Hi Vanessa

This is quite a complex matter as it involved 3 different jurisdictions (British, Norwegian and Spanish) and therefore you have to be in extreme careful as your ex-partner could sue you for child abduction if this is not properly, from a legal point of view, arranged.

I suggest that you hire a matrimonial law expert in Barcelona as it is a matter which requires you to have a closer relationship with your lawyer given the nature of the matter.

Regards
