Prescription Periods in SA Law: What Every Attorney Must Track

Prescription is the legal mechanism by which a debt is extinguished after the passage of a defined period. For South African attorneys, prescription is not an abstract legal concept — it is a daily operational risk. Miss a prescription deadline on a client's claim, and you face a malpractice suit that can cost millions, end your career, and destroy your firm's reputation. Track prescription properly, and you sleep at night knowing no client matter is silently expiring.

This guide covers the Prescription Act 68 of 1969, the standard and exceptional prescription periods that apply in SA legal practice, and how to build a prescription tracking system that actually works (spoiler: spreadsheets do not work).

The Prescription Act 68 of 1969 — the basics

The Prescription Act 68 of 1969 governs the extinction of debts by prescription in South Africa. The key sections for attorneys:

Section 11: Standard prescription periods

Section 11 sets out the standard periods: (a) 30 years for any debt secured by a mortgage bond, judgment debt, or tax debt; (b) 15 years for any debt owed to the State; (c) 6 years for any debt arising from a negotiable instrument or bill of exchange; (d) 3 years for any other debt (which covers most civil claims — delictual, contractual, restitutionary).

For most SA attorneys, the 3-year prescription period under Section 11(d) is the critical one. RAF claims, personal injury, motor vehicle accidents, breach of contract, professional negligence — all are subject to the 3-year rule, with the clock starting on the date the debt became due (typically the date of the incident or breach).

Section 12: When prescription begins to run

Section 12 provides that prescription begins to run as soon as the debt is "due" — meaning the creditor has knowledge of the identity of the debtor and of the facts from which the debt arises. Importantly, prescription does not begin to run until the creditor is aware (or could reasonably be aware) of all the facts giving rise to the claim. This is the "completion of the cause of action" principle.

For RAF claims, prescription runs from the date of the accident. For medical negligence, it runs from the date the negligence occurred (or was discovered — see Section 12(3) below). For breach of contract, it runs from the date of breach. For professional negligence against an attorney, it runs from the date the negligent act was committed (or, in some cases, discovered).

Section 13: Interruption of prescription

Prescription can be interrupted by: (a) acknowledgment of liability by the debtor (in writing or by part-payment); or (b) service of a summons or other process on the debtor. When prescription is interrupted, the clock resets — a fresh 3-year period begins from the date of interruption.

This is critical for attorneys: service of a summons interrupts prescription. But service must be effective — a summons issued but not served within 12 months may not interrupt prescription (the rules are technical and case-law dependent). Do not assume issuance alone is enough.

Section 14: Completion of prescription

Prescription is completed (the debt is extinguished) at the end of the last day of the prescription period. If the last day is a weekend or public holiday, prescription completes on the next business day. There is no automatic extension.

Exceptions to the 3-year rule

Several exceptions modify the standard 3-year prescription period. Attorneys must know these by heart:

Section 12(3): Delayed discovery

If the creditor could not reasonably have known about the debt (e.g., a latent defect in a property that only manifests years later, or professional negligence that only comes to light on audit), prescription does not begin to run until the creditor has knowledge (or reasonably should have knowledge) of the cause of action. This is the "discovery rule" — it extends prescription in cases of concealed or latent harm.

Section 13(1)(a): Acknowledgment of liability

If the debtor acknowledges the debt in writing or makes a part-payment, prescription is interrupted and a fresh 3-year period begins. This is why every collection matter should include a strategy of obtaining written acknowledgment before prescription lapses.

Section 13(1)(b): Service of process

Service of a summons, application, or arbitration demand interrupts prescription. But the process must be served — issuance alone is not enough. If service is delayed (e.g., the sheriff cannot locate the debtor), prescription may complete before service is effected.

Section 15: Minors and persons under disability

Prescription does not run against a minor, a person of unsound mind, or a person under curatorship. The prescription period only begins when the disability ends (e.g., the minor turns 18). For RAF claims involving minors, this can extend the prescription period by many years.

Section 16: Extended prescription for minors

For claims by minors, prescription does not complete before the minor's 21st birthday — even if the standard 3-year period would otherwise have lapsed. So a 5-year-old injured in a motor vehicle accident in 2024 has until 2040 (their 21st birthday) to institute action, not 2027.

