Two years ago my mother, while in sound health and mind, made me, her son, power of attorney. At this time, her relationship with my sister was strained and since my sister is an RN, she was made my mother's MPOA. Though I am my mother's POA, I live about 900 miles away. When these documents were initiated, we were the same distance apart. My mom's health and awareness are now failing and my sister is her primary caregiver. My mom stayed with my sister previously when she was in good health and it was a disaster. My mom had to move to independent living. Now my sister is providing excellent care for my mom, but she is trying to take control of her finances, as well. She is going out of her way to prevent me from fulfilling my duties as mom's POA and attempting to set up other accounts by dragging my mom to different banks and establishing new accounts and transferring funds from where I have established POA. Now she has taken my mother to her attorney to revoke my POA and establish a POA under the pretense of needing her POA closer to mom. The attorney won't allow her to revoke my POA, but suggested that a trust be established with a neutral party as trustee. Her attorney suggested a bank as trustee, but there are fees involved and when my mom was in good health and before making me her POA, she wanted no part of a trust. I feel that my mom is being manipulated and there is no need for any changes. What do I need to do to best provide my mom her wishes?
