A pass book is a record of a customer's bank account that is maintained by the bank. It displays deposits credited to the account on the right side and debits for payments from the account on the left side. According to case law, the pass book constitutes the official record of transactions between the bank and customer if it is examined regularly by the customer. A wrong entry favorable to the customer only constitutes a settled account if the customer believes it is true and acts on it in good faith, such as by writing checks based on the incorrect higher balance. However, a customer cannot rely on entries made by a bank employee that are fictional.
