Professional negligence in Türkiye

Claims involving professional advice, technical work and service failures.

Professional-negligence analysis in Türkiye depends on the engagement, applicable professional obligations and the public or private character of the service. A public-service claim may raise an administrative route rather than an ordinary contractual action. Establish the alleged departure, causal link and expert evidence before choosing between compensation, regulatory or disciplinary procedures.

Establish the engagement, responsible professional, expected work and alleged departure from the applicable standard. Compare the actual outcome with the position that competent performance would probably have produced. Preserve the complete file and independent technical evidence. Regulatory complaints, fee disputes and compensation claims have different purposes; insurer notification and limitation issues should be considered before negotiations drift.

How Jurisiti can help

An unsatisfactory outcome does not by itself establish professional negligence. Review the agreed scope, the applicable professional standard and what would probably have happened without the alleged error. Complaints procedures, contractual claims and civil proceedings can offer different remedies and may need to be coordinated without overlooking limitation.

  • Scope of retainer and duty analysis
  • Breach, causation and loss assessment
  • Expert evidence and professional indemnity

Questions about your matter

How do I start a professional negligence enquiry in Türkiye?

Identify the jurisdiction, the people involved, any existing proceeding or deadline, and the result you need. A short chronology and the key documents help define the proposed engagement before local professional arrangements are confirmed.

Can a cross-border matter involve more than one legal system?

Yes. Türkiye may be one part of a wider matter involving another place of residence, contracting party, asset or forum. Applicable law, jurisdiction and enforcement should be assessed separately, using the relevant national and international rules.

Does this guide establish a lawyer-client relationship?

No. An enquiry or use of this guide does not establish an engagement. Conflicts, professional authority, scope, responsibilities and fees must be confirmed before work is undertaken.
