How to Prove Medical Negligence in Malaysia: The Evidence You Need
To prove medical negligence in Malaysia, a patient must show four things on a balance of probabilities: that the doctor or hospital owed a duty of care, that the care fell below the accepted standard, that this breach caused the harm, and that the patient suffered injury or loss as a result. The burden of proof is on the patient.
If you or someone close to you was harmed during treatment, this can feel like a heavy load at a hard time. Each element is proved with evidence that can be gathered step by step: the medical records, an independent medical opinion and your own account of what happened. This guide explains what courts look for.
Key takeaways
- In Malaysia, a medical negligence claimant must prove duty, breach, causation and damage; a poor outcome alone does not prove negligence.
- For diagnosis and treatment, Malaysian courts apply the Bolam test as qualified by Bolitho, as the Federal Court confirmed in Zulhasnimar (2017).
- Causation is often the hardest element: the breach must, more likely than not, have caused or materially contributed to the injury.
- Malaysian courts decide breach and causation on medical evidence, so an independent medical opinion is usually essential.
- Malaysian Medical Council guidance says medical records should be released when the patient asks, and they are the foundation of any claim.

What must you prove in a medical negligence claim?
You must prove four elements: a duty of care, a breach of that duty, causation and damage. If any one of them is missing, the claim fails, even if the others are clear.
Duty is rarely in dispute when a doctor has treated you, although a hospital's responsibility for an independent consultant can be. The real contest is usually over breach, causation and the value of the loss. The table shows the evidence that usually proves each element.
| Element | What it means | Evidence that usually proves it |
|---|---|---|
| Duty of care | The doctor or hospital took on your care | Registration and admission forms, appointment records, bills and receipts |
| Breach | The care fell below the accepted standard | Doctors' and nurses' notes, charts, test results and an independent medical opinion |
| Causation | The breach caused or materially contributed to the harm | A timeline built from the records, imaging, and an independent medical opinion on what proper care would probably have achieved |
| Damage | You suffered injury or loss as a result | Medical reports on your condition and prognosis, receipts, payslips and evidence of care needs |
Treatment carries risks even when the care is proper, so a bad result is a reason to examine the records, not proof in itself. Our medical negligence page explains who can be sued and the compensation available.
Who carries the burden of proof, and how sure must the court be?
The patient carries the burden of proof, and the standard is a balance of probabilities: you must show that your account of what went wrong is more likely than not to be true.
Under the Evidence Act 1950 (Act 56), a fact is proved when the court believes it exists, or considers it so probable that a prudent person would act on the assumption that it does. It is for you to prove that the care fell below standard, not for the doctor to prove that it was proper.
Zulhasnimar bt Hasan Basri & Anor v Dr Kuppu Velumani P & Ors [2017] 5 MLJ 438 shows how this works. The family claimed for a baby's brain injury at birth, arguing that a caesarean section should have been done earlier. The courts below found that the mother was not in labour on admission, so there was no reason for an earlier caesarean and no breach was proved. The Federal Court dismissed the appeal on 25 July 2017.
Nor should you expect the facts to speak for themselves. In Shalini a/p Kanagaratnam v Pusat Perubatan Universiti Malaya & Anor [2016] 3 MLJ 742, the Court of Appeal said the patient must establish the standard of care and prove its breach with medical evidence, so the principle known as res ipsa loquitur will not ordinarily apply.
How do Malaysian courts judge the standard of care?
For diagnosis and treatment, the court asks whether the doctor acted in accordance with a practice accepted as proper by a responsible body of doctors skilled in that field, and whether that practice can withstand logical analysis. This is the Bolam test, from a 1957 English case, as qualified by the House of Lords in Bolitho.
The Federal Court confirmed this approach in Zulhasnimar and applied it in Dr Hari Krishnan & Anor v Megat Noor Ishak bin Megat Ibrahim & Anor [2018] 3 MLJ 281, where a patient lost the sight of one eye after retinal surgery. Three practical points follow.
- The doctor is measured against an ordinary competent doctor in the same field, not against the most skilled.
- A defence opinion that the practice was acceptable does not end the matter. The court can reject an opinion that does not withstand logical analysis, for example one that has not weighed the risks and benefits.
- Where responsible doctors genuinely differ, choosing one accepted approach over another is not negligence by itself.
A different test applies to the duty to warn of risks before treatment. There the court, not the medical profession, decides what should have been disclosed, following the Federal Court in Foo Fio Na v Dr Soo Fook Mun & Anor [2007] 1 MLJ 593, so consent claims are assessed separately.
How do you prove that the negligence caused the injury?
You must show that, more likely than not, the breach caused the injury or materially contributed to it. Courts start with a 'but for' question: would the harm have happened anyway if proper care had been given?
This is often the hardest part of a claim, because many patients were already unwell and the defence will usually say that the illness, not the care, caused the outcome. Your independent medical opinion must explain what would probably have happened with proper care, using the timeline in the records.
