I take my mother's surname, and now I want my child to take his father's surname. The child's birth certificate is his grandfather's surname, and the police station will not give me an account. how

Article 22 of the Marriage Law: Children can take their father's surname or their mother's surname. According to the reasoning of legal logic, children may not take their father's surname or their mother's surname. Instead of "take your father's surname or your mother's surname."

In addition, Article 99 of the General Principles of the Civil Law stipulates that citizens have the right to name, and have the right to decide, use and change their names according to regulations. Of course, this means that your child has the right to a name, but it also reflects from another level that how to use a name is the freedom of citizens.

As far as I know, there is no such situation in laws and regulations. If you really want your child to take his grandfather's surname, when you register your child, you can ask the police station to issue a written document rejecting the child's surname Li, and then apply for reconsideration to the public security bureau at the next higher level. Let's see what we can get. Of course, it is the road of administrative reconsideration. I don't know if you think it is necessary.

In the past, you could argue with the police about the law. In civil law, if the law does not prohibit it, permission is granted. You asked him to show the legal basis for his refusal. If you can get the police station to argue, then your goal will be achieved soon.
