Understanding Medical Negligence Time Limits in South African Law

Medical negligence claims in South Africa are subject to the Prescription Act 68 of 1969, with section 12(3) giving a claimant a three-year window from the date they knew or ought reasonably to have known both the identity of the potential wrongdoer and the facts giving rise to the claim. In NVM obo VKM v Tembisa Hospital (CCT202/20, 2022) the Constitutional Court confirmed that the date-of-knowledge test, not the date of the negligent act itself, starts the limitation period running. Issuing summons in time interrupts prescription; failing to do so before the three-year deadline runs out generally bars the claim, subject to narrow exceptions such as section 38 of the Act (which a court may invoke where it would be grossly unreasonable to let prescription run). The same three-year framework applies whether the matter is filed in the Magistrate’s Court (for claims up to R200,000) or the High Court (above that quantum).

The Statutory Framework: The Prescription Act 68 of 1969

South African medical negligence claims are governed by the general prescription regime in the Prescription Act 68 of 1969, not by a sector-specific medical malpractice limitation statute. Section 12(3) sets the basic three-year period for any “debt” not otherwise provided for — the category into which a medical negligence claim falls once the cause of action has crystallised.

A claim “prescribes” (becomes legally unenforceable) once the three-year period has expired without summons being issued, unless interrupted or suspended under the Act. Section 17 of the Act confirms the effect of prescription: once a debt prescribes, the creditor loses the right to enforce it. There is no separate “medical malpractice” limitation regime that overrides these rules — practitioner, hospital, and state-defendant claims all run through the same statutory filter.

The Date-of-Knowledge Test: When the Three Years Start

Section 12(3) starts the period from the date the debt arises — but for medical negligence the Constitutional Court confirmed in NVM obo VKM v Tembisa Hospital (CCT202/20) [2022] ZACC 11 that the debt is deemed to arise only when the claimant actually or constructively knows both:

• the identity of the potential wrongdoer, and
• the facts from which the claim arises (the causal link between treatment received and harm suffered).

“Ought reasonably to have known” is judged objectively — the claimant must take reasonable steps to identify the responsible practitioner or institution and to investigate the connection between the treatment and the harm. Knowledge of the harm alone is not enough; knowledge of the causal link and of who to sue is the trigger. The benchmark is what a reasonable claimant in the same position would have come to know, exercising ordinary diligence.

Distinctions and Common Misconceptions

The single most common error lay claimants make is to confuse the date of the negligent act with the date of knowledge. The key distinctions are worth stating plainly:

• The three-year rule runs from the date of knowledge, not from the date of the incident.
• A claim does not prescribe just because three years have passed since the negligent act; it prescribes three years after the claimant knew, or ought reasonably to have known, the relevant facts and identity.
• The Prescription Act does not allow a fresh three-year period to restart simply because the claimant was “still suffering” — the period is fixed by the knowledge test, not by ongoing harm.
• Where the claimant deliberately avoids investigation (for example, on legal advice not to investigate), the court can still treat the date of knowledge as having arrived at an earlier reasonable point.

Burger Huyser Attorneys’ general litigation practice is built around exactly this kind of date-sensitive motion work — disputes where the timing of a plaintiff’s investigation drives whether the matter proceeds or is shut out at the door.

Interruption and Suspension of Prescription

Once the three-year window is running, certain steps can stop or reset the clock. The most important are summarised in the table below.

Mechanism	Source in the Prescription Act	Effect
Issuance of summons	Section 15(1)	Once summons is issued and properly served on the defendant (or via the sheriff), prescription is interrupted and a fresh period begins to run.
Acknowledgement of debt	Section 14	A written, signed acknowledgement by the defendant (or an authorised agent) resets prescription.
Part-payment of the debt	Section 14	Part-payment by the defendant interrupts prescription on the same basis as an acknowledgement.
Minority / legal disability	Section 6	Prescription does not run against a minor or any person under legal disability until they reach majority or the disability ends.
Court’s discretion to override prescription	Section 38	The court may decline to give effect to prescription where it would be “grossly unreasonable” to do so, having regard to the nature of the debt and any prejudice to the claimant. Narrow safety valve; not a routine remedy.

The practical takeaway is that a claimant who is aware (or ought reasonably to be aware) of the injury, of who caused it, and of the causal connection should act decisively. A medical negligence matter that is investigated and summonsed within three years of that knowledge point is, on the prescription question alone, on solid ground.

Practical Filing Layers: Where to Sue and Why It Matters

The prescription rules are national; the filing venue depends on quantum and geography. Three practical layers matter at the moment a claim is ready to be issued.

