Or authors, or musicians, or anyone who has copyrighted material. If this is you, then you definitely want to think about having a valid, up-to-date will in place to protect who has the right to use your copyrighted work after your death. Otherwise, you are leaving it up to chance. Think of Sylvia Plath: she did not update her will after her separation, and her former husband and sister-in-law ended up in charge of her written works after her death – likely not the result she wanted. If you own a copyright over anything, you should get your will done now.
