Construction investment in Turkey can offer significant opportunities in residential development, commercial property, hotels, logistics facilities, industrial projects and mixed-use developments. However, construction investment carries legal risks that are fundamentally different from the risks involved in purchasing an already completed property.
When an investor enters a project before completion, the investor is not merely purchasing land or a future building.
The investor is effectively relying on a combination of:
land ownership, zoning rights, building permits, technical approvals, contractor capacity, project financing, contractual protection and the ability of the project ultimately to obtain lawful occupancy.
A failure in any one of these areas can materially affect the investment.
For this reason, construction due diligence in Turkey should not be limited to reviewing the title deed or examining the developer’s sales brochure.
A professional investigation should answer one central question:
Can this project legally, technically and financially reach completion in the form promised to the investor?
This article explains the principal legal checks that should be carried out before investing in a construction project in Turkey.
1. Start With the Land, Not the Building
Every construction project ultimately depends on the legal status of the land.
Before reviewing architectural drawings, projected sales prices or expected rental income, the investor should first verify:
- who owns the land;
- whether ownership is complete or shared;
- whether the developer owns the land;
- whether development is based on a construction-for-land-share arrangement;
- whether third parties have rights over the property;
- and whether the developer actually has sufficient authority to carry out the project.
The Turkish Civil Code makes the land registry the central public system for rights in immovable property. Article 1020 provides access to land registry information for persons demonstrating a legitimate interest, while registered real rights and encumbrances must be analysed before a project investment is completed.
The first rule of construction due diligence is therefore simple:
Never investigate the project without investigating the land beneath the project.
2. Obtain a Complete Title and Encumbrance Review
A title deed showing the developer as owner is only the beginning of the investigation.
The land may also contain:
- mortgages;
- attachments;
- injunctions;
- usufruct rights;
- easements;
- rights of residence;
- annotations concerning sale promises;
- construction-for-land-share agreements;
- urban transformation annotations;
- expropriation-related entries;
- or other restrictions.
TKGM’s Web Tapu infrastructure allows owners to access information concerning annotations, declarations and easements relating to their registered properties, demonstrating the importance of reviewing the complete encumbrance structure rather than relying only on the ownership line of the title deed.
For a construction investor, mortgages deserve particular attention.
A project site may be subject to substantial bank financing. That does not automatically make the project unsafe, but the investor must understand:
Who holds the mortgage?
What debt does it secure?
Can individual units be released from the mortgage?
At what stage will the bank provide a release?
What happens if the developer defaults?
A property advertised as a future apartment may ultimately remain within the enforcement risk of the developer’s project financing unless the contractual and banking structure has been carefully established.
3. Determine Whether the Developer Actually Owns the Land
Many projects are not constructed on land owned directly by the construction company marketing the development.
Common structures include:
- landowner–contractor construction agreements;
- revenue-sharing arrangements;
- construction-for-land-share agreements;
- development rights granted by power of attorney;
- joint ventures;
- and project companies established specifically for the development.
This creates an additional layer of legal risk.
The investor should establish:
- who owns the land;
- what legal relationship exists between the landowner and developer;
- whether the underlying development agreement is valid;
- whether the developer has authority to market or transfer the relevant unit;
- whether the agreement can be terminated;
- what would happen to purchasers if the landowner–developer relationship collapses.
A visually impressive construction site does not necessarily mean that the developer holds unrestricted ownership of the land.
4. Check the Zoning Status Before Valuing the Project
A construction project’s value is determined not only by the size of the land but by the legally permitted construction rights attached to it.
The investor should obtain and review:
- the current zoning status;
- the 1/5000 master development plan where relevant;
- the 1/1000 implementation zoning plan;
- zoning plan notes;
- building density;
- floor area ratio;
- maximum height;
- permitted use;
- building setbacks;
- road and public-service allocations;
- and special planning conditions.
A project marketed as “residential,” “hotel,” “commercial,” or “mixed-use” should be verified against the official planning documents.
This point is particularly important because Turkish zoning legislation continues to change. Most recently, amendments to the Planned Areas Zoning Regulation entered into force on 1 July 2026, including revisions concerning floor-area calculations, elevators, re-licensing and alterations to existing buildings.
Accordingly, feasibility studies prepared under older zoning rules should not automatically be relied upon for a current investment.
5. Do Not Assume the Current Zoning Plan Is Permanent
Zoning plans may be amended, cancelled or replaced.
