A Nevada Certificate of Service is a document used to prove that legal documents have been properly served to a defendant in a legal action. It is typically completed by a process server or other person authorized to serve documents on behalf of a court. It is used to prove to the court that the defendant was properly served with the documents in question. There are two types of Nevada Certificate of Service: the original certificate, which is completed and sworn to by the server, and a duplicate certificate, which is signed by the court clerk and used as proof of service in court. The original certificate must include the date, time, and location of service, a description of the documents served, and the name and address of the person served. The duplicate certificate must include the same information, as well as a statement that the original certificate was sworn to and filed with the court.
