Evicting a family member in IL?
I have a quick question. Unfortunately my younger sister is a drug addict. My mother put her through rehab 3 times already and again she is back on drugs. Today my mother had enough and wanted her out of the house. She called the police to have her removed. When the police came they said that this was her legal residence and that if she wanted her removed she would have to get a eviction paper from the court. They said they don't have any cause to remove or arrest her because she didn't break the law. (basically she was harassing my mother verbally for hours trying to get money from her).
My mother didn't argue with the police about it, but is this true? My sister has never paid a day of rent in her life. Heck she doesn't even work. I've been trying to research this on my own and the only thing I can find according to the law is eviction laws about people paying rent or have a written lease. So I guess my question is can't my mother just kick her out? Any advice on what my mother can say to the police to set them straight? Or are the police right in this case?
