DILLARD, Judge.

Richard Lewis and Priscilla Lewis, individually and as parents of Richard L. Lewis III, sued the Hancock County School District and several of its employees, including George Cosby and James Robbins, in both their official and individual capacities, claiming that defendants' negligence caused the death of the Lewises' son. Following a defense motion, most of the defendants were dismissed on sovereign-immunity grounds. However, based on Cosby and Robbins's failure to file timely responsive pleadings, the trial court entered a default judgment against those two defendants in their individual capacities. Cosby and Robbins now appeal from the trial court's denial of their motion to set aside the default judgment, arguing that the judgment was a nullity because the court lacked both subject matter and personal jurisdiction, and alternatively, arguing that the court erred by not opening the default judgment on the grounds of excusable neglect and proper case. For the reasons set forth infra, we reverse the trial court's decision and remand the case for further proceedings consistent with this opinion.

The events underlying this appeal are unquestionably heart wrenching. In August 2006, Richard Lewis III, and a group of his fellow classmates from Hancock Central High School traveled to Atlanta to attend an ROTC competition. Cosby and Robbins, both of whom were employees of Hancock Central High School, accompanied the students as chaperones. Shortly after arriving at the group's hotel and assisting the students with checking into their rooms, Cosby, Robbins, and a few of the students allegedly left the hotel premises to get something to eat. And while Cosby and Robbins were away, Lewis and several other students decided to go swimming in the hotel's pool. Shortly after entering the swimming pool, Lewis appeared to be in great distress and began drowning. Lewis was quickly pulled from the swimming pool and emergency medical technicians were called immediately. Tragically, neither the EMTs nor the emergency-room physicians at the hospital where Lewis was transported were able to revive him.

Thereafter, Lewis's parents filed suit against the Hancock County School District and several of its employees but subsequently dismissed their lawsuit without prejudice. The Lewises then refiled their wrongful-death action against the same defendants, including Cosby and Robbins in both their official and individual capacities. And while the school district and the district superintendent filed timely answers to this complaint, Cosby and Robbins did not file their answers until well after the deadline for doing so, as a result of some confusion regarding whether they had been served.

All of the defendants, including Cosby and Robbins, thereafter filed a motion to dismiss the complaint, arguing, inter alia, that the Lewises' claims were barred by the doctrines of sovereign immunity and official immunity. Upon considering this motion, the trial court entered an order dismissing the claims against Cosby and Robbins in their official capacities but granting a default judgment against them in their personal capacities based on their failure to file timely answers.

Two days after the entry of the default judgment, Cosby and Robbins filed a motion to set aside the judgment entered against them in their individual capacities. In that motion, Cosby and Robbins argued that (1) the Lewises' claims were barred by the doctrines of sovereign immunity and official immunity, (2) the trial court lacked personal jurisdiction due to deficient service of process, and (3) the trial court should open the default on the grounds of excusable neglect and/or proper case under OCGA § 9-11-55(b). Following a hearing on the matter, the Lewises filed a motion to dismiss the school district and several of its employees, which the trial court granted. And then, the trial court issued another order, ruling that Cosby and Robbins were entitled to immunity in their official capacities but were not entitled to immunity in their individual capacities because of their failure to file timely answers. In that same order, the court also found that service of process was not deficient and that Cosby and Robbins had not shown that the default should be opened pursuant to OCGA § 9-11-55(b). Cosby and Robbins then sought and successfully obtained a certificate of immediate review from the trial court, and we granted their application for interlocutory appeal. This appeal follows.

1. Cosby and Robbins (hereinafter "appellants") contend that the trial court erred in failing to vacate the default judgment. Specifically, appellants argue that they are entitled to official immunity as employees of the school district, and therefore, the trial court lacked the subject matter jurisdiction to enter a default.

At the outset, we note that, absent an abuse of discretion, "we will not reverse a trial court's refusal to set aside a default judgment."1 Nevertheless, "(t)he standard of review for a question of law on appeal is de novo," during which "we owe no deference to the trial court's ruling and apply the `plain legal error' standard of review."2 With these guiding principles in mind, we will now address the substance of appellants' argument.

