De. R. Crim. P. Super. Ct. 30
At the close of the evidence or at such earlier time during the trial as the court reasonably directs, any party may file written requests that the court instruct the jury on the law as set forth in the requests. At the same time copies of such requests shall be furnished to all parties. The court shall inform counsel of its proposed action upon the requests prior to their arguments to the jury. The court may instruct the jury before or after the arguments are completed or at both times. All instructions shall be given by the court orally. In capital cases the court shall, and in other cases the court may, give the jury a copy of the instructions for use during deliberations. No party may assign as error any portion of the charge or omission therefrom unless that party objects thereto before or at a time set by the court immediately after the jury retires to consider its verdict, stating distinctly the matter to which that party objects and the grounds of the objection. Opportunity shall be given to make the objection out of the hearing of the jury and, on request of any party, out of the presence of the jury.
