Quick answer: In California, “next of kin” means your closest living relatives in this order: surviving spouse or registered domestic partner first, then children, then parents, then siblings, then more distant relatives. When someone dies without a will, that next-of-kin order in California determines who inherits the estate under the state’s intestate succession rules. A spouse keeps all community property and a share of separate property. Children, parents, and siblings split what the spouse does not take.
A relative died and left no will, and now the family is staring at the house, the bank accounts, and each other, trying to figure out who actually gets what. California already has the answer written into law. When there is no will, the state decides who inherits and in what shares. That set of rules is called intestate succession, and the relatives it points to are the “next of kin.”
Below is the plain-English version of next of kin California law: what the term means, the exact order of priority the state follows, and how a spouse’s share is calculated.
What Does Next of Kin Mean in California?
“Next of kin” means a person’s closest living relatives. In an estate context it usually points to a surviving spouse or registered domestic partner, then children, then other blood relatives in descending order.
The term matters most in two situations. The first is incapacity: when someone can no longer make their own medical or financial decisions, a close relative may be asked to step in. The second is intestacy, which is the legal word for dying without a valid will. When that happens, California’s Probate Code (starting at § 6400) sets a strict order for who inherits based on the family relationship to the deceased.
California does not recognize common-law marriage, so an unmarried partner is not next of kin no matter how long the relationship lasted. Registered domestic partners, however, have the same intestate rights as spouses.
Next of Kin Order in California: Who Inherits First
If there is no will, California hands the estate to relatives in this next-of-kin order. Each level only inherits if no one above them survives:
- Surviving spouse or registered domestic partner (takes all community property, plus a share of separate property)
- Children, and the children of any child who died before the decedent (grandchildren step into their parent’s place)
- Parents
- Siblings (brothers and sisters, and their children — your nieces and nephews)
- Grandparents
- Aunts and uncles, then cousins
- Children of a spouse who died before the decedent
- Next of kin in the nearest degree, and finally the predeceased spouse’s parents or their children
If no relative can be found at all, the estate “escheats” — meaning it goes to the State of California. That outcome is rare, but it is what the law provides when there is truly no one left.
Who Is Next of Kin in California When There Is a Spouse?
This is the part that trips up most families, because the answer depends on two things: whether the property is community or separate, and who else survived.
First, the two kinds of property:
- Community property is what the couple built during the marriage, such as wages earned and most things bought with them.
- Separate property is what the deceased owned before the marriage, or received during it as a gift or an inheritance.
The surviving spouse or registered domestic partner keeps all of the community property. Separate property is where the split happens, under Probate Code § 6401:
| Who survives along with the spouse | Spouse’s share of separate property |
|---|---|
| No children, no parents, no siblings | All of it |
| One child (or that child’s descendants), or no children but a parent or siblings | One-half |
| Two or more children (or one child plus the descendants of another) | One-third |
Whatever separate property the spouse does not take goes to the children (or parents or siblings) who triggered the split. So a spouse with two surviving children keeps all the community property plus one-third of the separate property, and the two children share the remaining two-thirds.
California Next of Kin Laws: Rules That Surprise People
- Half-siblings inherit like full siblings. California treats a half-brother or half-sister the same as a full one.
- Adopted children inherit like biological children. Legal adoption puts a child on equal footing with the decedent’s other children.
- Stepchildren usually do not inherit. A stepchild has no automatic right to inherit unless they were legally adopted.
- Unmarried partners do not inherit. California does not recognize common-law marriage. If you were never legally married or registered as domestic partners, your partner is not next of kin, no matter how long you were together.
- A verbal promise is not enough. For anyone outside the family to inherit, there has to be a valid written will or trust. “He always said the house was mine” carries no legal weight on its own.
What This Means for Probate
When there is no will, the estate still has to go through probate — the court process for paying final debts and transferring what is left. The court appoints a personal representative to handle it, and the intestate rules above decide who receives the assets. Smaller estates may qualify for a simplified process, but real estate usually pushes an estate into full probate. If you are starting one, here is more on how California probate works.
Not everything runs through probate or intestate succession. Some assets pass straight to whoever is named on them, no matter what the family tree says:
- Life insurance with a named beneficiary
- Retirement accounts such as 401(k)s and IRAs
- Property held in joint tenancy
Those go directly to the named person or surviving co-owner.
How to Avoid All of This
Intestate succession is the state’s backup plan, and it rarely matches what a person would have chosen. A will or a living trust lets you decide for yourself who inherits, name a guardian for minor children, plan around a blended family, and cut down on the fights that often follow an unclear estate. A little estate planning now keeps your family out of the default rules entirely. And once a plan is in place, it is worth a look every few years, because families and finances change.
Frequently Asked Questions
What does next of kin mean in California?
Next of kin in California means your closest living relatives, ranked in the order the law uses when someone dies without a will. The list starts with a surviving spouse or registered domestic partner, then moves to children, parents, siblings, and more distant relatives. Only the closest living relative (or group at the same level) inherits.
Who is considered next of kin in California?
Your closest living relatives, in order: a surviving spouse or registered domestic partner first, then your children, then your parents, then your siblings, and on down to grandparents, aunts, uncles, and cousins. The law works through that list until it finds someone living.
Does the surviving spouse get everything?
Not always. A spouse keeps all of the couple’s community property. Separate property is shared: the spouse takes all of it only if there are no children, parents, or siblings. With one child the spouse gets half the separate property, and with two or more children the spouse gets one-third.
Who has more rights — a spouse or a child in California?
The spouse comes first in California’s next-of-kin order. The surviving spouse keeps 100% of community property and at least half of separate property in most cases. Children share only the portion of separate property that the spouse does not receive, and they inherit nothing from community property when a spouse survives.
What happens if there is no spouse and no children?
The estate moves to the next level of relatives: first the parents, then brothers and sisters and their children, then grandparents, then aunts, uncles, and cousins. If no relative can be located at all, the estate passes to the State of California.
Can an unmarried partner inherit without a will?
No. California does not recognize common-law marriage, so a partner who was never legally married to or registered as a domestic partner with the deceased inherits nothing under intestate succession. The only way to provide for them is a will or trust.
