Doctor and Physician Legal Liability in Turkey

Doctors in Turkey are held liable for malpractice along three separate tracks: civil (the patient sues for damages), criminal (the prosecutor charges negligent injury or killing), and administrative (a claim against a state or university hospital). These tracks can run at the same time, and which one applies decides the defendant, the court, the deadline and the evidence. This guide explains how each works and what it means for a foreign patient who was harmed by treatment in Turkey.

The three tracks of physician liability in Turkey

Turkish law does not handle medical errors under a single rulebook. Depending on the facts, and on where the doctor practises, a physician can be held responsible along three separate tracks. They can run at the same time and they do not cancel each other out.

• Civil liability — the patient sues for financial (pecuniary) and moral (non-pecuniary) damages under the Turkish Code of Obligations (TBK, Law No. 6098).
• Criminal liability — the public prosecutor pursues the doctor for negligent injury (Art. 89) or negligent killing (Art. 85) under the Turkish Penal Code (TCK, Law No. 5237). Since 2022 this track has a new gate: a prosecutor needs prior permission from the Ministry of Health before opening an investigation (explained below).
• Administrative liability — where the doctor works in a state or university hospital, the claim is brought against the public administration before the administrative courts, not against the doctor personally.

Working out which track applies is the first strategic decision in any malpractice matter. For a side-by-side view of the private versus public route, see the comparison table further down, and for how we run each type of case, see our medical malpractice service page.

Civil liability: mandate contract or work contract

In private healthcare the doctor–patient relationship is contractual. In the absence of a dedicated medical statute, Turkish courts classify that contract in one of two ways, and the classification decides how strictly the doctor is judged.

Mandate (proxy) contracts — most treatment

Most therapeutic care — surgery, diagnosis, medication, ongoing treatment — is treated as a vekalet (mandate) contract under the TBK. The doctor does not promise a cure. The duty is to act with the skill and diligence of a careful professional. The patient must show the doctor fell below that standard.

Work contracts — result-based procedures

Where a specific result is promised — classically aesthetic and cosmetic procedures — the relationship is treated as an eser (work) contract under Articles 470 and following of the TBK. Here the doctor effectively warrants the outcome, so failing to deliver the agreed result is itself a breach. The standard of care for the contractor is set out in Article 471/2 TBK: the conduct expected of a prudent contractor (basiretli yüklenici) following accepted professional and technical rules in the same field. This result-based logic makes aesthetic claims easier for patients to prove than ordinary treatment claims.

The three elements every malpractice claim must prove

To hold a physician civilly liable, three elements must be established cumulatively. If any one is missing, the claim fails.

1. Defect (fault) — the doctor departed from accepted medical, ethical and professional standards. A bad outcome alone is not enough. Medicine carries inherent risk, and a recognised complication that occurred despite proper care is not malpractice.
2. Damage — the patient suffered real harm, whether financial (further treatment, lost income) or moral (pain, suffering, loss of quality of life).
3. Causation — a direct causal link between the defect and the damage. The harm must flow from the error, not from the underlying illness or an unavoidable risk.

In practice the decisive element is expert evidence. Turkish courts rely heavily on reports from the Council of Forensic Medicine (Adli Tıp Kurumu) and from specialist expert panels to decide whether the standard of care was breached and whether that breach caused the harm. Since 2022, provincial health directorates and the Ministry of Health's Professional Responsibility Board also carry out a preliminary examination before any criminal investigation can begin.

Informed consent and the duty to disclose

Even technically perfect treatment can be unlawful if the patient was not properly informed. Under the Regulation on Patient Rights (Hasta Hakları Yönetmeliği), the Regulation on Medical Deontology (Tıbbi Deontoloji Nizamnamesi) and Turkish Medical Association ethics rules, a doctor must explain the proposed intervention, its alternatives and its foreseeable complications, and obtain the patient's informed consent before proceeding.

If valid informed consent is missing, the intervention is treated as an unlawful interference with bodily integrity — protected under the Turkish Civil Code (TMK, Law No. 4721, Arts. 23–24) — and the doctor can be liable even where the procedure itself was carried out competently. For foreign patients, consent forms signed only in Turkish, or rushed pre-operative briefings with no interpreter, are a recurring problem; a consent form you could not read is weak evidence of real consent. We examine this in detail in our guide on the physician's responsibility in obtaining consent.

Criminal liability and the Professional Responsibility Board

A medical error can also be a crime. Where a doctor's conduct amounts to negligence, the prosecutor may charge negligent injury (Article 89 TCK) or, in fatal cases, negligent killing (Article 85 TCK) under the Turkish Penal Code (Law No. 5237). Where conduct is intentional or grossly reckless, more serious offences apply. Proceedings follow the Code of Criminal Procedure (CMK, Law No. 5271), and the injured patient can join the case as an intervening party (katılan).

One thing changed dramatically in 2022, and many older guides still get it wrong. A patient can no longer send a complaint straight to the prosecutor and expect an investigation to open automatically.
