Austrian (divorce) law recognizes two types of divorce: fault divorce and divorce on other grounds.
The principle of fault is based on the fact that it is no longer reasonable for the blameless partner to live together because the other partner has grossly violated the obligations arising from the marriage through fault.
A marriage is incurably broken if the marital union has already broken down to such an extent that it can no longer be expected that a union corresponding to the essence of marriage will be resumed (principle of breakdown). Pure fault on the part of one spouse is not sufficient—a breakdown must always occur.
