testate

adj. of one who has died and left a valid will

n. one who has made a valid will

Intestacy is the condition of the estate of a person who dies owning property greater than the sum of his or her enforceable debts and funeral expenses without having made a valid will or other binding declaration; alternatively where such a will or declaration has been made, but only applies to part of the estate, the remaining estate forms the "Intestate Estate". Intestacy law, also referred to as the law of descent and distribution or intestate succession statutes, refers to the body of common law that determines who is entitled to the property from the estate under the rules of inheritance.