An investor should therefore investigate not only the existing plan but also:
- pending plan amendments;
- recently suspended plans;
- objections;
- administrative litigation;
- superior-scale planning decisions;
- public infrastructure proposals;
- and potential changes to development density.
If the projected profitability of a development depends on a future zoning amendment, the investment carries a fundamentally different legal risk.
Statements such as:
“The municipality will increase the zoning.”
or
“This land will become commercial next year.”
should never be included in an investment valuation unless the legal planning process has actually reached the necessary stage.
Future zoning rights are expectations, not acquired property rights merely because a developer or broker predicts them.
6. Verify Whether the Parcel Is Properly Formed for Construction
A parcel may have favourable zoning but still be unsuitable for immediate construction.
Issues may include:
- incomplete parcelisation;
- Article 18 land-readjustment procedures;
- required merger of parcels;
- required subdivision;
- public-road dedication;
- unresolved cadastral problems;
- insufficient road frontage;
- or incompatibility between cadastral and zoning parcels.
An investor should therefore distinguish between:
land that appears developable on a zoning map
and
a legally formed parcel capable of receiving the contemplated building permit.
This distinction becomes especially important in large land-development projects.
7. The Building Permit Is One of the Most Important Documents
For a project already being marketed or constructed, the yapı ruhsatı — building permit must be reviewed.
A building permit should be examined together with:
- the approved architectural project;
- structural project;
- mechanical project;
- electrical project;
- soil and geological studies;
- fire requirements;
- and other statutory technical approvals.
The permit should correspond to the project actually being marketed.
If the sales brochure promises:
three towers, 450 apartments, commercial units and a swimming pool,
the investor should determine whether these features exist in the officially approved project — not merely in promotional material.
Under the Zoning Law framework, building permits and occupancy documents are issued through the competent administrative authorities, ordinarily municipalities or relevant special administrations depending on the location.
8. Check Whether the Building Permit Is Still Valid
A permit should not be accepted merely because a document labelled “building permit” exists.
The date and legal validity of the permit must be checked.
Under Article 29 of the Zoning Law, the ordinary framework requires construction to commence within two years from the permit date, and the structure must generally be completed within the statutory five-year permit period, subject to applicable renewal procedures.
This creates obvious due-diligence questions for stalled developments.
If construction stopped several years earlier, an investor should ask:
- Is the original licence still legally effective?
- Was it renewed?
- Has the approved project changed?
- Will new legislation apply upon re-licensing?
- Will restarting the project increase development costs?
An old construction site may therefore contain significant hidden regulatory costs.
9. Compare the Building Permit With the Actual Construction
Possession of a valid building permit does not guarantee that the construction actually follows the permit.
A physical inspection should compare:
approved project → building permit → actual construction.
Possible discrepancies include:
- additional floors;
- larger balconies;
- enclosed terraces;
- altered parking areas;
- converted technical areas;
- changed commercial units;
- relocated common areas;
- additional basement use;
- changes in gross or net areas;
- and unauthorised structural alterations.
Unauthorised construction may trigger administrative enforcement and prevent smooth occupancy approval.
Accordingly, legal due diligence should be coordinated with an architect or engineer.
10. Review the Approved Architectural Project, Not Only the Sales Brochure
Marketing material has commercial value, but the approved architectural project has far greater legal importance.
The investor should identify:
- the exact independent unit;
- floor;
- orientation;
- net and gross area;
- terrace;
- balcony;
- parking allocation;
- storage unit;
- common areas;
- technical areas;
- and permitted use.
This is particularly important in off-plan purchases.
A unit marketed as:
“150 m² apartment with private terrace and parking”
should be checked against the legally approved documentation.
Otherwise, the investor may discover after completion that a portion of the marketed property was actually a common area, technical space or unauthorised extension.
11. Examine the Contractor’s Legal Capacity
The construction company’s corporate existence should be investigated independently from the attractiveness of the project.
At minimum, the investor should verify:
- exact legal entity name;
- trade registry information;
- authorised representatives;
- shareholding structure;
- company history;
- capital;
- corporate purpose;
- prior projects;
- restructuring or insolvency indicators;
- and the identity of related project companies.
One of the most important technical regulatory checks is the contractor’s Yapı Müteahhidi Yetki Belge Numarası — Building Contractor Authorisation Number and classification.
