S.D. Codified Laws § 15-3-19
Whenever any notice required by law to be served in any judicial or other proceeding authorized by law affecting the title to any real property in this state upon any person having or claiming to have any title to, interest in, or lien upon such real property heretofore has been or hereafter shall be personally served upon such person either within this state or elsewhere, and proof of such service made and filed, notwithstanding such notice may have been or may be defective in form, if it described or shall describe the real property intended to be affected with sufficient certainty to inform the person so served of the tract intended, and to enable a person of ordinary intelligence to understand the object and effect of the notice, no objection to the sufficiency or form of the notice, or to the form of proof of service shall be considered in any action or proceeding involving the title to the real property affected thereby unless the objection be properly made and advantage sought to be taken of it within three years from the personal service of the same. Nothing herein contained shall operate to extend the time for doing any of the acts herein mentioned where the failure to make such objection would, independently of this section, create an estoppel to such objection. Any person under disability at the time of the service of such notice may make objection to the regularity or sufficiency of the same at any time within three years from the removal of the disability.
