Prescription of Debt in South Africa: When Can a Creditor No Longer Sue? [2026]

What “prescription” means

A creditor’s right to enforce a debt does not last forever. Extinctive prescription is the rule that, after a set period of inaction, a valid debt is extinguished — the creditor loses the right to recover it through the courts. The policy is simple: claims should be pursued while evidence is fresh and witnesses available, and debtors should not live indefinitely under the threat of stale demands.

The governing statute is the Prescription Act 68 of 1969. Its core rule is in section 10:

Note the word extinguished. In South African law prescription does more than bar the remedy — it destroys the debt itself. That is why a debtor can safely refuse to pay a prescribed debt, and why the consumer protections in the National Credit Act can bite as soon as the debt is extinguished, before any court has ruled on it.

The prescription periods at a glance

Section 11 sets four periods. The default is three years; longer periods apply to the special categories listed below. The exact words matter, because the longest applicable category wins:

• Three years (s 11(d)) — the catch-all. Ordinary contracts, money lent and advanced, unpaid trade accounts, professional fees and loan claims, as well as delictual damages claims.
• Six years (s 11(c)) — bills of exchange, promissory notes and other negotiable instruments, and debts under a notarial contract.
• Fifteen years (s 11(b)) — a State loan, or a sale or lease of land by the State.
• Thirty years (s 11(a)) — a debt secured by a mortgage bond, a judgment debt, and tax debts. This is why a creditor will often sue to judgment: a three-year claim, once it becomes a judgment debt, gets a fresh thirty-year life.

A debt secured over movables by a notarial bond is not automatically a thirty-year “mortgage bond” debt — the thirty-year category in s 11(a)(i) speaks of a debt secured by a mortgage bond. The classification of the underlying debt is what fixes the period, so always test the security and the obligation together.

When the clock starts: a debt that is “due”

A period is no use without a starting date. Section 12 supplies it: prescription runs from the moment the debt becomes due, subject to a crucial knowledge qualification.

What does “due” mean? The leading authority is Truter and Another v Deysel, where the SCA tied it to having a complete cause of action — the whole bundle of facts the creditor must prove to win. A medical-negligence plaintiff there argued prescription only ran once he obtained an expert report confirming negligence; the SCA rejected that, holding that legal conclusions like negligence are not facts that delay the running of prescription.

The practical lesson cuts both ways. A creditor cannot sleep on a claim and then plead ignorance if reasonable diligence would have revealed it. But a debt that is genuinely not yet enforceable — for example, a loan repayable only “on demand” where demand is a condition, or an amount payable on a future date — does not start prescribing until it is actually due and payable.

What counts as a “debt” that can prescribe

Prescription only extinguishes things that are “debts”. The Act does not define the word, so its meaning has been settled by the courts — and the answer matters, because some claims escape prescription entirely. In Makate v Vodacom (Pty) Ltd the Constitutional Court held that “debt” must be read in the way least intrusive on the constitutional right of access to courts, and that a claim to enforce an agreement to negotiate in good faith was not a debt that could prescribe.

A year later, in Off-Beat Holiday Club v Sanbonani Holiday Spa Shareblock Ltd, the Constitutional Court applied Makate and adopted the narrow dictionary meaning of “debt”, holding that a statutory remedy — the right to ask a court to determine a dispute — is not a debt and does not prescribe:

The line, in short: an obligation to pay money or deliver goods or services is a debt and prescribes; a right to ask a court for a declaration or a statutory remedy usually is not. If your claim is to compel performance of an obligation, assume the three-year clock is running unless a longer category in s 11 applies.

Stopping or restarting the clock

Prescription can be interrupted in two ways before it completes — and an interruption is powerful, because it generally resets the period to zero. The first is the debtor’s own acknowledgement of the debt.

An acknowledgement may be express (a signed acknowledgement of debt, a written admission, a request for indulgence) or tacit (a part-payment, an offer to pay in instalments). The effect is dramatic: the old time falls away and a fresh three-year period begins. In KLD Residential CC v Empire Earth Investments 17 (Pty) Ltd the SCA recognised a limited exception to the “without prejudice” rule so that even an acknowledgement made during settlement talks can be used to prove interruption:

The second route is judicial interruption — serving legal process that claims payment. Issuing a summons is not enough; it must be served on the debtor:

When completion of prescription is delayed

Separate from interruption, section 13 delays the completion of prescription where a listed impediment exists. It does not reset the clock; instead, where one of the impediments applies and the period would otherwise finish during it or soon after, completion is held off until one year after the impediment falls away. The impediments include that the creditor is a minor or under a disability or curatorship; that the debtor is outside the Republic; that creditor and debtor are married to each other or are partners as to a partnership debt; that the debt is the subject of arbitration; or that it is the object of a claim filed against a deceased or insolvent estate or a company in liquidation.

