How to Make a Will in New York — EPTL 3-2.1 & Manhattan Probate

A will is a written, signed legal document that directs how your property is distributed after death and names the executor who will carry out your wishes. In New York, a valid will must meet the execution formalities of EPTL 3-2.1 — signed at the end by the testator and witnessed by two people. After death, a Manhattan resident’s will is offered for probate at the New York County Surrogate’s Court, 31 Chambers Street.

A will is the foundation of most Manhattan estate plans, but it is frequently misunderstood. It does not avoid probate — it directs probate. And for a New York County resident whose largest asset is a co-op or condo, the will is only one part of the picture, because much of what you own may pass outside it entirely.

Will (defined): A revocable instrument, effective only at death, in which a person (the testator) names beneficiaries, appoints an executor, and may create testamentary trusts. It controls only assets titled in the decedent’s sole name without a beneficiary designation.

What are New York’s requirements for a valid will?

Under EPTL 3-2.1, a will is properly executed in New York only if:

1. It is in writing and signed at the end by the testator (or by another person at the testator’s direction and in the testator’s presence).
2. The signature is made or acknowledged in the presence of at least two attesting witnesses.
3. The testator declares the document to be a will to the witnesses.
4. The witnesses sign within 30 days of one another and write their addresses.

These formalities are strict. A will that fails EPTL 3-2.1 — for example, signed without two witnesses — can be denied probate, throwing the estate into intestacy. Because Manhattan estates are high-value, defects here invite costly will contests, so precise execution is essential.

What does a will not control?

A common Manhattan mistake is assuming the will governs everything. It does not control:

• Jointly owned property with rights of survivorship (passes automatically to the survivor).
• Beneficiary-designation assets — IRAs, 401(k)s, life insurance, and payable-on-death accounts pass to the named beneficiary.
• Assets held in a trust — these pass under the trust terms, not the will. See our trusts guide.

For many New York County residents, retirement and insurance assets dwarf the probate estate, so coordinating designations with the will is critical.

What happens if you die without a will in New York?

Dying without a valid will means dying intestate, and New York’s intestacy statute, EPTL 4-1.1, dictates who inherits — regardless of your wishes.

Survived by	Who inherits (EPTL 4-1.1)
Spouse, no children	Entire estate to spouse
Spouse and children	First $50,000 + half of the balance to spouse; remainder to children
Children, no spouse	Entire estate to children, equally (by representation)
Parents, no spouse/children	Entire estate to parents
No spouse, children, or parents	To siblings, then more remote kin

For a Manhattan co-op owner with a partner but no marriage, intestacy can be devastating — an unmarried partner inherits nothing under EPTL 4-1.1.

Are handwritten or oral wills valid in New York?

Rarely. Under EPTL 3-2.2, New York recognizes holographic (entirely handwritten, unwitnessed) and nuncupative (oral) wills only for limited classes — members of the armed forces during armed conflict and mariners at sea — and even then they expire after a set period. For practical purposes, a Manhattan resident needs a formally executed EPTL 3-2.1 will.

What is a self-proving affidavit?

A self-proving affidavit is a sworn statement, signed by the witnesses before a notary at the time of execution, attesting that the formalities were met. It lets the New York County Surrogate’s Court admit the will to probate without locating the witnesses years later — a major time-saver in a busy court like Manhattan’s.

How do you update or revoke a will in New York?

You can amend a will with a codicil (executed with the same EPTL 3-2.1 formalities) or revoke it under EPTL 3-4.1 — by a later will, or by physical act (burning, tearing, or destroying it with intent to revoke). Marriage, divorce, and new children can also alter how a will operates, so Manhattan residents should review their wills after any major life change.

How your will is probated in Manhattan

When you die domiciled in New York County, your executor files the original will with the New York County Surrogate’s Court at 31 Chambers Street and petitions for letters testamentary.

Frequently asked questions

Do I need a lawyer to make a will in New York? Not legally, but DIY wills frequently fail EPTL 3-2.1 formalities and are the leading cause of denied probate. For a Manhattan co-op or high-value estate, a drafting error can cost far more than the will.

Can I disinherit my spouse in a New York will? Not entirely. Under EPTL 5-1.1-A, a surviving spouse has a right of election to claim roughly one-third of the estate, even against the will’s terms.

Where is my will kept? Keep the original somewhere your executor can find it; the Surrogate’s Court requires the original, not a copy, to admit it to probate.
