S.D. Codified Laws § 22-29-9.1
Any person who submits any petition, application, information, or other document for the purpose of obtaining benefits or any other privilege from the State of South Dakota shall verify, under oath, that such petition, application, or information is true and correct. However, it is sufficient if the claimant, in lieu of verification under oath, signs a statement printed or written thereon in the form following: "I declare and affirm under the penalties of perjury that this claim (petition, application, information) has been examined by me, and to the best of my knowledge and belief, is in all things true and correct." Any person who signs such statement as provided for in this section, knowing the statement to be false or untrue, in whole or in part, is guilty of perjury.
