(2) if the claim is allowed but disapproved, the claimant shall pay the costs;
(3) if the claim is rejected but established by suit, the estate shall pay the costs;
(4) if the claim is rejected and not established by suit, the claimant shall pay the costs, except as provided by Section 355.052; and
