Contractor Delay in Turkey: Penalty Clauses, Rental Loss and Your Three Options under TBK 125

You bought off-plan in Istanbul. The contract said the keys would come in March. It is August, the lobby is still a concrete shell, and the developer's site manager keeps saying "two more months." You are paying rent somewhere else while an apartment you already financed sits unfinished.

Turkish law has a clear answer for this, but it is not the one most buyers expect. It does not begin with damages. It begins with a decision you have to make in a particular order, and one of the three options available to you extinguishes the other two the moment you exercise it. Buyers who complain for a year and then hire a lawyer often find the strongest remedy is gone — not because time ran out, but because of how they behaved in the meantime.

This guide sets out how a contractor is formally put in delay, what the three statutory options actually give you, how penalty clauses interact with real losses, and the practical order in which to move. Every provision cited here is from the current text of the relevant Turkish statute.

1. The developer is not "late" until you make it late

There is a gap between a missed deadline and legal default (temerrüt), and most of the leverage in these cases sits inside that gap.

Under Article 117 of the Turkish Code of Obligations (TBK), a debtor whose obligation has fallen due is placed in default by the creditor's notice. The second paragraph carves out the important exception: where the day of performance has been fixed jointly by the parties, or set by one of them through a proper notification under a right reserved in the contract, default occurs simply by that day passing.

So the question is what your contract says:

• A fixed calendar date ("handover no later than 31 March 2026") — the developer falls into default automatically when the date passes. You do not need to send anything.
• A vague or conditional date ("approximately 24 months from foundation permit", "subject to construction conditions") — the date is not fixed in the sense TBK 117 requires. You put the developer in default by serving a formal notice, in practice through a Turkish notary.

This distinction decides when your interest and your penalty start running. A buyer with a vague clause who sends the first notice in month fourteen has usually lost fourteen months of claim. The fix is cheap and immediate: send the notice now, through a notary, in Turkish, recording the delay and reserving all rights.

2. The extra step for reciprocal contracts: giving time

A property purchase is a reciprocal contract — you pay, they build and transfer. For those, TBK Article 123 adds a step: where one party is in default, the other may grant a reasonable period for performance, or ask the court to set one.

"Reasonable" is not defined by a number. It is measured against what remains to be done. Sixty days is arguable where the building is at occupancy-permit stage; it is not where the structure is unfinished.

Article 124 then lists three situations where no period need be given at all:

1. Where it is clear from the debtor's situation or conduct that granting time would be ineffective.
2. Where, as a result of the default, performance has become useless to the creditor.
3. Where it appears from the contract that performance will no longer be accepted if it does not occur at a specific time or within a specific period.

The first limb is the one that does real work in stalled-development cases. A developer with an abandoned site, unpaid subcontractors and no financing is not going to be rescued by another sixty days, and the law does not require you to pretend otherwise. But this is an evidential argument, not a slogan — it needs site photographs, the payment record, and correspondence.

3. The three options under TBK 125, and the trap inside them

This is the core of the article. Once the developer is in default and the period has expired (or was not required), Article 125 gives the buyer three routes.

Option one — performance plus delay damages. The first paragraph: where the debtor has not performed within the period given, or no period was required, the creditor is at all times entitled to demand performance of the obligation and compensation for the delay. You still get the apartment, and you are compensated for the waiting.

Option two — damages for non-performance. The second paragraph: the creditor may, by immediately notifying that they waive performance and delay damages, instead claim compensation for the loss arising from non-performance. You give up the flat and claim the loss instead.

Option three — rescission. Also under the second paragraph, the creditor may withdraw from the contract. The third paragraph then explains the consequence: the parties are released from their obligations to perform and may reclaim what they have already performed. Additionally, unless the debtor proves the absence of fault in falling into default, the creditor may also claim compensation for loss arising from the contract ceasing to have effect.

Two features of this structure catch buyers out.

The first is that options two and three require you to immediately declare that you are giving up performance. That is a real condition, not a formality. A buyer who spends six months demanding the keys and then pivots to rescission has a problem explaining the "immediately."

The second is that these are genuine alternatives. You cannot demand the apartment and claim non-performance damages for not getting it. In a rising market this choice is uncomfortable: a flat contracted at 2023 prices may now be worth considerably more than any damages award, which usually argues for option one — unless the developer is failing, in which case a judgment against an empty company is worth nothing and getting your money out matters more.

4. Penalty clauses: what the contract already gives you

Most Turkish off-plan contracts contain a penalty clause (cezai şart) — a pre-agreed sum per month of delay. Three provisions govern it, and together they explain why buyers both over-rely on and under-use these clauses.

You may usually claim the penalty and the property together. TBK Article 179 draws a distinction. Where a penalty is agreed for non-performance or defective performance generally, the creditor may demand either performance or the penalty. But where the penalty is agreed for failure to perform at the agreed time or place — which is exactly what a delay penalty is — the creditor may demand the penalty together with the principal obligation. There is a condition attached: this holds unless the creditor has expressly waived the right or accepted performance without reservation.

