What is the difference between Apostille Legalisation and Embassy Legalisation?
The “Apostille” is needed whenever you intend to use documents from any country outside of Spain within Spain. This is because Spain is a member of the Hague Convention, which establishes a new, standardised form of Legalisation. On October 5, 1961 several nations joined to create this simplified method of legalising documents through the Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents. More information about the Apostille can be found at wikipedia.
