What Should Foreign Buyers Do If a Developer Changes the Project After the Sale in Turkey? (2026 Updated Guide)

What can a foreign buyer do if a Turkish developer changes the property project after the sale? Learn about contract enforcement, misleading marketing, reduced facilities, smaller units, compensation, termination and litigation options.

Buying an apartment, villa or commercial unit from a development project in Turkey often means purchasing before construction has been completed. Foreign buyers may therefore rely heavily on the sale contract, architectural plans, technical specifications, brochures, model apartments, renderings and promises made by the developer. A serious dispute can arise when the developer later changes the project by reducing common areas, removing facilities, changing the building design, altering the apartment layout, substituting lower-quality materials or delivering a property materially different from what was originally sold. A developer does not necessarily have unlimited authority to change a project merely because construction is continuing. The buyer’s legal position depends on the sale documents, nature and significance of the modification, representations made before the transaction, approved project documents and circumstances of the particular purchase.

What Types of Project Changes Can Cause a Legal Dispute?

Disputes may arise when a developer changes the apartment layout, reduces usable space, changes the floor or location of the unit, removes a swimming pool or gym, reduces landscaped areas, changes parking arrangements, modifies the exterior design, eliminates promised social facilities, changes construction materials or significantly alters the overall concept of the development.

The first question is whether the change is minor or whether it materially affects what the buyer agreed to purchase.

The Sale Contract Should Be Reviewed First

The buyer should obtain every contractual document connected with the transaction. This can include the preliminary sale agreement, notarized documents where applicable, title records, payment schedule, annexes, technical specifications, architectural plans and handover documents.

The contract should then be examined for provisions concerning project modifications and the developer’s authority to make changes.

A Broad Modification Clause Does Not Necessarily End the Dispute

Some development contracts contain provisions allowing the developer to make technical or administrative changes.

However, the existence of such a clause should not automatically be interpreted as permission to transform the essential characteristics of the property without limitation.

The wording, purpose and extent of the clause should be examined together with the actual modification.

Compare What Was Sold With What Will Be Delivered

Create a detailed comparison between the property represented at the time of sale and the revised project.

The comparison should identify changes concerning square meters, room configuration, balconies, terraces, views, parking, common facilities, landscaping, building quality and other characteristics that influenced the purchase.

Preserve the Original Architectural Plans

The plans shown to the buyer when the contract was signed can become important evidence.

Foreign buyers should preserve original PDF files, printed plans, emails and other documents showing the unit configuration represented during negotiations.

Marketing Materials Can Become Relevant Evidence

Brochures, advertisements, project websites, videos, renderings and sales presentations may help establish how the development was marketed.

A developer may argue that marketing images were illustrative. The legal significance of each representation therefore depends on the circumstances and contractual documents.

Save Digital Advertising Before It Changes

Online project pages can be modified after construction problems arise.

Buyers should preserve relevant screenshots, electronic communications and promotional materials as soon as they become aware of a substantial project change.

WhatsApp and Email Communications May Be Important

Foreign buyers often negotiate Turkish property purchases remotely. Important representations may therefore appear in emails or messaging applications.

Messages concerning apartment size, view, facilities, completion date, materials or guaranteed features should be preserved in their original context.

What If the Apartment Becomes Smaller?

A reduction in the size of the purchased unit can be commercially significant.

The buyer should determine precisely which measurement has changed and whether the dispute concerns gross area, net usable area, common-area allocation or another measurement concept.

An independent technical measurement may be necessary.

Net and Gross Square Meters Should Not Be Confused

Foreign buyers frequently encounter disputes because marketing materials emphasize gross area while the buyer expects the figure to represent usable interior space.

The contract, approved plans and technical measurements should be compared before calculating any alleged deficiency.

What If the Developer Changes the Apartment Layout?

Moving walls, eliminating a room, reducing a balcony or materially changing the internal configuration may affect the buyer’s intended use and the property’s market value.

The developer should be asked to identify the contractual and technical basis for the modification.

What If the View Changes?

A sea, city, forest or landscape view can materially influence the purchase price.

If the developer changes building placement, constructs another block or otherwise alters a specifically represented view, the buyer should preserve evidence demonstrating what was promised and how the modification affects the property.

Removal of Social Facilities Can Be Significant

Foreign buyers are frequently attracted to developments advertising swimming pools, gyms, children’s areas, gardens, security services, sports facilities and other amenities.

If important facilities disappear after the sale, the buyer should examine whether they formed part of the contractual project or merely preliminary promotional concepts.

Parking Changes Can Affect Property Value

Changing private parking into shared parking, reducing spaces or relocating parking facilities may create disputes.

