How Long Do Foreign Patients Have to File a Medical Malpractice Claim in Turkey?

One of the most dangerous mistakes a foreign patient can make after suspected medical malpractice in Turkey is to assume that there is one universal deadline for every medical negligence claim.

There is not.

Depending on the circumstances, a Turkish medical malpractice dispute may involve a five-year contractual limitation period, a two-year and ten-year tort limitation system, a two-year defective-service period, special rules for aesthetic procedures, a longer criminal-law limitation period, or strict one-year and five-year preliminary deadlines for claims involving public hospitals.

Choosing the wrong limitation period can destroy an otherwise strong medical malpractice case.

This is particularly important for international patients.

A patient may return to the United Kingdom, Germany, France, the Netherlands, Belgium, Ireland, the United States, Canada, Australia or another country after treatment in Turkey.

The patient may spend months undergoing corrective treatment.

A clinic may repeatedly say:

“Wait until the swelling disappears.”

“The final result takes twelve months.”

“Come back next year and we will revise the operation.”

“Our insurance department is investigating.”

Meanwhile, a Turkish limitation period may continue running.

The correct deadline depends on questions such as:

• Was treatment provided by a private hospital or state hospital?
• Was the claim based on ordinary medical negligence?
• Does the patient rely on contract, tort or both?
• Was the procedure purely aesthetic and result-oriented?
• Is the claim based on defective consumer service?
• Could the healthcare professional’s conduct also constitute a criminal offence?
• When did the damage become legally identifiable?
• Was mediation initiated?
• Has a lawsuit already been filed?
• Has the healthcare provider acknowledged liability or made a relevant payment?

For this reason, the safest answer to:

“How long do I have to sue a hospital in Turkey?”

is:

The legal relationship must be classified before the deadline can be calculated.

This article explains the principal limitation periods that foreign patients should know.

Quick Overview of Medical Malpractice Deadlines in Turkey

The following summary is only a starting point.

These periods can overlap.

A single medical incident may potentially create several different legal bases.

That is why a patient should not calculate the deadline by simply selecting the longest number appearing on an internet page.

Does Foreign Nationality Change the Limitation Period?

Generally, no special shorter limitation period applies merely because the patient is foreign.

A British, German, Dutch, French, American or other international patient is not automatically required to sue more quickly than a Turkish patient simply because of nationality.

What matters is the legal nature of the healthcare relationship.

For example:

A British patient receiving ordinary surgery in a private Turkish hospital may face the same contractual classification issues as a Turkish private-hospital patient.

A German patient receiving aesthetic surgery may be subject to the rules governing result-oriented aesthetic treatment.

A foreign patient treated in a Turkish state hospital may need to comply with the same administrative preliminary-application structure applicable to public healthcare liability.

The international element can affect matters such as jurisdiction, service, evidence and applicable private-international-law rules, but nationality alone does not create a universal foreign-patient malpractice limitation period.

Private Hospital Malpractice: Is the Deadline Five Years or Ten Years?

This is one of the most important areas of confusion.

It is frequently stated online that contractual medical malpractice claims against private hospitals are automatically subject to a ten-year general limitation period.

That statement is too broad.

Article 146 of the Turkish Code of Obligations does provide a general ten-year limitation period where the law does not prescribe another period.

However, Article 147 expressly provides a five-year limitation period for claims arising from mandate agreements.

This distinction matters because Turkish Court of Cassation jurisprudence commonly characterises the ordinary private doctor–patient and private hospital–patient treatment relationship through the rules governing mandate — vekâlet.

Important Court of Cassation Decision: Five Years for an Ordinary Private Medical Malpractice Contract

A particularly useful recent authority is Court of Cassation 3rd Civil Chamber, E. 2023/2982, K. 2024/3055, dated 14 October 2024.

The case concerned alleged incorrect medical diagnosis and treatment.

The lower courts had treated the contractual claim as subject to a ten-year limitation period.

The Court of Cassation corrected that reasoning.

It held that the doctor/private hospital and patient relationship was a mandate relationship and that the applicable limitation period under Article 147 was five years, rather than the general ten-year period.

The underlying operation had occurred on 27 October 2011 and the action was brought on 22 December 2021, so the Court concluded that the five-year contractual period had expired.

This decision is extremely important for current medical malpractice analysis.

Foreign patients should therefore not rely on the statement:

“It was a contract, so I definitely have ten years.”

