Incorrect Apartment Number on a Turkish Title Deed: Correction for Foreign Owners 2026

Does your Turkish title deed show the wrong apartment or independent-unit number? Learn how foreign property owners can correct title registry errors, project mismatches and apartment-number mistakes in Turkey in 2026.

A foreign buyer may purchase an apartment in Turkey, receive the keys, move into the property and only later discover a serious discrepancy: the apartment number shown on the title deed does not correspond to the apartment they physically occupy.

For example, the buyer may believe they purchased Apartment 12, while the title registry identifies the owned independent unit as No. 11. In another case, the door number may be correct but the approved architectural project identifies the independent unit differently. Sometimes several apartments in the same building have been systematically numbered incorrectly.

This should not be dismissed as a minor clerical issue.

Under Turkish property law, the decisive question is not simply which number appears on the apartment door. The title registry, approved architectural project, independent-unit plan, floor, location, land share and physical use of the property must be compared.

The Turkish Land Registry and Cadastre authority has a specific administrative framework for correcting erroneous block and independent-unit numbers. Its official guidance recognizes procedures based on technical reports and approved independent-unit plans, followed by registry correction when the applicable consent requirements are satisfied.

For a foreign owner, the first step is therefore:

Do not assume that changing the number written on the title deed alone will solve the problem. Determine exactly where the error originates.

What Is an Independent Unit Number?

In a condominium building, each separately registered apartment, office, shop or similar unit is identified as an independent unit.

The title registry may contain identifying information including:

• Main property
• Block
• Parcel
• Building or block
• Floor
• Independent-unit number
• Property type
• Land share
• Ownership information

The Land Registry and Cadastre authority also treats block and independent-unit numbers as information identifying a property.

Accordingly, the independent-unit number is not merely a postal address.

It helps identify the legally registered property.

Door Number and Title Deed Number May Be Different

This distinction is essential for foreign buyers.

The number displayed on the apartment door may be a municipal address or building-management number.

The independent-unit number recorded in the title registry may be different.

Therefore:

Door says 15 + title deed says 12 ≠ automatically a title registry error.

Before requesting a correction, the owner should compare the title deed with the approved architectural project and official independent-unit plan.

How Does an Apartment-Number Error Usually Arise?

Incorrect registration can result from several situations.

Common examples include:

• Apartments numbered incorrectly during construction
• Two independent units having their practical numbers exchanged
• Incorrect numbering on the architectural project
• Incorrect transfer from project information to the registry
• Block numbers changing during development
• Physical use becoming inconsistent with the approved project
• Earlier owners occupying the wrong units
• Developer handing buyers apartments different from their registered units
• Errors during condominium establishment
• Data-entry or registry errors

The remedy depends heavily on which of these actually occurred.

Example: Foreign Buyer Owns No. 14 but Lives in No. 15

Assume a foreign investor purchases what the developer introduces as Apartment 15.

The sales contract says Apartment 15.

The buyer inspects Apartment 15.

The keys delivered are for Apartment 15.

Years later, a mortgage application reveals that the title deed legally identifies the buyer’s independent unit as No. 14, while another owner holds the registered title to No. 15.

This may not be a simple typographical correction.

The following documents should immediately be compared:

Title registry + approved architectural project + independent-unit plan + sales agreement + delivery records + actual physical occupation.

Only after that comparison can the appropriate correction mechanism be selected.

First Question: Is the Registry Wrong or Is the Physical Use Wrong?

This is usually the most important issue in the case.

There are several possibilities.

Scenario 1: The registry contains a simple clerical error

The underlying official documents correctly identify the unit, but information was entered incorrectly.

Scenario 2: The approved architectural project contains incorrect numbering

The problem originates in the project rather than merely in the registry.

Scenario 3: Owners physically occupy different apartments from the units registered to them

This is more complicated because changing a number may effectively affect the property rights of several owners.

Scenario 4: The developer delivered the wrong apartment

The title registry may actually be correct, while the buyer received possession of another unit.

In this situation, the dispute may involve contractual remedies, title rights or litigation rather than a straightforward registry correction.

Official Procedure for Incorrect Independent-Unit Numbers

The Land Registry and Cadastre authority’s 2019/14 Circular specifically regulates erroneous block and independent-unit number correction procedures.

According to the official guidance, correction of erroneous independent-unit numbers can proceed through a technical-report process or through an independent-unit plan prepared and approved by the relevant administration, depending on the situation.

