Children born out of wedlock can report their hukou, but they have to pay certain social maintenance fees.
 According to Article 25 of China's Marriage Law, children born out of wedlock enjoy the same rights as children born in wedlock, and no one can harm or discriminate against them. A natural father or mother who does not directly support a child born out of wedlock shall bear the living and educational expenses of the child until the child can live independently.
 On the issue of illegitimate children's registered permanent residence, the specific solutions vary from place to place. Generally speaking, in addition to the birth certificate, some areas also need to have their identity notarized when illegitimate children are registered permanent residence. In addition, in areas where birth certificates are required, parents should first pay a certain amount of social support fees at the neighborhood family planning office where their registered permanent residence is located (unplanned birth fines) After the implementation of family planning measures, you can register with the public security organ with the certificate issued by the family planning department.
 Article 3 of the Administrative Measures for the Collection of Social Maintenance Fees stipulates that: "Citizens who give birth to children in violation of the provisions of Article 18 of the Population and Family Planning Law shall pay social maintenance fees in accordance with the provisions of these Measures. The collection standard of social maintenance fees shall be based on the annual disposable income of local urban residents and the annual per capita net income of rural residents as the reference basic standards, and the amount of collection shall be determined in combination with the actual income level of the parties concerned and the circumstances of not complying with the laws and regulations to give birth to children. The specific standards for collecting social maintenance fees shall be formulated by provinces, autonomous regions and municipalities directly under the Central Government. "
 For example, Beijing's regulations on birth registration of children born out of wedlock: those who give birth beyond family planning or out of wedlock in violation of laws and regulations must hold the Birth Medical Certificate filled and issued by the birth hospital, the Resident Register, Resident ID Card and Marriage Certificate of the father and mother of the baby The certificate certificate and the "Receipt of Collection of Social Maintenance Fees" issued by the family planning department of the place where the mother's household registration is located.
