Child support generally may be changed or modified by filing a motion to modify and demonstrating to the court that the circumstances of the child or one or both parents have materially and substantially changed, or that some period of time (3 years, for example) has passed since the court’s last child support order. And if there has been a material and substantial change in the custody of the child—if, for example, the noncustodial parent who was paying child support has become the custodial parent—the court may change or eliminate the child support obligation based on the change in the custody arrangement.

In Georgia, child support orders can be modified if there has been a significant change in either the non-custodial or custodial parent's income or the needs of the child. A motion to modify child support must be filed, and the parent seeking the modification must demonstrate to the court that there has been a material and substantial change in circumstances since the last order was issued. This could include changes in income, job status, or the financial needs of the child. Additionally, Georgia law typically allows for a review of child support orders every two years without the need to show a change in circumstances. Furthermore, if there is a change in custody, where the noncustodial parent becomes the custodial parent, the court may revise or terminate the child support obligation to reflect the new custody arrangement. It is important for parents to note that any modification of child support is not automatic and must be approved by the court to take effect.