This is important because the Land Registry Office does not necessarily correct a complex apartment-number mismatch merely because one owner says:

“My apartment number is wrong.”

Technical and administrative documentation may first be necessary.

Technical Report Procedure

Where the official procedure based on a technical report applies, the relevant technical documents and approved independent-unit plan are transmitted to the Land Registry Office through the competent administration.

The official circular states that a notation may initially be entered indicating that the independent-unit number established in the project and the unit’s actual use are inconsistent. Owners affected by the incorrect numbering are then notified.

This provides a structured method for addressing situations where the error affects the relationship between the approved project, physical occupation and registry.

Independent-Unit Plan

The independent-unit plan can become one of the most important documents in the correction process.

It can establish matters such as:

• Unit location
• Floor
• Position within the building
• Independent-unit number
• Relationship with neighboring units

The Land Registry authority’s official workflow specifically refers to an approved independent-unit plan being sent to the Land Registry Office as part of the correction procedure.

Foreign owners should therefore avoid relying only on the title deed or apartment-door number.

Role of the Municipality or Relevant Administration

The problem may require involvement from the authority responsible for the approved building documentation.

Depending on the property and circumstances, official plans and technical documentation may need to be prepared or confirmed before the registry can be corrected.

The official Land Registry procedure contemplates the relevant administration transmitting the approved independent-unit plan and correction documentation to the Land Registry Office.

This is why many cases cannot be solved through a simple handwritten application to the registry.

Do All Apartment Owners Need to Agree?

Sometimes consent becomes a central issue.

According to the Land Registry authority’s official circular, the correction procedure can require the request of all relevant condominium owners or a request by one owner together with the consent of the others. The circular also regulates situations where all independent-unit numbers in the main property or block are erroneous and a unanimous notarized condominium-owner decision may be used under the specified conditions.

The precise consent requirement depends on the scope and type of correction.

Why Consent Matters

Changing independent-unit numbers can affect more than the owner requesting the correction.

Imagine:

Unit 7 becomes Unit 8

while

Unit 8 becomes Unit 7.

Both ownership records are potentially affected.

The Land Registry Office must ensure that the correction does not improperly alter another person’s registered property rights.

Therefore, a multi-unit numbering error is fundamentally different from correcting a spelling mistake.

Mortgage Holders and Other Right Holders

A further complication arises where one or more affected apartments are subject to:

• Mortgage
• Usufruct
• Other limited property rights
• Personal rights recorded in the registry
• Restrictive annotations
• Prohibitory annotations

The official Land Registry circular provides that consent can be required from holders of limited property or personal rights and beneficiaries of prohibitory or restrictive annotations affecting the units being corrected.

Foreign owners should therefore obtain a complete current title-registry record before starting the correction process.

Mortgage Example

Suppose Apartment 20 and Apartment 21 have been incorrectly numbered.

Apartment 20 is mortgaged to a bank.

Correcting the registration may affect how the mortgaged property is identified.

The bank’s rights cannot simply be ignored.

The mortgage and the proposed correction should therefore be analyzed before the application is filed.

What If Another Owner Refuses to Consent?

This can turn an administrative correction into a property dispute.

For example, another owner may argue:

“The registered apartment is mine, and I do not agree that the records are wrong.”

At that point, the issue may no longer be resolvable through consensual administrative correction alone.

Depending on the nature of the discrepancy, court proceedings concerning correction of the title registry or the underlying ownership rights may need to be considered.

The exact claim should be selected only after comparing the official project and registry history.

Simple Registry Mistake Versus Ownership Dispute

This distinction can save substantial time.

A straightforward registry error may potentially be corrected administratively.

But if the proposed “correction” would effectively transfer ownership of one apartment to another person, the issue cannot safely be treated as a simple clerical amendment.

Ask:

Will the correction merely fix identification information, or will it change who legally owns which physical apartment?

If ownership changes, the legal analysis becomes substantially more serious.

Title Registry Correction Litigation

Where the registry does not reflect the legally correct property situation and administrative correction is unavailable because the matter is disputed, judicial correction may become necessary.

The court will need to determine the actual legal basis for the requested change.

Relevant evidence can include:

• Current and historical title records
• Architectural project
• Independent-unit plan
• Condominium establishment documents
• Sales agreement
• Developer records
• Delivery documents
• Construction records
• Municipal records
• Expert examination
• Physical inspection

A lawsuit should not be filed merely on the basis of the door number.