The Ministry’s system records contractor authorisation and classification information electronically, and the relevant status can be investigated through the YAMBİS/Ministry system.
12. Contractor Classification Matters
Turkish law does not treat every contractor as automatically qualified for every size of project.
The regulatory system classifies building contractors according to specified qualification criteria and determines the level of construction activity they may undertake.
The Ministry applies group classifications extending through categories such as A, B, B1, C, C1, D, D1, E, E1, F, F1, G, G1 and H, depending on the applicable qualification structure.
Before investing, therefore, the investor should ask:
Does this contractor possess the proper authorisation and classification for this particular project?
The issue became even more relevant in 2026. The Regulation on Classification and Registration of Building Contractors was amended on 14 May 2026, including updated rules concerning recognition of certain private-sector work experience through 31 December 2026.
A developer’s commercial reputation should not substitute for regulatory verification.
13. Investigate the Contractor’s Real Track Record
A glossy list of completed developments is not enough.
The investor should investigate:
- whether the listed projects were actually completed by the same legal entity;
- whether occupancy permits were obtained;
- whether projects were delivered on time;
- whether serious defect litigation exists;
- whether previous developments contain zoning violations;
- and whether the company has repeatedly changed project entities.
The 2026 contractor rules themselves recognise officially documented private-sector experience, including completed projects with occupancy permits and substantial completion evidence, reinforcing the relevance of verified project history rather than marketing claims.
14. Construction Supervision Must Be Examined
Turkey has a statutory construction supervision framework under Law No. 4708 on Building Inspection.
The Ministry maintains a detailed regulatory system consisting of Law No. 4708, the Building Inspection Implementation Regulation and various technical communiqués concerning inspection bodies, laboratories, concrete sampling and electronic appointment mechanisms.
For an investment project, the investor should therefore identify:
- the building inspection company;
- whether its authorisation is valid;
- inspection history;
- laboratory results;
- concrete testing records;
- structural compliance;
- and whether inspection-related sanctions have occurred.
The purpose of the statutory system is to promote construction compatible with zoning, technical, health and safety standards.
15. Review Structural and Ground Investigation Documents
Turkey’s seismic environment makes geotechnical and structural review particularly important.
Legal due diligence should therefore coordinate with technical specialists to obtain and examine, where applicable:
- soil survey;
- geotechnical report;
- foundation design;
- structural calculations;
- concrete test records;
- reinforcement documentation;
- inspection reports;
- and design compliance.
A lawyer should not attempt to substitute legal review for structural engineering analysis.
The correct model is integrated due diligence:
lawyer + architect + civil engineer + surveyor where necessary.
16. Understand Who Is Contractually Responsible for Construction Defects
Where an investor directly engages a contractor, the relationship may fall within the rules governing a contract for work — eser sözleşmesi under the Turkish Code of Obligations.
Article 470 defines the structure as an agreement under which the contractor undertakes to create a work in return for payment.
Article 471 requires the contractor to perform with loyalty and care and refers to the professional and technical conduct expected from a prudent contractor in the same field.
The contractor may also be responsible for defective materials it supplies, and Article 472 imposes duties relating to material quality and warning the employer about circumstances that may threaten proper completion of the work.
This means that construction due diligence should not focus only on regulatory compliance.
The contract must also allocate responsibility for technical failure.
17. Delay Risk Must Be Contractually Controlled
Construction delay is one of the most common investment risks.
A well-drafted construction or investment agreement should clearly identify:
- commencement date;
- construction programme;
- milestones;
- completion date;
- delivery date;
- extension-of-time events;
- force majeure;
- employer-caused delay;
- contractor-caused delay;
- liquidated damages / penalty clauses;
- termination rights;
- and consequences of prolonged suspension.
The Turkish Code of Obligations provides important protection where the contractor fails to begin on time, delays the work contrary to the agreement or where it becomes clear that completion by the agreed date will not occur for reasons not attributable to the employer. Article 473 allows the employer, under its conditions, to withdraw without waiting until the contractual delivery date.
Consequently, investors should avoid contracts that contain a promised delivery date but no meaningful consequence for failure to achieve it.
18. Defective Work Should Be Addressed Before Completion
Article 473 also provides an important mechanism where it becomes apparent during construction that the work will be defective or contrary to contract because of the contractor’s fault.
