Negotiations in personal injury cases sometimes seem to take forever. There are many subjects that can cause negotiations to reach a deadlock. What causes the accident? What are the effects? Who is liable? What is the loss or damage? Should an expert be consulted, and if so, who? Since 2010 there is a simpler and more efficient way to assess loss. In so-called sub-proceedings only the points on which the parties disagree are presented to the court. Once the court has ruled in the sub-proceedings, the parties can continue their negotiations about compensation. Sub-proceedings are an alternative to the usually time-consuming proceedings on the merits. The liable party pays for the sub-proceedings, in principle.
