Wisconsin Waiver of Service of Summons is a legal document that is filed with the court in order to waive a party's right to be served with a summons. It is used in civil cases in Wisconsin, and is most often used when a party to the lawsuit is willing to accept service of the summons from the court instead of having it personally served. There are two types of Wisconsin Waiver of Service of Summons: voluntary and involuntary. A voluntary waiver is when a party agrees to waive their right to be served with a summons. An involuntary waiver is when a party does not agree to waive their right to be served with a summons, but the court still grants the waiver due to the party's inability to be located or served.
