FEDERAL RULES OF CIVIL PROCEDURE
II. Commencement of Action; Service of Process, Pleadings, Motions and Orders
Rule 5 Service and Filing of Pleadings and Other Papers
(a) Service: When Required. 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.
In an action begun by seizure of property, in which no person need be or is named as defendant, any service required to be made prior to the filing of an answer, claim, or appearance shall be made upon the person having custody or possession of the property at the time of its seizure.
(b) Same: How Made. Whenever under these rules service is required or permitted to be made upon a party represented by an attorney the service shall be made upon the attorney unless service upon the party is ordered by the court. Service upon the attorney or upon a party shall be made by delivering a copy to the attorney or party or by mailing it to the attorney or party at the attorney's or party's last known address or, if no address is known, by leaving it with the clerk of the court. Delivery of a copy within this rule means: handing it to the attorney or to the party; or leaving it at the attorney's or party's office with a clerk or other person in charge thereof; or, if there is no one in charge, leaving it in a conspicuous place therein; or, if the office is closed or the person to be served has no office, leaving it at the person's dwelling house or usual place of abode with some person of suitable age and discretion then residing therein. Service by mail is complete upon mailing.
(c) Same: Numerous Defendants. In any action in which there are unusually large numbers of defendants, the court, upon motion or of its own initiative, may order that service of the pleadings of the defendants and replies thereto need not be made as between the defendants and that any cross-claim, counterclaim, or matter constituting an avoidance or affirmative defense contained therein shall be deemed to be denied or avoided by all other parties and that the filing of any such pleading and service thereof upon the plaintiff constitutes due notice of it to the parties. A copy of every such order shall be served upon the parties in such manner and form as the court directs.
(d) Filing; Certificate of Service. All papers after the complaint required to be served upon a party, together with a certificate of service, shall be filed with the court within a reasonable time after service, but the court may on motion of a party or on its own initiative order that depositions upon oral examination and interrogatories, requests for documents, requests for admission, and answers and responses thereto not be filed unless on order of the court or for use in the proceeding.
(e) Filing With the Court Defined. The filing of papers with the court as required by these rules shall be made by filing them with the clerk of the court, except that the judge may permit the papers to be filed with the judge, in which event the judge shall note thereon the filing date and forthwith transmit them to the office of the clerk. A court may by local rule permit papers to be filed, signed, or verified by electronic means that are consistent with technical standards, if any, that the Judicial Conference of the United States establishes. A paper filed by electronic means in compliance with a local rule constitutes a written paper for the purpose of applying these rules. The clerk shall not refuse to accept for filing any paper presented for that purpose solely because it is not presented in proper form as required by these rules or any local rules or practices.
