Also, each state has it's own rules about what can and can't be paid. I would be concerned that the agency was just depositing money into her account.
I would second this. I worked with a "flat fee" agency, so I did not pay expenses directly, but when I finalized in my state I had to give an accounting of how much I paid in eparent expenses and what that money went for. My finalization could have been denied if I had paid money that was not legal in my state (or couldn't prove what it was paid for), so I would be careful with that aspect as well.
