Usufructs are useless. I can't count how many farang I know that had one. But we're forced out of their house by the wife's/girlfriends family. They make living their unbearable. One example her 2 son's move in after the house was just built. They both had jobs until the house was completed. Than like magic they both got fired and moved in. Causing all sorts of problems. Always needing money for food,phone and partying at the house with their friends. It got so bad my friend moved back to his home land and just left everything.
Second real story. I guy I know built a new home with his girlfriend on her land. Had all the paper work to protect him. Guaranteeing he had use for 30 years. But when his girlfriend brings her new German boyfriend home he is forced out. Got the police involved and everything. They said she owns the land. She can have anyone she wants to live there. Up to him if he wants to stay. He left after 2 months completing the construction.
