Questão jurídica principal
Whether the reduction of the wife's provisional maintenance was arbitrary in light of the findings on her income and expenses.
Decisão extraída
The wife failed to show arbitrary fact-finding or unconstitutional assessment of evidence; the reduction to CHF 1,500 was upheld.
Fundamentação extraída
The complaint was largely appellatory and inadmissible. The cantonal court could infer additional income from the wife's asserted expenses and lifestyle, and she had to substantiate all income sources under the adversarial principle.
