Koçan

A koçan is the title deed: a physical document, and a corresponding entry in the Land Registry, describing a parcel — its number, area, boundaries, owner, and any mortgage or charge registered against it.

In a purchase the koçan eventually moves into your name, a step called tapu devri. Until then what you hold is a registered contract of sale. That gives you a recorded interest in the plot, but it is not ownership.
