text: It depends. Some banks, instead of sending back your checks with every statement, send only copies of the checks, and this may include all checks deposited to the account.  If you go online and look at the statement, you can click on any line item on the statement and it will bring up an image of that item, front and back.  If Chase does that then yes, by going into the online statement and clicking on any item she will be able to see an image of that item.\n\nIf the deposit item in question is a check drawn on a local bank, you may be able to go to that bank and cash it, then take the cash and make a cash deposit into your joint checking account.  This way all your mom can see is a cash deposit.  if you don't even want her to see the cash, and need to pay some bills, take the cash and go to the post office and buy money orders for the amounts of the bills you need to pay, and send the money orders as payments.  This way, your mom will not see any deposit at all, or at most a very much reduced one.\n\nI used to do all this to keep it looking like I had no income and no deposits to my checking account.  Once I went to the post office and bought a total of $5,000 in a whole bunch of money orders, and only $300 or so actually made it as cash into my checking account.  For all intents and purposes if you looked at my checking account it looked like I was dead broke and in abject poverty.
