Georgia child support law covers the financial responsibility one parent owes to another when they do not live together. The state's laws apply whether parents were married, in a civil union, or never married. According to Georgia's Official Code Section 34-1-2, child support obligations generally continue until a child turns 18 years old, or until age 20 if the child remains in high school full-time and the parents agree.

The state uses specific formulas to calculate how much support one parent should pay. Georgia's Child Support Guidelines establish these calculations based on the parents' combined income. The formula considers both parents' gross income from all sources—including wages, salary, bonuses, rental income, and self-employment earnings. For example, if two parents have a combined income of $5,000 per month and one parent earns $3,500 while the other earns $1,500, the parent earning more typically pays a percentage of the difference based on the child's needs.
Georgia recognizes several types of child support situations. Primary physical custody means one parent has the child most of the time, while the other parent pays support. Shared custody arrangements may result in different calculations where both parents contribute based on their income and custody time. Joint custody does not automatically eliminate support obligations; instead, the court examines each parent's income and the time spent with each parent to determine appropriate payments.
The guide explains how Georgia courts determine child support amounts by examining:
Takeaway: Understanding Georgia's basic framework helps you see how child support amounts are determined and what factors the state considers. This knowledge prepares you to review any calculations or court orders affecting your situation.
Georgia uses what is called an "income shares model" to calculate child support. This means the state assumes both parents should contribute to their children's expenses based on how much money each parent earns. The calculation starts with each parent's gross monthly income. Gross income includes regular wages, self-employment income, overtime, bonuses, rental income, Social Security, unemployment benefits, pension payments, and certain other sources.

Once the state determines gross income for both parents, it applies standard deductions. As of recent years, Georgia allows a basic living expense deduction of about $1,650 per month for single-income households, though this amount may adjust yearly. After subtracting these deductions from gross income, the remaining amount is called "adjusted income." The state then determines what percentage of the combined adjusted income each parent should contribute to the children's support.
The percentages Georgia uses are based on the number of children:
For example, if parents have combined adjusted income of $4,000 monthly and two children, 25% of that income ($1,000) represents the total child support obligation. The parent with higher income pays their proportionate share. If one parent earns 70% of the combined income and the other earns 30%, the higher-earning parent would pay 70% of the $1,000 obligation, or $700 per month.
The guide also covers additional expenses beyond the basic calculation. These include:
Takeaway: The Georgia calculation method is straightforward once you understand the steps: determine gross income, apply deductions, apply the percentage for your number of children, and calculate each parent's share. You can estimate potential support amounts by gathering income documents and using these percentages.
Georgia law recognizes that family situations change. A parent's income may increase or decrease, custody arrangements may shift, health insurance coverage may change, or new children may be born. The state allows modification of child support orders when circumstances change substantially. A "substantial change in circumstances" typically means a change of at least $50 per month or at least 10% in either parent's adjusted gross income.

Parents can request modification through the Georgia courts. Either parent can file a petition for modification with the court that entered the original order, usually the Superior Court in the county where the child or the receiving parent lives. The requesting parent must show the substantial change in circumstances has occurred since the last order or at least three years have passed since the order was entered.
Common situations that lead to modification requests include:
The process requires filing documents with the court and typically attending a hearing where both parents present their income information and circumstances. The judge reviews the evidence and determines whether a modification is warranted. During this time, the parent paying support must continue making payments under the existing order unless the court temporarily suspends payments pending the hearing.
Georgia also has an automatic review provision. Every three years, the state can review child support orders even if neither parent requests it. This ensures that orders stay current with changing economic conditions. Courts may also review orders when a child turns a certain age or when other significant life events occur.
Takeaway: If your income or family situation changes notably, you may be able to request a modification. Keeping documentation of income changes and important events helps support your case when presenting the modified circumstances to the court.
When a parent fails to pay court-ordered child support, Georgia law provides several enforcement mechanisms. The state has strong enforcement procedures because child support is considered a legal obligation. If you are not receiving payments you are entitled to, the guide explains the options available to you.
