Do Medical Negligence Claims Prescribe? | Understanding Timelines

Yes, medical negligence claims in South Africa prescribe — generally after three years from the date of knowledge, under the Prescription Act 68 of 1969. The clock does not run from the date of the negligent treatment itself; it runs from the date the patient reasonably ought to have known that the harm was caused by medical negligence. Issuing and serving a summons on the health-care provider (or their professional indemnity insurer) before the three-year period ends is the standard mechanism that interrupts prescription.

The Short Answer: Yes, They Prescribe

Medical negligence claims are civil wrongs (delicts) and are subject to prescription under the Prescription Act 68 of 1969. The general rule is three years from the date of knowledge — not from the date the negligent treatment happened. If harm was only recently discovered, the three-year clock may have started only recently, but this is a fact-specific determination that requires a legal assessment rather than a guess.

Prescription is not a soft target. Once a claim has run, the court will generally dismiss it if the defendant raises the defence — and there is no routine procedure for reviving an out-of-time medical negligence claim.

What “Date of Knowledge” Actually Means

The “date of knowledge” is the trigger point from which the three-year period is calculated. It is not a single date plucked from the patient’s memory of when they first felt angry, sad, or suspicious. It is a legal construct, judged objectively against what a reasonable patient in the same position would have known or ought to have known. To start the clock, the patient must have known or reasonably ought to have known:

• The identity of the health-care provider — the doctor, surgeon, anaesthetist, hospital, clinic, or nursing institution that is alleged to have been negligent.
• The facts giving rise to the claim — that harm was suffered, and that the harm was caused by the medical conduct in question.
• That the conduct was potentially wrongful — the claimant does not need to know the full legal basis for the claim, only that they have suffered harm caused by medical treatment.

This is a fact-specific inquiry, and the date of knowledge is not always the date of the operation, the date the patient was discharged, or the date the patient was first told something went wrong. A late diagnosis, a complication that only manifested years later, or harm that was initially attributed to natural progression can all shift the date of knowledge earlier than the patient might assume.

How the Prescription Period Is Counted

The three-year period is calculated from the date of knowledge, not from the date of the negligent act. For an adult claimant who knew or ought reasonably to have known on, say, 1 March 2024, prescription would complete on 1 March 2027. “Completes” means that is the last day on which a summons can validly be issued and served to interrupt prescription — after that date, the claim is extinguished unless a narrow extension applies.

The Prescription Act Framework (Section by Section)

The Prescription Act 68 of 1969 is the statutory framework that governs prescription of civil claims in South Africa, including medical negligence delicts. The sections that matter most for a medical negligence claim are:

Section	Effect	Practical impact for medical negligence claims
Section 3	Three-year prescription for civil debts once the debt arises	Default rule for medical negligence claims
Section 6	30-year “long” period for debts not governed by an earlier Act	Rarely relevant; the three-year period almost always applies to medical negligence delicts
Section 12	Sets out when prescription commences to run (a debt is “due” when the creditor knows, or ought reasonably to know, the identity of the debtor and the facts from which the debt arose)	The statutory home of the date-of-knowledge test
Section 13(1)(a)	Prescription does not run against a minor	A minor’s medical negligence clock starts only when they turn 18 — they then have three years
Section 13(1)(b)	Prescription does not run against a person under curatorship	Clock suspended while curatorship is in place
Section 14	Acknowledgement of debt by the debtor	A written acknowledgement of debt, or any payment on account, by the health-care provider or their duly authorised representative interrupts prescription
Section 15(1)	Service of process on the debtor interrupts prescription	Issuing and serving a summons on the health-care provider (or their insurer) is the standard interruption mechanism

Protections for Minors and Persons Under Legal Disability

Section 13 of the Prescription Act carves out limited protections for claimants who are not in a position to act on their own behalf:

• Minors: A child who suffered negligent medical treatment as an infant does not start running a three-year clock until they reach majority (18 years). They then have the full three years from their 18th birthday to issue and serve summons. This is not a lifetime extension — it is a deferred start.
• Persons under curatorship: Prescription does not run while the curatorship subsists. Once the curatorship is terminated, the clock may begin to run (subject to legal advice on the specific circumstances).
• Mental illness or cognitive impairment on its own does not automatically suspend prescription — only formal curatorship does. This is one of the more commonly misunderstood traps in medical negligence work, and it is one of the reasons an early legal assessment matters.

What Interrupts Prescription (and What Does Not)

Knowing what counts as an interruption is as important as knowing the date of knowledge. The Prescription Act recognises a narrow set of interruption mechanisms:

• Issuing and serving a summons on the health-care provider (or their professional indemnity insurer) — the standard and most reliable interruption mechanism under section 15(1).
• A written acknowledgement of debt signed by the health-care provider or their duly authorised representative under section 14.
• Payment made on account of the claim, even partial, by or on behalf of the provider under section 14.

What does not interrupt prescription for a civil medical negligence claim:

• Filing an HPCSA complaint — the Health Professions Council of South Africa process is a regulatory complaint mechanism, separate from the civil claim. The time-bar for the civil claim keeps running unless one of the section 14 or 15 mechanisms above is also triggered.
• A demand letter without summons — does not by itself interrupt prescription under the Act, although it may be practically useful in prompting an acknowledgement of debt.

What Happens If Prescription Completes

A claim that has prescribed is not extinguished automatically — the defendant must raise prescription as a defence in the pleadings. Once raised, prescription is generally a complete defence and the claim will be dismissed unless one of the narrow exceptions applies. Section 17 of the Act gives the court a discretion in limited circumstances (so-called “anticipatory prescription”), but this discretion is exercised sparingly and is not something a claimant can rely on prospectively.

