When someone dies without a valid will, the question of who inherits is answered not by the decedent’s expressed wishes, but by state law.

Intestate succession statutes define a fixed inheritance order that courts apply mechanically, distributing assets to surviving family members based on their legal relationship to the deceased rather than any personal or financial considerations.

For beneficiaries navigating an intestate estate, understanding how these rules work – and what rights they have within the probate process – is essential for managing expectations and protecting legitimate interests.

The Legal Inheritance Order

Intestate succession laws in the United States follow a hierarchical structure that prioritizes close family members over more distant relatives. While the specific rules vary by state, the general framework is consistent with the principles of the Uniform Probate Code, which many states have adopted in whole or in part.

Spouse and Children at the Top

The surviving spouse and the decedent’s children are always at the top of the intestate inheritance hierarchy. The precise division between them depends on state law and the family structure:

• Where all surviving children are also children of the surviving spouse: most states award the entire estate to the surviving spouse, recognizing that the children will ultimately inherit from the surviving parent. A minority of states divide the estate between the spouse and children.
• Where the decedent had children from a prior relationship: the estate is typically divided between the surviving spouse and all children, with the children sharing a defined portion equally. The spouse’s portion varies by state – commonly one-half to two-thirds.
• Where there is no surviving spouse: the estate passes to the children in equal shares.

The Representation Principle

Most states apply a principle called representation (or per stirpes distribution) when an heir predeceases the decedent and leaves their own descendants. Under this rule, the deceased heir’s share passes down to their children rather than reverting to the remaining heirs at the same level. For example, if a decedent’s child predeceased them, that child’s own children (the decedent’s grandchildren) would inherit the share their parent would have received.

Variations on this principle – per capita with representation and per capita at each generation – exist in different states and can produce meaningfully different distributions in families with multiple branches of differing size.

Parents, Siblings, and Beyond

If the decedent leaves no surviving spouse or children, the estate passes up the family tree to parents, then to siblings (and their descendants), then to grandparents, then to aunts and uncles, and so on through increasingly distant relatives. Most states ultimately provide that if no relative within a defined degree of kinship can be located, the estate escheats to the state.

Spousal Rights in Intestate Estates

The surviving spouse occupies a privileged position in intestate succession law, but several nuances affect exactly what that position means in practice.

Elective Share and Forced Heirship

Even in testate estates, most states give a surviving spouse the right to claim an ‘elective share’ – a minimum percentage of the estate regardless of what the will says. In an intestate estate, the elective share concept is largely irrelevant because the spouse is already entitled to the statutory intestate share. However, understanding this right is useful context: the law treats the surviving spouse as entitled to meaningful financial protection from the estate regardless of other circumstances.

Common-Law vs. Community Property States

The distinction between common-law states and community property states affects the surviving spouse’s baseline rights in significant ways. In community property states – Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin – each spouse already owns one-half of all property acquired during the marriage, regardless of whose name is on the title. At death, the decedent can only dispose of their own half. The surviving spouse’s half passes through intestacy or their own estate plan separately. This means that in a community property state, the surviving spouse may already own half of the apparent estate outright, with intestacy rules governing only the decedent’s half.

Domestic Partners and Unmarried Couples

Standard intestate succession laws do not recognize domestic partnerships or long-term unmarried relationships as conferring inheritance rights, with limited exceptions in states that have specifically extended intestate rights to registered domestic partners (California, Nevada, and a small number of others). An unmarried partner, regardless of the length or nature of the relationship, receives nothing under standard intestacy rules. This is one of the most significant practical limitations of dying without a will for people in non-marital relationships.

Children’s Rights in Intestate Probate

Children inherit equal shares in an intestate estate, but the definition of ‘child’ for purposes of intestate succession is more nuanced than it might appear.

Biological and Adopted Children

Biological children and legally adopted children are treated identically under intestate succession law in all U.S. states. There is no distinction based on whether the child is an adult or a minor; all children inherit equally.

Children Born Outside of Marriage

A child born outside of marriage inherits from their biological mother in all states without any additional requirements. Inheritance from the biological father requires that the paternity relationship was established during the father’s lifetime, through formal acknowledgment, a paternity proceeding, or a court determination. The specific requirements vary by state.

Stepchildren and Foster Children

Stepchildren who were not legally adopted by the decedent do not inherit as children under standard intestate succession laws in most states. Similarly, foster children who were not legally adopted do not inherit. This is an area where family expectations frequently diverge from legal reality, particularly in blended families where stepchildren were treated as full family members for decades without formal adoption.

