Can I modify child support after my my children reach 18 ?

Dear Anonymous,   Assuming that your child is already 18, and has graduated from high school (check the wording on your child support obligation as it may say that child support continues until the child turns 18 or graduates high school, whichever is later, provided the child is still in school and it is anticipated the child graduates before the child's 19th birthday)  your child support should have ended.  Once the child turns 18 you cannot go back to modify child support.  However, if the payor parent owes suspport arrears you should go to court to get a judgment requiring the parent to continue to pay the support the parent failed to pay while the child was still under 18.
