What do you do when your parent makes a decision and siblings blame it on you?

Without knowing what the issue is, how many siblings, and what you mean by a 'smear campaign' - talking amongst themselves behind your back? or something that could matter, such as reporting you to APS? - it is hard to know what to suggest.

You say your parents are afraid of your siblings' temper. Are you, too? Are you on speaking terms with them still, or not really?

1RareFind is quite correct; there is nothing sinister in itself about your siblings' wanting reassurance that their parents' finances are in order. Getting everything down on paper in clear summary form *for your parents' use* would be a sensible thing to do anyway. And then if they wish to share that information with their children they are free to do so. Do you think that might make them back off a bit?

Livingsouth, get used to it. Caegiving is not for the faint of heart, you need a very thick skin. I cared for mom for four years and the onslaughts continued the entire time from my twisted sisters. One advantage of your situation is that you have the POA, I did not, so made everything very difficult. Good luck.

Is a family meeting, with all parties including your parents, a possibility?

With elder financial abuse being so common, it's very easy to be suspicious. What I would do is just speak to your parents and encourage them to speak for themselves to the people who are ganging up on you

Oh my! I have POA because I was tired of being bullied. Been living with mom for 5+ years and caring for her more intently last 2-3 years. No one calls or visits. Or it is the obligatory hour. I have been diapering her for months and now I am learning using a feeding tube. Sisters are furious I have POA! Are you kidding me?! I got POA because otherwise mom would be in a home & I would be her only visitor. I also got POA to protect myself from their bullying. I am actually afraid of them at times!
