You can file a Petition to Modify Child Support if there has been a significant change of circumstances, even if the Order was adjusted within the last two years. This process is a bit more complex and longer than the Motion to Adjust, but it is available to address things beyond a typical increase in the parents’ income.
Note: The remarriage of a parent does not automatically affect child support; the new spouse does not have an obligation to support the child. The income of a new spouse/partner or other adults in the household may be a basis for a deviation from the usual calculation of child support; however, that income by itself, is not a sufficient reason for a deviation. (There are several “deviation standards” that the court may consider in setting support at an amount other than the standard calculation.)
