Support Ratio = Non-custodial Parent Income / Combined Parental Income

Tips

• ✔The child support guidelines are revised by the Seoul Family Court every 2–3 years. Check the latest version for accurate calculations.
• ✔Parental agreement takes priority for child support. If agreement is not possible, you can file for a child support ruling at the family court. Agreements notarized as public deeds are enforceable.
• ✔As children grow, reasons for increasing or decreasing support may arise. You can petition for modifications due to rising education costs, medical expenses, or income changes.
• ✔The Child Support Enforcement Agency can assist with payment enforcement, collection, and sanctions for non-compliance.
