A Missouri Notice of Intent to Use Process Server is a document filed in the Circuit Court of the county in which the defendant resides, or, if the defendant is not a resident of Missouri, the county in which the action is pending. The notice is used to inform the defendant that the plaintiff intends to serve process (i.e. legal documents such as summons, writs, complaints, and subpoenas) by a process server. The notice must include the name of the plaintiff, the name of the defendant, the case number, and the address and telephone number of the process server. There are two types of Missouri Notice of Intent to Use Process Server: a Regular Notice of Intent and a Voluntary Notice of Intent. A Regular Notice of Intent is used when the defendant has not yet been served with process. The Voluntary Notice of Intent is used when the defendant has already been served with process, but the plaintiff wishes to serve additional documents.
