Elderly parent funding sibling's legal troubles and new business venture

[Anonymous]

They barely had a relationship years ago. Sister came back into picture before dad died. Suddenly super close to mom. Convinces mom not to get dementia evaluation. Next thing I know mom is making accusations against me and takes away financial POA-which is fine I never wanted it. She still takes care of her own finances so it's not like I was doing anything, but I know how much work it becomes. I back away. Mom tells me that I have been a bad daughter (we used to be close) and informs me she is now funding sister's legal troubles and her new business venture. Sister quits job and mom is then also funding private schools, housekeeping and expensive lifestyle until business venture takes off. Mom can afford this and still have money left for aging. If I do anything to try to "protect" her from financial abuse it will be turned on me. If she has dementia-it's early stage-still can seem pretty together. Mom was telling me this to punish me for not doing enough for her, not because she feels she is being taken advantaged of. I don't have the energy for this. Am I supposed to consult a lawyer? I have heard APS is pretty useless unless things are obvious. As long as my sister plans to take care of mom, I'd rather not get involved. I have posted before about other things related to aging parent. Brother passed away years ago and he was the only other person who knew my sister's dark side, but keep in mind mom is consenting.

Nope. You let them do what they are going to do. When/if your mom wastes all her money, you let her go to a nursing home.

OP you can't change this unfortunately. Save yourself.
