Illinois Statutes Chapter 725. Criminal Procedure § 5/114-10. Motion to Produce Confession

(a) On motion of a defendant in any criminal case made prior to trial the court shall order the State to furnish the defendant with a copy of any written confession made to any law enforcement officer of this State or any other State and a list of the witnesses to its making and acknowledgment. If the defendant has made an oral confession a list of the witnesses to its making shall be furnished.

(b) The list of witnesses may upon notice and motion be amended by the State prior to trial.

(c) No such confession shall be received in evidence which has not been furnished in compliance with subsection (a) of this Section unless the court is satisfied that the prosecutor was unaware of the existence of such confession prior to trial and that he could not have become aware of such in the exercise of due diligence.
