Cashier’s Check Definition

A cashier’s check is a type of check issued and guaranteed by a bank. Prior to issuing the check, the bank impounds the full check amount in a special fund used only to guarantee payment of issued cashier’s checks. Thus, a cashier’s check will never bounce and is considered a type of certified or guaranteed payment. Cashier’s checks may alternately be called a bank check, an official check, a teller’s check, a treasurer’s check, or a bank draft.
