In Australia, before a divorcing couple can have their case heard by the Family Court, they must undertake mediation. Thus it is useful to develop information technology tools to support negotiation and mediation in family law. Most negotiation support systems focus upon integrative bargaining. In doing so, they tend to ignore issues of fairness. In Australian Family Law, the interests of the children, as opposed to those of their parents/guardians, are paramount. We investigate the use of providing BATNAs and integrative bargaining in providing family mediation decision support. The discussion is highlighted with examples taken from the domain of Australian Family Law.