For an ordinary private medical-treatment relationship characterised as mandate, the current Court of Cassation approach can result in a five-year period.

When Does the Five-Year Contractual Period Start?

The starting point requires individual analysis.

Under Turkish obligations law, limitation generally begins when the claim becomes due.

Therefore, determining the exact date may require consideration of:

• date of treatment;
• date of operation;
• completion of an ongoing course of treatment;
• nature of the alleged contractual breach;
• when the particular compensation claim became due.

In the 14 October 2024 Court of Cassation malpractice decision, the date of the relevant operation was treated as material when assessing whether the five-year period had expired.

However, patients should avoid creating an absolute rule that every medical claim begins on the date they entered the hospital.

A continuing treatment relationship, later intervention or different contractual obligation may require separate analysis.

What If the Patient Did Not Discover the Malpractice for Several Years?

This is where the distinction between contractual liability and tort liability becomes extremely important.

A patient may not immediately know that malpractice occurred.

For example:

A patient undergoes surgery in 2024.

The patient experiences pain but is repeatedly told that recovery is normal.

In 2027, another surgeon identifies a retained surgical problem or permanent injury resulting from the original operation.

A contractual limitation analysis and a tort limitation analysis may produce different questions.

The patient should therefore not assume that late discovery automatically restarts every limitation period.

Instead, the lawyer should examine whether tort rules, contractual rules or another legal basis is more favourable and legally available.

Tort-Based Medical Malpractice: The Two-Year and Ten-Year Rule

Article 72 of the Turkish Code of Obligations provides the principal limitation system for tort claims.

A compensation claim generally becomes time-barred:

two years after the injured person learns both the damage and the person responsible, and

in any event ten years after the wrongful act.

These are often described as:

the subjective period, and

the objective maximum period.

The two-year period does not necessarily begin simply because the patient feels pain.

The legally relevant question is when the patient can be regarded as having sufficient knowledge of the damage and person responsible.

Example: Late Discovery of Permanent Injury

Suppose a foreign patient undergoes surgery in Turkey in January 2025.

The patient continues to experience neurological symptoms.

The Turkish clinic repeatedly states that they will resolve naturally.

In March 2027, a specialist in Germany concludes that permanent nerve damage was caused by the 2025 operation.

For a tort claim, the date on which the patient legally learned the damage and responsible person may become highly relevant to the two-year subjective limitation period.

However, Article 72 also contains an objective long-stop period measured from the wrongful act.

The patient cannot therefore assume that delayed discovery creates unlimited time.

Permanent Disability Can Affect the “Knowledge” Analysis

Turkish Court of Cassation jurisprudence has recognised in some bodily-injury cases that the date on which the injury becomes sufficiently definite can be significant when identifying when the claimant learned the full damage.

A 2024 decision of the Court of Cassation General Assembly discussing bodily injury and limitation emphasised the difference between the subjective period based on learning the damage and liable party and the objective period calculated from the wrongful act.

Medical injuries frequently evolve over time.

A temporary symptom and an established permanent disability are not always the same thing.

Nevertheless, a patient should never deliberately wait for a final disability report without obtaining limitation advice.

What If the Medical Error Also Constitutes a Criminal Offence?

Article 72 contains one of the most important exceptions to the ordinary tort limitation periods.

If the compensation claim arises from conduct that constitutes a criminal offence and criminal law provides a longer limitation period, that longer period applies to the compensation claim.

This can substantially extend the period available in serious malpractice cases.

Potentially relevant offences can include:

• negligent injury;
• negligent homicide.

However, the legal characterisation must be assessed carefully.

Not every medical complication constitutes a crime.

A Criminal Conviction Is Not Necessarily Required for the Longer Period

A major Court of Cassation General Assembly decision is especially important.

In E. 2017/778, K. 2019/329, the General Assembly considered medical malpractice where the doctor–patient relationship was contractual but the alleged conduct also had the characteristics of negligent criminal injury.

The Court accepted that contractual and tort responsibility could coexist and that the longer criminal-law limitation rule could benefit the patient.

Crucially, the Court stated that applying the longer period did not necessarily require the doctor actually to have been convicted; it was sufficient for the relevant conduct to have the legal character of a criminal offence.

This can be highly important where the ordinary five-year contractual period appears to have expired.

But it does not mean every old medical case can automatically be revived by alleging a crime.

