Appropriate service of process is one of the necessary elements for personal jurisdiction—meaning the documents used to initiate a civil lawsuit, a summons and complaint, must be served on the defendant in a manner that allows the court to exercise authority over her. Any judgment entered without service of process is void unless a defendant makes a general appearance in a case or otherwise waives objection to the lack of appropriate service. For that reason, issues with service of process can result in a judgment being set aside.
