What is the defining feature of a person's oral expression of property disposition?

The defining feature of a person's oral expression of property disposition is indeed a wish made during a final illness. This concept relates to how individuals may express their intentions regarding the distribution of their property, particularly when they are facing the end of their life. Such oral expressions can be significant in understanding a person's wishes, even if they may not meet the formal requirements of a will.

In many jurisdictions, a wish made during a final illness can sometimes be considered under the principles of testamentary intent and may carry weight in probate contexts, particularly if there are circumstances that suggest this expression reflects the person's true desires regarding their estate. This is often viewed in the context of what is referred to as "holographic wills" or informal testamentary documents, where the intent of the individual is emphasized even if formalities are lacking.

In contrast, other options refer to more formalized structures of property disposition, such as legally binding contracts or promises made before a notary, which require specific legal standards to be met and generally do not encompass the informal nature of an oral expression of intent made during a person's final days. A verbal agreement without witnesses also lacks the formal backing of testamentary capacity and documentation that would lend it the credibility needed for estate distribution purposes.
