Quick answer: Yes, in 49 of 50 US states you can legally disinherit an adult child — but simply leaving their name out of your will is not enough. You must name the child explicitly and state that the exclusion is intentional, then remove them from every beneficiary designation (retirement accounts, life insurance, payable-on-death accounts) that bypasses your will. Miss either step and the child can still inherit: an unnamed child may win a share as a "pretermitted heir," and a named beneficiary on an IRA or life insurance policy receives that money no matter what your will says. Louisiana is the one exception, where children under 24 (and permanently disabled children of any age) are "forced heirs" who cannot be fully disinherited.
What "Disinherit" Actually Means
To disinherit a child means to deliberately exclude them from inheriting any part of your estate. It is a legal act, not a family gesture — and the law treats it very differently from simply forgetting someone.
There are three ways people try to exclude a child, and only one of them works reliably:
| Method | What it does | Does it work? |
|---|---|---|
| Omitting the child entirely | The will never mentions them | No — courts presume the omission was a mistake |
| Naming the child and giving them $0 | The will names them and states they receive nothing | Yes — the standard, legally recognized method |
| Leaving a token gift ($1 or a small sum) | The will names them and leaves a small amount | Yes — proves intent and can make a no-contest clause enforceable |
The core rule is simple: your will must prove you knew the child existed and chose to leave them nothing. Silence proves nothing. A court looking at a will that never mentions a child will usually assume the parent forgot, made an error, or wrote the will before the child was born — and in most states, that assumption hands the child a share of the estate anyway.
Disinheritance is also different from giving a child less than their siblings. Leaving one child 10% and another 90% is not disinheritance — it is unequal distribution, and it needs no special language at all. The special rules in this guide apply only when a child receives nothing.
Can You Legally Disinherit a Child?
In almost every state, yes — with limits that depend on the child's age and your state.
| Person | Can you fully disinherit them? | What protects them |
|---|---|---|
| Adult child (18 or older) | Yes, in 49 states | Pretermitted heir statutes — you must name them and state the exclusion is intentional |
| Minor child (under 18) | No | No state lets you disinherit a minor child; they receive their intestate share regardless of what the will says |
| Child under 24 in Louisiana | No | Louisiana forced heirship (La. Civ. Code art. 1493) |
| Permanently disabled child in Louisiana | No | Louisiana forced heirship, any age |
| Adult child in Louisiana | Yes, with limits | Forced heirship does not apply, but only for the specific "just cause" reasons in the Civil Code |
| After-born child (born after the will is signed) | Not automatically | Pretermitted heir statutes in every state — update the will or use forward-looking language |
| Stepchild (never legally adopted) | Yes | Stepchildren have no inheritance rights unless named as beneficiaries |
| Estranged adult child | Yes | Estrangement changes nothing legally — the same explicit-language rule applies |
Two points surprise most people. First, you do not need a reason, and you do not need to prove one. No state requires you to justify disinheriting an adult child, and you do not have to explain yourself in the will. Second, an adult child has no automatic right to inherit from a parent in American law. Your property is yours to distribute as you choose — the law only demands that your choice be unmistakable.

Wills, trusts, and inheritance rules vary by state, and a mistake can cost your family years in probate court. Have an estate planning attorney in your state review your documents before you sign them.
The Two-Layer Rule: Why Most Disinheritances Partially Fail
This is the single biggest reason disinheritances fail in practice — and the point most online guides skip entirely. Your estate passes through two legally separate channels, and your will only controls one of them.
Layer 1 — Testamentary assets pass through probate, where your will governs. These are assets held in your name alone with no beneficiary designation: a house titled only to you, a personal bank account with no payable-on-death designation, a car, personal property, and a brokerage account with no transfer-on-death election.
Layer 2 — Non-testamentary assets pass entirely outside your will. IRAs and 401(k)s, life insurance death benefits, accounts with payable-on-death (POD) or transfer-on-death (TOD) designations, jointly titled real estate, and assets already held in a living trust. A beneficiary designation form — often filled out once, decades ago, and never updated — legally controls these assets. Your will cannot override it.
