as far as i know, in spain you can have up to 10 000€ each each without giving any proof of where the money comes from,

10 000€ a year is not really a big amount for the,. just for you, and you can withdraw all your money in two years, in fact, 2 months if you do it 1 in december and 1 in january hehe,

any weay, better ask this to a lawer,
