Hi Desi, yes I e-mailed them today and found this out also...When my husband applied for his Schengen, they only required a marriage certificate (stamped by the Tunisian Ministry of Interiors or by The Tunisian Embassy in London), his and my passport and the application form. These are the requirements if the applicant is a spouse of UK/EU National, no bookings or any other proofs (bank statements, etc.). He applied through The French, but as they all are using the same application form it could well be the case with the Spanish, worth checking as it saved a lot of paperwork.
And I am pretty sure this "right to free movement" would apply all over so I'll have a look into it...
Here's their reply...
The visa type / purpose of travel you require is Spouse of an EU Citizen. (Schengen visa application form)
You will only need to provide his passport, your passport and marriage certificate.
So I have checked the Schengen Application form and it does state "Spouses of EU Citizens do not have to fill in certain sections of this application form marked with an * while exercising their freedom of movement"
So I looked and all the boxes marked with an * are the proof of travel, bookings details, proof of funds for the trips etc etc so they DONT have to fill these in. You only have to fill in your name address / his name etc and provide your passport and marriage certificate.
Lots of hassle saved then
