In Colorado, Child Support is based on a formula that considers both party’s incomes, the number of overnights that the children spend with each parent, certain adjustment expenses such as the cost of the children’s share of the medical insurance premiums, work-related daycare and other extraordinary expenses, and other factors.

child supportUnless a court determines that a child is emancipated, Child Support terminates when a child becomes nineteen years old unless one or more of the following conditions exist:

    • The parties agree otherwise in a written stipulation after July 1, 1991;
    • If the child is mentally or physically disabled, the court or the delegate child support enforcement unit may order Child Support, including payments for medical expenses or insurance or both, to continue beyond the age of 19;
    • If the child is still in high school or an equivalent program, Child Support continues until the end of the month following graduation, unless there is an order for postsecondary education, in which case support continues through postsecondary education.

Child custody is modifiable if there has been a substantial and continuing change of circumstances that results in a change in the Child Support Obligation of 10% or more.
