Kernrechtsfrage
Whether the husband's maintenance contribution should be reduced because a third party regularly co-used the marital property.
Extrahierter Entscheid
Yes. Under these circumstances, fairness justified relieving the husband from part of the housing burden, while preserving payment of the mortgage interest.
Extrahierte Begründung
The regular co-use of the marital property by the wife's friend meant the husband should not bear the full housing and mortgage costs. The amount of relief had to be fixed according to equity and discretion, taking account of the monthly mortgage interest and the property's rental value.
