If your husband's previous behavior did not lead to the woman's suicide, then you don't have to bear legal responsibility. Under normal circumstances, mistress is only a moral issue and does not involve criminal responsibility. However, if the other party commits bigamy with your spouse, according to the provisions of China's criminal law, it should be sentenced to fixed-term imprisonment of not more than two years or criminal detention. China implements the marriage system of freedom of marriage, monogamy and equality between men and women. Bigamy is a serious damage to the monogamous marriage system. The so-called crime of bigamy refers to the act of bigamy by a spouse, or the act of marrying someone knowing that they have a spouse. In China's criminal law, bigamy can be divided into two types: one is bigamy of a spouse, which means that a married person marries someone else during the marriage relationship; The other is "Marry others knowing that they have a spouse", which means that I still marry others knowing that they have a spouse. If the actor is deceived into marriage without knowing that the other party has a spouse, it does not constitute bigamy. The "marriage" mentioned here includes not only defrauding legal procedures to register marriage, but also living together in the name of husband and wife although they are not registered. As long as you get married with a spouse, or marry someone knowing that you have a spouse, whether you cheat legal procedures to register for marriage, but live together in the name of husband and wife, it constitutes bigamy. It should be noted that if one party is bigamous, at the time of divorce, no-fault party can make a claim for divorce damages to the wrong party. If the man is suspected of intentional homicide or negligent death, he needs to bear the corresponding criminal responsibility. You can't answer this question. What is the cause of Xiao San's death, how did it happen, what did that person do in the process of Xiao San's death, what role he played, and so on. I don't know the details and can't answer. It can only be said that there is generally no legal responsibility, and moral compensation can be made to appease her family. However, under special circumstances, it is possible that the man is suspected of committing a crime, such as intentional homicide or negligent death. I suggest you consult an experienced criminal lawyer face to face in the local area and give you an analysis according to the specific situation.
