Torts — Nursing homes — Arbitration — Trial court did not err in compelling arbitration of claims brought on behalf of nursing home resident based upon injuries sustained before execution of arbitration agreement — Agreement required arbitration of any “dispute or controversy” which may arise between the parties, and “dispute or controversy” between resident and nursing home did not arise until she filed suit — Agreement was not procedurally unconscionable — Attorney’s fees provision requiring each party to bear own attorney’s fees and costs unless otherwise specifically awarded by arbitrator under state or federal law did not violate public policy
