What about banking arrangements and bill payments?
You should open a special bank account for the dependent adult. All payments should be directed to that account and all bills paid out of it. It is extremely important that the money belonging to the dependent adult and the money belonging to the trustee be kept separate at all times! Keep all bank records, statements, receipts and canceled cheques. You may hire someone to help you with bookkeeping and accounting tasks and the payment may be made out of the dependent adult's estate.