Common Prescription Traps in Medical Negligence Cases

Several recurring patterns catch claimants out:

• “I only just found out” — the date of knowledge is judged objectively, not by when the patient felt ready to act. If a reasonable patient would have known on an earlier date, that earlier date is what counts.
• Late diagnosis — where negligent treatment caused an injury that was only diagnosed years later, the clock runs from when the negligent cause was reasonably knowable, which is often earlier than the patient assumes.
• Birth injury claims — for obstetric or neonatal injuries, the date of knowledge can be set quite early (for example, when the injury was first identified at birth or during follow-up care). The section 13(1)(a) deferral for minors is the operative protection, not the date of knowledge itself.
• Treatment that spanned multiple providers — the date of knowledge may need to be assessed separately for each provider, depending on when each one’s negligence became reasonably knowable.

Practical Steps If You Suspect Prescription Is Close

1. Get the medical records in writing as soon as possible — they anchor the date-of-knowledge analysis.
2. Identify every health-care provider who was involved in the treatment (surgeon, anaesthetist, nursing staff, institution).
3. Approach an attorney for a date-of-knowledge assessment — this is a fact-specific legal opinion that should not be guessed at.
4. If the claim is still within the three-year period, the standard interruption (summons) is the safe route; if it is borderline, urgent legal advice is needed before any further steps are taken.
5. Do not rely on the HPCSA complaint process alone to preserve a civil claim.

Burger Huyser Attorneys’ general litigation practice, run by Director Nadine Roesch-Prinsloo at the Roodepoort branch, handles personal-injury and professional-negligence claims across Gauteng — prescription assessments are precisely the kind of urgent intake the firm can assist with, even where medical negligence sits outside any dedicated department.

Where These Claims Are Filed

The Prescription Act applies uniformly across South Africa, so the substantive three-year rule does not vary by province. Where a claim is filed does still depend on quantum:

Quantum	Forum	Seat (illustrative)
Up to R200 000	Magistrate’s Court	The district where the negligent treatment occurred, or where the patient resides
Above R200 000	Relevant High Court Division	Gauteng Division (Johannesburg or Pretoria seat), KwaZulu-Natal Division (Pietermaritzburg or Durban seat), Western Cape Division (Cape Town), and so on

Issuing and serving summons in the correct forum is what actually interrupts prescription under section 15(1), so a misfiled summons can be as fatal to a claim as a late one. The Health Professions Council of South Africa regulates practitioners but is not a court — an HPCSA complaint does not interrupt civil prescription, and confusing the two processes is one of the more common ways claimants lose their rights without realising it.

When a Claim Is Already Out of Time

• A prescription defence is not automatically raised — it must be pleaded.
• Section 17 of the Act gives courts a discretion in limited circumstances; the bar is high and the discretion is exercised sparingly.
• There is no realistic route to revive a clearly out-of-time medical negligence claim, which is why the conservative step is to act early rather than late.

Frequently Asked Questions

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

Three years from the date of knowledge under the Prescription Act 68 of 1969 — meaning the date the patient knew or reasonably ought to have known the identity of the health-care provider and the facts giving rise to the claim. For minors, the three-year clock only starts when they turn 18 (section 13(1)(a)), and for persons under curatorship it is suspended while the curatorship subsists (section 13(1)(b)). The clock runs from date of knowledge, not from the date the negligent treatment happened.

Does filing an HPCSA complaint stop prescription on my civil medical negligence claim?

No. The Health Professions Council of South Africa complaint process is a regulatory process, separate from a civil claim. An HPCSA complaint does not interrupt prescription for the civil claim under the Prescription Act — issuing and serving a summons on the health-care provider (or their insurer) is the standard mechanism that interrupts prescription under section 15(1).

What is the “date of knowledge” in a medical negligence claim?

The date on which the claimant (or a reasonable patient in their position) knew or ought to have known (a) that they had suffered harm, (b) that the harm was caused by medical negligence, and (c) the identity of the health-care provider responsible. It is judged objectively — what a reasonable patient would have known — and is often earlier than the patient personally feels ready to act. It is fact-specific and should be assessed by an attorney before any assumption is made about how much time is left.

Can a medical negligence claim be revived after the 3-year period?

Generally no. Prescription under the Prescription Act 68 of 1969 is a complete defence once it has run, and section 17 gives courts only a narrow discretion to relieve against it in limited circumstances — a discretion that is exercised sparingly. There is no routine procedure for reviving an out-of-time medical negligence claim, which is why urgent legal advice is needed the moment the issue is identified, not after the period has run.

Is there a separate time limit for minors in medical negligence claims?

Yes — under section 13(1)(a) of the Prescription Act, prescription does not run against a minor. The three-year clock starts only when the minor turns 18, giving them until their 21st birthday to issue and serve summons. This is not a lifetime extension; it is a deferred start. For minors, the operative date-of-knowledge analysis is still important if a claim is brought on their behalf during minority.

If you are concerned that a medical negligence claim may be close to prescription — or you have only just discovered an injury that may have been caused by negligent treatment — the most useful first step is a date-of-knowledge assessment by an attorney. Burger Huyser Attorneys’ general litigation practice handles personal-injury and professional-negligence claims across Gauteng; the practical first point of contact is the Linden head office on 011 888 0246 (after-hours 061 516 6878).
