Why It Matters

Why Your Business Needs This Agreement

Oral Guarantees That Are Legally Worthless

The most common guarantee enforcement failure in South Africa occurs when a creditor relies on an oral promise to guarantee a debt. Under Section 6 of the General Laws Amendment Act, this promise is void and completely unenforceable — regardless of the guarantor's clear intention, the number of witnesses, or any partial performance. South African courts have consistently refused to grant equitable relief for oral guarantees, including in cases where the guarantor admitted making the promise. The financial impact of this statutory trap can be catastrophic: a landlord who accepted a verbal guarantee from a director for a R2 million lease is left with zero recourse when the tenant company defaults and the director denies liability.

Guarantee Released by Undisclosed Changes to the Principal Debt

Under South African common law, a material alteration to the principal obligation releases the surety unless the guarantee contains continuing guarantee provisions covering the specific type of change. Creditors who increase the debtor's credit limit, extend the repayment period, release co-sureties, or amend the underlying agreement without the guarantor's knowledge may discover that the guarantee has been inadvertently released. The guarantor successfully raises the material alteration defence, and the creditor loses their security at precisely the moment they need it most. This is one of the most frequently litigated guarantee disputes in South African courts.

NCA Affordability Assessment Not Conducted on Personal Guarantors

Creditors who accept personal guarantees from directors or individuals to secure NCA-regulated credit agreements without conducting an affordability assessment on the guarantor risk having the guarantee declared reckless under Section 83 of the NCA. A court can suspend the guarantee or set it aside entirely if the guarantor demonstrates they could not afford the guaranteed obligation. This NCA trap catches creditors unaware because they treat the guarantee as a separate security instrument rather than recognising it as an "incidental credit agreement" under Section 8(5) that triggers its own NCA compliance requirements.

Corporate Guarantees Ultra Vires the Guarantor Company

A guarantee given by a company that is ultra vires (beyond the company's capacity or objects) or given without the required board authorisation under Section 45 of the Companies Act is unenforceable against the company. The creditor who relied on the corporate guarantee discovers — typically during enforcement proceedings — that the company's MOI does not permit the provision of guarantees, that no board resolution was passed, or that the signatory lacked authority. The guarantee is set aside, and the creditor is left without security. This risk is particularly acute for guarantees within corporate groups, where Section 45 requires specific board approval and a solvency and liquidity test for financial assistance to related companies.

Excussion Defence Adding 12-18 Months to Enforcement

A guarantor who has not renounced the benefit of excussion can insist that the creditor first sue the principal debtor, obtain judgment, and attempt to execute against the debtor's assets before claiming against the guarantor. In the South African court system, this process takes 12-18 months — during which the creditor's losses from non-payment continue to accumulate, interest approaches the in duplum ceiling, and the debtor's assets may be depleted or concealed. The excussion defence is a legitimate common law protection, but its practical effect is to delay and frustrate enforcement. Commercial guarantees must renounce this defence to serve their purpose as quick, reliable security.

What is a Guarantee Agreement?

A Guarantee Agreement is one of the most powerful and widely used credit security instruments in South African commercial practice. At its core, a guarantee creates a binding obligation for a third party (the guarantor) to perform the obligations of a principal debtor if the debtor fails to do so — giving the creditor recourse beyond the debtor's own assets and significantly reducing the risk of non-payment or non-performance. In South Africa, guarantees are pervasive in commercial lending, property leasing, construction contracts, supply agreements, and government procurement — virtually any transaction where a creditor needs additional assurance that the obligations will be fulfilled.

The most critical legal requirement for guarantees in South Africa is Section 6 of the General Laws Amendment Act 50 of 1956, which mandates that any contract of suretyship — or any contract whereby a person undertakes to answer for the debt, default, or miscarriage of another — must be in writing and signed by the surety or guarantor. An oral guarantee is void and completely unenforceable, without exception. The Supreme Court of Appeal has upheld this requirement consistently, including in Fourlamel (Pty) Ltd v Maddison, confirming that no equitable relief is available to a party who relies on an oral guarantee. This statutory requirement makes the form of the guarantee as important as its substance — a guarantee that fails to meet the Section 6 formality requirements is worthless, regardless of the guarantor's clear intention to be bound.