The 7 prescription traps that catch SA attorneys

Based on published Legal Practitioners' Indemnity Insurance claims and LPC disciplinary matters, the 7 most common prescription traps are:

1. 1RAF claims where the accident date is uncertain (hit-and-run, single-vehicle accidents) — the prescription clock starts from the accident, but the firm may record it incorrectly from the date of instruction.
2. 2Medical negligence where the negligence was not immediately apparent — firms sometimes count prescription from the surgery date rather than the discovery date.
3. 3Section 12(3) delayed discovery cases — firms fail to plead the discovery rule and lose claims that should have been valid.
4. 4Service of summons delays — firm issues summons to interrupt prescription, but the sheriff takes 4 months to serve, and prescription completes in the interim.
5. 5Minor clients — firms fail to flag that prescription is suspended, then discover the suspension 5 years later when the client turns 18 and asks about the claim.
6. 6Acknowledgment of liability strategy missed — firms proceed straight to summons when a written acknowledgment would have been faster and cheaper.
7. 7Multiple defendants with different prescription dates — the firm treats all defendants as having the same prescription date, when in fact one defendant's prescription lapsed 6 months before the others.

How to build a prescription tracking system that works

The minimum requirements for a prescription tracking system:

• •Every matter with a prescription component must have the prescription date calculated and stored in the system — not in an attorney's head or a calendar reminder.
• •Prescription dates must be calculated automatically based on the cause of action, the incident date, and any exceptions (minority, disability, delayed discovery).
• •Alerts must fire at 12 months, 6 months, 3 months, and 1 month before prescription lapses — escalating to senior partner level as the deadline approaches.
• •A weekly "prescription report" must list every matter with prescription expiring in the next 12 months, with the responsible attorney named.
• •Service of summons must automatically update the prescription date (resetting it) — not require manual entry.
• •Minority and disability suspensions must be flagged on the matter, with the prescription clock set to resume on the relevant date.

The cost of a missed prescription

When a firm misses a prescription deadline, the consequences cascade:

1. 1The client's claim is extinguished — they lose the right to recover.
2. 2The client sues the firm for professional negligence — the damages are the value of the lost claim.
3. 3The firm's professional indemnity insurer pays out, but premiums rise significantly (often 50–100% for 3 years).
4. 4The matter must be reported to the Legal Practice Council, triggering a disciplinary investigation.
5. 5The firm's reputation suffers, especially in tight legal markets like conveyancing or RAF.
6. 6The responsible attorney may face personal disciplinary action, including suspension.

For a single missed RAF prescription on a R2 million claim, the firm's total cost (insurance excess, premium increase, lost client, reputational damage) typically exceeds R500,000. For a missed conveyancing prescription that delays a property transfer, the cost is lower but the reputational damage in the local conveyancing community is severe.

What to look for in prescription tracking software

When evaluating legal practice management software, ask vendors:

• •Does the software automatically calculate prescription dates based on cause of action and incident date?
• •Does it handle minority and disability suspensions?
• •Does it send escalating alerts as prescription approaches (12 months, 6 months, 3 months, 1 month)?
• •Does it auto-reset prescription when a summons is served?
• •Can it generate a weekly prescription report grouped by attorney?
• •Does it flag matters where prescription is uncertain (e.g., delayed discovery cases) for senior review?

If the vendor cannot answer yes to all six, the software is not adequate for prescription tracking. Generic legal software (Clio, PracticePanther) typically fails on the SA-specific calculations — they do not understand Section 15 minority suspensions or Section 13(1)(b) service-of-sumns interruptions under SA law.

A prescription tracking discipline that actually works

Beyond software, every firm needs a prescription discipline. The minimum practices:

1. 1Every new matter: calculate prescription at intake. No exceptions. The intake form must require the attorney to identify the cause of action, the incident date, and any exceptions.
2. 2Weekly: every attorney reviews the prescription report for their matters. The review is logged — not just "I checked" but "I checked and here are the matters needing action this week."
3. 3Monthly: a partner (not the responsible attorney) audits prescription tracking across the firm. Independent review catches the cases where the responsible attorney has gone stale.
4. 4Quarterly: a partner reviews every matter with prescription expiring in the next 6 months. Decision: serve summons now, or risk it? Most prescription losses happen when firms "wait for settlement" too long.
5. 5On service of summons: confirm effective service within 12 months. If service is delayed, prescription is at risk — escalate immediately.

Software makes this discipline possible. Without software, the discipline collapses under volume — a 200-matter firm cannot manually track prescription across 200 files week after week. But software alone is not enough — the discipline must be enforced from partner level down. One weak link (one attorney who does not check the weekly report) and prescription risk reappears.
