(a) An application for a judgment by default, irrespective of the amount of the proposed judgment, must be made upon affidavit unless the court specifically requests the presentation of oral testimony. Supporting affidavits must be made on personal knowledge, not by the attorney representing the plaintiff; set forth such facts as would be admissible in evidence; show affirmatively that the affiant is competent to testify to the matters stated therein; and avoid mere general conclusions or argument. An affidavit substantially defective in these respects may be stricken, wholly or in part, and the court may decline to consider the application for the default judgment.
(b) Unless written notice of the application is required or the prior consent of the court is obtained, a request for the entry of judgment by default under N.R.C.P. 55(b)(2) must be made without placing the matter on the motion calendar. The application, together with any supporting affidavits, must be left with the clerk who shall promptly deliver the same to the judge for consideration in chambers.
