What this check answers

Similar-sounding records answer different questions: ownership, cadastral description, planning and environmental constraints must not be merged.

What to verify

  • KW: ownership and registered rights or encumbrances.
  • EGiB: cadastral identifiers, area, use and soil-class information.
  • MPZP or WZ: the planning basis; separate registers cover flood, nature and infrastructure.
