Legal analysis: First, when the court serves a summons on you, if there is no special reason, you'd better sign for it, because whether you sign for it or not, the subsequent proceedings will continue as usual. If you don't sign the subpoena, the subsequent lawsuit will be against you. In short, respond positively and avoid passive warfare. Second, after signing the summons, you must personally go to the court that issued the summons to know the case as soon as possible. Because you are a party, you have the right to check the other party's complaint against you and the relevant evidence materials submitted. This is very important, because if you want to answer or even counterclaim, you must refute the evidence of the other side. Third, get the relevant materials of your participation in the litigation from the court: notice of rights and obligations, notice of responding to the lawsuit, notice of proof and so on. Fourth, after understanding the basic situation, it is best to consult a lawyer and ask him to analyze whether the other party's evidence can prove his claim or whether the other party is likely to win the case. Fifth, according to the lawyer's analysis and the specific circumstances of the case, consider whether to counterclaim or apply to the court for investigation and evidence collection. Sixth, collect and submit favorable evidence materials, and apply for calling witnesses within the time limit of proof. If you want to send counterclaims and materials to the court, it is suggested that you must use the safest EMS courier, and you must leave the courier's delivery certificate as auxiliary evidence for future litigation.
Legal basis: Article 65 of the Civil Procedure Law of People's Republic of China (PRC), the parties shall provide evidence of their claims in time. The people's court shall, according to the litigant's claim and the trial of the case, determine the evidence that the litigant should provide and its time limit. If it is really difficult for the parties to provide evidence within the time limit, they may apply to the people's court for an extension of the time limit, and the people's court shall extend the time limit appropriately according to the application of the parties. If a party fails to provide evidence within the time limit, the people's court shall order it to explain the reasons; If the people's court refuses to explain the reasons or the reasons cannot be established, it may reject the evidence according to different circumstances, or accept the evidence but admonish it and impose a fine.
