Updated September 4, 2026. Quick answer: in Oklahoma, dying without a will does not mean the state keeps the estate; it means Oklahoma’s intestacy statute (84 Okla. Stat. § 213 (Descent and distribution, subsection B governs estates of persons dying on or after July 1, 1985, current law); half-blood rule at 84 Okla. Stat. § 222) decides who gets it, and the surviving spouse usually does not take everything. The single most common misunderstanding on this page: a stepchild or a child from an earlier relationship can cut the spouse’s share sharply below what most people assume.
What this guide covers
Who inherits from Oklahoma residents who die without a will is set by statute, not custom: 84 Okla. Stat. § 213 (Descent and distribution, subsection B governs estates of persons dying on or after July 1, 1985, current law); half-blood rule at 84 Okla. Stat. § 222 and the sections around it. It governs only the probate estate: what is left after retirement accounts and life insurance with a living named beneficiary, payable-on-death accounts, property in joint tenancy with survivorship, and anything already in a funded trust have already passed outside it. This page covers the spouse’s share, who inherits if there is no spouse, and the rules that can change the answer: half-blood relatives.
The spouse’s share
When the spouse takes everything: Under section 213.B.1.a, the surviving spouse takes the entire estate if there is no surviving issue, parent, brother or sister of the decedent.
When it is less than everything: Section 213.B.1: (a) No issue, no parent, no sibling; entire estate. (b) No issue, but a parent or sibling survives; spouse gets ALL property acquired by the joint industry of husband and wife during coverture, PLUS an undivided one-third (1/3) interest in the remaining estate. (c) Issue survive and ALL are also issue of the surviving spouse; spouse gets an undivided one-half (1/2) interest in ALL estate property (whether joint-industry or not), no reduction, since the family is not blended. (d) Issue survive and one or more are NOT also issue of the surviving spouse (BLENDED-FAMILY REDUCTION); spouse gets an undivided one-half (1/2) interest only in the joint-industry (marital-effort) property, PLUS an undivided equal part in the property of the decedent not acquired by the joint industry, with each of the living children of the decedent and the lawful issue of any deceased child by right of representation; i.e., on the decedent’s separate (non-marital-effort) property the spouse is treated as if just another child, taking a per-capita share alongside the decedent’s children rather than a flat fraction. Oklahoma is unusual in basing its blended-family distinction on a ‘joint industry during coverture’ (marital-effort) property class rather than a formal community-property system.
if there is no surviving issue, parent, brother or sister, the entire estate, or … an undivided equal part in the property of the decedent not acquired by the joint industry of the husband and wife during coverture with each of the living children of the decedent and the lawful issue of any deceased child by right of representation

If a DIY will fits your situation in Oklahoma
In Oklahoma, a surviving spouse can end up sharing the estate with a stepchild or a child from an earlier relationship under the default rules above; a will is what lets you decide that instead of the statute. LawDepot builds a state-specific last will and testament.

Who inherits if there is no spouse
Section 213.B.2: (a) to surviving children/issue by representation; (b) if none, to surviving parent(s) equally; (c) if none, to issue of parents by representation; (d) if none, half to paternal grandparents/their issue and half to maternal grandparents/their issue (or all to one side if the other side has no survivors); (e) if none of the above, to the next of kin in equal degree. Section 213.B.3: if no spouse, issue, parent, issue of parents, grandparent, or issue of a grandparent, the estate escheats to the state for the support of common schools.
Rules that change the outcome
Half-blood relatives: Generally a full/equal share, WITH ONE STATUTORY EXCEPTION for inherited (non-purchased) ancestral property. 84 Okla. Stat. section 222: ‘Kindred of the half-blood inherit equally with those of the whole blood in the same degree, unless the inheritance come to the intestate by descent, devise or gift of some one of his ancestors, in which case all those who are not of the blood of such ancestors must be excluded from such inheritance.’
What a will changes
A will does not just skip the statute above; it lets you choose who gets Oklahoma property that the intestacy rules would send somewhere else: a spouse who would otherwise share the estate with a stepchild, a partner who is not married and inherits nothing under intestacy at all, or specific people the statute’s ladder never reaches. It also lets you name an executor rather than leaving the court to appoint one. What it does not change: assets that already pass outside probate: a will has no effect on a beneficiary designation, a payable-on-death account, or property held in joint tenancy.
