My so called friend moved in with his girlfriend. I offered him a free place to stay for 2 months to get on his feet. He insisted he would rather pay and be able to stay. We verbally agreed to 700 a month for everything( a steal in NJ) He has paid 400 but is 1000 behind. Since I offered him a free place and he chose to pay I'm having principal issues with these late or non payments. At this point I don't want to him here cause he's not doing what he said he would. Hes been here 5 weeks. I never gave him a key cause he never paid in full. I can get him to sign something promising to move out in 30 days will this help or do anything? To make matter worse I may think he's doing cocaine or maybe something else too. He barely leaves the house like a true squatter. I realize this is the worst friend I probably have. What to do? Does he have any right to stay here? Are there squatters rights in nj? How can I get him out with out violence or fighting or force ? Could a judge order him to sign a lease or get out?
