As some of you may recall, sister is POA over Mom, her money, her health, and her life. Sister handles all of Mom's money. Should sister be giving me, the non-POA an accounting of the money. And how often, once a year, once a month? But as you also may recall POA is very stubborn and won't do it anyway.You would think she would want to give me an accounting to protect herself. Is it required that she do so?
