Buying property in Turkey? This 2026 legal due diligence guide explains how foreign buyers can verify title deeds, ownership, mortgages, liens, attachments, zoning, construction permits, occupancy status, seller authority, debts, contracts and payment risks before purchasing Turkish real estate.

Buying property in Turkey should never begin with the purchase agreement. It should begin with legal due diligence.

For a foreign purchaser, the greatest risks are often invisible during a property viewing. An apartment may look perfect while being subject to a mortgage. A villa may have unauthorized extensions. A seller may be negotiating through a representative whose power of attorney is insufficient. A newly constructed apartment may be located in a development with unresolved legal or construction issues. A property advertised as suitable for a particular investment purpose may not actually satisfy the relevant legal requirements.

Official investment guidance specifically advises purchasers to check mortgages, liens and similar restrictions before beginning the title-transfer process. It also emphasizes an essential point: ownership of Turkish real estate is acquired through registration at the land registry; merely signing a preliminary agreement does not itself transfer ownership. (Invest.gov.tr)

For this reason, legal due diligence should answer one fundamental question before the purchaser transfers substantial funds:

Are you legally receiving exactly what you believe you are buying, free from risks you have not agreed to accept?

What Is Property Legal Due Diligence in Turkey?

Legal due diligence is a systematic investigation conducted before a property acquisition to identify legal defects, restrictions, liabilities and transaction risks.

It should not be confused with a property valuation or physical inspection. A valuation asks what the property may be worth. A technical inspection considers its physical condition. Legal due diligence examines whether the property can be safely acquired and whether the purchaser will obtain the legal rights expected from the transaction.

A comprehensive investigation should normally cover the purchaser, seller, title record, property, building, development, contracts, encumbrances, payment structure and intended use of the property.

For higher-value investments, these issues should be examined together rather than independently.

1. Verify Whether the Foreign Buyer Is Eligible to Acquire the Property

The first investigation should concern the purchaser.

Foreign property ownership in Turkey is subject to statutory restrictions. Foreign natural persons who satisfy the applicable nationality requirements can acquire qualifying real estate, but restrictions remain concerning total acquisition area, certain locations and other circumstances.

Current official guidance states that foreign natural persons may generally acquire up to 30 hectares nationwide, while aggregate foreign natural-person ownership cannot exceed 10% of the privately owned area within the relevant district. Certain military and security-related locations are also restricted. (Invest.gov.tr)

Therefore, the first question should not simply be:

“Can foreigners buy property in Turkey?”

It should be:

“Can this particular foreign purchaser legally acquire this particular property?”

2. Identify the Exact Property

Never conduct due diligence using only an advertisement address.

The property should be identified according to its official registration information. For apartments, the investigation should establish precisely which independent unit is being purchased.

This is particularly important in large residential developments where dozens of apartments may have nearly identical layouts.

The purchaser should compare the property physically shown by the agent with the property identified in the legal documentation.

3. Verify the Registered Owner

One of the most basic questions is also one of the most important:

Who actually owns the property?

Do not rely solely on the seller, developer or real estate agency.

Official investment guidance notes that basic parcel information can be investigated through the land registry’s parcel inquiry infrastructure, although ownership information is not publicly displayed through that basic service. (Invest.gov.tr)

For transaction due diligence, the current registered ownership position should therefore be independently established.

4. Compare the Seller With the Registered Owner

The person negotiating the transaction may not be the registered owner.

This can occur where the seller acts through a relative, real estate agent, company representative or attorney.

Before paying a substantial deposit, establish the legal relationship between the person demanding payment and the registered owner.

If that relationship cannot be explained and documented, the transaction should not proceed merely because the property appears attractive.

5. Verify the Seller’s Identity

The seller’s identity should correspond with the ownership information.

Identity verification is especially important in remote transactions where the purchaser has never met the seller personally.

Fraud involving copied identity documents, impersonation and unauthorized representatives can create serious risks for international purchasers.

6. Examine Powers of Attorney Carefully

A seller may legitimately conduct the transaction through a representative.

However, the existence of a power of attorney does not automatically mean that the representative has unlimited authority.

The document should be examined for its authenticity, current validity and scope. The representative must possess sufficient authority for the intended transaction.

Particular attention should be paid where the representative claims authority not only to sell but also to receive the purchase price.

Those are separate issues that should not simply be assumed.

7. Verify Corporate Sellers

If the property belongs to a company, the due diligence becomes broader.

