Margaret Delaney was a client of Joseph Plonsky, an attorney. In addition to being friends for many years, he had represented her in a number of transactions. One day, she went to see him and indicated that she would like to change her will to leave everything she owned to him. Plonsky drafted a will according to her specifications and it was properly executed. Several months later, Delaney died and the will was probated. Mrs. Delaney was survived by two nephews and two nieces, none of whom received anything under the will. They contested the validity of the will. Does the doctrine of undue influence apply to this case? Who is likely to win? Explain.