South African law draws a critical distinction between different types of guarantee structures, each with different legal consequences. A conditional guarantee (or traditional suretyship) is an accessory obligation — the guarantor's liability depends on the continued existence and enforceability of the principal debt, and the guarantor can raise any defence available to the principal debtor. A demand guarantee (or independent guarantee) is an abstract obligation — the guarantor must pay on the creditor's first written demand, without the creditor having to prove the debtor's default, and the guarantor cannot raise defences based on the underlying transaction. Performance guarantees (common in construction and procurement) guarantee the debtor's performance of non-monetary obligations, while bank guarantees are demand guarantees issued by registered banks and represent the highest form of commercial security because banks invariably honour valid demands.

This template addresses every type of guarantee used in South African commerce, with provisions specifically designed for our legal framework. It covers the critical distinction between accessory and independent guarantees, the comprehensive renunciation of common law defences (excussion, division, cession of actions), the co-principal debtor clause that strips the guarantor of surety-specific defences, the continuing guarantee provisions that survive changes to the underlying obligation, and the specific challenges posed by business rescue proceedings under Chapter 6 of the Companies Act 71 of 2008 — where the moratorium on proceedings against the principal debtor does not extend to independent guarantors.

The template also addresses the increasingly important intersection of guarantees with the National Credit Act 34 of 2005. Where a guarantee secures a credit agreement that falls within the NCA, the guarantee itself may constitute an "incidental credit agreement" under Section 8(5), triggering NCA compliance requirements including affordability assessments for natural person guarantors. This NCA dimension is frequently overlooked in South African commercial practice, creating enforcement risks that surface only when the creditor attempts to call on the guarantee.

Section 6 of the General Laws Amendment Act 50 of 1956 requires all guarantees to be in writing and signed by the guarantor — an oral guarantee is void, with no equitable exceptions, as confirmed in Fourlamel (Pty) Ltd v Maddison

A guarantee securing a NCA-regulated credit agreement may constitute an "incidental credit agreement" under Section 8(5), triggering affordability assessment requirements for natural person guarantors

The business rescue moratorium under Section 133 of the Companies Act does not extend to independent guarantors — creditors can claim under the guarantee while the debtor is under business rescue protection

A co-principal debtor clause combined with renunciation of excussion allows the creditor to claim directly against the guarantor, eliminating the 12-18 month delay that excussion procedures impose in South African courts

Corporate guarantees under Section 45 of the Companies Act require board approval and a solvency/liquidity test — guarantees given without proper authorisation may be ultra vires and unenforceable

Template Contents

Key Clauses Included

This Guarantee Agreement template covers 12 essential sections, each drafted by South African attorneys.

01

Guarantee Structure & Classification

Defines whether the guarantee is structured as a conditional guarantee (accessory to the principal debt, requiring proof of the debtor's default before the guarantor is liable), a demand guarantee (independent of the underlying obligation, payable on the creditor's first written demand without proof of default), or a performance guarantee (securing the debtor's non-monetary obligations such as construction milestones or service delivery). Each structure has fundamentally different legal consequences under South African law — the choice determines the guarantor's available defences, the creditor's enforcement process, and the guarantee's survival in business rescue proceedings.

02

Guaranteed Obligations & Scope

Precisely identifies the obligations guaranteed — whether limited to a specific transaction or debt, covering all present and future obligations of the debtor to the creditor, or extending to a defined maximum amount with or without interest and costs. The scope determination is critical: a guarantee covering "all amounts owing" by the debtor creates open-ended exposure for the guarantor, while a guarantee limited to a specific agreement and capped at a specified amount provides certainty. The section also addresses whether the guarantee extends to obligations arising from renewals, extensions, and amendments of the underlying agreement.