The purchaser should verify the company’s existence and the authority of the person signing on its behalf.

Depending on the transaction, relevant corporate records, representation authority and internal approvals may need to be examined.

A salesperson working for a developer should not automatically be assumed to have authority to bind the company to every contractual commitment.

8. Obtain and Review the Current Title Record

This is the core of property due diligence.

A photocopy or photograph of a title document supplied by the seller is not sufficient.

Even a genuine document may be outdated.

Since the document was issued, the property may have been mortgaged, attached, transferred or subjected to another registered restriction.

The relevant question is therefore not:

“Is this title document genuine?”

It is:

“What does the current title record show today?”

9. Check for Mortgages

A mortgage is one of the most important encumbrances to investigate.

Official guidance for foreign purchasers specifically recommends checking mortgages and similar restrictions before beginning the acquisition procedure. (Invest.gov.tr)

A mortgaged property can potentially be purchased, but the mortgage must be understood and appropriately handled.

The purchaser should determine who holds the mortgage, what obligation it secures, whether the underlying debt remains outstanding and how the mortgage will be discharged.

10. Never Rely on “The Mortgage Will Be Removed Later”

This statement should not replace a proper closing mechanism.

If the seller intends to use part of the purchase price to discharge the mortgage, payment and release should be coordinated carefully.

The purchaser should avoid transferring the entire purchase price and simply trusting that the seller will remove the mortgage afterward.

11. Check for Attachments

An attachment may indicate creditor enforcement against the owner.

This can create significant acquisition risk.

The purchaser should identify relevant attachments and determine whether they can and will be removed before or during closing.

If the seller has significant financial problems, broader investigation may also be appropriate.

12. Check Other Registered Restrictions

A complete title review should not stop at mortgages and attachments.

Depending on the property, registered rights and restrictions may include matters affecting use, access, occupation, transfer or economic value.

Each relevant entry should be legally interpreted.

Foreign buyers should not accept a salesperson’s explanation that an unfamiliar title entry is “standard” without independent review.

13. Investigate Easements

An easement can affect how the property is used.

Examples can involve access, infrastructure or other rights benefiting another property or person.

Some easements are commercially insignificant. Others can materially affect development plans or privacy.

The significance depends on the property.

14. Check Usufruct and Similar Rights

Registered rights held by another person can substantially limit what the new owner can actually do with the property.

The purchaser should therefore understand whether another individual possesses a right that may continue after ownership changes.

Buying legal title is not necessarily equivalent to obtaining immediate unrestricted possession and use.

15. Confirm the Property’s Legal Classification

A buyer should understand exactly what is registered.

The marketing description and legal classification may not always correspond.

A unit marketed as a luxury residence, for example, should be checked against its actual legal status.

Likewise, land advertised as suitable for immediate development may have a legal or planning status that produces a very different investment outcome.

16. Compare Registered Area With the Property Being Sold

Property advertisements frequently emphasize square meters.

But different measurements may be used in marketing materials.

Foreign buyers should understand what area is actually registered and what portion represents usable interior space, gross construction area, common-area allocation or other measurements.

A discrepancy does not automatically establish fraud, but significant differences require explanation before purchase.

17. Investigate Zoning and Planning Status

Title ownership does not automatically prove that a property can be used or developed in the manner intended by the buyer.

This is particularly important for:

land, villas, commercial property, hotels, industrial assets and redevelopment projects.

Planning status should be examined where it is material to the investment.

An investor buying land because an agent promises that apartments can be constructed should independently establish whether the applicable planning framework actually supports that assumption.

18. Never Buy Land Based Solely on Future Zoning Promises

Statements such as:

“The land will become residential next year” or “A new development plan is guaranteed”

should not be incorporated into the purchase valuation unless there is a legally reliable basis.

Future administrative decisions are not guaranteed merely because an intermediary expects them.

The investor should value the property according to its current legal position while separately evaluating potential future development.

19. Check the Building Permit

For buildings, the relevant construction authorization should be investigated where appropriate.

The buyer should determine whether the structure was legally authorized and whether the property corresponds with the approved project.

This becomes particularly important for villas, newly built properties and buildings that have undergone substantial alterations.

20. Compare the Actual Building With the Approved Project

A legally permitted building can later be modified unlawfully.

Potential unauthorized additions can include enclosed balconies, additional rooms, roof structures, extensions or changes to common areas.

