What Documents Belong in a Complete New York Estate Plan?

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. The will directs who inherits your property, a trust can help you avoid probate or protect assets, the power of attorney lets someone manage your finances if you cannot, and the health care proxy names someone to make medical decisions on your behalf. If you are putting together your first estate plan, that is the short answer — and the good news is that these are well-defined documents under New York law, not mysteries. Below, we walk through each one in plain English so you know exactly what belongs in your plan and why.

The Four Documents Every New Yorker Should Have

Think of these four documents as a team. Each handles a different job, and a gap in one can undermine the others. Here is the quick overview before we dig into the details.

Document	What it does	NY law
Last Will & Testament	Directs who inherits, names a guardian for minor children, appoints an executor	EPTL §3-2.1
Trust (revocable or irrevocable)	Avoids probate, protects assets, supports tax or Medicaid planning	EPTL Article 7
Durable Power of Attorney	Lets a trusted agent handle your finances if you are incapacitated	GOL §5-1513
Health Care Proxy	Names an agent to make medical decisions for you	Public Health Law Article 29-C

For a broader walkthrough of how these pieces fit together, see our estate planning overview.

1. Your Last Will and Testament

Your will is the foundation. It states who receives your property, names an executor to carry out your wishes, and — critically for young families — lets you nominate a guardian for minor children.

Under EPTL §3-2.1, a valid New York will must be:

• In writing and signed by you (the testator) at the end of the document;
• Witnessed by two attesting witnesses; and
• Accompanied by publication, meaning you declare to the witnesses that the document is your will.

These formalities matter. A will that ignores them can be challenged or thrown out, leaving your estate to pass under New York’s intestacy rules in EPTL Article 4 — the default law that decides who inherits when someone dies without a valid will. Intestacy rarely matches what people actually want, which is exactly why a properly executed will is step one. Learn more on our wills page.

2. Trusts: Avoiding Probate and Protecting Assets

Trusts, governed by EPTL Article 7, are where estate planning gets powerful. A trust is a legal arrangement that holds assets for your beneficiaries, and there are two broad types:

• Revocable living trust — You keep full control during your lifetime and can change or cancel it anytime. Its main benefit is avoiding probate, the court process of validating a will, so your assets pass privately and more quickly. Note: a revocable trust offers no estate-tax savings.
• Irrevocable trust — Once created, it generally cannot be changed, and that permanence is the point. Irrevocable trusts are used for tax reduction, asset protection, and Medicaid planning. New York’s Medicaid program imposes a five-year look-back on transfers, so this kind of planning works best when started early.

A special category, the supplemental needs trust (SNT) under EPTL 7-1.12, lets a person with disabilities receive an inheritance without losing eligibility for government benefits. If any part of this applies to your family, our trusts page goes deeper.

3. Durable Power of Attorney

The will and trust handle what happens to your property — but what if you are alive and simply unable to manage your own affairs after an accident or illness? That is the job of the durable power of attorney, governed by GOL §5-1513.

This document names an agent to handle your finances: paying bills, managing accounts, dealing with real estate, and more. In New York, a power of attorney is durable by default, meaning it stays in effect even if you become incapacitated — which is precisely when you need it most. New York uses a 2021 statutory short form, and getting the execution right is essential because banks and institutions scrutinize these documents closely. See our power of attorney page for details.

4. Health Care Proxy

The financial side is covered, but medical decisions are different and require their own document. The health care proxy, authorized by New York Public Health Law Article 29-C, appoints an agent to make medical decisions for you if you cannot communicate them yourself.

This is distinct from the financial power of attorney — your money agent and your medical agent are separate roles, and they can be different people. Together, the durable power of attorney and the health care proxy cover both halves of incapacity planning: your finances and your health.

A Word on New York Estate Tax

Most first-time planners do not have a taxable estate, but it helps to know the landscape. For deaths on or after January 1, 2026 through December 31, 2026, New York provides a basic exclusion amount of $7,350,000. New York also has a feature unique among the states — the “cliff.”

If your taxable estate exceeds 105% of the exclusion ($7,717,500), you lose the entire exemption 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 the taxable estate. If your estate is approaching these numbers, planning with trusts becomes especially important. Our NY estate tax guide explains the cliff in more detail.

How the Documents Work Together

The strength of an estate plan is in the coordination. A will without a power of attorney leaves a gap during incapacity. A trust that is never funded does not avoid probate. A health care proxy without a financial power of attorney covers only half of an emergency. A complete plan ensures these documents reference and reinforce one another — which is why building them together, with one attorney, beats assembling them piecemeal. Because this guidance applies across the state, our NY statewide guide covers how these rules reach every county.

Frequently Asked Questions

Do I really need a trust if I already have a will?
Not everyone does. A will alone is sufficient for many first-time planners. A trust becomes valuable if you want to avoid probate, protect assets, plan for Medicaid, or provide for a beneficiary with special needs.

What happens if I die without a will in New York?
Your estate passes under New York’s intestacy law (EPTL Article 4), which uses a fixed formula to decide who inherits. That formula rarely matches personal wishes, especially for unmarried partners or blended families.

Is a power of attorney the same as a health care proxy?
No. A durable power of attorney (GOL §5-1513) covers financial decisions, while a health care proxy (Public Health Law Article 29-C) covers medical decisions. You need both for complete incapacity planning.

Will a revocable living trust reduce my estate taxes?
No. A revocable living trust helps you avoid probate but provides no estate-tax savings. Tax reduction is the role of an irrevocable trust.
