I have the same dilemma here in the UK, my son came to stay for 2 days over a year ago but refused to leave to go back to his apartment which he eventually lost. He will not pay any rent, steals from me and my husband, does not pay anything towards utility bills and constantly leaves the TV on in my living room (which he sleeps in and me and my husband cannot use anymore). He makes a mess everywhere my living room looks like a homeless persons squat. I have called Police when he has assaulted me I once had a concussion from him pushing me over in my kitchen and I hit my head on the counter top. Police do not want to get involved. Only way I can get him out is going to cost a lot of money, or get some guys to rough him up, neither option is possible? Help?