The buyer should compare the contractual documents and approved project information with the revised arrangement.

Lower-Quality Materials Can Create a Separate Claim

Project changes are not limited to architecture.

A developer may replace flooring, windows, kitchen systems, bathroom fixtures, heating equipment, façade materials or other promised products with lower-quality alternatives.

The technical specification becomes particularly important in these cases.

Obtain the Technical Specification

A professionally drafted sale normally includes or refers to specifications identifying construction standards and materials.

Compare those specifications with the products actually installed.

Independent Expert Examination Can Be Critical

An architect, civil engineer, surveyor or other appropriate technical expert can document differences between the promised project and actual construction.

Technical evidence is particularly important where the developer argues that the changes are equivalent or insignificant.

Check the Approved Project at the Municipality

The buyer should determine whether the developer’s revised construction corresponds with the legally approved architectural project and applicable permits.

A contractual dispute and a zoning or permit problem can exist simultaneously, but they should be analyzed separately.

An Approved Modification Does Not Automatically Resolve the Contractual Issue

A developer may argue that a revised project has received administrative approval.

Even if the modification is valid from a planning perspective, a separate question can remain as to whether changing the property breaches contractual obligations owed to the buyer.

Can the Buyer Demand Completion According to the Original Agreement?

Potentially, depending on the contractual obligation, construction status and whether performance remains legally and technically possible.

Specific performance should be evaluated against alternative remedies such as price reduction, damages or termination.

Can the Buyer Demand a Price Reduction?

Potentially. Where the delivered property is worth less because of a material difference, a price-reduction claim may become relevant depending on the legal characterization of the dispute.

An expert valuation may be needed to quantify the economic effect.

Can the Buyer Terminate the Contract?

A sufficiently serious breach may potentially support termination or another remedy, depending on the contract and applicable law.

Not every minor modification will necessarily justify cancellation of the entire transaction.

The materiality of the breach is therefore important.

Can the Buyer Recover Payments Already Made?

If the transaction is lawfully terminated or otherwise unwound, recovery of amounts paid may become an important part of the claim.

Bank transfers, receipts and payment schedules should be preserved.

Additional Damages May Need Separate Proof

A buyer may also claim that the developer’s breach caused additional financial losses.

Such claims require careful analysis of causation, foreseeability, contractual allocation and proof of the actual loss.

Property Value Loss Should Be Documented

If the buyer keeps the property but alleges that the project modification reduced its market value, an independent valuation can be particularly useful.

The comparison should focus on the value of the property promised and the value of the property actually delivered.

What If the Developer Offers Another Apartment?

Developers sometimes propose exchanging the affected unit for another property.

Before accepting, the buyer should compare location, floor, orientation, square meters, title status, value, completion status and any additional payment demanded.

Any replacement arrangement should be documented formally.

Do Not Surrender Existing Rights Accidentally

Settlement documents may contain releases or waivers.

A foreign buyer should understand whether accepting a replacement unit, discount or additional facility will waive existing claims.

Title Deed Transfer Does Not Necessarily Resolve Every Defect Dispute

Receiving title does not automatically mean that every contractual disagreement concerning construction, quality or delivery disappears.

The specific documents signed during transfer and handover should nevertheless be reviewed carefully.

Be Careful With Handover Forms

A developer may request a document stating that the property was received without reservation.

Before signing, the buyer should record visible deficiencies and significant project differences.

Record Objections in Writing

If the buyer discovers a material change, written notice can help establish that the modification was not accepted silently.

The notice should identify the original promise, actual change and remedy requested.

Do Not Rely Only on Conversations With the Sales Office

Sales representatives may promise that a facility will later be restored or that compensation will be offered.

Important proposals should be confirmed in writing.

Foreign Buyers Should Verify the Developer Company

Identify the legal entity that signed the contract and determine whether the landowner, developer, contractor and sales company are the same entity.

Complex project structures can affect which company should be pursued.

Check the Title Deed and Land Ownership

The company marketing the project may not necessarily own the land.

Title records should therefore be examined to determine ownership, mortgages, annotations and other restrictions relevant to enforcement.

Mortgages and Attachments Can Affect Strategy

If the developer is experiencing financial difficulty, waiting indefinitely for voluntary correction can increase risk.

The buyer should determine whether the property or development land is subject to mortgages, attachments or other encumbrances.

Interim Measures May Become Important

Where there is a serious risk that property will be transferred or assets will disappear during litigation, available protective measures should be evaluated promptly.

The requirements depend on the particular claim and evidence.

Multiple Buyers May Have the Same Problem

A project-wide modification may affect dozens or hundreds of purchasers.

