In every state except Louisiana, you can disinherit a child from your will, and you do not need a reason. What you do need is a will that names the child and states plainly that the omission is intentional, plus a matching sweep of every account and policy that passes outside probate. Skip either half and the disinheritance can quietly fail.
Name the Child and Say It Was Intentional
The single most important step is to identify the child you want to exclude and state clearly that the exclusion is deliberate. A sentence such as “I intentionally make no provision for my son, John Doe, or his descendants” removes the ambiguity a court would otherwise have to resolve. Leaving a child’s name out of the will entirely is where most disinheritance plans fall apart.
The reason is a category of laws called pretermitted heir statutes, which exist in some form in most states. They were written to protect children accidentally left out of a will, particularly children born after the will was signed. If a court finds a child was simply not mentioned, it can award that child the share they would have received if there were no will at all. Some states apply this only to children born after execution; others extend it to any child the document fails to name.
You may have heard that leaving a child one dollar accomplishes the same thing. It can work, because it shows the child wasn’t forgotten. But explicit disinheritance language is cleaner and avoids the small administrative task of actually distributing that dollar. What the will has to demonstrate is that you knew the child existed and chose to leave them nothing.
Some estate planning attorneys suggest a brief, separate letter explaining your reasons. The letter is not legally binding, but it can serve as evidence of your state of mind if the will is later challenged. Keep it factual and measured. An angry letter listing grievances can backfire by suggesting you were acting from temporary emotion rather than settled judgment.
Assets Your Will Does Not Control
This is where disinheritance plans most often fail in practice. A will only governs property that passes through probate. Several major categories of assets bypass your will entirely and go to whoever is named on the account, whatever your will says.
- Retirement accounts. 401(k) plans, IRAs, pensions, and similar accounts pass to whoever is listed on the beneficiary designation form. Under federal law, plan administrators look only at the plan documents and the beneficiary on file when deciding who gets paid. If your child is the named beneficiary on your 401(k), they receive it even if your will explicitly disinherits them.1Office of the Law Revision Counsel. 29 U.S. Code 1144 – Other Laws
- Life insurance policies. The beneficiary designation on the policy controls. Disinherit a child in your will but forget to change the insurance beneficiary, and the insurer will pay the child.
- Jointly held property. Real estate or bank accounts held in joint tenancy with right of survivorship pass automatically to the surviving co-owner. A will cannot override this.
- Transfer-on-death and payable-on-death accounts. Bank accounts, brokerage accounts, and, in some states, real estate can carry a TOD or POD designation that overrides anything in a will.
If you intend to disinherit a child, audit every account and policy you own and confirm the child is not named on any of them. This is a separate project from writing your will, and skipping it can undo everything the will was designed to accomplish.
Louisiana and Minor Children: The Two Boundaries
Two situations sit outside the general rule that adult children have no automatic right to inherit.
Louisiana is the only state that restricts a parent’s right to disinherit certain children. Under its forced heirship rules, children under 24 at the time of the parent’s death, and children of any age with a permanent mental or physical disability that prevents them from caring for themselves, are entitled to a minimum share of the estate.2Justia. Louisiana Civil Code Article 1493 – Forced Heirs; Representation of Forced Heirs These children are called forced heirs. Louisiana does allow disinheritance of a forced heir, but only for specific causes named in the Civil Code, and the disinheriting document must state the reason. If you live in Louisiana and have a child who might qualify as a forced heir, this is a conversation for a Louisiana attorney rather than a template will.
Minor children are the other boundary, and it applies everywhere. A parent cannot use a will to escape all financial responsibility to a child who is still a minor. Most states provide a family allowance that gives minor children access to a portion of the estate during probate to fill the support gap while the estate is settled, and the allowance generally cannot be blocked by the terms of a will. Social Security survivor benefits sit on top of that: if a parent paid into the system, unmarried children under 18 are eligible for payments based on the parent’s record, and a will or trust has no effect on those payments.3Social Security Administration.

