The man who has children born out of wedlock should pay maintenance. If the man does not pay alimony, the children can file a civil lawsuit and ask the plaintiff to pay alimony and education expenses. If the court still refuses to give it after winning the case, it may apply for compulsory execution.

According to Article 25 of the Marriage Law of the People's Republic of China, children born out of wedlock enjoy the same rights as those born in wedlock, and no one may harm or discriminate against them. A biological father or mother who does not directly raise a child born out of wedlock shall bear the living expenses and education expenses of the child until the child can live independently.

Payment method for children born out of wedlock:

1. Children born out of wedlock are actually raised by their biological mothers, that is, they live with their biological mothers.

The biological father of a child born out of wedlock should bear part or all of the necessary living and education expenses of the child until the child can live independently. The amount and method of the burden should be determined by both parents through consultation according to the financial situation of the biological father and mother of the child. If the negotiation fails and the biological father of the illegitimate child refuses to perform it, the illegitimate child or his biological mother may bring a lawsuit to the court to force the biological father of the illegitimate child to perform the maintenance obligation according to law in the form of a judgment.

2. The biological mother of an illegitimate child marries someone else.

If the stepfather is willing to bear part or all of the children's living expenses and education expenses, the living expenses and education expenses of the biological father may be reduced or exempted as appropriate. If the stepfather is unwilling to pay, the child care fee payable by the biological father cannot be reduced.

3. When the biological parents of children born out of wedlock give their children up for adoption.

Then the relationship between the child and the adopter is legal fiction. At this time, children born out of wedlock are raised by adoptive parents, and the relationship of rights and obligations between children and biological parents is lifted, and biological parents no longer bear the obligation of raising.
