Kernrechtsfrage
Whether the divorce-maintenance award could be modified under changed circumstances after the husband's early retirement.
Extrahierter Entscheid
The required material, lasting, and unforeseeable change in circumstances was not shown.
Extrahierte Begründung
The husband knowingly retired early and accepted the financial consequences of the pension split; the change was neither unforeseeable nor lasting, and any hypothetical income issue was insufficiently argued.
