I let a man and his children move into a room in the house I am renting. I have verbal permission from my landlord that I can sub-let a room to help me cover the rent. The man has paid me one time and it is now time for he and his family to move out but he refuses to leave. We cannot continue living like this. I have nothing written between the two of us. He also has his travel trailer parked in my drive way. I was told that because he has been here for longer than 30 days, he has established residency and the only way to get him out is through formal eviction. What are the specific steps I need to do and in what order to process this and how long will it take?
