How are disputes handled when a developer alters materials or layout from the signed presales specifications?

If a developer delivers an apartment that differs from the signed presales specifications, Turkish consumer law allows you to enforce conformity, demand correction, seek a price reduction, or rescind the contract, and provides procedural routes through Consumer Arbitration Committees and Consumer Courts, with mandatory mediation applying above certain thresholds. [1][2][3][4]

Legal Basis and Your Core Rights

Under Law No. 6502 on Consumer Protection, real estate bought for residential or holiday use is a consumer transaction, and the developer is obliged to deliver the property in conformity with the contract, project drawings, and the technical specification sheet (şartname). Deviations in materials, finishes, or layout constitute a lack of conformity (ayıplı ifa/ayıplı mal) that triggers consumer remedies. The primary remedies under Articles 11–12 include demanding repair or correction, replacement where applicable, a proportional price reduction, or rescission with a refund, provided legal conditions are met. For immovable property, the statutory responsibility period for defects is five years from delivery, extended in cases of concealed defects due to gross fault. [1][5]

If the purchase was an off‑plan or prepaid housing sale (ön ödemeli konut satışı), Article 40 of Law No. 6502 and the dedicated Regulation on Prepaid Housing Sales require delivery on the agreed date and in accordance with the contract and approved project. Consumers have a 14‑day withdrawal right without reason from the contract date, and an additional right to terminate before delivery under regulated conditions; where termination occurs after the withdrawal period but before delivery, the seller may charge limited compensation as set in the Regulation. These rules sit alongside the general defect remedies at delivery if the finished unit does not match agreed specifications. [2][3]

Contracts, Evidence, and Conformity to Specifications

Enforcement starts with what you signed. A preliminary real estate sale commitment (gayrimenkul satış vaadi sözleşmesi) must be executed in notarial form to be enforceable, and it should attach or reference the technical specifications, material lists, and layout plans. The Turkish Code of Obligations requires the official form for real estate sale commitments, and failing formality can limit contractual claims. The notarial deed and annexes, together with the building permit, project approvals, and marketing materials that form part of the contract, are the baseline for assessing deviations. Keeping dated brochures, signed specification sheets, and plan revisions is essential. [6]

When the delivered property diverges—such as replacing specified marble with ceramic, changing kitchen brand lines, or altering room dimensions—the buyer can first request specific performance: correction to conform to the agreed specification, where technically and legally possible. If correction is impossible or disproportionate, the buyer may seek a proportional price reduction reflecting the diminished value. Where nonconformity is substantial, rescission and refund may be sought. These remedies derive from Law No. 6502’s lack‑of‑conformity regime and, where relevant, the Code of Obligations’ performance and defect rules in sales and works contracts applied by courts to construction deliveries. [1][5][7]

How to Pursue a Claim and Where to File

For monetary claims within the annual threshold, consumers can apply to the provincial or district Consumer Arbitration Committee (Tüketici Hakem Heyeti). For 2024, the monetary limit for applications is 104,000 Turkish lira, and decisions are binding unless challenged in court within the statutory period. Above this threshold, or where non‑monetary relief such as specific performance is central, claims are brought before the specialized Consumer Courts (Tüketici Mahkemesi). Evidence typically includes the notarized preliminary sale deed, annexed specs, approved plans, delivery protocol, expert reports if available, and correspondence with the developer. [4][8]

As of 1 September 2023, mandatory mediation applies to consumer disputes filed in court, except where an application to the Consumer Arbitration Committee is required or chosen. This means that, before a Consumer Court hears your case, you must attempt mediation under the Law on Mediation in Civil Disputes. If mediation fails, the case proceeds to court. This step is designed to expedite settlements and reduce caseloads, and it is a procedural prerequisite in eligible disputes. [9][10]

Special Points for Off‑Plan and Prepaid Housing Sales

Prepaid housing sales have additional consumer protections. The developer must obtain a building permit before concluding prepaid housing contracts, must include mandatory content in the contract, and must deliver on time and as specified. Consumers may withdraw within 14 days without reason and without penalty. If the consumer terminates before delivery after this period, the seller may deduct a limited compensation amount and documented expenses permitted by the Regulation, but cannot impose arbitrary penalties. If, at delivery, the unit’s materials or layout do not match the signed specification, the standard defect remedies apply regardless of the earlier withdrawal/termination rights. These protections are enforceable before committees or courts as appropriate. [2][3]

Deadlines, Expert Evidence, and Practical Steps

Time limits matter. For immovable property under Law No. 6502, the defect liability period is five years from delivery. Bringing claims within this period preserves your remedies. Courts often rely on independent technical expert reports to establish the scope and value impact of deviations from the specification. Where possible, document discrepancies at delivery with a detailed handover report and dated photographs, and send a formal notice of defect and demand for remedy to the developer via notary or registered mail to evidence your request and start relevant periods. While Turkish law provides these pathways, outcomes depend on the contract text, the degree of deviation, and expert valuation; engaging a licensed attorney experienced in consumer and construction law is recommended for case‑specific strategy. [1][5][7]

Summary

Developers are legally obliged to deliver units that conform to the signed presales specifications and approved project. If materials or layouts are altered, Turkish consumer law allows you to demand correction, seek a price reduction, or rescind, with a five‑year responsibility period for immovable property defects from delivery. Enforcement routes include Consumer Arbitration Committees for claims up to the annually set monetary limit and Consumer Courts for higher‑value or non‑monetary claims, with mandatory mediation applying before court proceedings. Because disputes over construction conformity can be technical and time‑sensitive, consider obtaining professional legal advice tailored to your circumstances.
