Relationship between the Banker and Customer


According to Section 3 of the Negotiable Instruments Act the term ‘banker’ includes any person acting as a banker. According to Halsbury’s Laws of England a banker as "an individual, partnership or corporation whose sole predominating business is banking, that is the receipt of money on current account or deposit account and the payment of cheques drawn by and the collection of cheques paid in by the customer."

A banker is one who in the ordinary course of his business, honors cheques drawn upon him by persons from and for whom he receives money on their account. No person or body corporate can be a banker who does not (1) take deposit accounts and current accounts, (2) issue and pay cheques and (3) collect cheques crossed and uncrossed for its customers. One claiming to be a banker must acknowledge himself to be one, and the public must accept him as such; his main business must be that of banking from which normally he should be able to earn his livelihood.


A customer is a person who has some kind of account, such as deposit or current with a bank and from this it follows that any person may become a customer by opening a deposit or current account or having some similar relation with a bank." To constitute a customer, there must be some identifiable course or habit of dealing in the nature of regular banking business. It is difficult to settle the idea of a single transaction with that of a customer. A customer is a person; he should have some kind of an account with the bank. The initial transaction in opening an account will not create the relation of a banker and customer. According to the ‘duration theory’ the relation of a banker and customer begins as soon as the first cheque is paid in and accepted for collection. In simple words a customer can be any person for whom the bank agrees to conduct an account.

Creditor and Debtor

When a bank grants loan and other credit facilities to the customer, the relationship between the banker and customer is reversed, that is Customer is Debtor and Banker is Creditor. In such cases banker doesn’t carry/ hold the money of the customer but it is the money of the bank in the hands of the customer. In all such cases when a customer’s account is over drawn, the customer does not cease to be a customer.
