Rights & Discharge of the Surety — Contract II (Special Contracts) Notes

Rights of Surety

A surety who pays up is not a volunteer throwing money away. The law arms him with a full set of rights — against the debtor he backed, against the creditor he paid, and against anyone who stood surety alongside him. The trick is to group these rights by whom they run against.

What rights does a surety have?

When a surety pays the creditor, he should not be worse off than the creditor was. So the Act gives him rights in three directions. Keep the grouping — it is the answer’s skeleton.

A. Rights against the principal debtor.

Right of subrogation (s.140). On paying the debt, the surety steps into the creditor’s shoes: he acquires all the rights the creditor had against the principal debtor, including any securities. (Subrogation = substitution into another’s legal position.)
Right of indemnity (s.145). In every contract of guarantee there is an implied promise by the principal debtor to indemnify the surety; so the surety can recover from the principal debtor whatever he rightfully paid under the guarantee (but not sums paid wrongfully).

B. Rights against the creditor.

Right to securities (s.141). The surety is entitled to the benefit of every security the creditor holds against the principal debtor at the time the guarantee is given, whether or not the surety knew of it. If the creditor loses or parts with such a security without the surety’s consent, the surety is discharged to that extent.
Right of set-off. When sued by the creditor, the surety can use any set-off or counter-claim the principal debtor would have had against the creditor.

C. Rights against co-sureties.

Right of contribution (ss.146–147). Where several sureties guarantee the same debt, they share the burden. Absent agreement, they contribute equally (s.146); where they have guaranteed different sums, they contribute rateably up to their respective limits (s.147). (Treated fully in Topic 8.)

The favourite problem — guarantee of a minor’s debt. A minor’s agreement is void ab initio (from the start), so there is no valid principal debt to fall back on. What then of the surety? The dominant view (following Kashiba v. Shripat and the reasoning in later cases) is that the surety is liable as a principal debtor, not merely as a secondary party — because there is no enforceable principal obligation for his liability to be collateral to. So the creditor can proceed directly against the surety. (There is a contrary line — cf. the English Coutts & Co. v. Browne-Lecky (1947) — that a void principal debt leaves nothing to guarantee; the Indian position turns on the surety having knowingly contracted to stand behind an incapable debtor, which is what makes him liable as a principal debtor.)

🧩 WORKED EXAMPLE — guarantee for a minor’s loan

Facts. A bank lends to M, a minor, on S’s guarantee. M defaults. S argues: “A minor’s contract is void, so there is no principal debt, so I owe nothing.”

Rule. A surety’s liability is normally co-extensive with the principal debtor’s (s.128); but where the principal debtor is a minor (no valid debt), the surety is treated as a principal debtor and is directly liable.

Apply. There is no enforceable debt against M, but S undertook the risk knowing the position; S cannot hide behind the minor’s incapacity.

Conclusion. S is liable to the bank as a principal debtor.

Section 140, Indian Contract Act 1872: “Where a guaranteed debt has become due, or default of the principal debtor to perform a guaranteed duty has taken place, the surety, upon payment or performance of all that he is liable for, is invested with all the rights which the creditor had against the principal debtor.”

In Simple Terms: Pay the debt, and you inherit the creditor’s rights against the debtor (s.140), you can claim reimbursement from the debtor (s.145), you get the benefit of the creditor’s securities (s.141), and you share the load with co-sureties (ss.146–147).

Case Laws

[C-2] Bank of Bihar v. Damodar Prasad (1969) — the creditor may proceed against the surety without first exhausting his remedies against the principal debtor; the surety’s liability is immediate on default.
State Bank of India v. Indexport Registered (1992) — a decree can be executed against the surety even before proceeding against the principal debtor.
Amrit Lal Goverdhan Lalan v. State Bank of Travancore (1968) — loss of a security by the creditor discharges the surety pro tanto (to that extent) under s.141.

Discharge of Surety

A surety agrees to a particular bargain on particular terms. Change the bargain behind his back, let go a security he was counting on, or release the debtor, and the deal he signed up for no longer exists. The law’s discharge rules are really one idea: the surety is entitled to have the contract kept as it was.

How is a surety discharged?

Group the grounds into two families — discharge by the act of the parties and by operation of law — and remember the near-misses that do not discharge, because that is what the problems test.

A. By revocation.

Revocation of a continuing guarantee (s.130) — the surety may revoke as to future transactions by notice to the creditor.
Death of the surety (s.131) — automatically revokes a continuing guarantee for future transactions, in the absence of a contrary contract.

