Suing a Developer in the Turkish Consumer Courts: A Foreign Buyer's Guide

The court that hears a claim against a property developer in Türkiye is the consumer court (tüketici mahkemesi), provided the purchase was made for non-commercial and non-professional purposes — Article 73 of Consumer Protection Law No. 6502. Its door is not always the first one, though. A dispute worth less than TRY 186,000 — the figure for 2026 — must go first to the Consumer Arbitration Committee (Tüketici Hakem Heyeti); anything above that cannot be put to the committee at all and reaches the consumer court only after mediation, which Article 73/A makes a condition of suit — except where the dispute arises from the ayn of the immovable, such as a title cancellation and registration claim. Nationality plays no part in any of it: the definition of consumer in Article 3/1(k) carries no nationality or residence requirement.

That sequence is what most often catches a buyer based abroad: the substantive complaint may be perfectly clear, and the claim still fails at the threshold for want of the right forum or the mediation step. What follows takes the route in order — standing, forum, mediation, substantive basis, expert evidence, enforcement — as at July 2026.

Is a foreign buyer a “consumer” in Turkish law?

Three definitions in Article 3 of Law No. 6502 decide it. Consumer (paragraph k) means a natural or legal person acting for non-commercial and non-professional purposes — a test of purpose, not of status or nationality. Goods (paragraph h) expressly include “residential or holiday immovable property”, which is why the defective-goods regime in Articles 8 to 12 reaches a home at all. And consumer transaction (paragraph l) is drawn widely enough to cover works contracts (eser sözleşmeleri), so a contract with a builder does not escape the Law merely because it is characterised as construction rather than sale.

A buyer who acquired an apartment to live in or to holiday in therefore stands exactly where a local buyer stands. Buying through a company, or professionally with a view to resale, is what moves a purchaser out of the consumer regime and into the general law.

Arbitration committee or consumer court?

The dividing line is value, not subject matter. Article 68/1 makes an application to the provincial or district committee compulsory below TRY 186,000, the figure in force from 1 January to 31 December 2026 under the Communiqué on the raising of monetary limits published in the Official Gazette on 23 December 2025. Above it, the committee cannot hear the dispute at all. This is a hard division rather than a choice of route, and the figure is revalued annually — check the number in force on the day you file, not one published in an earlier year.

Three features of the court route matter to a claimant living abroad. Fees: Article 73/2 exempts consumer claimants from the charges under Fees Law No. 492 — the fees themselves, not expert advances, inspection costs or legal fees, which follow the general rules and the court’s costs order. Venue: Article 73/5 permits filing where the consumer resides, and where there is a foreign element Article 45 of Private International Law No. 5718 (MÖHUK) lets the consumer choose between the Turkish courts of their own domicile or habitual residence and those of the other party’s place of business, domicile or habitual residence — in practice, suing where the developer sits. Governing law: contracts marketed to foreign buyers often choose another law, but Article 26 preserves the minimum mandatory protection of the law of the consumer’s habitual residence.

By Article 73/4 the case runs under Part Six of Civil Procedure Law No. 6100 — the simplified procedure, in which pleadings are narrower and evidence is filed with the petition, so a file prepared before issue runs far better than one assembled as the case goes along.

Is mediation a condition of suit?

As a rule, yes: Article 73/A, added by Law No. 7251 in 2020, makes an application to a mediator a condition of suit (dava şartı). The exceptions are disputes within the committee’s remit, objections to committee decisions, collective actions under Article 73/6, actions under Article 74, and consumer disputes arising from the ayn of the immovable.

That last exception sorts claims rather than parties: a monetary claim — delay damages, a refund, a price reduction — goes through mediation, while a claim to have title registered in the buyer’s name does not. And since disputes below the threshold belong to the committee anyway, the condition bites on monetary claims above the threshold.

Mediation itself is short. Under Article 18/A of Mediation Law No. 6325 the mediator concludes the application within three weeks of appointment, extendable by one week at most, and between the application and the final minutes limitation is suspended and forfeiture periods do not run — worth knowing when a five-year period is closing. Two rules tilt the process toward the buyer. Article 73/A/2 disapplies the first-meeting attendance sanction against the consumer; since Law No. 7531 of 7 November 2024 that sanction means bearing half of the litigation costs the other side would otherwise carry, even where the absent party wins in whole or in part, and recovering only half the tariff attorney fee — a risk that lands on an absent developer. And Article 73/A/3 has the Ministry of Justice budget meet the consumer’s mediation fee in the situations it lists, capped at two hours’ worth.

