Abstract: Family is an important component of the human society and gives full play to the communicative function between citizens and country. Family plays double functions， that is， to safeguard rights of family members and to keep social order. Family right is provided with double attributes of right and power. As individualism is in vogue， the feature of power is being weakened and the feature of right is on the rise in family right. Family runs into serious challenges. To bring family into full play in modern society， we should scan the theory about family rights and reconstruct the system in accordance with social requirements.
