The order of presentation at the fact-finding hearing must be as agreed by the parties or as determined by the fact finder. The fact finder is the judge of the relevancy of the evidence. All evidence must be taken in the presence of all parties, unless a party is absent in default or has waived its right to be present. Each documentary exhibit must be submitted to the fact finder and copies must be provided to the other parties. The exhibits must be retained by the fact finder until an agreement has been signed, after which they may be disposed of as agreed by the parties or as ordered by the fact finder.
