Apostille (simplified legalization) is used to legalize documents issued and used by member states of the Hague Convention of October 5, 1961.

As a rule, the apostille is used for:

- documents emanating from a body or an official subject to the jurisdiction of the state, including court documents;
- administrative documents;
- notarial deeds;
- official marks such as registration marks; visas confirming a specific date; certification of a signature on a document not certified by a notary;
- documents on civil status: birth certificate, marriage certificate, divorce certificate, death certificate, adoption certificate, etc., and also for certificates from the civil registration authorities. Provided at the place of issue of the document;
- documents on education: diplomas with attachments, certificates with attachments, etc.;
- documents issued by ministries and their subordinate bodies, including the relevant judicial authorities, as well as for copies of documents attested in a notary order.

Apostille is affixed both on the true copies of official documents and on notarized copies.

Apostille is not placed on:

- documents issued by diplomatic or consular agents (legalization is not required);
- administrative documents directly related to a commercial or customs operation (requires legalization through the CCI).
