Questione giuridica chiave
Whether the immovable sale contract was void for formal defects because the payment terms were not stated in the notarial deed.
Decisione estratta
No. Under Art. 216 CO, the authentic deed had to cover the objectively and subjectively essential elements of the sale, but the payment modalities were not an essential element of the contract here.
Motivazione estratta
Payment terms concern execution of the price obligation, not the exchange of prestations itself; they may be governed by general rules or later agreement. The canton court wrongly treated unusual payment modalities as a formal requirement.
