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 (the complaint) (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 Iowa, as in all 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 fairly notified of legal actions against one's interests, allowing the defendant the opportunity to appear in court and defend against the lawsuit. Additionally, proper service of process is necessary to establish personal jurisdiction, which gives the court the authority to make decisions affecting the defendant. In Iowa, the rules for service of process are outlined in the Iowa Rules of Civil Procedure. Service can be accomplished through various means, including personal service, where the documents are handed directly to the defendant, or by other methods such as service by publication if the defendant cannot be located. Failure to properly serve a defendant can result in delays or dismissal of the lawsuit.
