My question involves an EVICTION of a roommate in the State of: Washington
-she is not on the lease (renting the 2nd room of the apt I am renting)
-she has been behind up to 2 months at a time in rent and has never paid some utilities
-trashing her part of the apartment and common areas
-I caught her doing cocaine and told her she had to be out
-verbal notice given and written notice given 2/08
-she has told me that she cannot be out till March (likely the end) and I know if I give her that long she will continue to drag her feet
-what steps do I have to take to physically remove everything she has there and change the locks on her?
