Recording and processing of personal data

The Kadaster keeps track of which rights apply to registrable property in public registers and the key register of the Kadaster. This is a statutory duty. Anyone who wants to assert a right to immovable property (e.g. a house), ship or aircraft is obliged to register the accompanying documents.

If you purchase or sell a house, you will go with the seller or buyer to the notary to sign the deed of delivery. The notary will send a copy of the deed to the Kadaster. We will check whether all required data are in the deed and record the deed in the public registers. Only once this has occurred, has ownership legally been transferred. As a result of the document in the public register, the key register will be updated. The buyer and seller will receive a letter (notification) from us. With this notification, we will let you know that the data in the key register have changed.

Which personal data are registered?

The Kadaster records, inter alia, the following data:

  • personal details of the buyer: such as name, address and date of birth, gender, and partner data if applicable, marital status;
  • the rights the buyer has with regard to registered property: such as ownership or building rights;
  • reference to the registered documents in the public register;
  • plot number, address and description of the registered property;
  • transaction data: transaction date and purchase price;
  • mortgage details: details of the mortgagor and the principal sum.

For what does the Kadaster use personal data?

The Kadaster provides legal certainty with real estate, ships and aircraft. It is important for legal certainty that the data in the register are public: everyone can consult who is an owner or who has other rights. Personal data can also be viewed by everyone. Viewing means that the data can be requested per address or plot number. Authorised users, such as a notary or bailiff, can also request data by name (i.e., what does this person have registered in their name).

The Kadaster only uses registered personal data to perform its legal duties as set out in the Land Registry Act. For example, the Kadaster uses your name and address to send you a notification of changes to the register or to send you an invitation in order to designate a new border. The Kadaster may perform statistical analyses on data in the register, but ensures that results cannot be traced back to individual persons.

In order to monitor the quality of your data and to ensure that the data are correct, Kadaster checks your data in the BRP (Key Register of Persons). The Kadaster uses your Citizen Service Number, inter alia, for this purpose. The Kadaster may do this in connection with maintaining the public registers and the key register. This use is permitted on the basis of an authorisation issued by the Minister of the Interior and Kingdom Relations.

Does the Kadaster also provide bulk data?

The Kadaster provides bulk data to, inter alia, government organisations for performing their public duties, such as taxation and spatial plans, and to investigative authorities in connection with possible investigations into (property) fraud. The Kadaster will only provide a Citizen Service Number to government agencies if this is necessary for the performing their public duties.
The Kadaster also provides bulk data to property managers, such as housing corporations if it concerns their property, or to utility companies if it concerns plots for which they preside over a building right.

On request, the Kadaster will provide information from the public registers and registration for scientific, historical and statistical surveys. In this context, personal data are anonymised as much as possible in order to guarantee the privacy of those concerned.
The Kadaster does not provide bulk data for direct marketing for commercial or charitable purposes. Data are also not provided for profiling or making decisions based on automated processing.

How long does the Kadaster keep my data?

The data in the Kadaster register are kept permanently. Under the Public Records Act, data are transferred to the National Archives after 20 years. However, they are also kept at the Kadaster.