A physical inspection should therefore be coordinated with documentary due diligence where material alterations are suspected.

21. Check Occupancy Status

For completed developments, the legal status of completion and occupancy should be investigated.

This can affect financing, utilities, insurance, resale and the overall legal quality of the investment.

A newly constructed building should not automatically be treated as fully compliant merely because people already live there.

22. Distinguish Between Condominium Ownership and Construction Easement Structures

Apartment purchasers should understand the registration structure applicable to the independent unit.

A completed apartment with established condominium ownership can present a different legal position from an apartment connected with an unfinished development.

This distinction can become particularly important in off-plan or recently completed projects.

23. Examine the Building Management Plan

Apartment ownership also means participation in a collective property structure.

The management plan may regulate important issues concerning the building or development.

A purchaser should understand relevant rules before acquiring a high-value unit, particularly where the intended use differs from ordinary residential occupation.

24. Check Common Expenses

Luxury residential developments can have substantial monthly management charges.

Foreign investors should obtain information concerning current common expenses and, where relevant, outstanding liabilities associated with the unit.

A relatively inexpensive purchase can become an expensive investment if annual management and maintenance costs are unexpectedly high.

25. Review the Property’s Earthquake Insurance Position

Compulsory earthquake insurance is an important element of Turkish residential property ownership.

Official DASK guidance confirms that qualifying residential buildings and independent units are subject to compulsory earthquake insurance. Its validity is checked in relevant title deed transactions involving properties within the insurance regime. (DASK)

The purchaser should therefore review the applicable insurance position as part of closing preparation.

26. Do Not Confuse Compulsory Earthquake Insurance With Full Property Insurance

This distinction matters.

DASK coverage concerns specified direct physical losses caused by earthquakes and certain earthquake-related events within the applicable policy limits. (DASK)

It should not automatically be treated as comprehensive protection against every property risk.

Foreign purchasers should separately consider whether additional property insurance is appropriate.

27. Investigate Structural and Earthquake Risk

Insurance does not prove structural safety.

For older buildings or high-value acquisitions, purchasers should consider technical due diligence concerning the building’s structural condition.

Legal and technical investigations serve different purposes.

A lawyer may identify legal irregularities in construction documentation, while an engineer evaluates physical and structural conditions.

Both can be important.

28. Review Previous Damage Where Relevant

Where a building has experienced earthquake, fire, flooding or major structural damage, additional investigation may be appropriate.

The buyer should understand whether repairs were performed properly and whether the building’s legal and technical documentation reflects its current condition.

29. Conduct Enhanced Due Diligence for Newly Built Properties

Buying from a construction company requires broader investigation than simply checking the apartment.

The purchaser should examine the developer, underlying land, development rights, construction authorization, project structure, mortgages, unit identification, payment arrangements and delivery obligations.

A beautiful sales office does not establish legal security.

30. Verify That the Developer Controls the Relevant Property

The developer marketing the project may not necessarily own the underlying land outright.

The project may involve a contractual arrangement with a landowner.

Foreign purchasers should therefore understand the legal basis on which the developer is offering the apartment for sale.

31. Check Project-Level Mortgages

Construction projects are frequently financed through borrowing.

A mortgage over the development land can potentially affect individual units depending on the transaction structure.

The buyer should therefore investigate whether financing security exists and how the specific purchased unit will be released.

32. Do Not Rely Solely on the Developer’s Standard Contract

Developer contracts are normally prepared primarily to protect the developer.

The purchaser should review provisions concerning price, payment, delivery, delay, project modifications, cancellation, refund rights, title transfer, mortgage release, defects and contractual penalties.

Marketing promises should also be incorporated into legally enforceable documentation where they are material to the purchase decision.

33. Conduct Enhanced Due Diligence for Off-Plan Property

Off-plan purchases involve a different category of risk because the buyer may be paying for an asset that is not yet completed.

The legal review should examine what happens if construction is delayed, significantly modified or never completed.

The contract should also identify the precise unit and establish the circumstances in which ownership will ultimately be transferred.

34. Investigate Construction Progress

A purchaser paying installments over a long construction period should not rely solely on promotional photographs or sales updates.

Where appropriate, construction progress should be independently monitored.

Payment milestones should correspond with a transaction structure that adequately protects the buyer.

35. Verify the Real Estate Agency

Due diligence should also extend to the intermediary.

