Georgia Code Title 36. Local Government § 36-3-20

When the boundary line between two or more counties is in dispute and the grand jury of either county presents that the boundary line needs to be marked out and defined, it shall be the duty of the clerk of the superior court in the county where the presentments were made to certify the presentments to the Governor. The Governor shall appoint some suitable and competent land surveyor, who shall not reside in either county, to survey, mark out, and define the boundary line in dispute and to return the survey with plat to the Secretary of State's office to be recorded in a book to be kept for that purpose.
