A legal heir is a person entitled to receive property from someone who has died. If the deceased left a valid will, the heirs are the people (or charities, or trusts) named in it. If there is no valid will, state intestate succession law decides, and the line starts with the surviving spouse and children before moving outward to parents, siblings, and more distant relatives.1Legal Information Institute. Intestate Succession Who actually inherits, and how much, also depends on what kind of asset is involved, because a large share of most estates never passes through the will at all.
Who Qualifies as a Legal Heir When There Is a Will
A valid will gives the person who made it (the testator) broad freedom to leave property to almost anyone: a spouse, children, friends, charities, or a trust. The testator must be at least 18 and have the mental capacity to understand what they own, who their family members are, and what the will is doing with their property.2Justia. Preparing a Legally Valid Will The will must be written, signed, and witnessed, usually by two disinterested people, meaning witnesses who do not themselves stand to inherit under it. In some states, a witness who is also a beneficiary doesn’t void the will but may forfeit their own gift.
One point trips up most families: a will only governs assets titled in the deceased person’s name alone. Jointly held property, retirement accounts, and life insurance pass under separate rules, which are covered further down.
The Spouse’s Guaranteed Share
A will cannot fully disinherit a surviving spouse in most states. Separate-property states protect the spouse through what’s called an elective share or forced share, which typically guarantees roughly one-third of the probate estate regardless of what the will says.3Legal Information Institute. Elective Share The spouse has to actively claim it instead of accepting what the will provides.
Community property states handle this differently. Each spouse already owns half of everything earned during the marriage, so the survivor keeps that half automatically. The elective share also generally reaches only probate assets, not property held in trusts, retirement accounts with named beneficiaries, or assets owned jointly with someone other than the spouse.
Who Inherits When There Is No Will
When someone dies without a valid will, state intestate succession law supplies a default heir list. The rules vary by state, but the sequence is consistent: spouse and children first, then parents, then siblings and their descendants, then grandparents, aunts, uncles, and cousins.1Legal Information Institute. Intestate Succession
A surviving spouse normally takes the largest share. With no children, the spouse often inherits everything. When both a spouse and children survive, the estate is divided between them in shares that depend on the state. In community property states, the surviving spouse already owns half the marital property; intestate rules apply only to the deceased’s separate property and their half of the community assets.
If no spouse or children survive, parents are next, then siblings and their children, and so on. Only when no living relative can be found at all does property escheat to the state, and courts search extensively for heirs before that happens.
How Family Status Changes the Answer
Adopted Children and Stepchildren
Adopted children inherit from their adoptive parents on the same footing as biological children. Once an adoption is finalized, the adopted child generally loses intestate inheritance rights from the biological parents, with narrow exceptions in a handful of states.4Social Security Administration. POMS GN 00306170 – State Laws on the Right of Adopted Child to Inherit From Natural Parent When a stepparent adopts and the other biological parent is still living, the child can typically still inherit from the non-adopting biological parent.
Stepchildren who were never legally adopted have no automatic intestate right to inherit from a stepparent. A stepparent who wants a stepchild to inherit has to name them in a will or other estate document.
Half-Siblings
Half-siblings, who share one biological parent, generally inherit in the same tier as full siblings. A small number of states give them a reduced share when both compete for the same estate.
Children Born Outside of Marriage
A child born outside of marriage has the same inheritance rights as any other child, as long as legal parentage is established. For mothers, the birth itself does that. For fathers, parentage may need a birth certificate listing the father, a court order, genetic testing, or a voluntary acknowledgment of paternity. Without that link, a child may have no claim under intestate succession, especially if the father died without a will. Some states allow posthumous paternity claims, often requiring DNA from the deceased or close relatives.
Posthumous Children
A child conceived before a parent’s death but born afterward is treated like any child already living at the parent’s death.5Legal Information Institute. Posthumous Child They inherit through intestate succession and can take under a will as part of a class like “my children.” Children conceived after death through assisted reproduction face more complicated rules that vary significantly by state.
Minor Heirs
Children under 18 can inherit, but they can’t manage inherited property directly. A court will usually appoint a guardian or conservator, or the assets can be held under the Uniform Transfers to Minors Act, adopted in some form by every state, which lets a custodian manage property for the child without a formal trust.6Legal Information Institute. Uniform Transfers to Minors Act The custodian holds the assets until the child reaches the age the state sets, usually somewhere between 18 and 25.
Assets That Skip the Will and the Heirs Entirely
Much of a typical estate never touches the will. Life insurance, 401(k)s and IRAs, payable-on-death bank accounts, transfer-on-death brokerage accounts, and annuities all pass straight to whoever is listed on the beneficiary designation form. Property held jointly with a right of survivorship goes automatically to the surviving owner.
