Yes, Colorado courts apply the child support guidelines and may impute income when a parent is voluntarily unemployed or underemployed. The guidelines require the court to determine each parent’s income and can use potential income where appropriate. Documentation of work history, earning capacity, and job market conditions can influence this analysis. A change large enough to alter the guideline result by at least ten percent generally meets the substantial and continuing change standard. The Judicial Branch’s guideline materials explain how income is calculated and adjusted. Bringing accurate financial information helps the court make a fair imputation decision if needed.
