Michigan Proof of Service is a legal document that serves as evidence that a legal document (such as a petition or summons) was delivered to an individual or organization in accordance with Michigan court rules. There are two types of Michigan Proof of Service: personal service and alternate service. Personal service involves delivering the legal document directly to the person to whom it is addressed, usually in person. Alternate service involves delivering the legal document to an individual or organization other than the person to whom it is addressed, such as via mail, email, or fax. In both cases, the Proof of Service must be signed by the individual who delivered the document and must include the date, time, and method of service.
