The North Dakota Certificate of Endorsement (COE) is a document issued by the North Dakota Secretary of State. It is used to provide legal recognition of a document's authenticity and validity. The COE certifies that the document was legally executed in the state of North Dakota, and it is typically used for documents related to business transactions or legal proceedings. There are two types of North Dakota COE: a Notary Certificate of Endorsement and an Apostle Certificate of Endorsement. The Notary Certificate of Endorsement is used to certify that a document was originally signed and notarized in the state of North Dakota. The Apostle Certificate of Endorsement is used to certify that a document has been authenticated by the Secretary of State's Office, and it is typically used for documents that will be used in a foreign jurisdiction. Both types of COE are issued by the Secretary of State's Office and are used to prove the document's authenticity and validity.
