Abstract: Written testimony is an effective way for appraisers to testify in court, and it is a model that provides justice and efficiency in litigation. In view of the weak research on written testimony system in theoretical and practical circles, it is necessary to define the concept, characteristics, theoretical and practical significance of the written testimony system. On this basis, a full analysis on whether the written testimony system is necessary and feasible to exist under the current judicial system is carried out. At the same time, in the rational construction of the written testimony system, in addition to clarifying basic matters such as the scope and procedures of the appraiser’s appearance in court, it is also necessary to make clear the legal responsibility of an appraiser’s refusing to testify in writing, and provide a supporting system to ensure the effective implementation of the appraiser’s written testimony system，carry out a comprehensive analysis and determination, and finally establish a complete appraisal system for written testimony.

Key words: forensic appraisal, appraiser, way of appearing in court, written testimony