B. By the creditor’s conduct.

Variance in terms (s.133). Any variation in the terms of the contract between the creditor and the principal debtor, made without the surety’s consent, discharges the surety as to transactions after the variance.
Release or discharge of the principal debtor (s.134). If the creditor makes a contract that releases the principal debtor, or does any act or omission whose legal consequence is the debtor’s discharge, the surety is discharged.
Composition, extension of time, or promise not to sue (s.135). If the creditor, without the surety’s consent, compounds with, gives more time to, or promises not to sue the principal debtor, the surety is discharged.
- Exception (s.136): mere forbearance — where the creditor makes an agreement with a third person (not the debtor) to give time — does not discharge the surety.
- Exception (s.137): mere forbearance to sue the principal debtor, or to enforce any other remedy, does not discharge the surety (unless the contract says so). This is a classic trap.
Impairing the surety’s remedy (s.139). If the creditor does any act inconsistent with the surety’s rights, or omits to do an act his duty to the surety requires, and the surety’s eventual remedy against the principal debtor is thereby impaired, the surety is discharged.
Loss of security (s.141). If the creditor loses or parts with a security without the surety’s consent, the surety is discharged to the extent of the value of that security.

C. What does NOT discharge the surety — the exam’s favourite decoys:

Mere forbearance to sue the principal debtor (s.137).
A change in the personal relationship between the parties (e.g. a divorce, a fresh partnership) that does not alter the terms of the guaranteed contract.
Non-disclosure that is not material, or the principal debtor’s own misconduct not caused by the creditor.

🧩 WORKED EXAMPLE — extension of time vs mere forbearance

Facts. S guarantees D’s loan to a bank. (i) The bank, without asking S, formally agrees with D to extend the due date by six months. (ii) In a different case, the bank simply does not sue D for a year but makes no agreement.

Rule. A binding agreement to give time discharges the surety (s.135); mere forbearance to sue does not (s.137).

Apply. In (i) there is a fresh agreement varying the debtor’s obligation without S’s consent — s.135 applies. In (ii) the bank only delayed; there is no agreement — s.137 applies.

Conclusion. In (i) S is discharged; in (ii) S is not discharged.

Section 133, Indian Contract Act 1872: “Any variance, made without the surety’s consent, in the terms of the contract between the principal debtor and the creditor, discharges the surety as to transactions subsequent to the variance.”

In Simple Terms: Change the deal, release the debtor, give him a fresh extension, or throw away a security — all without the surety’s consent — and the surety walks free (wholly or to that extent). But simply going slow on suing the debtor does not let the surety off.

Case Laws

M.S. Anirudhan v. Thomco’s Bank (1963) — an alteration beneficial to the surety, or one he consented to, does not discharge him.
Amrit Lal Goverdhan Lalan v. State Bank of Travancore (1968) — creditor’s loss of security discharges the surety to that extent (s.141).
State of M.P. v. Kaluram (1967) — where the creditor’s own act loses a security, the surety is discharged pro tanto.

Continuing Guarantee

A guarantee for a single sack of flour ends when that sack is paid for. But a guarantee for “all the flour you supply my shop this year” keeps standing behind sale after sale. Telling those two apart — one transaction versus a series — decides how far the surety’s liability runs and how he can escape it.

What is a continuing guarantee?

Some guarantees cover just one deal; others cover an ongoing course of dealing. The Act separates them because they end in different ways.

Section 129 defines it: a continuing guarantee is a guarantee which extends to a series of transactions. A specific (or simple) guarantee, by contrast, covers a single transaction and is exhausted once that transaction is complete.

How do you tell which is which? Read the words and the intention. “I guarantee the price of the 10 bags you deliver today” is specific — one transaction. “I guarantee payment for goods you supply from time to time up to ₹5,000” is continuing — the ₹5,000 is a ceiling on liability at any one time, not a cap on the total number of dealings; fresh supplies are covered as old ones are paid off.

How a continuing guarantee is revoked or terminated — the examinable half:

By notice of revocation (s.130). The surety may, at any time, revoke a continuing guarantee as to future transactions by giving notice to the creditor. He remains liable for transactions already entered into before the notice.
By the surety’s death (s.131). The death of the surety operates, in the absence of a contract to the contrary, as a revocation of a continuing guarantee for future transactions. Liability for past transactions survives against his estate.
By the ordinary discharge grounds. Variance (s.133), release of the principal debtor (s.134), or novation (s.62) also bring a continuing guarantee to an end, exactly as for any guarantee.

🧩 WORKED EXAMPLE — specific or continuing?

Facts. S writes to a supplier: “In consideration of your supplying goods to D from time to time, I guarantee payment up to ₹5,000.” D buys and pays for goods worth ₹5,000, then buys another ₹5,000 worth and defaults.

Rule. A guarantee for a series of transactions is continuing (s.129); a stated sum is usually the ceiling of liability at any moment, not a limit on total dealings.

Apply. The words “from time to time” show a series; the ₹5,000 caps S’s exposure at any point, not the number of supplies. The first ₹5,000 was paid; the second ₹5,000 default is covered up to the ceiling.

Conclusion. It is a continuing guarantee; S is liable for the ₹5,000 default.

Section 129, Indian Contract Act 1872: “A guarantee which extends to a series of transactions is called a ‘continuing guarantee’.”