The conduct must legally satisfy the relevant criminal offence.

Negligent Injury and the Longer Criminal Limitation Period

Medical malpractice causing bodily injury can potentially fall within Article 89 of the Turkish Criminal Code concerning negligent injury, depending on the circumstances.

Article 89 was amended effective in late 2025. The current provision provides criminal penalties for negligently causing bodily pain or impairment of health or perception and increases the consequences for specified serious injuries.

Article 66 of the Criminal Code determines criminal prosecution limitation periods according to the maximum statutory penalty.

For offences punishable by no more than five years’ imprisonment or a judicial fine, the basic criminal prosecution limitation category is eight years.

Accordingly, many negligent-injury malpractice scenarios can raise an eight-year criminal limitation analysis.

However, offence date, statutory version, degree of injury, conscious negligence and other criminal-law issues can affect the calculation.

A medical malpractice lawyer should therefore calculate the exact period rather than assuming that every injury claim has eight years.

Fatal Medical Negligence Can Produce a Longer Period

Where negligent medical conduct causes death, Article 85 of the Turkish Criminal Code concerning negligent homicide may become relevant.

For causing the death of one person, Article 85 provides imprisonment of two to six years. Where the conduct causes multiple deaths or death together with injury to one or more persons, the statutory maximum can be considerably higher.

Under Article 66, offences punishable by more than five but less than twenty years’ imprisonment generally fall within a fifteen-year criminal prosecution limitation category.

Consequently, a fatal medical malpractice case can potentially involve a substantially longer limitation period than an ordinary contractual claim.

Again, this must be assessed according to the exact criminal character of the conduct.

Filing a Criminal Complaint and Filing a Compensation Claim Are Not the Same Thing

Foreign patients should be careful here.

A family may file a criminal complaint against a doctor and assume:

“Now our compensation case is protected.”

That assumption should not be made automatically.

A criminal investigation and a civil compensation claim are different proceedings.

The fact that a longer criminal limitation period may apply to a tort claim is not the same thing as saying that filing a criminal complaint automatically replaces filing the civil claim.

The compensation deadline should still be independently calculated and preserved.

Consumer Law: A Two-Year Period for Defective Medical Services

Private medical treatment may also fall within Turkish consumer law where the legal relationship qualifies as a consumer transaction.

Article 16 of Consumer Protection Law No. 6502 provides that liability for a defective service is generally subject to a two-year limitation period from performance of the service, even if the defect appears later, unless another law or contract provides a longer period.

Article 16 also provides an important exception:

Where the defect was concealed through gross fault or fraud, the ordinary limitation provisions do not apply in the same way.

This can be relevant to claims concerning:

• incomplete treatment;
• failed dental work;
• materially different treatment from what was promised;
• defective medical-tourism services;
• certain refund claims.

Consumer Limitation and Medical Malpractice Limitation Are Not Always the Same

A patient may have several potential causes of action arising from the same treatment.

For example:

A dental treatment dispute could involve:

• defective service under consumer law;
• contract-for-work rules;
• bodily injury;
• tort;
• informed consent.

Each legal basis may have different limitation consequences.

Therefore, the existence of the two-year consumer period does not necessarily mean that every possible compensation claim disappears exactly two years after treatment.

Likewise, the existence of another potentially longer period does not necessarily save every defective-service remedy.

The causes of action must be classified separately.

Cosmetic Surgery and Aesthetic Treatment: Special Works-Contract Rules

Purely aesthetic, result-oriented treatment can create a different legal structure.

Turkish Court of Cassation jurisprudence frequently treats procedures such as certain cosmetic surgeries and aesthetic dental treatments as contracts for work — eser sözleşmesi because the provider undertakes an agreed result rather than merely promising professional effort.

This matters for limitation.

Article 478 of the Turkish Code of Obligations specifically regulates claims arising from a defective work.

For works other than immovable structures, claims arising from the defective work are generally time-barred two years after delivery.

Where the contractor is grossly at fault, the period can be twenty years, regardless of the nature of the work.

This can be highly relevant to claims concerning:

• failed cosmetic surgery;
• defective aesthetic dental work;
• other result-oriented medical procedures.

Do All Aesthetic Claims Have Exactly Two Years?

No.

This is another area where oversimplification can be dangerous.

Article 478 specifically concerns claims based on the contractor creating a defective work.

