I have rented a house and signed a 18 month lease with my landlord. My roommate moved in as well but did not sign the lease. My roommate and I had a verbal agreement that he would be responsible for his half of bills. In the past two months my roommate has been verbally and physically abusive. Disrespectful and I have 3 small children in the home as well. What process do I need to take to get him out of my house.
