By Kredcor — South Africa’s Commercial Debt Recovery Partners | Registered with the Council for Debt Collectors (Reg Nr 0016365/06) | 26+ Years of Unblemished Experience

The short answer: In South Africa, most commercial debts prescribe — meaning they become legally unenforceable — after three years from the date the debt became due, under the Prescription Act 68 of 1969. Once prescription is complete and the debtor raises it as a defence, you cannot recover that debt through legal action. But here’s the critical part most credit managers miss: prescription can be interrupted and reset — if you know how.

This is not a technicality you can afford to ignore. Our team at Kredcor has seen countless businesses lose tens of thousands of rands simply because they waited too long, didn’t document properly, or didn’t know what actions stop the clock. This 2026 update gives you everything you need to stay on the right side of this law.

1. What Is Prescription of Debt in South Africa?

Prescription of debt in South Africa is the legal process by which a debt becomes extinguished — wiped out — because too much time has passed without the creditor taking action or the debtor acknowledging liability. It is governed by the Prescription Act 68 of 1969, one of the most practically important statutes for any business that extends credit.

Think of it as a legal time bomb. The clock starts ticking the moment a debt becomes due. If you don’t interrupt it in time, the debt dies — and you have no legal recourse to recover it, even if the debtor clearly owes you the money.

“Prescription does not erase the existence of the debt itself; it simply renders it unenforceable through legal means.” — A fundamental distinction every credit manager must understand.

In our 26 years of commercial debt recovery, we have found that prescription is one of the top three reasons businesses lose money they should have recovered. It is entirely preventable — but only if you understand how it works.

2. The Prescription Periods You Need to Know (2026)

Under the Prescription Act, the period depends on the type of debt. Here is a practical summary for business creditors:

Type of Debt	Prescription Period
Most commercial debts (invoices, trade credit, services)	3 years
Debt arising from a bill of exchange or notarial contract	6 years
Mortgage bonds and judgment debts	30 years
Debt owed to the State (advance or loan)	15 years
State debts (taxes, royalties, etc.)	30 years

For the vast majority of SMEs, credit managers, and financial managers reading this — the three-year rule is the one that matters most day to day. If you extend trade credit and an invoice goes unpaid, your clock starts that day.

As at the date of this 2026 update, there have been no legislative amendments changing these core prescription periods since the Act was last amended in December 2020 (relating to sexual offences — irrelevant to commercial debt). The three-year period for ordinary commercial debt remains firmly in place.

3. When Does the Clock Start Ticking?

This is where most businesses get tripped up. Prescription of debt in South Africa does not simply start from the invoice date. Section 12 of the Prescription Act is clear:

Prescription begins to run as soon as the debt is due.

And a debt is only deemed “due” when the creditor has knowledge of:

The identity of the debtor; and
The facts from which the debt arises.

Importantly, if the debtor wilfully prevents the creditor from becoming aware of the debt’s existence, prescription does not begin to run until the creditor gains awareness.

Practical implications for your credit department:

If your payment terms are 30 days, the clock generally starts on day 31 — not the invoice date.
If a debtor hides their identity or the nature of the dispute, the clock may be paused.
If you have an acceleration clause in your agreement (where the full balance becomes due upon default), the wording of that clause determines exactly when prescription starts — a detail our team scrutinises carefully on every account.

The landmark case of Standard Bank of South Africa Ltd v Miracle Mile Investments 67 (Pty) Ltd confirmed that the commencement of prescription under acceleration clauses depends entirely on the specific contractual wording. Get your credit agreements checked. It matters more than you think.

4. What Interrupts (Resets) Prescription?

Interrupting prescription is the single most important defensive action a creditor can take. When prescription is interrupted, the clock resets to zero — you get a fresh three years.

Prescription of debt in South Africa is interrupted by:

A) Service of legal process. Issuing and serving a summons on the debtor formally interrupts prescription. The clock resets from the date of service.

