⚖ 50/50 Custody in Colorado
Does Child Support Apply With 50/50 Custody in Colorado?
In most cases, yes. Colorado does not automatically eliminate child support with equal parenting time.
✓General rule: With 50/50 custody, the higher-earning parent typically pays the lower-earning parent. The amount is reduced vs sole custody but rarely reaches $0.

FORMULA How Colorado Calculates Child Support
Colorado Revised Statutes Section 14-10-115 governs child support. Colorado uses Income Shares with published schedule tables. Support ends at 19 or upon emancipation.
AGE When Does Child Support End in Colorado?
Child support in Colorado ends when the child turns 19 — Colorado support ends at 19 — not 18. Support also ends upon the child’s death, marriage or emancipation. Important: In most cases support does not stop automatically — you need a court order. Stopping payments without a court order creates arrears even after the child reaches the cutoff age.
INTEREST Arrears Interest in Colorado
Colorado charges 8% annual interest on unpaid child support arrears. There is generally no statute of limitations on child support debt.
ENFORCEMENT Colorado Child Support Enforcement
Colorado has broad enforcement powers including wage garnishment, tax refund interception, driver’s license suspension, professional license suspension, passport denial, and credit bureau reporting. Criminal charges may apply for significant or long-term non-payment.
MODIFY Modifying Child Support in Colorado
Child support can be modified in Colorado when there is a material and substantial change in circumstances — typically a significant income change, job loss, new children from another relationship, or change in custody. Most states also allow a periodic review every 3 years. File a petition with the court — private agreements to change support are not legally enforceable.
