The apartment's title deed specifies not only the individual unit but also the share of the land on which the building stands. For buyers in Mersin, this is a useful verification detail, especially when choosing between apartments in different buildings or comparing several offers in the same complex. The fraction in the document doesn't indicate the apartment's area or identify a specific plot of land, but it does help clarify the share of the common property assigned to the property.
Below is a simple explanation of the term and a practical way to compare the information in the tapu with the building documents. This is not a legal opinion on a specific property: if a significant discrepancy or ambiguity is discovered, it is advisable to obtain an independent legal and technical assessment before proceeding with the transaction.
What does a land share in a tapu for an apartment mean?
A share of common ownership of the main land plot allocated to a separate unit in an apartment building. Article 2 of Law No. 634 defines a share of common ownership of the land allocated to a separate unit. According to Article 3, shares are determined proportionately to the value of the units, calculated taking into account their location and size. According to Article 5, the share transfers along with the right to the apartment; it cannot be transferred separately.
In a document, the value may be written, for example, as 12/1000. This is a hypothetical example, not a recommended figure. It represents a share in the common ownership of the plot, not an apartment of 12 square meters or the right to occupy a specific part of the yard. If the total area of the plot is known, a proportional share can be calculated arithmetically, but this does not transform it into a separate, marked plot that the owner can manage independently.
According to Article 16 of Law No. 634, owners own the common areas of the main property in shares corresponding to the arsa payı. Ownership and the rules of use are separate matters: the use of shared garages, terraces, and similar spaces is generally proportional to the share, unless otherwise provided by agreement. The share itself does not assign a separate courtyard space or parking space to the apartment.
Why you can't compare fractions without context
Let's say two tapus indicate different shares. This in itself doesn't prove that one property is better, cheaper, or legally problematic. Comparisons are practical, primarily within the same main plot and building: there, similar apartments can be compared and how the share relates to the location and size of each unit.
For Mersin, this is especially useful when viewing properties in different parts of the city: for example, in Mezitli, Yenişehir, or Erdemli. Apartments in different buildings may have different plot sizes, the number of independent rooms, the number of units, and the layout. Therefore, the fractions from listings at different addresses are not a direct indicator of quality or value.
Don't automatically consider a small share as an error and a large one as an advantage. The value is influenced by the characteristics of the premises and the distribution of shares across the main plot. If the distribution is unusual, consult a specialist to compare the documents and the characteristics of the premises: a single entry in the tapu does not explain the calculation methodology.
How to match the tapu with the house documents
The verification process begins not with searching for a universal "normal" fraction, but with matching property information. Ask to see the current title deed for a specific apartment and documents that allow you to associate it with an independent unit in the building. The name of the district or the apartment number from the advertisement description alone are not sufficient for this.
- Verify that the tapu indicates the exact address and the specific unit you're being shown. Check the unit number and the corresponding block if the complex has multiple buildings.
- Record the plot share size from the tapu record without rounding. Compare fractions in the same format: in the given example, 12/1000 and 6/500 are mathematically equal, even though they are written differently.
- Ask to see the approved architectural design or a list of individual premises, indicating their numbers, locations, and shares. Article 12 of Law No. 634 requires that shares be indicated in the architectural design.
- If a building has multiple units or multiple buildings on a plot, determine which main plot and object the documents apply to. Do not automatically transfer the parameters of one unit to another.
- Compare the apartment to two or three similar properties in the same area. Differences in floor, location, and size can make a difference; comparing it to a property in another area of Mersin is no substitute for such verification.
- If a separate courtyard space, parking, storage room, or other additional space is claimed, clarify how it is listed in the documents. Don't consider it part of your personal property just because the seller or listing describes it as "assigned to the apartment.".
- If there is a discrepancy between the numbers, shares, or ownership of the plot, request an explanation and independent verification before transferring funds or signing the transaction.
What to ask if a share looks unusual
If the share differs significantly from the shares in similar units in the same building, ask for an explanation of the distribution and the document on which it is based. It's best to ask specific questions: does the entry apply to this block? Are the units you're comparing them to the same? Are the renovations or changes reflected in the design documents? The seller's explanation alone is no substitute for verifying the documents.
Don't try to assess the accuracy of the share based solely on the floor or area listed in the advertisement. Article 3 of Law No. 634 links the share to the value calculated based on the location and size of the property, but comparison with the actual property may require verification of the approved project and an expert assessment. If the numbers, numbering, or ownership of the plot don't match, it's reasonable to suspend the registration process until the cause is clarified, rather than assuming the discrepancy will resolve itself once the title is transferred.
In Mersin, this procedure applies to apartments by the sea in Erdemli, apartments in central Mersin, and new homes in Mezitli: the documents for the specific address remain decisive. Don't transfer the shareholder's opinion from one residential complex to another, and don't interpret a high shareholder's ratio as a promise of greater liquidity or appreciation.
What the plot share does not confirm
Even a correctly read share does not replace other property inspections in Mersin. It does not, by itself, confirm that the actual layout matches the approved project, that the area listed on the offer is accurate, that the property is free of encumbrances or debts, or that the building meets all building requirements. These are separate matters with their own documents and procedures.
For an international buyer, it's helpful to split the due diligence into two parts: first, ensure that the property being purchased and its share are truly reflected in the documents, then separately check the legal status, technical condition, and terms of the transaction. If the documents are in Turkish, it's worth obtaining an accurate translation of key entries and an independent consultation with a specialist who can assess the specific situation before signing.
A land share is a small line in the documents, but it's a useful way to check how an apartment relates to the land and common areas of the building. If a specific property in Mersin raises questions about the relationship between the tapu and the project, don't jump to conclusions based on a single number: first, compare all the records related to it.