Filing decision	Rule	Practical consequence
Quantum determines court	Claims up to R200,000 file in the Magistrate’s Court (district of the defendant’s residence or where the cause of action arose); claims above that quantum go to the High Court.	The same three-year prescription window applies in either forum. The court you choose affects procedural complexity and costs, not the limitation period.
Gauteng seat selection	Matters above R200,000 file in the Gauteng Division of the High Court. The matter is filed at the seat having jurisdiction over the defendant or the place where the negligent treatment occurred (Johannesburg seat or Pretoria seat).	A claim arising from treatment at a Pretoria- or Centurion-based private practice generally files at the Pretoria seat; a claim arising from a Johannesburg or East Rand facility generally files at the Johannesburg seat.
Notice to a state defendant	Where a public hospital or state institution is the defendant, special statutory notice provisions under the State Liability Act 20 of 1957 apply and must be observed before summons is issued.	Failing to lodge the section-by-section notice in time can defeat a state-defendant claim independently of the prescription clock — a separate pitfall in addition to the limitation period.

Pre-litigation mechanics

Most medical negligence claims are preceded by a letter of demand to the healthcare provider or institution, often coupled with a request for the clinical file under section 23 of the National Health Act 61 of 2003, before summons is drafted. A claimant’s request for the clinical file is itself a useful piece of evidence on the date-of-knowledge question, because it records the moment at which the claimant took positive steps to investigate the suspected injury.

The Standard Medical Negligence Claim, Briefly

The substantive test for medical negligence is unchanged from the prescription rules: a healthcare provider must exercise the degree of skill and care that a reasonably competent practitioner in that field would exercise. The most common heads of claim are misdiagnosis, surgical error, birth injury, medication error, failure to obtain informed consent, and inadequate post-operative care.

Quantum in a successful claim covers past and future medical expenses, loss of earnings (past and future), general damages for pain and suffering and loss of amenities of life, and (in fatal cases) a claim under the Loss of Support Act 23 of 1966 by dependants of the deceased.

Why engage a specialist for the prescription side

The prescription question in a medical negligence claim is rarely a standalone issue — it intersects with the date-of-knowledge inquiry, causation, the form of summons, and the rule on state-defendant notice. A practitioner who routinely runs High Court motion work (including applications to lift prescription under section 38 where appropriate) is the appropriate profile for this work. Burger Huyser Attorneys runs medical negligence claims through its general litigation practice, with intake handled at the nearest branch — the same bench that handles commercial and family-related High Court motion work under Directors such as Nadine Roesch-Prinsloo (Roodepoort, head of general litigation) and Herman Bonnet (Pretoria).

Frequently Asked Questions

How long do I have to sue for medical negligence in South Africa?

Three years from the date you knew or ought reasonably to have known the identity of the wrongdoer and the facts giving rise to the claim — under section 12(3) of the Prescription Act 68 of 1969, as confirmed by the Constitutional Court in NVM obo VKM v Tembisa Hospital (CCT202/20, 2022).

Is the three-year period counted from the date of the negligent treatment?

No — it runs from the date the claimant actually or constructively knows both the identity of the potential wrongdoer and the relevant facts. Where the injury is only discovered later (for example, a delayed cancer diagnosis or an instrument left behind after surgery), the period starts from when that knowledge was reasonably obtainable, not from the date of the negligent act itself.

Can I still sue if the negligent act happened more than three years ago but I only just found out about the injury?

Possibly, yes — the date-of-knowledge test means the three years runs from when you knew or ought reasonably to have known, not from when the negligent act occurred. The sooner you consult an attorney, the better; delay in investigating can itself be treated as constructive knowledge and shorten the available window.

What happens if I issue summons in time but the defendant raises prescription?

Issuing summons in time interrupts prescription under section 15(1) of the Act, after which a fresh prescription period runs. The court will examine whether the summons was properly issued and served within the three-year window from the date of knowledge.

Can a child sue for medical negligence after turning 18?

Yes — section 6 of the Prescription Act suspends prescription against a minor (and against any person under legal disability) until they reach majority or the disability ends. The three-year period therefore begins running from age 18 in most cases.

What if my claim prescribes and I didn’t know?

Section 38 of the Prescription Act allows a court, in narrow circumstances, to refuse to give effect to prescription where doing so would be “grossly unreasonable” given the nature of the debt and the prejudice to the claimant. This is an exception, not a routine remedy, and a court will weigh it against any prejudice to the defendant.
