Depending on how long she lived with you, you will probably have to file an unlawful detainer (eviction) action against her and then get a writ of possession to have her removed from the house. I suggest that you contact an experienced landlord/tenant or real estate attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. He/she would then be in a better position to analyze your case and advise you of your options.
