In Colorado child support terminates automatically, without the need to file a motion to terminate support, upon the last or only child reaching 19 years of age.  However, the following circumstances are an exception to the general rule:

  • The child is mentally or physically disabled.
  • The chid is in high school, or an equivalent program, in which case support continues until the end of the month following graduation.
  • The child marries before turning 19.
  • The child enters active duty military before turning 19.

It is important to note that the child support terminating automatically is only for the last child reaching the age of 19.  If there are still younger children of the relationship for whom support is being paid, the obligor cannot unilaterally stop, or even modify the support.  The obligor must file a motion with the court to modify child support based on a child's emancipation and there being fewer children to support.
