The Minnesota Affidavit of Service By Mail is a legal document used to prove that a person was served with legal documents via mail. This document is usually used in civil court cases in the state of Minnesota. It is not required in all cases but is sometimes requested by a court. There are two types of Minnesota Affidavit of Service By Mail: the Standard Affidavit of Service By Mail and the Certificate of Service By Mail. The Standard Affidavit of Service By Mail is a sworn statement that must be signed by the person who served the papers. It must include the name of the person receiving the papers, the date of mailing, the number of copies sent, the name of the sender, and the address of the sender. The affidavit must also be notarized. The Certificate of Service By Mail is a less formal document that does not require a notarized signature. It includes the same information as the Standard Affidavit of Service By Mail but does not require a signature. Both forms of Minnesota Affidavit of Service By Mail must be filed with the court in order to be valid. They can be submitted either in person or by mail.