Posthumous Children

A child conceived before the decedent’s death but born after it – called a posthumous child – is treated as having been born before the death for purposes of intestate succession in most states, and inherits accordingly.

Probate Asset Distribution Process

The distribution of an intestate estate does not happen automatically upon death. Assets must pass through the probate process before they are distributed to heirs. The distribution sequence follows a legally defined order:

• 1. Administrative expenses: The costs of administering the estate – filing fees, appraisal costs, attorney fees, and administrator compensation – are paid first.
• 2. Funeral and burial expenses: These have priority in most states, paid immediately after or concurrently with administrative costs.
• 3. Federal and state taxes: Outstanding income taxes of the decedent, estate taxes, and any taxes owed by the estate during administration are paid before distributions to heirs.
• 4. Secured creditors: Creditors holding security interests in specific assets (such as a mortgage lender or a car loan holder) must be paid from the proceeds of those assets before other claims.
• 5. Unsecured creditors: Credit card companies, medical providers, and other general unsecured creditors are paid from remaining estate funds.
• 6. Intestate heirs: What remains after all the above obligations are satisfied is distributed to heirs according to the intestate succession statute.

This distribution sequence matters because in estates with significant debts, heirs may receive substantially less than the gross estate value – or in some cases, nothing at all.

Court Supervision Requirements

Intestate estates in most states require probate court supervision for the administration and distribution process. The level of supervision depends on the state and whether any heirs or creditors request formal oversight.

Formal Supervised Administration

In states with formal probate requirements, the administrator must obtain court approval at multiple stages: appointment, sale of real property, final accounting, and distribution. This supervision protects heirs and creditors but extends the timeline and increases administrative costs. States like California, New York, and Florida are known for more formal requirements.

Independent Administration

Many states allow independent administration in intestate cases if all heirs consent or if the court grants authority for independent administration based on the circumstances. Under independent administration, the administrator can act without court approval for individual transactions, significantly reducing the time and cost of settling the estate.

Small Estate Procedures

If the total value of probate assets is below the state’s small estate threshold, heirs may collect assets using a small estate affidavit without opening formal probate, even in an intestate estate. The threshold varies considerably by state and applies only to the value of probate assets, not the total estate.

Contesting Intestate Distributions

The grounds for contesting an intestate distribution are narrower than those available in a testate estate, because there is no will to challenge. However, several categories of disputes can arise and be brought before the court.

Disputes Over Heirship

A person who claims to be an heir but is not included in the administrator’s petition – for example, an out-of-wedlock child whose paternity was not established, or a half-sibling the family was unaware of – can petition the court to be recognized as an heir. The court will require evidence of the claimed relationship before adjusting the distribution.

Challenges to the Administrator’s Actions

Heirs have the right to petition the court to review the administrator’s decisions, demand a formal accounting, and object to specific transactions or proposed distributions. If the administrator has mismanaged estate assets, an heir can petition for the administrator’s removal and surcharge – an order requiring the administrator to compensate the estate for losses caused by their misconduct.

Claims of Equitable Adjustment

In some cases, heirs argue that prior gifts or payments made by the decedent during their lifetime should be taken into account when calculating each heir’s intestate share. Many states allow for the concept of ‘advancement’ – a lifetime gift that is counted against the recipient heir’s intestate share – but this doctrine requires specific evidence and is not automatic.

What Happens When a Spouse Dies Without a Will

When a spouse dies without a will, the surviving partner’s inheritance rights depend entirely on state law, the structure of the couple’s assets, and the presence of children from the relationship or prior relationships.

In practical terms, most married couples hold significant assets in joint tenancy or with each other as designated beneficiaries – which means much of the estate may pass to the survivor automatically without going through the intestate probate process at all. The intestate rules primarily affect assets held solely in the deceased spouse’s name, such as individual bank accounts, real estate titled only in one spouse’s name, or investment accounts without a beneficiary designation.

Families facing this situation should take stock of all assets and their titling before assuming that full probate is required. Often, the surviving spouse can collect the bulk of the estate outside of probate and may need only a simplified procedure for a limited number of solely-held assets.

Summary

Intestate succession laws determine the inheritance rights of a decedent’s family members when no valid will exists. The hierarchy places the surviving spouse and children first, followed by parents, siblings, and more distant relatives. Distribution must follow the statutory formula, with no room for adjustments based on personal relationships, caregiving history, or the decedent’s informal wishes. Probate court supervision is required for administering and distributing intestate estates, though the level of supervision varies by state. Heirs can contest administrator decisions and heirship determinations through formal court proceedings, but the grounds for such challenges are more limited than those available in testate estate disputes.
