1. Provide evidence to prove that the relationship between the two parties has broken. This is a legal necessary condition for divorce in litigation. The people's court must also implement the conditions prescribed by law in the trial of cases, and use this as a basis for deciding whether to allow the parties to divorce.
 2. Pay attention to the protection of family property. After one party files a lawsuit, the other party will often move on and transfer the family's common property. Therefore, before the prosecution, do not scare the cat, but collect and sort out the evidence related to the joint property of the husband and wife without showing any signs.
 According to Article 47 of the Marriage Law, if one party conceals, transfers, sells or destroys the joint property of the husband and wife, or forges debts in an attempt to occupy the other party's property at the time of divorce, when dividing the joint property of the husband and wife, the party concealing, transferring, selling, destroying the joint property of the husband and wife or forges debts may be given less or no share. After divorce, if the other party finds that he or she has committed any of the above acts, he or she may file a lawsuit with the people's court to request another division of the husband and wife's common property. The people's court shall, in accordance with the provisions of the Civil Procedure Law, impose sanctions on acts that impede civil proceedings as prescribed in the preceding paragraph.
