Why German Buyers Ask Different Questions About Warranty
German investors and developers approaching Turkish real estate tend to carry a specific expectation into the process: that structural and workmanship defects will be covered by a clear, enforceable warranty regime, similar to the VOB/B framework and BGB Werkvertragsrecht that governs German construction contracts. Türkiye's system is built on different legal foundations, and understanding the gap before signing a purchase or construction contract is essential, not optional.
This matters more in Türkiye than in most markets because of seismic risk. A warranty and defects-liability structure is not just a commercial safeguard here, it is tied directly to structural safety assurance in an earthquake-prone country.
The Legal Basis: Turkish Code of Obligations
Construction defect liability in Türkiye is primarily governed by the Turkish Code of Obligations (Türk Borçlar Kanunu), particularly the provisions on eser sözleşmesi, the work contract between a contractor (müteahhit) and an employer or buyer. Under this framework, a contractor is liable for defects that existed at the time of delivery, including hidden defects that only become apparent later.
For residential and commercial buildings specifically, Turkish law sets a general structural liability period of fifteen years for major structural defects, which is longer than what many German buyers initially expect. This period applies to load-bearing elements, foundation issues, and defects that compromise structural integrity. Non-structural defects, such as finishing work, installations, and fixtures, typically fall under shorter liability windows negotiated in the sales or construction contract, often between two and five years depending on the item.
Important distinction : this statutory framework applies to the relationship between contractor and developer or buyer. When a foreign investor purchases a completed unit from a developer rather than commissioning direct construction, the practical warranty exposure runs through the developer's sales contract and any separate manufacturer or subcontractor warranties on installations, elevators, HVAC systems, and similar components.
Where German Expectations and Turkish Practice Diverge
German contracting culture places heavy weight on written acceptance protocols, the Abnahme process, with detailed punch lists and formal sign-off before liability periods begin running. In Türkiye, iskan (occupancy permit) issuance and delivery documentation serve a related but not identical function. Buyers accustomed to a rigorous Abnahme should insist contractually on an equivalent inspection and documentation process before accepting delivery, since Turkish market practice does not automatically default to this standard of formality.
Another divergence involves who bears the burden of proof. In several respects, Turkish law places the burden on the buyer to demonstrate that a defect existed at delivery rather than arising from subsequent use or lack of maintenance, particularly once time has passed. Contractual clauses addressing inspection timing, notice periods, and documentation requirements should be negotiated up front rather than left to statutory default.
Practical Steps Before Signing
Contract review : Have the sales or construction contract reviewed specifically for defects-liability clauses, warranty periods per component category, and notice procedures, rather than relying on general assurances from a sales team.
Independent technical inspection : Commission an independent structural and MEP inspection at delivery, documented in writing, creating a baseline record separate from the developer's own handover paperwork.
Insurance layering : Understand that DASK earthquake insurance addresses catastrophic loss, not construction workmanship, so a separate defects or professional liability coverage discussion with the developer or contractor is a distinct matter.
Escrow or retention mechanisms : Where feasible, negotiate a retention or holdback on final payment tied to resolution of any snagging list items identified at delivery, a mechanism German buyers will recognize from domestic practice but which requires explicit contractual language in Türkiye rather than assumption.
The Advisory Role
For German investors and developers, the gap between expectation and Turkish statutory default is rarely about the law being weaker, the fifteen-year structural liability period is in fact longer than many European equivalents. The gap is about process discipline: documentation, inspection timing, and contractual specificity that Turkish market practice does not always supply by default. Structuring these protections into the contract before signing, rather than relying on statutory minimums after the fact, is the difference between a warranty that exists on paper and one that is enforceable in practice.
