The independent-unit number (bağımsız bölüm numarası) is the legal identifier that separates one condominium unit from another within the same main property. Door plates, sales-unit numbers and marketing floor plans may use different numbering. Before money is committed, the unit number must be revalidated from current TKGM and condominium records rather than inferred from what is written on the apartment door. The objective is to prove that the unit shown, valued, financed and purchased is the same independent unit that will be transferred in the land registry.
Build a three-way match
Match the current title or official registry data, the approved condominium/project information and the physical unit. Record the main property, block, floor where relevant, independent-unit number, land-share entry and unit nature/use. If the project has a commercial internal numbering system, keep it as a separate field and never substitute it for the registered number. The buyer should be able to move from the legal record to the approved plan and then to the actual door without an unexplained jump.
Investigate renumbering
Renovations, project revisions, conversion from condominium easement to condominium ownership, mergers or divisions of units and administrative address changes can create multiple numbers in the file. Determine whether the difference is merely a municipal door number or whether the registered independent-unit identity changed. Obtain the document that connects former and current numbering. A developer spreadsheet saying “old unit 42 = new unit B-17” is not enough if the official records cannot support the link.
Use valuation and contract documents as cross-checks
The sale agreement, valuation report, reservation form and bank documents should all describe the same legal unit. If a valuation report inspected apartment 12 but the title transfer concerns independent unit 21, stop and resolve the discrepancy before relying on the valuation. Likewise, photographs and floor plans should be labelled with the registered unit identity. This is particularly important in projects with mirrored layouts or repeated apartment types, where a visually identical apartment can still be a different legal unit.
Repeat the check before transfer
Revalidate the unit identity after any revised title document, project change, correction request or long delay between contract and closing. On transfer day compare the unit number in the appointment/transaction file with the one previously approved by the buyer. A last-minute change should not be treated as clerical until its official basis is understood. Save the date and source of the final check.
Blocking discrepancies
Do not proceed when the physical unit cannot be tied to the registered unit, when the floor plan points to another unit, when the seller’s contract uses only an internal sales code, or when official records show a different independent-unit number without a documented conversion. Correct the underlying documents first. A strong file leaves no uncertainty about what is being acquired: the legal identifier, the physical apartment, the valuation subject and the contractual subject all refer to one and the same independent unit.
Verify the independent unit against the approved legal configuration
The unit number should be read together with floor, block, use type and the registered condominium project. A door plate, sales-plan label or electricity subscriber number can assist navigation but does not replace the legal independent-unit identity. Where a building has been renumbered, compare the current physical sign with the title and approved project, and document the bridge between old and new numbering. This is particularly important in complexes where several blocks repeat the same apartment numbers.
Escalate any case in which the occupied space appears to combine two units, use part of a common area, or differ materially from the approved configuration. The question is not solved by saying that the buyer has viewed “apartment 12”; the file must show which registered independent unit is being acquired. Revalidation should therefore preserve the title reference, project/floor-plan reference, physical inspection note and any municipal or registry evidence used to reconcile numbering. A later reviewer should be able to identify the exact legal unit without relying on the salesperson who conducted the viewing.
