A child becomes legally available for adoption only after specific consents or court orders are in place. Colorado law lists qualifying paths that include termination of parental rights by court order, voluntary relinquishment by a parent, or written consent from a court-appointed guardian if the parents are deceased. The statute also addresses additional circumstances that create legal availability. These safeguards ensure that the child’s legal status is clear before an adoption proceeds. Courts review filings to confirm that one of these statutory routes has been satisfied. The availability requirement is codified in the Colorado Children’s Code.
