A party to the arbitration has a right to be represented by an attorney at any proceeding or hearing in arbitration, but this right may be waived. A waiver of this right may be revoked, but if revoked, the other party is entitled to a reasonable continuance for the purpose of obtaining counsel.
The arbitration may proceed in the absence of any party who, after due notice, fails to be present and to obtain a continuance. An award must not be based solely on the absence of a party. In the event of a default by defendant, the arbitrator must require the plaintiff to submit such evidence as may be appropriate for the making of an award.
