Kernrechtsfrage
How the divorce agreement's alimony-waiver clause must be interpreted
Extrahierter Entscheid
The waiver was not intended to apply once the child lived under the father's custody; the wife's earnings could then be taken into account.
Extrahierte Begründung
The court applied objective contractual interpretation. The agreement as a whole, including the staged reduction of maintenance, was based on the premise that the mother had custody and that her caregiving burden would decline as the child grew older. That premise failed when custody changed, so the waiver could not remain isolated from it.
