According to the provisions of China's marriage law, marriage must meet the following four conditions: (1) It must be completely voluntary by both men and women. Article 5 of the Marriage Law stipulates: "Marriage must be completely voluntary by both men and women, and neither party may force the other, and no third party may interfere." Therefore, a man and a woman should not attach any conditions to their marriage. Marriage is the true expression of the parties. If you make a wrong expression of consciousness because of coercion or deception, or make a wrong expression of consciousness because of a major misunderstanding, such a marriage is invalid. (two) must reach the legal age of marriage. Article 6 of the Marriage Law stipulates: "The age of marriage shall not be earlier than 22 for men and 20 for women. Late marriage and late childbearing should be encouraged. " The legal age of marriage is mandatory, you must reach the legal age to get married, and the age of late marriage can only be a call and encouragement. In order to meet the requirements of family planning, the state encourages people to get married later and makes promotional provisions, which are not legally binding. People can consciously abide by it through positive publicity and education, and cannot restrict people from getting married late. If one or both parties fail to reach the legal age for marriage and practise fraud in marriage registration to obtain a marriage certificate, once found, the marriage registration authority shall declare the marriage invalid and withdraw the cheated marriage certificate. If the circumstances are serious, legal responsibility shall be investigated. (3) Monogamy. Article 2 of the Marriage Law stipulates: "The marriage system of freedom of marriage, monogamy and equality between men and women shall be practiced." Therefore, the parties who ask for marriage can only be unmarried, widowed or divorced. People with spouses can remarry only after the original marriage relationship is terminated. The criminal responsibility of bigamy should be investigated. Divorced couples who want to remarry must not remarry, or their spouses have died after remarriage, or divorce after remarriage. (4) There is no law prohibiting one or both parties from getting married. Article 10 of the Marriage Law stipulates that one cannot get married under any of the following circumstances: First, one cannot remarry; Second, lineal blood relatives and collateral blood relatives within three generations are prohibited from getting married; Third, before marriage, I have diseases that doctors think should not be married. A marriage with this disease is invalid if it is not cured after marriage. Suffering from diseases that are medically considered unsuitable for marriage before marriage refers to mental illness and major incurable infectious diseases or hereditary diseases.

Those who meet the requirements of this law shall be registered and issued a marriage certificate. The marriage relationship is established when the marriage registration is completed. Those who have not registered for marriage shall re-register.
