Ga. Code § 18-3-32
When the plaintiff in attachment wishes to levy his attachment upon property in a different county from that in which the same is returnable, it shall be the duty of the judge issuing the attachment, upon the request of the plaintiff, his agent, or his attorney at law, to make out a copy or copies of the original attachment, bond, and affidavit and certify the same officially to be true copies. Upon delivery of the copies of the attachment, bond, and affidavit, as directed, to any officer of the county in which the property of the defendant is located, it shall be the duty of the officer forthwith to levy the attachment upon the property of the defendant located in that county and to return the attachment, with his actings and doings entered thereon, to the court to which the original attachment is returnable.