A material contribution can be enough. In Nurul Iman Abu Mansor v Gleneagles Hospital Kuala Lumpur Sdn Bhd & Anor (2024), the High Court in Kuala Lumpur found that the defendants' negligence, in cutting a nerve during carpal tunnel surgery and in the delay in identifying and treating it, caused or materially contributed to her injury, which left lasting impairment of her dominant hand.
Delayed diagnosis is harder. If the chance of a good outcome was below 50% even with prompt care, the claim may fail on causation. Some countries award damages for the 'loss of a chance' itself, but the House of Lords refused to do so in Hotson v East Berkshire Area Health Authority (1987) and Gregg v Scott (2005), a delayed cancer diagnosis case. Because Malaysian courts decide causation on a balance of probabilities and often draw on English decisions, a claim should not rest on a lost chance alone.
Why do you need an independent medical opinion?
Because breach and causation are medical questions, a claim almost always needs a written opinion from an independent doctor in the relevant field. Without one, the court has no proper basis to find that the care fell below the accepted standard.
Under section 45 of the Evidence Act 1950, the opinions of persons specially skilled in a science are relevant facts. Order 40A of the Rules of Court 2012 requires this evidence to be given in a written report that sets out the doctor's qualifications, summarises the conclusions and states that the doctor's overriding duty is to the court. The opinion must therefore be objective, even though your side pays for it.
A useful opinion usually:
- comes from a doctor practising in the same field as the treating doctor, with no connection to the hospital;
- is based on the complete records, not only on your account;
- explains what an ordinary competent doctor would have done, and why;
- deals separately with causation and with your present condition and prognosis.
The defence will usually call its own medical witnesses. Where the opinions conflict, the judge may prefer one over the other, and will test which is logical and consistent with the records. An early opinion also gives you an honest view of whether the claim is worth pursuing.
How do you get the medical records, and what should you do now?
Ask for the complete records in writing as soon as you can. The Malaysian Medical Council's guideline on medical records and medical reports (MMC Guideline 002/2006) says practitioners should release the records, or certified true copies, when the patient asks, and sets a time frame of six weeks for a medical report.
The guideline treats refusal or undue delay as unethical, and you can complain to the Council. If records are still withheld, you can apply to court for pre-action discovery under Order 24 rule 7A of the Rules of Court 2012, showing that the documents are relevant to the intended claim.
Check that the copies are complete: doctors' and nurses' notes, observation charts, medication and anaesthetic records, test and imaging results, consent forms and discharge summaries. Meanwhile:
- write a dated timeline of what happened and who said what, while memories are fresh;
- keep bills, receipts, photographs, messages and appointment cards;
- note the names of family members or others who were present;
- do not sign a settlement or waiver before taking advice;
- keep the time limit in view: generally six years against private hospitals and doctors in Peninsular Malaysia, and 36 months against government hospitals.

Frequently Asked Questions
What do I need to prove in a medical negligence case in Malaysia?
In a Malaysian medical negligence case, the patient must prove four things on a balance of probabilities: that the doctor or hospital owed a duty of care, that the care fell below the accepted standard, that this breach caused or materially contributed to the injury, and that the patient suffered damage. A poor outcome alone is not enough, because treatment carries risks even when care is proper.
Is a bad outcome after surgery proof of medical negligence in Malaysia?
No. In Malaysia, a poor result after surgery or treatment does not by itself prove medical negligence. The patient must show that the care fell below what a responsible body of doctors in that field would accept, under the Bolam test as qualified by Bolitho, and that this failure caused the harm. The complete medical records and an independent medical opinion are usually needed to show both points.
Do I need an independent medical opinion to sue a doctor in Malaysia?
In practice, yes. Malaysian courts decide breach and causation in medical negligence claims on medical evidence, and the Court of Appeal has said that the patient must prove the breach with such evidence. Under Order 40A of the Rules of Court 2012, the opinion is given in a written report, and the doctor giving it owes an overriding duty to the court, so it must be objective.
What can I do if a hospital in Malaysia will not release my medical records?
The Malaysian Medical Council's guideline on medical records says practitioners should release the records, or certified true copies, when the patient asks, and treats refusal or undue delay with a medical report as unethical. A patient can complain to the Council. If the records are still withheld, the patient can apply to court for pre-action discovery under Order 24 rule 7A of the Rules of Court 2012 before filing a claim.
Can I claim in Malaysia if a delayed diagnosis only reduced my chance of recovery?
It depends on the evidence. In a Malaysian medical negligence claim, causation is decided on a balance of probabilities, so the patient usually needs to show that, with timely diagnosis, a better outcome was more likely than not. Where the chance of a good outcome was already below 50%, the claim may fail. English courts have refused damages for the loss of a chance alone, so such claims need careful assessment.