Article 147 also contains a general five-year rule for claims arising from works contracts, except where the contractor has failed to perform properly because of gross fault.

Accordingly, a legal analysis should identify:

• the exact contractual claim;
• whether it is specifically a defect claim;
• whether gross fault is alleged and established;
• whether tort or consumer-law responsibility also exists.

A website statement saying:

“All cosmetic surgery cases must be filed within two years”

would therefore be too broad.

Cosmetic Patients Should Also Consider the Duty to Notify Defects

Limitation is not the only time-sensitive issue in a works-contract dispute.

Article 477 of the Turkish Code of Obligations contains rules concerning inspection, acceptance and notifying defects.

If a defect appears later, the customer is expected to notify the contractor without delay; failure to do so can produce consequences concerning acceptance of the work.

For a foreign cosmetic patient, this means that even where the formal limitation period has not expired, remaining silent for a long time after discovering a defect can create separate legal problems.

The patient should therefore preserve written complaints made to the clinic.

Public Hospital Malpractice: Much Stricter Administrative Deadlines

Claims involving state hospitals require a fundamentally different analysis.

A public-hospital malpractice claim generally proceeds within administrative jurisdiction as a claim based on allegedly defective public healthcare service.

Article 13 of the Administrative Procedure Law No. 2577 provides a strict preliminary application requirement.

A person whose rights have been infringed by an administrative act or conduct must generally apply to the relevant administration:

within one year from learning of the administrative conduct, and

in any event within five years from the conduct, requesting compensation or restoration of the right.

This is extremely important.

The patient does not simply wait five years and file directly in court.

A prior application to the administration is part of the statutory structure.

What Happens After the Administrative Application?

If the administration:

• rejects the request in whole or in part; or
• does not respond within 30 days,

the patient may then file the full-remedy action within the applicable administrative litigation period.

Article 7 of the Administrative Procedure Law provides a general 60-day period for actions before administrative courts, unless a special provision applies.

The calculation therefore has several stages.

A public-hospital case should not be approached using the private-hospital five-year contractual rule.

Example of a State Hospital Deadline

Suppose a foreign patient suffers serious injury during treatment at a Turkish state hospital.

The patient learns on 1 February 2026 that the injury was allegedly caused by deficient healthcare.

Under Article 13, the date on which the patient learned of the relevant administrative conduct can become critical to the one-year preliminary-application period.

The patient should not simply assume:

“The overall maximum is five years, so I can wait four years.”

The one-year subjective period may already create a much earlier deadline.

What If the Administration Does Not Answer?

Article 13 currently provides that if no answer is received within 30 days, the patient may proceed according to the litigation-period rules after that period expires.

Therefore, foreign patients should carefully record:

• date the application was submitted;
• date it was received by the administration;
• date any rejection was served;
• date the 30-day silence period expired.

Administrative litigation is highly sensitive to dates.

Are University Hospitals Public or Private?

Do not determine the deadline merely because the institution’s name contains the words:

“University Hospital.”

The legal status of the healthcare provider must be identified.

A public university hospital and a healthcare institution connected with a private foundation university may produce different jurisdictional and procedural consequences.

Before calculating any limitation period, identify the exact legal entity operating the hospital.

Does Requesting Medical Records Stop the Malpractice Limitation Period?

Do not assume so.

A patient may submit:

• a medical-record request;
• a Patient Rights complaint;
• a KVKK personal-data request.

Those procedures can be extremely useful for obtaining evidence.

But they should not automatically be treated as suspending or interrupting the separate limitation period governing the compensation claim.

A patient should therefore collect records and calculate the malpractice deadline simultaneously.

Do not wait for a hospital to spend months producing records before checking whether the compensation period is approaching expiry.

Does Sending a Lawyer’s Demand Letter Stop Limitation?

Again, do not assume so.

Article 154 of the Turkish Code of Obligations specifically identifies events that interrupt limitation.

These include circumstances such as:

• the debtor acknowledging the debt;
• the creditor bringing a claim before a court or arbitrator;
• commencing enforcement proceedings;
• applying to the bankruptcy estate.

A simple demand letter is not itself listed as the equivalent of filing a lawsuit.

Therefore, sending:

“Please pay compensation within seven days”

should not be relied upon as though it automatically preserves the claim indefinitely.

What If the Hospital Admits Responsibility?

A legally sufficient acknowledgment by the debtor can interrupt limitation under Article 154.

