My sister is the live in caregiver for my 85-year-old mom and refuses to communicate with me. Can my sister keep me from my mom?

Is it possible your sister resents the fact that she's the one taking care of your mom and not you? Could that be the reason she appears to be retaliating against you by not allowing you to see her?

No she can't. If needed, talk to a lawyer. Or have a welfare check done on your mother to see what is really going on. Or both, talk to a lawyer and have the check done. Our local senior center has a free lawyer come in once a month to give individual advice. Maybe you could do that if $ is a problem. But no she can't stop you from seeing her.

No she can't. Your a grown up, not a kid that "isn't allowed to". Of course you can see your own Mom. How can she possibly be stopping you. Just go &see her. If you have to go as far as to take a police escort to her home, or where ever she is. I'd be damned if I would let ANYONE tell me I couldn't see my own mother. GOOD LUCK!!!!

Well what's her big problem? Is this an on going thing between the two of you? Can you bring in a family friend or someone that your sister WILL let in, to mediate?
