1. After unmarried pregnancy, if both parties meet the conditions for marriage, they should apply for a marriage certificate in a timely manner. When applying for a marriage certificate, they will not be fined, but when applying for a birth certificate, they will be fined 300-500 yuan.
 2. If both parties do not meet the conditions for marriage, they must pay social maintenance fees. The specific amount collected will vary according to the level of economic development in different regions and the income difference of the citizens being collected. If the child is supported by one party, the other party shall pay maintenance fees.
 If the other party does not pay the alimony, it can sue the other party to pay the alimony. For the maintenance of children born out of wedlock, the party concerned can request the other party to pay the maintenance fees, but if the other party does not recognize the parent-child relationship, the party concerned should provide relevant evidence, such as identification, of course, in the proceedings to apply for identification. In China, paternity testing is not compulsory. When illegitimate children bring a lawsuit for reasons such as alimony, the defense of the defendant, without exception, is not to admit that the child is his own, or simply not appear in court. If you want to sue, I just don't admit it. What can you do? In this regard, the law has no clear provisions, which leads to the problem of difficult operation in reality. Therefore, in order to fight a successful lawsuit over the maintenance of illegitimate children, under the existing provisions, it is advantageous for the plaintiff to provide sufficient evidence.
