I live in one state, and my sister lives in another. I live in the same state my mother has lived in for decades, and more than two years ago we had to move in with my mother because she couldn't live by herself any longer (dementia) and we couldn't afford any place else for her. I have complete power of attorney. However, a place has opened up that is (just barely) affordable in the state my sister lives in. Could we give my sister power of attorney in that state? It might be a bit more limited than mine, but it could make it so much easier for her to operate. However, I don't want MINE to be revoked because I handle most of her taxes, paperwork, etc. Is this possible? I have heard about there being joint Powers of Attorney (where they have to act in concert), but that is not what I'm talking about here. Does anybody know?
