Swiss Civil Code

¹ If the entry of a right in rem is un­war­ran­ted, a third party who is or ought to be aware there­of may not rely on the entry.

² An entry is un­war­ran­ted if it is without leg­al basis or was made on the basis of an in­val­id trans­ac­tion.

³ A per­son whose rights in rem are in­fringed by such an entry may in­voke its de­fect­ive­ness dir­ectly against the third party act­ing in bad faith.
