Abstract: Family dispute involving emotions and ethics, is thus characteristic of complexity and peculiarity distinguished from other disputes. In family mediation, disputants’ discourse is crucial for presenting facts and opinions while expressing attitudes and intentions, but to date has not received due scrutiny in linguistics. Based on the Attitude System and the Intentionality Theory, this study scrutinizes disputants’ discourse in family mediation, with an aim to reveal how attitudinal resources are employed to manifest disputants’ intentionality. The results indicate that disputants use various resources of Affect, Judgement and Appreciation to demonstrate their attitudes and manifest their intentionality. Their intention in discourse may reflect their prior intention either directly by explicit appraisal lexis or indirectly by implicit appraisal clauses or rhetorical devices.
