Step-mother trying to evict me ?


So I moved in with my dad and his wife about 10months ago . She’s never liked me and last night she told my dad she was going to evict me , and even go the legal way with it . My dad and her are both on the lease , I am not I just live here as my father is letting me . My dad told her she can’t evict me , he won’t let her . But can she actually evict me ?
