: Attorney-client relationship with fiduciary--Privileged communications--Relation to beneficiary.

If an attorney-client relationship exists between an attorney and a fiduciary, communications between the attorney and the fiduciary are subject to the attorney-client privilege, unless waived by the fiduciary, even though fiduciary moneys may be used to compensate the attorney for legal services rendered to the fiduciary, or even if a beneficiary is entitled to accountings or other information regarding the estate, trust estate, or fiduciary property. The existence of a fiduciary relationship between a fiduciary and a beneficiary does not constitute or give rise to any waiver of the privilege for communications between the attorney and the fiduciary.
