For a Norwegian document to be considered valid in Greece, it must be issued with an apostille stamp.

The Apostille-stamp confirms the validity of a public official’s signature. The County Governor - Statsforvalteren is the responsible authority in Norway. 

For information on apostille on Greek documents, please visit website of the Ministry of Interior and the website of HCCH.

The Hague Convention makes it possible for official documents from one of the countries that has joined the convention to become valid in one of the other countries that has joined the convention, by the application of an Apostille-stamp. Both Norway and Greece have joined the convention.
