Mari,

Why can't your friend can still control her own finances?
I thought that she was moving just because she can't drive.
Is that something her brother(s) are insisting upon?

I can understand your concerns about her moving away. You will be unable to see her, and you won't be able to check up on her welfare. I'm so sorry (((HUGS)))

I hope that everything works out, and these brothers of hers end up being better men than they appear/seem to be, and she gets good care without getting preyed upon.
