Intestate Succession Laws Across U.S. Jurisdictions
Intestate succession governs the distribution of a decedent's probate estate when no valid will controls the disposition of assets. Each U.S. jurisdiction maintains its own statutory scheme, producing a patchwork of rules that determine who inherits, in what share, and under what conditions. These laws intersect with federal vs. state estate law frameworks, probate court procedures, and spousal rights doctrines that vary significantly across the 50 states and the District of Columbia. Understanding the structure of these statutes is essential for evaluating how an estate will be administered in the absence of testamentary planning.
Definition and Scope
Intestate succession is the legal process by which a state distributes a decedent's estate assets when the decedent dies without a will, when an existing will is declared invalid, or when a will fails to dispose of all estate property — the last situation producing what is called partial intestacy. The governing authority is exclusively state law; no federal intestacy statute exists for general property distribution, though federal law intersects with certain asset classes such as ERISA-governed retirement accounts (see retirement accounts estate law).
The scope of intestate laws is limited to probate assets — property titled solely in the decedent's name without a designated beneficiary. Assets passing by beneficiary designation, joint tenancy with right of survivorship, or revocable living trust fall outside the intestacy framework entirely (see non-probate asset law).
The Uniform Law Commission (ULC) published the Uniform Probate Code (UPC) to provide a model statutory framework that states may adopt in whole or in part (Uniform Law Commission, Uniform Probate Code). As of the ULC's published adoption records, 18 states have adopted substantial portions of the UPC, while the remainder have enacted independent intestacy statutes derived from common-law traditions or earlier uniform acts.
How It Works
When a decedent dies intestate, the probate court system opens an administration proceeding. A personal representative — typically called an administrator rather than an executor — is appointed by the court, often prioritizing the surviving spouse, then adult children, then other heirs, following a statutory priority ladder.
The distribution process follows a structured sequence:
- Identify the decedent's probate estate. Non-probate assets are segregated and pass outside the proceeding.
- Determine the applicable state law. The law of the state where real property is located governs real estate; the law of the decedent's domicile governs personal property.
- Establish the surviving heirs. Courts apply the jurisdiction's definition of heir, which determines qualifying relatives and their priority tiers.
- Calculate each heir's share. Statutes specify fractional shares based on the presence or absence of a surviving spouse, children, parents, and more distant relatives.
- Apply per stirpes or per capita distribution rules. These allocation methods determine how a deceased heir's share is redistributed among that heir's descendants.
- Distribute after payment of debts and administration costs. Creditor claims, taxes, and court fees are satisfied before distribution to heirs.
Under the UPC model, a surviving spouse who is also the parent of all the decedent's children may take the entire estate. Where the decedent has children from a prior relationship, the spouse's share is reduced to a fixed dollar threshold plus a fractional share of the remainder (UPC § 2-102).
Per stirpes distribution — the most common approach — divides a predeceased heir's share equally among that heir's direct descendants. The competing per capita at each generation method, adopted by the UPC, pools shares at each generational level before redistribution, often producing different numerical outcomes when multiple branches of a family are involved.
Common Scenarios
Scenario 1 — Surviving Spouse, No Children: In most UPC-adopting states, the surviving spouse inherits 100% of the intestate estate. In non-UPC states such as Georgia (O.C.G.A. § 53-2-1), the surviving spouse takes an equal share alongside the decedent's parents if the parents survive, potentially limiting the spousal share.
Scenario 2 — Children but No Surviving Spouse: All intestate property passes in equal shares to the decedent's children. If a child predeceased the decedent, that child's share passes to the child's own descendants under the applicable representation rule.
Scenario 3 — No Spouse, No Descendants: The estate passes to the decedent's surviving parents equally, or entirely to the surviving parent if only one survives. If both parents are deceased, the estate cascades to siblings, then to more distant collateral relatives.
Scenario 4 — Blended Families: Stepchildren generally do not qualify as heirs under most state intestacy statutes unless formally adopted. This outcome contrasts directly with the treatment of biological children or legally adopted children, who hold identical statutory rights in all U.S. jurisdictions. Unmarried partners, regardless of relationship duration, receive no intestate share in states without registered domestic partnership statutes, making this one of the most significant gaps in default inheritance law.
Scenario 5 — Half-Blood Relatives: State treatment diverges sharply. The UPC treats half-blood relatives identically to whole-blood relatives. Approximately 10 states reduce the half-blood heir's share by one-half compared to a whole-blood heir in the same degree of kinship, a distinction traceable to early English common-law rules retained in older state codes.
Community property states — Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — apply a separate layer of analysis, because the surviving spouse already holds an undivided one-half interest in community property by operation of law (see community property estate law). Only the decedent's half of community property, along with any separate property, passes through the intestacy framework.
Decision Boundaries
Intestate succession statutes contain defined boundaries that determine whether a claimant qualifies as an heir, whether specific property is subject to the statute, and which state's law governs disputed assets.
Qualifying Heir vs. Non-Qualifying Claimant
The distinction between a legal heir and a mere claimant turns on statutory relationship definitions. Biological children conceived before death but born after the decedent's death (posthumous children) are recognized as heirs in all UPC jurisdictions. Children conceived through assisted reproduction after the decedent's death present an evolving boundary; fewer than half of U.S. states have enacted statutes addressing this class of heir, and court decisions vary considerably.
Adopted children are treated as natural children of the adoptive parent for intestacy purposes in all 50 states (Uniform Adoption Act, ULC). However, equitable adoption — a doctrine recognizing children who lived as family members without formal legal adoption — is accepted in roughly 27 states, though the evidentiary threshold and resulting inheritance rights differ by jurisdiction.
Spousal Share Limits and the Elective Share
Intestate statutes set the default spousal share, but the elective share spousal rights framework operates as a separate statutory floor. Where a surviving spouse would receive less through intestacy than the elective share statute guarantees, the spouse may elect against the estate. The UPC's augmented estate approach calculates the elective share at 50% of the "marital-portion" asset pool, a figure that grows with the length of the marriage on a sliding scale up to 15 years (UPC § 2-202).
Advancements and Hotchpot
Most UPC-adopting states recognize the doctrine of advancement, under which inter vivos gifts to an heir may be charged against that heir's intestate share if the decedent declared the gift an advancement in a contemporaneous writing. The heir must bring the advanced amount back into a hotchpot calculation before shares are apportioned. Non-UPC states vary on whether the doctrine requires affirmative written evidence or whether oral testimony suffices.
Escheat as the Terminal Boundary
When no qualifying heir can be identified through the statutory hierarchy — typically exhausted after reaching the degree of second cousins or more distant relatives — the estate escheats to the state. Each state's escheat statute specifies the terminal heir degree; California, for example, extends intestate succession to the decedent's grandparents' descendants before escheating (California Probate Code § 6402). The estate planning statutory sources that govern these boundaries are codified at the state level and are subject to legislative amendment without federal notice requirements.
