Definition: Apostille in Bible refers to a document or certificate that was not properly signed or stamped by someone other than its original author, thus making it an authentic representation but without being official. It's a practice used for tax documents and government records. Detailled definition: Apostille is the process of stamping an official document with a seal made by the same person as the one who originally authorized the document. This process serves to authenticate the authenticity of a document and prevents forgery attempts.