In considering appellants' claim of entitlement to official immunity from this lawsuit, we begin by noting that our Supreme Court has held that "[t]he doctrine of official immunity, also known as qualified immunity, offers public officers and employees limited protection from suit in their personal capacity."3 The doctrine of qualified immunity derives from a 1991 amendment to the Georgia Constitution, which provides in relevant part:

In expounding upon this doctrine, we have held that "qualified immunity mandates that a public employee is not immune from suit when he performs ministerial acts negligently or performs ministerial or discretionary acts with malice or an intent to injure; rather, he or she is immune from suit only for the negligent performance of discretionary acts."5 Importantly, our Supreme Court has similarly concluded that—consistent with the United States Supreme Court's opinion in Mitchell v. Forsyth6 — qualified immunity "is an entitlement not to stand trial rather than a mere defense to liability,"7 and as such, a trial court "must consider as a threshold issue whether the officer is entitled to qualified immunity from personal liability in a lawsuit for damages."8 Moreover, it is undisputed that the doctrines of sovereign immunity and official immunity are applicable to county-wide school districts and the employees of those districts.9

Notwithstanding the foregoing law, the trial court entered a default judgment against appellants in their individual capacities, finding that they were not entitled to the "defense" of official immunity. In so holding, the trial court erred. As noted supra, official immunity is not a mere defense but rather an entitlement not to be sued that must be addressed as a threshold matter before a lawsuit may proceed.10 Indeed, the plain meaning of the 1991 amendment to the Georgia Constitution regarding official immunity clearly supports this conclusion by providing that "[e]xcept as provided in this subparagraph, officers and employees of the state or its departments and agencies shall not be subject to suit or liability, and no judgment shall be entered against them, for the performance or nonperformance of their official functions. The provisions of this subparagraph shall not be waived."11 Furthermore, "merely naming a defendant individually in a complaint is not conclusive as to the capacity in which that defendant is sued."12 Instead, "the reason for the lawsuit is the determinative factor as to a defendant's capacity."13 And while appellants were sued in both their official and individual capacities, it is undisputed that the Lewises' wrongful-death suit arose from actions the appellants took in their official capacities as employees of the school.14 Thus, the trial court erred as a matter of law in finding that the entry of the default judgment barred the appellants from being able to assert that official immunity protected them from the Lewises' wrongful-death action.15

Accordingly, we reverse the trial court's order denying appellants' motion to set aside the default judgment and remand the case to the trial court for a threshold determination as to whether appellants' acts or omissions that allegedly led to Richard Lewis's death were ministerial or discretionary in nature. And while the Lewises argue on appeal that appellants' acts were indeed ministerial, we are unwilling to entertain this argument, given the complete lack of any evidence in the record on that particular issue. Additionally, even if such evidence were contained in the appellate record, the trial court is the more proper forum for any initial review of this evidence and analysis regarding this issue.

2. Appellants also contend that the trial court erred in failing to set aside the default judgment based on the lack of personal jurisdiction. Specifically, appellants argue that there is no order appointing a permanent process server in this case, and therefore, the Lewises' use of such a process server constituted a failure to perfect service. And because resolution of this enumeration of error in appellants' favor would negate the need for this case to be remanded, we now address the issue and hold that the trial court did not err in finding that service upon appellants was perfected.

In considering appellants' contention that the Lewises failed to perfect service, we begin by noting that the question of "[w]hether evidence is sufficient to overcome facts reflected in a return of service is a matter addressed to the discretion of the trial court."16 Indeed, a return of service is prima facie evidence of personal service,17 and it may only be set aside when the defendant presents evidence that is "the strongest of which the nature of the case will admit."18 Furthermore, factual disputes regarding service of process "are to be resolved by the trial court, and the court's findings will be upheld if there is any evidence to support them."19 Moreover, OCGA § 9-11-4(c) provides that "[p]rocess shall be served by the sheriff of the county where the action is brought or where the defendant is found, or by his deputy, or by the marshal or sheriff of the court, or by his deputy, or by any citizen of the United States specially appointed by the court for that purpose."20

And while it is undisputed that appellants were served with the summons and complaint in this matter, they nevertheless argue that service of process was deficient because the process server used by the Lewises had not been properly appointed by the Superior Court of Hancock County. Additionally, appellants argue that service was deficient because the process server filed sheriff's entries of service with the trial court instead of separate affidavits.21 In response, the Lewises assert that a 2003 court order appointing the process server in question as a permanent process server for the Superior Courts of the Ocmulgee Judicial Circuit—which includes Hancock County22 — authorized that process server to serve the complaint in this action. We agree.

Given the 2003 court order appointing the permanent process server, the entry of service, and the fact that appellants do not dispute that they were actually served with the complaint, we find that there was some evidence to support the trial court's ruling that the process server was authorized to serve appellants with the complaint in this action.23 Moreover, whether the permanent process server was authorized to file the sheriff's entries of service rather than his own affidavits as proof of service bears no weight in determining whether proper service was in fact made. As this Court has previously held,

Accordingly, the trial court did not err in finding that service of process was perfected in this matter.

3. In light of our holdings in Divisions 1 and 2, we need not address at this time appellants' remaining enumerations of error.

Judgment reversed and case remanded.
