Mealey's (September 13, 2020, 12:45 PM EDT) -- BISMARCK, N.D. — The North Dakota Supreme Court in an Aug. 31 divided opinion found that the equitable doctrine of partial invalidity is an applicable remedy under state law, affirming a lower court's decision invalidating portions of a will relating to the distribution of shares in a ranch that it found were the product of undue influence and treating the perpetrators of the undue influence as if they had not survived the decedent (In re Estate of Leo Grenz [Kelly Grenz v. Donavin Grenz, et al.], No. 20190363, N.D. Sup., 2020 N.D. LEXIS 190)....
