Official facts that control the topic
The first substantive rule for “Audit Trail Reconstruction — Condominium ownership status” is this: Kat mülkiyeti is condominium ownership of an independent unit in a completed building; the independent-unit number, related arsa payı and registry entry are central.
Applied specifically through the “Audit Trail Reconstruction” lens to Condominium ownership status, the official position is more precise: TKGM explains that a building with kat irtifakı and a Yapı Kullanma İzin Belgesi can transition to kat mülkiyeti under the statutory mechanism, including ex officio conversion in specified cases. A kat mülkiyeti entry describes the legal form of ownership but does not by itself prove that the unit is free of mortgages, annotations, debts or technical defects.
What this review changes
Reconstructing the audit trail for Condominium ownership status means explaining how the current position was reached, not simply sorting files by upload date. Event date, document-issue date and file-entry date are different things.
To build the timeline, start with these items: registry status, independent-unit number, floor/type, arsa payı, block/parcel, occupancy permit where relevant to conversion and latest registration date. Connect each change to the issuing authority and triggering event, and explain any gap or version without a clear predecessor.
Documents and data that must reconcile
For “Audit Trail Reconstruction”, the key evidence is: registry status, independent-unit number, floor/type, arsa payı, block/parcel, occupancy permit where relevant to conversion and latest registration date
Scope boundary
Because this record is limited to “Audit Trail Reconstruction”, its boundary matters: Kat mülkiyeti does not automatically mean every alteration is permitted or that the building is free of technical risk.
Record-specific applied review
Reconstructing the audit trail for condominium ownership means showing how the property reached its present kat mülkiyeti registration, not merely copying the final status. The chain may begin with the land and arsa payı, continue through a kat irtifakı stage where applicable, incorporate building completion and occupancy evidence, and then document the event by which the independent section became registered under condominium ownership. The independent-section number and land share should remain the matching thread across all stages so that documents from one unit are not attached to another.
At each dated step, the reviewer records the source and what that source actually established at that time. An older deed showing kat irtifakı and a newer record showing kat mülkiyeti are not automatically contradictory; the missing question is whether the conversion event and continuity of identity can be demonstrated. Current TKGM procedure should also be consulted when procedural rules are material to the conclusion, including the July 2026 amendment concerning Circular 2021/4.
This reconstruction is particularly useful when records are missing or versions conflict. The chain should then be rebuilt from available official evidence: current registry entries, relevant building documents and older records that can be matched by unit identity. Gaps are not filled by assumption. The file should distinguish what is directly proven, what is a supported inference from the dated sequence, and what still requires an official document before an independent reviewer could reproduce the history of the ownership status.

Reconstructing the condominium-ownership audit trail
The trail begins with the main property and follows creation of the construction servitude or independent unit, any later conversion to Kat Mülkiyeti, and amendments affecting unit data or share. For every stage identify the source, date and registered right. This explains why an older document may use a different legal term from a current registry extract.
Connect events to the administrative project where the evidence supports it: building permit, project completion, occupancy permission and relevant registration steps, without assuming that one document automatically creates every other legal consequence. If a unit appears in a contract or valuation before the same right appears in the registry, mark the gap and identify the document that completed the transition.
The final chronology should demonstrate that the unit sold today is the same unit that developed through the earlier stages and that changes in share or description are explained. Historical evidence does not replace a current extract, but it explains the relationship between versions and prevents a former project status from being confused with the legal right existing at the time of sale.
