Irving was a lawyer who prepared income tax returns for Maroevich. Irving agreed to draft a will for Maroevich, leaving all of the property to Maroevich’s sister, Biakanja. When Maroevich died, the probate court refused to accept the will because Irving had failed to have the signatures properly witnessed. As a result, Biakanja inherited only one-eighth of the estate. She sued Irving, who defended by saying that he had no duty of due care to Biakanja because all his dealings were with Maroevich and none were with her. Do you agree?
