Wills, Trusts, and Estates
Satisfaction is when one gives willed property to his devisee as a gift before dying. Traditionally, gifts between executing the will and death are presumed to be in satisfaction of the will.
I.e., if one wills $50,000 to his son, then gives his son $30,000 before dying, his son will only get $20,000 from the will.
Satisfaction only applies to general devises. If items of specific devises are given before death, the devise is adeemed by extinction, not satisfaction.
It is basically the testate equivalent of advancements.
Like with advancements, the UPC greatly limits satisfaction by requiring testators' intent to adeem by satisfaction to be shown in writing. UPC § 2-609.
