The cadastral register is Denmark’s official register of all land parcels — a geographic division of all land into numbered land parcels. Your cadastral number precisely identifies your plot and its boundaries in the official land register.
Why does it matter to you?
The cadastral number is the basis for all legal matters relating to your property:
- Title deeds reference the cadastral number
- Building permits are attached to the land parcel
- Easements are registered against the land parcel
- The municipality calculates your site coverage ratio based on the land parcel area
Boundary disputes with neighbours are resolved by comparing the cadastral map with the actual physical boundaries.
How it works
The cadastral register is administered by the Danish Geodata Agency and is freely available at kortforsyningen.dk and the national data platform Datafordeleren. You can find your cadastral number on:
- Your property assessment from the Danish Property Assessment Authority
- Your title deed
- The BBR owner notification
A Danish cadastral number typically looks like this: 12b, Utterslev By, Brønshøj — consisting of a number, optional letter, local area name and parish name.
The cadastral map
The cadastral map shows the precise boundaries of all plots. It’s relevant for:
- Boundary disputes with neighbours
- Fence and hedge disputes
- Applications for a boundary survey
Note: the map boundary may not always match the physical fence or hedge — historical errors are possible.
Frequently asked questions
What is a cadastral district?
A cadastral district is the geographic unit that groups land parcels together — typically corresponding to a village or urban area. “Utterslev By, Brønshøj” is a cadastral district.
Can I change my plot boundaries?
Yes, through a boundary survey carried out by a licensed land surveyor. It requires agreement from neighbours and registration with the Geodata Agency.
What is an unregistered plot?
Roads and public areas are typically unregistered — they don’t form part of the private cadastral register.
