Defendant moved to set aside a default judgment because he was not properly served with the summons and complaint. The plaintiff had mailed the summons and complaint to the address the defendant had vacated about eight months before. Even though the U.S. Postal Service was forwarding the defendant’s mail to his new address and his wife signed a certified mail receipt for the summons and complaint, the Court held that service did not comply with Rule 7004(b). That rule requires that notice be sent to “the individual’s dwelling house or usual place of abode or to the place where the individual regularly conducts a business or profession,” which was not accomplished in this case. The Court also held that Rule 7004(b) requires that a plaintiff make a reasonable inquiry to determine the defendant’s dwelling house or usual place of abode, which the plaintiff did not do. Because proper service of process is necessary to obtain personal jurisdiction over a defendant, and a default judgment obtained without personal jurisdiction is void, the Court granted the defendant’s motion and set aside the default judgment under Rule 60(b)(4).
