Rights and Duties of a Banker (JAIIB PPB 2026): Lien, Set-Off & Secrecy

What can a bank legally do when a customer owes money on a loan or overdraft? And what does the bank owe the customer in return? The rights and duties of a banker answer exactly that. And they form one of the most heavily tested areas of the JAIIB syllabus.

This 2026 guide breaks the topic down completely. You will learn every right a banker can exercise. Every duty a banker must honour.

And how courts and recovery laws apply each one. It is written for JAIIB PPB 2026 aspirants. But it is equally useful for working bankers.

Anyone curious about Indian banking law.

Why the Rights and Duties of a Banker Matter

When you open an account. The bank does not merely hold your cash like a locker. In law. Your deposit becomes the bank's money, and the bank becomes your debtor. When you borrow, the roles flip and you become the debtor.

This banker-customer relationship is the foundation for everything that follows. Because money changes ownership. The bank earns certain enforceable rights to protect itself. And accepts certain duties to protect you. Understanding this balance is the heart of JAIIB Chapter 18.

The Rights of a Banker (When a Customer Owes Money)

A banker has four classic rights you must know cold for the exam. Each one is a separate tool for recovering or securing dues. Let us take them one by one.

1. Right of General Lien

A lien is the right to retain a customer's goods or securities until a debt is paid. A banker enjoys a general lien. Which is wider than an ordinary lien: it covers all dues. Not just those linked to a specific item.

Key points to remember:

• It applies to securities. Goods that come into the bank's possession in the ordinary course of business.
• A general lien usually gives the right to retain. Not automatically to sell. Sale typically needs an explicit agreement or a pledge.
• It does not apply to items left for safe custody or to a specific purpose (for example. Securities deposited for a particular loan).

Example: A customer pledges shares with the bank. Later defaults on an unrelated overdraft. Under a general lien. The bank may retain those shares against the outstanding dues.

2. Right of Set-Off

The right of set-off lets a bank combine two accounts of the same customer. Adjust a credit balance against a debit balance. If your loan is overdue but your savings account holds a balance. The bank can use one to clear the other.

Conditions a banker must satisfy before exercising set-off:

1. The accounts must be in the same name and same capacity.
2. The debt must be certain and due (not merely contingent or future).
3. Reasonable notice should generally be given to the customer.
4. There must be no agreement to the contrary preventing set-off.

Example: A customer's personal loan EMI is overdue. The same customer holds a savings balance at the same bank. In the same individual capacity. After notice. The bank applies set-off and adjusts the overdue amount from savings.

3. Right of Appropriation

When a customer owes money on more than one account. Pays without saying which debt to clear. Who decides?

First, the customer may direct how the payment is applied. If the customer is silent. The bank may appropriate the payment to any debt it chooses.

For a running account such as an overdraft. The famous Clayton's Rule applies: the first item on the debit side is discharged by the first item on the credit side. In short. The earliest debt is paid off first by the earliest credit.

4. Right to Charge Interest, Commission and Incidental Charges

A banker is entitled to be paid for lending money. Providing services. This right covers:

• Interest on loans, overdrafts and advances, as per the agreed rate.
• Commission and service charges for drafts, remittances, cheque collection and similar services.
• Penal charges when a customer owes money beyond the due date. Subject to RBI's prevailing rules on penal charges.

For exact ceilings. Fair-practice norms and the current treatment of penal charges versus penal interest. Confirm on the latest official IIBF notification and RBI circulars.

Banker Rights Compared: Lien vs Set-Off vs Appropriation

Students lose easy marks by confusing these three rights. This comparison table makes the differences obvious.

The Duties of a Banker

Rights come with responsibilities. The two duties examiners love most are the duty to honour cheques. The duty of secrecy.

Duty to Honour Cheques

A banker must honour a customer's cheque when the account holds sufficient. Properly applicable funds and the cheque is in order. Wrongful dishonour can damage the customer's reputation. Expose the bank to a claim for damages.

Duty of Secrecy (Confidentiality of Accounts)

A banker must keep the customer's account details confidential. This duty continues even after the account is closed. But it is not absolute — the law recognises clear exceptions. Which we cover next.