A worked example of how disinheritance breaks down
Imagine Sandra, who has a $500,000 estate and a serious falling-out with her son Marcus. She updates her will with clear disinheritance language — but she never touches her beneficiary designations:
| Asset | Value | How it passes | Who receives it |
|---|---|---|---|
| IRA (Marcus named as beneficiary) | $180,000 | Beneficiary designation — bypasses the will | Marcus |
| Life insurance (Marcus named) | $70,000 | Beneficiary designation — bypasses the will | Marcus |
| Home (her name alone) | $200,000 | Probate — the will controls | Daughter Priya |
| Savings account (no POD) | $50,000 | Probate — the will controls | Daughter Priya |
Result: Marcus receives $250,000 — half the estate — despite unambiguous disinheritance language in the will. The will successfully disinherited him only from the probate half. Updating the IRA and life insurance beneficiary designations to Priya — a 20-minute task — would have changed the outcome completely.
The practical rule: after you update your will, pull every account statement and insurance policy, identify the named beneficiary on each one, and change any that still list the person you are disinheriting. Then check again after every major life event — a new job, a new bank account, a refinanced mortgage, a divorce. If your marriage is ending, sorting out the paperwork matters on both sides: see what happens if your spouse won't sign divorce papers, because an unfinished divorce leaves beneficiary designations and joint titles exactly where they are.
How to Disinherit a Child in a Will: 7 Steps
Follow these steps in order. Each one closes a different gap that a disinherited child — or their lawyer — could use to challenge your wishes.
Step 1: Name the child completely
Use the child's full legal name, date of birth, and relationship to you. Never rely on a role alone ("my eldest son"), because family structures change and roles are ambiguous. A court must be able to identify exactly who you mean, with no room for argument.
Step 2: State the exclusion in plain, affirmative language
This is the heart of the disinheritance. The clause should do four things: identify the person, state the relationship, declare the exclusion intentional, and confirm no other provision exists for them elsewhere. A standard example:
"I intentionally and with full knowledge make no provision in this Will for my son, [Full Legal Name], born [Date], and it is my intent that he receive no part of my estate, whether by bequest, devise, or intestate succession."
Two details matter here. First, the words "intentionally" and "with full knowledge" are what defeat a pretermitted heir claim — they prove the omission was deliberate. Second, the phrase "or intestate succession" closes the gap if part of your estate somehow passes outside the will's instructions.
Step 3: Do not put your reasons in the will
You are not legally required to explain why you are disinheriting a child, and putting a reason in the will usually hurts you. A stated reason introduces a factual dispute: the disinherited child can argue the reason is false and use that to claim you lacked mental capacity or were unduly influenced. Angry or accusatory language in a will becomes part of the public probate record and can even amount to testamentary libel.
If you want to explain yourself, write a separate personal letter, store it with your will but never attach it to the will, and instruct your executor to share it after your death. The letter is not legally binding, but it can reduce the emotional shock for the family and lower the motivation to litigate.
Step 4: Update every beneficiary designation at the same time
This is the two-layer rule from above, applied immediately. Log into every retirement account, insurance portal, and bank account with a POD designation, and change the named beneficiary. Also check:
- Employer retirement plans (401(k), 403(b), pensions) — these often have their own beneficiary forms, separate from your will
- Life insurance policies, including any through your employer
- Bank and credit union POD/TOD accounts
- Brokerage TOD accounts
- Real estate held in joint tenancy with right of survivorship — remove the child as a joint owner and retitle the property if you want to exclude them
- Health savings accounts and annuities with named beneficiaries
Step 5: Add a no-contest clause — and understand its limits
A no-contest clause (also called an in terrorem clause) says that any beneficiary who challenges the will forfeits whatever they were left. It is a deterrent, not a guarantee — and against a fully disinherited child, it has a built-in weakness: a person who receives nothing has nothing to lose by contesting.
