(See ORS 114.150 for change of phraseology.) In support of her asserted right of exoneration the plaintiff cites the following Oregon decisions: Marshall v. Middleton, 100 Or. 247, 191 P. 886, 196 P. 830; Estate of Hodgkin, 110 Or. 381, 221 P. 169, 223 P. 738; Ladd Bush Trust Co. v. Kurtz, 169 Or. 225, 127 P.2d 732. The defendant seeks to distinguish the cases cited on the ground that the statute deals only with encumbrances created after execution of a will. He points out that the encumbrances in all three of the cases cited were created prior to the execution of the will.
