Key Takeaways (Read This First)
- The banker's right of set-off lets a bank combine a customer's accounts. Adjust a credit balance against a debit balance.
- It works because the banker-customer relationship is a mutual debtor-creditor relationship.
- Five conditions must be met: same customer. Same capacity, debt due and payable, no restrictive agreement, and (usually) notice.
- Set-off adjusts account balances; a lien retains goods or securities. Do not mix them up.
- Trust accounts and capacity mismatches are the most common exam traps.
What Is the Banker's Right of Set-Off?
The banker's right of set-off is the legal right of a bank to combine two or more accounts of the same customer. Adjust the balances against each other. In simple words. The bank can use the money lying in one account to clear what the customer owes in another account.
Imagine a customer has a credit balance in a savings account. An overdue loan in another. The bank can apply the savings balance to settle the loan dues. Provided certain legal conditions are satisfied. This protects the bank's money and reduces credit risk.
Because it sits at the heart of the banker-customer relationship, this topic appears in legal-aspects and principles-of-banking papers across JAIIB, CAIIB and CCP. Pair this read with our free mock tests to test recall immediately.
Why the Right of Set-Off Matters in Banking
Set-off is not just an exam topic. It is a daily tool in real banking operations. Here is why it matters.
- Faster recovery: Banks recover dues quickly without going to court.
- Lower credit risk: Idle credit balances offset risky debit balances.
- NPA control: Adjusting accounts helps keep loans from slipping into non-performing status.
- Customer discipline: Borrowers know surplus funds can be applied to dues.
For a promotion candidate. Understanding the why makes the conditions far easier to remember in the exam hall.
Legal Nature and Foundation of the Right
The right of set-off is not granted by a single statute. It flows from common law principles. Judicial decisions, and the implied contract between banker and customer. The foundation is the mutual debtor-creditor relationship.
- When a customer deposits money. The bank becomes the debtor and the customer the creditor.
- When a customer borrows money. The customer becomes the debtor and the bank the creditor.
Since both parties owe each other in the same overall relationship. The law allows the bank to net these mutual debts. That mutuality is the legal heartbeat of set-off.
Types of Set-Off in Banking
Examiners frequently ask you to identify the type of set-off. Learn these three clearly.
1. Legal Set-Off
This is the most common and most exam-relevant type. It arises automatically once all legal conditions are fulfilled. No special agreement is needed.
2. Equitable Set-Off
Courts allow this on grounds of fairness. Even when strict legal requirements are not fully met. A court may permit adjustment if the transactions are closely connected.
3. Contractual Set-Off
This arises from a specific agreement between the bank and the customer. Most modern loan documents include a clause that expressly permits the bank to set off balances.
Essential Conditions for the Banker's Right of Set-Off
This is the single most tested section. Memorise all five conditions. If even one fails, the bank cannot exercise the right.
Condition 1: Same Customer (Mutuality of Accounts)
The accounts must belong to the same person. A bank cannot adjust accounts that belong to different individuals.
Condition 2: Same Capacity (The Most Important Concept)
The accounts must be held in the same legal capacity. This is where most candidates lose marks. Even if the name is identical, a difference in capacity blocks set-off.
- Individual account vs individual account → Allowed
- Individual account vs trust account → Not allowed
- Individual account vs partnership account → Not allowed
Condition 3: Debt Must Be Due and Payable
The liability must be existing, certain and due. A future or contingent liability cannot be adjusted. If the loan instalment is not yet due. Set-off does not apply to it.
Condition 4: No Restrictive Agreement
If an agreement restricts or excludes set-off. The bank cannot exercise the right. The contract overrides the default position.
Condition 5: Notice to the Customer
Banks generally give prior notice before exercising set-off. As a matter of good practice. In urgent situations, immediate action may be taken. For the exact procedural stand. Confirm on the latest official IIBF notification and your bank's internal policy.

Practical Banking Applications
Examiners love application-based questions. Work through these real-world scenarios.
Savings Account and Loan Adjustment
If a customer has a sufficient credit balance in a savings account. An outstanding loan that is due. The bank can recover the loan amount by adjusting the savings balance.
Fixed Deposit Adjustment
If a fixed deposit is marked under lien against a loan. The bank can adjust it against the loan dues when they fall due.
Joint Account Case
Set-off is not allowed when a joint account is used to recover an individual liability. The capacities differ, so mutuality fails.
Trust Account Case
Funds held in a trust account cannot be used to recover a personal loan. The money does not beneficially belong to the borrower.
When the Banker Cannot Exercise the Right of Set-Off
Reverse-direction questions are common. Keep this no-go list ready.
- Accounts held in different capacities

| Subject matter | Money in accounts | Goods, securities, instruments | A specific payment received |
Important Case Laws You Must Quote
Naming the right case law instantly boosts your answer in descriptive papers.
Devaynes vs Noble (Clayton's Rule)
Introduced the first-in-first-out principle for appropriation in a running current account.
National Westminster Bank Case
Confirmed the bank's right to combine accounts of the same customer.
Halesowen Presswork Case
Clarified that set-off can be exercised only when the conditions are satisfied. And an agreement can suspend the right.
Advanced Concept: Right of Combination of Accounts
Before applying set-off. The bank combines a customer's multiple accounts. Treats them as one unit for recovery. Combination is the preparatory step; set-off is the actual adjustment. Many MCQs hinge on this fine distinction.
Role in Loan Recovery and NPA Management
Set-off is widely used in loan recovery, NPA management and credit monitoring. By offsetting idle credit balances against overdue accounts. Banks cut credit risk and lift recovery efficiency. This links neatly with topics like NBFC lending. Credit appraisal in your syllabus.
