(a) Upon inclusion in the comptroller's registry of arbitrators, an individual who accepts an arbitration appointment shall conduct each arbitration proceeding pursuant to the terms of Tax Code, Chapter 41A, and this subchapter, and §9.804 of this title, as applicable; and for a fee that is not more than the applicable amount stated in the fee schedule set out in subsection (d) of this section.     
      (b) Each arbitrator included in the comptroller's registry is required to notify the comptroller online through the comptroller's online arbitration system when it is generally available, or in writing of any changes in contact information (including address, phone number, email address, website), and any material change in the information provided in his or her application or in his or her qualifications or eligibility for appointment within ten (10) calendar days of the change. A material change includes, but is not limited to a change in county of residence, loss of required licensure, incapacity, ineligibility or other condition that would prevent the person from lawfully and professionally performing arbitration duties.     
      (c) Violations of subsection (a) of this section or failure of the arbitrator to report a material change under subsection (b) of this section may result in the immediate removal of the arbitrator from the current registry upon its discovery and the denial of future applications for inclusion in the registry. An arbitrator's failure to report a material change as required by this section shall not affect the determinations and awards made by the arbitrator during the period that the arbitrator is listed in the registry.     
      (d) The arbitrator's fee shall not exceed:      
        (1) $400 if the property qualifies as the owner's residence homestead under Tax Code, §11.13, and the appraised or market value is $500,000 or less as determined by the ARB order;
