What defines a holographic will?

A holographic will is defined as a handwritten will that is created solely by the testator. The essential characteristic of a holographic will lies in the fact that it must be in the testator's handwriting without the need for formalities such as witnessing or notarization, which are typically required for other types of wills. This format allows individuals to express their final intentions more freely, particularly in situations where they might not have immediate access to legal resources. It is crucial that the testator's handwriting is evident and that their intent to create a will is clear within the document. The other options do not accurately describe a holographic will, as they involve formalities or requirements that do not apply to this type of will.
