Conflicts are frequent in virtually every scenario involving complex interactions. Collaborative Networks, in which there is a compromise between skills, competencies and resources, are not an exception. Moreover, these conflicts can be different in nature, ranging from cultural or relational conflicts to conflicts of interests. Although conflicts are common in these virtual settings, very few tools exist to settle them. Therefore, parties involved in conflict resolution generally have to resort to traditional approaches, which delay the process and waste the advantages of these Virtual Organizations. In this paper we present a structured model of a contract for a Collaborative Network. Based on this model, we developed an information system which is able to build conflict scenarios and determine the possible and probable outcomes. We combine this development with the UMCourt platform, which comprises a rich negotiation and mediation tool, to build a conflict resolution framework in the context of Collaborative Networks.
