My mother was diagnosed with Alzheimer's disease. She was living with me for three years but as the disease progressed I could no longer care for her. i have four other siblings but none of them would help me with mom and I was totally burnt out it and started affecting my health. I had to put my mother in the nursing home. We live in Jersey City. my Mom have very little money and is in the process of getting medicaid. I am her power of attorney but I know it is only good while she is alive. I am also on her bank accounts but how do I become the executor of her estate or have guardianship now to handle her business if she passes. What are the legal steps I need to take.
