Verification of the authenticity of foreign documents

Apostille is a certificate, by which a Notary Public authenticates a document as genuine, thereby legalizing it for use in another member country of the Hague Conference.

Once a document has been Apostillised, thereby providing official authentication of the signatures and stamps appearing on it, it is automatically deemed legalized for use in another member country of The Hague Conference.

It is an intergovernmental organisation whose purpose is to establish a simplified system to allow public documents originating in one member country to be easily recognized as authentic in another member country, under the auspices of the Hague Convention of 5th of October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents. Authorities in Greece need proof that norwegian  documents or the signatures of norwegian officials on documents are genuine before they accept them.

Countries that are parties to the Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents (Greece and Norway are parties to this Convention) require an Apostille on documents which qualify as norwegian public documents.

Any official Government document with an original signature and seal on it can be authenticated by Notaries Public. Business documents must be certified by the relevant chamber of commerce.

In Norway documents are validated with an Apostille stamp by the competent norwegian authorities or the Prefecture (Lokalet Fylkesmannen kontoret).
