The end age in Kansas

18. If the child turns 18 while still in high school, support continues automatically until June 30 of that school year. On motion, a court may extend it through the school year in which the child turns 19 if the child is still a real high school student and the parents agreed to or accepted the delay.

Law: K.S.A. 23-3001(b)

Parents can agree in a court-approved written agreement to pay support past 18. In a Kansas order, support automatically goes down as each child emancipates (for example, by one-third when one of three children turns 18).
