A contract of guarantee is one of the most important concepts under the Indian Contract Act, 1872, especially for banking, commercial transactions, and competitive examinations. In a contract of guarantee, a surety undertakes to discharge the liability of the principal debtor if the debtor defaults. However, the liability of a surety is not absolute or perpetual.

The Discharge of Surety is governed by Sections 130 to 141 of the Indian Contract Act, 1872, which specify the situations where a guarantor is legally released from liability. Questions from these provisions are frequently asked in the Civil Judge Exam, PCS J Exam, and other judiciary examinations because they test conceptual clarity and application-based reasoning.

In this article, we will discuss every important ground for discharge of a surety, relevant judicial precedents, practical illustrations, and exam-oriented tips.

What Is Discharge of a Surety?

A surety is discharged when their legal obligation under the contract of guarantee comes to an end. Once discharged, the surety is no longer liable to pay the creditor for the obligations covered by the guarantee, either wholly or partially, depending upon the circumstances provided under the Act.

Governing Provisions

1. Discharge by Revocation of Continuing Guarantee (Section 130)

A continuing guarantee extends to a series of future transactions rather than a single transaction.

Under Section 130, the surety may revoke such guarantee at any time by giving notice to the creditor.

Important Points

• Revocation affects only future transactions.
• Liability already incurred remains unaffected.
• Notice to the creditor is mandatory.

Example

A guarantees payment of goods supplied to B up to ₹50,000.

Later, A sends notice revoking the guarantee.

• A remains liable for supplies already made.
• A is not liable for goods supplied after revocation.

Exam Tip

Remember:

Revocation = Future transactions only

2. Discharge by Death of Surety (Section 131)

Section 131 provides that the death of the surety operates as a revocation of a continuing guarantee unless the contract provides otherwise.

Key Features

• Applies only to continuing guarantees.
• Future liability ends automatically.
• Estate of the deceased may remain liable for previous transactions.

Illustration

If a bank loan guarantee covered future advances and the guarantor dies, the guarantee generally ceases for advances made after death unless the agreement expressly states otherwise.

3. Discharge by Variance in Contract (Section 133)

Section 133 protects the surety against unauthorized changes in the contract between the creditor and the principal debtor.

If the creditor and debtor alter the original contract without the surety's consent, the surety stands discharged.

Why?

The surety agreed to guarantee a particular contract—not a modified one.

Example

A guarantees repayment of a loan payable in 12 monthly installments.

Without informing A, the creditor changes the repayment schedule to quarterly installments.

Since the contract has materially changed, A may be discharged.

Important Note

Every alteration does not discharge the surety.

Only material and prejudicial changes generally attract Section 133.

4. Discharge by Release of Principal Debtor (Section 134)

Section 134 states that if the creditor releases the principal debtor from liability, the surety is also discharged.

This includes:

• Express release
• Legal discharge
• Conduct having the effect of releasing the debtor

Example

A bank signs an agreement permanently waiving B's outstanding loan.

The guarantor cannot subsequently be made liable for the same debt.

5. Discharge by Composition, Giving Time or Promise Not to Sue (Section 135)

Section 135 protects the surety when the creditor changes the repayment arrangement without obtaining the surety's consent.

The surety is discharged if the creditor:

• Enters into a composition with the debtor
• Gives additional time for repayment
• Promises not to sue the debtor

Illustration

A bank grants the borrower an additional three years to repay the loan without informing the guarantor.

The guarantor may be discharged because the repayment terms were altered without consent.

Judiciary Exam Pointer

Do not confuse:

• Section 133 – Change in contract terms.
• Section 135 – Composition, extension of time, or promise not to sue.

This distinction is frequently tested in PYQs.

6. Discharge When Creditor Impairs Surety's Remedy (Section 139)

A surety has the right to recover money from the principal debtor after paying the creditor.

If the creditor does something—or fails to do something—that harms this right, the surety is discharged.

Example

If valuable security held by the creditor is negligently destroyed, the surety's recovery rights are affected.

Therefore, the surety may be discharged.

7. Discharge by Loss of Security (Section 141)

Section 141 provides another important safeguard.

If the creditor:

• loses,
• releases, or
• voluntarily parts with

security given by the principal debtor without the surety's consent, the surety is discharged to the extent of the value of that security.

Illustration

Suppose:

• Loan = ₹10 lakh
• Collateral worth ₹2 lakh is lost due to the creditor's negligence.

The surety's liability reduces by ₹2 lakh.

Why This Rule Exists

A surety should not suffer because the creditor failed to preserve valuable security.

Important Judicial Decisions

1. Sita Ram Gupta v. Punjab National Bank

The Court held that the surety could not revoke the guarantee because he had expressly agreed that the guarantee would remain continuing and irrevocable.

Principle

The statutory right under Section 130 may be restricted by the terms of the contract if the surety has knowingly accepted such conditions.

2. Anirudhan v. Thomco's Bank Ltd.

The Court held that every variation does not discharge the surety.

If the variation is beneficial to the surety and causes no prejudice, Section 133 does not apply.

Principle

Only material and prejudicial changes result in discharge.

3. Chekkara Ponnamma v. A.S. Thammayya

The surety failed to prove the amount recovered from the sale of the debtor's assets after death.

Consequently, the Court refused to grant recovery.

Principle

The burden of proof lies upon the surety seeking discharge or reimbursement.

Difference Between Sections 133 and 135

This comparison is highly important for Civil Judge Exam prelims.

Previous Year Question Trend (PYQ)

Questions generally focus on:

• Grounds of discharge
• Difference between Sections 133 and 135
• Continuing guarantee
• Effect of death of surety
• Loss of security
• Case law-based problem questions

Most prelims questions are objective, while mains examinations expect application of statutory provisions with supporting judgments.

Preparation Strategy for Judiciary Aspirants

For Prelims

• Memorize Sections 130–141.
• Revise illustrations.
• Solve PYQs and topic-wise Mock Test questions.
• Prepare one-line distinctions between important sections.

For Mains

Frame answers in the following order:

1. Definition
2. Relevant section
3. Statutory rule
4. Illustration
5. Case law
6. Conclusion

This structure helps secure better marks.

For Interview

Interview panels often ask practical questions like:

"If a bank extends the repayment period without informing the guarantor, what happens?"

Answer by directly referring to Section 135 and explaining that the surety is discharged because the creditor altered the repayment arrangement without consent.
