Del. R. Ch. Ct. 141
Where the order of reference specifies the time to begin taking testimony before the Master, and also the time for closing proofs, the Master shall have no power to extend the time beyond the day named in the order, but when a matter is referred to a Master to examine and report upon, and the order of reference does not specify any time to begin taking testimony or for closing proofs, the Master shall, as soon as practicable, assign a time and place to hear the parties, give reasonable notice to all persons interested, and proceed with all reasonable diligence in every such reference. Any party in interest shall be at liberty to apply to the Court for an order that the Master speed the proceedings and certify to the Court the reasons for any delay.
