Kernrechtsfrage
Whether the debtor's retirement at age 62 justified a reduction of spousal maintenance under former law.
Extrahierter Entscheid
The debtor failed to show a new, unforeseeable and unconsidered change in circumstances; the maintenance reduction could not be reviewed further.
Extrahierte Begründung
Under Art. 153 al. 2 aCC, modification requires an important, lasting, unforeseeable change not already contemplated at divorce. The cantonal findings showed that retirement at 62 and its financial consequences were already foreseeable and had been taken into account.
