Questione giuridica chiave
Whether the maintenance contribution under protective measures could be modified and set at CHF 2,000 per month based on the wife's changed circumstances and imputed income.
Decisione estratta
The cantonal court could not set the wife's hypothetical income at CHF 2,000 without sufficient concrete factual findings on the activity she could reasonably perform and the resulting earnings; the maintenance issue had to be reconsidered.
Motivazione estratta
Although partial work capacity could be assumed, the appellate court lacked adequate factual basis for the amount of the imputed income. Under Art. 179 CC, modification requires essential and durable changed circumstances, and any hypothetical income must be derived first from the type and extent of work reasonably expected, then from the income actually achievable.
