What Are a Consumer's Rights If the Developer Fails to Deliver the Home on Time in Turkey? (2026)

What Does Late Delivery of a Home Mean in Legal Terms?

Failure to deliver the home on the agreed date means that the seller has not performed its obligation at all or not properly. Article 8(3) of Law No. 6502 expressly classifies the failure to deliver goods within the agreed period as non-conforming performance.

This provision allows a person who buys a home for non-commercial, non-professional purposes to rely on consumer law protection against the construction company. Such disputes are heard by the consumer courts.

The Court of Cassation applies this consumer law provision together with the default rules of the Turkish Code of Obligations:

Court of Cassation, 3rd Civil Chamber, 2026/173 E., 2026/3671 K., 09.06.2026

The Chamber held that late delivery under Article 8(3) of Law No. 6502 is a form of breach of contract under Article 112 et seq. of the Code of Obligations, and that the consumer may therefore use the optional rights in Article 125 of that Code because of the seller's default under Article 117.

If the contract fixes a specific delivery date, the seller falls into default when that date passes, without any need for a formal notice (Code of Obligations Art. 117/2). If delivery is tied to a vague term such as "on completion of construction", a notice must be served on the seller to put it in default.

The consumer's rights arise as soon as the delivery date passes; however, which right is used, in what order and with what notice directly determines the outcome.

Which Optional Rights Does the Consumer Have?

Against a seller in default, the consumer has three main options. The seller must first be given a reasonable additional period (Code of Obligations Art. 123); if delivery is still not made within that period, the consumer makes a choice (Art. 125):

• Demand delivery and delay compensation: The contract stays in force; in addition to transfer and delivery of the home, the loss caused by the delay, especially lost rent, is claimed.
• Waive delivery and claim expectation damages: The consumer gives up the home and claims the difference between the position they would have been in if the contract had been properly performed and their actual position.
• Withdraw from the contract: The consumer claims a refund of the price paid and compensation for the loss caused by the contract falling away.

No additional period is needed if the seller's conduct shows that it would be pointless, or if performance has become useless to the consumer because of the delay (Art. 124).

In a case examined by the Court of Cassation, a home due for delivery on 15.02.2020 was found to be about 60 percent complete at the time of the site inspection. The seller argued that the delay was caused by a fire on the building site and by the pandemic; nevertheless, the decision holding that the conditions for withdrawal were met and ordering a refund was upheld (Court of Cassation, 3rd Civil Chamber, 2026/173 E., 2026/3671 K.).

Once an optional right has been exercised, it generally cannot be reversed. A lawsuit seeking delivery and one based on withdrawal lead to different results in terms of both the claim and the evidence required.

What Special Rules Protect Consumers in Off-Plan Home Sales?

A pre-paid (off-plan) home sale is defined as a contract in which the consumer pays the price in advance, in cash or in instalments, and the seller undertakes to transfer or deliver the home after the price has been paid (Law No. 6502 Art. 40/1). Purchases of homes "from the ground up" or from a project usually fall into this category.

As a significant part of residential projects in Antalya is sold while still under construction, these rules frequently come up in disputes in the region, including those involving foreign buyers.

One important consequence follows from these rules: if the reason for withdrawal is the seller's failure to deliver, the seller cannot claim compensation from the consumer even within the first 24 months. This difference between withdrawal without reason and withdrawal based on the seller's default depends on how the withdrawal notice is worded.

If the home was bought with a bank loan, the loan is often a linked credit. In that case, if the home is not delivered at all or not properly and the consumer withdraws, the seller and the lending bank are jointly and severally liable for refunding the payments made (Law No. 6502 Art. 30/4). In the decision cited above, the Court of Cassation upheld holding the bank liable together with the seller, limited to the amount of the linked loan.

Can Lost Rent Be Claimed for the Delay Period?

Yes. The rent the consumer has lost for the period in which they would have lived in or let the home if it had been delivered on time is the most common head of delay compensation. Lost rent is calculated by an expert on the basis of the comparable market rent of the property from the delivery date until actual delivery. In places such as Antalya, where rents change markedly from one period to the next, calculating each period of the delay with its own comparables can significantly affect the amount of compensation.

Court of Cassation, 3rd Civil Chamber, 2025/5999 E., 2026/3677 K., 09.06.2026

Although the flat had been promised on a turnkey basis, the Chamber found that the property "had not been delivered on time and in the manner specified in the contract" and held the selling company liable both for the cost of missing and defective work and for rent compensation; it upheld the decision, correcting only the starting date of interest.

In the same decision, the claims directed at the construction company that had not signed the contract were dismissed for lack of standing. Who the lawsuit is filed against depends on who appears as the seller in the contract; the company that builds the project and the company that sells the home are not always the same.

If the contract provides for a penalty for delay, that amount is assessed separately. Whether the penalty can be claimed together with lost rent depends on the wording of the contract. The rights of a landowner against the contractor under a flat-for-land construction agreement are subject to different rules.

Does the Consumer's Position Change If the Contract Was Made in Simple Written Form?

A promise-to-sell contract for real estate is valid only if it is drawn up by a notary. In off-plan home sales, however, the legislator has given the consumer additional protection: if the form requirement has not been met, the seller cannot rely on the invalidity of the contract to the consumer's detriment (Law No. 6502 Art. 41/1).

Nevertheless, where a home was bought under a simple written contract, the legal basis for a claim for transfer of title and for a refund must be examined separately, because the courts assess such contracts under specific rules.

Missing or defective work that appears after delivery falls under defective performance and is subject to its own time limits.

Is Mediation Mandatory Before Filing a Lawsuit?

In disputes heard by consumer courts, applying to a mediator before filing a lawsuit is, as a rule, a precondition for the action (Law No. 6502 Art. 73/A). Claims for lost rent, delay compensation and refund of the price paid are subject to this rule.

The law contains an important exception: mediation is not a precondition in disputes that qualify as consumer transactions and arise from the real estate itself (Law No. 6502 Art. 73/A-1-d). A claim for registration of the home in the consumer's name at the land registry is of this nature.

If both registration and compensation are to be claimed in the same lawsuit, it must be determined from the outset which claims require mediation. Applications to consumer arbitration committees are limited to disputes below a monetary threshold that is reset each year (Law No. 6502 Art. 68); since home prices usually exceed this threshold, delivery disputes are generally heard by the consumer courts.

What Are the Common Mistakes When a Home Is Not Delivered?

A large share of the rights lost in late delivery cases results from wrong steps taken in the first months of the delay. The process consists of interlinked stages; a deficiency at one stage often cannot be cured at the next.

• Giving a withdrawal notice without reasons: A withdrawal not based on the seller's default may be treated as withdrawal without reason under Article 45 of Law No. 6502 and may allow the seller to claim compensation of up to eight percent of the price.
• Accepting a new delivery date in a signed document: An additional protocol or a "new delivery date" undertaking offered by the seller may contain a waiver of compensation rights for the earlier delay.
• Taking the keys without reservation: Accepting a late or incomplete home without any reservation and without a handover report makes it harder to prove later claims.
• Suing the wrong company: If the company that built the project and the seller that signed the contract are different, a lawsuit against the wrong party is dismissed for lack of standing; court costs and the other side's attorney fees are then borne by the consumer.
• Overlooking the linked loan: If the seller's ability to pay is weak, the bank's joint liability may be decisive for recovering the refund; failing to include the bank in the lawsuit leaves this safeguard unused.
• Signing a vague settlement in mediation: No lawsuit can be filed on matters agreed at the end of mediation. If the unresolved claims are not clearly carved out in the final report, items such as lost rent may be lost by the consumer's own signature.
