What happens if you die without a will? Intestate succession explained

Dying without a will is called dying "intestate." When it happens, your state's intestacy laws — a default inheritance formula written into statute — take over and decide who inherits everything you own. The formula is rigid, it doesn't account for your actual relationships, and it often produces results that would surprise or distress the person who died.

This guide explains how intestate succession works, who ends up with what under different family structures, what assets are affected, and what it takes to avoid this outcome.

What intestacy actually means

Every state has intestacy laws — a hierarchy of relatives who inherit in a fixed order when someone dies without a valid will. The laws assume you would have wanted your assets to go to your closest legal relatives. The problem: "closest legal relative" is a legal category that often doesn't match "the people I actually care about most."

An intestate estate still goes through probate. The court appoints an "administrator" (instead of the executor named in a will) to manage the process. That administrator follows the state's formula for distribution, regardless of what the deceased person may have wanted.

The standard intestacy hierarchy

While details vary by state, the basic order of inheritance is consistent across most of the country:

1. Surviving spouse
2. Descendants (children, then grandchildren)
3. Parents
4. Siblings (and their descendants)
5. Extended relatives (aunts, uncles, cousins)
6. The state (if no relatives can be found — this is called "escheat")

Whoever is first in line inherits. If a person in line has died, their share typically passes to their children. At each tier, the law divides the estate among the people in that tier — it doesn't skip ahead to account for family relationships that don't fit the formula.

What intestacy means for different family structures

Married with children (all from the current marriage)

In many states, the surviving spouse inherits everything. In others, the estate is split between the spouse and the children. The exact split varies — California gives the spouse 100% if all children are also the spouse's children; some other states divide the estate so the spouse receives one-third to one-half and the children split the rest.

This can create practical problems when children are young. The estate going partly to minor children means those assets are controlled by a court-supervised custodianship until the children reach adulthood — not managed by the surviving parent the way the deceased person likely would have wanted.

Married with children from prior relationships

This is where intestacy often fails people. The surviving spouse and the deceased's children from a prior relationship may inherit simultaneously, in shares determined by state law. The proportions can create conflict and may leave stepparent and biological children in an adversarial relationship over the estate.

A surviving spouse may end up owning property jointly with children from a prior marriage — which may not have been what anyone wanted.

Unmarried partner

This is one of the most consequential gaps in intestacy law. An unmarried partner — regardless of how long the relationship lasted, how committed it was, or whether they lived together — inherits nothing under intestacy in virtually every state.

The estate passes to legal relatives instead: an estranged parent, distant siblings, or cousins the deceased person hadn't spoken to in years. If the couple owned property together but only in the deceased partner's name, the surviving partner has no legal claim to it under intestacy alone.

Blended family — stepchildren

Stepchildren are typically not included in intestacy unless they were legally adopted. A stepparent who raised children as their own but never formally adopted them leaves those children with no legal inheritance claim under intestacy laws.

Similarly, a stepchild who had a close relationship with a stepparent inherits nothing from that stepparent under intestacy — the estate passes to the stepparent's biological relatives instead.

Single person with no children

For a single adult with no children, the estate passes first to parents, then to siblings, then to more distant relatives. Friends, a partner, a charitable organization, a neighbor who provided care — none of them inherit anything. Extended family members who had no relationship with the person may end up with the estate.

Single parent

The estate passes to the children. If children are minors, a court-supervised custodianship controls their inheritance. If the other parent is living, the surviving parent does not automatically control the children's inheritance — a guardian of the estate may be required.

Which assets are affected by intestacy — and which are not

Intestacy governs only the assets that would have passed through a will. Several categories of assets pass entirely outside the estate, regardless of whether a will exists:

Assets NOT subject to intestacy:

• Accounts with named beneficiaries — retirement accounts (401(k), IRA), life insurance policies, and annuities pass directly to the named beneficiary, completely outside the probate process
• Joint tenancy property — property held as joint tenants with right of survivorship passes automatically to the surviving joint owner
• Payable-on-death (POD) accounts — bank accounts designated POD pass directly to the named recipient
• Trust assets — property held in a revocable or irrevocable trust passes according to the trust document, not intestacy law

Assets subject to intestacy:

• Bank accounts in the deceased person's name alone with no POD designation
• Real property in the deceased's name alone with no joint tenancy
• Personal property — vehicles, furniture, jewelry, clothing
• Business interests without a succession plan
• Any account without a named beneficiary

This distinction matters enormously. A person with a large retirement account and life insurance policy with named beneficiaries may have very little that actually passes through intestacy — even if they had no will. A person with substantial bank accounts, real estate, or business interests but no beneficiary designations and no will leaves a much larger intestate estate.

