My mother has dementia and I have a POA but I don't know how I go about taking control? She doesn't think she does anything wrong but will spend all of her money or find people to take people to her to the bank and then drains her account. Should I open a new account in my name? She will be getting disability payments soon but I worry she'll get a hold of it and spend it on frivolous things. How have others dealt with taking finances over when they don't think you need to?