Turkey operates an Electronic Advertisement Verification System designed to verify identity and authorization connected with electronic real estate advertisements. (Elektronik İlan Doğrulama Sistemi)

However, advertisement verification does not replace legal due diligence on the property itself.

A legitimate agency can still market a legally problematic property.

36. Do Not Treat the Agent as the Buyer’s Independent Adviser

A real estate agent generally has a commercial interest in completion of the sale.

That does not make the agent dishonest, but it does create a different role from independent legal representation.

The person earning commission from the sale should not be the purchaser’s sole source of information concerning title defects, seller authority, contractual risks and payment security.

37. Review the Reservation Agreement Before Paying a Deposit

Foreign buyers frequently lose negotiating leverage at this stage.

A salesperson may request a relatively small reservation payment before providing complete property documentation.

Before paying, establish what happens if due diligence later reveals:

a mortgage, attachment, ownership defect, construction problem or another material legal issue.

Refund rights should be clearly documented.

38. Identify Who Receives the Deposit

The payment recipient matters.

If the seller owns the property but the deposit is requested into an agent’s personal account, the legal basis should be examined.

Every payment should have an identifiable contractual purpose and recipient.

39. Review the Main Purchase Agreement

The agreement should accurately identify the parties and property and regulate the transaction’s essential obligations.

Important provisions may concern the purchase price, deposit, payment schedule, closing date, title condition, mortgage release, delivery, default, cancellation, refund rights and contractual remedies.

The contract should reflect the actual transaction rather than generic sales language.

40. Understand That a Contract Does Not Automatically Transfer Ownership

This is one of the most important concepts for foreign purchasers.

Official investment guidance states that preliminary real estate contracts do not themselves transfer property ownership. Ownership is obtained through registration at the relevant land registry. (Invest.gov.tr)

Therefore, a buyer who has signed a contract and paid money should not automatically assume that they have already become the registered owner.

41. Check Payment Instructions

Before transferring substantial funds, independently verify the payment recipient.

Confirm:

account holder, bank details, payment purpose, amount and currency.

If banking details suddenly change shortly before payment, verify the change through an independent communication channel.

Payment fraud can occur even where the underlying property itself is genuine.

42. Avoid Unexplained Third-Party Payments

A request to transfer the purchase price to an unrelated individual should trigger immediate investigation.

The buyer should understand exactly why that person is receiving the funds and whether payment legally discharges the purchaser’s obligation to the seller.

43. Document Every Payment

Bank transfers should clearly correspond with the transaction.

Preserve payment records, receipts, agreements and communications.

Cash payments create unnecessary evidentiary risk, particularly in high-value cross-border transactions.

44. Check the Title Again Immediately Before Closing

Due diligence should not be treated as a one-time historical event.

Suppose the title was investigated four weeks before closing.

During those four weeks, the owner could potentially become subject to a new attachment or another change affecting the property.

Critical title matters should therefore be checked again as close to closing as practicable.

45. Coordinate Payment With Ownership Transfer

One of the greatest transaction risks occurs between payment and registration.

The purchaser should avoid creating an unnecessary period during which the seller possesses the entire purchase price while the buyer still lacks registered ownership.

Closing mechanics should therefore coordinate payment, release of encumbrances and title transfer.

46. Citizenship-Related Purchases Require Separate Due Diligence

A property may be legally safe to purchase but unsuitable for a particular citizenship investment strategy.

Foreign investors pursuing citizenship should therefore conduct two separate analyses:

Is the property legally safe to acquire?

and

Does the acquisition satisfy the applicable citizenship investment requirements?

Current official investment guidance identifies a minimum qualifying real estate investment of USD 400,000 or its equivalent, subject to the applicable conditions, including the relevant restriction on resale for at least three years. (Invest.gov.tr)

Eligibility should be verified before the transaction is structured around that objective.

47. Residence Permit Objectives Should Also Be Analyzed Separately

Buying property and obtaining immigration status are related but legally distinct issues.

Foreign purchasers should not rely on statements such as:

“Every property automatically guarantees residence.”

The property acquisition should be evaluated separately from the purchaser’s immigration strategy.

48. Agricultural and Undeveloped Land Requires Additional Investigation

Foreign investors purchasing undeveloped property face additional considerations.

Official guidance states that where a foreign individual acquires real estate without an existing structure, the owner must apply to the relevant public authority within two years to develop a project. (Invest.gov.tr)

Land transactions should therefore examine intended use, planning position and applicable foreign-ownership restrictions before acquisition.

