Loans, Suretyships & Acknowledgements of Debt in South African Law [2026]

Loans, suretyships and AODs: why the NCA question comes first

Most South African businesses raise money the same handful of ways: a term loan or facility from a bank or private financier; a shareholder or director loan; bridging or receivables finance. Whatever the source, the lender almost always wants security — a personal suretyship from the owners, a cession of book debts, a notarial or mortgage bond — and, when payment is in trouble, a signed acknowledgement of debt (AOD) confirming what is owed and how it will be repaid.

The single most important question for any of these instruments is whether the National Credit Act applies. If it does, the lender usually has to be a registered credit provider, and the agreement has to comply with the Act’s disclosure, affordability and interest-cap rules. Get it wrong — lend as an unregistered credit provider when registration was required — and the agreement can be unlawful and void, which means the lender may recover nothing. The stakes are high enough that characterisation should be settled before the ink dries, not litigated afterwards.

Substance over form: classifying the instrument under s 8

The Act does not let parties dodge regulation by choosing a clever label. Section 8 decides what an agreement is “irrespective of its form”, and the courts interpret it on the now-standard triad of text, context and purpose. There are three species of credit agreement: a credit facility (s 8(3) — the revolving, draw-as-you-need structure of a store account or credit card), a credit transaction (s 8(4) — which includes a secured loan, instalment or discount transaction, and, via the s 8(4)(f) catch-all, an ordinary loan for a charge) and a credit guarantee (s 8(5) — into which a suretyship falls, but only where the underlying agreement is itself regulated):

This was the heart of The Profit Hub v Zuwon. The financier had styled its deal as an invoice “discounting” agreement with an out-and-out cession of the invoices. But because the client had to repay the advance plus a 13% factoring fee whether or not its debtors paid, with suretyships as security, the SCA held the deal was in substance a loan — the cession was security, not a sale. The court set out the controlling test:

A loan that is a credit transaction is governed by s 8(4), the catch-all of which sweeps in “any other agreement” under which payment is deferred for a charge, fee or interest. The Act’s own words:

Two practical points follow. First, the “charge, fee or interest” requirement is the common thread of every credit agreement: in Asmal v Essa the SCA held that an interest-free, friendly loan with no quantified charge is not a credit agreement and falls outside the Act altogether. Second, a fixed once-off loan is a credit transaction, not a credit facility — a distinction that was decisive in Profit Hub.

(Norman AJA, concurring in the result, would have held the deal was a credit facility, likening the deferred repayment and penalty charges to a store or credit card. The point did not change the outcome, but it shows how finely balanced classification can be — another reason to characterise a deal deliberately at the drafting stage. The same analysis is worked through in our note on invoice discounting vs loans.)

The threshold exclusions: the R1m and R250 000 carve-outs

Even where an agreement is a credit agreement, the Act can be switched off entirely by the threshold exclusions in s 4(1). They are the reason so many ordinary business loans and suretyships sit outside the NCA. Two exclusions matter most:

• The juristic-person threshold (s 4(1)(a)(i)). The Act does not apply where the consumer is a juristic person (a company, close corporation or trust with three or more trustees) whose asset value or annual turnover, with related juristic persons, equals or exceeds the threshold set by the Minister — currently R1 000 000.
• The large-agreement carve-out (s 4(1)(b) read with s 9(4)). Even below R1m, a juristic-person consumer is excluded for a large agreement — a mortgage, or a non-mortgage credit transaction whose principal debt is at or above R250 000.

In Profit Hub, the loan ultimately escaped the Act not because it was a discount (it was not), but because of these thresholds. The SCA stated the figures directly:

A crucial caveat: a natural-person borrower — a sole proprietor in their own name, or an individual borrowing personally — gets no threshold exclusion. For natural persons the Act applies regardless of the loan size, so a private lender to an individual almost always has to be registered and NCA-compliant. The thresholds protect the deal only when the borrower is a juristic person.

