In Arizona, what is the legal term for a will that is not witnessed but still valid?

A will that is not witnessed but is still considered valid in Arizona is referred to as a holographic will. This type of will is written entirely in the handwriting of the testator, and it does not require witnesses to be legally valid. Arizona recognizes holographic wills, provided the signature of the testator is present, indicating their intention to create a will.

The other terms listed have distinct meanings and functions. A testamentary will typically refers to a will executed in accordance with formal requirements, including witness signatures, which distinguishes it from holographic wills. A codicil is an amendment or addition to an existing will, intended to change or clarify its provisions, and does not stand alone as a will. A living will, on the other hand, is a legal document that outlines an individual's wishes regarding medical treatment in the event they become incapacitated, thus serving a completely different purpose from a traditional will.
