Prescription of Debt in South Africa: the 3-Year Rule (2026)

Debt in South Africa does not last forever. The Prescription Act sets a clock on most kinds of debt, and once that clock runs out, the debt becomes legally uncollectable even though it was never actually paid.

Information last verified on 23 July 2026. This page provides general legal information about South African law on the prescription of debt, not legal advice on your individual situation.

The four prescription periods (s11)

Section 11 of the Prescription Act sets four periods:

• 30 years: any debt secured by a mortgage bond, any judgment debt, any debt for tax imposed under any law, and any debt owed to the State for a share of profits or royalties from mining.
• 15 years: a debt owed to the State arising from a loan, or a sale or lease of land, by the State to the debtor, unless a longer period would otherwise apply.
• 6 years: a debt arising from a bill of exchange or other negotiable instrument, or from a notarial contract, unless a longer period would otherwise apply.
• 3 years: "save where an Act of Parliament provides otherwise", every other debt.

That residual 3-year period is the one that matters for most everyday consumer debt: personal loans, credit card balances, retail accounts, and most contractual debts not otherwise listed.

When the clock starts running (s12)

Prescription generally starts running as soon as a debt is due (s12(1)). There is an important qualification for debts a creditor might otherwise claim it did not know about: a debt is not treated as due until the creditor knows the debtor's identity and the facts giving rise to the debt, but a creditor is deemed to have that knowledge if it could have found it out by exercising reasonable care (s12(3)). In practice, this stops a creditor from arguing the clock only started once it actually noticed the debt, if reasonable diligence would have revealed it sooner.

What interrupts prescription (ss14 to 15)

Two things reset or pause the clock. An express or tacit acknowledgement of liability by the debtor interrupts prescription, and once that happens, prescription "shall commence to run afresh" from the date of the acknowledgement (s14). Separately, being served with legal process (which the Act defines broadly, covering a petition, a notice of motion, a pleading, and any document by which legal proceedings are commenced) that claims payment of the debt also interrupts prescription (s15(1)). That interruption lapses, though, if the creditor does not successfully pursue the claim to final judgment, or abandons the judgment, or has it set aside (s15(2)). Where the creditor does obtain a final judgment, prescription starts running afresh from the date the judgment becomes executable (s15(4)), at which point the debt becomes a judgment debt with its own 30-year prescription period under s11(a).

Prescribed credit debt: the National Credit Act adds a stronger rule

The Prescription Act is general law and applies to debt of every kind. For credit agreements specifically (loans, credit cards, store accounts and similar arrangements regulated by the National Credit Act), section 126B adds a further, stronger protection once the debt has prescribed. It provides that no person may sell a credit agreement debt that has been extinguished by prescription, and no person may "continue the collection of, or reactivate" such a debt where the consumer raises, or would reasonably have raised, the defence of prescription. This is a credit-agreement-specific bar, separate from and stronger than the general common-law position described below, and it is the one most relevant to the credit debts most readers will be asking about.

Does paying revive a prescribed debt? Two separate rules, not one

This is a common source of confusion, and the two legal positions need to be kept apart rather than collapsed into a single rule. At common law, section 10(3) of the Prescription Act provides that "payment by the debtor of a debt after it has been extinguished by prescription... shall be regarded as payment of a debt." That means if you voluntarily pay a prescribed debt, the payment is valid and you cannot later claim it back as paid in error, but this rule does not, on its own, reopen the balance to fresh collection by the creditor. For credit agreement debts specifically, section 126B of the National Credit Act goes further: once the debt has prescribed and you raise, or would reasonably raise, prescription as a defence, the credit provider is barred from continuing to collect it, full stop, regardless of any partial payment you may have already made. Do not treat "making a payment revives the whole debt" as a blanket rule; for the credit debts most readers are asking about, it is not correct.

There is one further point worth flagging honestly: some online commentary states that section 126B commenced on a specific date in 2015 and that its collection bar does not apply retrospectively to debts that had already prescribed before then. That specific commencement date and retrospectivity claim could not be independently verified against a primary Gazette or court record for this page, so treat it as unconfirmed, and get current advice if the exact timing affects an old debt of yours.

What to do if a collector is chasing an old debt

Work out what type of debt it is (a credit agreement or something else), when it actually fell due, and whether anything has happened since, such as an acknowledgement or a court process, that would have interrupted the clock. Prescription is a defence you can raise, not something you have to ignore, argue about informally, or pay to make go away. If you are unsure where you stand, an attorney, or Legal Aid South Africa if you cannot afford one, can help you work through the specific dates.