03

Maximum Guaranteed Amount & Monetary Cap

Specifies the cap on the guarantor's total liability, whether the guarantee covers interest and costs in addition to the principal obligation, the treatment of payments received from the principal debtor (do they reduce the guaranteed amount?), escalation provisions that increase the cap in line with the underlying obligation's growth, and the critical distinction between a cap on the guarantee amount and a cap on the guarantor's total exposure (which may include interest, legal costs, and collection charges above the cap). Without a clear monetary cap, the guarantor's exposure is unlimited — a risk that discourages creditworthy guarantors from providing security.

04

Demand & Payment Mechanics

Establishes the process for calling on the guarantee: for demand guarantees, the creditor delivers a written demand in the prescribed form, and the guarantor must pay within the specified timeframe (typically 7-14 business days) without requiring proof of default. For conditional guarantees, the creditor must prove the debtor's default by providing specified documentation (copy of the unpaid invoice, evidence of demand on the debtor, certificate of indebtedness). The section covers multiple and partial demands, the currency of payment, and the creditor's right to make successive demands up to the guaranteed amount.

05

Co-Principal Debtor & Defence Renunciation

The co-principal debtor clause binds the guarantor not merely as surety but as co-principal debtor in solidum with the principal debtor. This dual capacity is critically important: as a surety, the guarantor can raise numerous common law defences; as a co-principal debtor, these defences are stripped away. The section includes comprehensive renunciation of: the benefit of excussion (beneficium ordinis seu excussionis) — requiring the creditor to exhaust remedies against the debtor first; the benefit of division (beneficium divisionis) — sharing liability among co-guarantors; and the benefit of cession of actions (beneficium cedendarum actionum) — requiring the creditor to cede its rights to the guarantor upon payment.

06

Continuing Guarantee & Survival

Ensures the guarantee remains in force despite changes that would otherwise release a surety under common law. The continuing guarantee provisions address: increases in the principal debt (rent escalation, additional drawdowns), extensions of the payment terms or maturity date, release of co-guarantors or co-sureties, amendments to the underlying agreement, granting of time or indulgences to the debtor, and the creditor's failure to enforce against the debtor timeously. Without these provisions, any material change to the underlying obligation could release the guarantor — a frequently litigated issue in South African commercial law.

07

Subrogation & Recovery Rights

Defines the guarantor's rights after paying under the guarantee: the right of subrogation (stepping into the creditor's shoes and acquiring all rights the creditor had against the debtor, including security interests), the right of recourse (claiming reimbursement from the debtor for the amount paid), and the right of contribution (claiming proportionate reimbursement from co-guarantors). Critically, the section addresses the anti-competition provision — preventing the guarantor from exercising subrogation or recovery rights against the debtor while any amounts remain outstanding to the creditor, ensuring the creditor is fully satisfied before the guarantor competes for the debtor's assets.

08

Release, Expiry & Discharge

Specifies when the guarantee terminates: full and final payment of all guaranteed obligations (not merely partial payment), expiry of a defined guarantee period (common in performance guarantees where the guarantee expires on project completion), written release by the creditor, or discharge by operation of law. Addresses the effect of the debtor's business rescue plan or compromise on the guarantee — and whether the guarantee survives the compromise or is released to the extent of the debtor's reduced liability. Also covers the process for returning the original guarantee document upon discharge.

09

Formalities & Writing Requirement

Ensures compliance with the General Laws Amendment Act Section 6 by confirming the guarantee is in writing and signed by the guarantor (or their duly authorised representative). Covers the specific requirements for corporate guarantors: board or shareholder resolution authorising the guarantee, verification that the guarantee falls within the company's capacity under its MOI, and confirmation that the signatory has authority to bind the entity. For trust guarantors: trustee resolution and verification that the trust deed permits the provision of guarantees. These formality provisions are not merely procedural — failure to comply renders the guarantee void.

