Pierce Butler, United States v. Butterworth-Judson Corporation…
“ But a bank having notice that a deposit is held by one for the use of or as security for another has only such right of set-off as is not inconsistent with the rights of the latter. Here, the banks had knowledge of the agreements, under which these balances constituted security for the advance made by the United States. By acceptance of the moneys furnished in accordance with the agreement, their right of set-off was made subject to the rights of the United States and the obligations of the contractor. ”