In Simple Terms: A continuing guarantee stands behind many transactions, not just one. The surety can stop it for the future by giving notice (s.130), and it also ends on his death (s.131) — but he stays liable for whatever was already done.

Case Laws

Offord v. Davies (1862) — a continuing guarantee can be revoked as to future transactions before they are acted on.
Hargopal v. People’s Bank of Northern India (1935) — the scope (specific vs continuing) turns on the words and the intention of the parties.

Nature and Extent of Surety’s Liability

How much does a surety owe? Exactly what the principal debtor owes — no more, unless he has agreed to less. That one word, co-extensive, in section 128, is the whole topic; and because the law leans in the surety’s favour, he is called a “favoured debtor”.

What is the extent of the surety’s liability?

The starting rule is one of measurement: the surety’s liability tracks the debtor’s.

Section 128 states it: the liability of the surety is co-extensive with that of the principal debtor, unless it is otherwise provided by the contract. Co-extensive means equal in amount and extent — whatever the principal debtor is liable to pay, the surety is liable to pay, including interest and costs, but no more (unless he expressly limited it, which he may do).

Two consequences:

The surety cannot be made to pay more than the principal debtor owes.
The surety can limit his liability by the terms of his contract (e.g. “up to ₹50,000 only”).
The creditor need not first sue the principal debtor or exhaust securities; on default, the surety is immediately liable (Bank of Bihar v. Damodar Prasad).

“Surety is a favoured debtor.” Because he backs another’s debt without benefit to himself, the law construes his contract strictly in his favour (the principle of strictissimi juris — of the strictest right/interpretation). Any material change made without his consent (ss.133–139) tends to release him, and doubts in the guarantee document are resolved in his favour. That protective stance is why he is called a favoured debtor.

🧩 WORKED EXAMPLE — co-extensive liability

Facts. D owes a bank ₹1,00,000 plus ₹10,000 interest. S guaranteed the loan without any limiting words. D defaults.

Rule. Under s.128 the surety’s liability is co-extensive with the debtor’s, unless the contract limits it.

Apply. S guaranteed without limitation, so his liability equals D’s — principal plus interest and costs.

Conclusion. S is liable for ₹1,10,000 (plus recoverable costs), the same as D.

Section 128, Indian Contract Act 1872: “The liability of the surety is co-extensive with that of the principal debtor, unless it is otherwise provided by the contract.”

In Simple Terms: The surety owes exactly what the debtor owes — no more, unless he capped it. But the law reads his promise strictly in his favour, so he is a “favoured debtor”.

Case Laws

[C-2] Bank of Bihar v. Damodar Prasad (1969) — surety’s liability is immediate and co-extensive; creditor need not first proceed against the principal debtor.
Maharashtra State Electricity Board v. Official Liquidator (1982) — the surety’s liability stands even where the principal debtor is wound up, unless the guarantee provides otherwise.

Co-surety and Contribution

Three friends jointly guarantee one loan. The debtor defaults, and the creditor recovers the whole amount from just one of them. Is that unlucky surety left to bear it alone? No — the law makes the others share, even though they never agreed among themselves to do so.

What is contribution between co-sureties?

When two or more people stand surety for the same debt, they are co-sureties. Fairness says the burden should be shared, and the Act imposes sharing even without any agreement between them.

Equal contribution (s.146). Co-sureties who are liable to pay an equal amount are bound, as between themselves, to contribute equally to the whole debt (or to the part left unpaid by the principal debtor).
Contribution where sums are unequal (s.147). Where co-sureties have guaranteed different sums, they contribute rateably (proportionately) up to their respective limits, again as between themselves.
Effect of release (s.138). Release by the creditor of one co-surety does not discharge the others; nor does it free the released co-surety from his responsibility to the other co-sureties for contribution.

The right of contribution is independent of any contract between the co-sureties; it arises from the equity of equal treatment (Deering v. Earl of Winchelsea).

🧩 WORKED EXAMPLE — sharing the loss

Facts. P, Q and R jointly guarantee a ₹90,000 debt, each without a stated limit. D defaults entirely, and the creditor recovers the full ₹90,000 from P alone.

Rule. Co-sureties liable equally must contribute equally (s.146); one who pays more than his share can recover the excess from the others.

Apply. Each of the three should bear ₹30,000. P paid ₹90,000, so he may recover ₹30,000 each from Q and R.

Conclusion. P recovers ₹60,000 in contribution, leaving each co-surety bearing ₹30,000.

Section 146, Indian Contract Act 1872: “Where two or more persons are co-sureties for the same debt or duty … in the absence of any contract to the contrary, [they] are liable, as between themselves, to pay each an equal share of the whole debt, or of that part of it which remains unpaid by the principal debtor.”

In Simple Terms: Co-sureties share the load. Equal guarantees mean equal shares (s.146); different amounts mean proportionate shares up to each limit (s.147); and releasing one does not free the rest (s.138).
