Except as otherwise provided in these Rules, every order required by its terms to be served, every pleading subsequent to the original complaint unless the Court otherwise orders because of numerous defendants, every paper relating to discovery required to be served upon a party unless the Court otherwise orders, every written motion other than one which may be heard ex parte, and every written notice, appearance, demand, offer of judgment, designation of record on appeal, and similar paper shall be served upon each of the parties. No service need be made on parties in default for failure to appear except that pleadings asserting new or additional claims for relief against them shall be served upon them in the manner provided for service of summons in Rule 4.
An attorney may withdraw the attorney’s appearance without obtaining the court’s permission when the attorney is attorney for the plaintiff on a judgment entered on a warrant of attorney, or where such withdrawal will leave a member of the Delaware Bar appearing as attorney or record for the party. Otherwise, no appearance shall be withdrawn except on order of the Court.
In certiorari proceedings, the defendant in error shall appear within 20 days after service of the citation upon the defendant, or if no service is effected, then within 40 days after the date of the citation.
