A relative has left their car in my garage for the last 10 years. I want to sell my house and they won't move it. They could move it to their own property but don't want to. It was always meant to be temporary. I have brought it up several times over the years and they just brush me off with excuses every time. I have ran out of patience. What legal route do I need to take. I don't want to dispose of or sell the car I just want to get it towed to their driveway, but Google seems to suggest I could be prosecuted for criminal damage if I do
