My question involves landlord-tenant law in the State of: WI. Two months ago my roommate's mother was kicked out of her boyfriends house. We agreed to take her in temporarily while she tries to find a place and help us make rent. We cleared her staying for a short while with the landlord but she's not actually on the lease and he doesn't know she's helping pay the rent. Currently, we can handle the cost ourselves, but she believe she's going to stay longer now. We no longer want her here because she's become trouble, making us feel uncomfortable, unsafe, and unwelcome in our own apartment.
I guess I have several questions:
- Do we need to give her any advanced warning if push comes to shove and she flat-out refuses to leave?
- Can we deny her the right to have "guests" over?
- Could our landlord kick us out if she's staying longer than she originally claimed?
Thank you for any advice.
