Key legal question
Whether the deletion of the registered profit-sharing annotation required the signatures of all heirs of the original seller and, for the deceased spouse, her heirs.
Extracted holding
Yes. The profit-sharing right, including the expectancy, was part of the estate and passed by universal succession to all heirs; therefore all entitled heirs had to join the deregistration request.
Extracted reasoning
The court followed BGE 112 II 300 and held that a suspensive contingent claim is an asset and inheritable. The earlier contrary reading from BGE 105 II 172 was treated as outdated. The contractual wording 'for the seller and his heirs' confirmed that the right belonged to the broader heir circle.
