What is Deposit Slip?

Legal Definition
A deposit slip is a form supplied by a bank for a depositor to fill out, designed to document in categories the items included in the deposit transaction. The categories include type of item, and if it is a cheque, where it is from such as a local bank or a state if the bank is not local. The teller keeps the deposit slip along with the deposit (cash and checks), and provides the depositor with a receipt. They are filled in a store and not a Bank, so it is very convenient in paying. They also are a means of transport of money. Pay-in slips encourage the sorting of cash and coins, are filled in and signed by the person who deposited the money, and some tear off from a record that is also filled in by the depositor. Deposit slips are also called deposit tickets and come in a variety of designs. They are signed by the depositor if the depositor is cashing some of the accompanying check and depositing the rest.
