Collateral (www.practicallaw.com/3-382-3343) consisting of cash, bank accounts, cash equivalents (www.practicallaw.com/6-382-3313) or the proceeds or rents derived from other collateral, held by the debtor in bankruptcy subject to creditors' liens (www.practicallaw.com/8-382-3581). Cash collateral can only be used by the debtor with the creditor's consent or if the court, after notice and a hearing, finds the creditor is adequately protected (www.practicallaw.com/8-382-3213) and authorizes such use. Until the debtor obtains consent from the creditor or court authorization to use, sell or lease cash collateral, the debtor must segregate it in a separate bank account and account for all such property in its possession and control.
