A will may dispose of property by reference to acts and events that have significance apart from their effect upon the dispositions made by the will, whether they occur before or after the execution of the will or before or after the testator's death. The execution or revocation of a will of another person is such an event.   [PL 2017, c. 402, Pt. A, §2 (NEW); PL 2019, c. 417, Pt. B, §14 (AFF).]
