Next of kin
From Wikipedia, the free encyclopedia
Next of kin is the term used to describe a person's closest living blood relative or relatives.
In many legal systems, rights regarding inheritance and substitute decision making capacity (for example, in a medical emergency) where no clear will or instructions have been given, and the person has no spouse, flow to their closest relative (regardless of the age with a representative appointed if a minor), usually a child, a parent or a sibling. However, there are people without any close adult relatives and, in such a case, decision making power often flows to a nephew, first cousin, aunt, uncle, or grandparent.
For example, if a person dies intestate, the laws of most jurisdictions require the estate to be distributed to the person's spouse and/or children. However, if there are none of these, the estate can often be distributed to the next closest group of living relatives, whether they be parents, grandparents, cousins, aunts & uncles, or even second cousins in extreme cases. If a person dies intestate with no identifiable next of kin, the person's estate generally escheats (i.e., legally reverts) to the government.
Similarly, the decisions about funeral arrangements for an unmarried person without children are also made by the next closest relative.
In cases of medical emergency, where a person is incapable (either legally because of age or mental infirmity, or because they are unconscious) of making decisions for themselves and they have no spouse or children, medical decisions can be made by the next of kin in preference to the wishes of medical personnel.
The inability of persons who are not in a legal marriage to make decisions with respect to the care of a live-in partner have resulted in many jurisdictions giving live-in partners rights equivalent to a spouse in such situations, even though most jurisdictions still do not require non-spouses to be made beneficiaries of estates (it is improper in most jurisdictions to disinherit a spouse). The inability of same-sex partners to have rights with respect to a partner's medical care or funeral arrangements over and above those of the next of kin is one of the main reasons behind litigation to require same-sex marriage or its equivalent.
For the purposes of next of kin, adopted children are treated as blood relatives. However, relatives by marriage are never considered next of kin.
The opposite term is a stranger in blood.
[edit] Order of Precedence in U.S.
"American statutes typically provide that, in absence of issue and subject to the share of a surviving spouse, interstate property passes to the parents or to the surviving parent of the decedent."[1] Under the civil law system of computation and its various modified forms that are widely adopted by statute in the United States, "a claimant's degree of kinship is the total of (1) the number of the steps, counting one from each generation, from the decedent up to the nearest common ancestor of the decedent and the claimant, and (2) the number of teps from the common ancestor down to the claimant."[1] "The claimant having the lowest segree count (i.e., the nearest or next of kin) is entitled to the property."[1] "If there are two or more claimants who stand in equal degree of kinship to the decedent, they share per capita."[1]
Thus, the following conditions determine the usual order of precedence:
Under these rules, an order of precedence is established. Here are the first few in the order (specifically, those up to degree 6):
