Colorado uses the term “Parental Responsibility” for setting forth whether one parent or both parents have the responsibility to make major decisions for their child/children. Historically this was referred to as “Custody”. In Colorado, a parent’s gender does not create a presumption by law that he/she can make better decisions for the children and a parent’s gender does not determine where the child will primarily live. The Court will determine the decision making authority for a child based upon a number of factors including the parents’ ability to cooperate and make decisions jointly regarding the child/children.
