Kernrechtsfrage
Whether the spouse's actual income from her business was correctly assessed for maintenance modification
Extrahierter Entscheid
The appellate court's assessment of the wife's actual income was not shown to be arbitrary.
Extrahierte Begründung
The Supreme Court held that the appellant merely substituted his own view for the lower court's appraisal of the expert report; this did not establish arbitrariness. The burden-of-proof complaint was moot because the fact was deemed proven.