B) Acknowledgement of liability by the debtor. This can be express (written) or tacit (implied by conduct, such as making a part payment). This is why your credit team should always be gathering written acknowledgements from debtors in arrears.

Our team’s experience: We have seen deals worth hundreds of thousands of rands saved simply because a credit manager had the foresight to get a signed Acknowledgement of Debt (AOD) before prescription ran out. If you don’t know what an AOD is or how to use one, read this: What Is an Acknowledgement of Debt (AOD) and Why Does It Really Matter?

What counts as a tacit acknowledgement?

A part payment
A written payment arrangement
A debtor’s email acknowledging they “still owe” the amount
A signed statement of account

What does NOT interrupt prescription:

Sending a letter of demand alone (without serving legal process)
Internal credit notes or journal entries
Verbal promises to pay (undocumented)
Informal WhatsApp messages without a clear admission of liability

5. What Delays (Pauses) Prescription?

Certain circumstances delay prescription — meaning the clock is temporarily paused, not reset.

Under Section 13 of the Prescription Act, prescription is delayed when:

The debtor is a minor or under curatorship
The creditor and debtor are married to each other
The creditor is prevented by superior force (vis major) from interrupting prescription
The debtor is outside the Republic and the debt is not connected to any property in South Africa
The parties are in an arbitration process

For most B2B situations, the most practically relevant delay is the vis major provision — which has been argued in the context of events like major disruptions that make legal proceedings temporarily impossible.

6. Prescription and the National Credit Act: What’s Changed?

If you deal with consumer debt governed by the National Credit Act (NCA), there is an additional layer of protection for debtors introduced by Section 126B of the NCA.

Under Section 126B:

No person may sell a debt that has been extinguished by prescription.
No person may continue to collect or reactivate a prescribed debt under an NCA credit agreement — even if the consumer would have raised prescription as a defence had they known about it.

This provision is a significant strengthening of the debtor’s position in consumer credit contexts. It means that even if a debtor doesn’t formally raise prescription, a collector cannot pursue an NCA-governed prescribed debt if it is reasonable to assume the debtor would have raised it.

For B2B creditors, the NCA does not typically apply — but this rule is a useful reminder that prescribed debts, once extinguished, should not be pursued. Doing so exposes your business to regulatory risk and reputational damage.

7. B2B vs Consumer Debt: Does Prescription Work Differently?

This is one of the most common questions we receive at Kredcor. The answer is: the core prescription periods under the Prescription Act are the same. However, the process and protections differ significantly:

Factor	B2B (Commercial) Debt	Consumer Debt (NCA)
Governing Act	Prescription Act 68 of 1969	Prescription Act + NCA Section 126B
Prescription Period (ordinary)	3 years	3 years
Can prescribed debt be sold?	Generally yes, but inadvisable	Explicitly prohibited (NCA s126B)
Can prescribed debt be collected?	Debtor must raise the defence	Collector cannot pursue, even proactively
Regulated collector required?	Yes (Debt Collectors Act)	Yes (Debt Collectors Act + NCA)

8. Five Troubleshooting Tips: What to Do When You Suspect a Debt May Have Prescribed

Troubleshooting Tip 1: Calculate the Exact Start Date — Don’t Guess

Pull the original invoice, the credit agreement, and the payment terms. Establish the precise date the debt became due. Do not use the invoice date if payment terms apply. If there is any ambiguity around acceleration clauses or conditional payment, get a legal or expert opinion before writing the debt off.

Troubleshooting Tip 2: Search for Any Interruption Events

Go through your full correspondence file. Look for:

Any signed acknowledgement of debt, payment arrangement, or statement of account signed by the debtor
Any summons or legal process previously served
Any part payment made, however small

Even a single part payment can reset your prescription clock entirely. I tested this approach on an account handed to us that was nearly four years old — and we found a partial EFT payment made 26 months prior that had been overlooked. The debt had not prescribed. We recovered it in full.

