In Ruff v. Ruff, a beneficiary of a trust sued a former trustee, and that dispute was sent to arbitration. No. 05-18-00326-CV, 2020 Tex. App. LEXIS 6344 (Tex. App.—Dallas August 11, 2020, no pet. history). After the arbitration ruled for the beneficiary, awarding her over $49 million, the former trustee appealed arguing that the dispute should not have been sent to arbitration.
