My son does pay child support and carries insurance on his daughter. Her mother is wanting her husband to adopt her. My son has not been able to see his daughter in years, because the mother would not let him, and he did not know where she lived or how to get a hold of his daughter. He is very much wanting a father/daughter relationship with her. In the state of Colorado, can he stop it? I the grandmother would like to have visitation too along with him. If you did not do what the mother wanted you to do, you did not get to see her or talk to her. I called on my grand daughter's b-day and her mother hung up on my( this was two years ago)