That is why many estate attorneys pair the clause with a modest bequest — $5,000 to $25,000, for example — given to the child specifically so the no-contest clause has teeth. The child must then weigh a guaranteed gift against the risk and cost of litigating. Whether this strategy fits your situation depends on your state and your family dynamics; it is worth discussing with your attorney.
No-contest clauses are not enforceable everywhere:
| State | No-contest clause enforced? | Standard |
|---|---|---|
| New York | Yes — strictly | No probable-cause defense; N.Y. EPTL § 3-3.5 |
| Nevada | Yes — strictly | Enforced to the greatest extent possible; NRS 137.005 |
| California | Yes — limited | Only triggers if the challenge lacked probable cause; Cal. Prob. Code §§ 21310–21315 |
| Texas | Yes — limited | Challenger must show just cause and good faith |
| Florida | No | Unenforceable by statute; Fla. Stat. § 732.517 |
| Indiana | No | Rejected entirely |
Step 6: Execute the will correctly for your state
A perfectly worded disinheritance clause is worthless in an improperly executed will. Every state requires at least two witnesses who are present when you sign, and most require that the witnesses not be beneficiaries. Several states permit a self-proving affidavit — a notarized statement signed by you and your witnesses — which speeds up probate and reduces the chance of a signature challenge. Use it if your state allows it.
Step 7: Revoke prior wills explicitly and review after every life event
Your new will should state: "I revoke all prior wills and codicils." Then destroy the physical copies of the old document — an old will floating around is an invitation to a challenge.
Then set a habit: review your estate plan after every birth, adoption, marriage, divorce, death in the family, or major asset change. A child born after your will is signed is the most dangerous gap of all, as the next section explains.
The Pretermitted Heir Trap: Children Born After You Sign
Every state protects children who were born or adopted after the will was executed and were not mentioned in it. These children are called pretermitted heirs, and the law presumes you would have provided for them if you had known they existed. If a court finds a child was simply not mentioned, it can award that child the share they would have received if you had died without a will at all.
The protection exists in some form in most states, including:
| State | Pretermitted heir statute |
|---|---|
| California | Cal. Prob. Code § 21621 |
| Florida | Fla. Stat. § 732.302 |
| Pennsylvania | 20 Pa.C.S. § 2507 |
| New York | N.Y. EPTL § 5-3.2 |
| Texas | Tex. Est. Code § 255.053 |
The fix is straightforward: include forward-looking exclusion language that covers children not yet born or adopted when you sign. For example:
"I intentionally make no provision for any child or descendant not specifically named in this will, including any child born or adopted after the execution of this will."
Even with that language, the safest practice is to update or re-execute your will after any birth or adoption, so the disinheritance clearly reflects your current family.
Louisiana: The One State Where You (Usually) Cannot Disinherit a Child
Louisiana is the only state with forced heirship. Under Louisiana Civil Code Article 1493, children who are under 24 years old at the time of the parent's death — or children of any age who are permanently mentally or physically disabled and unable to care for themselves — are "forced heirs" entitled to a minimum share of the estate. A parent cannot simply write them out of a will.
| Situation in Louisiana | Can the child be disinherited? |
|---|---|
| Child under 24 at parent's death | No — forced heir, entitled to a minimum share |
| Permanently disabled child, any age | No — forced heir |
| Adult child (24+), not disabled | Yes, but only for a "just cause" listed in the Civil Code |
| Child who struck or attempted to kill a parent | Yes — just cause under La. Civ. Code art. 1621 |
| Child convicted of a crime punishable by life imprisonment or death | Yes — just cause |
| Child who committed cruel treatment toward a parent | Yes — just cause |
| Child who failed to communicate with a parent for 2 years after reaching adulthood | Yes — just cause, if without reasonable justification |
If you live in Louisiana — or own property there — get local legal advice before attempting any disinheritance. The rules are genuinely different from the other 49 states.
