I live in a trailer park with my friend Justin whom owns the trailor. He pays the park 500 a month to leave it on the lot. About 2 years ago I lived here with a boyfriend and he called the police on me one day for being there, it got dropped in court because he didn't show up and knows I wasn't trespassing. Now living here with Justin (for about 3 months) they say I'm not allowed. I never signed anything nor was there any legal documentations by the police filled out. Are they allowed to kick me out?
