Which type of will does not require witnessing?

A holographic will is a type of will that does not require witnesses to be valid. For a holographic will, the testator (the person making the will) must write the entire document in their own handwriting and sign it. This form of will is typically used for reasons of simplicity or when a person does not have immediate access to the formalities of drafting a will with witnesses.

Nuncupative wills, which are oral wills declared in the presence of witnesses, are also considered valid under certain circumstances but vary significantly in their legal acceptance depending on the jurisdiction. Formal wills typically require the presence of witnesses to validate the document, ensuring that the testator's intent is clearly represented and safeguarded.

The distinction between these kinds of wills is critical as it highlights the specific legal requirements that govern will creation, particularly in Arizona, where laws may further dictate how and when these wills are recognized in probate court.
