Child support stops at the age of 18,unless you have it stipulated in the child support order that you are to pay until the age of 21. If that were the case you would know,and it is really rare that the courts allow that,it is usally allowed if both parents agreed to it and put it in their divorce order. When the child or children reach the age of 18 you will need to contact the court house and ask for the child division and report that the child has turned 18,they do not always just stop it on their own.
