It is now much more common in Arizona for children to have parents who are no longer together. This could because the parents divorced or were never married in the first place. However, one thing that has always been true is that there are many expenses that parents must pay to support their children. This is true whether the parents are together or not. The difference is that when the parents are separated, there is generally a child support order to govern how the parents split the children's costs.
These orders are based on the child support guidelines in Arizona. These may seem like fairly rigid rules at first glance, but they can be very complicated matters. Determining a person's income is not always straightforward. Also, certain portions of a person's income may be excluded, pursuant to the guidelines, and disputes over a person's true income can arise.
