Consumer Fraud confused23

I deposits money in my account he sends me back the deposit slip and the money I gave him am I n trouble if I keep it

Why would anyone who deposits money in his or her account be in trouble?

No way you could be in trouble, if things are as you claim, unless the money is stolen loot!!!!
Chances are the bank will discover the error and deduct the money from your account since it was inadvertently returned to you and not actually put in your account.
