Unless your mother also has a conservator, then she would appear to retain the right to evict you. There does not need to be a "good" reason for the eviction. She owns the property and she can do with it whatever she wishes. You may have some counter-claims, if you have renovated or improved the premises, but it would appear you are going to need to find a new place to live. You can appeal to your mother's guardian, or to her conservator, if there is one. Otherwise, I do not think you have a legal right to stay.
