Once the bank has received the necessary information and funds, it will issue the cashier's check. The bank then deducts the amount of the check from the individual's account and places the funds in its own account as a guarantee of payment. The check is then signed by a bank official and stamped with the bank's seal.
The act of signing the check is considered an endorsement, which serves as proof of the payer's intent to transfer funds to the payee. In a financial transaction where one party pays with a check, the person receiving the funds must endorse the check with a signature.
