Child support and maintenance can be modified when there is a substantial, continuing change in circumstances, and parenting can be modified under the best-interests standard, but you must go back to court.

Divorce orders can change with life. Child support and maintenance can generally be modified when there's been a "substantial and continuing change in circumstances": a significant change in income, a job loss, or, for support, the kind of change the 2026 child support overhaul itself can trigger. (Some maintenance is non-modifiable if the parties contractually agreed to that limitation.) Colorado sets a deliberately higher bar to change which parent the child primarily lives with, usually requiring endangerment or both parents' agreement, to protect the child's stability.

To modify support, you must file a motion and get a new court order. You can't just privately agree to stop or change payments and assume it's binding, because the existing order stays in force until the court changes it, and unpaid amounts pile up as arrears. The same is true for ongoing changes to the parenting time schedule. Agreed upon changes to the schedule should be written, signed by both parties, and filed with the court. Otherwise, the change is not enforceable if there is a future dispute.
