There is always the possibility that if you made a bank deposit for a friend and the money deposit resulted from an improper receipt by your business associate, you could be charged with money laundering.If you just deposited the money in a bank account for your business associate without knowing that the money was received as a result of an ill gotten purpose does not suggest that you had an improper intent from a criminal standpoint to assist in a money laundering operation.To be on the safe side, you might consider consulting with a criminal defense attorney about the situation you are writing about further.
