Question juridique clé
Whether the parties concluded a lease despite a written-form reservation in the draft contract
Solution extraite
Yes. The reservation of written form was waived by subsequent conduct, so the lease became binding from 1 September 2006.
Motifs extraits
The parties exchanged contract versions, handed over and accepted the keys, and the tenant requested removal of fixtures and lamps. These acts showed they considered themselves bound before signature and waived the reserved form under Art. 16 OR.