The employer may provide an appropriate period for correction and warn that otherwise repair or continuation may be entrusted to a third party at the contractor’s risk and expense.
This principle is commercially important.
Investors should not wait until final delivery to document obvious defects.
Progress reports, photographs, technical notices and formal reservations should be maintained throughout construction.
19. Defect Liability Continues After Delivery
Completion does not necessarily end contractor exposure.
Under Article 478 of the Turkish Code of Obligations, claims arising from defective work are generally subject to:
- two years for works other than immovable structures;
- five years for immovable structures;
- and twenty years where the contractor is grossly at fault,
calculated from delivery under the statutory framework.
Construction contracts should therefore preserve documentary evidence concerning:
- completion;
- provisional acceptance;
- final acceptance;
- defects;
- repair obligations;
- warranties;
- and notification procedures.
20. Off-Plan Residential Investors Need a Separate Consumer-Law Review
Where an individual purchases a future residential unit for consumer purposes from a professional seller, the transaction may qualify as a prepaid housing sale under Law No. 6502.
This creates a highly regulated structure.
The legislation requires pre-contractual information and provides that a prepaid residential contract cannot be entered into before the relevant building permit has been obtained.
This is an extremely important due-diligence point.
If a developer is collecting money from consumers for a residential development before obtaining the legally required building permit, the transaction should immediately be examined for statutory compliance.
21. Check the Legal Form of the Off-Plan Contract
In prepaid consumer housing transactions, Article 41 of Law No. 6502 requires either:
- registration of the sale in the land registry; or
- execution of the promise-of-sale agreement in the legally required notarised form.
The legislation also prohibits the seller from requesting payment or instruments placing the consumer under debt before a valid contract has been established.
Therefore, an investor should be cautious if the developer asks for substantial payments based solely on:
- a reservation form;
- ordinary private agreement;
- sales brochure;
- payment schedule;
- or informal “pre-contract.”
22. Large Prepaid Housing Projects Require Completion Security
For qualifying prepaid housing projects, Turkish consumer legislation requires project completion security.
Article 42 of Law No. 6502 provides the legal basis for building completion insurance or alternative security mechanisms for projects exceeding the regulatory threshold.
According to the Ministry of Trade’s current 2026 consumer guidance, projects containing 30 or more residential units fall within the framework requiring building completion insurance or one of the legally permitted alternative security mechanisms before prepaid sales begin.
The investor should therefore request evidence of the actual security structure.
Do not simply ask:
“Is there a guarantee?”
Ask:
Who issued it?
What exactly does it secure?
What is the amount?
When can it be called?
Does it protect this particular purchaser?
23. Current Prepaid Housing Delivery Period: Check the Contract and the 48-Month Maximum
The legal rules governing prepaid housing delivery have changed over time.
Current Ministry of Trade guidance published in March 2026 states that the legal maximum delivery period for prepaid housing is 48 months from the contract date.
The contractual delivery date remains extremely important.
A developer should not treat the statutory maximum as an automatic right to delay every development for 48 months.
Investors should therefore separately identify:
the promised contractual delivery date
and
the outer statutory limit.
24. Review Payment Milestones Carefully
Construction investments often use staged payments.
Payment should ideally correspond to objectively verifiable project milestones.
Examples may include:
- land acquisition;
- permit issuance;
- foundation completion;
- structural completion;
- façade completion;
- mechanical completion;
- occupancy permit;
- and title transfer.
A dangerous structure requires the investor to pay most of the purchase price long before the project has achieved meaningful physical or legal progress.
The payment schedule should therefore be analysed together with the project’s actual construction status.
25. Avoid Paying the Wrong Company
Large developments may involve several companies with similar names:
Developer A.Ş.
Project Development Ltd.
Sales Company Ltd.
Construction A.Ş.
Landholding Company A.Ş.
The investor must determine precisely:
- who owns the land;
- who signed the contract;
- who received the money;
- who is responsible for construction;
- and who is obliged to transfer title.
Payments to a company that is not the contractual debtor may create serious recovery difficulties if the project later fails.
Every bank transfer should identify the relevant contract and project.
26. Analyse Project Finance and Insolvency Risk
A profitable project on paper can still fail because of inadequate financing.
Legal due diligence should therefore investigate, to the extent information is obtainable:
- project mortgages;
- bank financing;
- construction loans;
- developer guarantees;
- existing attachments;
- restructuring proceedings;
- significant creditor disputes;
- subcontractor exposure;
- and whether project cash flow depends entirely on future unit sales.
