A complete New York estate plan rests on four coordinated documents: a last will and testament, one or more trusts, a durable power of attorney, and a health care proxy. Together they answer the questions every family eventually faces — who receives your property, who manages your finances if you cannot, and who makes your medical decisions in an emergency. If you are building your first plan, take a breath: you do not need to understand every legal nuance today. You need to understand what each document does and why they work best as a team. This guide walks through the essentials in plain language, with the actual New York laws that govern each piece.
The Four Core Documents at a Glance
Think of these documents as covering two timelines: what happens while you are alive (but perhaps unable to act) and what happens after you pass away.
| Document | Governing NY Law | What It Does | When It Works |
|---|---|---|---|
| Last Will & Testament | EPTL §3-2.1 | Names who inherits your property and who serves as executor | After death (through probate) |
| Trust (revocable or irrevocable) | EPTL Article 7 | Holds and transfers assets, can avoid probate | During life and after death |
| Durable Power of Attorney | GOL §5-1513 | Lets a trusted agent handle your finances | While you are alive but incapacitated |
| Health Care Proxy | Public Health Law Art. 29-C | Lets an agent make medical decisions | While you are alive but unable to decide |
The mistake first-timers most often make is treating these as a menu to pick from. They are not. A will without a power of attorney leaves your finances frozen if you become incapacitated. A trust without a coordinated will can leave assets unaccounted for. The strength is in the coordination. Our estate planning overview explains how the pieces fit together as one plan.
1. The Last Will and Testament
Your will is the foundation document. It names the people who will inherit your property, appoints an executor to carry out your wishes, and — critically for parents — can nominate a guardian for minor children.
New York is strict about how a will must be signed. Under EPTL §3-2.1, a valid will requires:
- Two attesting witnesses who watch you sign (or acknowledge your signature)
- The testator’s signature at the END of the document
- Publication — you must declare to the witnesses that the document is your will
These formalities are not bureaucratic hoops; they are what makes the will enforceable. A homemade will that misses a step can be challenged or thrown out.
What happens if you die without a will? New York’s intestacy rules under EPTL Article 4 take over and distribute your property according to a fixed statutory formula — not your wishes. Your spouse, children, or more distant relatives inherit in shares the law dictates, and the court appoints an administrator you never chose. For most families, that is reason enough to put a will in place. Learn more on our wills page.
2. Trusts: Probate Avoidance and Beyond
A trust is a legal arrangement, governed by EPTL Article 7, that holds assets for the benefit of the people you name. Trusts are where estate planning gets flexible, and they come in two broad families.
A revocable living trust lets you keep full control during your lifetime — you can change or cancel it any time — and it allows the assets it holds to pass to your beneficiaries without going through probate. That can save your family time and the public court process. Important honesty point: a revocable trust does not save estate taxes. Its benefit is privacy and probate avoidance, not tax reduction.
An irrevocable trust gives up some control in exchange for powerful protections. It is the tool used for tax reduction, asset protection, and Medicaid planning. Because assets moved into the right irrevocable trust can be removed from your taxable estate and, after New York’s five-year look-back period, sheltered for Medicaid eligibility, it is a cornerstone of long-term-care planning.
A special category — the Supplemental Needs Trust (SNT) under EPTL 7-1.12 — lets you provide for a loved one with disabilities without disqualifying them from means-tested government benefits. See our trusts page for which type fits your situation.
3. The Durable Power of Attorney
A will and a trust both look forward to events that mostly matter after death or after careful planning. The durable power of attorney protects you right now. It lets you name an agent to manage your finances — pay bills, handle accounts, manage property — if you become incapacitated.
Under GOL §5-1513, a New York power of attorney is durable by default, meaning it remains valid even if you later lose mental capacity (which is precisely when you need it most). New York uses a 2021 statutory short form that modernized the document and made it easier for banks and institutions to accept.
Without a durable POA, if you become incapacitated your family may have to petition a court for guardianship — a slow, public, and expensive process that the POA is designed to avoid. Visit our power of attorney page to learn how this document works.
4. The Health Care Proxy
The fourth pillar is the health care proxy, governed by New York Public Health Law Article 29-C. It appoints an agent to make medical decisions on your behalf when you cannot speak for yourself.
This is a common point of confusion, so let’s make it clear: the health care proxy is separate from the financial power of attorney. The POA handles money; the proxy handles medicine. Your financial agent and your medical agent can be the same person, but they are two distinct legal documents serving two distinct purposes. A complete plan needs both.

What About New York Estate Tax?
For most first-time planners, estate tax will not be an immediate concern — but it is worth understanding because New York has a feature that surprises people.
For deaths on or after January 1, 2026 through December 31, 2026, New York’s basic exclusion amount is $7,350,000. Estates below that figure owe no New York estate tax.
The surprise is the “cliff.” New York phases out the exemption as an estate approaches 105% of the exclusion — $7,717,500. An estate that exceeds that cliff loses the entire exemption and is taxed from dollar one, at progressive rates of 3% to 16%. This is why high-net-worth families plan carefully around the threshold.
Two more useful facts: New York has no gift tax, but gifts made within three years of death are added back into the taxable estate. Our New York estate tax guide walks through the numbers in detail.
Frequently Asked Questions
Do I really need all four documents, or can I start with just a will?
A will is a fine starting point, but it only takes effect after death. If your goal is a complete plan, the durable power of attorney and health care proxy protect you during your lifetime — and those moments often arrive first. We recommend coordinating all four.
What is the difference between a power of attorney and a health care proxy?
The durable power of attorney (GOL §5-1513) covers your finances. The health care proxy (Public Health Law Art. 29-C) covers your medical decisions. They are separate documents and a complete plan includes both.
Does a revocable living trust lower my estate taxes?
No. A revocable trust helps you avoid probate and keep your affairs private, but it offers no estate-tax savings. Tax reduction comes from irrevocable trusts and other planning tools.
What happens if I die without a will in New York?
Your property is distributed under New York’s intestacy statute, EPTL Article 4, according to a fixed formula — not your personal wishes — and a court appoints an administrator. A valid will under EPTL §3-2.1 keeps those decisions in your hands.