If a will leaves a retirement account to one child but the beneficiary form on file names a different child, the financial institution follows its own records, not the will. That is why reviewing beneficiary forms matters as much as drafting the will itself. After a divorce, remarriage, or the birth of a child, an outdated form can send money somewhere the deceased never intended, and no amount of careful will drafting fixes it.
When Someone Loses or Gives Up Their Place
Disinheritance
A will can explicitly exclude someone who would otherwise inherit. Disinheritance overrides the default intestate rules for everyone except a surviving spouse in states with an elective share.7Legal Information Institute. Disinheritance Simply leaving someone out may not be enough; estate planning attorneys usually recommend stating clearly that the omission is intentional, because a court may otherwise assume the person was accidentally overlooked and award them a share.
The Slayer Rule
Someone who intentionally and unlawfully kills another person cannot inherit from the victim. Courts treat the killer as having died first, which removes them from both the will and intestate succession.8Legal Information Institute. Slayer Rule A criminal conviction settles the question, but it isn’t required. The Uniform Probate Code lets a probate court apply the rule on a preponderance of the evidence, a lower standard than criminal law, so an acquittal in criminal court doesn’t necessarily protect an inheritance.
Disclaiming an Inheritance
An heir who doesn’t want an inheritance can formally refuse it through a qualified disclaimer. Done correctly, a disclaimer is treated as though the heir died before the person who left them the property, and the assets then pass to whoever is next in line. Federal law requires the disclaimer to be in writing, delivered within nine months of the death (or nine months after the heir turns 21), and the heir cannot have accepted any benefit from the property or try to direct where it goes instead.9Office of the Law Revision Counsel. 26 USC 2518 – Disclaimer of Certain Property Interests People sometimes disclaim so assets pass directly to grandchildren, or to keep assets out of a creditor’s reach, though courts look closely at disclaimers that look designed to dodge debts.
Advancements
A lifetime gift from a parent to a child can count as an early payment of that child’s inheritance, reducing their later share. Under the Uniform Probate Code, a gift counts as an advancement only if the giver declared it in writing at the time, or the recipient acknowledged it in writing.10Legal Information Institute. Advancement Without that written record, it’s just a gift, and the inheritance share stays the same.
Simultaneous Death
When two people who would inherit from each other die close together, the Uniform Simultaneous Death Act keeps the assets from passing through two separate probate proceedings. If the deaths fall within 120 hours of each other, each person is treated as having died first for inheritance purposes, so the property moves straight to the next heir in line.11Legal Information Institute. Uniform Simultaneous Death Act
Debts Come Before Heirs
Heirs receive nothing until the estate’s debts are settled. The executor or administrator identifies valid creditor claims, pays them from estate assets, and only then distributes what remains. If cash runs short, other assets may be sold. When debts exceed assets, the estate is insolvent, some creditors go unpaid, and heirs may receive nothing at all.
State law sets priority among debts, but funeral expenses, court costs, and taxes generally come ahead of ordinary creditors. Heirs aren’t personally liable for a deceased person’s debts beyond the value of what they inherit, and life insurance proceeds and retirement accounts paid to named beneficiaries are generally shielded from the estate’s creditors.
Most estates owe no federal estate tax. For 2026, the exemption is $15,000,000 per person, with a top rate of 40% on amounts above that.12Internal Revenue Service. What’s New – Estate and Gift Tax A handful of states impose their own estate or inheritance taxes at lower thresholds. The inheritance itself is not federal taxable income to the heir, though distributions from an inherited retirement account can be.
Proving You Are an Heir
Being an heir on paper and actually collecting an inheritance are two different things. In most cases, assets pass through probate, the court-supervised process of validating a will, identifying heirs, paying debts, and distributing what’s left. The executor named in the will, or an administrator appointed by the court when there’s no will, runs it.
The executor must notify known heirs and beneficiaries, and in many jurisdictions must also publish a notice in a local newspaper so unknown creditors and potential heirs can come forward. When heirship is disputed or unclear, the court may require an affidavit of heirship, a sworn statement from someone with personal knowledge of the deceased’s family history. These affidavits usually have to be signed by a disinterested person with no financial stake in the estate.
Many states offer simplified procedures for smaller estates, often those below somewhere between $50,000 and $150,000, which can let heirs collect assets with an affidavit instead of a full probate case. Anyone expecting to inherit, or managing an estate, generally saves money by talking to a probate attorney early rather than untangling problems later.
