Kernrechtsfrage
Whether the attached situational plan had to be notarized as part of the preliminary contract.
Extrahierter Entscheid
Yes. Because the plan was necessary to identify the land to be sold, it formed part of the contractual object and had to be covered by the notarial certification.
Extrahierte Begründung
Under the cantonal notarization rules, everything that must be certified must be covered by the notary's signature in its spatial position. A plan attached after the notarized text but not signed by the notary is not certified; the exception for mutation plans does not apply to a situational plan attached to a preliminary contract.
