After divorce, if no child support is paid, the husband and wife can negotiate. If the negotiation fails, the court can bring a lawsuit. Failure to pay alimony will not lead to imprisonment, but it shall be enforced by the people's court according to law.
 Article 48 of the Marriage Law clearly stipulates that the people's court shall enforce the judgments or rulings on maintenance, upbringing, alimony, property division, inheritance, visiting children, etc. Relevant individuals and units shall be responsible for assisting in the implementation.
 Article 37 of the Marriage Law stipulates that after divorce, one party shall bear part or all of the necessary living expenses and education expenses for the children raised by the other party. The amount and duration of the expenses shall be agreed by both parties; If the agreement fails, the people's court shall make a judgment. The agreement or judgment on the children's living expenses and education expenses shall not prevent the children from making reasonable demands to either of the parents in excess of the original amount of the agreement or judgment when necessary.