Shareholder, director and family loans: the “arm’s length” exclusion

Section 4(1) applies the Act only to credit agreements “between parties dealing at arm’s length”. Section 4(2)(b) then deems certain relationships not to be at arm’s length, so the Act simply does not reach them. This is the basis on which intra-group and family lending usually sits outside the NCA:

So a loan from a controlling shareholder to their company, a loan from the company back to that shareholder, and a genuine loan between dependent family members are not arm’s-length credit agreements and fall outside the Act. That does not make them risk-free — a director’s loan can raise trust, tax and Companies Act issues, and a poorly papered family loan can still prescribe or be disputed — but the NCA registration and compliance machinery does not apply.

Compulsory registration — and the cost of getting it wrong

If a loan is a credit agreement and no exclusion takes it out, the lender must be registered. A person must apply to register as a credit provider where the total principal debt owed to it exceeds the threshold prescribed under s 42(1) — and since 11 May 2016 that threshold has been nil. The Minister’s notice reduced the old R500 000 trigger to zero:

The penalty for non-registration is severe. Under s 40(4) of the Act, a credit agreement entered into by a credit provider who was required to register but who was not registered is an unlawful agreement and void to the extent provided for in section 89. A void agreement under s 89 means the lender generally cannot recover what it advanced: a court must order the agreement void from the outset and the provider to refund the consumer (s 89(5)(a)–(b)). The Act’s original power to order the advance forfeited to the State (s 89(5)(c)) was struck down as unconstitutional in National Credit Regulator v Opperman [2012] ZACC 29, so there is no payment to the State. The full mechanics, and the room courts have to do what is just and equitable, are covered in unlawful and unregistered credit agreements.

Suretyships: the writing-and-signature formality (s 6)

A suretyship is the workhorse of business lending: the owners, in their personal capacity, guarantee the company’s debt. In Profit Hub the surety, Mr Ndawonde, bound himself “as surety and co-principal debtor” and was held jointly and severally liable for the full judgment. But a suretyship is only worth anything if it is valid — and validity turns on a strict statutory formality.

Section 6 has two requirements: the suretyship must be in writing and it must be signed by or on behalf of the surety. A purely oral suretyship is void. Because s 6 requires the terms of the suretyship to be “embodied in a written document”, the courts have long read it to require that those terms be ascertainable from the document itself — the identity of the creditor, the surety, the principal debtor and the nature and amount of the principal debt (the settled interpretation in Sapirstein v Anglo African Shipping Co (SA) Ltd 1978 (4) SA 1 (A) and Fourlamel (Pty) Ltd v Maddison 1977 (1) SA 333 (A)). A suretyship from which the principal debt or debtor cannot be identified risks being held invalid.

Three drafting traps recur. (1) The unidentified principal debt. A suretyship for “all amounts owing” must still make the principal debtor and the underlying obligation ascertainable. (2) The wrong or missing signature. Where a surety signs on behalf of a company, authority must exist; a director who signs personally where the company was meant to be surety (or vice versa) can bind the wrong party or no one. (3) Variation without re-signing. A material change to the principal debt can release the surety unless the suretyship anticipates it. These are exactly the kind of issues a tailored credit agreement and suretyship, drafted together, avoid.

Acknowledgements of debt: drafting for enforceability

An acknowledgement of debt is a written admission by the debtor of what is owed, usually coupled with a repayment plan. In Profit Hub, Zuwon and Mr Ndawonde signed exactly that — a written AOD and security agreement acknowledging the debt and agreeing to pay by instalments. A well-drafted AOD does several useful things at once: it fixes the amount (removing a debtor’s later dispute about quantum), it can carry a consent to judgment for speedy enforcement, and — importantly — it interrupts prescription and starts the three-year clock running afresh.

There is a characterisation trap, though. An AOD that does no more than admit a pre-existing debt is not itself a credit agreement. But the moment an AOD defers payment and adds a charge, fee or interest for that deferral, it can become a credit transaction under s 8(4)(f) — and if it is one, the NCA’s registration, disclosure and affordability rules apply to it. As Asmal v Essa confirms, the dividing line is whether a “charge, fee or interest” is payable for the use of the credit. An AOD restructuring a consumer’s debt with new interest should be drafted with the NCA squarely in mind.

