Question: After a court order for child support, and my child is held back a year, can I get him to pay support 1 more year.? Answer: In Virginia, child support has to be paid for any child over the age of 18 who is (i) a full-time high school student, (ii) not self-supporting, and (iii) living in the home of the party seeking or receiving child support until such child reaches the age of 19 or graduates from high school, whichever occurs first. So the obligation goes until your son turns 19, unless you and the father agree otherwise.
