A holographic will is one that you have written yourself. They are generally handwritten, although some states may allow for a holographic will to be created on a typewriter or with word processing software. These kinds of wills are not allowed in some states, but other states permit this kind of informal will. In states that permit them, the laws relating to holographic wills can be very specific or restrictive. For example, California requires that you write all material provisions entirely by hand and that you must sign your holographic will. On occasion, a holographic will is better than no will at all. In cases where the holographic will creates an ambiguity or an unintended result, it may have been better to have no will at all.
