A child is not automatically entitled to an inheritance from a parent. In almost every state, parents are free to distribute their property however they want, and that includes leaving an adult child nothing at all. Whether a child actually receives anything depends on three things: whether the parent left a valid will, what kinds of assets the parent owned, and how old the child was when the parent died.
When the Parent Left a Will
A valid will controls the estate, and the executor has to follow it. If the will names a child as a beneficiary, that child receives whatever the parent assigned — a specific item, a dollar amount, or a percentage share. The probate court enforces the will; it does not second-guess the parent’s choices.
That same freedom cuts the other way. Testamentary freedom is the foundation of American inheritance law, and it lets a parent intentionally exclude any adult child. For the exclusion to hold, the will has to make the intent unmistakable. Simply leaving a child’s name off the document creates ambiguity, and a probate court may read that silence as an oversight rather than a choice. Parents who want to disinherit a child typically either leave a nominal amount (a dollar is common) or include a clear written statement that the child was considered and intentionally excluded. Both approaches close the door on an “I was forgotten” argument.
Louisiana is the one state that limits this freedom. Its forced heirship laws guarantee a share of the estate to children under 24 and to permanently disabled children of any age, regardless of what the will says. One qualifying child receives 25 percent of the estate; two or more share 50 percent. Nowhere else in the country are parents required to leave anything to their children.
When the Parent Died Without a Will
When a parent dies without a will, state intestacy law supplies the formula. These statutes put close family at the front of the line, and children sit near the top alongside the surviving spouse.1Legal Information Institute. Intestate Succession
The exact division between a spouse and children varies by state, but the pattern is consistent: children inherit either a share alongside the surviving spouse or the entire estate when there is no spouse. If the parent had no spouse and no children, the estate typically moves out to grandchildren, then the parent’s own parents, then siblings.1Legal Information Institute. Intestate Succession
Who counts as a “child” for intestacy matters. Biological and legally adopted children qualify. Children born outside of marriage can inherit if parentage has been established, whether through a court order, a voluntary acknowledgment, or genetic testing. Stepchildren and foster children have no automatic inheritance rights unless the deceased legally adopted them.
One point that surprises families: the estate pays the parent’s debts before distributing anything to heirs. If the parent owed more than they owned, the children may inherit nothing. They do not inherit the debt itself, though — creditors can pursue the estate, not the children personally.
Children Left Out of a Will by Accident
Most states have a pretermitted heir rule that protects children who were apparently left out of a will by mistake rather than design. The textbook example is a parent who signs a will, later has or adopts another child, and never updates the document.2Legal Information Institute. Pretermitted Heir
A child who qualifies as a pretermitted heir generally receives the share they would have gotten if the parent had died without a will. Some states limit the protection to children born after the will was signed; others extend it to any omitted child, including those already alive when the will was written.2Legal Information Institute. Pretermitted Heir
The rule has clear limits. It does not apply if the will itself shows the omission was intentional, if the parent left substantially all of the estate to the surviving spouse, or if the parent provided for the child outside the will — through a trust, life insurance, or lifetime gifts — with evidence that the outside arrangement was meant to stand in for a bequest.2Legal Information Institute.

Assets That Pass Outside the Will
A will only governs assets that go through probate, and many of the most valuable things a parent owns never touch probate. These non-probate assets move directly to a named beneficiary or co-owner no matter what the will says. This is where expectations and reality diverge most often.
The common non-probate assets include:
- Life insurance policies, which pay out to whoever the policyholder named as beneficiary
- Retirement accounts such as 401(k)s, IRAs, and pensions, which have their own beneficiary forms
- Payable-on-death and transfer-on-death accounts, including bank accounts, brokerage accounts, and, in some states, real estate held under a TOD deed
- Jointly owned property, where real estate or financial accounts held in joint tenancy with right of survivorship pass to the surviving co-owner
- Revocable living trusts, where assets placed in the trust during life are distributed under the trust’s terms rather than the will
Whenever one of these has a named beneficiary, that designation controls. A will can say “everything to my three children equally,” but if a $500,000 life insurance policy names only one of them, that one child receives the full payout. The institution holding the asset follows the beneficiary form. The practical result is that a child who was cut out of a parent’s will but named on retirement accounts or policies can end up inheriting more than the children named in the will.
The reverse is also true. If a parent moved most of their wealth into a revocable living trust, the will may control very little of what the parent actually owned. For a child expecting to inherit through the will, the trust’s terms are the ones that matter.
Extra Protection for Minor Children
Adult children can be disinherited in nearly every state. Minor children get meaningful additional protection, so that even when a will leaves everything to someone else, dependent children usually receive some immediate support.
Probate Allowances
Most states let the probate court set aside part of the estate for the surviving family’s immediate needs before creditors or beneficiaries are paid. The two common forms are a family allowance, which supplies money from the estate to support a surviving spouse and dependent children during administration, and an exempt property allowance, which reserves certain personal property or a fixed dollar amount for the family. Both take priority over almost all claims against the estate, ranking just behind administrative costs and funeral expenses. A parent who tries to disinherit a minor child generally cannot override these allowances.
Social Security Survivor Benefits
Separate from the estate entirely, a child may qualify for Social Security survivor benefits if the deceased parent had enough work history. Each eligible child can receive roughly 75 percent of the parent’s benefit amount.3Social Security Administration. What You Could Get From Survivor Benefits Benefits generally run until the child turns 18, or up to 19 if the child is still in high school full-time. A child who became disabled before age 22 can receive survivor benefits at any age.4Social Security Administration. Social Security Benefits for Children After the Death of a Parent
These benefits are not part of the estate. They are unaffected by the parent’s will, debts, or probate proceedings. For families where the parent had modest assets, survivor benefits often provide more financial support than the inheritance itself.
Challenging a Will
A child who was disinherited or who received less than expected can contest the will in probate court. A contest requires more than disagreement with the parent’s decisions. It requires evidence that something was wrong with how the will was created. Courts start from the presumption that a properly executed will is valid, and the challenger carries the burden of proving otherwise.
The recognized grounds are:
- Lack of mental capacity, meaning the parent did not understand what they owned, who their family was, or what the will would do
- Undue influence, meaning someone coerced or manipulated the parent into creating or changing the will
- Fraud, meaning the parent was deceived about the contents or nature of the document they signed
- Improper execution, meaning the will was not signed or witnessed according to the state’s requirements
Undue influence claims are the most common and the hardest to prove, because the coercion almost always happens in private. Courts look at circumstantial patterns, such as a sudden change late in life, growing isolation from family, or a new figure with unusual access to the parent. When someone in a position of trust (a caregiver or a financial advisor, for example) receives a disproportionate share, some courts shift the burden and require that person to prove they did not exert improper influence.
No-Contest Clauses
Some wills include a no-contest clause that revokes the inheritance of any beneficiary who challenges the will. A beneficiary named for $50,000 who files a contest risks losing that $50,000 entirely, even if the concerns were legitimate.5Legal Information Institute. In Terrorem Clause
Most states enforce these clauses, but a majority recognize an exception for probable cause, meaning reasonable grounds to believe the challenge would succeed. A couple of states refuse to enforce no-contest clauses at all on public policy grounds.5Legal Information Institute. In Terrorem Clause A child who was left nothing has nothing to forfeit; the clause only bites when there is something at stake.
Deadlines for Filing
Every state sets a deadline for contesting a will, and the windows are short. Most states allow somewhere between three months and one year after the will is admitted to probate, though a few give longer. Missing the deadline permanently forfeits the right to challenge, no matter how strong the underlying case. Anyone considering a contest should talk to a probate attorney well before the window closes.
