Data processing and your rights in the context of the real estate cadastre
Information from the Official Surveyor's Office in accordance with Art. 13 of the General Data Protection Regulation.
Processing of personal data in the real estate cadastre
General information
According to Section 1 (1) of the State Law on Official Surveying (LGVerm), its task is to collect and verify data for geobasis information throughout the state and to secure land ownership, in particular by forming parcels of land and determining and marking their boundaries.
The data from the official surveying system (geo-base information) must be stored in a geo-base information system and made available for legal transactions and for state, municipal, and private tasks (Section 1 (2) LGVerm).
On the basis of Section 2 (2) No. 2 LGVerm, the collection of data for geobasis information, including building surveying and the determination and demarcation of parcel boundaries, is also carried out by the official surveying office and the land redistribution office of the city of Mainz.
According to Section 10 (1) LGVerm, we are obliged to record factual and legal data on all properties in the real estate cadastre, including data on the owners and leaseholders of the parcels of land.
In order to fulfill these legal obligations, this information on the ownership of land and buildings is permanently stored in the real estate cadastre.
The personal data includes information on owners and leaseholders in accordance with the land register, owners of properties exempt from registration, share ratios, information on special ownership, and their addresses.
Transmission of personal data
Pursuant to Section 13 (2) LGVerm, information about the owners and leaseholders of parcels of land may only be transmitted or made available within the framework of an automated transmission procedure to
- public authorities, insofar as this is necessary for the performance
of their duties, and - persons and bodies outside the public sector, insofar as they demonstrate a legitimate interest in knowing this data and the overriding interests of the persons concerned that are worthy of protection are not impaired.
Use of personal data for property surveys and special allocations
The personal data of owners and leaseholders is provided by the Mainz Municipal Surveying Office and Land Readjustment Office for the purpose of fulfilling their statutory duties under the LGVerm (Local Government Surveying Act) and is used to carry out property surveys and separations.
Property surveys are surveys to determine parcel boundaries, to form parcels, to measure buildings, and to update and further develop the real estate cadastre (§ 3 (4) LGVerm). Subdivisions are divisions of parcels based on data from the real estate cadastre without real estate surveying (Section 2 (4) LGVerm).
In addition to owners and leaseholders, other persons may also be involved in the performance of real estate surveys, e.g., applicants, purchasers, and authorized representatives. Their personal data will then also be processed as part of the administrative procedure.
Use of owner data in the context of updating the real estate cadastre
The results of the property surveys and separations are transferred to the real estate cadastre (update) after completion. Depending on the type and scope of the update, the affected owners, leaseholders, and other persons must be informed of the update to the real estate cadastre.
