Updated September 4, 2026. Quick answer: in Iowa, dying without a will does not mean the state keeps the estate; it means Iowa’s intestacy statute (Iowa Code §§633.211, 633.212, 633.219 (Title XV, Probate Code)) 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 Iowa residents who die without a will is set by statute, not custom: Iowa Code §§633.211, 633.212, 633.219 (Title XV, Probate Code) 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: If the decedent dies intestate leaving a surviving spouse and leaving no issue or leaving issue all of whom are the issue of the surviving spouse, the surviving spouse receives the Track 1 share below (section 633.211); which in practice is effectively the whole estate.
When it is less than everything: Iowa uses a two-track, non-UPC formula (no dollar-plus-fraction tiers). Track 1, no blended family (section 633.211, decedent has no issue, or all issue are also the spouse’s): spouse receives (1) all legal/equitable real property interests held by decedent during the marriage that were not judicially sold, (2) all head-of-family exempt personal property, and (3) all other personal property not needed for debts/charges, i.e. essentially the entire net estate. Track 2, blended-family reduction (section 633.212, decedent has issue SOME of whom are NOT the spouse’s issue): spouse receives only (1) one-half in value of the real property interests described above, (2) all exempt personal property, and (3) one-half of other personal property, but with a floor: if the property received by the surviving spouse under this section is not equal in value to fifty thousand dollars, additional estate property (up to the whole net estate) is added until the spouse’s total reaches $50,000. The reduction triggers specifically when any of decedent’s children are not also the spouse’s children, and is cushioned by a statutory $50,000 minimum.
If the decedent dies intestate leaving a surviving spouse and leaving issue some of whom are not the issue of the surviving spouse, the surviving spouse shall receive the following share: 1. One-half in value of all the legal or equitable estates in real property possessed by the decedent at any time during the marriage.

If a DIY will fits your situation in Iowa
In Iowa, 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 633.219(1)-(7): (1) issue per stirpes; (2) if no issue, to parents equally (deceased parent’s share to survivor); (3) if no issue or parent, split into two equal shares, one to issue of decedent’s mother per stirpes, one to issue of decedent’s father per stirpes (collapsing to one side if the other parent left no issue); (4) if none of the above, to grandparents/their issue, split paternal half/maternal half; (5) great-grandparents/their issue, split equally per set; (6) issue of a deceased spouse of the decedent, per stirpes; (7) escheat to the State of Iowa.
Rules that change the outcome
Half-blood relatives: No section is expressly labeled ‘half blood.’ Iowa achieves a differential outcome structurally through section 633.219(3): when there is no surviving issue or parent, the estate is split into a maternal-line half and a paternal-line half, each distributed per stirpes. A whole-blood sibling (sharing both parents) is issue of both lines and shares in both halves; a half-blood sibling (sharing only one parent) is issue of only one line and shares in only that half, producing an unequal outcome without any statute using the words ‘half blood’ or stating a fixed fractional reduction.
What a will changes
A will does not just skip the statute above; it lets you choose who gets Iowa 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.
