According to the spanish law he is the owner and if you ask her for money you will have to probe she owes that you claim for.
So, the chance to get some money back will depend on what you could probe
Yes, even you will have to pay you do not give her the money as a gift is she says so
Its hard to prove.
Of course. For the spanish law the propiety is not yours, is of both of you, you two have the same rights
If you want to ask her for money is another problem, but this propiety is of both of you
Please to rate positively the service
