What is a guarantee?
Is a guarantee enforceable in South Africa?
“This obligation is wholly independent of the underlying contract of sale … Whatever disputes may subsequently arise between buyer and seller is of no moment insofar as the bank’s obligation is concerned. The bank’s liability to the seller is to honour the credit. … The only basis upon which the bank can escape liability is proof of fraud on the part of the beneficiary.”
“A guarantee of the kind under consideration was enforceable according to its terms. The introduction of extraneous issues as a defence is precluded, save for very limited exceptions like fraud.”
When you need a Guarantees
- A contractor must provide a construction or performance guarantee (often a JBCC or FIDIC bond) in favour of the employer before being awarded or commencing the works.
- A buyer, employer or landlord wants security that does not depend on first proving the other party’s breach — a guarantee callable on written demand gives “cash in hand” certainty.
- A bank or short-term insurer is asked to issue a guarantee on behalf of its client (the applicant), backed by a counter-indemnity from that client.
- Cross-border or supply transactions where a beneficiary wants an advance-payment, retention or payment guarantee that operates like an irrevocable letter of credit.
- A holding company or sponsor is asked to give a payment or performance guarantee to support a subsidiary’s obligations under a finance or supply agreement.
What a Guarantees should contain
Independent (autonomous) undertaking
State expressly that the guarantee is a primary, independent obligation — not a suretyship or accessory undertaking — and that the guarantor’s liability is unaffected by disputes under the underlying contract. In Lombard the guarantee said any reference to the underlying agreement was for convenience only, with no intention to create an accessory obligation or suretyship.
The trigger event and conditions of payment
Define precisely what makes the guarantee payable — e.g. a first written demand stating that the contractor is in breach, or an objective event such as liquidation. Because the guarantor pays against conforming documents (not against proof of actual breach), the wording of the trigger is the single most important term.
Demand mechanics and conforming documents
Set out exactly how a valid demand must be made: who may sign it, the wording it must contain, supporting documents (e.g. an architect’s certificate or notice of cancellation), where it must be delivered and by when. A demand that does not strictly conform may be validly rejected.
Guaranteed amount, reductions and expiry
Fix the maximum amount, whether it reduces over time or with progress payments, and a clear expiry date. Demand guarantees are typically capped and time-limited — demands received after expiry are not payable, so the expiry date must align with the project programme.
Fraud exception (and nothing else)
It is good practice to record that payment will be withheld only in the narrow case of established fraud of which the guarantor has notice, mirroring the common-law position. This manages expectations: the applicant cannot block payment merely because it disputes the beneficiary’s entitlement under the underlying contract.
Counter-indemnity from the applicant
A bank or insurer that issues a guarantee almost always takes a back-to-back counter-indemnity from its client (the applicant), entitling it to reimbursement of whatever it pays the beneficiary. This is where the applicant’s real financial exposure sits, and it usually survives the guarantee itself.
Governing law, jurisdiction and assignment
Specify South African governing law and jurisdiction, and whether the beneficiary may cede or assign its rights. For cross-border bonds, address whether the URDG 758 (ICC Uniform Rules for Demand Guarantees) apply, as these fill gaps and standardise demand and expiry mechanics.
Demand guarantee vs suretyship in South African law
| Feature | Demand guarantee | Suretyship |
|---|---|---|
| Nature of liability | Primary and independent of the underlying contract | Accessory — depends on a valid principal debt |
| What triggers payment | A conforming written demand / defined event, on its own terms | The principal debtor’s actual default on the secured debt |
| Affected by the underlying contract dispute? | No — disputes under the underlying contract are irrelevant (Lombard) | Yes — defences and validity of the principal debt flow through |
| Writing requirement (s 6, Act 50 of 1956) | No statutory writing formality applies | Yes — must be in writing and signed by the surety, or it is void |
| Defences available | Essentially only established fraud known to the guarantor | All defences the principal debtor could raise, plus excussion/division |
| Typical issuer | Bank or short-term insurer (against a counter-indemnity) | Director, shareholder, parent company or individual |
Common South African pitfalls
- Assuming you can stop payment because you dispute the underlying contract. Under Lombard and Coface, a demand guarantee is paid on its terms regardless of the merits of the project dispute — only clear, established fraud known to the guarantor will justify an interdict, and the bar for that is very high.
