No service need be made on parties against whom a default has been entered, except that pleadings asserting new or additional claims against them shall be served in the manner provided for service of summons. When service is required or permitted to be made upon a party represented by an attorney, service shall be made upon the attorney unless service upon the party is ordered by the court. Service on the attorney or party shall be made by delivering a copy or mailing it to the attorney or the party at the last known address or, if no address is known, by leaving it with the clerk of the court. Service by mail shall be complete upon mailing. When service is made by facsimile, a copy shall also be served by any other method permitted by this rule.
Facsimile service occurs when transmission is complete.
In actions when the parties are unusually numerous, the court may regulate the service contemplated by these rules on motion or on its initiative in such manner as may be found to be just and reasonable. All original papers shall be filed with the court either before service or immediately thereafter. If the original of any bond or other paper is not placed in the court file, a certified copy shall be so placed by the clerk. The filing of papers with the court as required by these rules shall be made by filing them with the clerk, except that the judge may permit the papers to be filed with the judge, in which event the judge shall note the filing date before him or her on the papers and transmit them to the clerk. The date of filing is that shown on the face of the paper by the judge's notation or the clerk's time stamp, whichever is earlier.
