The 2008 case, JR Construction/Electric v. Ordner Construction, 669 S.E. 2d 224 (Ga. App. 2008), involved an out of state electrical subcontractor who sought to satisfy the licensing requirement by joint venturing with a local, licensed subcontractor. The Court found that this was inadequate because of the limited services performed by the licensed individual--he showed up, according to the evidence, only to provide the license. As a result, the Court invalidated the lien, and held that the subcontract was unenforceable. The subcontract was void because it violated public policy.
Based on this case, subcontractors lacking a proper license may be able to protect themselves by joint venturing, but only if the licensed individual observes and supervises the work.