10

Business Rescue & Insolvency Provisions

Addresses the complex interaction between guarantees and the debtor's business rescue or insolvency. The Section 133 moratorium in business rescue prevents the creditor from suing the debtor, but it does not extend to an independent guarantor — the creditor can proceed against the guarantor even while the debtor is under business rescue protection. However, if the business rescue plan compromises the principal debt, the impact on the guarantee depends on its structure: an independent demand guarantee survives the compromise, while an accessory suretyship may be partially released. The section also addresses the guarantor's position in the debtor's liquidation and the guarantor's right to prove a claim in the insolvent estate after paying the creditor.

11

NCA Compliance & Incidental Credit

Where the guarantee secures a credit agreement regulated by the National Credit Act, the guarantee itself may constitute an "incidental credit agreement" under Section 8(5) of the NCA. This triggers additional requirements: if the guarantor is a natural person, the credit provider must conduct an affordability assessment before accepting the guarantee, and the guarantee must comply with the NCA's prescribed forms and disclosure requirements. Failure to comply can render the guarantee unenforceable — a trap that many South African creditors fall into by treating the guarantee as a standalone security instrument without considering its NCA implications.

12

Dispute Resolution & Governing Law

Specifies that the guarantee is governed by the laws of the Republic of South Africa, establishes the dispute resolution process (typically aligned with the underlying agreement's provisions), and includes domicilium citandi et executandi for the creditor and guarantor. The section also addresses the guarantor's consent to the jurisdiction of the relevant court, acknowledgement provisions (the guarantor acknowledges the amount owing, which can serve as provisional sentence in South African court proceedings), and the costs provision (typically on an attorney-and-client scale, meaning the losing party pays the winning party's actual legal costs, not just the taxed party-and-party costs).

Legal Compliance

South African Law Compliance

General Laws Amendment Act

General Laws Amendment Act 50 of 1956

Section 6 is the foundational statutory requirement for guarantees in South Africa. It provides that no contract of suretyship — and no contract whereby a person undertakes to answer for the debt, default, or miscarriage of another person — shall be valid unless the terms are embodied in a written document signed by the surety or the person undertaking the obligation. The Supreme Court of Appeal has confirmed in Fourlamel (Pty) Ltd v Maddison and numerous subsequent decisions that Section 6 is peremptory: no equitable relief, estoppel, or part performance can save an oral guarantee. The writing must contain the material terms — identification of the parties, the obligations guaranteed, and the guarantor's signature. Electronic signatures comply with Section 6 provided they meet the requirements of the Electronic Communications and Transactions Act 25 of 2002.

NCA

National Credit Act 34 of 2005

Section 8(5) of the NCA provides that a guarantee in respect of a credit facility or credit transaction constitutes an "incidental credit agreement". Where the underlying debt is a NCA-regulated credit agreement and the guarantor is a natural person, the NCA requirements apply to the guarantee — including affordability assessments, disclosure obligations, and enforcement procedures (Section 129 notice). The NCA also imposes reckless lending provisions under Section 81: if the credit provider knew or ought to have known that the guarantor could not afford the guaranteed obligation, the guarantee may be declared reckless and suspended or set aside. This intersection of guarantee law and consumer credit legislation is one of the most complex and frequently misunderstood areas of South African commercial law.

Companies Act

Companies Act 71 of 2008

Chapter 6 governs business rescue proceedings and has significant implications for guarantees. When the principal debtor enters business rescue, the Section 133 moratorium prevents legal proceedings against the debtor — but does not extend to independent guarantors. The creditor can proceed against the guarantor immediately, without waiting for the business rescue process to conclude. If the business rescue plan compromises the principal debt, the effect on the guarantee depends on its structure: the Supreme Court of Appeal in ABSA Bank v Caine held that a demand guarantee structured as an independent obligation survives business rescue, while an accessory suretyship may be partially released to the extent the principal debt is reduced by the plan. The guarantee should expressly address business rescue scenarios to provide certainty.

