👉 The term "apostille" refers to a legal document that is notarized and attested by an official witness, typically a notary public or government authority. It's a form of proof of authenticity or conformity to a specific standard or requirement. The apostille process involves the addition of an additional signature or seal at the end of the original document, usually in order to ensure its authenticity. This is done as a precaution against forgery and for legal purposes.