Don’t Accidentally Leave It to the Grandchildren
Disinheriting a child does not automatically disinherit that child’s children. Every state has an anti-lapse statute that can redirect a deceased beneficiary’s share to their descendants rather than letting it fall back into the estate. The statutes were written to carry out what the law assumes you would have wanted, but they can produce results you never intended.
The risk is subtle when disinheritance is involved. If you disinherit your daughter but say nothing about her children, and your daughter dies before you do, a court applying anti-lapse principles might conclude the grandchildren should take what their mother would have received. The outcome depends on how your state’s statute is written and how specifically your will addresses the possibility.
The safer approach is to be explicit. Language such as “I intentionally make no provision for my daughter, Jane Doe, or any of her descendants” closes the gap. If you actually want your grandchildren to inherit even though you are disinheriting their parent, name them as beneficiaries separately. Leaving the question open invites litigation.
Should You Use a Trust Instead
A revocable living trust offers two practical advantages over a will when disinheritance is the goal: privacy and a higher barrier to challenges.
A will becomes a public document once it enters probate. Anyone can read it, including the disinherited child, who will see exactly what was left and to whom. A trust does not go through probate. Its contents stay private, which can reduce the emotional triggers that lead to litigation. In some cases, a disinherited child may not even know the full scope of what they were excluded from.
Contesting a trust is also harder. The grounds are largely the same, but there is no probate proceeding to latch onto, and the trust was administered by the person who created it during their lifetime, which provides a running record of competence and intent that a one-time will signing does not.
A trust does not replace clear disinheritance language. The same explicit statement belongs in the trust document. And if you have both a will and a trust, the disinheritance language must match across both. Conflicting instructions give a disinherited child exactly the ambiguity they need to mount a challenge.
What a Contest Looks Like
A child who is cut out cannot challenge the will simply because the result feels unfair. They have to attack the legal validity of the document. If they succeed, the will is thrown out and the estate passes under the state’s default inheritance rules, which typically include all children equally. The recognized grounds are:
- Lack of mental capacity. The challenger argues the parent did not understand what they were signing, did not know what property they owned, or could not identify the people who would normally inherit from them. A dementia diagnosis alone is not enough; the question is capacity at the specific moment of signing.
- Undue influence. Someone in a position of trust, such as a caregiver, new spouse, or favored child, pressured or manipulated the parent into changing the will. Courts look for isolation of the parent, involvement of the influencer in drafting, and a distribution that suspiciously favors the influencer.
- Fraud or forgery. The parent was tricked into signing a document they believed was something else, was given false information to induce the change, or the signature is not genuine.
- Improper execution. The will was not signed or witnessed according to state law. Most states require the parent’s signature in the presence of two witnesses, who must also sign.
Deadlines for filing vary by state, typically between three months and two years after the will is admitted to probate. Missing the deadline forfeits the right to contest, however strong the grounds.
No-Contest Clauses
A no-contest clause, sometimes called an in terrorem clause, strips a beneficiary of their inheritance if they challenge the will and lose. The idea is to make litigation financially risky by forcing the child to weigh a guaranteed smaller inheritance against the chance of winning a larger one in court.
For the clause to have any teeth, the disinherited child must actually be left something. A child who receives nothing has nothing to lose by filing, so the clause creates no deterrent. This is why many attorneys advise leaving a modest but meaningful bequest to a child you want to disinherit, just large enough that forfeiting it would sting.
Enforceability varies. Most states that enforce these clauses carve out an exception for challenges brought in good faith with probable cause, so a child with credible evidence of forgery or undue influence can proceed without triggering forfeiture. Florida takes the strongest position in the other direction, declaring no-contest clauses in wills completely unenforceable regardless of the circumstances.4The Florida Legislature. Florida Statutes 732.517 – Penalty Clause for Contest If you’re relying on this kind of clause, confirm your state actually enforces it.
A no-contest clause discourages challenges; it does not prevent them. The real protection comes from clear disinheritance language, consistent beneficiary designations on every account and policy, and a document that was properly signed and witnessed while you were clearly competent.
