New York gives you broad freedom to decide who inherits your property when you die. With one important exception, your surviving spouse, you are not legally required to leave anything to any particular relative, including an adult child. This guide explains how to disinherit a child in New York the right way: which statutes govern, the limits you cannot get around, and the concrete steps that make a disinheritance hold up in Surrogate’s Court.
Can you disinherit a child in New York?
Yes. New York does not have “forced heirship” for children. Unlike Louisiana and some civil-law countries, New York’s Estates, Powers and Trusts Law (EPTL) does not reserve a mandatory share of a parent’s estate for adult children. A competent adult who executes a valid will under EPTL §3-2.1 may leave a child out entirely, and the child has no automatic statutory right to any portion of the estate. This freedom applies whether the child is a minor or an adult, biological or adopted. The only person New York protects from being cut out is a surviving spouse.
The spousal exception: you cannot fully disinherit a spouse (EPTL §5-1.1-A)
This is the single most important New York nuance, and it is frequently confused with disinheriting children. Under EPTL §5-1.1-A, a surviving spouse has a right of election. A spouse who is disinherited, or who is left less than the statutory share, may elect against the will and claim the greater of $50,000 or one-third of the net estate.
The elective share is calculated against the “net elective-share estate,” which includes many non-probate “testamentary substitutes”: Totten trust (in-trust-for) accounts, jointly held accounts, certain lifetime gifts and retained-interest transfers. You therefore generally cannot defeat a spouse’s right of election simply by retitling assets or putting them in a revocable trust. There are limited tools, such as a valid pre- or post-nuptial waiver under EPTL §5-1.1-A(e), but spousal disinheritance is far more constrained than child disinheritance and should never be attempted without counsel. The practical takeaway: a parent can disinherit a child outright, but cannot disinherit a husband or wife without a valid waiver. See our page on the spousal right of election.
Do you have to mention the child in your will?
No. Failing to name a child in your will is not, by itself, grounds to set the will aside in New York. Even so, naming the child and stating that you are intentionally leaving them nothing, rather than silently omitting them, is usually the stronger drafting choice. An express statement closes the door on any argument that the omission was an oversight, and it makes the intent unmistakable to the Surrogate.
The after-born / pretermitted child rule (EPTL §5-3.2)
One trap deserves special attention. Under EPTL §5-3.2, New York protects a child who was born or adopted after the will was executed and who was not provided for or mentioned in the will. Such an “after-born” or pretermitted child may be entitled to a share of the estate as if the parent had died partially intestate, depending on what the other children received under the will.
This rule does not apply to a child who was already alive when the will was signed and was deliberately omitted. The lesson for anyone who has more children, or adopts, after signing a will: update or re-execute the will so that the disinheritance, or any intentional treatment, clearly reflects your current family. A will signed before a child existed will not automatically disinherit that child.
Why people disinherit a child
New York does not require any reason at all. People disinherit a child for personal reasons: estrangement, a long breakdown in the relationship, a feeling that one child already received substantial lifetime financial help, or a desire to direct more to a child who is less financially secure or who provided caregiving. None of these reasons needs to be proven or even stated. The law is concerned not with why you disinherit, but with whether the will was validly executed by a person with capacity and free of undue influence.
Outright disinheritance vs. a trust: which fits your situation?
Cutting a child out completely is not always the goal that best serves the family. In several common New York situations a trust is a better tool than an outright disinheritance.
| Situation | Better tool |
|---|---|
| A child with a disability | If the concern is protecting a child who receives, or may need, Medicaid or SSI, disinheriting them can be the wrong move. A properly drafted supplemental (special) needs trust lets you leave assets to benefit the child without disqualifying them from means-tested public benefits. |
| A child with addiction or spending problems | Rather than cutting the child off, a discretionary or spendthrift trust appoints a trustee to manage the funds, releasing money for the child’s benefit while preventing it from being dissipated. |
| A child you simply do not want to hand a lump sum | A trust can stagger distributions by age or condition instead of paying everything out at once. |
Choosing between outright disinheritance and a trust turns on your specific family and assets, and it is worth discussing with an attorney before signing anything.
