Yes, a court can modify or terminate grandparent visitation whenever doing so serves the child’s best interests. The statute also limits how frequently a new affidavit for visitation can be filed. A grandparent generally may not file more than once every two years unless the court finds good cause to allow another filing. Either party can request a hearing, and the court must hold one if it finds a hearing is in the child’s best interests. The motion is filed in the district where the child resides and must be served on the person with legal custody or parental responsibilities. These procedures and timelines are set out in Colorado’s grandparent visitation statute and the Judicial Branch’s self-help guidance.