Foreign buyers should determine whether the issue is unique to their unit or reflects a broader alteration affecting the entire development.

Each Buyer’s Contract Still Matters

Even where many buyers are affected, individual contracts, payment histories and representations can differ.

A project-wide problem should therefore not eliminate buyer-specific legal analysis.

Citizenship-by-Investment Purchases Require Additional Attention

If the property was purchased as part of a Turkish citizenship investment, termination, replacement or restructuring of the transaction may have immigration and investment consequences.

The real-estate remedy should therefore be coordinated with the applicable citizenship requirements before significant changes are made.

Do Not Sign a Replacement Agreement Without Reviewing Its Effect

Replacing one property with another can alter transaction values, title arrangements and other conditions relevant to the original investment structure.

This should be reviewed before execution.

Foreign Currency Payments Should Be Documented

Where the buyer paid in euros, dollars, pounds or another currency, preserve bank records showing the transaction history.

Currency movements can complicate the financial consequences of cancellation or damages.

Power of Attorney Transactions Should Be Reviewed

If the purchase was completed through an attorney-in-fact, obtain the power of attorney and transaction records.

Confirm precisely what was signed on the buyer’s behalf.

Limitation and Procedural Periods Should Not Be Ignored

The applicable periods depend on the legal basis of the claim and transaction structure.

Foreign buyers should therefore avoid waiting for years based solely on repeated assurances that the developer will eventually correct the project.

Evidence Should Be Collected Before Litigation

A strong file can include the sale contract, annexes, technical specification, original and revised plans, title records, advertisements, correspondence, payment evidence, photographs, expert reports and municipality records.

The evidence should demonstrate the difference between what was promised and what was actually delivered.

What If the Developer Claims the Buyer Consented?

Review whether the buyer signed any amendment, revised plan, handover document or waiver.

Consent should not simply be inferred from the developer’s internal records without examining what the buyer actually accepted.

What If the Buyer Lives Abroad?

A foreign buyer does not necessarily need to remain physically in Turkey throughout the dispute.

Depending on the procedure, representation through a properly authorized lawyer may allow many steps to be handled without repeated travel.

Negotiation Can Still Be Effective

Litigation is not always the first commercially optimal solution.

Where the developer remains financially stable, negotiations may produce restoration of promised features, a replacement property, price reduction or compensation.

Any settlement should be documented precisely.

When Should Litigation Be Considered?

Litigation becomes particularly important where the developer denies the original promise, refuses meaningful correction, attempts to impose a materially inferior property or places the buyer’s investment at risk.

The correct type of action depends on the transaction and remedy sought.

2026 Practical Checklist for Foreign Buyers

Foreign buyers discovering a project change should immediately preserve the original advertisement and plans, obtain the complete contract and technical specification, compare the revised project, photograph construction, obtain title and project records, save communications, commission technical or valuation evidence where necessary, send an appropriate written objection and evaluate performance, price reduction, compensation, termination and protective remedies before signing any new document.

Frequently Asked Questions

Can a Turkish developer change a project after selling an apartment?

Some technical changes may be possible depending on the contract and applicable rules, but this does not mean a developer has unlimited authority to make material changes affecting what the buyer purchased.

Can a foreign buyer cancel the purchase because the project changed?

Potentially, where the change constitutes a sufficiently serious breach and the applicable legal requirements are satisfied. The contract and extent of the modification must be examined.

What if the apartment is smaller than advertised?

The contractual and approved measurements should be compared with the completed unit. An independent technical measurement and valuation may be necessary.

Can the buyer claim compensation if facilities are removed?

Potentially. The buyer must establish the relevant contractual or legally enforceable representation, breach and resulting loss.

Are brochures and advertisements legally relevant?

They can be relevant evidence depending on the circumstances, particularly when they help establish representations made during the sale.

What if the developer has municipal approval for the change?

Administrative approval does not necessarily determine whether the developer has complied with its separate contractual obligations to the buyer.

Should the buyer sign the handover form?

The document should be reviewed carefully. Material defects or differences should not be ignored when acknowledging delivery.

Can a foreign buyer pursue the case from abroad?

In many situations, legal representation can allow substantial parts of the process to be handled without the buyer continuously remaining in Turkey.

What if the property was purchased for Turkish citizenship?

Any termination, replacement or restructuring should be reviewed for its potential effect on the investment conditions before action is taken.

What should the buyer do first?

Preserve evidence of the project originally sold and compare it systematically with the revised or delivered property. The strength of the claim will often depend on proving precisely what the developer promised, what was changed and how materially that change affected the buyer’s property and investment.
