My sister and her husband are deadbeats. Before my father died 4 years ago, my sister instituted a credit card scheme where she had about 20 credit cards she maxed out and then went crying to my father that she needed him to pay them. She would bring him the bottom half of the credit card bills, so there was no detail. My father had no idea what she was doing with the credit cards, but like a blind sheep, he paid them all....to the tune of $625,000. Now she is milking my mother. She comes up every couple of months to visit her (she livest 45 minutes away) and has my mother write her checks for "investment". Neither she nor he husband work. This is elder abuse. My mother doesn't know any better. She does have an attorney who is POA, and an accountant who is financial POA. They both know what has gone on, and is going on. I don't think they are being vigilant enough. What can I do? And who can I contact. I told her accountant that all checkbooks must be removed from her apartment and he must be the only one to write checks from now on. My father left my mother a big estate, and my sister knows that. There will be none left at the rate things are going. Plus, I am the one who is being penalized financially! Any ideas how to stop my sister in her tracks, but good?
