Kernrechtsfrage
Whether it was arbitrary to refuse allocating the husband's rent between him and his cohabiting partner when calculating provisional maintenance.
Extrahierter Entscheid
No. Given the husband's substantial housing needs due to shared custody-like visitation and three children, it was not untenable to treat the full rent as his own charge.
Extrahierte Begründung
The housing cost would be incurred regardless of the cohabitation because the father must accommodate three children; unlike basic living expenses, the rent was not reduced by the partner's presence in a legally relevant way.
