Documents which are being presented for use in a country which is not party to the Hague Convention (relating to apostilles) will often request further legalisation and possibly embassy attestation. This usually involves having an apostille attached to the document and then carrying out further legalisation through the embassy of that country. This can add considerable complexity to the process as all embassies have different procedures and costs. It is also advisable to ask the person or authority that you intend to present the document to what their exact requirements are.
