Article 1084 of the Civil Code provides for the right of minor children to express their opinions in custody disputes. However, this provision has encountered difficulties in judicial practice, mainly reflected in whether to consult the will of the child, whether the child should attend the trial, the legal nature of the child's opinion, and whether the judge should proactively or passively review the child’s will. These challenges mainly arise from the duality of family cases, the lack of litigation law norms for the consultation mechanism of the minors’ opinion, and insufficient staffing of professional judicial teams. At the same time, the challenges have led to such adverse consequences as inconsistent judgements in similar cases, improper judements, and damage to the interests of minor children. Some jurisdictions of the Anglo-American legal system and the civil law system have made remarkable development in the right of minor children to express their opinions, and the procedure and mechanism of opinion solicitation. China should improve the consultation mechanism for the opinions of minor children on the basis of reviewing judicial practice and drawing on useful overseas experience, implement the principle of the best interests of children, and fully safeguard the legitimate rights and interests of minor children in family litigations.
