A partner of your firm brings you the will of a client who has died. He mentions that the will had been left in storage for many years with a paperclip on the front page. The paperclip has aged and started to rust, leaving a dirty brown mark when it is removed. The partner tells you that he found no other documents in storage save for the will but asks you to check whether the client ever came to the firm for any other purpose.What do you think is the partner's primary concern?
