Legally speaking, widowhood means the dissolution of the relationship between husband and wife. She has no obligation to support her husband's parents, and no one can interfere with her right to remarry.

Now China implements the system of freedom of marriage. People are free to fall in love, get married, and of course divorce. It is completely unaffected by other factors, and it is no longer a feudal era in which parents give orders and matchmakers speak. Therefore, the remarriage rate is gradually increasing, and marriage after divorce is clearly stipulated by law.

To sum up, the death certificate of the original spouse is required to continue the remarriage registration.

Legal basis:

Marriage registration ordinance