That last phrase deserves emphasis, because it is where buyers lose money. If you take the keys, sign the handover protocol and raise nothing, you may be treated as having accepted performance without reservation. Sign nothing at handover without a written reservation of your delay claim. One sentence added to the protocol preserves the claim.

The penalty is owed even with no loss. Article 180 states plainly that the agreed penalty must be paid even if the creditor suffered no loss whatsoever. You do not need rent receipts to claim the penalty. But the same article limits the upside: where your loss exceeds the penalty, you may claim the excess only by proving the debtor was at fault.

An excessive penalty gets cut — automatically. Article 182 lets the parties fix the amount freely, but its third paragraph provides that the judge reduces a penalty found excessive on the court's own motion. Nobody has to ask. So a claim resting entirely on an unusually large headline penalty is exposed, and the more durable position pairs a proportionate penalty with documented actual loss.

Article 182 also confirms that if the principal obligation is invalid, or becomes impossible for a reason the debtor is not answerable for, the penalty cannot be demanded.

5. Rental loss: proving what the delay actually cost

Delay damages under TBK 125 are not a fixed figure. For a residential buyer the usual measure is the rent you paid elsewhere, or the rent the unit would have produced, over the delay period.

What tends to persuade:

• Your own tenancy agreement and rent transfer records for the delay months.
• Comparable rental evidence for equivalent units in the same development or immediate area.
• The developer's own marketing material where it projected rental yield.
• An expert valuation, which the court will usually order in any event.

Where a penalty clause also exists, the interaction from Article 180 governs: the penalty is recoverable on its own terms, and the portion of your loss above it depends on proving fault. In practice a claim is usually pleaded as the penalty as the floor, with documented rental loss above it.

6. Protecting the asset while the case runs

A judgment is only worth what can be collected against it, and this is where delayed-development files are genuinely won or lost. A struggling developer may mortgage unsold units, transfer them to a related company, or let creditors register charges over the parcel.

Article 389 of the Code of Civil Procedure (HMK) provides the tool. An interim injunction (ihtiyati tedbir) may be granted where, because of a change in the current situation, obtaining the right would become significantly more difficult or entirely impossible, or where there is concern that a delay will cause an inconvenience or serious harm.

Applied to a delayed development, the change in the current situation is the unit being encumbered or transferred out of reach. An annotation on the Tapu (land registry) record for the unit you contracted for is the practical remedy: it does not give you ownership, but it warns off third parties and preserves the position until judgment.

Courts commonly require security for such a measure. That cost is real, and it should be weighed against the developer's financial condition — which is why the land registry record and the company's status are worth checking before deciding anything.

7. Which forum, and what you must do before filing

Whether you bought as a consumer or as a commercial party changes both the court and the pre-conditions.

For disputes heard in consumer courts, Article 73/A of the Consumer Protection Law No. 6502 — added in 2020 — makes applying to a mediator a condition of bringing the action. The provision carves out certain matters, including disputes within the remit of the consumer arbitration committee. Filing without completing mediation where it is required results in the claim being rejected on procedural grounds, so this is checked first, not last.

An individual buying a home for personal use is ordinarily a consumer. A company acquiring units for resale is generally not, which routes the dispute elsewhere and changes the applicable pre-conditions. Where a foreign buyer purchases through a Turkish company, the characterisation is not always obvious and is worth resolving before any filing.

On timing, TBK Article 146 provides that unless the law states otherwise, every claim is subject to a ten-year limitation period. Ten years is long. The real constraint is the developer's solvency, not the calendar.

8. A working order of steps

1. Read the handover clause first. Fixed date or conditional wording? This determines whether default has already occurred or whether you must trigger it.
2. Pull the land registry record for the unit and the parcel. Mortgages, annotations and transfers tell you how much time you actually have.
3. Serve a notarised notice. Record the delay, grant a reasonable period where appropriate, and reserve every right including the penalty.
4. Decide your TBK 125 route deliberately. Performance, non-performance damages, or rescission — informed by the market position and the developer's financial condition, not by frustration.
5. Assemble the loss file as you go. Tenancy agreement, rent transfers, comparable rents, correspondence, dated site photographs.
6. Apply for an interim injunction where the asset is at risk. Before the units are encumbered, not after.
7. Complete mediation where the consumer route applies. Confirm the forum before filing anything.
8. Reserve your claim in writing at handover. If the keys eventually arrive, do not sign a clean protocol.

Late handover is rarely a single decision. It is a sequence, and the sequence has an order. The buyers who recover most are usually not the ones with the strongest penalty clause — they are the ones who put the developer in default early, kept the option to demand performance open, and secured the unit on the land registry before anyone else did.
