I have what probably is a dumb question, but here goes: I understand the thrust of the work done here is toward understanding how to withstand scrutiny from the IRS and the courts. Proper record forming is essential. However, what problems might arise if someone makes a deposit with a bank, then simply writes a check for, "Pay to the order of lawful money 12 USC 411 in the amount of ____"?

Seems to me the bank would have no difficulty understanding this, and would still have the benefit of using the funds on deposit. As long as other checks are never drawn against the account, wouldn't this prove the trust account never paid out anything but lawful money?
