In order to verify a user’s identity, certain states require a notarized sworn letter. If you were born in one of the states that carry this requirement, an additional document with notarization instructions will be provided.
If a notarized sworn letter is required, you are responsible for the notarization of the sworn letter in order to get the application approved by your state. The post-purchase discovery that your state requires notarization does not provide reasonable grounds for a refund.
