So my uncle has power of attorney over my other uncle. And my mother and myself moved here from Oklahoma to California to move in with him and help take care of him. And since we have been here my uncle feels the need to put me out on the streets and that he doesn't want me to be here in his house at all. My uncle that's under the care wants my mom and myself to be here.
What happened that he doesn't want you around?
Dealing with that would be my 1st step.
If he lives in the same house and it is his property, yes he can have you evicted.
Have you and mom talked about what you would both do if he tries to evict you? I would have a plan in place.
