Larry and Susan Deal, appellees-paternal grandparents of the child G. D., filed a petition for grandparents’s visitation rights against Tina Marie Oglesby, appellant-maternal grandmother of G. D., and Summer Nicole Thornburg, appellant-mother of G. D. Oglesby and Thornburg sought to have the petition dismissed for lack of personal jurisdiction and insufficient service of process, or in the alternative, to have the case transferred on the ground of improper venue. The trial court denied the motion, but granted a certificate of immediate review. We granted Appellants’s application for interlocutory review under Spivey v. Hembree , 268 Ga. App. 485, 486 n.1 602 SE2d 246 2004, and this appeal ensued. In two enumerations of error, Oglesby and Thornburg assert that the trial court erred in finding that Thornburg was subject to personal jurisdiction and properly served with process, and that venue was proper with respect to Oglesby. This Court finds that service was not effective as to Thornburg and that venue was improper as to Oglesby, and accordingly, we reverse. A preliminary hearing over defenses of lack of jurisdiction over the person or subject matter and improper venue whether made in a pleading or by motion may be heard and determined before trial on the application of any party. At such hearing factual issues shall be determined by the trial court. Factual determinations of the trier of fact will be reversed only where the evidence demands a contrary finding, and when the trial judge conducts a hearing on a motion to dismiss or transfer for improper venue, his findings, as a trier of fact, are tested by the any evidence rule.

Similarly, we will not disturb the trial court’s factual findings regarding the sufficiency of service if there is evidence to support them. Hardin Constr. Group, Inc. v. Fuller Enterprises, Inc. , 233 Ga. App. 717, 721-722 2 505 SE2d 755 1998. The evidence of record shows that G. D. was born on February 10, 2010, and has resided with Oglesby since that time. Until approximately May 2010, Oglesby resided at a modular home located at 129 Godley Road, Bloomingdale, Georgia.1 In May 2010, she and her husband moved to a new home that was located on the same road as the modular home, at 109 Godley Road, Bloomingdale, Georgia. Although on the same road, the homes were in different counties. The modular home was located in Effingham County; the new home was located in Chatham County although only about 200 yards from the Effingham County line. On September 22, 2010, Oglesby completed a petition for temporary letters of guardianship of G. D., which she filed in the probate court of Effingham County; she was appointed as G. D.’s temporary guardian on the same day.
On October 18, 2010, the Deals filed a petition for grandparents’s visitation rights in the Superior Court of Effingham County.2 The evidence shows that Oglesby was personally served with this action at 129 Godley Road in Effingham County. Although the evidence reflects that Thornburg moved to Arizona on October 7, 2010, the sheriff deputy purported to serve Thornburg by leaving the summons with Oglesby at 129 Godley Road.3
