In 2026, enforcement often starts with wage withholding, because income assignments can collect ongoing support and arrears directly from paychecks. Colorado Child Support Services also lists tools like intercepts, credit reporting, and license suspensions or denials, depending on the facts of the case. If the other parent is willfully not paying, contempt of court can be an option, and Colorado provides court forms for requesting a contempt citation. The fastest path depends on whether payments are already set up through an employer, whether the payor is self-employed, and whether there is an existing arrears balance. Keep a payment history, copies of the order, and any proof of nonpayment, because enforcement is document driven. A child support attorney can help choose the remedy that matches the payor’s income source so enforcement actually works in real life.
