(1) A divorced spouse may demand maintenance from the other, for the care for or child-rearing of a child of the spouses, for at least three years after the birth. The duration of the claim to maintenance is extended as long as and to the extent that this is equitable. Here, the concerns of the child and the existing possibilities of childcare are to be taken into account.
(2) The duration of the maintenance claim is further extended if, taking into account the arrangement of childcare and gainful employment in the marriage and the duration of the marriage, this is equitable.
