Life rarely stands still. You marry, you welcome a child or grandchild, you buy a home, you sell a business, you lose a loved one, or you simply change your mind about who should inherit what. When any of that happens, the will you signed years ago may no longer say what you want it to say. In New York, you generally have two ways to fix that: you sign a codicil (a formal amendment to your existing will) or you execute an entirely new will that replaces the old one.
At Morgan Legal Group, attorney Russel Morgan, Esq. and our team prepare codicils, will restatements, and the full range of estate-planning instruments for clients across New York State — from Manhattan, Brooklyn, and Queens to Long Island, Westchester, the Hudson Valley, and Upstate. This page focuses on amendments, but a codicil rarely lives alone. It sits inside a larger document set, and getting the whole set right is what keeps a plan from unraveling in the Surrogate’s Court.
What Is a Codicil?
A codicil is a separate legal document that changes, adds to, or revokes part of an existing will without throwing out the entire will. Think of it as an amendment rather than a rewrite. A short codicil might change a single executor, add a new beneficiary, increase a specific bequest, or remove a gift to someone who has passed away.
Here is the part many people miss: a codicil must be executed with the exact same formalities as the will itself. Under New York’s Estates, Powers and Trusts Law (EPTL §3-2.1), an amendment carries no more legal weight than a sticky note unless it is signed and witnessed the same way an original will is. You cannot simply cross out a line, write in a margin, or initial a change and expect it to hold up. Handwritten edits on the face of a signed will are, at best, ignored and, at worst, evidence that the document was tampered with.
The Document Suite Morgan Legal Group Prepares
Because a codicil is only one piece of a larger plan, it helps to see the full breadth of what we draft. A well-built New York estate plan usually includes several coordinated instruments, and amending one often means reviewing the others.
| Document | What It Does | When You Amend It |
|---|---|---|
| Last Will & Testament | Directs who inherits your property at death; takes effect only at death and must be probated. | New will or codicil |
| Codicil | Amends specific provisions of an existing will. | The amendment itself |
| Living Will | A health-care/end-of-life directive — not a property will. | Replace or re-sign |
| Health-Care Proxy | Names who makes medical decisions if you cannot. | Replace and re-sign |
| Power of Attorney | Authorizes someone to handle financial matters. | Revoke and re-sign |
| Revocable / Irrevocable Trust | Holds and distributes assets, often outside probate. | Trust amendment |
Notice the deliberate separation between a last will and a living will. They share a word but do completely different jobs. A last will distributes your property after death and is admitted to probate; a living will speaks while you are alive and addresses medical care and end-of-life wishes. We never conflate the two, and a “codicil” only ever amends the property will.
When a Codicil Makes Sense — and When It Does Not
A codicil is the right tool for small, surgical changes to a will that is otherwise sound:
- Naming a new executor or alternate executor
- Adjusting a specific dollar bequest or a particular gift of property
- Adding or removing a single beneficiary
- Updating a guardian nomination for minor children
- Correcting a misspelled name or a minor clerical reference
A codicil is the wrong tool when the changes are broad. If you are remarrying, restructuring how your entire residuary estate is divided, adding trusts, or reacting to a major life or financial change, layering multiple codicils onto an old will creates confusion. Each codicil must be read together with the original will and every prior codicil, and inconsistencies invite challenges. In those situations, our will-drafting team almost always recommends a fresh will that revokes all prior wills and codicils, so a single clean document governs.
A practical rule of thumb
One change to one provision: a codicil is usually fine. Two or more substantive changes, or anything touching the core distribution plan: start over with a new will. The drafting fee for a clean restatement is often money well spent compared to litigation over a stack of conflicting amendments.
How a Codicil Must Be Executed in New York
Because a codicil rises or falls on its formalities, the execution rules under EPTL §3-2.1 deserve a careful walk-through. The same requirements apply whether you are signing your first will or your third codicil.
- At least two attesting witnesses are required. New York demands a minimum of two witnesses for both wills and codicils.
