Understanding the type of title deed (Tapu) before buying property in Turkey is one of the most important steps for reducing legal and financial risk. In most cases, a Kat Mülkiyeti title deed offers greater confidence because it confirms individual ownership of a completed property. A Kat İrtifakı title deed can still be a good investment option, particularly in new developments, but buyers should verify whether the building has obtained its Iskan (occupancy permit) and whether all legal procedures have been completed. Before paying any deposit, buyers should always verify the title deed type, ownership status, mortgages, annotations, municipality records, and the property’s legal compliance.

The safest purchase is not determined solely by the title deed type. Buyers should evaluate the complete legal status of the property before signing any reservation agreement or paying a deposit.

Buying property in Turkey involves much more than comparing prices, locations, or expected rental returns. One of the most common mistakes made by foreign buyers is assuming that every apartment with a title deed carries the same level of legal security.

In reality, the type of title deed, whether the building has obtained an Iskan, and whether the property complies with municipal regulations can all influence your ability to obtain financing, resell the property, apply for residency or citizenship, or even connect utilities.

For this reason, experienced investors review the legal documentation before negotiating the purchase price.

In this guide, you’ll learn the differences between Kat Mülkiyeti, Kat İrtifakı, and Iskan, understand the risks associated with each status, and discover the essential checks every buyer should complete before purchasing property in Turkey in 2026.

What is a title deed in Turkey and why does it matter to buyers?

A title deed, known in Turkey as Tapu Senedi, is the official government document proving legal ownership of a property. It is issued by the Turkish Land Registry and officially records who owns the property and the legal details attached to it.

For buyers, the title deed is far more than a certificate of ownership. It provides essential information that helps verify whether the property being sold matches what is being advertised.

A Turkish title deed generally includes:

• The registered owner’s details.
• Province, district, neighbourhood, and parcel information.
• Property type.
• Independent unit number (when applicable).
• Land share allocated to the unit.
• The registered ownership status.

However, buyers should understand that a title deed alone does not guarantee that every legal requirement has been satisfied.

For example, a property may have a valid title deed while still having:

• Outstanding mortgages.
• Court annotations.
• Shared ownership issues.
• Missing occupancy permits.
• Differences between the approved project and the actual construction.

This is why professional due diligence should always extend beyond simply reviewing the title deed itself.

What does a title deed prove—and what doesn’t it prove?

A title deed confirms that ownership has been officially registered with the Turkish Land Registry.

It does not automatically confirm:

• That the building complies with approved architectural plans.
• That an Iskan has been issued.
• That there are no financial obligations attached to the property.
• That previous structural modifications were legally approved.

For this reason, experienced buyers always combine a title deed review with legal and municipal verification before moving forward.

What is Kat Mülkiyeti in Turkey?

Kat Mülkiyeti is the strongest and most complete form of ownership for apartments and independent units in Turkey. It confirms that an individual unit has been officially registered as a separate property after the building has reached the required legal stage for condominium ownership.

For most foreign buyers purchasing a completed apartment, this is generally the preferred title deed type.

With Kat Mülkiyeti, the apartment is legally recognised as an independent property with its own registration, making future transactions such as resale, inheritance, financing, and ownership transfer more straightforward.

Although Kat Mülkiyeti is generally considered the safest title deed status, buyers should never assume that it eliminates every possible risk.

Before completing the purchase, it is still important to verify:

• The registered owner’s identity.
• Existing mortgages or legal annotations.
• The property’s exact independent unit number.
• Municipal compliance.
• Building management debts, if applicable.

A Kat Mülkiyeti title provides a stronger legal position, but it should always be combined with a complete legal review.

What is Kat İrtifakı in Turkey?

Kat İrtifakı refers to construction servitude established before condominium ownership is fully completed. Instead of confirming ownership of a completed apartment, it records ownership rights based on an approved construction project.

This title deed is commonly found in:

• Off-plan developments.
• Buildings still under construction.
• Recently completed projects waiting to complete the final legal conversion process.