Developer Delivered the Wrong Apartment

Sometimes there is no title registry mistake at all.

Suppose a foreign buyer legally acquired Apartment 8, but the developer mistakenly delivered the keys to Apartment 9.

The buyer has lived in Apartment 9 for three years.

The title deed still correctly identifies Apartment 8.

Calling this a “registry error” could lead the owner in the wrong direction.

The underlying issue may instead involve incorrect delivery, contractual non-performance and competing property rights.

Sales Contract Is Crucial

Foreign buyers should preserve the original purchase documentation.

Important records can include:

• Reservation agreement
• Preliminary sale agreement
• Notarized agreement where applicable
• Final sale documentation
• Payment receipts
• Brochure
• Floor plan
• Developer correspondence
• Apartment selection form
• Delivery protocol
• Photographs

These records may show exactly which physical apartment the buyer intended to acquire.

Marketing Number Versus Legal Independent-Unit Number

Developers sometimes market units using commercial numbers that do not correspond perfectly to final registered independent-unit numbers.

For example:

Marketing Apartment A-1204

may later correspond to a different official independent-unit identifier.

That is not automatically unlawful.

The key question is whether the contract and official documents make clear which physical and legally registered property was sold.

Wrong Floor Information

The problem may involve both the apartment number and floor.

For example:

Title registry: Floor 5, Unit 18

Physical apartment: Floor 6, Door 18

This requires examination of the approved project and building numbering system.

Do not assume that everyday descriptions of floors correspond exactly to project terminology.

Wrong Block Number

Large residential projects frequently contain several blocks.

A foreign buyer may discover that the title deed identifies Block B while the apartment physically occupied appears to be in Block C.

The Land Registry authority’s 2019/14 Circular also specifically addresses erroneous block-number corrections.

Block errors can affect many owners simultaneously and should be investigated at project level.

All Apartments in the Building Are Incorrectly Numbered

This can occur where the building was occupied using one numbering sequence while the approved project uses another.

The official workflow expressly contemplates cases in which all independent-unit numbers in a block or main property are erroneous. Under specified conditions, a unanimous notarized owner decision and manager application may form part of the correction process.

A coordinated building-wide correction may therefore be more appropriate than dozens of inconsistent individual applications.

Can One Foreign Owner Start the Process?

Potentially, yes.

The official procedure contemplates applications involving one owner together with the necessary consents in qualifying situations.

However, where the correction affects other units, those owners’ rights cannot simply be bypassed.

What If the Foreign Owner Lives Abroad?

Living outside Turkey does not mean the owner must ignore the problem until returning permanently.

Depending on the procedure, the owner may act through an appropriately authorized representative.

The power of attorney should be drafted for the actual transactions required rather than using vague language that may not cover registry, administrative or litigation steps.

Formalities for a foreign-issued power of attorney depend on where and how it is executed, so country-specific requirements should be checked.

Identity Information Must Also Be Correct

A foreign owner may discover both:

• Wrong apartment information
• Incorrect spelling or identity information

These are different correction issues.

The Land Registry and Cadastre authority states that registry identity errors can be addressed through applications made through its available application channels under the relevant title-registry correction framework. It also notes that fee treatment can depend on whether the error originated with the administration or from documents submitted by interested persons or other authorities.

The property-identification problem should nevertheless be handled separately from the owner’s personal identity correction.

Does the Foreign Owner Have to Pay a Fee?

Fee treatment depends on the type and source of the error.

The Land Registry authority expressly states, in the context of registry corrections, that corrections of errors originating from the authority itself are not subject to title deed fees and revolving-fund charges, while errors originating from submitted documents or other authorities may be treated differently.

For a complex independent-unit correction, the owner should determine the applicable fees from the exact procedure rather than assuming the correction is always free.

Can the Apartment Be Sold Before the Error Is Corrected?

Technically possible transactions depend on the current registered status, but selling before resolving a serious unit-identity discrepancy can create substantial risk.

A prospective buyer may discover during due diligence that:

The seller shows Apartment 14 but legally owns Apartment 13.

This can lead to:

• Buyer withdrawal
• Price reduction
• Mortgage rejection
• Contract dispute
• Misrepresentation allegation

Correction before sale is generally far safer where a genuine registration discrepancy exists.

