Justipedia explains Next of Kin
Determining/finding the decedent’s next of kin is an important step in estate law when an estate holder dies without leaving a will. Many jurisdictions statutorily require estates to be divided among the next of kin when a will is absent. This practice reflects the assumption that a deceased individual’s next of kin are the closest, most loved people in the deceased’s life, and that the deceased would naturally want the estate to go to these people.
