Yes, Colorado courts can modify parenting time while leaving decision-making responsibility unchanged if the adjustment serves the child’s best interests. You typically request this by filing a motion to change parenting time, and the court will evaluate current circumstances. The legal standard for altering parenting time is generally the best interests of the child, which is a flexible and fact-specific inquiry. Courts retain continuing authority to adjust parenting time orders when appropriate. Procedurally, you will use the state’s forms and respond within required timelines if you are served. See the statute and state forms guidance for details.
