If the parents agree on modifying child support in Colorado, they can submit a stipulated agreement to the court for approval. This agreement should outline the proposed changes and the reasons for the modification. Once submitted, the court will review the agreement to ensure that it is fair and in the best interests of the child. If the court approves the modification, it will issue an order reflecting the new terms of the child support arrangement. This process can be quicker and less contentious than going through a contested modification hearing.
