I have a one-yr lease on an apartment. I rented out a room to my current rommmate. I have a written month-to-month agreement with him. I was out for a month and in my absense he moved his girlfriend into the apartment because "she had problems with her roommate and had no place to go".
I had a chat with my roommate and told him that I had very rented out the apartment to only one person and there is no room for a third person. His girlfriend moved out in a few days but continued to store her belongings in the apartment (some in common areas). Now she is back.
I intend to give my roommate a 30 day notice to quit. However I do not want his girlfriend to continue living here either in the 30 day period.
My specific question is can I prevent the girlfriend from entering the apartment.? She is not on his lease - is she trespassing?
