Understanding When a Guarantee Ends
A guarantee is a serious commitment. When you sign as a guarantor for a loan, credit facility or commercial obligation, you become liable to pay if the principal debtor defaults. However, the law also protects guarantors in certain circumstances. Under the Contracts Act 1950, a guarantor may be discharged from liability if specific events occur—often without the guarantor even realising it.
This article explains the key situations where a guarantee can no longer be enforced against you, and what rights you have if you do end up paying on behalf of the debtor.
Variation of the Principal Contract Without Consent
One of the most important protections for guarantors is found in section 86 of the Contracts Act 1950. This provision states that 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 practical terms, this means:
- If the creditor and debtor agree to change the interest rate, repayment schedule, loan amount, or any other material term of the underlying contract, the guarantor is discharged unless they consented to that change.
- The variance does not need to be substantial or prejudicial to the guarantor. Even a minor change can trigger discharge.
- The guarantor remains liable for obligations that arose before the variance but is released from liability for anything that comes after.
This rule exists because a guarantor agrees to stand behind a specific arrangement. If that arrangement changes, the guarantor should have the opportunity to reassess the risk before remaining bound.
What Counts as a Variation?
Common examples include extending the loan tenure, increasing the credit limit, changing the nature of goods or services to be supplied, or altering payment terms. Even changes that might seem beneficial to the debtor—and indirectly to the guarantor—can still operate as a discharge if made without consent.
Release of the Principal Debtor
Section 87 of the Contracts Act 1950 provides that a surety is discharged by any contract between the creditor and the principal debtor by which the principal debtor is released, or by any act or omission of the creditor the legal consequence of which is the discharge of the principal debtor.
The logic is straightforward: if the creditor releases the debtor from the obligation, there is no longer any primary liability for the guarantor to guarantee. The guarantee is accessory to the principal debt. When the principal obligation ends, so does the guarantee.
This applies whether the release is express (a formal deed of release) or implied through the creditor's conduct. If the creditor does something that has the legal effect of discharging the debtor, the guarantor is similarly discharged.
Giving Time to the Principal Debtor
Section 88 of the Contracts Act 1950 addresses what happens when a creditor gives the principal debtor additional time to pay, compounds with the debtor, or promises not to sue the debtor.
The general rule is that such arrangements discharge the surety unless the surety assents to the arrangement.
Two related rules limit this protection. Under section 89, an agreement to give time that the creditor makes with a third person, rather than with the principal debtor, does not discharge the surety. Under section 90, mere forbearance by the creditor to sue the debtor or enforce any other remedy does not discharge the surety, unless the guarantee provides otherwise.
This protection exists because giving time to the debtor can prejudice the guarantor. The guarantor may have been willing and able to pay immediately and then recover from the debtor while the debtor still had assets. A delay could mean the debtor's financial position worsens, leaving the guarantor with no realistic prospect of recovery.
Guarantor Consent Clauses
Creditors who wish to give indulgences to debtors without losing their rights against guarantors must be careful to obtain the guarantor's assent. Many guarantee documents contain a clause by which the guarantor agrees in advance that the creditor may give time, vary terms or release security without discharging the guarantor. A well-drafted consent clause preserves the creditor's ability to pursue the guarantor even after giving extra time to the debtor.
Release of a Co-Guarantor
Section 91 of the Contracts Act 1950 states that where there are co-sureties, a release by the creditor of one of them does not discharge the others. Nor does the release free the released co-surety from their responsibility to the other sureties.
This means if you are one of three guarantors and the creditor releases one of your co-guarantors, you remain liable under your guarantee. The released co-guarantor, however, remains responsible to you and the other co-guarantors for their share if you end up paying.
The practical effect is that the release affects only the creditor's own claim against the released co-guarantor. It does not change the rights of contribution among the co-guarantors themselves.
Creditor's Acts Impairing the Guarantor's Remedy
Section 92 of the Contracts Act 1950 provides that if the creditor does any act which is inconsistent with the rights of the surety, or omits to do any act which their duty to the surety requires them to do, and the eventual remedy of the surety against the principal debtor is thereby impaired, the surety is discharged.
Examples might include:
- The creditor paying out funds to the debtor ahead of the agreed stages without the guarantor's knowledge
- The creditor failing to register a charge, resulting in loss of priority
- The creditor's negligent handling of collateral
Separately, section 94 gives the guarantor the benefit of every security the creditor held against the principal debtor when the guarantee was given. If the creditor loses that security, or parts with it without the guarantor's consent, the guarantor is discharged to the extent of the value of the security.
The key question is whether the creditor's act or omission has prejudiced the guarantor's ability to recover from the debtor after paying.
The Guarantor's Rights After Paying
If a guarantor does pay under the guarantee, the law provides important rights to help the guarantor recover what they have paid.
Right of Subrogation
Under section 93 of the Contracts Act 1950, a surety who has paid the guaranteed debt is invested with all the rights which the creditor had against the principal debtor. This is called subrogation.
The guarantor effectively steps into the shoes of the creditor. If the creditor held security, the guarantor can enforce that security. If the creditor had judgment against the debtor, the guarantor can execute on that judgment.
Right of Indemnity
Section 98 of the Contracts Act 1950 implies, in every contract of guarantee, a promise by the principal debtor to indemnify the guarantor. The guarantor may therefore claim back from the principal debtor whatever sum they have rightfully paid under the guarantee, but not sums paid wrongfully. This right arises from the relationship between the guarantor and the debtor, not from the contract with the creditor.
Right of Contribution Among Co-Guarantors
Section 99 of the Contracts Act 1950 provides that co-sureties for the same debt, in the absence of any contract to the contrary, are liable as between themselves to pay an equal share of the whole debt, or of the part that remains unpaid by the principal debtor. Under section 100, co-sureties who are bound in different sums are liable to pay equally as far as the limits of their respective obligations permit. Where one co-guarantor pays more than their share, they can seek contribution from the others.
This ensures that the burden of the guarantee is shared fairly among all those who agreed to stand behind the debtor's obligation.
Practical Considerations for Business Owners
If you have signed a guarantee, you should be alert to any changes in the underlying arrangement. Request that you be notified of and asked to consent to any variations. Keep records of the original terms you guaranteed.
If you are a creditor holding guarantees, ensure that any indulgences given to debtors are properly documented with the guarantors' written assent. Obtain guarantor consent to material variations in writing.
Understanding these rules can make the difference between a guarantee that remains enforceable and one that has been inadvertently discharged.
