The right to object shall be deemed waived unless the objection is in writing, filed with the court, and served upon all other parties and the county attorney within three days after being informed that the matter is to be heard by a referee. Upon the filing of an objection, a judge shall hear any motion and shall preside at all further motions and proceedings involving the matter.
