In Ferguson Enterprises, Inc. v. H. Webb Enterprises, Inc., 2000 OK 78, 13 P.3d 480, the Oklahoma Supreme Court held that a trial court abused its discretion when it refused to vacate a default judgment, entered after service of process was sent by certified mail but "refused" by a person who was not authorized to receive the mail. The Court found that, because the judgment roll did not reflect that the defendant was personally served or that the statutory procedure for service by certified mail was followed, the trial court lacked in personam jurisdiction over the defendant and the judgment should have been vacated.
