WHAT IS AN APOSTILLE?
An apostille is a certification issued by the California Secretary of State that authenticates the signature and seal on a public document for use in another country that is a member of the Hague Apostille Convention.
If the destination country is not a Hague member, the document must go through an authentication and legalization process instead.
