What does a testator who dies testate not require?

When a testator dies testate, it means that they have created a valid will that outlines how their assets should be distributed upon their death. In this case, the testator has expressed their wishes, and therefore the laws governing intestate succession do not apply. Intestate succession refers to the process that dictates how a decedent's assets are distributed when there is no valid will in place. Since there is a will in this scenario, the testator’s instructions will take precedence over any intestate laws, making this the correct choice.

In contrast, the other options represent various requirements and components that are essential in the context of creating and executing a will. Witnesses to the will are necessary to validate it and provide authenticity, an executor is needed to manage the estate and ensure proper distribution of assets per the will, and the testator must have legal capacity to create a valid will, which includes being of sound mind and of legal age. Therefore, while these elements are crucial for the administration of a will, they do not relate to the requirements when someone dies testate compared to the circumstances of intestate succession.