Many foreign buyers mistakenly believe that Kat İrtifakı automatically means the property is unsafe.

That is not necessarily true.

Thousands of newly developed residential projects across Turkey are sold under Kat İrtifakı during different stages of construction before eventually converting to Kat Mülkiyeti.

The key question is why the property still holds Kat İrtifakı.

If the building is still progressing normally and the developer has completed all legal procedures according to schedule, the additional risk may be limited.

However, if an older building has remained under Kat İrtifakı for many years without a clear explanation, buyers should investigate carefully before making any commitment.

Is Kat İrtifakı always a bad sign?

No.

A property with Kat İrtifakı can still represent an excellent investment when:

• The construction licence is valid.
• The developer has a strong reputation.
• Construction matches the approved plans.
• The Iskan process is progressing normally.
• The conversion to Kat Mülkiyeti is expected after project completion.

On the other hand, unexplained delays in obtaining Iskan or converting the title deed should encourage buyers to carry out more detailed legal checks before paying a deposit.

What is Iskan and why is it important when buying property in Turkey?

One of the most important documents that foreign buyers often overlook is the Iskan, officially known as the Building Occupancy Permit.

An Iskan confirms that a completed building has been inspected by the relevant authorities and approved for legal occupancy according to the authorised construction licence and approved architectural plans.

In simple terms, it indicates that the completed building has satisfied the necessary administrative requirements to be legally occupied.

For buyers, Iskan plays an important role because it can affect several aspects of property ownership, including financing, resale, utility subscriptions, and the eventual conversion from Kat İrtifakı to Kat Mülkiyeti.

Its presence generally provides additional confidence that the development has progressed through the expected legal process.

What problems can missing Iskan create?

The absence of an Iskan does not automatically mean that a property should be avoided.

However, buyers should understand why it has not yet been issued.

Depending on the circumstances, missing Iskan may lead to:

• Delays in converting the title deed to Kat Mülkiyeti.
• More complex mortgage approval.
• Difficulties with certain utility subscriptions.
• Reduced buyer confidence during resale.
• Questions about whether the completed building matches the approved project.
• Potential municipal compliance issues that require clarification.

For this reason, buyers should always ask for evidence of the building’s legal status before paying any reservation fee or signing a purchase agreement.

Kat Mülkiyeti vs Kat İrtifakı: what is the difference in buyer risk?

Although both title deed types can represent legitimate property ownership, they do not carry the same level of certainty from a buyer’s perspective. The difference lies in the legal stage of the building and the amount of verification required before completing the purchase.

A property registered under Kat Mülkiyeti has generally completed the legal process required for condominium ownership. The independent unit has been officially registered, making ownership clearer and simplifying future resale, financing, inheritance, and property transfers.

By contrast, Kat İrtifakı represents ownership rights linked to an approved construction project rather than a fully established condominium title. While this is common for off-plan and newly completed developments, buyers should confirm whether the building has progressed to the final legal stage and whether all required approvals have been obtained.

The comparison does not mean that Kat İrtifakı should automatically be avoided. Instead, it highlights that buyers should perform additional legal checks before proceeding.

For a completed resale apartment, Kat Mülkiyeti will generally provide greater confidence. For a newly launched development by a reputable developer, Kat İrtifakı may still represent a sound investment provided the project documentation has been thoroughly verified.

Which title deed type is safer for foreign buyers in Turkey?

For most international buyers purchasing a completed apartment, Kat Mülkiyeti is generally considered the safer option.

Because the independent unit has already been officially registered, the ownership structure is clearer, and future transactions such as resale or mortgage applications are often more straightforward.

However, buyers should avoid assuming that Kat Mülkiyeti alone guarantees a risk-free purchase.

Before signing a contract, it is still essential to verify:

• The registered owner’s identity.
• Whether the property is free from mortgages, liens, or legal annotations.
• That the apartment matches the approved project.
• The building’s Iskan status.
• Any outstanding management fees or municipal obligations.

