Child Support: Summaries of State Laws

Nearly every aspect of family law is governed at the state level, which means the procedures and rules for determining child support payments differ by state. It can all get quite confusing, so it helps to get a handle on the rules and limitations of your state before negotiating with your child's other parent or guardian. In Arizona, for example, the court may not order parents to pay for college after their financial obligation ends when the child is 18. Kentucky law, meanwhile, allows courts to order payment of college tuition (on a case-by-case basis).

The following state law summaries will help you understand the basic child support guidelines of your state.

Alabama. Child support is determined under the Alabama Child Support Guidelines, unless the Court finds grounds to deviate from the guidelines. In Alabama, the Department of Human Resources is responsible for enforcing child support obligations. The court retains jurisdiction to modify child support, up or down, until the children reach the age of 19.

California. An explicit link between custody and child support is made by the provision that a court may order financial compensation to one parent for those periods of time the other parent fails to assume care taking responsibility. There may be additional financial compensation awarded to a parent who has been repeatedly thwarted by the other parent in attempts to exercise custody/visitation.
