SDCL § 55-4-59: Attorney-client relationship with fiduciary--Duties to other interested persons.

Unless expressly provided otherwise in a written agreement, the creation of an attorney-client relationship between an attorney and a person serving as a fiduciary does not impose upon the attorney any duties or obligations to other persons interested in the estate, trust estate, or other fiduciary property, 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.