Likewise, a property with Kat İrtifakı should not automatically be rejected. Many newly developed projects remain under Kat İrtifakı during the final stages of legal completion. In these cases, the developer’s reputation, construction progress, licensing, and expected conversion to Kat Mülkiyeti become far more important than the title status alone.

The safest purchase is therefore not determined solely by the wording on the title deed, but by the overall legal condition of the property.

What risks should buyers watch for before signing in Turkey?

One of the most expensive mistakes property buyers make is paying a reservation fee before carrying out proper legal due diligence.

Even an attractive property in a desirable location can expose a buyer to unnecessary risks if essential documents have not been verified.

Before signing any reservation agreement or purchase contract, buyers should carefully investigate the following areas.

Ownership risks

Confirm that the seller is the registered owner of the property and has the legal authority to sell it. If there are multiple owners, ensure that all required parties approve the transaction.

Financial risks

Check whether the property has:

• Mortgages.
• Court orders.
• Liens.
• Seizures.
• Other legal annotations recorded at the Land Registry.

These issues should be resolved or fully understood before ownership is transferred.

Construction compliance

Verify that the completed building matches the approved architectural plans.

Unauthorised extensions, enclosed balconies, or structural modifications may create future legal complications.

If the property still has Kat İrtifakı, ask why the conversion to Kat Mülkiyeti has not yet taken place.

Contract risks

Never rely solely on verbal promises.

Every important commitment—including completion dates, title transfer conditions, payment schedules, and refund terms—should be clearly stated in the written contract.

Most importantly, buyers should avoid paying a non-refundable deposit until the property’s legal documentation has been independently reviewed.

How to check title deed status before buying property in Turkey

Verifying the title deed is not simply about reading the document. It involves confirming that the legal records, municipal approvals, and physical property all match.

A practical verification process includes the following steps:

1. Obtain a recent copy of the title deed.
2. Confirm that the seller is the registered owner.
3. Verify the parcel number, block number, and independent unit number.
4. Check whether the title is registered as Kat Mülkiyeti, Kat İrtifakı, Hisseli Tapu, or Arsa Tapusu.
5. Review the Land Registry for any mortgages, liens, seizures, or legal annotations.
6. Verify the building licence and Iskan with the relevant municipality.
7. Compare the apartment’s current layout with the approved architectural plans.
8. Check for unpaid maintenance fees, property taxes, or other financial obligations.
9. Complete the ownership transfer only through the official Land Registry process.

These checks may appear time-consuming, but they can significantly reduce the risk of purchasing a property with hidden legal or administrative issues.

When is a property still worth buying if the title or Iskan is incomplete?

An incomplete title status or missing Iskan does not automatically mean that a property is a poor investment. In many cases, particularly within reputable off-plan developments, the legal process is still progressing, and the remaining documentation will be completed before or shortly after handover.

The key is understanding why the documentation is incomplete and whether the remaining steps can be completed without exposing the buyer to unnecessary legal or financial risk.

A property may still be worth considering when:

• It is part of a well-established development by a reputable developer.
• The construction licence and approved architectural plans are valid.
• The title deed status is clearly explained and supported by documentation.
• The developer has a strong history of delivering projects and completing legal procedures.
• The expected timeline for obtaining the Iskan or converting from Kat İrtifakı to Kat Mülkiyeti is documented.
• The purchase agreement protects the buyer if legal milestones are delayed.
• The property’s price reflects the additional risk compared to fully completed alternatives.

On the other hand, buyers should proceed with extreme caution—or consider walking away—if:

• The seller cannot explain why the Iskan has not been issued.
• A completed building has remained under Kat İrtifakı for many years without justification.
• Significant differences exist between the approved plans and the completed building.
• There are unresolved mortgages, legal disputes, or municipal violations.
• The seller pressures the buyer to pay a non-refundable deposit before the documentation has been verified.

In many situations, the issue is not the absence of a document itself, but the lack of transparency surrounding it. A professional legal review can often determine whether the remaining risks are acceptable or whether the buyer should continue searching for another property.

