The Utah Certificate of Service is a document that is used to prove that service of process was completed in accordance with the Utah Rules of Civil Procedure. It is a signed affidavit that contains specific information about the service of process, such as the name of the person served, the address of the person served, the date of service, the manner of service, and the name of the individual who served the documents. There are two types of Utah Certificates of Service: an original certificate and an amended certificate. The original certificate is issued by an individual who has completed the service of process, while the amended certificate is issued when a party changes the information on the original certificate. Both certificates must be signed and notarized before they can be used in court.
