Iowa Code § 518A.26: Arbitration.

No recovery on a policy or contract of insurance shall be defeated for failure of the insured to comply, after a loss occurs, with any arbitration or appraisement stipulation as to fixing the value of property. No arbitration shall take place except substantially where the property was situated at the time of loss. Contracts of insurance to indemnify against loss by hail to growing crops which stipulate for arbitration shall provide that the decision of the majority of the arbitrators shall be final only as to the arbitration.
