Legal analysis: After divorce, if the child goes to college and the parents have the ability to pay, the parents should still bear the necessary childcare expenses. If parents refuse to pay, they can bring a lawsuit to the court.

Legal basis: Article 1085 of the Civil Code of People's Republic of China (PRC). After divorce, if the children are directly raised by one party, the other party shall bear part or all of the support. 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 stipulated in the preceding paragraph shall not prevent the children from making reasonable demands to either parent over the original agreement or judgment when necessary.
