Intestate Succession: Who Inherits Without a Will?
Intestate succession is the set of state rules that decides who inherits when someone dies without a valid will (or when a will does not cover all property). The outcome can be predictable in simple families and unexpectedly complicated in blended families, second marriages, or when significant assets pass outside probate. This guide explains the typical process, who inherits, what gets left out, and practical ways to avoid unintended results.
Intestate succession explained in plain terms
Dying “intestate” means there is no valid will directing what happens to the probate estate. “Partial intestacy” happens when a will exists but fails to dispose of everything—often because an asset was acquired later, a residuary clause is missing, or a beneficiary designation was never updated.
Intestacy laws are state-specific. Two states can sound similar on paper but differ sharply in the spouse’s share, who counts as a “child,” and whether step-relatives are included. Many states also draw from (or resemble) the Uniform Probate Code, but not all states adopt it, and those that do may modify it.
Intestacy doesn’t decide everything. Many assets transfer by contract or title—like retirement accounts with a named beneficiary, life insurance, or jointly owned property with rights of survivorship—outside the intestate statute. Intestacy typically governs only what remains in the probate estate.
Because distributions must be authorized, a court-supervised probate process is commonly required to appoint a personal representative (often called an “administrator” when there is no will) and oversee the transfer of assets to heirs.
What happens right after death when there is no will
Usually, an interested person (a spouse, adult child, creditor, or other party with standing) petitions the probate court to open an estate and request appointment as administrator/personal representative. If multiple people apply—or family members disagree—the court may need to decide who serves.
The court then determines the legal heirs under state law. If relationships are unclear, some states require affidavits of heirship, formal testimony, or additional documentation (marriage certificates, divorce decrees, adoption records, or proof of parentage).
Once appointed, the administrator gathers and secures assets, obtains date-of-death values, and requests the official paperwork institutions require (often “letters of administration”). Those letters are what allow banks, brokerages, and buyers to work with the estate.
Next comes the “priority stack”: valid debts, expenses, and taxes are typically paid before heirs receive anything. Creditor notices may be published, mailed, or both depending on the state. If disputes erupt—alleged spouse status, contested paternity, missing heirs, or challenges to property ownership—the case can move from routine administration into litigation, extending the timeline and costs.
Who inherits under intestate laws (common patterns)
In many states, the surviving spouse and children are first in line, but the spouse’s share varies widely. A common turning point is whether all children are also the children of the surviving spouse. In some states, a spouse receives a larger portion (or the entire estate) when all children are shared; when there are children from a prior relationship, the children may receive a bigger share than families expect.
If there is no spouse and no children, inheritance often “climbs” the family tree: parents, then siblings, then more remote relatives such as grandparents, aunts/uncles, and cousins. Stepchildren usually do not inherit automatically unless legally adopted. Foster children generally do not inherit under intestacy because intestacy follows legal parent-child relationships.
Unmarried partners generally do not inherit under intestate succession without special legal status. If no qualifying heirs can be found, the estate may “escheat” to the state—meaning the state becomes the recipient under statute.

What property intestate succession controls (and what it does not)
Typical probate timeline, costs, and friction points
Typical cost categories include court filing fees, publication/notice costs, appraisals, administrator commissions (where allowed), attorney fees, and taxes. Federal estate tax applies only above certain thresholds, but income taxes and state-level taxes may still be relevant. General tax background is available from the IRS estate and gift taxes information page.
| Stage | What happens | Common delay | How to reduce friction |
|---|---|---|---|
| Court appointment | Petition filed; administrator appointed | Competing petitions; unclear heirs | Collect marriage/divorce/adoption records; provide family tree info |
| Inventory & valuation | Assets located, secured, valued | Missing statements; hard-to-value property | Maintain an updated account list; keep deed/title copies |
| Debt & tax handling | Creditor notices; claims paid; tax filings | Unknown debts; late claims; tax questions | Pull credit reports; locate prior tax returns; track bills |
| Distribution | Heirs receive shares under statute | Heir disputes; minor heirs; missing heirs | Use heirship affidavits where accepted; consider mediation |

FAQ
Does a surviving spouse automatically inherit everything if there is no will?
No. A surviving spouse’s share depends on state law and often changes based on whether the decedent had children and whether those children are also the spouse’s; community property and elective share rules can also affect the outcome.
Do stepchildren inherit in intestate succession?
Usually not. Intestate succession generally follows legal parent-child relationships, so stepchildren typically inherit only if they were legally adopted or included through planning tools such as a will or trust.
Can intestate succession be avoided without a will?
Yes. Revocable living trusts, updated beneficiary designations, TOD/POD registrations, and certain forms of joint ownership can transfer assets outside intestacy, but the tools must be coordinated to avoid gaps and unintended results.
