The author illustrates the complexity of cases mediators are confronted with by using two exemplary cases. Sometimes legal issues deriving from family law, divorce law and criminal law all are disputed at the same time, frustrating and even blocking all parties including their legal counsels who are also part of the conflict-system. When a conflict-system becomes contaminated, often support systems are mobilised. If a mediator wants to play a role in sorting out the process – which is not his fundamental task – it is best to seek co-operation with the legal counsels.
