To adjust child support, parents need to show that there is a need to do so. Either parent can request for the child support to be adjusted, or to have the child support payments reevaluated and it is common for this to happen, especially when there are numerous employment changes or income changes for either parent. To adjust child support, the parent who wishes to make the judgment must proceed through the proper means, which may be a child support agency, or through the court system. A formal agreement will be made based on data about both individuals' income.