These are narrow, fact-specific safety valves. The headline rule for most commercial debts remains the plain three-year period running from the date the debt became due.

Prescription must be pleaded — a court cannot raise it

A debt may have prescribed and yet still be enforced, because of a procedural rule that surprises many debtors: a court will not raise prescription for you. The debtor must plead it.

The consequence is real: in ordinary civil litigation a creditor can take default judgment on a debt that has in fact prescribed, simply because the debtor did not turn up or did not plead the defence. That is exactly the mischief the National Credit Act set out to cure for consumer-credit debts — discussed next.

The NCA twist: section 126B and prescribed consumer debt

For debts under a credit agreement to which the National Credit Act applies, Parliament went well beyond the Prescription Act. Section 126B — inserted into the NCA by the National Credit Amendment Act 19 of 2014 and in force from 13 March 2015 — makes it unlawful to sell, continue collecting, or re-activate a debt under a credit agreement that has already been extinguished by prescription. Critically, the prohibition bites even where the consumer has not raised, or did not know to raise, the defence of prescription. That reverses the ordinary s 17 position for consumer credit: the credit provider, not the consumer, bears the risk of a prescribed debt.

Section 126B was inserted by the 2014 Amendment Act, so it does not appear in the principal National Credit Act 34 of 2005 text — read the consolidated NCA for the current numbering, and see our enforcement and unlawful-agreements spoke for how this is applied.

The reach of s 126B therefore depends entirely on a prior question: is the debt a credit agreement to which the NCA applies at all? If it is not — for example, a large business loan above the thresholds — then s 126B offers no protection, and only the ordinary Prescription Act regime (including the s 17 pleading rule) governs.

Does the NCA even apply? Substance over form and the thresholds

The firm’s anchor authority on NCA application is The Profit Hub (Pty) Ltd v Zuwon Consultants (Pty) Ltd. It holds that whether an agreement is a credit agreement is decided by its substance, not its form — the Act says so in section 8 — read through the text-context-purpose method of Endumeni:

But the substance enquiry is only the first gate. Even a genuine loan escapes the NCA where a threshold exclusion applies. Two matter most for business debt: the juristic-person exemption (a company consumer whose asset value or turnover equals or exceeds the determined threshold), and the large-agreement exclusion:

So Profit Hub matters for prescription in a precise way. A business debt above the R1 000 000 / R250 000 thresholds falls outside the NCA entirely. For that debtor, s 126B offers no shield: prescription still extinguishes the debt after three years, but it must be pleaded (s 17), and the facts of Profit Hub — an acknowledgement of debt and suretyships — show how readily a creditor can interrupt or fortify a claim under s 14. A consumer credit debt, by contrast, gets the full s 126B protection.

Practical checklist for creditors and debtors

Prescription rewards diligence and punishes delay. A short discipline for each side:

If you are a creditor:

• Diarise the due date and the three-year deadline the moment a debt arises. Sue, or take a fresh signed acknowledgement of debt, well before it.
• Remember that a part-payment or written admission interrupts and restarts the clock (s 14) — capture and date every such acknowledgement.
• If you litigate, serve the process (not merely issue it) to interrupt judicially under s 15, then prosecute it to judgment so the interruption does not lapse.
• Once you have judgment, the debt becomes a thirty-year judgment debt (s 11(a)).

If you are a debtor:

• Prescription must be pleaded — a court will not raise it for you (s 17). Always check the dates before admitting any old debt.
• Do not casually acknowledge or part-pay an old debt: under s 14 that can restart a clock that may already be near completion.
• For a consumer-credit debt that has prescribed, the credit provider may not collect or re-activate it at all (NCA s 126B) — even if you did not know to plead prescription.
• Where you stood surety, check whether the principal debt has prescribed: under s 10(2) that usually releases you too.

Enforcement ceilings run alongside prescription. Even where a debt is still live, the common-law in duplum rule caps unpaid interest at the outstanding capital, and in Paulsen v Slip Knot Investments the Constitutional Court confirmed that cap keeps operating even after litigation begins. Prescription decides whether a creditor can still sue; in duplum limits how much can be recovered.
