Under Louisiana law, what is a key component in the validity of a testamentary document?

In Louisiana, a key component for the validity of a testamentary document, such as a will, is that the document must be written and signed by the testator. This requirement ensures that there is a clear, executed representation of the testator's intent regarding the distribution of their property after death. The signature signifies that the person creating the will has the mental capacity to do so and is acting voluntarily, making it a crucial element in the validity of the testament.

While other options mention requirements such as registration with the state or needing witnesses, Louisiana law does not mandate these for all types of wills. For example, while some forms of wills may require witnesses, not all testamentary documents have the same criteria. Therefore, the necessity of a written and signed document stands as the foundational legal requirement to uphold the testator's wishes in the eyes of the law.
