SDCL § 21-22-19: Publication of notice in lieu of personal service.

When the number of persons to be served is large and the expense of service provided by § 21-22-18 would be burdensome, the court may, if it deems advisable, order, in lieu of service as provided in § 21-22-18, that such notice be published once each week for three successive weeks in a legal newspaper of the county prior to such hearing.
