My question involves a roommate in the State of: Oregon

She is still technically on the lease here, she has not given any written notice, to us or the property mgmnt company. She is dodging my calls, I had to quietly slip her a note at her job, because I knew she couldnt refuse it with out creating a scene, I said nothing, the envelope only had her name on it. (but I fear I may hav eoverstepped some legal thing there,, I was desperate). So her name is on lease.. no notice. and now is stating that she will use her boyfriend (the reason she has moved, we will not let him live here,, he is a registered sex offender, didnt tell us.. I had to reasearch is through country court) to move her belongings out of house. As long as it was storage unit I had not issue, but I have repeatidly told her he is to not set foot on the property, told him too (and heis one large scarey guy) but she says the house property mgmnt company says she can because her name is still ont he lease.. blahh blahh blahh.. and fi I call the police we will see what happens. The property ownr told us before this new nonsence, that if this sex offender stepped on property to call him...
what do I do... I want her out... I am going to sue her in small claims she is into me for soooomuch money I am not adding it up, because I may need an ambulance when I do. (she spent my entire settlement I got from a case).
Summary - Garage gone.. her stuff here now.. she is on lease here, but has not given any notice.. new month.. no word, no email. no call... we do not know if she will pay rent and we do not want her to.. we want her out.. and Property managemtn company hates roommate issues.. andare waiting for her to sign some form.
How do I get her out!
