There are a few common reasons that a document will not be authenticated:
Insufficient Fees - The authentication fee is $5 per document to be authenticated.
Must be an original signature on the document - All documents must be properly signed by a person representing the agency issuing the document and are required to be an original signature NOT a photocopied signature.
Valid Minnesota Notary Commission - The commission must be valid and up to date and the expiration date on the notary stamp must be accurate. Name on Notary stamp must match Notary database. To determine if the Notary is active and how their name is registered search the notary database.
Country Required - Each document or the cover letter must identify the country of intended use so the correct authentication is attached to the document.
