A will is not a document you write once and forget. Life changes — marriages, divorces, new children, new property, a falling-out with a named beneficiary, or simply a change of mind about who should serve as executor. When your circumstances shift, your will should shift with them. In New York, the formal instrument used to change an existing will is called a codicil, and it must be executed with the very same care as the original will under EPTL §3-2.1.
At Morgan Legal Group, attorney Russel Morgan, Esq. and our team draft codicils and complete will revisions for clients across New York State — from New York City and Long Island to Westchester, the Hudson Valley, and Upstate. Amendments are only one piece of a much broader estate-planning practice. This page explains how codicils work in New York, when a fresh will is the smarter choice, and how amendment fits into the full library of documents we prepare for our clients.
Where Codicils Fit in Our Document Library
We are a full-service estate-planning firm, not a single-form shop. Codicils rarely stand alone — they are usually drafted alongside other instruments as part of a coordinated plan. The documents we routinely prepare include:
| Document | Purpose | Related Page |
|---|---|---|
| Last Will & Testament | Directs distribution of property at death; appoints executor and guardians | Will Drafting Overview |
| Codicil | Amends or supplements an existing valid will | Codicils & Amendments |
| Will execution package | Witness attestation, self-proving affidavit, ceremony supervision | Will Execution |
| Living will | Health-care and end-of-life instructions (NOT a property will) | Living Will |
| Trusts & ancillary documents | Probate avoidance, incapacity planning, asset protection | Will Drafting Overview |
When a client comes to us for an amendment, we don’t just fix the one clause — we review the entire plan to make sure the codicil harmonizes with everything else.
What Is a Codicil?
A codicil is a separate legal document that modifies, adds to, or revokes a portion of an existing will without replacing it entirely. Think of it as an official amendment that travels with the original will. Common uses include:
- Changing an executor or naming a successor executor
- Adding or removing a specific bequest (a particular sum, heirloom, or asset)
- Updating a guardian named for minor children
- Adjusting percentages among residuary beneficiaries
- Correcting a name after a marriage, divorce, or legal name change
Because a codicil becomes part of your testamentary plan, it does not take effect until death and must ultimately be admitted to probate in the Surrogate’s Court alongside the will it amends.
Codicils Must Meet the Same Execution Standard as Wills
This is the single most important thing to understand: a codicil is not a casual note. Under EPTL §3-2.1, a codicil must satisfy the identical execution formalities that govern wills. A handwritten margin note, a crossed-out line, or an unsigned letter has no legal force and can jeopardize the entire will.
To be valid in New York, a codicil — like a will — must follow these statutory requirements:
- The testator must sign at the end of the instrument, or another person may sign in the testator’s presence and at the testator’s direction.
- There must be at least two attesting witnesses.
- The testator must declare the instrument to be a codicil to their will (this is called publication).
- The testator must sign in the presence of the witnesses or acknowledge the signature to each of them.
- The witnesses must sign at the testator’s request, adding their residence addresses.
- Both witnesses must sign within a single 30-day period. (New York applies a rebuttable presumption that the 30-day requirement was met.)
When these steps are followed precisely, the law presumes proper execution. When they are skipped or improvised, a disgruntled relative has an opening to challenge the document. Our Will Execution team supervises the signing ceremony so that nothing is left to chance.
Codicil or New Will? How We Decide
A common misconception is that a codicil is always the cheaper, faster fix. Sometimes it is. Often, drafting a clean new will is actually the better path. Here is how we counsel clients:
A codicil may be appropriate when:
- The change is narrow and isolated — swapping one executor, adjusting a single bequest.
- The existing will is otherwise sound and recently drafted.
- The client wants to preserve the original document’s date for a specific reason.
A new will is usually better when:
- There are multiple or substantial changes. Stacking several codicils onto an old will creates a confusing paper trail that invites disputes.
- A marriage or divorce has occurred. New York law treats these life events seriously, and a comprehensive rewrite is cleaner.
- The original will is old, ambiguous, or poorly drafted. A codicil cannot cure structural defects.
- The client wants a fresh self-proving affidavit and an updated, fully integrated document.
In practice, many of our clients who arrive expecting a codicil leave with a new will — and a clearer mind. We explain the trade-offs honestly so the choice is yours. To understand the baseline requirements your amended document must meet, see NY Will Requirements.
How a Codicil Interacts With New York Law
Amendments don’t happen in a vacuum. Several statutory rules shape what a codicil can — and cannot — accomplish:
- Probate is still required. A will (and any codicil) takes effect only at death and must be admitted to probate in the Surrogate’s Court. Amending your will does not change that.
- Intestacy looms if amendment fails. If a botched codicil invalidates your will and no valid prior will survives, your estate may pass under the intestacy rules of EPTL Article 4, which distribute property to next of kin according to a fixed statutory formula — not your wishes. See Intestacy — Dying Without a Will.
- A spouse’s right of election survives any amendment. Under EPTL 5-1.1-A, a surviving spouse may claim a minimum elective share of the estate regardless of what your will or codicil says. No codicil can disinherit a spouse below that statutory floor.
- A living will is not a property document. Clients sometimes ask us to “amend the will” when they really mean updating health-care instructions. A living will is a separate end-of-life and health-care document and is never combined with your property will.
Revoking a Will or Codicil
Amendment sometimes means revocation. A testator may revoke a prior will or codicil — but, here too, the act must be done correctly. Simply tearing up a copy or telling family members “that one’s no good anymore” is risky and frequently litigated. When a new will or codicil is executed, the proper practice is to include an express revocation clause and to manage the original documents carefully. We handle revocation as a deliberate, documented step rather than an afterthought.

Frequently Asked Questions
Does a codicil need witnesses in New York?
Yes. A codicil must be executed with the same formalities as a will under EPTL §3-2.1, which requires at least two attesting witnesses. Both witnesses must sign within a single 30-day period, sign at the testator’s request, and add their residence addresses.
Can I just write changes on my existing will by hand?
No. Handwritten edits, cross-outs, or margin notes on an existing will generally have no legal effect and can cast doubt on the entire document. To change a New York will, you must execute a properly witnessed codicil or a new will.
Is a codicil cheaper or faster than a new will?
Not always. A codicil suits a single, narrow change. When there are multiple or significant changes — or after a marriage or divorce — drafting a clean new will is usually safer and avoids the confusion of stacking amendments. We advise on the best approach for your situation.
Will my codicil still go through Surrogate’s Court?
Yes. A will and any codicil take effect only at death and must be admitted to probate in the Surrogate’s Court. Amending your will does not avoid probate.
Can a codicil disinherit my spouse?
No. Under EPTL 5-1.1-A, a surviving spouse is entitled to a minimum elective share of the estate regardless of what your will or codicil provides. A codicil cannot reduce a spouse below that statutory minimum.
