Guardianship And Conservatorship Process

My grandmother has dementia and is no longer able to safely manage her medical care, living arrangements, or finances. She does not have a valid power of attorney or advance directive, and she is no longer capable of signing one. I have been preparing a petition for guardianship and conservatorship. There are two co-petitioners. I am the only person available and willing to serve. The second co-petitioner is my grandmother’s great-granddaughter by marriage, but she cannot serve due to other obligations. My father, who is the Ward’s son, initially believed he could care for her and serve as guardian. However, his treating neurologist has now provided a written letter stating that he is medically unable to care for my grandmother or serve as her legal guardian. He remains in denial about his limitations. Most of my evidence is from a few months ago and the petition has been signed since October *. I plan to file an emergency petition. Is this the best route?

yes
