A more thorough explanation:

Definition: Vie (vee) is a French word that means life. It is commonly used in Law French phrases such as cestui que vie and pur autre vie.

• Cestui que vie: This is a legal term that refers to a person who is entitled to receive the income from a property or estate for the duration of their life.
• Pur autre vie: This is another legal term that means "for the life of another." It is used to describe a situation where a person has a life interest in a property or estate that is tied to the life of someone else.

These examples illustrate how the term VIE is used in legal contexts to describe the duration of a person's life and how it relates to property or estate rights.
