Legal analysis: From the legal point of view, there is no law in our country that clearly stipulates that a daughter-in-law has the obligation to support her in-laws, and it is not against the law not to support her in-laws. Moreover, daughter-in-law has no legal status in family relations in China. There are spouses, children, parents, brothers and sisters, grandparents and grandparents in the scope of legal heirs stipulated in China's Civil Code. It is in China's civil code that specifically regulates marriage and family that the family relations it regulates mainly include husband and wife, parents and children, brothers and sisters, grandparents and grandchildren. It can be seen that daughter-in-law has no legal status in family relations in China. Support is a paid obligation based on consanguinity and dependence. The meaning of support basically conforms to what we usually call filial piety. In our country's law, in-laws have no obligation to support their daughters-in-law, and under non-specific conditions, daughters-in-law have no right to inherit their in-laws' inheritance. There is no legal basis for denouncing the daughter-in-law for not supporting her in-laws. So the spouse of the supporter is not the legal supporter. Although the law stipulates that the spouse of the supporter should assist the supporter to perform the maintenance obligation, the obligation of assistance is not the maintenance obligation, and this provision only applies to the duration of the relationship between husband and wife. If the supporter dissolves the marriage relationship with the spouse, or the supporter dies, then the obligation of the spouse to assist in the maintenance is automatically lifted.

Legal basis: Article 21 of the Civil Code of People's Republic of China (PRC). Women whose parents have the obligation to raise and educate their children have the obligation to support and assist their parents. Minors or children who cannot live independently have the right to ask their parents to pay alimony when their parents fail to perform their alimony obligations. Parents who are unable to work or have difficulties in living have the right to ask their children to pay alimony when they fail to fulfill their alimony obligations. Infanticide, abandonment and other acts that harm infants are prohibited.
