Ga. Code § 44-6-160
When two or more persons are common owners of lands and tenements, whether by descent, purchase, or otherwise, and no provision is made, by will or otherwise, as to how such lands and tenements shall be divided, any one of such common owners may apply by petition to the superior court of the county in which such lands and tenements are located for a writ of partition which shall set forth plainly and distinctly the facts and circumstances of the case, shall describe the premises to be partitioned, and shall define the share and interest of each of the parties therein. When the lands in question constitute a single tract situated in more than one county, the application may be made to the superior court of any of such counties.
