China's law stipulates that divorce should be granted if the relationship between the husband and wife has really broken down and mediation is invalid. That is to say, "the couple's feelings have really broken down" is the legal condition for divorce in litigation marriage in China. Generally speaking, in the actual trial, if the following situations occur, the court will grant the unilateral divorce request after mediation is invalid.
 （1） Domestic violence or maltreatment or abandonment of family members;
 （2） Bigamy or cohabitation of a married person with another person; Bigamy refers to the act of a married person marrying another person. The cohabitation of a married person with another person refers to the continuous and stable cohabitation of a married person with the opposite sex outside marriage, not in the name of the husband and wife.
 （3） The husband and wife have lived apart for two years due to emotional discord; The separation here refers to the husband and wife's artificial interruption of their common economic life, sexual life, mutual support and spiritual comfort.
 （4） Those who have bad habits such as gambling and drug abuse and refuse to change after repeated education;
 （5） One party is declared missing and the other party files a divorce lawsuit; The declaration of a citizen's disappearance refers to the system whereby the people's court declares a person whose whereabouts are unknown for a certain period as missing. The disappearance of one of the husband and wife, in fact, has been unable to perform its responsibilities for the family and spouse. In this case, the court should allow it to unilaterally sue for divorce.
 （6） Other situations that cause marital relationship breakdown.
