Can You Change or Decant an Irrevocable Trust in New York?

Yes — despite its name, an irrevocable trust in New York is not always set in stone. While the general rule under New York’s Estates, Powers and Trusts Law (EPTL) Article 7 is that an irrevocable trust cannot simply be amended or revoked the way a revocable trust can, New York law provides several legitimate paths to change one: full consent of the grantor and all beneficiaries, court modification, and “decanting” (pouring the assets of an old trust into a new, better-drafted trust). The right path depends on whether the grantor is still living, who the beneficiaries are, and what you are trying to fix. This guide walks through your options as a practical checklist so you know exactly what next steps to take.

Why “Irrevocable” Doesn’t Always Mean “Unchangeable”

People create irrevocable trusts for powerful reasons: reducing New York estate tax, protecting assets from creditors, and qualifying for Medicaid long-term care (subject to the 5-year look-back). To deliver those benefits, the grantor must give up control — and that surrender of control is what makes the trust “irrevocable.”

But life changes. Tax law shifts. A beneficiary develops a disability. A named trustee dies, moves, or becomes unsuitable. New York recognizes that a rigid, outdated trust can defeat the very purpose it was meant to serve, so the law builds in escape valves. Learn more about how these vehicles work on our Irrevocable Trust and Trusts Overview pages.

Your Three Main Options to Change an Irrevocable Trust

Method	When It Works Best	Key Requirement
Grantor + beneficiary consent	Grantor is alive; everyone agrees	Written consent of the grantor and ALL beneficiaries (EPTL 7-1.9)
Decanting	Grantor unavailable or some terms need fixing	Trustee has authority to invade principal; new trust drafted (EPTL 10-6.6)
Court modification	Disputes, unborn/minor beneficiaries, or ambiguity	Petition to the court showing good cause

Option 1: Amendment or Revocation by Consent (EPTL 7-1.9)

New York’s EPTL 7-1.9 allows a grantor who is still living to revoke or amend an irrevocable trust if every person beneficially interested in the trust consents in writing. This is the cleanest route — but it has a catch. “All beneficiaries” includes contingent and remainder beneficiaries (for example, grandchildren who would inherit only if a child predeceases). If any one of them is a minor, unborn, or simply refuses, consent alone will not work.

Option 2: Decanting (EPTL 10-6.6)

Decanting is one of New York’s most flexible tools. Under EPTL 10-6.6, a trustee who has the authority to invade trust principal may “pour” the assets of an existing irrevocable trust into a new trust with updated terms — without the grantor’s or beneficiaries’ signatures. Think of it like decanting wine from an old bottle into a fresh one.

Common reasons to decant in New York include:

• Fixing a drafting error or ambiguous language
• Converting a standard trust into a Special Needs Trust to protect a beneficiary’s Medicaid or SSI eligibility
• Changing trustee provisions or adding a trust protector
• Extending the trust’s duration or updating administrative powers
• Adapting to changes in tax law

Decanting is powerful but technical. The trustee must follow statutory notice requirements and act consistently with their fiduciary duties.

Option 3: Court Modification

When beneficiaries cannot all consent — or when there is a genuine dispute — the parties can petition the court. A judge can authorize modification when circumstances have changed in ways the grantor could not have anticipated, or to correct a mistake. This route involves more time and cost but is sometimes the only option when minor or unborn beneficiaries are involved.

Practical Checklist: Your Next Steps

Use this step-by-step checklist before you attempt to change any irrevocable trust:

1. Locate and read the trust document. Identify whether the grantor is living, who the trustee is, and who the beneficiaries (including remainder beneficiaries) are.
2. Define the problem precisely. Are you fixing a typo, changing trustees, adding special-needs protections, or responding to tax changes? The goal determines the method.
3. Check the grantor’s status. If the grantor is alive and cooperative, Option 1 (consent) may be fastest.
4. Identify ALL beneficiaries. Look for minors, unborn, or contingent beneficiaries who cannot legally consent — they often push you toward decanting or court.
5. Confirm the trustee’s powers. Does the trustee have authority to invade principal? That authority is the gateway to decanting under EPTL 10-6.6.
6. Assess tax and Medicaid consequences. Changes can affect the 5-year Medicaid look-back and New York estate tax exposure. New York’s 2026 basic exclusion is $7,350,000, with a “cliff” at 105% — $7,717,500 — above which the entire exemption is lost.
7. Do not act alone. A trustee who modifies a trust improperly may breach their fiduciary duties. See our Trust Administration page.
8. Consult a New York trusts attorney before signing anything.

Trustee Duties Still Apply

Whoever changes the trust must respect the trustee’s fiduciary obligations: the prudent-investor standard (EPTL Article 11-A), the duty of loyalty, and the duty to account to beneficiaries. Decanting or modifying a trust does not suspend these duties — a poorly executed change can expose a trustee to personal liability. This is why irrevocable-trust changes are best handled with experienced counsel rather than do-it-yourself forms.

If your goal is simply to retain control and flexibility going forward, you may be better served by a Revocable Living Trust, which the grantor can amend or revoke at any time — though it does not reduce estate tax, since the assets remain in the taxable estate.

Frequently Asked Questions

Can I change an irrevocable trust in New York without going to court?
Often, yes. If the grantor is alive and every beneficiary consents in writing under EPTL 7-1.9, or if the trustee has authority to decant under EPTL 10-6.6, you may be able to make changes without a court proceeding.

What is “decanting” a trust?
Decanting is the process by which a trustee transfers the assets of an existing irrevocable trust into a new trust with updated terms, authorized in New York by EPTL 10-6.6. It does not require beneficiary signatures.

Will changing my irrevocable trust affect Medicaid eligibility?
It can. Irrevocable trusts used for Medicaid planning are subject to the 5-year look-back, and certain modifications could restart timing or change the asset’s treatment. Always review Medicaid consequences before making changes.

Does an irrevocable trust still avoid probate after it’s modified?
Generally, yes — like other trusts, it avoids the public probate process in Surrogate’s Court and keeps your affairs private. To understand the difference, see our Trust vs. Will page.
