I want to do this without increasing my financial risk. My father recently suffered a health problem that resulted in some severe mental health problems. He is the only person with access to his small savings and checking account. During the worst part of his illness, he believed he was rich and nearly drained his bank account. He is getting better but this incident also revealed he likely has some underlying mild dementia. Do we need to pursue guardianship or is there an alternate approach we can take to manage his finances and prevent him from completely depleting his funds if he suffers another episode?
