I concur with the court’s conclusion that the plaintiffs have not demonstrated that the provision in the Commercial Provider Administration Manual requiring them to be responsible for one-half of the fees and expenses directly related to conducting the arbitration renders arbitrating
their claims prohibitively expensive. The plaintiffs have the burden of proof on this point, Green Tree Fin. Corp. - Ala. v. Randolph, 531 U.S. 79, 92, 121 S. Ct. 513, 522 (2000), and thus they must demonstrate that it will be prohibitively expensive for them to pursue their claims in the arbitral
forum.
The plaintiffs’ claims for relief in this case go far beyond disputes over specific charges to particular patients. They have presented no evidence 1 that it will be more expensive to arbitrate their claims than it would be to litigate them. See Bradford v. Rockwell Semiconductor Sys., Inc., 238 F.3d 549, 556 (4th Cir. 2001); In re Currency Conversion Fee Antitrust Litig., 265 F. Supp.2d 385, 411 (S.D.N.Y. 2003). In the absence of this sort of evidence, the trial court properly declined to invalidate the arbitration provision.
