Free Codicil to a Will Template – How to Amend Your Will

Update Your Will Without Rewriting It

Your will from a few years ago still mostly holds up, but one thing has changed. Maybe you welcomed a grandchild, sold the lake house, or lost touch with the cousin you named as executor. You don’t need to tear up the whole document and start over. You need a codicil: A short, legally recognized amendment that updates specific parts of your existing will while leaving everything else intact.

Below you’ll find a free, copy-and-paste codicil template (plus Word and PDF downloads), plain-English signing instructions, and the witnessing rules that actually make it valid in your state. Used correctly, a codicil costs nothing and takes about fifteen minutes. Used carelessly, it can quietly undo part of the plan you meant to protect, so this guide also covers the traps.

What Is a Codicil?

A codicil is a separate legal document that modifies, adds to, or revokes part of an existing will. It doesn’t replace your will; it rides alongside it. When you die, the probate court (the court that carries out wills) reads the original will and the codicil together as one combined set of instructions, with the codicil controlling anywhere the two conflict.

Because a codicil changes who gets what, the law treats it with the same seriousness as the will itself. It generally must be signed and witnessed using the same formalities your state requires for a will. A note in the margin of your will or a marked-up photocopy won’t survive a challenge, and it can cast doubt on provisions you never meant to touch.

Key concept: Republication. A valid codicil “republishes” your will, which is the legal way of saying the law now treats your will as if it were re-signed on the day you executed the codicil. That sounds harmless, and often it helps, because it confirms the will still reflects your wishes. But re-dating your will can have side effects nobody warns you about. There’s a full section on this trap below, because it’s the part of codicil law most likely to hurt a family.

You can also undo a codicil later: Deliberately destroy it, sign a later codicil that revokes it, or sign a new will. Revoking the underlying will generally revokes its codicils along with it.

Codicil or New Will? How to Decide

Big life changes sometimes move your estate across a state tax threshold too; the current lines are in our estate tax by state table.

Codicils shine for small, surgical changes. They’re a poor fit for major overhauls. Here’s how to tell the difference.

A codicil makes sense when you want to:

• Change your executor, or name a backup executor
• Add or remove one specific gift (“I leave my grandmother’s ring to my niece, Hannah”)
• Update a beneficiary’s legal name after a marriage or divorce
• Adjust a dollar amount or percentage left to someone
• Name a new guardian for a minor child
• Correct a typo or an outdated address

Write a new will instead when you’re facing:

• A divorce or remarriage that reshapes your whole plan
• The birth or adoption of a child who isn’t mentioned anywhere (see the republication trap before you touch a codicil in this situation)
• A large change in assets, like selling a business or receiving an inheritance
• More than two or three separate amendments piling up
• A move to a new state with different probate rules

The reason is practical: Multiple codicils stacked on an old will create a confusing paper trail. Each amendment is one more document a probate court must locate, authenticate, and reconcile, and probate delays cost real money (our probate cost estimator shows how quickly fees add up). When the changes get big or numerous, a clean new will that revokes all prior wills and codicils is safer and easier for your family to administer. If you’re starting fresh, our free last will and testament template walks through the whole document.

One distinction that trips people up: A codicil amends a will. If your estate plan is built around a revocable living trust, you update it with a trust amendment instead, which has its own rules; see our living trust amendment template. And if you’re weighing whether to move from a will to a trust entirely, start with our living trust vs. will cost breakdown.

Free Codicil Template (Copy and Paste)

Replace every bracketed item with your own information, delete the amendment blocks you don’t use, and read the signing instructions in the next section before anyone picks up a pen. The downloadable versions above match this text.

Before you fill it in: Use full legal names everywhere, quote the exact article or paragraph numbers from your will, and write “Second Codicil” or “Third Codicil” if you’ve amended before. If a child has been born or adopted since you signed your will, stop and read the republication section first.

How to Fill Out and Sign Your Codicil (Step by Step)

The signing ceremony is where most do-it-yourself codicils succeed or fail. Follow these steps in order.

Step 1: Pull Out Your Original Will

You’ll need its exact execution date and the article or paragraph numbers you intend to change. Read the sections you’re amending so your new language fits the will’s existing structure and defined terms.

