Legalisation of documents

All the official documents issued by a UK authority must be legalised in order to take effect in San Marino. The documents must have an Apostille stamp, which can be obtained by: 

Legalization Office – Foreign And Commonwealth Office 
P.O.Box 6255 – Milton Keynes MK10 1XX – 
Tel.: 03700 00 22 44 
Web address: www.gov.uk/get-document-legalised 
email: legalisationEnquiries@fco.gov.uk

After legalising the documents they need to be translated in Italian. A list of certified translators you may find here.

Citizens need to mail the original documents (after having them legalised & translated in Italian) to the postal address of the Honorary Consulate of San Marino in London for further processing:
