When can a divorced person marry again under Section 15 of the Hindu Marriage Act, 1955?

Under Section 15 of the Hindu Marriage Act, 1955, a divorced person may lawfully marry again when "either there is no right of appeal against the decree or, if there is such a right of appeal, the time for appealing has expired without an appeal having been presented, or an appeal has been presented but has been dismissed". In short, the divorce decree must have become final. A pending appeal bars remarriage, and delivery of the decree or settlement of custody is irrelevant.