Step 2: Write Each Change Precisely

Reference the provision, then state the change. For example: “I revoke Article IV, Paragraph 2 of my Will in its entirety and replace it with the following: I give my 2019 Toyota Highlander to my son, Daniel Reyes.” Avoid vague phrases like “most of my savings”; courts can’t enforce what they can’t measure.

Step 3: Leave Everything Else Alone

Don’t restate provisions you’re not changing. The republication clause already keeps them alive. Re-typing them only creates opportunities for inconsistency.

Step 4: Sign in Front of Two Witnesses

Nearly every state requires two witnesses who watch you sign (or hear you acknowledge your signature) and then sign themselves. Some states add their own wrinkles: In California both witnesses must be present at the same moment and must sign during your lifetime, in Florida you and both witnesses sign in one another’s presence, and in New York both witnesses must sign within a single 30-day window. The safest ceremony everywhere: Everyone in one room, phones down, all signatures in one sitting.

Step 5: Make It Self-Proving Where Your State Uses That

In most states you can attach a self-proving affidavit: A short notarized statement, signed by you and both witnesses, swearing the ceremony was done correctly. It isn’t required for validity, but it lets the court accept the codicil without tracking down your witnesses years later. California is the notable exception: It doesn’t use notarized self-proving affidavits, because a signed attestation clause (the paragraph above the witness signatures) plus one witness’s later affidavit does the same job under Probate Code §8220.

Step 6: Store the Codicil With the Will

Physically keep the codicil with the original will, and tell your executor where both live. A codicil nobody can find does nothing. While you have the file open, it’s a good moment to confirm your other documents are current too, starting with your medical power of attorney and healthcare directive.

Who Can Witness a Codicil?

Any competent adult generally qualifies (Texas allows witnesses as young as 14). The person who matters is the one you should not use: Anyone who inherits under the will or codicil, called an “interested witness.” What happens if a beneficiary witnesses anyway varies more by state than almost any other codicil rule:

The rule of thumb that works in all 50 states: Pick two adults who get nothing under the will or codicil and aren’t married to anyone who does. Neighbors, coworkers, or friends are ideal. Even in Florida, where the statute forgives it, an interested witness hands a will contest its opening argument.

State Codicil Signing Requirements (2026)

Codicils follow your state’s rules for executing a will. Here are the four most-searched states, verified against the statutes in mid-2026, plus the general rule everywhere else. A “holographic” codicil means one written entirely in your own handwriting.

When in doubt, over-comply: Two disinterested adult witnesses, everyone signing in one sitting, plus a self-proving affidavit where your state uses one. Extra formality never invalidates a codicil; missing formality does.

The Republication Trap Most Templates Never Mention

Here’s the detail I most want parents and grandparents to hear before signing anything. When you execute a codicil, the law treats your entire will as re-signed on the codicil’s date. Lawyers call this “republication by codicil.” Usually it’s harmless. In one situation it’s devastating.

Every state protects children who are born or adopted after a will was signed and were never mentioned in it. The law calls them “omitted” or “pretermitted” children, and it typically gives them an automatic share of the estate on the theory that the parent forgot to update the will, not that they meant to disinherit their child. California’s version, Probate Code §21620, states the timing rule plainly: The protection covers a child born or adopted after the execution of all of the decedent’s testamentary instruments. A codicil is a testamentary instrument.

Now walk through what that means. You sign a will, then have a baby, then sign a codicil that does something unrelated, like swapping your executor. The codicil re-dates your will to a day when your child was already alive. Your child is no longer “born after the will,” so the automatic protection evaporates, and if the will never mentions them, they can end up with nothing. A Florida appellate court reached exactly that result in Azcunce v. Estate of Azcunce (1991): a daughter born between the will and a later codicil lost her statutory share because the codicil republished the will after her birth.

The protective rule is easy: If any child has been born or adopted since you signed your will, don’t sign a codicil that ignores them. Either provide for them (or intentionally address them) in the codicil itself, or skip the codicil and sign a new will that reflects your family as it exists today.

Republication has friendlier uses too. Because the codicil re-dates the will, it can reaffirm your wishes after a life event that might otherwise invite a challenge, and in some states it can cure certain technical defects in the original document. If you think you need republication to fix a broken will, though, that’s a conversation for a probate attorney, not a template.