The statute specifically refers to acknowledgment and gives examples such as partial performance.

But not every statement by a clinic amounts to legal acknowledgment.

For example:

“We are sorry you are unhappy.”

is not necessarily the same as:

“We accept legal liability for the injury and will pay the damage.”

The wording and circumstances matter.

Foreign patients should therefore preserve settlement communications but should not assume that polite communication restarted the limitation period.

Does Filing a Lawsuit Interrupt Limitation?

Yes.

Article 154 provides that applying to a court or arbitrator, or commencing specified formal proceedings, interrupts the limitation period.

This is one reason why waiting until the final days of a limitation period can be dangerous.

The correct defendant and claim should ideally be identified before urgent filing becomes necessary.

What Happens During Mandatory Mediation?

Many private healthcare disputes that qualify as consumer disputes require mandatory mediation before Consumer Court litigation.

This raises an important limitation question.

Under Article 18/A of the Mediation Law, from the date of application to the mediation bureau until the date of the final mediation record, limitation is suspended and limitation-type deadlines do not run.

The general mediation legislation similarly provides that time spent in the mediation process is not counted when calculating limitation and forfeiture periods.

This is valuable protection.

But it should not encourage patients to wait until the last day.

Example: Limitation During Consumer Mediation

Suppose a patient has only 20 days remaining in the applicable limitation period.

Mandatory consumer mediation is properly initiated.

The time during the statutory mediation process is not counted against the claimant in the manner provided by the Mediation Law.

Once the mediation ends, the remaining limitation analysis must be handled promptly.

A patient should keep:

• mediation application date;
• mediator appointment documentation;
• final record date.

Clinic Negotiations Are Not the Same as Formal Mediation

There is an important distinction between:

formal statutory mediation, and

informal negotiation with the clinic.

WhatsApp discussions such as:

“We may offer you a partial refund.”

do not automatically create the same statutory limitation protection as formal mandatory mediation.

A patient can continue negotiating while simultaneously taking the formal steps necessary to protect the claim.

What If the Clinic Keeps Saying “Wait 12 Months for the Final Result”?

This is particularly common after aesthetic surgery.

Clinically, waiting can sometimes be reasonable.

For example:

• rhinoplasty swelling can take substantial time to resolve;
• scars evolve;
• hair transplant results develop gradually.

But medical waiting periods and legal limitation periods are not automatically the same.

The correct strategy may be:

wait medically for the final result, but protect the legal claim in the meantime.

A foreign patient should not rely on a clinic’s medical advice about healing as legal advice about limitation.

What If Revision Surgery Is Performed Later?

A revision procedure may create complex limitation questions.

Possible issues include:

• whether the revision forms part of continuing treatment;
• whether it amounts to acknowledgment of defective performance;
• whether a new wrongful act occurred;
• whether the original claim was already time-barred.

A free revision surgery does not automatically mean that every limitation period begins again from zero.

The specific facts need legal analysis.

Does Leaving Turkey Affect the Deadline?

Normally, simply returning home does not stop the Turkish limitation period.

The clock does not freeze because the patient lives abroad.

A patient may be recovering in London, Berlin or Amsterdam while the Turkish deadline continues running.

This is why international patients should seek Turkish limitation advice early, even if they have no immediate intention of travelling back.

Can a Foreign Patient File the Case Without Returning to Turkey?

Potentially, yes.

A foreign patient may generally explore appointing Turkish counsel through an appropriate power of attorney.

Depending on the country, the power of attorney may be arranged through:

• a Turkish consulate;
• or an appropriate local notarial and authentication procedure.

Turkish counsel may then potentially:

• request records;
• initiate mediation;
• submit the public-administration application where appropriate;
• file the compensation claim;
• follow expert proceedings.

Accordingly, physical distance from Turkey should not be used as a reason to allow a limitation period to expire.

What If the Patient Dies?

Where alleged malpractice results in death, surviving relatives may have independent compensation rights.

The applicable limitation analysis can differ according to:

• tort;
• support-loss compensation;
• criminal character of the underlying conduct;
• public or private healthcare provider.

Because negligent homicide can potentially carry a longer criminal limitation period, fatal medical malpractice cases should be reviewed specifically rather than applying the ordinary private-hospital contractual period mechanically.

What If the Patient Is Still Receiving Treatment?

Do not assume that all limitation periods necessarily wait until every follow-up appointment is completed.

