In Ackers v. Comerica Bank & Trust, N.A., an income beneficiary sued a trustee for a declaration regarding the construction of a testamentary trust. No. 11-18-00352-CV, 2020 Tex. App. LEXIS 10442 (Tex. App.—Eastland December 31, 2020, no pet. history). The will provided that the income beneficiary was to receive the income from the corpus of the trust during his lifetime, and upon his death, the trust would terminate and the corpus of the trust would pass to the “then-living descendants” of the income beneficiary. The income beneficiary brought a declaratory judgment action seeking a determination that some of his descendants should be excluded at his death, and the trial court entered summary judgment that the relief sought was not ripe for consideration.
