Apostille is the verification of the signature and stamp on a document for use in other countries.

An apostille replaces superlegalization in cases defined by international treaties. One such international treaty is the Convention on the Abolition of the Requirement of Authentication of Foreign Public Documents from 5 October 1961. A document does not have to be verified by the Czech embassy abroad, but the final verification is carried out in the country where the document was issued by the so-called apostille authority.

Every official document issued in Australia and New Zealand, if it is to be used in the Czech Republic, must be officially verified (so-called Apostille) in Australia by the Department of Foreign Affairs and Trade in the country where the relevant document was issued, or by the Department of Internal Affairs in New Zealand. In New Zealand, apply there for the signature and stamp of the registrar, i.e. the Registrar or Deputy Registrar to be certified by way of an apostille.

In the Czech Republic:
- issued by the Ministry of Foreign Affairs of the Czech Republic; or
- by the Ministry of Justice of the Czech Republic (documents issued by judicial authorities or notaries).
