(1) A familial relationship within the third degree exists between the umpire and a party or a representative of a party;
(2) The umpire has previously represented a party in a professional capacity in the same claim or matter involving the same property;
(3) The umpire has represented another person in a professional capacity on the same or a substantially related matter that includes the claim, the same property or an adjacent property, and the other person’s interests are materially adverse to the interests of a party; or
(4) The umpire has worked as an employer or employee of a party within the preceding 5 years.
