The short answer is no. This is not precisely a will contest, but contesting the distribution terms of the will. Texas Estates Code section 201.058(d) prevents a “beneficiary of a life insurance policy or contract who is convicted and sentenced as a principal or accomplice in willfully bringing about the death of the insured”…from inheriting due to wrongful conduct. Courts would impose a constructive trust on the wrongdoer in favor of different beneficiaries. See Bounds v. Caudle, 560 S.W.2d (Tex. 1977), appeal after remand, 611 S.W.2d 685 (Tex. Civ. App.–Corpus Christi, writ ref’d n.r.e.). In other words, the murderer inherits nothing.
