Thanks for your email.
You would need to discuss these issues with a Spanish lawyer, particularly the issues with the property, as Spanish Law applies.
I do know of a firm in London who has a dual qualified lawyer that would be able to assist with this issue. Please let me know if you want contact details.
I will opt out to open the question up again. Do message me direct if you want the contact details. Good luck.
Would you still like assistance with this?
