Mom owes me $9000 and I can't stand it anymore?

I would sit her dawn & have a serious talk with her. I know it would be hard but I have heard about alot of people going through family courts to get the money back. You can explain that this has nothing to do with her but you need this money back. It may be hard to prove she used them so you may want to a way to make her sign off on something stating that she does in fact owe you the money.
