纠纷调查是调解员调解纠纷前最主要的准备工作。调解员通过纠纷调查,对当事人、证人进行走访、询问,收集证据,弄清矛盾纠纷的性质、争执的焦点、产生的原因、发展过程、目前的程度,才能为调解成功铺平道路。 Dispute investigation is the most important preparatory work before mediators mediate disputes. Through mediation of disputes, mediators can pave the way for the success of mediation by conducting interviews with parties and witnesses, querying and collecting evidence, clarifying the nature of conflicts and disputes, the focus of disputes, their causes, the development process and the current level.