A construction project funded almost exclusively through advance purchaser payments presents a different risk profile from a project with committed institutional finance.
The investor should understand the project capital structure before committing substantial funds.
27. Require Contractual Security Where Commercially Possible
Depending on the nature and bargaining position of the parties, investors may consider mechanisms such as:
- bank guarantees;
- parent company guarantees;
- share pledges;
- mortgages;
- escrow arrangements;
- payment retention;
- performance bonds;
- completion guarantees;
- step-in rights;
- assignment of receivables;
- and staged release mechanisms.
The appropriate security package depends on the structure of the investment.
A contractual promise is only as valuable as the practical ability to enforce it.
28. Review the Developer’s Right to Modify the Project
Construction contracts frequently give developers broad authority to change:
- architectural plans;
- materials;
- landscaping;
- common areas;
- brands;
- facilities;
- unit layouts;
- and technical specifications.
Some flexibility is commercially unavoidable.
However, a clause stating that the developer may change the project “at its sole discretion” can materially undermine the investor’s expectations.
The contract should distinguish:
minor technically necessary modifications
from
material modifications affecting value, area, use or investment return.
29. Net and Gross Area Must Be Defined
One of the most common disputes in residential projects concerns advertised square metres.
Terms such as:
- gross area;
- saleable gross area;
- construction gross area;
- net usable area;
- common-area allocation;
may produce very different numbers.
The investor should therefore ensure that the contract identifies the exact measurement method.
A 160 m² marketed apartment may contain considerably less private usable interior space depending on how common areas are allocated.
A professional investment analysis should be based on the legally and contractually identifiable unit, not merely the largest number appearing in the brochure.
30. Check Parking, Storage and Common Facilities
Features such as:
- parking spaces;
- storage areas;
- gardens;
- terraces;
- swimming pools;
- sports areas;
- social facilities;
- reception areas;
- and roof spaces
should be legally categorised.
The investor should ask whether a particular area is:
part of the independent unit,
an appurtenance,
a common area,
or merely subject to an allocation or usage arrangement.
This distinction can materially affect resale value and future condominium disputes.
31. Verify Fire and Safety Compliance
Fire compliance has become even more important in the current regulatory environment.
A May 2026 legislative amendment introduced additional provisions concerning periodic fire-safety controls for certain buildings and created further duties within the building regulatory framework.
Construction due diligence should therefore include the project’s fire-safety documentation, particularly for:
- hotels;
- shopping centres;
- hospitals;
- high-rise buildings;
- large residential developments;
- industrial facilities;
- and other high-occupancy structures.
Fire compliance should not be postponed until the end of construction.
32. The Occupancy Permit Is the Real Finish Line
A construction project is not legally complete merely because the contractor announces:
“Construction finished.”
The project must reach the stage at which the required yapı kullanma izin belgesi — occupancy permit can be lawfully obtained.
The occupancy process demonstrates that the completed structure has passed through the applicable administrative completion framework.
The absence of an occupancy permit may affect:
- lawful use;
- financing;
- resale;
- utilities and operating licences in relevant contexts;
- commercial exploitation;
- and future due diligence.
Accordingly, investment contracts should avoid defining “completion” solely as physical completion.
Where appropriate, completion should include delivery of the legally required administrative documents.
33. Determine Who Is Responsible for Obtaining Occupancy
The contract should expressly allocate responsibility for:
- occupancy permit;
- condominium registration;
- title subdivision;
- technical acceptance;
- utility connections;
- fire approvals;
- operating licences where relevant;
- and other completion documentation.
Otherwise, the investor may receive the keys while important regulatory work remains unfinished.
For investment purposes:
“key delivery”
and
“legally complete project”
should not automatically be treated as the same event.
34. Check Whether the Project Is Within an Urban Transformation Regime
Projects involving demolition and reconstruction of existing buildings may fall within Law No. 6306 concerning transformation of areas under disaster risk.
Risk-bearing structures can be recorded in the land registry and become subject to specialised demolition and redevelopment procedures. Ministry guidance confirms that a risk-structure designation triggers formal notification and statutory procedures affecting the property.
