Yes, in New York you can disinherit most people in your will, including adult children, siblings, parents, and more distant relatives, simply by leaving them out or naming them as expressly excluded. New York imposes no obligation to provide for an adult child or any blood relative. There is one major exception: you generally cannot fully disinherit a surviving spouse. Under the spousal right of election (EPTL 5-1.1-A), a surviving husband or wife can claim a minimum share of your estate no matter what your will says. Understanding where the line falls, and building a plan that respects it, is the difference between a wish that holds up in the Surrogate’s Court and one that unravels.
This is exactly the kind of decision where consultative planning earns its keep. Disinheritance is rarely a single line in a document. It is a strategy involving the right instrument, the right language, and, critically, the right fiduciaries to carry it out. Below we walk through what New York law actually permits, where it pushes back, and how to think like an advisor about your choices.
What New York Lets You Disinherit
A New York will is your declaration of who receives your property at death. It takes effect only when you die and must be admitted to probate in the Surrogate’s Court. Within that document, your authority to direct your estate is broad. You can leave a relative one dollar, name them as deliberately excluded, or simply not mention them at all.
People you can typically disinherit:
- Adult children — New York gives no automatic inheritance right to grown children.
- Estranged relatives — siblings, parents, cousins, nieces, and nephews have no claim against a valid will.
- Former partners — anyone you are not legally married to has no protected share.
- Charities or prior beneficiaries — you are free to redirect property you previously intended for someone else.
The key word throughout is valid. A disinheritance only works if the will itself is properly executed under New York law. A defective will can be denied probate, and if that happens, your estate may pass under intestacy (EPTL Article 4) to the very next of kin you tried to exclude. That is why the mechanics of execution matter as much as the wishes themselves. See our NY will requirements overview for the full execution checklist.
The One You Cannot Disinherit: The Surviving Spouse
The most important limit on disinheritance 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 law’s minimum, may elect to take a statutory share against the estate instead of accepting what the will provides.
This right exists to protect a spouse from being cut out, and it applies even if your will clearly and intentionally leaves your spouse nothing. The election is a personal right the surviving spouse must affirmatively exercise; it is not automatic, but it is available to them by statute regardless of your contrary instructions.
A few practical points to understand:
- The right belongs to a legal surviving spouse. Unmarried partners do not have it.
- Certain assets and transfers are counted toward the calculation, so simply moving property out of the will does not always defeat the share.
- Because the election can override your stated plan, attempting to disinherit a spouse without professional guidance is one of the riskiest things a testator can do.
If protecting or limiting a spouse’s share is your goal, the consultative path is a structured one: prenuptial or postnuptial agreements, lifetime planning, and trusts are tools an estate attorney evaluates together, not a single clause inserted at signing.
Disinheritance Is a Strategy, Not a Sentence
The advisory question is never just “can I cut someone out?” It is “what plan accomplishes my goal and survives a challenge?” Disinherited individuals are the people most likely to contest a will, so the document must be built to withstand scrutiny.
A sound disinheritance plan typically considers:
| Element | Why It Matters |
|---|---|
| Clear language | Naming the excluded person removes ambiguity that a contest could exploit. |
| Proper execution | A will that fails EPTL §3-2.1 formalities can be denied probate entirely. |
| No-contest provisions | Carefully drafted clauses can discourage litigation by beneficiaries. |
| Capacity and undue influence | Records and process help defend against the most common grounds for challenge. |
| The right fiduciaries | An executor who is impartial and capable keeps the plan from stalling in administration. |
This is where choosing the right people becomes part of the legal strategy. The executor you name will be the one defending your choices in front of the Surrogate’s Court. Naming a person who is conflicted, unwilling, or already in tension with the disinherited party can sink an otherwise solid plan. Our guidance on will drafting walks through how instrument and fiduciary choices fit together.
Getting the Execution Right
New York does not enforce intentions; it enforces validly executed documents. To disinherit someone successfully, the underlying will must satisfy EPTL §3-2.1:
- The testator must sign at the end of the will (or direct another to sign in their presence).
- The testator must declare the instrument to be their will (publication) to the witnesses.
- There must be at least two attesting witnesses.
- The testator either signs in the witnesses’ presence or acknowledges the signature to each witness.
- The witnesses sign at the testator’s request and add their residence addresses.
- Both witnesses must sign within one 30-day period, with a rebuttable presumption that this requirement is satisfied.
Skip any of these and the disinheritance you intended may collapse, sending your estate into intestacy under EPTL Article 4 — often to the exact relatives you meant to exclude. For the step-by-step ceremony, see our will execution guide.
One common confusion to clear up: a living will is a health-care and end-of-life directive, not a property document. It has no role in who inherits your estate.

Frequently Asked Questions
Can I disinherit my adult children in New York?
Yes. New York does not require you to leave anything to adult children. A clearly worded, validly executed will can exclude them entirely.
Can I disinherit my spouse in New York?
Generally no. Under the spousal right of election (EPTL 5-1.1-A), a surviving spouse can claim a statutory minimum share of your estate even if your will leaves them out. Spousal planning usually requires additional tools like a marital agreement.
What happens if my will is invalid?
If your will fails the EPTL §3-2.1 execution requirements, it can be denied probate. Your estate would then pass under intestacy (EPTL Article 4) to your next of kin — possibly the people you intended to disinherit.
Will disinheriting someone cause a will contest?
It can. Disinherited individuals are the most likely to challenge a will. Clear language, proper execution, and a capable, impartial executor are your best protections.
Plan It With an Advisor, Not a Template
Disinheritance is one of the most consequential, and most contested, choices in estate planning. The law gives you wide latitude over relatives but draws a firm line around your spouse, and the entire plan rises or falls on flawless execution and the right fiduciaries. This is a decision to make with counsel who can pressure-test it.