Codicil vs. New Will vs. Online Service: What Should You Use?

There’s no single right answer; it depends on how complex your change is and how much guidance you want. Here’s an honest cost and fit comparison.

If your change is genuinely simple, the free template does the job. If you’d rather answer plain-English questions and have the document adapt to your state’s rules automatically, a guided builder is a low-cost middle ground. And if your estate involves a business, a trust, or potential family conflict, pay for an attorney; the fee is small next to the cost of a will contest.

Common Codicil Mistakes to Avoid

Mistake 1: Editing the Will Itself

Handwriting a change in the margin of your will or crossing out a line usually accomplishes nothing, and it can raise questions about the whole document. Execute a separate, properly witnessed codicil instead.

Mistake 2: Using a Beneficiary as a Witness

As the table above shows, New York voids the gift and California presumes wrongdoing. Two disinterested adults are always available somewhere; use them.

Mistake 3: Vague Language

“I want my daughter to have a little more” means nothing in probate. State the exact gift, the person’s full legal name, and the exact provision you’re changing.

Mistake 4: Losing the Original Will

A codicil amends a specific will. If the original can’t be found, your codicil may have nothing to attach to, and a court may presume a missing will was revoked. Keep them together and tell your executor where they are.

Mistake 5: Stacking Too Many Codicils

By the third amendment you’ve built a puzzle for the probate court, and every extra document is another thing to authenticate. If you keep changing the same will, stop and write a fresh one that revokes everything before it.

Mistake 6: Expecting a Codicil to Change Non-Probate Assets

Life insurance, 401(k)s, IRAs, and payable-on-death bank accounts pass by beneficiary designation, outside your will entirely. No codicil can redirect them. Update those beneficiary forms directly with the insurer, plan administrator, or bank. The same goes for assets you’ve retitled into a revocable living trust: They follow the trust document, not the will.

Frequently Asked Questions

Is a codicil legally binding?

Yes. As long as it’s executed with the same formalities your state requires for a will, generally your signature plus two disinterested witnesses, a codicil carries the same legal weight as the will it amends.

Do I need a lawyer to write a codicil?

No. For a simple change like updating an executor or adding a single gift, a clearly written template signed and witnessed correctly is enough. Bring in an attorney if your estate is large, involves a trust or business, a child was born after your will was signed, or you expect anyone to challenge the change.

Does a codicil need to be notarized?

Not for validity in most states; witnesses are what make it binding. A notary comes in for the optional self-proving affidavit, which speeds up probate. California is different: It relies on the signed attestation clause instead of notarized affidavits.

Can a codicil be handwritten?

In states that recognize holographic wills, such as California and Texas, a codicil written entirely in your own hand can be valid without witnesses. Florida rejects unwitnessed handwritten codicils, and New York allows them only for active-duty military and mariners at sea. A typed, witnessed codicil is the safe choice everywhere.

Can I sign a codicil electronically?

Only in the minority of states that authorize electronic wills, such as Florida under Fla. Stat. §732.521 and following, and those laws impose strict electronic-witnessing rules. Most states still require ink on paper. Unless your state clearly allows electronic execution, print it and sign it.

How many codicils can I add to a will?

There’s no legal limit, but two or three is the practical maximum. Beyond that, the stack of amendments becomes hard to read and easy to contest. At that point, replace the will entirely.

What happens if my codicil conflicts with my will?

The codicil controls. As the more recent expression of your wishes, it governs wherever it contradicts the will, and the will governs everywhere else.

Can a codicil change the beneficiary on my life insurance or 401(k)?

No. Those assets pass by beneficiary designation outside the will, so a codicil has no effect on them. Change the designation form directly with the insurance company or plan administrator.

Amend Your Will the Right Way

Life changes, and a will that no longer matches your life puts the people you love in the position of guessing what you meant. A codicil lets you make a precise update without starting over, provided you word the change clearly, sign it with two disinterested witnesses, and watch for the republication trap if your family has grown. Copy the template above or download the fillable version, follow the signing steps, and store the codicil with your original will. Fifteen careful minutes now is a genuine kindness to the people who’ll rely on that document later.
