My Mom had total knee replacement surgery in feb 2012, my sister talked Mom into putting her on Mom's bank account with ATM card while she recovered so she could pay the bills well she did a lot more than that. My brother who had cerebral palsy was on hospice at the time and two younger sister also special needs live in Mom's home so do I. I was very busy taking care of all of them but was noticing that my sister had plenty of money to spend, her not having a job I looked into it come to find out she had been doing online transfers of my brother & sisters social security money into Mom's account and using her ATM card to withdraw it my Mom is payee not my sister . As my brother got sicker I stayed by his side 24/7, 4 months later he passed away. Last month Mom had my sister taken off bank account after finding out what she had been doing , now my sister keeps calling Adult Protective Services making false reports on me to get me out of the way, then she plans on having Mom claimed incompetent and be her payee & my 2 sisters. My Mom and I haven't even had a chance to deal with my little brothers death and now this. HELP!
Probably wouldn't hurt to contact a lawyer experienced in elder care, so you can further protect your family from the sister. A good talk with someone at the bank would be in order as well. You just have to cover all your basis. A good paper trail and let as many people as necessary know what has happened.
Good luck and God bless!