49. Commercial Property Requires Use-Specific Due Diligence

A shop, office, warehouse, hotel or other commercial asset should be reviewed according to the business activity intended by the purchaser.

Ownership of the property does not automatically guarantee that every proposed business activity can legally operate there.

Where the investment value depends on a particular use, regulatory feasibility should be verified before purchase.

50. Rental Investment Requires Additional Analysis

Foreign buyers purchasing for rental income should investigate more than ownership.

The review may need to consider the building’s management structure, intended rental model, existing tenant, lease agreement and tax consequences.

Short-term accommodation strategies can involve additional regulatory requirements and should not be assumed to operate under the same rules as ordinary long-term residential leasing.

The Biggest Due Diligence Mistake Foreign Buyers Make

The most dangerous mistake is beginning due diligence after paying the deposit.

The correct sequence is generally:

Property identified → seller verified → title investigated → property-specific legal risks examined → contract reviewed → payment structure established → final title check → payment and ownership transfer.

Many disputes arise because buyers reverse that order. They pay first, sign documents second and investigate ownership afterward.

At that stage, legal counsel may still be able to protect the buyer, but the problem has changed from preventing a loss to recovering money already paid.

Frequently Asked Questions

How do I check whether a property in Turkey has a mortgage?

The property’s current title position should be examined before purchase. Official investment guidance expressly recommends checking mortgages, liens and similar restrictions before beginning title-transfer procedures. (Invest.gov.tr)

Is a copy of the title deed enough?

No. A genuine title document can still be outdated. The purchaser needs to establish the property’s current registered legal status.

Can I check a property online?

Basic parcel information can be accessed through the land registry’s parcel inquiry infrastructure, but public online parcel information does not provide the complete ownership due diligence required for a purchase. (Invest.gov.tr)

Should I check the property again before title transfer?

Yes. Material title information can change between initial due diligence and closing. A final check reduces the risk of acquiring a property affected by a newly registered issue.

Is a mortgage automatically a reason not to buy?

No. A mortgaged property can potentially be purchased safely if the mortgage is fully understood and the release is properly coordinated. The buyer should not rely solely on a promise that it will be removed later.

Does signing the purchase agreement make me the owner?

Not by itself. Official guidance confirms that preliminary contracts do not themselves transfer ownership; acquisition of ownership requires registration through the land registry process. (Invest.gov.tr)

Should newly built properties also undergo due diligence?

Absolutely. Developer purchases can require broader investigation because the buyer may need to examine the underlying land, construction authorization, project financing, mortgages, developer authority and delivery obligations.

Is DASK enough to prove the building is legally and structurally safe?

No. Compulsory earthquake insurance provides specified insurance protection; it is not a substitute for structural or legal due diligence. DASK itself defines its coverage in terms of specified earthquake-related physical losses. (DASK)

Do I need due diligence when buying directly from a famous developer?

Yes. The reputation or size of the developer does not replace property-specific legal review.

When should a foreign buyer instruct a lawyer?

Ideally, before signing a binding agreement or transferring a substantial deposit. Early legal review provides the greatest opportunity to prevent rather than litigate problems.

Client-Focused Legal Support for Property Due Diligence in Turkey

Legal due diligence should not merely confirm that a property exists and that someone claims to own it. A comprehensive investigation should establish who owns the property, whether the seller can legally transfer it, what encumbrances affect the title, whether the physical asset corresponds with its legal documentation, whether the intended use is legally feasible and whether the payment and closing structure adequately protects the purchaser.

For foreign buyers, independent review becomes especially important where the transaction is conducted remotely, the property is purchased from a developer, substantial deposits are required, the seller acts through a power of attorney, the property is mortgaged, or the acquisition forms part of a larger investment strategy.

Fırat Fesih Kaya Law Office assists foreign individuals, overseas investors and international companies with property legal due diligence, title deed investigations, seller verification, mortgage and attachment checks, purchase agreement review, developer due diligence, off-plan acquisitions, remote property purchases, investment property acquisitions and real estate disputes in Turkey.

The safest time to discover a title defect, unauthorized construction issue or seller-authority problem is before the purchase price is paid. For substantial acquisitions, the due diligence findings should also be reflected directly in the purchase agreement through appropriate conditions, seller obligations, representations, refund rights and closing protections.