The cost of dying intestate

Intestate estates typically cost more and take longer to administer than estates with a valid will. Reasons:

No named executor. The court must appoint an administrator, which takes time and sometimes requires competing petitions from family members who each believe they should serve.

Court supervision. An intestate estate is often more closely supervised by the court, requiring additional filings and approvals.

Surety bonds. Courts often require administrators to post a surety bond — an insurance policy protecting the estate from the administrator's errors. This is a real cost that a well-drafted will typically waives.

Family conflict. Without clear documentation of intent, family members more often dispute how assets should be distributed, who should serve as administrator, and what debts exist. Disputes extend the timeline and increase attorney fees.

Distribution to wrong people. If assets end up with relatives who weren't intended to receive them, correcting that — if it can be corrected at all — requires legal proceedings.

The result: probate costs for an intestate estate commonly run higher than the cost of a will would have been.

Community property vs. common law states

The state you live in determines how marital property is classified, which affects intestacy.

Community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin, and Alaska by election) treat most assets acquired during marriage as equally owned by both spouses. At death, the surviving spouse typically already owns half of the community property outright — only the deceased spouse's half is subject to intestacy.

Common law states (all other states) treat property as owned by whoever holds title. A surviving spouse doesn't automatically own half of everything — they inherit a share under the intestacy formula, which varies by state.

This distinction can significantly affect how much a surviving spouse actually receives through intestacy, and it's one of the reasons that the intestacy outcome varies so much by state.

How to fix it: the minimum you need

The simplest fix for most people is a valid will. A will:

• Names who you want to receive your assets
• Names an executor (the person who manages the estate)
• Names a guardian for any minor children
• Can override the default intestacy formula entirely

For a single adult with straightforward finances, a simple will can be prepared quickly and is not expensive. Online will-preparation services allow many people to create a legally valid will without hiring an attorney.

For more complex situations — blended families, business interests, real property in multiple states, significant assets — an estate planning attorney can help you design a plan that works.

Beyond the will, two additional steps close most of the gaps that intestacy creates:

Name beneficiaries on all accounts. Retirement accounts, life insurance, bank accounts (POD designations), and investment accounts should all have current, correct beneficiary designations. These pass outside probate regardless of what the will says — and outside intestacy if there's no will. Review them after any major life change (marriage, divorce, birth, death of a named beneficiary).

Consider a revocable living trust if you have substantial assets, real estate in multiple states, or want to avoid probate entirely. A trust passes assets to your beneficiaries without going through the probate process at all. See the what is a revocable living trust guide for a full explanation of how trusts work and when they make sense.

Frequently asked questions

If I have a will, can it still be challenged?

Yes. A will can be contested on several grounds: lack of testamentary capacity (the person didn't understand what they were signing), undue influence (someone pressured them), fraud, or improper execution (the will wasn't witnessed correctly). Challenges are more common in high-asset estates or when the distribution is surprising to family members. A properly drafted and witnessed will is much harder to challenge than a handwritten or informal one.

Do I need a will if I'm young and don't have many assets?

Yes, especially if you have a partner (particularly an unmarried one), if you have opinions about who should receive your belongings, or if you have people who depend on you. Even a small estate handled under intestacy can create real difficulties for the people you love. The other document most young adults should have is a healthcare directive — a document naming who makes medical decisions if you're incapacitated. See the end-of-life documents checklist for the full list of documents worth having.

Can a surviving partner claim anything under intestacy?

In virtually every state, no — unless the couple was legally married or in a registered domestic partnership. Cohabiting partners, regardless of the length or depth of the relationship, have no inheritance rights under intestacy. Some states have limited protections for certain claims (such as a home the couple shared), but these protections are narrow and fact-specific. This is one of the strongest arguments for a will for anyone in an unmarried partnership.

What happens to digital assets under intestacy?

Digital assets — accounts, cryptocurrency, online content, digital files — are increasingly valuable and increasingly disputed. Intestacy law doesn't specifically address them, and many digital platforms have their own terms of service that restrict or prevent inheritance. A will can name someone to receive digital assets and authorize access; many states now have laws (based on the Revised Uniform Fiduciary Access to Digital Assets Act) that allow a will to authorize access to digital accounts. Without any instructions, a family may find it very difficult to access or transfer these assets.

Is dying intestate always bad?

Not necessarily. For a simple estate — married couple, all assets jointly held or with named beneficiaries, no unusual family complexity — intestacy may produce the same result as a will would have, with fewer legal costs. The risk is that "simple" estates often aren't as simple as they seem, and the consequences of intestacy becoming a problem land on the surviving family members at the worst possible time.
