Why Warranty Terms Deserve as Much Attention as Price
For Azerbaijani investors and developers entering the Turkish construction market, whether through direct build contracts, joint ventures, or the purchase of newly completed property, warranty and defects liability provisions are frequently treated as boilerplate. In practice, these clauses determine who bears the financial burden when a facade cracks, a roof leaks, or mechanical systems underperform after handover. Azerbaijani parties accustomed to FIDIC-based frameworks in regional infrastructure work will find Türkiye's system familiar in structure but distinct in statutory detail, and the differences matter.
The Statutory Baseline: Turkish Code of Obligations
Türkiye's Code of Obligations (Türk Borçlar Kanunu) imposes a mandatory defects liability regime on construction and works contracts (eser sözleşmesi) that cannot be fully waived by contract. The contractor is responsible for defects that exist at the time of delivery or that emerge as a result of faulty workmanship or materials. Buyers and employers have the right to demand repair, price reduction, or in serious cases, contract rescission. For structural elements, Turkish law also layers on a separate liability regime tied to earthquake-resistant construction standards, given the country's seismic profile, which extends certain contractor and inspector liabilities well beyond ordinary defects periods.
Key point : A generic one-year warranty clause copied from a Gulf or CIS-style contract template will not automatically align with Turkish statutory minimums, and in some cases will conflict with mandatory provisions that override contractual language.
Structural Versus Non-Structural Defects: Different Clocks
Turkish practice distinguishes between minor defects (finishes, fixtures, cosmetic issues) and major structural defects. Non-structural warranty periods in typical developer sales contracts range from two to five years depending on the component, while structural and load-bearing defects can carry liability exposure extending considerably longer, reinforced by building inspection firm (yapı denetim) accountability rules. Azerbaijani investors acquiring completed units or entire buildings should request the building inspection company's file and the structural engineer's sign-off documentation, not just the developer's own warranty certificate, since inspection firm liability runs in parallel to contractor liability.
Contractual Retention and Performance Security
For investors commissioning new construction rather than buying completed stock, defects liability is usually secured through retention money (typically five to ten percent of contract value held back until the defects liability period closes) or a bank letter of guarantee. Azerbaijani developers negotiating EPC or design-build contracts in Türkiye should confirm whether retention is cash-held, bonded, or convertible, and should specify the currency of the guarantee explicitly given lira volatility. A guarantee denominated in Turkish lira loses real value over a multi-year defects period unless indexed or replaced with a hard-currency instrument.
Practical Due Diligence Steps
Contract review : Before signing, have defects liability, retention, and dispute resolution clauses reviewed against both the Code of Obligations and any applicable FIDIC-style amendments, since Turkish courts will apply mandatory statutory protections regardless of contrary contract wording.
Inspection documentation : Request the full yapı denetim file, occupancy permit (iskan), and any structural certification before closing, particularly for projects completed within the last five years where structural liability windows remain open.
Dispute mechanism : Confirm whether disputes route to Turkish courts, arbitration under ICC or ISTAC rules, or another forum, and understand enforcement timelines if a claim becomes necessary.
Currency and guarantee terms : Where retention or performance bonds are involved, negotiate currency protection language upfront rather than after depreciation has already eroded the security's value.
The Bottom Line
Warranty and defects liability provisions are not a formality to be signed off quickly. For Azerbaijani investors building relationships with Turkish contractors and developers, particularly on larger commercial or residential projects, understanding the statutory floor set by the Code of Obligations, the parallel liability of building inspection firms, and the practical mechanics of retention and guarantees is essential to protecting capital well after the ribbon-cutting. Engaging local legal and technical advisory support during contract drafting, rather than only at the point of a dispute, remains the most reliable way to avoid costly surprises.
