My youngest sister has guardianship over father with vascular dementia. He wants to fire her. Can he change attorneys on his own to do that? The guardianship started when his wife of 38+ yrs filed for divorce. (Our stepmother). She tricked him into signing over the house and everything to her. Had him convinced that all he needed was his truck and a $20,000. Plus a Fema trailer to live in. We got involved and sister was granted temporary guardianship. 2 days later our stepmother changed her mind about divorce. They are still living together after 1 1/2 yrs. My father wants to fire my sister and get his wife as guardianship. She doesn't take care of him and we all know that she is doing it to keep everything. Father is much older than she is. Sister has financial and medical guardianship over him. Can he get his own attorney? Or does he have to go to court to get that done?
