Since modern times, with the continuous impact of ideas of personalautonomy, equality and freedom, autonomy of will has expanded from the
original property behavior to the behavior of kinship status, which is precisely
integrated with the ethical nature of the kinship relationship itself. The strong
instrumentalism of the autonomy of will and the prior ethics of humanity have
their own shortcomings, but they cannot complement each other. The autonomy
of will is restricted and restricted by ethics, morality, and the maintenance of
marriage and family by the marriage and family law in the behavior of relatives.
The hysteresis and stability of ethics and morals themselves are gradually
emerging in the current era of rapid development and social life. Out of touch.
These problems make part of the legal interests in the kinship behavior fail to be
well protected. The intervention of the state coercive force maintains modesty
while properly adjusting the relationship between the two is the focus of this
article.
