Louise Kane executed a will that left her entire estate to her grandson. When her grandson died, Louise 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 Louise. After Louise 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 Louise had been mentally competent when she executed her will. Does undue influence appear likely based on these facts? Why or why not?