Mortgage Applications

Banks typically need certainty about the exact property serving as collateral.

An apartment-number mismatch can create problems during:

• Valuation
• Mortgage registration
• Property inspection
• Legal due diligence

If the appraiser physically inspects one apartment while the title documents identify another, the financing process may stop until the discrepancy is explained.

Foreign Buyer Due Diligence

Apartment-number problems are an excellent example of why foreign buyers should not rely solely on seeing a title deed before purchasing.

Pre-purchase due diligence should compare:

Title record → Architectural project → Independent-unit location → Floor → Block → Land share → Physical apartment.

The physical apartment should be matched to the registered legal unit before payment is completed.

Does an Incorrect Apartment Number Affect Citizenship Applications?

Foreign property investors using real estate in connection with citizenship procedures should be especially cautious about unresolved title discrepancies.

The property relied upon in an official investment process must be identifiable from the official records.

An unresolved mismatch between the physical property and registered independent unit can create additional due-diligence and valuation issues.

The specific effect depends on the individual application and should be reviewed before relying on the property.

Incorrect Land Share as Well

Sometimes the apartment-number investigation reveals another problem: the land share allocated to the unit may also be disputed.

Apartment number and land share are different issues.

Correcting the independent-unit number should not automatically be assumed to correct an incorrect land share.

Each discrepancy requires its own legal and technical analysis.

Unauthorized Construction

Another complication arises where the physical apartment differs from the approved project because walls, terraces, common areas or unit boundaries were changed after construction.

In such a case, the problem may not simply be incorrect numbering.

It may involve:

• Unauthorized alteration
• Project inconsistency
• Common-area occupation
• Building-law violations
• Condominium disputes

A technical inspection may therefore be essential before requesting a registry correction.

Building Registration Cases

The Land Registry authority also maintains specific guidance concerning correction of block and independent-unit numbers in properties affected by the building-registration framework.

These cases can involve additional documentation and should not automatically be treated in the same way as an ordinary condominium numbering error.

What Documents Should Be Collected?

A foreign owner should normally begin by collecting:

1. Current title deed.
2. Full current title-registry record.
3. Approved architectural project.
4. Independent-unit plan.
5. Building or block plan.
6. Condominium documents.
7. Sales agreement.
8. Payment records.
9. Delivery protocol.
10. Developer correspondence.
11. Apartment photographs.
12. Door-number information.
13. Municipal records where relevant.
14. Mortgage and annotation information.
15. Records relating to neighboring affected apartments.

This package helps identify where the discrepancy actually began.

Technical Expert Examination

In complex cases, a technical expert may need to compare the physical building with the approved project.

Important questions include:

Which physical apartment corresponds to the registered independent unit?

Are only the numbers wrong?

Are the apartment positions wrong?

Were project changes made?

Are several owners occupying each other’s units?

The answer determines whether administrative correction is realistic.

Do Not Exchange Apartments Informally

Suppose two foreign owners discover that they are occupying each other’s registered apartments.

They should not simply agree:

“We will keep living where we are and change the door numbers.”

Physical occupation does not automatically rewrite the title registry.

Any correction or transfer affecting registered ownership should be carried out through the legally appropriate procedure.

Do Not Sign a New Deed Before Understanding the Error

Developers sometimes attempt to solve old problems by asking owners to sign new documents quickly.

Before signing:

• Compare the units
• Check mortgages
• Check annotations
• Check land shares
• Check values
• Check tax consequences
• Check whether ownership is actually being transferred

A “correction” document can sometimes contain more than a technical correction.

Fraud Risk

Occasionally, an apartment-number discrepancy may reveal something more serious.

Warning signs can include:

• Same physical apartment allegedly sold twice
• Different title deed shown during sale
• Deliberately altered floor plans
• False developer representations
• Buyer deliberately directed to a different unit
• Concealed mortgage on the registered unit

These facts may require consideration of civil, property and potentially criminal remedies.

A genuine numbering error and deliberate real-estate fraud should not be treated as the same problem.

Can Compensation Be Claimed?

Potentially, depending on the source of the problem and resulting loss.

For example, a buyer may suffer loss because:

• The actual registered apartment is smaller
• It has a worse view
• It is on a different floor
• Its market value is lower
• Mortgage financing fails
• Resale is delayed
• The developer delivered a different unit

The available claim depends on the contract, responsible party, evidence and applicable limitation periods.

