Courts and registers

Unless an order or judgment is entered in open court in the presence of the parties or their counsel, the register shall immediately upon the entry of an order or judgment serve a notice of the order including the terms of any order of custody, support or alimony by mail in the manner provided for in Rule 5 upon each party and shall make a note in the docket of the mailing. Such mailing is sufficient notice for all purposes for which notice of the entry of an order is required by these rules; but any party may in addition serve a notice of such entry in the manner provided in Rule 5 for the service of papers. Lack of notice of the entry by the register does not affect the time to appeal or relieve or authorize the court to relieve a party for failure to appeal within the time allowed, except as permitted in Rule 4 of the Massachusetts Rules of Appellate Procedure .
