Kernrechtsfrage
Whether the Obergericht acted arbitrarily in fixing the husband's 2004 income at about CHF 131,000 despite much higher prior earnings.
Extrahierter Entscheid
No. The income drop was supported by objective indications, especially the new Tarmed tariff and corroborating budget/materials.
Extrahierte Begründung
The court accepted that a self-employed person's relevant income may be the last reliably ascertainable or expected income when a clear trend exists. The finding was not arbitrary and did not involve a misallocation of the burden of proof under Art. 8 ZGB.
