To ask a court to either increase or decrease a child support obligation, you must prove to the court that a substantial change in circumstances has occurred. For example, if you were paying child support and your child moves in with you, you have the right to ask the court to enter an order directing the other parent to pay child support to you. Voluntarily quitting your job, or voluntarily attaining a lower paying job, is not a basis to ask the court to change your child support obligation.
