A will is only as strong as the day you sign it. In New York, the most heartbreaking estate disputes rarely involve people who never planned — they involve people who did plan, but whose wills were executed incorrectly. A missing witness, a signature in the wrong place, or a misunderstanding about what document you actually signed can unravel years of careful thought in a single afternoon at the Surrogate’s Court.
At Morgan Legal Group, attorney Russel Morgan, Esq. and our team focus on the part of estate planning most people overlook: getting the execution right under EPTL §3-2.1. This page walks through the most common and most expensive mistakes New Yorkers make when signing a will — across New York City, Long Island, Westchester, the Hudson Valley, and Upstate — and how to avoid each one.
Why Execution Errors Are So Costly
Many people assume a will is valid as long as it reflects their wishes. It isn’t. New York law treats will execution as a strict, formal act. If the statutory formalities under EPTL §3-2.1 aren’t met, the document can be denied probate — meaning it has no legal effect at all.
When a will fails, the law doesn’t guess at your intentions. Instead, your property passes under New York’s intestacy rules in EPTL Article 4, distributing your estate to your next of kin by a fixed statutory formula — which may be the exact opposite of what you wanted. See our overview of what happens with no valid will.
The Most Common (and Costly) NY Will Execution Mistakes
The table below summarizes the pitfalls we see most often, the rule behind each, and the consequence of getting it wrong.
| Mistake | The NY Rule (EPTL §3-2.1) | Why It’s Costly |
|---|---|---|
| Using only one witness | At least two attesting witnesses are required | A one-witness will fails the core formality and can be denied probate |
| Witnesses signing weeks apart | Both witnesses must sign within one 30-day period | Falling outside the window invites a challenge to validity |
| Signing in the middle or margin | The testator must sign at the end of the will | Provisions written after the signature may be disregarded |
| Never declaring it’s your will | The testator must declare (publish) the instrument as their will | Without publication, witnesses can’t properly attest |
| Witnesses don’t see signing or acknowledgment | Sign in witnesses’ presence, or acknowledge your signature to each | Improper acknowledgment is a frequent ground for contest |
| Omitting witness addresses | Witnesses sign at the testator’s request and add their residence addresses | Missing details weaken the proof and slow probate |
Mistake 1: Treating Two Witnesses as Optional
New York requires at least two attesting witnesses. A will signed before a single witness — or one signed at a kitchen table with only a notary — does not satisfy EPTL §3-2.1. Worse, choosing witnesses who are also beneficiaries can create disputes. Learn the full checklist on our NY will requirements page.
Mistake 2: Letting the Witnesses Sign Too Far Apart
Both attesting witnesses must sign within one 30-day period. New York applies a rebuttable presumption that this 30-day requirement is met — but that presumption can be challenged. If your witnesses sign weeks or months apart, you hand a will contestant an opening. A properly supervised will execution ceremony eliminates this risk by having everyone sign together.
Mistake 3: Signing in the Wrong Place
The testator must sign at the end of the will. This is not a formality you can fudge. Language that appears after your signature may be treated as if it were never there. If you cannot physically sign, New York permits another person to sign in your presence and at your direction — but that, too, must be done correctly.
Mistake 4: Skipping the Declaration (Publication)
You must declare the instrument to be your will — this is called publication. Witnesses need to understand they are witnessing a will, not some other paper. Silently sliding a document across a table and asking someone to sign undermines their ability to attest, which is exactly what a will contest targets.
Mistake 5: Confusing a Living Will With Your Property Will
This is one of the most damaging misunderstandings we encounter. A living will is a separate health-care document that states your wishes about end-of-life medical treatment. It does not distribute your property. A property will (governed by EPTL §3-2.1) takes effect only at death and must be admitted to probate in the Surrogate’s Court. Believing your living will “covers everything” can leave your estate with no valid property will at all.
Mistake 6: Forgetting Your Spouse’s Right of Election
Even a perfectly executed will can be partially overridden. Under the spousal right of election (EPTL 5-1.1-A), a surviving spouse can claim a minimum statutory share of your estate regardless of what your will says. Planning around — not against — this right is essential to avoid surprise litigation.
Mistake 7: Amending a Will the Wrong Way
Crossing out a clause, writing in the margin, or stapling a note to your will does not legally amend it. Changes must be made through a properly executed codicil or a new will, following the same EPTL §3-2.1 formalities. See codicils and amendments before you touch an existing will.
Getting It Right From the Start
Most of these mistakes share a single root cause: a will drafted or signed without proper supervision. A supervised execution ensures the right number of witnesses, correct signature placement, clear publication, and complete attestation — all in one sitting.

Frequently Asked Questions
Q: How many witnesses does a will need in New York?
A: At least two attesting witnesses are required under EPTL §3-2.1. Both must sign within one 30-day period, and they should add their residence addresses when they sign at your request.
Q: Where exactly do I sign my New York will?
A: You must sign at the end of the will. If you are unable to sign, another person may sign for you in your presence and at your direction.
Q: Is a living will the same as a regular will?
A: No. A living will addresses health-care and end-of-life decisions. A property will (EPTL §3-2.1) directs how your assets pass at death and must be admitted to probate in the Surrogate’s Court. They are entirely separate documents.
Q: What happens if my will is found invalid?
A: If a will fails the execution requirements, the estate is distributed under New York’s intestacy rules in EPTL Article 4, passing to your next of kin by statutory formula rather than your stated wishes.
Q: Can my spouse override my will?
A: To a degree, yes. The spousal right of election under EPTL 5-1.1-A allows a surviving spouse to claim a minimum share of the estate regardless of the will’s terms.
