What Is the Difference Between Construction Easement (Kat İrtifakı) and Condominium Ownership (Kat Mülkiyeti)?

Short answer: A construction easement (kat irtifakı) is a title right established for the independent units in a building that has not yet been built or finished. Condominium ownership (kat mülkiyeti) is the title type that gives the unit owner full ownership after the building is completed and the occupancy permit is obtained.

The differences between them

• Kat irtifakı: Established if the building does not exist or is not finished. The "land share" and the unit number appear on the title.
• Kat mülkiyeti: After the building is completed and the occupancy permit (iskan) obtained, the kat irtifakı is converted into kat mülkiyeti.

What does it mean for the buyer?

1. In a project where kat irtifakı is established, the buyer can be a registered holder of a land share; this is a stronger title security than a sales promise.
2. If kat irtifakı is not established, the only security is the contract and the title deed annotation.
3. On the move to kat mülkiyeti, the occupancy permit is obtained and the conversion is made at the land registry office.
