Like most states, Georgia uses a formula that takes into account the income of both parents and divides the cost of child-raising to determine a so-called ‘guideline’ amount. For reasons of consistency and objectivity, this is the amount that is presumed to be fair for the non-custodial parent to pay to the custodial parent. However, the law makes some room for adjustment of this amount if either parent can show evidence rebutting this presumption. Georgia Code Section 19-6-15 covers the calculation process and also describes how deviations from the guidelines work, and gives examples of specific deviations that might be allowable. While the list is not exhaustive, it gives one an idea of the kind of evidence that may be necessary to rebut the presumptive guideline amount and get a different amount ordered. First among these specific deviations are extremes of income amongst the parents. The guidelines were created for the average situation and very high or very low incomes may need some adjustment. The cost of health or life insurance policies that benefit the child may also be used as a deviation. A factfinder may deviate from the guidelines to allow for the receipt of a child tax credit, or the travel expenses of a parent following a court-ordered visitation schedule. Actual alimony paid may be the basis for a deviation. If the non-custodial parent pays the mortgage on the children’s residence, or provides it to the custodial parent at no cost, deviation may be allowed. A court may also deviate from guidelines if the child is in the foster care system and the non-custodial parent is attempting to get the children back by setting up a household according to a permanency plan. Extraordinary expenses for the child, such as abnormal medical or educational expenses may be a basis for deviation, as may be an unusual parenting time arrangement. Of course, there may also be non-specific reasons not included above that can create the basis for a guideline deviation. The main thing to remember is the court or jury must normally make written findings supporting the deviation, and must always do so with the best interest of the child in mind. Deviations are not easy to procure, and if you have questions about child support in Georgia, you may wish to consider consulting an experienced family attorney.
