Legal analysis: No, both parents can change their children's names through consultation. If negotiation fails, neither party may change the original name without authorization. After divorce, if either parent unilaterally changes the child's surname without the permission of the other parent, and the biological father or mother raises an objection, the other parent shall restore the child's original surname.
Legal basis: Article 10 12 of the Civil Code of People's Republic of China (PRC) states that natural persons have the right to name, and have the right to decide, use, change or allow others to use their own names according to law, but they must not violate public order and good customs.
