(1) To the extent that a divorced spouse has no maintenance claim under sections 1570 to 1572, they may nevertheless demand maintenance as long as and to the extent that they are not able to find appropriate gainful employment after the divorce.
(2) If the income from appropriate gainful employment is not sufficient for complete maintenance (section 1578), they may, to the extent that they do not already have a maintenance claim under sections 1570 to 1572, demand the amount of the difference between the income and full maintenance.
(3) Subsections (1) and (2) apply accordingly if maintenance was to be granted under sections 1570 to 1572 and 1575 but the prerequisites of this provision have ceased to exist.
(4) The divorced spouse may also demand maintenance if the income from appropriate gainful employment ceases because the spouse, despite their efforts, had not succeeded in securing the maintenance with lasting effect by means of the gainful employment after the divorce. If the divorced spouse had succeeded in securing part of the maintenance with lasting effect, they may demand the amount of the difference between the maintenance secured with lasting effect and the full maintenance.
(5) (repealed)
