A certified check is an item which the bank has guaranteed to pay by virtue of deducting, at the time of presentation of the check for certification, the amount of the check from the depositor's account and setting it up in a special account called "certified checks outstanding." A certified check is very distinctly the liability of the bank. The entries made at the time of certification are as follows:

Debit: Due to Depositors (37)........

$2,000

Credit: Certified Checks Outstanding (36) ...........................

$2,000

An adequate record must be kept of the checks certified, and this is usually maintained by the paying teller in the form of a pad showing the numbers and the amounts of the checks certified, and of the accounts for whom the certifications are made. From this record the deposit ledger bookkeepers make the entries in the customers' accounts after having marked the deposit at the time of certification so that no withdrawal can be made of the funds to be withheld. When the checks finally come in for payment by the bank they are checked off from the certified record and thus "killed." Open items on the certified record must always prove with the general ledger account.
