The Missouri Notice of a Lawsuit and Request to Waive Service of a Summons is a document used to inform a defendant that they are being sued in a civil case and that they must waive service of a summons in order to participate in the case. This notice is typically served to the defendant before the summons is issued in order to give them an opportunity to waive the service and avoid the cost of serving the summons. There are two main types of Missouri Notice of a Lawsuit and Request to Waive Service of a Summons. The first type is the Notice of Filing and Request to Waive Service of Summons, which is used when filing a new case. This document informs the defendant that a lawsuit has been filed against them and requests that they waive service of the summons in order to move forward with the case. The second type is the Notice of Change of Venue and Request to Waive Service of Summons, which is used when a case is being moved from one court to another. This document informs the defendant that the case is being moved and again requests that they waive service of the summons.