Troubleshooting Tip 3: Do Not Demand Payment on a Clearly Prescribed Debt

If you have determined that prescription has run and no interruption occurred, stop collection action immediately. Pursuing a prescribed B2B debt exposes you to a complaint to the Council for Debt Collectors. For NCA-governed debt, it is a direct statutory violation.

Troubleshooting Tip 4: Implement a Prescription Diary in Your Debtors’ System

Every overdue account should have a “prescription warning date” flagged — typically 60 days before the three-year mark. Your credit team should be alerted well in advance so that they can take action (obtain an AOD, serve summons, or hand over to a collection agency) before the clock runs out. This is standard practice in any professional credit department.

Troubleshooting Tip 5: When in Doubt, Hand Over Early

The single most effective way to avoid losing a debt to prescription is to hand it over to a professional recovery agent early — ideally before the 90-day mark. Our team at Kredcor found, through analysis of our own case data, that accounts handed over before 90 days have a recovery rate of 80–90%. After 240+ days, that rate drops dramatically — and prescription risk rises sharply. Don’t wait until it’s too late.

9. Real-World Scenarios: How Prescription Catches Businesses Off Guard

Scenario 1: The forgotten invoice A Johannesburg-based manufacturer delivered goods in January 2023. Payment terms were 30 days. The debtor made excuses for six months, then went silent. The credit manager assumed the legal team had it in hand. By February 2026, the three-year clock had run — and no summons had been served and no AOD obtained. The R180,000 debt was prescribed.

Scenario 2: The WhatsApp promise A Cape Town SME owner had WhatsApp messages from a debtor promising to pay “next week” repeatedly over two years. Not one of those messages contained a clear acknowledgement of the specific amount owed. The court held that the messages were not a tacit acknowledgement sufficient to interrupt prescription. The debt was lost.

Scenario 3: The part payment that saved the day A Durban logistics company handed an overdue account to Kredcor with 45 days to spare before prescription. We discovered the debtor had paid R500 against a R90,000 balance two years prior — resetting the prescription clock. We recovered the full balance. The key was acting fast and conducting a thorough review.

These scenarios are not hypothetical; they reflect patterns we see regularly across industries. Prescription of debt in South Africa is a very real operational risk for any credit-granting business.

11. Frequently Asked Questions

Q1: What is the prescription period for debt in South Africa in 2026?

A: For most ordinary commercial debts — such as unpaid invoices for goods or services — the prescription period is three years under the Prescription Act 68 of 1969. Mortgage bonds and judgment debts prescribe after 30 years. Bills of exchange and notarial contracts prescribe after six years. As of 2026, these periods remain unchanged.

Q2: Can a debtor refuse to pay a prescribed debt in South Africa?

A: Yes. Once a debt has been extinguished by prescription, the debtor can raise prescription as a complete defence in any legal proceedings. The court will then dismiss the claim. However, the debtor must actively raise this defence — a court will not automatically apply prescription on the debtor’s behalf in civil proceedings. It is the debtor’s right to invoke it or waive it. Importantly, if a debtor voluntarily pays a prescribed debt, that payment is treated as valid and cannot be reclaimed.

Q3: Does sending a letter of demand stop prescription in South Africa?

A: No. A letter of demand, on its own, does not interrupt prescription. Prescription is interrupted only by (a) the service of valid legal process (such as a summons) on the debtor, or (b) a written or tacit acknowledgement of liability by the debtor. Many creditors mistakenly believe that a demand letter resets the clock — it does not. This is one of the most costly misconceptions in credit management.

Q4: What happens to prescription if the debtor makes a part payment?

A: A part payment is generally treated as a tacit acknowledgement of liability, which interrupts prescription and resets the three-year clock from the date of that payment. This is why credit teams should always record and date any payments received against overdue accounts — even small ones. Similarly, a signed payment arrangement or acknowledgement of debt (AOD) will interrupt prescription. The moment any new acknowledgement is obtained, document it meticulously and date it.
