Contract Interpretation: Parking Space Included in Sale Price

The dispute arose because a seller claimed that a condominium share for a parking space, explicitly included in a notarized property sale contract for a specific price, was not intended to be part of the sale, seeking an additional CHF 40,000. The court determined this was a contract interpretation issue, holding that even formally required contracts must be interpreted using general rules, allowing external circumstances to be considered for determining the parties' mutual actual will. Since the plaintiff failed to prove a contrary, mutual underlying intent among all five contracting parties—especially as the written contract clearly included the share and was read aloud—the court applied objective interpretation, finding that the buyers were entitled to rely on the unambiguous written term, thus dismissing the seller's claim.