What is the claim actually based on?

Late delivery. Article 44, as amended by Law No. 7392 of 24 March 2022, requires delivery within the contractual period and never more than 48 months from the contract date. Delivery is a legal event: registration of condominium title in the consumer’s name, or registration of construction servitude plus transfer of habitable possession. Article 45 permits no-cause rescission up to 24 months against statutory costs and graduated compensation, but Article 45/2 removes every deduction where the seller has not performed at all or not performed properly, and refunds fall due within 180 days of the notice reaching the seller. Code of Obligations No. 6098 supplies the default machinery (Articles 117 and 123 to 125). Watch Article 179/2: a delay penalty may be claimed alongside performance unless the creditor expressly waived it or accepted performance without reservation — taking the keys and signing a handover record without a written reservation can cost the claim — while Article 182/3 requires the judge to reduce an excessive penalty of their own motion. The detail is in our guide to late delivery of an off-plan apartment.

Defects. Article 8 treats a home as defective where it does not match the sample or model at delivery, lacks the qualities it objectively ought to have, or lacks features stated in advertising or on an internet portal. Defects appearing within six months of delivery are presumed to have existed then, the seller bearing the burden of proving otherwise (Article 10/1). Article 11 gives four elective remedies — rescission, price reduction, free repair, replacement — with repair or replacement in housing to be completed within 60 working days, damages available in addition (Article 11/6), and seller, producer and importer jointly liable. Limitation is five years from delivery (Article 12), and none at all where the defect was concealed by gross fault or fraud. Where the relationship is characterised as a works contract, Articles 474 to 478 apply instead — including a duty to inspect and notify within an appropriate period, and no rescission where removing works from the owner’s land would cause excessive harm. See our guide to construction defects and warranty periods.

What happens in the expert phase?

The bilirkişi stage is both the heart of a construction case and the main reason it takes time. Article 266 of Law No. 6100 lets the court, on application or of its own motion, take expert evidence where resolution requires special or technical knowledge outside the law — building defects, conformity with the approved project, repair costing. Equally, an expert may not be used where general knowledge or the legal knowledge the judicial office requires will do: characterising the contract, construing its terms and deciding the effect of a reservation on handover are questions for the judge. Since the amendment made by Law No. 6754, law graduates cannot serve as experts without documenting a separate specialisation.

Two consequences follow. The questions put to the expert largely decide the outcome, because a report answers only what it was asked. And an objection should rest on a technical deficiency or a wrong premise rather than disagreement with the conclusion, and be filed within the period the court sets, after which a supplementary or fresh report may be ordered. It is also why documenting the property early, before any repair by the developer, matters: the expert inspects what exists on the day of the site visit, not what existed when the defect appeared.

How long does it take, and can the judgment be collected?

No statutory deadline governs a consumer case as a whole; duration turns on the court’s docket and on how many rounds of expert evidence the file generates. The periods that can be planned around are the fixed ones: three weeks for mediation, extendable by one; 60 working days for repair or replacement; and 180 days for a refund after rescission.

Then comes the question usually asked last and best asked first: is the judgment collectable? It is enforced through the enforcement offices as an executory title under Enforcement and Bankruptcy Law No. 2004, but enforcement stops at the limits of what the debtor owns. Hence the practical weight of Article 42, which empowers the Ministry to fix the projects caught by unit count or project value: Article 12 of the implementing regulation sets that threshold at 30 or more housing units, and in those projects the seller must, before sales begin, take out building completion insurance or provide at least one of a bank letter of guarantee, the hakediş progress-payment system, or security through linked credit. Under Article 42/2, compensation and security within the scope of completion insurance cannot be included in the bankruptcy or liquidation estate, attached, or made subject to interim injunction or attachment. Under hakediş, buyers’ payments sit in a blocked account released only against actual construction progress, and a seller that fails to deliver loses its rights over the account. Which mechanism a project uses — or whether it has none, being under thirty units — is a question for before signature; where the developer itself has failed, see our guide to developer bankruptcy and konkordato.

A dispute with a Turkish developer is decided at two widely separated points: the forum and pre-action route at the beginning, and recovery at the end. Everything in between — the protective provisions of Law No. 6502, the default and penalty rules of the Code of Obligations — is open to a foreign buyer on the same terms as to a local one.
