Kat İrtifakı and Kat Mülkiyeti: checking a Turkish title deed
Kat İrtifakı and Kat Mülkiyeti describe different legal stages of an independent unit in a building. Neither term alone proves that an apartment is free of legal or construction problems. Check the title, approved plans and occupancy documents together.
What the two terms mean
Kat İrtifakı is condominium servitude: rights linked to a share of land and the planned independent unit. It is commonly associated with the development stage. Kat Mülkiyeti is condominium ownership for an independent unit in a completed building. The framework is set by Condominium Law No. 634, including the published amendments concerning registration and occupancy documents.
An occupied apartment with Kat İrtifakı is not automatically unsuitable. It does mean that the reason for its current status, the documents available and any remaining obligations deserve a clear explanation before purchase.
Where İskan fits in
İskan, or Yapı Kullanma İzin Belgesi, is the building occupancy permit. It is a separate document. Working water, electricity and lifts, or neighbours already living in the building, do not replace documentary checks. Read our İskan guide alongside the title information.
What to compare before signing
- Identity of the property: district, plot, block, independent-unit number and the apartment physically shown to you.
- Ownership and restrictions: current registered owner, mortgages, attachments and other relevant entries.
- Permitted use: whether the unit is legally residential and whether the layout matches the approved plans.
- Building documents: construction and occupancy permits and any explanation for missing or incomplete records.
- Outstanding work: who must complete it, by when and at whose cost.
When to pause the purchase
Pause if the explanation is only “everyone lives here”, the unit numbers do not match, a major alteration has no supporting documents or the seller asks you to accept an undefined future registration. Ask for written evidence and independent legal review.
Mortgage approval, residence-permit eligibility and citizenship qualification are separate checks. A title label does not guarantee any of them. For a property in Alanya, send us the listing reference and your intended use so we can identify which documents need checking before a deposit.
