Life changes faster than the paper in your safe-deposit box. You get married or divorced, a child is born, an executor moves away, a charity closes its doors, or your assets simply grow. When that happens, the question we hear most often at Morgan Legal Group is not whether to update a will — it’s how much it costs and how long it takes. This guide answers both, plainly, for anyone across New York State: New York City, Long Island, Westchester, the Hudson Valley, and Upstate.
A codicil is a separate legal document that amends an existing will without replacing it. Done correctly, it’s a fast, surgical fix. Done sloppily, it’s a slow-motion problem that surfaces only after you’re gone — when it’s too late to correct. The difference is almost entirely about execution formalities, which is where most of this page focuses.
What a Codicil Actually Is (and Isn’t)
A codicil is an amendment. It references your original will, changes one or more specific provisions, and leaves everything else intact. Think of it as an addendum to a contract rather than a brand-new contract.
Here’s the part that trips people up: under New York law, a codicil must be signed and witnessed with the same formality as the will itself. There is no “lighter” process for an amendment. A handwritten note clipped to your will, an email to your attorney, or a marked-up copy of the old document does not amend anything. Those are wishes, not instruments.
A codicil is also not a living will. A living will is a health-care directive about end-of-life medical treatment — it has nothing to do with distributing property. People conflate the two constantly because of the shared word “will.” If your goal is to change who inherits what, who serves as executor, or how a bequest is structured, you need a codicil (or a new will), not a health-care document.
How a Codicil Must Be Executed in New York
New York will execution is governed by EPTL §3-2.1, and the same rules apply to codicils. Skip a step and the amendment can fail in Surrogate’s Court. Here is the full checklist:
| Requirement | What It Means in Practice |
|---|---|
| Signature at the end | You (the testator) must sign at the end of the codicil. Anything written below your signature may be disregarded. Another person may sign for you, but only in your presence and at your direction. |
| Two attesting witnesses | At least two witnesses must attest. Best practice is to use witnesses who are not beneficiaries. |
| 30-day window | Both witnesses must sign within one 30-day period. The law presumes (rebuttably) this requirement is met when the codicil is properly dated. |
| Publication | You must declare to the witnesses that the document is a codicil to your will. They don’t need to read it — they need to know what it is. |
| Signing or acknowledgment | You either sign in each witness’s presence, or you acknowledge your earlier signature to each of them. |
| Witness addresses | Each witness signs at your request and adds their residence address. |
If that list looks familiar, it should — it mirrors the rules on our will execution and NY will requirements pages. The takeaway: a two-paragraph codicil demands the exact same signing ceremony as a 40-page will. That single fact drives almost every cost-and-timeline decision below.
Codicil vs. New Will: The Practical Cost-and-Timeline Tradeoff
Because the execution effort is identical whether you amend or rewrite, the real question is which approach produces a cleaner document and less work — for you now and for your executor later.
A codicil tends to make sense when:
- The change is small and self-contained (swapping one executor, adjusting a single dollar bequest, adding one beneficiary).
- Your underlying will is recent and otherwise accurate.
- You want a documented trail showing a deliberate, narrow change.
A new will tends to make sense when:
- You’re making several changes, or changes that ripple through multiple clauses.
- Your will is old and the foundational language needs modernizing anyway.
- A major life event (marriage, divorce, a new child) reshapes your whole plan.
- You’ve already executed one or two codicils — stacking amendments invites confusion.
Here’s the trap with codicils: every codicil creates another document your executor must locate, prove, and submit to probate. A will plus three codicils means four instruments, four signing ceremonies to validate, and four chances for a witness to be unavailable years later. Often the simpler path — and the one that saves your estate time and aggravation — is a fresh will that revokes the old one entirely. We walk through that decision on our will drafting overview.
A Realistic Timeline
For a straightforward codicil, the working timeline usually looks like this:
- Consultation (1 meeting): We confirm what’s changing and whether a codicil or a new will is the right tool.
- Drafting (days, not weeks): A narrow codicil is quick to prepare once the change is defined.
- Execution (one appointment): The signing ceremony — testator plus two witnesses — typically takes under an hour when properly supervised.
- Storage: The codicil is stored with the original will. A codicil separated from its will is nearly useless.
A new will follows the same arc but generally requires more drafting and review time, since the whole instrument is rebuilt. Neither requires any court filing while you’re alive — a will and its codicils take effect only at death and are submitted to Surrogate’s Court for probate then, not before.
A Note on Cost
We won’t quote a fixed fee on a public page, because cost depends on complexity — a one-line executor change is not the same as a multi-clause restructuring. But the cost driver is predictable: it’s the drafting and review work, plus the supervised signing. The execution ceremony itself costs the same effort whether you amend or rewrite. When the changes are extensive, a new will is frequently the better value because you avoid a document graveyard of stacked codicils. We give you a straight answer at the consultation.
What Happens If You “Amend” Your Will Incorrectly
This is where DIY edits do real damage. A few common failures:
- Crossing out or writing on the original will. Handwritten interlineations are not a valid amendment in New York and can cast doubt on the entire document.
- An unwitnessed “codicil.” Two attesting witnesses are mandatory. One witness, or none, means the amendment is void.
- Signing in the wrong place. Material added below your signature can be ignored.
- Losing the codicil. If the codicil can’t be found but the will can, your executor may be left with the original terms you tried to change.
The cruelest part is that none of these errors surface until probate, when you can no longer fix them. If a flawed amendment fails and no valid will remains, the estate can fall partly or wholly into intestacy under EPTL Article 4, which distributes property to next of kin by a rigid statutory formula — not according to your wishes. We explain that fallback on our intestacy / no-will page.
The Spousal Share a Codicil Cannot Erase
One limit worth knowing: a codicil cannot quietly disinherit a spouse. Under New York’s right of election (EPTL 5-1.1-A), a surviving spouse may claim a statutory minimum share of the estate regardless of what the will or any codicil says. So if your amendment reduces a spouse’s inheritance, the right of election may still override it. Plan around that reality rather than against it — a point we always raise during drafting.

Frequently Asked Questions
How many witnesses does a codicil need in New York?
At least two attesting witnesses, exactly as a will requires under EPTL §3-2.1. Both must sign within one 30-day period, and each adds their residence address. A one-witness or unwitnessed codicil is invalid.
Can I just handwrite a change on my existing will?
No. Crossing out a line or writing in the margin of your original will is not a valid amendment in New York and may raise doubt about the whole document. A proper codicil is a separately executed instrument signed at the end and witnessed by two people.
Is a codicil cheaper than writing a new will?
Sometimes, but not always. The signing ceremony requires the same formality either way, so the cost difference comes down to drafting. For a single narrow change a codicil is usually quicker; for several changes a fresh will often costs less aggravation and avoids stacking multiple documents your executor must prove.
Does a codicil get filed with a court while I’m alive?
No. A will and its codicils take effect only at death and are submitted to Surrogate’s Court for probate then. Nothing is filed during your lifetime; the documents stay in safe storage.
Can a codicil disinherit my spouse?
Not entirely. New York’s spousal right of election (EPTL 5-1.1-A) lets a surviving spouse claim a minimum statutory share regardless of the will or codicil. We plan around this when an amendment changes a spouse’s share.