The question depends on the specific legal obligation and claim.

The treatment relationship may be continuing, but a particular wrongful intervention may already have occurred.

For example:

A negligent surgical act may occur in January.

The clinic may provide follow-up care until June.

Whether the relevant claim became due in January or later can require analysis of the contractual structure and treatment course.

This is another reason why the exact dates should be reviewed rather than applying a general formula.

The Date of “Learning the Damage” Can Be Disputed

In tort claims, the two-year period depends on learning the damage and liable person.

This can become one of the principal issues in litigation.

The provider may argue:

“The patient knew immediately after surgery that something was wrong.”

The patient may argue:

“I knew I had symptoms, but I did not know that they represented permanent damage caused by the operation until an independent specialist diagnosed it.”

The court then evaluates the evidence.

Relevant documents may include:

• postoperative clinic messages;
• foreign specialist reports;
• disability reports;
• radiological findings;
• correspondence showing what the clinic told the patient.

Patients should preserve this chronology.

Ten Years Is Not Automatically the Deadline for Every Tort Claim

Another common misunderstanding is:

“TBK Article 72 says ten years, so I always have ten years.”

Incorrect.

Article 72 normally includes both:

a two-year subjective limitation period, and

a ten-year objective maximum period.

If the patient learns the damage and responsible person but then waits more than two years without preserving the claim, the existence of the ten-year maximum does not automatically save the action.

The longer criminal limitation rule may change the result where its conditions exist, but that must be established separately.

Five Years Is Not Automatically the Deadline for Every Private Hospital Claim Either

The Court of Cassation’s mandate-based five-year approach is highly important, but it should not be converted into another universal rule.

Private healthcare cases can involve:

• mandate liability;
• tort liability;
• consumer defective-service liability;
• works-contract liability;
• criminally relevant conduct;
• several of these simultaneously.

The same factual event may therefore need to be evaluated under competing legal bases.

Why Early Legal Classification Matters

Imagine three foreign patients who all received treatment at private hospitals on the same date.

Patient A underwent medically necessary surgery and alleges technical negligence.

Patient B underwent purely aesthetic surgery and alleges a defective promised result.

Patient C suffered a severe injury potentially constituting negligent criminal injury.

All three were treated on the same date.

Their limitation analyses may nevertheless differ because the legal bases differ.

That is why counting years before identifying the cause of action is backwards.

First classify the claim.

Then calculate the limitation period.

Practical Deadline Checklist for Foreign Patients

When suspected malpractice occurs, record the following dates immediately:

1. Date treatment began.
2. Date of operation or disputed intervention.
3. Date treatment ended.
4. Date complication first appeared.
5. Date the patient first complained.
6. Date another doctor identified possible malpractice.
7. Date permanent injury was diagnosed.
8. Date medical records were requested.
9. Date a formal demand was sent.
10. Date mediation was initiated.
11. Date mediation ended.
12. Date any administrative application was filed.
13. Date the administration rejected the claim.
14. Date a lawsuit or other formal proceeding was started.

The lawyer can then construct a legal limitation timeline.

Example 1: Private Hospital Surgical Negligence

A patient undergoes non-aesthetic surgery at a private hospital.

The relationship is characterised as mandate.

Current Court of Cassation authority confirms that Article 147/5 can produce a five-year contractual period rather than the general ten-year period.

However, if the alleged conduct also constitutes tort or a criminal offence, alternative limitation rules may also need to be considered.

Example 2: Cosmetic Surgery With a Defective Result

A patient undergoes purely aesthetic surgery.

The relationship is treated as a contract for work.

For a claim specifically arising from a defective result, Article 478 may create:

two years from delivery, or

twenty years where the contractor is grossly at fault.

Consumer and tort claims may require separate analysis.

Example 3: Malpractice Discovered Years Later

A patient undergoes surgery in 2025 but learns in 2028 that permanent injury was caused by the operation.

A tort claim may raise Article 72’s two-year period from learning the damage and responsible person, subject to the ten-year maximum and any longer criminal limitation rule.

The contractual claim requires its own analysis and should not automatically be assumed to start only in 2028.

Example 4: Medical Negligence in a State Hospital

A patient suffers harm in a state hospital.

The patient learns the alleged service fault.

Article 13 requires a preliminary application to the administration generally within one year from learning and in any event within five years from the administrative conduct.