No-contest (in terrorem) clauses in New York, and their limits
A no-contest clause, also called an in terrorem clause, says that a beneficiary who challenges the will forfeits whatever they were left. New York enforces these clauses under EPTL §3-3.5, but with significant limits, and they only work if the will actually leaves the child something to lose. If you disinherit a child completely, an in terrorem clause has no teeth against that child, because a person left nothing has nothing to forfeit.
A common contest-deterrent strategy is therefore to leave the child a modest but meaningful bequest paired with a no-contest clause, so the child must weigh the guaranteed gift against the risk and cost of litigating. Even then, EPTL §3-3.5 and the case law protect certain activities that will not trigger forfeiture, for example examining the witnesses and drafter under SCPA 1404 and preliminary pre-objection discovery (see also whether beneficiaries are entitled to a copy of the will). Whether an in terrorem clause makes sense for you depends on the dollar amounts and the family dynamics.
How a disinherited child can challenge the will
A disinherited child has standing to contest the will. The grounds and procedure for a New York will contest are covered in depth on our pages on how to win a will contest in New York and will-contest representation.
In the disinheritance context, the two grounds that matter most are lack of testamentary capacity and undue influence, usually pleaded together. A disinherited child often argues that whoever benefited from the disinheritance, whether a sibling, a new spouse or a caregiver, manipulated an elderly or ailing parent into changing the will. Because direct proof of undue influence is rare, courts allow it to be shown by circumstantial evidence: the testator’s health and dependency, the confidential relationship with the alleged influencer, that person’s opportunity and motive, and unexplained departures from prior estate plans. To attack capacity, the challenger must show the testator did not understand the nature of the act, the property they owned, or the natural objects of their bounty (their family).
How to make a New York disinheritance hold up in Surrogate’s Court
The goal is not just to disinherit. It is to disinherit durably, so the will survives a challenge. Each of the following steps strengthens a New York will.
| Step | Why it helps |
|---|---|
| Have the will drafted and its execution supervised by an estate attorney | A will executed under attorney supervision carries a presumption of due execution, which is meaningful weight in a contest. The drafting attorney is also typically the most important witness to the testator’s capacity and voluntariness. |
| Document capacity contemporaneously | Meeting the client in person, ideally more than once, and recording observations of the client’s understanding helps rebut a later capacity attack. In appropriate cases a treating physician’s contemporaneous letter can corroborate competency. |
| Keep the favored beneficiaries out of the process | If a sibling or new spouse will benefit, minimizing their involvement in the drafting and execution helps defeat a later undue-influence claim. |
| Include a self-proving affidavit | Executing the will with witness affidavits under SCPA 1406 simplifies probate. |
| State the disinheritance expressly | An express statement forecloses the argument that the child was omitted by oversight. |
| Consider, but do not overuse, a video of the execution | Video can help or hurt depending on how the testator presents; this is a case-by-case judgment call for counsel. |
| Update after life changes | Re-examine the will after a birth, adoption, marriage, divorce or major change in assets to avoid the pretermitted-child rule and the spousal election. |
Frequently asked questions
-
Can I disinherit an adult child in New York?
Yes. New York has no forced share for adult children. A validly executed will may leave an adult child nothing, and the child has no automatic statutory right to the estate.
-
Can I disinherit my spouse the same way?
No. Under EPTL §5-1.1-A a surviving spouse can elect against the will and claim the greater of $50,000 or one-third of the net estate, unless they validly waived that right. Spousal disinheritance requires special planning.
-
Do I have to mention the child in the will?
You do not have to, and omission alone is not grounds to overturn the will. However, expressly stating that you intentionally leave the child nothing is usually the stronger approach.
-
What if I have another child after I sign my will?
A child born or adopted after the will is executed who is not mentioned or provided for may claim a share under EPTL §5-3.2. Update your will after any new birth or adoption.
-
Will a no-contest clause stop a disinherited child from suing?
Only if the child is left something to forfeit. EPTL §3-3.5 enforces no-contest clauses but with limits, and a child left nothing has nothing to lose. Leaving a modest bequest with a no-contest clause is a common deterrent strategy.
-
Should I disinherit a disabled child outright?
Usually not. A supplemental needs trust can provide for the child without jeopardizing Medicaid or SSI, which outright disinheritance does not accomplish well.
