The term 'customer' of a bank is not defined by law. Ordinarily, a person who has an account in a bank is considered its customer. Banking experts and the legal judgements in the past, however, used to qualify this statement by laying emphasis on the period for which such account had actually been maintained with the bank. In Sir John Paget's view "to constitute a customer there must be some recognisable course or habit of dealing in the nature of regular banking business." This definition of a customer of a bank lays emphasis on the duration of the dealings between the banker and the customer and is, therefore, called the 'duration theory'. Accord- ing to this viewpoint a person does not become a customer of the banker on the opening of an account, he must have been accustomed to deal with the banker before he is designated as a customer.
DEFINITION OF A CUSTOMER IN THE COMMERCIAL BANK
The above-mentioned emphasis on the duration of the bank account is now discarded. According to Dr. Hart, "a customer is one who has an account with a banker or for whom a banker habitually undertakes to act as such."
"Broadly speaking, a customer is a person who has the habit of resorting to the same place or person to do business. So far as banking transactions are concerned he is a person whose money has been accepted on the footing that the banker will honour up to the amount standing to his credit, irrespective of his connection being of short or long standing."
