Except when the child is in detention, the court may permit a written plea of not guilty or a plea of not guilty on the record to be entered by child's counsel without the personal appearance of the child, child's parent(s), legal guardian or legal custodian or their counsel. The child's counsel shall immediately furnish a copy of the written plea of not guilty to the prosecuting attorney.
Minn. R. Juv. P. 8.03
