I was living with a man that I have asked to leave immediately. He does not pay rent, will buy a few groceries once in a while, buys gas when he wants to go to his hometown. His name is not in the rental picture as I am renting from a family member. He says I cannot force him out. I told him I would bring the sheriff if he did not go peacefully. He did leave but I am not sure if he can do anything about me asking him to leave. Need advise...