If the project is based on urban transformation, the investor should examine:
- risk assessment;
- title annotations;
- owner decisions;
- developer agreement;
- demolition process;
- land shares;
- replacement-unit allocations;
- mortgages;
- and the applicable Law No. 6306 procedures.
Urban transformation projects should not be treated as ordinary greenfield construction investments.
35. Check for Special Land Regimes
Depending on location, additional approval regimes may apply.
Examples include:
- protected cultural assets;
- archaeological sites;
- coastal zones;
- agricultural land;
- forests;
- tourism zones;
- industrial zones;
- military/security restrictions;
- and environmentally sensitive areas.
Therefore, a building permit analysis alone may be insufficient for specialised developments.
The investor should determine whether additional public authorities have approval or supervision powers over the project.
36. Environmental Approval May Be Material for Large Projects
Certain large-scale developments may be affected by environmental legislation and permitting requirements.
Industrial facilities, tourism investments, infrastructure projects and certain major developments may require specific environmental assessments or approvals depending on project characteristics.
The legal due-diligence team should therefore identify early whether environmental approval is a condition precedent to lawful construction or operation.
Environmental compliance discovered late in a project can create significant delay and financing risk.
37. Foreign Investors Need an Additional Layer of Due Diligence
Foreign investors should conduct all of the above checks but must also consider:
- eligibility to acquire the property;
- military and security restrictions;
- acquisition limits;
- corporate acquisition structure;
- foreign investment regulations;
- tax structure;
- payment documentation;
- foreign-currency arrangements;
- and, where relevant, citizenship-by-investment restrictions.
A project being legally capable of construction does not automatically mean that a particular foreign investor can acquire the contemplated property in the intended structure.
Ownership eligibility and construction legality are separate questions.
38. Exit Rights Matter as Much as Entry Rights
Investors frequently focus on what happens if the project succeeds.
Due diligence should also ask:
What happens if it fails?
The contract should address circumstances such as:
- failure to obtain permits;
- construction suspension;
- prolonged delay;
- insolvency;
- material project modification;
- loss of title;
- cancellation of zoning rights;
- inability to obtain occupancy;
- refusal to transfer title;
- and serious construction defects.
The investor should know in advance whether the available remedy is:
specific performance, termination, refund, damages, penalty, security enforcement or another contractual remedy.
39. Dispute Resolution Should Be Designed Before the Dispute
The agreement should clearly determine:
- governing law;
- competent courts or arbitration;
- notice procedures;
- expert determination where appropriate;
- evidence standards;
- mediation requirements;
- and enforcement mechanisms.
International investors should pay particular attention to jurisdiction clauses and arbitration clauses.
A dispute clause drafted at the end of negotiations as boilerplate can become one of the most expensive clauses in the contract if the project fails.

Red Flags That Should Stop an Investor Before Payment
Certain circumstances justify heightened caution.
Examples include:
“The building permit will be issued soon.”
“The title is currently in another company but will be transferred later.”
“The bank mortgage will automatically disappear after completion.”
“The approved plans are different, but everyone builds this way.”
“The municipality verbally approved the extra floor.”
“You do not need to see the landowner agreement.”
“Pay now and we will sign the notarised agreement later.”
“The occupancy permit is only a formality.”
“The project can definitely be rezoned.”
“We use another company to receive the payments for accounting reasons.”
Any of these statements should trigger further investigation rather than immediate payment.
Conclusion: Construction Investment Is an Investment in Legal Completion
The greatest mistake in construction investment is to assess a project only by asking:
Is the location attractive?
Is the price below market?
Is the developer well known?
Those questions matter, but they are not sufficient.
A construction project’s true value depends on whether the developer can legally convert the land into the finished asset being promised.
That requires alignment between:
title, zoning, parcel, permit, approved project, contractor capacity, construction supervision, finance, contract and occupancy.
The Turkish regulatory environment is also dynamic. Amendments to the Planned Areas Zoning Regulation entered into force on 1 July 2026, while contractor classification rules were amended on 14 May 2026 and the broader construction regulatory framework was further modified through legislation enacted in May 2026.
For this reason, due diligence should always be based on the legislation and official records existing at the date of investment, not merely documents or legal opinions prepared when the development was initially conceived.
The practical rule for investors can be stated simply:
Do not invest in the project that has been marketed to you. Invest only after confirming the project that can legally be built, financed, completed, occupied and transferred to you.
In Turkish construction investment, legal due diligence is not an administrative formality performed before closing.
