An heir to an estate is a relative the law identifies to inherit from someone who died without a valid will, with a surviving spouse first in line, followed by children and their descendants, then parents, siblings, and more distant relatives in that order. When there is a will, the people who inherit are technically beneficiaries rather than heirs, though the words are used interchangeably in everyday life. The practical questions are the same either way: where do you stand in the priority order, what assets actually pass through the estate, and what can keep you from receiving anything.
Heir or Beneficiary
The strict legal meaning of “heir” is a relative who inherits under state intestate succession law when there is no will. A beneficiary, by contrast, is someone specifically named in a will or trust. A will can leave property to anyone the person chose: friends, charities, distant relatives, a neighbor. It overrides the default order the state would otherwise impose.
The distinction becomes important when a will is contested or found partially invalid. Any property the will does not validly cover passes to legal heirs under intestate succession, not to people the deceased informally promised it to.
The Order of Heirs Under State Law
Every state has its own intestate succession statute, and the specific fractions differ, but the priority order is broadly similar across the country.
Surviving Spouse
A surviving spouse almost always comes first. If the deceased left no children and no surviving parents, the spouse typically inherits everything. Where there are children only from the marriage, many states still give the entire estate to the spouse. The math gets more complicated when either the deceased or the surviving spouse had children from a prior relationship; in those cases the spouse often takes a set dollar amount plus a fraction of the balance, with the children splitting the rest.
Community property states handle this differently. Each spouse already owns half of all property acquired during the marriage, so the surviving spouse automatically keeps their half. Only the deceased spouse’s separate property and their half of community property enter the estate for distribution.
Children
With no surviving spouse, the deceased’s children inherit the entire intestate estate in equal shares. When a spouse and children both survive, most states divide the estate between them under statutory formulas that vary by jurisdiction.
Parents, Siblings, and Extended Family
If there is no surviving spouse and no children or other descendants, parents are next. If both parents have died, siblings inherit. After siblings, priority typically extends to grandparents, then aunts and uncles, then cousins. Each step down the family tree only matters when no one closer survives.
When an Heir Has Already Died
One of the most common questions involves what happens when someone who would have been an heir dies before the person whose estate is being distributed. In nearly every state, that deceased heir’s share passes down to their own children. The doctrine goes by several names depending on the jurisdiction: right of representation, per stirpes, or per capita at each generation.
In practice: a parent dies intestate leaving three children, but one of those children died years earlier and left two grandchildren. The estate splits into three shares. The two surviving children each take one. The two grandchildren split the third share that would have gone to their deceased parent. Without this rule, the grandchildren would inherit nothing despite being direct descendants. States differ on the exact mechanics when multiple heirs in the same generation have predeceased, but the core principle is consistent: a deceased heir’s line steps into their place.
Family Situations That Complicate Heirship
Not every family fits the standard model. Intestate succession laws account for several non-traditional relationships, and some of the results surprise people.
- Adopted children. Treated identically to biological children. An adopted child inherits from adoptive parents exactly as if born into the family. In most states, adoption severs the legal parent-child relationship with the biological parents, so the adopted child no longer inherits from them under intestate succession.
- Half-siblings. Siblings who share one biological parent with the deceased generally inherit on equal footing with full siblings.
- Non-marital children. A child born outside marriage can inherit from a biological parent, but paternity (or in rarer cases maternity) usually must be legally established through a court order, voluntary acknowledgment, or genetic testing.
- Posthumous children. A child conceived before the deceased’s death but born afterward is treated as if born during the parent’s lifetime.
- Stepchildren. No automatic inheritance rights from a stepparent. A stepchild inherits only if the stepparent legally adopted them or specifically named them as a beneficiary. This catches many families off guard.
- Common law spouses. Only a handful of states still recognize new common law marriages. In those states a common law spouse has the same inheritance rights as a formally married one. In states that do not recognize common law marriage, a surviving partner has no spousal inheritance rights at all, regardless of how long the couple lived together. Some states will recognize a common law marriage validly formed in another state.
Assets That Never Reach Heirs
A significant share of what people own never passes through the estate at all. Intestate succession laws and even a will have no control over these assets, because they transfer automatically to a named beneficiary or co-owner at death, outside the probate process entirely.
The most common examples are life insurance policies with a named beneficiary, retirement accounts like 401(k)s and IRAs with beneficiary designations, bank accounts set up as payable-on-death, investment accounts registered as transfer-on-death, property held in joint tenancy with right of survivorship, and assets placed in a living trust. For many families these non-probate assets represent the bulk of the wealth. An heir who expects to inherit under a will or intestate succession may find that most of the money already went directly to whoever was listed on a beneficiary form filed years ago.
