Yes. The guideline amount under C.R.S. § 14-10-115 (as amended by HB 25-1159, eff.

Apply through the Colorado child support agency or the family court in your county. Existing orders can be modified on a substantial change in circumstances - typically a significant income change, job loss, or a change in custody.
