In Dugenske v. Dugenske, 80 Wis. 2d 64, 69, 257 N.W.2d 865 (1977), the supreme court held that the trial court did not err by finding that misfiling of legal documents because of confusion caused by the attorney moving his office did not constitute excusable neglect. See id. Nonetheless, the determination whether to vacate a default judgment is within the sound discretion of the trial court, see id. at 68.
