The two words get used interchangeably in business conversation, and in law they are different animals with different parties and different liability. Confuse them in a contract and you can owe far more than you intended, or find the protection you thought you had does not exist.
An indemnity under Section 124 is a two-party promise to cover another's loss, with primary liability; a guarantee under Section 126 is a three-party arrangement in which a surety backs a principal debtor's obligation to a creditor, with liability that is secondary but co-extensive.
The bottom line
Indemnity: two parties. "I will cover your loss." Liability is primary and arises when the loss happens.
Guarantee: three parties. "If they do not pay, I will." Liability is secondary, arising on the debtor's default, but co-extensive with the debtor's under Section 128.
Where it bites: a surety who pays can recover from the principal debtor. An indemnifier has no such recourse — the promise was their own.
A contract of indemnity
Under Section 124 of the Indian Contract Act, a party — the indemnifier — promises to save the other, the indemnified or indemnity-holder, from loss caused either by the indemnifier's own conduct or by a third party.
It is a two-party arrangement, and the obligation triggers when the specified loss actually occurs.
Indemnity clauses are everywhere in commercial contracts. A vendor indemnifying a client against third-party IP infringement claims arising from the vendor's product is the standard example, and the one most service agreements contain.
A contract of guarantee
Under Section 126, a guarantee is a promise to perform the obligation, or discharge the liability, of a third person in case of their default. It always involves three parties:
- the principal debtor, who owes the obligation;
- the creditor, to whom it is owed; and
- the surety, who guarantees it.
The classic case: a bank lends to a company, the principal debtor, only because a director, the surety, guarantees repayment to the bank, the creditor. If the company defaults, the bank recovers from the director.
The differences that matter
| Feature | Indemnity (S.124) | Guarantee (S.126) |
|---|---|---|
| Number of parties | Two | Three |
| Nature of liability | Primary (the indemnifier's own) | Secondary (arises on debtor's default) |
| Number of contracts | One | Three (debtor-creditor, creditor-surety, debtor-surety) |
| When liability arises | When the loss occurs | When the principal debtor defaults |
| Purpose | To compensate for a loss | To assure performance/repayment |
| Surety's recourse | N/A | Surety can recover from the principal debtor |
How far the surety's liability goes
Section 128 makes the surety's liability co-extensive with that of the principal debtor. The surety is liable to the same extent as the debtor unless the contract says otherwise.
That word does more work than guarantors expect. It is secondary in the sense that it arises only on default, and once it arises it is not smaller than the debtor's. Directors signing personal guarantees routinely underestimate this.
By contrast an indemnifier's liability is primary. It is their own promise to cover a loss, not a backstop for someone else's failure.
Where a surety pays, they typically step into the creditor's shoes and can recover from the principal debtor. An indemnifier has nobody to turn to.
Which one you need
Use an indemnity where you want one party to absorb a specific risk or loss — IP claims, breaches, third-party damages. That is the standard tool in service and supply contracts.
Use a guarantee where you want a third party to stand behind someone's obligation — a parent company backing a subsidiary's contract, a director backing a loan, a personal guarantee on a lease.
They are often used together, and a lender will commonly take both.
A worked example
A startup takes a ₹50 lakh business loan. The bank requires two things.
The company indemnifies the bank against certain losses, which is a two-party promise. And the founder gives a personal guarantee, which is a three-party arrangement: founder as surety, bank as creditor, company as principal debtor.
If the company defaults, the bank can proceed against the founder under the guarantee, and the founder, having paid, can recover from the company.
The two instruments do different jobs. One covers defined losses; the other backstops the whole repayment.
Common mistakes
- Calling a guarantee an indemnity, or the reverse, which creates uncertainty about who is liable and when.
- Not capping indemnity liability, leaving it open-ended.
- Signing a guarantee without registering that liability is co-extensive with the debtor's.
- Forgetting the surety's right of recovery against the principal debtor.
- Loose drafting of the trigger, so nobody can say when the obligation actually arises.
A drafting checklist
- Decide whether you are covering a loss or backstopping a default.
- Name the parties correctly for the structure you chose.
- Define the trigger: loss occurring, or debtor default.
- Cap and scope indemnity liability wherever you can.
- For a guarantee, spell out the co-extensive liability and the right of recovery.
- Use distinct language for each. Do not blur the two in one clause.
Frequently asked questions
What is the difference between indemnity and guarantee? An indemnity is a two-party promise to cover another's loss. A guarantee is a three-party promise where a surety backs a principal debtor's obligation to a creditor.
Is a surety's liability primary or secondary? Secondary, arising only on the principal debtor's default — but co-extensive with the debtor's liability under Section 128.
Can a guarantor recover what they pay? Yes. A surety who pays generally steps into the creditor's position and can recover from the principal debtor.
Which is better for a lender? Often both: an indemnity for defined losses, and a guarantee to backstop repayment.
Can indemnity liability be unlimited? It can be, if you leave it undrafted, which is exactly why it should be capped and scoped.
I signed a personal guarantee. How exposed am I? To the same extent as the borrower, unless the guarantee limits it. That is what co-extensive means, and it is why the cap belongs in the document.
