An "Apostille" is a form of authentication issued to documents such as birth certificates for use in countries that participate in the Hague Convention of 1961. Apostilles authenticate the seals and signatures of officials on public documents. The fee is collected as a partial payment and calculated as Notary state fee + travel + SNI service fee = Total Notary Fee. This fee is subject to increase based on your state. Any difference will be charged accordingly upon the completion of the service.
