Without knowing anything about your child's disability - child support can go beyond 18 years if the child will continue to need support into adulthood due to their disability.

E. Even if a child is over the age of majority when a petition is filed or at the time of the final decree, the court may order support to continue past the age of majority if all of the following are true:
1. The court has considered the factors prescribed in subsection D of this section.
2. The child has severe mental or physical disabilities as demonstrated by the fact that the child is unable to live independently and be self-supporting.
3. The child's disability began before the child reached the age of majority.
