What is a key function of a holographic will?

A holographic will is characterized primarily by being entirely written, dated, and signed by the testator in their own handwriting. This personal touch ensures that the will is a reflection of the testator's own thoughts and intentions regarding the distribution of their estate. The handwriting element serves as a crucial piece of evidence for the testator's intent, as it is harder to dispute the authenticity of a document that is solely written by the individual in question.

In contrast, a holographic will typically does not require any witnesses or notarization to be considered valid in many jurisdictions, which differentiates it from the other options that pertain to more formal will structures. This attribute allows individuals to create a will quickly without needing to engage legal formalities, often in situations where time is of the essence or where the testator may not have immediate access to legal assistance.

The other options either discuss formalities that do not apply to the nature of holographic wills or address aspects such as tax benefits and complexities that are not inherent to the fundamental function of a holographic will. Thus, the correct answer emphasizes the unique handwritten aspect of holographic wills, which is central to their validity and recognition in legal terms.
