S.D. Codified Laws § 20-1-5
Current with legislation signed by the governor on or before 3/6/2024
An obligation imposed upon several persons, or a right created in favor of several persons, is presumed to be joint, and not several, except in the special cases mentioned in §§ 53-2-4 and 53-2-5. This presumption, in the case of a right, can be overcome only by express words to the contrary.
