Legal analysis: It is illegal for a married daughter not to support her parents. Because it is the legal obligation of adult children to support their parents, parents can ask their children to pay alimony if they fail to fulfill their obligations and cause difficulties to their parents. Children, as supporters, should fulfill the obligations of supporting the elderly economically, caring for the elderly in life and comforting the elderly spiritually, and taking care of their special needs.

Legal basis: Article 26 of the Civil Law of People's Republic of China (PRC) stipulates that parents have the obligation to support, educate and protect their minor children. Adult children have the obligation to support, help and protect their parents. Article 1067 If parents fail to perform their maintenance obligations, minor children or adult children who cannot live independently shall have the right to ask their parents to pay alimony. Parents who fail to perform their maintenance obligations, lack the ability to work or have difficulties in living have the right to claim alimony from their adult children.
