You should review your New York estate plan every three to five years, and immediately after any major life event — a marriage, divorce, birth, death, large change in assets, a move into or out of New York, or a shift in the tax law. A plan is not a one-time document you sign and file away; it is a coordinated set of instruments — your will, your trust(s), your durable power of attorney, and your health care proxy — that must keep pace with your life. When even one of those documents falls out of date, the others can be thrown off too, because in a complete estate plan every piece is designed to work together. This guide walks you through the entire plan, start to finish, and shows you exactly when each component needs a fresh look.
The Four Documents in a Complete New York Estate Plan
Before you can know when to update, you need to see what you are updating. A comprehensive New York plan is built from four coordinated pieces. Skip one, and you leave a gap that the others cannot fill.
| Document | Governing Law | What It Controls | Effective When |
|---|---|---|---|
| Last Will & Testament | EPTL §3-2.1 | Distribution of probate assets; guardians for minor children | At death (through probate) |
| Trust (revocable or irrevocable) | EPTL Article 7 | Assets you transfer into it; avoids probate | During life and after death |
| Durable Power of Attorney | GOL §5-1513 | Your financial and legal affairs | While you are alive but incapacitated |
| Health Care Proxy | Public Health Law Article 29-C | Your medical decisions | When you cannot speak for yourself |
These four are not interchangeable. Your financial power of attorney under GOL §5-1513 handles money, property, and legal matters — but it has no authority over medical care. That job belongs to your health care proxy under Public Health Law Article 29-C, which appoints an agent to make medical decisions when you cannot. Your will directs what happens to your probate assets at death, while a trust can move assets outside of probate entirely. For a full picture of how the pieces interlock, see our estate planning overview.
The Baseline Rule: Review Every 3–5 Years
Even if nothing dramatic happens in your life, schedule a review of all four documents at least every three to five years. Laws change, your assets grow or shift, the people you named may move, fall ill, or fall out of your life — and a document that perfectly matched your circumstances in 2020 may quietly no longer reflect your wishes today.
A periodic review is especially important for two documents:
- Your power of attorney. New York overhauled the statutory short form in 2021. A POA executed before then is generally still valid, but an updated form gives your agent clearer authority and is far less likely to be rejected by a bank or financial institution.
- Your health care proxy. The agent you named years ago may no longer be the right person, or may no longer be reachable. Confirm your primary and alternate agents are still willing and able to serve.
Life Events That Demand an Immediate Update
Do not wait for the next scheduled review when one of these happens. Each event can render part of your plan ineffective — or worse, send your assets somewhere you never intended.
Marriage or Divorce
A new spouse changes everything about how your estate is distributed and taxed. Conversely, a divorce should trigger a full rewrite. Under New York law certain dispositions to a former spouse are revoked by divorce, but you should never rely on the statute to do your editing for you — update your will, trust, POA, and health care proxy by name so an ex-spouse is not left holding authority over your money or your medical care.
Birth or Adoption of a Child or Grandchild
A will is where New York parents name a guardian for minor children — there is no more important reason to have one. New children also mean new beneficiaries and, often, a trust to manage assets until they are old enough to handle them responsibly.
A Death in the Family
If a beneficiary, executor, trustee, agent, or guardian named in your documents has died, those roles must be reassigned. An estate plan with a deceased executor or a deceased health care agent and no named alternate can stall exactly when your family needs it to work.
A Significant Change in Assets or a Move
Buying a home, selling a business, receiving an inheritance, or relocating across state lines all reshape your plan. If you move to New York from another state, have your documents reviewed for New York compliance — particularly your will’s execution under EPTL §3-2.1 and your POA’s conformity with the 2021 statutory form.
When the Tax Law Changes: New York Estate Tax in 2026
Tax thresholds shift, and they can pull your plan out of alignment without you doing anything at all. For New York residents this is one of the most important reasons to keep your plan current.
For deaths on or after January 1, 2026 through December 31, 2026, the New York basic exclusion amount is $7,350,000. But New York has a feature that catches many families off guard: the “cliff.” If your taxable estate exceeds 105% of the exclusion — $7,717,500 — you lose the entire exemption and your estate is taxed from the very first dollar, at progressive rates from 3% to 16%.
That cliff is precisely why coordination matters. New York has no gift tax, but any gifts made within three years of death are added back into your taxable estate. An estate that sits near the threshold may be pushed over the cliff by an asset that grew in value or a late gift that gets clawed back. Strategic planning — often using an irrevocable trust, which can reduce the taxable estate, provide asset protection, and support Medicaid planning (subject to the 5-year look-back) — can keep an estate on the right side of the line. A revocable living trust, by contrast, avoids probate but offers no estate-tax savings, so do not assume your trust is doing tax work it was never designed to do.

How the Pieces Fit Together — and Why Updating One Affects the Others
This is the heart of a complete review. The documents are not silos:
- Your trust funding must match your will. If you create a revocable trust to avoid probate but never retitle your accounts and property into it, those assets pass under your will and through probate anyway. Every update to your asset picture is also an update to your trust funding.
- Your POA should be able to fund your trust. A well-drafted durable power of attorney empowers your agent to transfer assets into your trust if you become incapacitated — so an outdated POA can leave your trust half-empty.
- Your beneficiary designations override your will. Life insurance, retirement accounts, and “transfer-on-death” assets pass by designation, not by your will. Reviewing your will without reviewing these designations is only half a review.
When you change one document, walk through the others. That is what “complete” estate planning means — and it is why a coordinated review with an attorney beats patching one document in isolation. For New York–specific rules statewide, see our New York statewide guide.
Frequently Asked Questions
How often should I update my estate plan if nothing has changed?
Review all four documents at least every three to five years. Tax laws and financial institution practices change even when your personal life does not — and your 2021-era power of attorney or older health care proxy may benefit from a refresh.
Does getting divorced automatically remove my ex-spouse from my will in New York?
Divorce revokes certain dispositions to a former spouse under New York law, but you should never rely on that alone. Affirmatively update your will, trust, power of attorney, and health care proxy so your ex-spouse holds no role over your money or medical care.
Will a revocable living trust lower my New York estate tax?
No. A revocable living trust avoids probate but provides no estate-tax savings. To reduce a taxable estate — especially one near the 2026 cliff of $7,717,500 — an irrevocable trust and lifetime planning are the appropriate tools.
What happens if my power of attorney is from before 2021?
A pre-2021 POA is generally still valid, but New York revised the statutory short form in 2021. An updated form under GOL §5-1513 gives your agent clearer authority and is far less likely to be rejected by a bank.
