In accordance with the Hague Convention of October 5, 1961, in which both the Russian Federation and State of Israel are participants, documents authenticated by an Apostille of a participant country are exempted from validation (i.e., from verification of the authenticity of the signatures, the authority of the persons signing, and the authenticity of the seals and stamps) by the consular establishments of other participant countries. Documents with Apostille do not require any further legalization. 

The Apostille is a stamp established by the Hague Convention, placed in documents by a competent authority of the country in which the document was issued.
