(2) If the hearing has already been held, in the county where it was held; or

(3) In the county where any party resides or does business; or

(4) If there is no county as described in paragraph (1), (2), or (3) of this subsection, in any county.

(c)(1) A demand for arbitration shall be served on the other parties by registered or certified mail or statutory overnight delivery, return receipt requested.