- Calling the document a “guarantee” when the wording actually creates a suretyship (or the reverse). Courts look at substance, not the heading. If your “guarantee” is in truth accessory, it may be void for want of the section 6 writing formality, or carry surety defences you did not expect.
- Sloppy trigger and demand wording. Because the guarantor pays against conforming documents rather than against proof of breach, a vague trigger event, missing signatory authority, or wrong supporting documents can either let a beneficiary call the bond too easily or let the guarantor reject a legitimate demand.
- Overlooking the expiry date and reductions. A demand received one day after expiry is unenforceable, and a guarantee that does not reduce with progress payments can leave the applicant over-secured — align the amount and expiry with the contract programme.
- Underestimating the counter-indemnity. The applicant’s real risk is the back-to-back counter-indemnity to the bank or insurer: once the guarantee is called and paid, the applicant must reimburse the issuer in full, often with little ability to contest the beneficiary’s entitlement.
Frequently asked questions
Is a guarantee enforceable in South Africa?
Yes. A demand (independent) guarantee is enforceable on its own terms in South Africa. The Supreme Court of Appeal in Lombard Insurance v Landmark Holdings held that the guarantor must pay against a conforming demand, wholly independently of the underlying contract, and the only real defence is established fraud known to the guarantor.
What is the difference between a guarantee and a suretyship?
A suretyship is accessory — the surety’s liability depends on a valid principal debt and falls away if that debt is paid or void. A demand guarantee is a primary, independent obligation paid on its own terms regardless of disputes under the underlying contract. South African courts decide which one you have by looking at the substance of the wording, not the title.
Does a guarantee have to be in writing in South Africa?
There is no statutory writing requirement for a guarantee. Section 6 of the General Law Amendment Act 50 of 1956 requires only a suretyship to be in writing and signed. In practice, however, every demand guarantee is reduced to writing because the document’s exact wording determines when and how it must be paid.
Can I stop a bank or insurer paying out a demand guarantee?
Only in very limited circumstances. South African courts will not interdict payment merely because you dispute the underlying contract. You must show clear, established fraud of which the guarantor has notice (Coface; Set Square). Anything less — an ordinary contractual dispute — is not a defence to a conforming demand.
What is a construction or performance guarantee?
It is a demand guarantee used in building and engineering projects, where a bank or insurer undertakes to pay the employer up to a fixed amount if the contractor defaults. Standard JBCC and FIDIC bonds are usually structured as independent, on-demand guarantees, so the employer can call them without first proving the contractor’s breach.
What is the fraud exception to a demand guarantee?
The fraud exception is the single recognised ground on which a guarantor may refuse to pay an otherwise conforming demand. It requires clear, established fraud by the beneficiary of which the guarantor has notice — for example, a demand the beneficiary knows to be false. Mere allegations or an underlying contractual dispute do not meet this strict threshold.
Does the National Credit Act apply to a guarantee?
A guarantee can fall within the National Credit Act 34 of 2005 as a “credit guarantee”, but only to the extent that the Act applies to the underlying credit agreement it supports. A typical demand guarantee or construction bond securing a commercial supply or works contract usually falls outside the NCA, but each arrangement should be assessed on its facts.
Who are the parties to a guarantee?
There are usually three: the applicant (the party at whose request the guarantee is issued, e.g. the contractor), the guarantor (the bank or insurer that issues it), and the beneficiary (the party entitled to demand payment, e.g. the employer). The applicant typically gives the guarantor a counter-indemnity, which is where the applicant’s real liability sits.
