I don't know how the eviction laws vary state to state. But I would start with small claims court if you want to do it without an attorney.. . You prove you own the house or whatever. Then you state your case and that's it. The people have to get out and you can ask for the money owed too. Here in MI it costs $45.00 to file.. . Go to your local courthouse and they will point you in the right direction. Good Luck!