Correction of the registry does not automatically eliminate every compensation issue.

2026 Legal Position

As of 2026, the Land Registry and Cadastre authority continues to publish its 2019/14 Circular and related workflow specifically addressing erroneous block and independent-unit number correction procedures.

The official procedure recognizes technical-report and approved-plan mechanisms, notifications to affected owners, consent requirements and protection of registered limited rights and restrictive annotations.

There is therefore no basis for assuming that every incorrect apartment number requires an immediate lawsuit.

The correct sequence is generally:

Identify the discrepancy → Compare registry and project → Obtain technical documentation → Determine affected owners and rights → Attempt the applicable administrative correction → Consider litigation if the ownership or correction is genuinely disputed.

25 Steps for Foreign Owners Who Discover the Wrong Apartment Number

1. Obtain the current title record.
2. Do not rely only on the title deed copy.
3. Obtain the approved architectural project.
4. Obtain the independent-unit plan.

7. Identify the registered independent-unit number.
8. Compare the physical apartment location.
9. Check the apartment door number separately.
10. Review the purchase agreement.
11. Review the developer’s floor plan.
12. Review the delivery protocol.
13. Preserve payment evidence.
14. Check neighboring units.
15. Determine whether other owners have the same problem.
16. Check mortgages and other registered rights.
17. Determine whether technical reporting is required.
18. Contact the competent administration where necessary.
19. Determine whose consent is required.
20. Avoid informal apartment exchanges.
21. Do not sign developer-prepared correction documents without review.
22. Determine whether administrative correction is available.
23. If consent is refused, evaluate judicial remedies.
24. Assess any resulting financial loss.
25. Resolve the discrepancy before resale or refinancing where possible.

Frequently Asked Questions

1. My Turkish title deed shows the wrong apartment number. Can it be corrected?

Potentially yes. The Land Registry and Cadastre authority has an official procedure for correcting erroneous independent-unit numbers, including mechanisms based on technical reports and approved independent-unit plans.

2. Does a different door number mean my title deed is wrong?

No. A door or postal number can differ from the registered independent-unit number. The approved architectural project and independent-unit plan should first be compared with the title registry.

3. Do I need the consent of the other apartment owners?

Depending on the scope of the correction, consent from other affected condominium owners may be required. The official circular regulates requests by all relevant owners, requests by one owner with the others’ consent and certain unanimous building- or block-level procedures.

4. What if a neighboring owner refuses to agree?

If the disagreement concerns actual ownership rather than a purely technical numbering mistake, administrative correction may not be sufficient. Judicial proceedings may need to be considered after the project and registry records are examined.

5. What happens if an affected apartment has a mortgage?

Mortgage holders and other registered right holders can be relevant to the correction process. The official procedure requires consent from specified holders of limited or personal rights and beneficiaries of restrictive or prohibitory annotations in applicable cases.

6. What if the developer gave me the wrong apartment?

That may not be a title-registry error. The registry may correctly identify the unit you purchased while the developer physically delivered another apartment. Contractual, property and compensation remedies should then be examined.

7. Can I correct the title deed while living outside Turkey?

Potentially, depending on the procedure and authority granted to a representative. A properly drafted power of attorney may be used where legally appropriate, subject to the formalities applicable to the country in which it is issued.

8. Can an incorrect apartment number prevent a sale?

A significant mismatch can complicate due diligence, valuation, mortgage financing and the buyer’s willingness to proceed. Resolving a genuine discrepancy before sale can prevent later disputes.

9. Can I claim compensation from the developer?

Potentially, where the developer’s conduct caused a legally recoverable loss—for example, where a different or lower-value apartment was delivered. The claim depends on the contract, evidence, responsible party and applicable time limits.

10. Should I file a lawsuit immediately?

Not necessarily. The first step should usually be to establish whether the problem is an administrative or technical numbering error, a project inconsistency, incorrect physical occupation or a genuine ownership dispute. The Land Registry authority maintains a specific administrative correction procedure for qualifying block and independent-unit numbering errors.

Legal Assistance for Foreign Property Owners With Incorrect Title Deed Information

An incorrect apartment number can appear minor until the foreign owner tries to sell, mortgage, inherit or legally verify the property. In more complicated cases, the discrepancy may reveal that several owners are occupying incorrectly registered apartments or that the developer delivered a unit different from the one legally purchased.
