You receive a telephone call from an existing client who tells you that she is in the process of making a new will with another firm of solicitors. She tells you that she, therefore, wishes you to destroy the most recent will that your firm holds. You check your firm's storage and note that you hold a will dated last year and another dated three years ago. You confirm with the woman that she wishes for you to destroy the most recent will and, on her confirmation, you tear the will in half whilst she remains on the phone . A week later , the woman's daughter telephones you to say that her mother has passed away. She had seen and approved a copy of the new will she had been making with the other firm and was due to execute it tomorrow.How should the distribution of the woman's estate be determined?
