Key legal question
Whether the Obergericht acted arbitrarily by not applying Art. 125 ZGB criteria in the separation maintenance assessment
Extracted holding
No. In Eheschutz matters, Art. 125 ZGB criteria are relevant but not controlling to the same extent as in divorce proceedings; the equal sharing of the surplus was not untenable.
Extracted reasoning
The marriage was long and remained formally in force during separation; both spouses had worked full time and no substantiated savings rate was shown.
