In accordance with The Hague Convention on the documents executed by the competent authorities of one country and intended for use on the territory of another state, the special stamp (apostille) is to be put. According to Article 5 of the Convention apostille authenticates the signature, the capacity of the person signing the document, and when appropriate, the identity of the seal or stamp which the document bears.
Stamping “apostil” (sometimes this procedure is also called "simplified legalization" or "Apostille") is used to send a document to the countries that joined the Hague Convention of the 5th October, 1961 Abolishing the Requirement of consular legalization and introducing a simplified procedure of legalization - stamping "apostille. "
Simplified this procedure is called because, on the one hand, the apostille is fast enough and involves the only one authorized body, and, on the other hand, the document becomes valid in all countries that have acceded to the Hague Convention.
If a country you are drawing up a document to is not a member of the Hague Convention, consular legalization is required. This is a more complicated procedure, which includes certification of a document in the bodies of the Ministry of Foreign Affairs of the Republic of Kazakhstan, and then in the consulate of a country of destination in the Republic of Kazakhstan. Thus, a document will have legal force only on the territory of a country whose consulate marks it.
Also the choice of the legalization procedure may be based on the type of document, as there are many documents which are not subject to any consular legalization or apostille. This applies mainly to commercial documents: contracts, invoices, bills of lading, and various documents of title and other documents related to foreign trade activities, and for them there is a separate procedure - legalization of the document in the Chamber of Commerce of the Republic of Kazakhstan (most recently part of the National Economic Chamber Kazakhstan "Atameken"), and then at the consulate of the destination country.