Insolvency Act

Insolvency Act 24 of 1936

The Insolvency Act governs the treatment of guarantees in the debtor's insolvency. A guarantee is not discharged by the debtor's sequestration or liquidation — the creditor can proceed against the guarantor for the full guaranteed amount. After paying the creditor, the guarantor acquires a right of subrogation and can prove a claim in the insolvent estate as a concurrent creditor. However, the Insolvency Act's voidable disposition provisions (Sections 26-31) may apply to guarantees given by the debtor in favour of a third party's obligations — if the guarantee was given without receiving fair value and within the prescribed period before insolvency, the trustee can set it aside as a disposition without value.

Common Law of Suretyship

South African Common Law of Suretyship and Guarantee

The common law provides the substantive framework for guarantee law in South Africa, supplemented by the General Laws Amendment Act's writing requirement. Key common law principles include: the accessory nature of traditional suretyship (the surety's liability depends on the principal debt), the guarantor's defences (excussion, division, cession of actions, and material alteration of the principal obligation), the strict construction of guarantee terms in favour of the guarantor (ambiguities are resolved against the creditor), and the distinction between suretyship and independent guarantee — an area of ongoing judicial development. The co-principal debtor clause, while contractual in origin, has been consistently upheld by South African courts as an effective mechanism for overcoming the limitations of accessory suretyship.

Simple Process

Create Your Guarantee Agreement in Minutes

Our guided wizard walks you through every clause — no legal knowledge required. Attorney-drafted, South African law compliant.

01

Determine the guarantee type and scope

Decide the appropriate guarantee structure for your transaction — demand guarantee (strongest creditor protection, common for bank guarantees and construction), conditional guarantee (requiring proof of default, more balanced), or performance guarantee (securing non-monetary obligations). Define the scope: which specific obligations are guaranteed, the maximum guaranteed amount, whether interest and costs are included, and the guarantee period.

02

Assess NCA applicability and corporate authority

Determine whether the underlying obligation is a NCA-regulated credit agreement, and if so, whether the guarantee triggers NCA compliance requirements (particularly for natural person guarantors). For corporate guarantors, verify that the guarantee falls within the company's capacity, obtain a board resolution under Section 45 of the Companies Act, and confirm the signatory's authority.

03

Customise the template for your transaction

Complete the template by selecting the guarantee type, inserting the guaranteed obligations and monetary cap, choosing the appropriate defence renunciation provisions, specifying the demand and payment mechanics, and adding the continuing guarantee provisions to cover anticipated changes to the underlying obligation. Ensure the guarantee references the specific underlying agreement by date, parties, and obligation.

04

Review for legal compliance and Section 6 formalities

Verify compliance with the General Laws Amendment Act Section 6 writing requirement, ensure all material terms are clearly stated, confirm the NCA requirements are addressed (affordability assessment for natural person guarantors), check the corporate authority documentation (board resolution, MOI capacity), and verify consistency with the underlying agreement. Engage legal counsel for guarantees securing large or complex obligations.

05

Execute and secure the guarantee document

Have the guarantor sign the guarantee in the presence of witnesses. For corporate guarantors, attach the certified board resolution as proof of authority. Store the original guarantee securely with the underlying agreement. Provide copies to all parties. For bank guarantees, follow the issuing bank's procedures for activation and lodgement. Note the guarantee terms, monetary cap, and expiry date in the creditor's security register and diarise renewal or expiry dates.

Common Questions

Frequently Asked Questions

A Guarantee Agreement is a contract in which a third party (the guarantor) undertakes to fulfil the obligations of a principal debtor if the debtor fails to do so. It is one of the most widely used credit security instruments in South African commercial practice — used in lending, leasing, construction, supply agreements, and government procurement. Under Section 6 of the General Laws Amendment Act 50 of 1956, a guarantee must be in writing and signed by the guarantor to be enforceable — an oral guarantee is void, without exception. The guarantee works by creating a secondary (or in the case of demand guarantees, an independent) obligation that gives the creditor recourse against the guarantor's assets if the debtor defaults. The creditor can claim from the guarantor directly (if the guarantee includes a co-principal debtor clause and renunciation of excussion), without first having to sue or exhaust remedies against the principal debtor.
