The defendant in a lawsuit must be served (delivered) a summons or citation (an order from the court to appear and answer the lawsuit) and a copy of the lawsuit (1) to provide due process (fairness) by giving the defendant notice of the lawsuit and the opportunity to appear in court and defend the lawsuit; and (2) to give the court personal jurisdiction (authority) over the defendant.
In South Dakota, as in other states, the legal process requires that a defendant in a lawsuit must be properly served with a summons or citation and a copy of the complaint initiating the lawsuit. This is to ensure due process, which is the constitutional right to be informed of legal action against oneself and to have a fair opportunity to respond and defend against the lawsuit in court. The service of process must be carried out in a manner prescribed by law, which typically includes personal delivery to the defendant or an authorized agent. Additionally, proper service establishes the court's personal jurisdiction over the defendant, meaning the court has the authority to make decisions regarding the defendant in the case. South Dakota's rules regarding service of process are outlined in the South Dakota Codified Laws (SDCL) and must be followed to ensure that the defendant's due process rights are protected and that the court can exercise jurisdiction over the case.
