A Michigan Affidavit of Service Performed By Lawyer-Guardian Ad Item is a document that is used by lawyers or guardians ad item (Gals) in Michigan to formally acknowledge that they have delivered legal documents to another party. This affidavit, which must be signed by the lawyer or GAL, is typically filed with the court and serves as proof of service. It must contain the date the documents were served, the name of the person served, a description of the documents served, the manner of service, and the signature of the lawyer or GAL. There are two types of Michigan Affidavit of Service Performed By Lawyer-Guardian Ad Item: a standard affidavit and an affidavit for service by publication. The standard affidavit is used to prove that legal documents were served to a party in person. The affidavit for service by publication is used to prove that legal documents were served to a party who could not be located or served in person.
