(1) If the spouses are living apart, one spouse may demand from the other the maintenance appropriate with regard to the life circumstances as well as the gainful employment and financial circumstances of the spouses; for outlays resulting from injury to body and health, section 1610a applies. If divorce proceedings are pending between the spouses living apart, then maintenance, from the date on which the proceedings become pending, also includes the costs of appropriate insurance for old age and for reduced earning capacity.
(2) The spouse who is not pursuing gainful employment may be required to earn their own maintenance through gainful employment only if this can be expected of them in view of their personal circumstances, in particular by reason of earlier gainful employment, taking into account the duration of the marriage, and having regard to the financial circumstances of both spouses.
(3) The provision of section 1579 nos. 2 to 8 on the restriction or refusal of maintenance by reason of gross inequity is to be applied accordingly.
(4) The day-to-day maintenance is to be rendered by making periodical payments. The periodical payments are to be paid monthly in advance. The person obliged owes the full monthly amount even if the person entitled dies in the course of the month. Section 1360a subsections (3) and (4) and sections 1360b and 1605 are to be applied accordingly.
