Adult daughter refuses to move out
Daughter nearly 29 moved in to attend school, and I was willing to pay her tuition and allow her room and board if she would help with utilities, complete school and follow reasonable house rules. She was laid off from her p/t job, neglected school for several weeks, and has been partying in my basement at all hours, despite my actually interrupting the socializing, and chasing people out of my house. One man (one of these unwelcome "guests" has yelled at me twice ("What's your problem, Lady?"), and it has taken repeated requests to get him to leave. Each time I tell him not to return. Daughter continues to let him, and other friends in and screams at me when I attempt to throw them out. 2 days ago I notified that rude man that if I find him on my property again, the police will be called.
Last month, I handed her a written eviction notice, effective on or before the last day of December. She tells me alternately: "You'll be sorry when you never see me again!" and "I'd like to see you try to make me leave!"
Ugly as this already is, I'm sure it is likely to heat up even more.
Does anyone have suggestions for this type of situation in WA State if my daughter does not leave by the end of Dec? I will change the locks in early January, will continue to keep throwing out unwelcome guests, and won't hesitate to make good my promise to call the police if that one person returns.