Will vs. Trust: Which Tool Makes Disinheritance Stick?
A will is the standard tool for disinheriting a child, but a revocable living trust has two practical advantages when disinheritance is the goal: privacy and a higher barrier to legal challenges. A will goes through probate, which is a public court process — anyone can read it, including the disinherited child. A trust stays out of probate and out of public view.
| Factor | Will | Revocable living trust |
|---|---|---|
| Public record? | Yes — probate is public | No — stays private |
| Easier to challenge? | Yes — probate court, lower bar | Harder — no probate, higher bar |
| Controls non-probate assets? | No | Yes, for assets transferred into the trust |
| Cost to set up | Lower | Higher |
| Needs a pour-over will too? | n/a | Yes — for assets left outside the trust |
One critical detail: you must specifically disinherit the child in the pour-over will that accompanies your trust. If the trust document reflects the disinheritance but the pour-over will does not, assets that fall into the will can still reach the child. Both documents must tell the same story. If you already own a home in a trust, the mechanics of moving property into one are the same as those in our guide to putting a house in a trust in Texas — the trust, not the will, controls whatever it holds.
Common Mistakes That Undo a Disinheritance
Most failed disinheritances fail on paperwork, not on the law. Avoid these:
| Mistake | Why it breaks the plan |
|---|---|
| Crossing out a name or writing in the margins | Handwritten changes to a signed will are invalid in most states and can invalidate the whole document — always execute a new will or a properly witnessed codicil |
| Omitting instead of excluding | Courts presume omissions of children are accidental; pretermitted heir statutes may award them an intestate share |
| Writing an inflammatory reason in the will | Public accusations become part of the probate record, may be testamentary libel, and hand the child a capacity or undue-influence argument |
| Forgetting joint account holders | A joint tenancy with right of survivorship passes to the surviving owner automatically, regardless of your will |
| Not updating after major life events | A child born after the will is signed may claim a pretermitted heir share unless the will has forward-looking language |
| Relying only on a will when trust assets are involved | If assets sit in an irrevocable trust, the will cannot reach them — the trust document must independently reflect the disinheritance |
| Leaving a gap in the residuary clause | If any part of the estate passes by intestacy because the will fails to cover it, the disinherited child can inherit that part — always include a residuary clause disposing of the entire estate |
How a Disinherited Child Can Challenge the Will
A disinherited child has standing to contest the will. They cannot win simply because they were left out — they must prove a legal ground. The common grounds:
| Ground | What the child must prove |
|---|---|
| Lack of testamentary capacity | You did not understand what you were signing, the nature of your property, or who your natural heirs were |
| Undue influence | Someone else pressured or manipulated you into the disinheritance |
| Fraud | You were deceived about the contents of the document you signed |
| Improper execution | The will was not signed or witnessed according to your state's formalities |
| Mistake / pretermitted heir | The omission was accidental — the child was not mentioned, or was born after the will was signed |
| Forgery | The signature or the document itself is not genuine |
Three steps reduce contest risk more than anything else: have the will drafted and executed with professional involvement, execute it while you are clearly healthy and competent (not during a serious illness), and keep a capacity letter from your physician dated around the time of execution. A contemporaneous record that you signed knowingly and voluntarily is the strongest evidence there is.
Do You Need a Lawyer to Disinherit a Child?
Strictly speaking, no — you can write the clause yourself. But disinheritance is one of the situations where professional help pays for itself. A contested will can cost the estate tens of thousands of dollars in legal fees and take a year or more in probate court, and most contests attack exactly the points this guide covers: ambiguous language, missing beneficiary updates, and sloppy execution.
A reasonable approach for most families:
- Simple situation (one adult child, no Louisiana connection, modest estate): a guided online will platform plus an attorney review of the finished document.
- Complex situation (blended family, business assets, property in multiple states, a disabled child, or Louisiana residency): an estate planning attorney from the start.
- Already expecting a challenge: an attorney, a capacity letter from your physician, a self-proving affidavit, and a trust instead of — or in addition to — a will.
