When you hear the words, "parental responsibilities," you probably have your own take on what they mean. You could consider the responsibility to be a good parent, to teach your child or to take them to activities. You may consider it paying for medical fees or going to work to put food on the table. Your definition can vary, but the definition by law refers to the rights and responsibilities of parents to care for their children.
When you go to court over child custody in Colorado, a judge will allocate your parental responsibilities. That essentially means that the judge is going to determine how much time a child spends with each parent. On top of that, the judge will decide which parent will get to make the decisions about the child's welfare. Decision-making responsibilities include things like determining your child's education, deciding which religion your child should be exposed to and allocating the right medical care to your child.