When an Heir Gets Blocked or Reduced
Being next in line under intestate succession, or even being named in a will, does not guarantee you will actually receive anything. Several doctrines can block or shrink an inheritance.
The Slayer Rule
Every state has some version of the slayer rule, which prevents someone from inheriting from a person they intentionally killed. The rule treats the killer as if they died before the victim, so the inheritance passes to whoever would have been next in line. A criminal conviction creates a presumption that the killing was intentional, but a conviction is not required: courts can apply the slayer rule after an acquittal or when no charges were filed, using a lower civil standard of proof. The most consistent exception involves cases where the killer is found not responsible by reason of insanity, which undercuts the intentional-act requirement.
Spousal Elective Share
A majority of states have elective share statutes that prevent one spouse from completely disinheriting the other. Even if a will leaves the surviving spouse nothing, that spouse can elect to claim a statutory minimum, typically ranging from about one-third to one-half of the estate. This is a feature of separate property states. Community property states handle the problem differently, since the surviving spouse already owns half the marital property outright.
Disinheritance by Will
Outside the spousal elective share, a will can disinherit almost anyone. A parent can leave an adult child nothing. A sibling can be excluded entirely. The will simply needs to be clear about the intent. Children accidentally omitted from a will drafted before their birth may have a statutory right to a share in some states, but deliberate exclusion is generally enforceable.
Debts Come Out First
Heirs inherit what is left after the estate pays its obligations, not the gross value of what the deceased owned. Creditors are paid from estate assets before anything is distributed. If the estate cannot cover all its debts, heirs may receive little or nothing. One point worth being clear on: you are not personally responsible for a deceased relative’s debts simply because you inherited from them. Debts belong to the estate, not to you, unless you were a co-signer, a joint account holder, or a surviving spouse in a community property state where the debt is a marital obligation.1Consumer Financial Protection Bureau.

Taxes and the Step-Up in Basis
The federal estate tax applies only to estates exceeding the basic exclusion amount, which for 2026 is $15,000,000 per individual. A married couple using portability can pass up to $30 million free of federal estate tax. The rate on amounts above the exemption is 40%. This higher exemption was made permanent under the One Big Beautiful Bill Act, signed into law on July 4, 2025, replacing the temporary increase set to expire under the Tax Cuts and Jobs Act.2Internal Revenue Service. What’s New — Estate and Gift Tax The exemption will be adjusted annually for inflation starting in 2027. For the vast majority of estates, no federal estate tax is owed.
About half a dozen states impose a separate inheritance tax paid by the heir rather than the estate. Rates and exemptions depend on the state and often on the heir’s relationship to the deceased. Spouses are typically exempt, and closer relatives usually face lower rates or higher thresholds than unrelated beneficiaries. A handful of additional states impose their own estate tax with lower exemption thresholds than the federal level.
One significant tax advantage for heirs is the step-up in basis. When you inherit property, your tax basis in it is generally its fair market value on the date of death, not what the deceased originally paid.3Office of the Law Revision Counsel. 26 US Code 1014 – Basis of Property Acquired From a Decedent If a parent bought stock for $10,000 and it was worth $200,000 at death, you could sell it immediately for $200,000 and owe no capital gains tax. The step-up covers most inherited assets, including real estate, stocks, and business interests. It does not apply to retirement accounts like IRAs and 401(k)s, where withdrawals are taxed as ordinary income regardless of when the contributions were made.4eCFR. 26 CFR 1.1014-1 – Basis of Property Acquired From a Decedent
Refusing an Inheritance
Heirs are not forced to accept. You can formally disclaim all or part of what you would otherwise receive. The most common reason is tax planning: by disclaiming, the property may pass to someone in a lower tax bracket or skip a generation. Other reasons include wanting to keep inherited assets out of reach of creditors or simply preferring that the property go to the next person in line.
To be treated as a qualified disclaimer for federal tax purposes, you must put the disclaimer in writing, deliver it within nine months of the decedent’s death, and not have already accepted any benefit from the property. You also cannot direct where the disclaimed property goes; it passes to whoever would have received it if you had died before the decedent.5eCFR. 26 CFR 25.2518-2 – Requirements for a Qualified Disclaimer Miss the nine-month window and the disclaimer does not qualify. You are treated as having received the property and then given it away, with potential gift tax consequences.
