Kernrechtsfrage
Whether the Obergericht acted arbitrarily by allocating all child allowances to the mother during the period of shared child care.
Extrahierter Entscheid
No arbitrariness: even a half-allocation would not change the overall result, only the calculation route.
Extrahierte Begründung
The allowances were deducted from the wife's minimum subsistence; shifting half to the husband would raise her need and lower his, but the husband would ultimately pass the amount back through higher maintenance.
