A complete New York estate plan is built on four core documents that work together: a last will and testament, one or more trusts, a durable power of attorney, and a health care proxy. If you have all four — coordinated so they don’t contradict one another — you have covered the essentials that decide who inherits your property, who manages your money if you cannot, and who makes your medical decisions. Everything else is refinement. If that sounds like a lot, take a breath: this guide walks first-timers through each piece in plain language, so you can see exactly what each document does and why it belongs in the plan.
Many people assume a will alone is “an estate plan.” It is an important start, but a will only speaks after you die, and only about your probate assets. A real plan also protects you while you are alive — when an accident, illness, or aging means someone has to step in for you. That is the gap the other three documents fill. For a broader picture of how these fit together, see our estate planning overview.
The Four Essential Documents at a Glance
| Document | What it does | When it works | Governing NY law |
|---|---|---|---|
| Last Will & Testament | Names who inherits, names guardians for minor children, names your executor | After death (through probate) | EPTL §3-2.1 |
| Trust (revocable or irrevocable) | Holds and passes assets outside probate; can protect assets and benefits | During life and after death | EPTL Article 7 |
| Durable Power of Attorney | Lets a trusted agent handle your finances if you can’t | During life, if you’re incapacitated | GOL §5-1513 |
| Health Care Proxy | Lets a trusted agent make medical decisions for you | During life, if you can’t decide | Public Health Law Article 29-C |
1. The Last Will and Testament
Your will is the document most people picture first. It states who receives your property, names a guardian for any minor children, and names the executor who will carry out your wishes. To be valid in New York, a will must meet the formal requirements of EPTL §3-2.1: you (the testator) must sign at the end of the document, you must sign or acknowledge it in front of two attesting witnesses, and you must “publish” the will — meaning you declare to the witnesses that the document is your will.
What happens if you skip this step? If you die without a valid will, you die intestate, and New York’s intestacy rules under EPTL Article 4 decide who inherits — not you. Those default rules may send assets to relatives you would not have chosen, and they offer no chance to name a guardian for your children. That is why even a simple will is foundational.

2. Trusts
A trust is a legal arrangement, governed by EPTL Article 7, in which a trustee holds property for your beneficiaries. Trusts are flexible, and the right type depends on your goals:
- Revocable living trust. You keep full control and can change it any time. Its main benefit is avoiding probate — assets in the trust pass privately to your beneficiaries without court involvement. Important to know: a revocable trust does not save estate taxes.
- Irrevocable trust. Once created, it generally cannot be changed, and in exchange it offers benefits a revocable trust cannot: estate-tax reduction, asset protection, and Medicaid planning (subject to the five-year look-back). This is a common tool for protecting a home or savings from long-term-care costs.
- Supplemental needs trust (SNT). Authorized under EPTL §7-1.12, an SNT lets you provide for a loved one with a disability without disqualifying them from means-tested government benefits.
Not everyone needs a trust, and that is fine — this is where personalized advice matters. Our trusts page explains the options in more depth.
3. The Durable Power of Attorney
This is the document that protects your finances while you are alive. A power of attorney under GOL §5-1513 lets you appoint an agent to handle financial and legal matters — paying bills, managing accounts, dealing with property — if you become unable to do so yourself. In New York, a properly executed power of attorney is durable by default, meaning it stays in effect even if you later lose capacity.
New York overhauled this document with the 2021 statutory short form, which simplified the format and made it easier for banks to accept. Without a valid power of attorney, your family may have to go to court for a guardianship to manage your affairs — slower, costlier, and more stressful than signing the document now. See our power of attorney page for the details.
4. The Health Care Proxy
The fourth essential is the one people most often overlook. A health care proxy, authorized by New York Public Health Law Article 29-C, lets you name an agent to make medical decisions for you if you cannot speak for yourself. This is entirely separate from the financial power of attorney — money decisions and medical decisions go to different documents, and you can name different people for each.
A health care proxy ensures that someone you trust — not a court or a distant relative — is empowered to talk with your doctors and honor your wishes during a health crisis. Many New Yorkers pair it with a living will expressing their treatment preferences.
A Word on New York Estate Taxes
For most first-time planners, estate tax is not an immediate worry — but it helps to know where the line is. For deaths in 2026 (on or after January 1, 2026 through December 31, 2026), New York’s basic exclusion amount is $7,350,000. Estates below that owe no New York estate tax.
New York has an unusual feature called the “cliff.” If your taxable estate exceeds 105% of the exclusion — $7,717,500 in 2026 — you lose the exemption entirely and the estate is taxed from the first dollar, at progressive rates of 3% to 16%. New York has no gift tax, but gifts made within three years of death are added back into your taxable estate. If your assets are anywhere near these figures, trust planning becomes important. Our NY estate tax guide covers this in detail.
Frequently Asked Questions
Do I really need all four documents?
For a truly complete plan, yes. A will handles what happens after death; the power of attorney and health care proxy protect you while you’re alive; and trusts add probate avoidance, tax planning, or asset protection where needed. Each covers a gap the others don’t.
Is a will enough on its own?
A will is essential but incomplete. It does nothing if you become incapacitated, and it doesn’t avoid probate. Without a power of attorney and health care proxy, your family could face a court guardianship to act for you.
What’s the difference between a power of attorney and a health care proxy?
The power of attorney (GOL §5-1513) covers financial and legal decisions; the health care proxy (Public Health Law Article 29-C) covers medical decisions. They are separate documents, and you can appoint different agents for each.
Does a living trust reduce my estate taxes?
No. A revocable living trust avoids probate but offers no estate-tax savings. Tax reduction comes from irrevocable trusts and other strategies — which is why coordinating your documents matters.