Duty of Secrecy: When Disclosure Is Allowed

The duty of secrecy bends in four well-known situations. A handy memory hook is RIGHT: Required by law. Interest of the bank, General public interest, and consenT of the customer.

• Under compulsion of law: court summons, income-tax authorities, or investigation into fraud.
• In the bank's own interest: for example. When a customer owes money and the bank must take recovery action.
• In the public interest: suspected money laundering or terrorist financing.
• With the customer's express consent: sharing details with an authorised third party.

Laws That Compel Disclosure

Several statutes can override secrecy. The most exam-relevant include:

• Bankers' Books Evidence Act — certified bank records can be produced as evidence.
• Income Tax Act — authorities can require account information.
• SARFAESI Act and RBI guidelines. Support disclosures for loan recovery. Credit reporting when a customer owes money.
• Credit information sharing. Defaults are reported to credit bureaus to protect the wider system.

Garnishee Order vs Attachment Order

Both orders stop a bank from paying out a customer's funds. But they come from different authorities. Confusing the two is a classic exam trap.

A Garnishee Order is issued by a court at the request of a judgment creditor. The bank becomes the "garnishee". Must freeze the debtor's balance to the extent ordered. It is usually issued in two stages: an order nisi (freeze. Show cause) followed by an order absolute (pay the creditor).

An Attachment Order is generally issued by a tax or government authority (such as the Income Tax Department) to recover dues owed to the government. In both cases. The bank must not honour the customer's cheques to the extent of the attached amount.

How to Study This Topic for JAIIB PPB 2026

This chapter is high-yield. Low-effort if you study it the right way. Use this simple plan:

1. Build the skeleton first. List the four rights and the core duties on a single page. Memorise the headings before the detail.
2. Learn the conditions, not just the names. Examiners test the conditions for set-off. The limits of lien far more than definitions.
3. Master the contrasts. Lien vs set-off, garnishee vs attachment, customer vs banker appropriation. The comparison tables above are your revision sheet.
4. Practise application questions. Turn each example into a question and solve it. Then attempt full-length mock tests to lock in speed.
5. Revise with our free guides in the final week and re-read the official syllabus once.

Common Mistakes to Avoid

• Assuming a general lien always allows sale. It allows the bank to retain. Sale generally needs a pledge or specific agreement.
• Ignoring "same capacity" in set-off. A personal account. A partnership account are not in the same capacity. So set-off usually fails.
• Treating the duty of secrecy as absolute. Remember the four exceptions (RIGHT) — disclosure can be lawful.
• Mixing up garnishee and attachment. Court versus tax/government authority is the deciding line.
• Forgetting who appropriates first. The customer's direction comes before the bank's choice.

Frequently Asked Questions

What is the difference between right of lien and right of set-off?

A lien is the right to retain goods or securities until dues are paid. Set-off is the right to adjust a credit balance against a debit balance across the same customer's accounts. Lien acts on assets; set-off acts on account balances.

Can a bank exercise set-off without informing the customer?

As a fair practice. The bank should give reasonable notice before applying set-off. The debt must be certain. Due, and held in the same name and capacity. Always check current RBI fair-practice guidance and the latest official IIBF notification.

Is the banker's duty of secrecy absolute?

No. Secrecy yields to four exceptions: disclosure required by law. In the bank's interest. In the public interest, and with the customer's consent. The duty otherwise continues even after the account closes.

Who issues a garnishee order and who issues an attachment order?

A garnishee order is issued by a court for a judgment creditor. An attachment order is usually issued by a tax or government authority to recover its dues. Both freeze the customer's funds to the stated extent.

What is Clayton's Rule in appropriation?

Clayton's Rule applies to running accounts like overdrafts. It states that the first amount credited goes to clear the first amount debited. In effect, the earliest debt is discharged first by the earliest credit.

Final Word: Turn This Chapter Into Easy Marks

The rights. Duties of a banker reward students who understand the logic. Not just the labels.

Hold the debtor-creditor idea in your head. Learn the conditions behind each right. And keep the comparison tables close during revision.

Do that. And the lien-versus-set-off questions. The secrecy exceptions. And the garnishee-versus-attachment traps become guaranteed marks in JAIIB PPB 2026. Study smart, revise often, and walk into the exam with confidence.
