The answer depends on the facts and circumstances of your particular case. If the child support payments are made through a court collection system, you may have an automatic right to review the amount after a set period of time. If the child support payments are made directly to the spouse, you must prove your case based on the standards set forth in case law if the stipulation was signed prior to July 15, 2010. If the stipulation was executed after July 15, 2010 or if the child support award was ordered by the judge after a trial on the issue, you may seek an upward or downward modification in child support if the income of either parent changed by more than 15% or if more than three years elapsed since the date of the order or agreement.
