Kadaster

Kadaster is the Dutch Cadastre, Land Registry and Mapping Agency, a government body responsible for registering property and land, recording property rights and other interests in rem, and maintaining the national cadastral map. Its core role is to provide an authoritative register of who owns which parcels of land and what rights attach to them, including mortgages, easements and leases. The cadastral system defines parcel boundaries, assigns cadastral parcel numbers, and underpins land administration and real estate transactions. When a property changes hands, the deed is registered and the Kadaster updates the land registry accordingly.

In addition to ownership, Kadaster maintains geographically referenced information such as topography and parcel maps. It supplies data to the public and to professionals including notaries, surveyors, real estate agents, planners and government authorities. The agency distributes geospatial data and participates in national geospatial infrastructures and basic registrations for addresses and buildings (BRK), often via open data portals.

Kadaster operates under the supervision of the Ministry of the Interior and Kingdom Relations and serves as an impartial public service provider. Its information supports property transactions, taxation, urban planning, environmental management and infrastructure development. The agency emphasizes data accuracy, accessibility and quality, offering digital services for searching records, requesting extracts and downloading geospatial data to users ranging from individuals to professionals.
