Legalisation formally confirms either the compatibility of the document with the law of the state of its issuance or the authenticity of the signatures and seals on the document.
International documents concerning education background - final high school transcripts and undergraduate or graduate diplomas from international higher education institutions obtained outside Poland must be apostilled or legalised. Otherwise they cannot be taken into account during the enrolment procedure.
The only exemptions to the above requirements include the International Baccalaureate diploma and the European Baccalaureate diploma.
Apostille is, simply put, a confirmation that the certificate/diploma you hold is genuine and can be used abroad. The special clause, issued either as a seal on the document or a separate document, can be obtained in the state issuing the document.
If the state which issued your document is a party to the Convention Abolishing the Requirement of Legalisation for Foreign Official Documents, drawn up in The Hague on 5 October 1961 (Journal of Laws of 2005 No. 112, item 938), find out where to apply for the apostille.
If the state issuing the document is not a party to the Hague Convention, then legalisation is performed by a consulate of the Republic of Poland in this state. You must contact the relevant diplomatic representative and inquire about the process.
