Please speak with a lawyer in your community who has experience with landlord tenant cases. The attorney should be able to give you advice and be your advocate in Court. Since I do not know what state you are in and Landlord Tenant law is different in each state , I can not give you any further guidance. The situation has gone beyond asking nicely for rent you are not being paid. Be sure you ask the lawyer about fees and costs and if you can recover them from your tenant. You may want to speak with a Legal Aid or Legal Services attorney to see if you qualify for low or no cost legal help.
