My friend's stepson is in his late 20s. He is out of work & has moved his obnoxious out-of-work girlfriend in with him. My friend was the one to invite her to stay with them for a short period. Unfortunately, there was no contract saying when she'd be expected to leave. Does the girlfriend now have any sort of 'Squatter's Rights' that will make it hard for my friend to get her out of the home? I'm not sure how long she has had this girl in her home.
