The combination of ligation is slightly discussed in China, but the research on the objective preliminary combination of litigation is not deep enough, and the legislation is also in a blank state. The objective preliminary combination of ligation is different from the combination of claims. It is conducive to reducing the litigation burden of the parties and ensuring the stability of the legal order. China’s legislation should gradually introduce and recognize this system on the basis of referring to the experience of developed countries with the rule of law in the civil law system, combined with China’s national conditions and the specific situation of judicial practice. During the trial, the court must respect the plaintiff’s right of disposition and try the case in the order of the main lawsuit first and the standby lawsuit later. Two lawsuits cannot be tried at the same time. The second instance shall be handled separately according to the contents of the parties’ appeal as the case may be.