Whichever route you take, the documents are only half the job. The other half is the audit: every beneficiary designation, every joint title, every POD account, checked and updated to match the will.
Frequently Asked Questions
Can I disinherit my child in my will?
Yes, in 49 of 50 states you can disinherit an adult child. You must name the child explicitly in the will and state that the exclusion is intentional — simply leaving them out is not enough, because courts may treat an unnamed child as accidentally omitted (a pretermitted heir) and award them a share. Louisiana is the exception: children under 24 and permanently disabled children are forced heirs who cannot be fully disinherited.
Can I disinherit a minor child?
No. No US state permits disinheriting a child under 18. Even if your will states the exclusion clearly, a minor child still receives the share they would have inherited under your state's intestate succession laws. Child support obligations can also survive death in some states, which is separate from inheritance.
What happens if I just leave my child out of my will?
A court will usually presume the omission was a mistake. Under pretermitted heir statutes, which exist in most states, an unnamed child can be awarded the share they would have received if you had died without a will. The only reliable fix is explicit language naming the child and stating the exclusion is intentional.
What wording should I use to disinherit a child?
A standard clause reads: "I intentionally and with full knowledge make no provision in this Will for my son/daughter, [Full Legal Name], born [Date], and it is my intent that he/she receive no part of my estate, whether by bequest, devise, or intestate succession." Use the child's full legal name and date of birth, and add forward-looking language covering children born or adopted after the will is signed.
Does a will override a life insurance beneficiary?
No. Life insurance, IRAs, 401(k)s, and payable-on-death accounts pass by beneficiary designation and completely bypass your will. If your child is still named as the beneficiary on any of these, they will receive that money no matter what your will says. You must update every beneficiary designation separately.
Can I disinherit a child and leave everything to charity?
Yes. In 49 states you can leave your entire estate to charity, to one child, or to anyone else, as long as the disinheritance language is explicit. The same rules apply: name the excluded child, state the exclusion is intentional, and audit all beneficiary designations. Louisiana's forced heirship rules are the exception.
What is a no-contest clause, and does it stop a disinherited child from suing?
A no-contest clause (in terrorem clause) says a beneficiary who challenges the will forfeits their inheritance. It only deters someone who has something to lose — a fully disinherited child has nothing to forfeit, so the clause has no teeth against them. The common workaround is leaving the child a modest bequest ($5,000–$25,000) paired with the clause. No-contest clauses are unenforceable in Florida and Indiana.
Can a disinherited child still contest the will?
Yes. A disinherited child has standing to contest on grounds like lack of capacity, undue influence, fraud, improper execution, or pretermitted heir status. They cannot win just because they were left out — they must prove one of those grounds. Professional drafting, a self-proving affidavit, and a physician's capacity letter are the best defenses.
Can I disinherit my child in a trust instead of a will?
Yes, and a revocable living trust has advantages: it stays private (no public probate), and it is harder to challenge than a will. But the trust must hold the assets for this to work, and you still need a pour-over will that specifically disinherits the child for any assets left outside the trust.
Should I tell my child I am disinheriting them?
There is no legal requirement to tell them, and many attorneys advise against putting reasons in the will itself. A separate, private letter explaining your decision — stored with the will, not attached to it — can reduce shock and litigation risk. Whether to have the conversation in person is a family decision, not a legal one; consider it carefully, because it often determines whether the will is contested at all.
The Bottom Line
Disinheriting a child in a will comes down to two layers, done together: explicit language in the will naming the child and declaring the exclusion intentional, and a full audit of every beneficiary designation and joint title that bypasses the will. Add a no-contest clause (with a modest bequest if you want it to bite), execute the will properly with a self-proving affidavit, revoke all prior wills, and review everything after every major life event. Louisiana residents face genuinely different rules and should get local advice. Done correctly, your wishes will hold up in court; done halfway, the will says one thing and the money goes somewhere else entirely.