Penalty, default and acceleration clauses

Loan and AOD documents bristle with default machinery: acceleration (the whole balance falls due on a missed instalment), default interest at a punitive rate, forfeiture of deposits, and “agreed” legal costs. In Profit Hub the agreements carried an 8%-per-month penalty and attorney-and-client costs, and the SCA enforced them. These stipulations are governed by the Conventional Penalties Act 15 of 1962, which first makes them enforceable:

The vital counterweight is section 3. A court may reduce a penalty it finds out of proportion to the creditor’s actual prejudice — a discretion that applies even where the debtor freely signed:

The practical lesson cuts both ways. A creditor should set default charges that are a genuine pre-estimate of loss, not a windfall, or risk having them cut down. A debtor faced with a crushing penalty has a real statutory remedy. And where the loan is a credit agreement, the in duplum rule and the NCA caps cap default interest independently of the Conventional Penalties Act.

Interest on debt and the prescription clock

Two time-and-money rules govern every loan and AOD. First, interest. Where the parties have not validly agreed a rate (and outside the NCA caps), a money judgment carries interest at the prescribed rate under the Prescribed Rate of Interest Act 55 of 1975, currently fixed at:

Second, prescription. An ordinary contractual debt — an unsecured loan or AOD, not embodied in a mortgage bond or a court judgment — is extinguished after three years:

The clock runs from when the debt is due (s 12(1)), and a debt is extinguished — not merely rendered unenforceable — once it prescribes (s 10(1)). That is why a signed AOD is so valuable to a creditor: a written acknowledgement of liability interrupts prescription, starting a fresh three-year period from the date of acknowledgement. A loan that is left to run for years without payment or acknowledgement can quietly prescribe, leaving the creditor with nothing to enforce. The interruption is created by s 14 of the Act:

Security can also be misunderstood here. Where book debts are ceded to a lender as security — not sold — the cession is one in securitatem debiti: the principal debt revests in the cedent when the loan is discharged, and no separate re-cession is needed. That distinction (an outright cession versus a security cession) was the crux of Grobler v Oosthuizen, and it is exactly the distinction the SCA drew in Profit Hub when it held that Zuwon’s ceded invoices were “simply an additional form of security”.

A drafting checklist for business loans, suretyships and AODs

Before signing, work through these questions in order. Each one changes the compliance burden — and the enforceability — of the deal:

1. What is the instrument, in substance? A loan, credit facility, discount or guarantee? Label is irrelevant; the cash-flows and risk decide (s 8; Profit Hub).
2. Is there a charge, fee or interest? An interest-free, uncharged loan is not a credit agreement at all (Asmal v Essa).
3. Who is the consumer? A natural person gets no threshold relief; a juristic person at or above R1m, or one taking a R250 000+ large agreement, is excluded (s 4(1)).
4. Is it arm’s length? Shareholder, director and dependent-family loans fall outside the Act (s 4(2)(b)).
5. If the NCA applies, are you registered and compliant? Registration is now compulsory from the first rand; a missing registration makes the agreement void (ss 40(4), 89).
6. Is every suretyship in writing, signed, and complete? Identify the creditor, surety, principal debtor and principal debt in the document (s 6).
7. Are the penalty and default terms proportionate? A court can reduce an excessive penalty (Conventional Penalties Act s 3); the in duplum rule and NCA caps apply where relevant.
8. Have you protected against prescription? Keep the three-year clock in view; a signed AOD interrupts it (Prescription Act s 14).

Loans, suretyships and AODs look like standard paperwork, but the consequences of a misclassified agreement, an invalid suretyship or a prescribed debt are anything but standard. If you are lending, borrowing or restructuring debt for a business, speak to us before you sign — characterising the deal correctly at the start is far cheaper than litigating it later.