After rejection or statutory silence, the separate administrative court filing period becomes critical.

This is substantially different from a private-hospital damages claim.

Example 5: Fatal Medical Negligence

A patient dies following allegedly negligent treatment.

The family’s claim may involve support-loss and moral damages.

Where the underlying medical conduct has the characteristics of negligent homicide, the longer criminal-law limitation mechanism under Article 72 should be evaluated.

A fatal case should therefore not automatically be dismissed merely because more than five years have passed without examining the potentially applicable tort and criminal limitation rules.

Frequently Asked Questions

How long do I have to sue a private hospital for medical malpractice in Turkey?

There is no single answer, but ordinary private doctor/private hospital treatment relationships are commonly treated as mandate contracts. Article 147/5 provides a five-year limitation period for mandate claims, and the Court of Cassation specifically applied that five-year period in a 2024 medical malpractice case.

Is the limitation period always ten years?

No. Article 146 contains the general ten-year rule, but special provisions apply to mandate, defective service, works contracts and tort claims.

What is the tort limitation period?

Article 72 generally provides two years from learning the damage and liable person and an objective ten-year period from the wrongful act. A longer criminal limitation period applies where the conduct constitutes an offence subject to a longer period.

What if the doctor committed a criminal offence?

Where the conditions of Article 72 are satisfied, the longer criminal limitation period can apply. Court of Cassation General Assembly jurisprudence confirms that an actual criminal conviction is not necessarily required if the conduct legally constitutes the relevant offence.

How long is the limitation period for negligent medical injury?

Depending on the exact criminal classification, many negligent-injury cases can fall within the eight-year criminal prosecution limitation category. The precise calculation depends on the statutory offence and circumstances.

How long after fatal medical negligence?

Where negligent homicide under Article 85 is applicable, the criminal limitation analysis can lead to a significantly longer period, commonly within the fifteen-year category under Article 66.

How long do I have for a defective healthcare service under consumer law?

Article 16 generally provides two years from performance of the service unless another law or contract provides a longer period. The statute treats defects concealed by gross fault or fraud differently.

How long for failed cosmetic surgery?

Where a result-oriented aesthetic procedure is legally treated as a works contract and the claim concerns a defective work, Article 478 generally provides two years from delivery and twenty years where the contractor is grossly at fault. Other legal bases may produce different limitation questions.

How long do I have against a state hospital?

Article 13 generally requires the patient to apply first to the responsible administration within one year from learning of the administrative conduct and in any event within five years of the conduct.

How long after the administration rejects my claim?

The administrative court litigation period then becomes critical. Article 7 generally provides a 60-day period in administrative courts unless a special rule applies.

Does requesting medical records stop limitation?

Do not assume so. A records request should not be relied upon as a substitute for taking the formal steps necessary to preserve the compensation claim.

Does sending a legal notice stop limitation?

A simple demand should not automatically be treated as interrupting limitation. Article 154 identifies particular interruption events such as acknowledgment of debt and formal court, arbitration or enforcement proceedings.

Does mandatory mediation stop the clock?

In mandatory mediation, the period from application to the mediation bureau until the final record is issued is not counted in the manner specified by Article 18/A.

Does a criminal complaint automatically protect my compensation case?

Do not assume so. Criminal and compensation proceedings are distinct. The civil limitation analysis should be performed separately.

Does returning to my own country stop the Turkish limitation period?

Generally no. Physical absence from Turkey should not be assumed to suspend the applicable malpractice deadline.

Can I start proceedings without returning to Turkey?

Potentially, yes. Foreign patients can generally explore appointing appropriately authorised Turkish counsel to take the necessary procedural steps.

Conclusion: There Is No Single Medical Malpractice Limitation Period in Turkey

The most important rule for foreign patients is simple:

Do not ask only, “How many years do I have?”

First ask:

“What type of legal claim do I have?”

Turkish medical malpractice cases can be based on different legal relationships, and each relationship can produce a different limitation calculation.

For ordinary medical treatment at a private hospital, current Court of Cassation authority is especially important.

In its 14 October 2024 decision, E. 2023/2982, K. 2024/3055, the Court of Cassation held that the doctor/private hospital–patient relationship was governed by mandate principles and that the applicable contractual limitation period was five years under Article 147, not the general ten-year period.

This means that a foreign patient should not rely on online statements saying:

“Private medical malpractice always has a ten-year limitation period.”

