Furthermore, generally, the relationship of a bank customer and a banker is contractual. In other words, a customer to a bank in relation to the business of banking is any person having an account with a bank or for whom a bank has agreed to collect items and includes a bank carrying an account with another bank. – ARIWOOLA J.S.C. Union Bank v. Chimaeze (2014)
NATURE OF A BANK AND BANK’S CUSTOMER
per Lord Atkin in JOACHIMSON v. SWISS BANK CORPORATION (1921) 3 KB 110 COURT OF APPEAL where he held: “The bank undertakes to receive money and to collect bills for its customer’s account. The proceeds so received are not to be held in trust for the customer, but the bank borrows the proceeds and undertakes to repay them. The promise to repay is to repay at the branch of the bank where the account is kept, and during banking hours. It includes a promise to repay any part of the amount due against the written order of the customer addressed to the bank at the branch, and as such written orders may be outstanding in the ordinary course of business for two or three days, it is a term of the contract that the bank will not cease to do business with the customer except upon reasonable notice. The customer on his part undertakes to exercise reasonable care in executing his written orders so as not to mislead the bank or to facilitate forgery. I think it is necessarily a term of such contract that the bank is not liable to pay the customer the full amount of his balance until he demands payment from the bank at the branch at which the current account is kept.”
