Questione giuridica chiave
Whether the appellate court correctly determined post-divorce maintenance under Art. 125 ZGB using the last shared standard and surplus-sharing method.
Decisione estratta
The appellate approach was compatible with federal law in the concrete case, because it first established the spouses' last shared standard and then applied the statutory maintenance criteria with broad judicial discretion.
Motivazione estratta
The Supreme Court clarified that the surplus-sharing method is not categorically barred for quantifying post-divorce maintenance; it is only unsuitable where it substitutes for the factual assessment required by Art. 125 ZGB. Here, the appellate court properly identified the last shared standard and the relevant financial circumstances.
