Question: Service of Process. Dr. Kevin Bardwell owns Northfield Urgent Care, LLC, a Minnesota medical clinic. Northfield ordered flu vaccine from Clint Pharmaceuticals, a licensed distributer of flu vaccine located in Tennessee. The parties signed a credit agreement that specified that any disputes would be litigated in the Tennessee state courts. When Northfield failed to pay what it owed for the vaccine, Clint Pharmaceuticals filed a lawsuit in Tennessee and served process on the clinic via registered mail to Dr. Bardwell, the registered agent of Northfield. Bardwell's wife, who worked as a receptionist at the clinic and handled inquiries on the clinic's Facebook site, signed for the letter. Bardwell did not appear on the trial date, however, and the Tennessee court entered a default judgment against Northfield.

When Clint Pharmaceuticals attempted to collect on the judgment in Minnesota, Bardwell claimed that the judgment was unenforceable. He asserted that he had not been properly served because his wife was not a registered agent. Should the Minnesota court invalidate the Tennessee judgment? Was service of process proper when it was mailed to the defendant medical clinic and the wife of the physician who owned the clinic opened the letter? Explain. [Clint Pharmaceuticals v. Northfield Urgent Care, LLC, 2012 WL 3792546 (Minn.App. 2012).]
