(With Recent Judgments & Case Law Analysis – Indian Law Perspective)
Since 30,000 words cannot be delivered in one single message, I will provide it in structured parts (like a dissertation). This is Part I.
PART I
INTRODUCTION, MEANING, NATURE AND LEGAL FOUNDATION
1️⃣ INTRODUCTION
The relationship between banker and customer is one of the most important topics in Banking Law and is frequently asked in LLB examinations, judiciary exams, and even UGC NET law papers.
Banking is the backbone of modern commercial society. Every individual, business, or government institution depends on banks for financial transactions. Therefore, understanding the legal nature of this relationship is essential.
This relationship is not simple. It may take different legal forms such as:
- Debtor and creditor
- Principal and agent
- Bailor and bailee
- Trustee and beneficiary
- Pledgor and pledgee
- Lessor and lessee
The nature depends on the type of transaction between banker and customer.
2️⃣ WHO IS A BANKER?
Under the , Section 5(b):
“Banking means accepting for the purpose of lending or investment of deposits of money from the public, repayable on demand or otherwise, and withdrawable by cheque, draft, order or otherwise.”
Thus, a banker is a person or company which:
- Accepts deposits
- Repays on demand
- Allows withdrawal through cheque/draft
- Uses deposits for lending/investment
3️⃣ WHO IS A CUSTOMER?
The term “customer” is not defined in the Banking Regulation Act.
Classical Definition:
In the famous English case:
🔹
The Court held:
A customer is one who has an account with a bank.
However, Indian courts have interpreted it more broadly.
A person becomes a customer when:
- The bank opens an account
- There is intention of regular dealing
- Even a single transaction may be sufficient (modern view)
4️⃣ ESSENTIAL ELEMENTS OF BANKER–CUSTOMER RELATIONSHIP
- Account must be opened
- Deposits must be accepted
- Banker must agree to honour cheques
- Relationship must be lawful
5️⃣ PRIMARY NATURE: DEBTOR–CREDITOR RELATIONSHIP
This is the most important and frequently asked question in exams.
🔹 Landmark Case:
The House of Lords held:
When money is deposited in a bank:
- It becomes the money of the banker.
- The banker becomes debtor.
- The customer becomes creditor.
The bank is not trustee of deposited money.
Important Principle:
The banker can use deposited money for business. The only obligation is to repay when demanded.
Indian Position
Indian courts follow the same principle.
In modern Indian decisions, High Courts have reiterated that:
- Deposits create a debt
- Bank is not trustee (unless special circumstances)
- Customer cannot claim specific currency notes
6️⃣ RECENT SUPREME COURT JUDGMENT (2025)
🔹
Facts:
- A branch postmaster misappropriated deposit money.
- Entries were made in passbook but not in official records.
- Later money was returned.
Issue:
Whether repayment removes misconduct?
Supreme Court Held:
- Banker–customer relationship is based on mutual trust.
- Misappropriation is serious misconduct.
- Mere repayment does not erase breach of trust.
- Courts should not interfere in departmental findings.
Importance for LLB Exam:
This case clarifies:
- Even though relationship is debtor–creditor,
- Trust and integrity are fundamental.
Exam Tip:
If question asks:
“Discuss whether banker is trustee of customer’s money.”
You must mention:
- Classical rule (Foley v. Hill)
- Then discuss Indraj case to show modern trust element.
7️⃣ DIFFERENT TYPES OF RELATIONSHIPS
The relationship changes depending on transaction.
(A) Debtor and Creditor
When:

When:

(C) Principal and Agent
When:

But may arise when:
