A process server's affidavit establishes, prima facie, the method of service, and gives rise to a presumption of proper service. A defendant's sworn statement of specific facts to rebut the statements in the affidavit of service necessitates an evidentiary hearing. However, no hearing is required where the defendant fails to swear to specific facts that rebut the statements in the affidavit of service.
