(1) The maintenance is to be rendered by making pecuniary payments. The person liable for maintenance may request that they be allowed to render the maintenance in another form if special reasons justify this.
(2) If parents are obliged to pay maintenance to an unmarried child, they may determine in what form and for what period in advance the maintenance is to be paid, provided due consideration is given to the concerns of the child. If the child is a minor, a parent who does not have care for the person of the child may make a determination only for the time in which the child is taken into the household of the parent.
(3) 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.
