If you are suing someone, you must pay a filing fee and a service fee. Court costs are county specific. The Cobb County Sheriff’s Department must serve the Complaint and Summons. (Example: sue one Defendant - you pay one filing fee and one service fee; two Defendants - you pay one filing fee and two service fees, etc.). At the Judge's discretion, if you win the case, the defendant typically reimburses the court costs.
Filing fees are set forth by the Georgia State Legislative body and are subject to change.
