The notice must describe the nature of the controversy and the remedy sought.(2) Unless a person interposes an objection as to lack or insufficiency of notice under RCW 7.04A.150(3) not later than the commencement of the arbitration hearing, the person's appearance at the hearing waives any objection to lack of or insufficiency of notice.(3) A claim sought to be arbitrated is subject to the same limitations of time for the commencement of actions as if the claim had been asserted in a court.Amended by 2013 c 92,§ 1, eff. 7/28/2013.
