Yes — in New York you can disinherit most people in your will, including adult children, parents, siblings, and other relatives, with one major exception: you generally cannot fully disinherit a surviving spouse. Under New York’s Estates, Powers and Trusts Law (EPTL) §5-1.1-A, a surviving spouse has a “right of election” to claim a minimum share of your estate no matter what your will says. Everyone else can be left out, but only if your will is drafted and executed so precisely that no one can successfully challenge it. This is where a true all-in-one plan matters: disinheritance is not just about what you leave out — it is about closing every door a disappointed heir might use to get back in.
At Total Will Law, powered by Morgan Legal Group and led by Russel Morgan, Esq., we treat disinheritance as one piece of a complete, single-plan strategy that covers your will, your witnesses, your beneficiary designations, and the contingencies most people forget. Below, we break down exactly what New York law allows, where it draws hard lines, and how to do it the right way.
The General Rule: New York Honors Your Right to Choose
New York is, at its core, a state that respects testamentary freedom. With the spousal exception noted above, you are free to decide who receives your property. That means:
- Adult children have no automatic right to inherit. You may leave a child more, less, or nothing at all.
- Parents, siblings, nieces, nephews, and friends have no guaranteed share.
- A person you simply dislike can be intentionally excluded.
The critical word is intentionally. A person you forget to mention is treated very differently from a person you deliberately and clearly exclude. To make your wishes stick, the disinheritance must be unmistakable on the face of a valid will. A vague or sloppy document invites a will contest — and a contest is precisely the outcome an all-in-one plan is built to prevent.
For the foundation of any disinheritance strategy, start with a properly drafted instrument. See our will drafting overview to understand how the document is structured from the ground up.
The One Person You Usually Cannot Disinherit: Your Spouse
The single largest exception in New York is the spousal right of election under EPTL §5-1.1-A. A surviving spouse who is left out of the will — or left less than the statutory minimum — may “elect against” the will and claim a guaranteed share of the estate. The right of election is a deliberate policy choice by New York: a marriage carries financial obligations that a will alone cannot erase.
A few key points about the elective share:
- It is a personal right of the surviving spouse; it must be affirmatively claimed within the statutory timeframe.
- It generally reaches not just the probate estate but certain other “testamentary substitutes,” so simply moving assets out of the will does not automatically defeat it.
- It can be waived — but only through a valid written waiver, such as a properly executed prenuptial or postnuptial agreement signed before death.
In short, you cannot quietly write your spouse out of your will and expect it to hold. If your goal involves limiting a spouse’s inheritance, that result must be achieved through lawful tools — chiefly a signed waiver — not through silence in the will.
Important: A “living will” is not a property will. A living will is a health-care and end-of-life document that states your medical wishes. It does not control who inherits your money or property and plays no role in disinheritance. New York will-based disinheritance flows entirely through your last will and testament and the EPTL.
Who You Can and Cannot Disinherit in New York
| Person | Can you disinherit them? | Why |
|---|---|---|
| Surviving spouse | Generally no | Protected by the elective share, EPTL §5-1.1-A |
| Adult child | Yes | No automatic right to inherit |
| Minor child | Yes, but plan carefully | No forced share, though support obligations and guardianship issues may apply |
| Parents | Yes | No guaranteed share |
| Siblings / extended family | Yes | No guaranteed share |
| Unmarried partner | They inherit only if named | No intestate rights without a marriage or a will gift |
What Happens If You Have No Will at All
Disinheritance only works through a valid will. If you die without a will (intestate), you lose all control over who inherits. Distribution is dictated entirely by statute — EPTL Article 4 — which sends your property to your closest next of kin in a fixed order. The very people you wanted to exclude may inherit by default simply because the law, not you, is deciding.
This is the trap an all-in-one plan avoids: relying on intestacy is the opposite of disinheriting someone. To understand the default rules and why they rarely match anyone’s true wishes, read our guide to intestacy when there is no will.
How to Disinherit Someone the Right Way
Successfully excluding an heir depends on two things: a clearly worded will and a flawlessly executed will. New York’s execution rules under EPTL §3-2.1 are strict, and a will that fails them can be thrown out entirely — handing your estate to intestacy and the very heirs you tried to exclude.
To be validly executed in New York, your will must meet each of these requirements:
- The testator signs at the end of the will. Your signature must appear at the end of the document. Alternatively, another person may sign for you, but only in your presence and at your direction.
- At least two attesting witnesses. New York requires a minimum of two witnesses.
- Publication. You must declare to the witnesses that the instrument is your will.
- Signature or acknowledgment in the witnesses’ presence. You either sign in the presence of the witnesses or acknowledge your earlier signature to each of them.
- Witnesses sign at your request and add their addresses. The witnesses sign at your request and write their residence addresses on the will.
- The 30-day window. Both witnesses must sign within one 30-day period. The law applies a rebuttable presumption that this requirement was satisfied.
For a deeper walkthrough of these formalities, see our pages on New York will requirements and will execution. When disinheritance is on the line, perfect execution is not optional — it is the difference between your wishes being honored and a court ignoring them.
Smart Drafting Practices for a Disinheritance
Beyond bare execution, experienced drafting strengthens an intentional exclusion:
- Name the person and state the intent clearly. A will that affirmatively states an heir is being excluded leaves far less room for a “they were forgotten” argument.
- Avoid leaving the matter to silence. Silence creates ambiguity; ambiguity invites litigation.
- Consider a no-contest (in terrorem) clause. Giving a token gift paired with a clause discouraging challenges can make contesting risky for the excluded party — a strategy that must be drafted with care.
- Keep the plan current. Life changes — divorce, new children, deaths — can quietly undo your intent. When circumstances shift, update the plan through a properly executed codicil or amendment rather than handwritten notes.
Remember that a will takes effect only at death and must be admitted to probate in the Surrogate’s Court. Until then, it is a private document you can revise. The all-in-one approach keeps every layer — will, waivers, beneficiary designations, and contingencies — aligned so there are no gaps for a determined heir to exploit.
Frequently Asked Questions
Can I disinherit my adult child in New York?
Yes. Adult children have no automatic right to inherit under New York law. As long as your will is validly executed under EPTL §3-2.1 and your intent to exclude the child is clear, the disinheritance is enforceable.
Can I completely disinherit my spouse?
Generally no. Under EPTL §5-1.1-A, a surviving spouse can elect to take a minimum statutory share regardless of the will. The most reliable way to limit a spouse’s inheritance is a valid signed waiver, such as a prenuptial or postnuptial agreement.
What if I just leave the person out without mentioning them?
That is risky. Silence can be read as an oversight rather than intent, which opens the door to a will contest. A clear, express statement of exclusion in a properly executed will is far stronger.
Does a living will affect who inherits my property?
No. A living will is a health-care document covering medical and end-of-life decisions. It has no effect on the distribution of your property — that is governed by your last will and testament and the EPTL.
Build a Complete Plan — Not Just a Will With a Gap
Disinheriting someone in New York is entirely possible, but only when every base is covered in a single, coordinated plan: a clearly worded exclusion, flawless EPTL §3-2.1 execution, the right handling of the spousal elective share, and updates as life changes. Miss one piece and your wishes can unravel.
