Question juridique clé
Whether the complaint against the land register office was admissible for correcting an originally unjustified entry and invalid sale.
Solution extraite
No. Because the register entry was based on a missing material legal basis, correction required a land register correction action under Art. 975 ZGB, not a supervisory complaint.
Motifs extraits
The transfer deed itself was defective because a non-entitled seller disposed of land still owned by Frau B. This is an initial lack of legal basis, not a mere clerical discrepancy between valid deeds and the register.
