My distant sister whom has only recently showed up when my father was moved into a nursing home along with my mother. Both have dementia mom worse than my dad. My sister recently came into the picture since she blocked my phone so I was unable to contact her to let her know of my fathers fall and hospitalization and move to nursing home. I could not tell her of existing will yet she was aware of my POA. Now she wanted POA to be able to talk to drs which I was totally fine with yet I find out 3 months later she had gotten a lawyer for my father (whom already had one - a close family friend) coerced my father into signing ANOTHER WILL and making her POA also yet she only wanted to be able to speak to drs which I could have made happen if she would have bit her pride and asked me. so now I'm trying to make changes back to original will (she has added her son etc to the will which is not what my father wanted) I made changes but now I'm fighting with her lawyer she hired. Do I have ANY RECOURSE since she went behind my back and I didn't find out any changes nor I would have never gotten a new POA if I had not have run into her at the house. Please I need help I am run down and overwhelmed I've been taking care of my parents ALL by myself all these years and now I she walks in and created so much stress for me I haven't had a vacation in 4 years while she has wandered the country with her rich boyfriend only stopping through to see parents on her way to Hawaii or other places I'm soo done shes no longer a sister to me but I need advice. Can I have any recourse of what she did?? I still have control of guardianship of my mother I guess shes to lazy to stay long enough to go to court..... to fight that. Please help I'm at my wits end and cant live my own life (work home and my large involvement with animal rescue) without stress.
