If you suspect that your sister is abusing your mother, the first action you should take would be to contact your local Adult Protective Services agency. They can advise and assist you on dealing with this situation in a way that facilitates protection of your mother's best interest. As a live-in caregiver, your sister can technically be "fired" by you, the guardian, and instructed to leave. If she refuses to leave, then she is trespassing on your mother's property, and you can call the police to remove her. If all these options fail, then you should get in touch with an eviction attorney to file an unlawful detainer lawsuit. Remember that you as guardian have the authority and obligation to act in your mother's best interest. If you were in your mother's shoes, you would likely consider all of these options to get an unwanted, neglectful caregiver out of your house.
