my mom is 80 and living with my brother and his wife. I and my 2 sisters help getting her to appts and such. we all live within a reasonable driving distance from each other. mom has become frail, has had a stroke (minor) and has chf. the problem: she has not updated her trust since her husband died 10 years ago, sold the house and has maybe 50 -75k left from it, overspends credit cards when she gets a chance - and will not sign a poa! I worry about the ramifications if she has another, more serious stroke with no poa in place. ideas? of course she's stubborn!
