Abstract: Online trial is the product of the development trend of Internet technology in the field of civil litigation in China. To a certain extent, it provides a more efficient and economic path for the parties to approach justice and realize justice. However, from the perspective of the current application of online court procedure, the lag of legislation leads to the obvious disconnection between its system construction and practical exploration. The construction of online trial rules should follow the current basic principles of civil litigation, fully consider the particularity of its technical means, improve the parties' recognition of the judgment results through the standardization of the trial procedure, and construct the procedural rules with universal significance and relative stability as soon as possible.
