(a) The award shall be in writing and signed by the arbitrators joining in the award. The arbitrators shall deliver a copy to each party personally or by registered or certified mail, return receipt requested, or as provided in the agreement.
(b) An award shall be made within the time fixed therefor by the agreement or, if not so fixed, within such time as the Court orders on complaint or application of a party in an existing case. The parties may extend the time in writing either before or after the expiration thereof. A party waives the objection that an award was not made within the time required unless the party notifies the arbitrators of such objection prior to the delivery of the award. The arbitrators shall deliver a copy of the award to each party in the manner provided in the agreement, or if no provision is so made, personally or by registered or certified mail, return receipt requested.
