O.C.G.A. § 18-3-10

No writ of attachment shall issue unless accompanied by a bond with good security, conditioned to pay the defendant all costs and damages that he may sustain in consequence of the issuance of the writ of attachment in the event that the amount claimed to be due was not due, that no lawful ground for issuance of the attachment existed, or that the property sought to be attached was not subject to attachment. The bond shall be in a sum equal to twice the amount claimed due in the plaintiffs application. The bond shall be presented to the clerk of the court where the application provided for in Code Section 18-3-9 is sought to be filed for approval by such clerk prior to filing of the writ of attachment.
