The Grundbuch is Germany's official land register: it shows who owns each plot and which rights burden it, and ownership of land passes only when the buyer is entered in it. For a supermarket investor it is the most reliable document in the data room, yet building-authority burdens, contaminated-site records and the lease all sit outside it.
• A current extract, re-checked by the notary immediately before signing, including applications not yet completed.
• Section I: the seller is the registered owner, or its authority to sell is documented.
• Section II: the deed behind every entry, read for its effect on access, parking and any extension.
• Section III: every land charge, and its holder's deletion approval against repayment from the price.
• Plot numbers and areas that match the site plan, the building permit and the lease.
