Okla. Stat. tit. 85A, § 85A-319: Record of the award

A. An arbitrator shall make a record of the award. The award

may contain the evidence and conclusion upon which the award was

based unless the agreement of the parties specifies the type of

award to be issued. The record shall be signed or otherwise

authenticated by any arbitrator who concurs with the award. The

arbitrator or the arbitration organization shall give notice of the

award, including a copy of the award, to each party to the

arbitration proceeding.

B. An award shall be made within the time specified by the

agreement to arbitrate or, if not specified therein, within the time

ordered by the Commission. The Commission may extend or the parties

to the arbitration proceeding may agree in a record to extend the

time. The Commission or the parties may do so within or after the

time specified or ordered. A party waives any objection that an

award was not timely made unless the party gives notice of the

objection to the arbitrator before receiving notice of the award.
