At any time prior to the J.C.A. trial (evidentiary hearing), the court, upon motion of the juvenile, the juveniles parent(s), or upon its own motion, may order one or more conferences to consider such matters as would promote a fair and expeditious trial. At the conclusion of the conference, the court shall file a memorandum of the matters agreed upon. No admission made by the juvenile or the juvenile's attorney at the conference shall be used against the juvenile unless the admissions are reduced to writing and signed by the juvenile and the juvenile's attorney.
Id. Juv. R. 12