- Both witnesses must sign within one 30-day period. When they do, the law presumes the 30-day requirement was satisfied — a rebuttable presumption that protects properly executed documents.
- The testator must sign at the end of the codicil. (If you are physically unable to sign, another person may sign for you, but only in your presence and at your direction.)
- You must declare the document to be a codicil to your will — this is the act of publication. The witnesses need to understand they are witnessing your will amendment.
- You either sign in front of the witnesses or acknowledge your signature to each of them, and the witnesses then sign at your request and add their residence addresses.
For a deeper look at these mechanics, see our pages on New York will requirements and the will execution ceremony. The takeaway is simple: a codicil signed casually, without two witnesses and proper publication, is not a valid amendment — and a defective amendment can cast doubt on the entire will it was meant to improve.
What Happens If You Do Nothing — or Do It Wrong
Two failure modes are worth naming.
Failing to update at all. Your will speaks at the moment of death, not at the moment you intended to make changes. If you meant to add a grandchild but never executed the amendment, that intention has no legal force. And if you have no valid will at all, New York’s intestacy statute (EPTL Article 4) decides who inherits — distributing your estate to your next of kin by a fixed formula that may not match your wishes. Our intestacy overview explains how that default distribution works and why so many families want to avoid it.
Updating it improperly. A codicil that is missing a witness, not signed at the end, or never published is vulnerable. If it is rejected during probate, the court may fall back on the prior will, leaving you with an outcome you specifically tried to change.
There is also a backstop your codicil cannot override: New York’s spousal right of election under EPTL 5-1.1-A. A surviving spouse is entitled to claim a statutory minimum share of the estate regardless of what the will or any codicil says. If your amendment attempts to disinherit a spouse, the right of election still applies. We plan around this reality rather than fighting it.
Probate: Why Clean Documents Matter
A will — and every codicil attached to it — takes effect only at death and must be admitted to probate in the Surrogate’s Court. During probate, the court examines whether each instrument was properly executed. A tidy will with one well-drafted, properly witnessed codicil moves through far more smoothly than a will weighed down by several amendments of uncertain validity. Every defect is a potential opening for an objection. The breadth of documents we prepare exists precisely so that your plan presents to the court as one coherent, defensible whole.
How Morgan Legal Group Approaches Amendments
We do not draft a codicil in a vacuum. When you ask us to change a will, we:
- Review the existing will and any prior codicils to confirm the amendment will be internally consistent.
- Decide codicil vs. new will based on the number and scope of changes.
- Check the surrounding documents — power of attorney, health-care proxy, living will, and any trusts — so the whole plan stays aligned.
- Supervise execution so the EPTL §3-2.1 formalities are met exactly.
- Confirm safe storage and recommend telling your named executor where the documents live.

Frequently Asked Questions
Can I just write the changes on my existing will?
No. Handwritten edits, cross-outs, or margin notes on a signed New York will are not valid amendments. Any change must be made through a codicil or a new will, executed with the full formalities of EPTL §3-2.1, including at least two attesting witnesses.
How many witnesses does a codicil need in New York?
The same number a will needs: at least two attesting witnesses. Both must sign within a single 30-day period, and they should add their residence addresses when they sign at your request.
Is a codicil better than writing a brand-new will?
It depends on the scope. A codicil suits one small, surgical change. For multiple substantive changes — or anything touching how your whole estate is divided — a fresh will that revokes prior wills and codicils is usually cleaner and less vulnerable to challenge in the Surrogate’s Court.
Can a codicil disinherit my spouse?
Not entirely. New York’s spousal right of election under EPTL 5-1.1-A lets a surviving spouse claim a statutory minimum share regardless of what your will or codicil says. We plan around this rule rather than attempting to override it.
What happens to my estate if I never make a valid will or codicil?
If you die without a valid will, New York’s intestacy law (EPTL Article 4) distributes your property to your next of kin by a fixed statutory formula — which may not reflect your wishes. Executing a valid will, and keeping it current through proper amendments, is the only way to control that outcome.
