Michigan Proof of Service is a legal document used to prove that a party has been properly notified of a legal proceeding in the state of Michigan. The document is signed by the person delivering the notice, and it contains information such as the date and time the notice was served, the address where it was served, the name of the person served, and the manner in which it was served. There are three types of Michigan Proof of Service: Personal Service, Certified Mail Service, and Publication Service. Personal Service is the delivery of the notice directly to the person to be served, either by the individual filing the notice or a third-party process server. Certified Mail Service involves sending the notice by certified mail with a return receipt requested. Publication Service requires that the notice be published in a local newspaper in the county where the person to be served lives or works.
