Article 37 of the Marriage Law states that after divorce, for a child supported by one party, the other party shall bear part or all of the necessary living expenses and education expenses. The amount and duration of the expenses shall be agreed upon 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.
