Hi there. José M. spanish atorney
If she has her name at the propiety register you could do nothing to avoid her to live there.
She has no chance to take out you name of the propiety register
In order to get legal security you have two ways to manage with her. To get an agrement to sell one part to each other or to go to court to sell the propiety at court and get some cash and forget her
The second way is slow and expensive at court
I am on line if you need more help