Article 146’s ten-year rule is a general residual rule.

Article 147 contains shorter specific periods, including five years for claims arising from mandate agreements.

Tort claims follow a different structure.

Under Article 72, the ordinary periods are:

two years from learning the damage and responsible person, and

ten years from the wrongful act in any event.

Where the healthcare professional’s conduct also legally constitutes a criminal offence subject to a longer limitation period, that longer criminal period can apply.

Court of Cassation General Assembly jurisprudence confirms that this protection can operate in a medical malpractice dispute even where the parties also have a contractual relationship and that an actual criminal conviction is not necessarily required before the longer period can become relevant.

This can be particularly important in cases of serious bodily injury or death.

Negligent injury under Article 89 may result in an eight-year criminal limitation analysis in many ordinary cases, while negligent homicide under Article 85 can produce a substantially longer limitation period falling within the fifteen-year category under Article 66, depending on the precise offence.

Consumer law creates another layer.

Where the dispute concerns a defective healthcare service, Article 16 of Consumer Protection Law generally provides two years from performance of the service, unless a longer period applies. Defects concealed through gross fault or fraud are subject to the statutory exception.

Aesthetic procedures require still another analysis.

Where a cosmetic or other result-oriented treatment constitutes a contract for work and the claim specifically concerns a defective work, Article 478 provides a general two-year period from delivery for non-immovable work and a twenty-year period where the contractor is grossly at fault.

Public hospitals operate under an entirely different procedural system.

Article 13 of the Administrative Procedure Law requires a prior application to the administration generally:

within one year from learning of the administrative conduct, and

in any event within five years of that conduct.

Where the claim is rejected or no response is given within the statutory 30-day period, the patient must then pay close attention to the separate administrative court filing period, which is generally 60 days under Article 7 unless another special rule applies.

These public-hospital deadlines are particularly dangerous for international patients because a person can lose time while undergoing treatment abroad without appreciating that the preliminary administrative application itself is subject to a one-year subjective deadline.

Foreign patients should also understand what does not necessarily protect the deadline.

Repeated WhatsApp negotiations with the clinic are not formal litigation.

Requesting medical records should not be assumed to stop the compensation limitation period.

Sending a lawyer’s demand letter does not automatically have the same legal effect as filing an action.

Article 154 specifically regulates events interrupting limitation, including acknowledgment by the debtor and formal applications to courts, arbitrators and specified enforcement procedures.

Mandatory mediation is different.

Where mediation is legally required before the consumer lawsuit, Article 18/A provides that limitation is suspended from the mediation application until the final record is prepared.

The practical lesson for international patients is therefore to create a legal timeline as soon as serious malpractice is suspected.

Record:

the date of treatment,

the operation date,

the date symptoms began,

the date malpractice was first suspected,

the date an independent doctor identified the injury,

the date permanent disability became clear,

the date the hospital was formally contacted,

and every mediation, administrative or judicial filing date.

A Turkish lawyer can then determine which limitation regime or combination of regimes applies.

The most dangerous approach is to rely on the longest possible period and postpone action.

A patient may believe there are ten years remaining when the applicable contractual period is five years.

A cosmetic patient may believe the same while a specific defect claim is governed by a much shorter period.

A public-hospital patient may assume there are years remaining when the one-year preliminary administrative-application period is already running.

Conversely, an older medical malpractice case should not automatically be abandoned because five years have passed.

Tort rules, delayed knowledge, criminally relevant conduct, gross fault and competing legal bases may mean that another legally available period remains open.

If you received medical treatment in Turkey and believe that negligence, lack of informed consent, a defective aesthetic procedure or poor complication management caused injury, the limitation period should be calculated before deciding whether the claim is still possible. The hospital type, treatment contract, date of injury, date of discovery and potential criminal character of the medical conduct can all materially change the answer.

Legal Disclaimer

This article provides general information regarding medical malpractice limitation periods under Turkish law as of September 2026. It does not constitute individual legal advice or a definitive limitation calculation for any particular patient.

Limitation periods can depend on the legal classification of the treatment, private or public status of the healthcare institution, contractual structure, type of damage, date of discovery, criminal character of the conduct, mediation history, prior applications and events capable of suspending or interrupting limitation.

A specific medical malpractice file should therefore be reviewed individually before any conclusion is reached that the claim is either in time or time-barred.