What should investors and end-users verify before paying a deposit in 2026?

Paying a reservation fee or deposit is often the point at which buyers become financially committed to a transaction. Before reaching that stage, every important legal and administrative detail should be verified.

Although investors and end-users may have different priorities, both should complete a structured due diligence process before signing any agreement.

For investors

Investors should focus on factors that may influence future resale value, rental demand, and exit opportunities.

Before paying a deposit, verify:

• The property’s title deed type.
• Whether the property has obtained Iskan or is expected to receive it.
• The developer’s reputation and delivery history.
• The property’s resale potential.
• Whether future buyers are likely to obtain mortgage financing.
• Any mortgages, liens, court annotations, or financial obligations recorded against the property.
• Whether the asking price appropriately reflects any remaining legal or construction risk.

A lower purchase price should never be the only reason for accepting additional legal uncertainty.

For end-users

Buyers purchasing a home for personal use should concentrate on legal security and long-term usability.

Before committing to the purchase, confirm:

• The seller is the registered owner.
• The apartment shown during viewings matches the registered independent unit.
• The building has obtained the necessary municipal approvals.
• Utility subscriptions can be established without complications.
• There are no significant unpaid maintenance fees or property-related debts.
• The property’s documentation supports your intended purpose, whether that is permanent residence, rental income, or applying for Turkish citizenship through investment.

Completing these checks before transferring any money can prevent expensive legal disputes and provide greater confidence throughout the purchasing process.

Investor Overview

The type of title deed you purchase can have a significant impact on the security of your investment, but it should never be assessed in isolation. While Kat Mülkiyeti is generally the preferred option for completed properties, Kat İrtifakı can also represent a sound investment when supported by proper documentation, a reputable developer, and a clear path toward legal completion.

Similarly, the presence or absence of Iskan should be viewed as one element of a broader legal review rather than the sole factor determining whether a property is safe to purchase.

Before signing a reservation agreement or paying any deposit, buyers should independently verify the title deed, ownership records, mortgages, legal annotations, construction licence, approved architectural plans, Iskan status, and any outstanding financial obligations.

Taking the time to complete these checks can help you avoid unnecessary legal risks and purchase property in Turkey with greater confidence in 2026.

FAQ

Is Kat Mülkiyeti always better than Kat İrtifakı?

For completed residential properties, Kat Mülkiyeti generally offers greater legal certainty because the independent unit has already been registered under condominium ownership. However, buyers should still verify ownership, mortgages, annotations, and municipal compliance before purchasing.

Can foreigners safely buy a property with Kat İrtifakı?

Yes. Many off-plan and newly completed developments are sold under Kat İrtifakı. The important factor is not the title deed itself, but whether the developer has the required permits, follows the approved plans, and has a clear process for obtaining Iskan and converting the title.

Does every completed building automatically receive Iskan?

Not necessarily. While many completed buildings obtain an occupancy permit, delays or unresolved compliance issues may postpone the process. Buyers should always verify the building’s current status with the municipality instead of relying solely on the seller’s statements.

Can I obtain Turkish citizenship with a property that has Kat İrtifakı?

Potentially, provided the property satisfies all legal requirements of the Turkish Citizenship by Investment Program at the time of application. Because eligibility depends on multiple legal conditions, buyers should obtain professional legal advice before proceeding.

Does Kat Mülkiyeti guarantee there are no legal problems?

No. Although it is generally the preferred title deed type, buyers should still check for mortgages, court orders, liens, ownership disputes, unpaid debts, and any annotations registered against the property.

Should I avoid properties without Iskan?

Not always. Some properties without Iskan may simply be completing the final administrative procedures. However, buyers should understand the reason for the missing permit and ensure there are no underlying legal or construction issues before proceeding.

Should I pay a deposit before checking the title deed?

No. Buyers should complete legal due diligence first, including verifying ownership, title deed status, Iskan, municipal records, and any financial obligations attached to the property. Paying a non-refundable deposit before these checks increases the risk of costly disputes.
