I have been sole caregiver for my 94 yr old mother for the past 10 yrs. Both my siblings were twice a year "visitors" even tho close geographically. Earlier this year, I was injured and had to be hospitalized. My sister had to take over caregiving. In the meantime, she had my mom change her will and, as POA, is capable of just about anything. She will not allow me to see my mom unsupervised. She, in my opinion, has used undue influence to convince my Mom that she now prefers to live with her. There are serious issues due to this, such as my having to leave my mom's residence and relocate. Difficult to do when I am still recovering from my injuries. My sister has her home up for sale due to self expressed financial concerns, ie she can not afford to keep up her payments on said home and has moved in with my mom. What recourse would you take?
This is looking like a war over Mom's assets of home and money--of who will live there and care for Mom.
I think that if you go to a lawyer there may be a State Appointed Guardian for your mother as an end result, in which case neither you nor your Mom will have control of home, money or where Mom is placed, which would likely be in a nursing home, with home sold to pay for her care. If you and your sister get into a fight over "control of Mom" and her assets in a court case for guardianship, that could be the end result.
I am guessing about all of that. It is sad that with your becoming ill and unable to care for your mother you have now no control over anything.
Certainly an hour of an attorney's time will let you know your options, your rights. So yes, I would suggest it.
