Susie Walker executed a will that left her entire estate to her grandson. When her grandson died, Susie executed a new will that named her great- grandson as her sole beneficiary and specifically disinherited her son, Tommy. At the time, Tommy’s ex-wife was living with Susie. After Susie died, Tommy filed a suit, claiming that her will was the product of undue influence on the part of his ex-wife. Several witnesses testified that Susie had been mentally competent when she executed her will. Does undue influence appear likely based on these facts? Why or why not?
