What Is a Last Will And Testament Codicil?
A Last Will And Testament Codicil in the United States amends an existing will, changing specified gifts or appointments while leaving the rest of the will intact.
The codicil has been a recognized instrument in Anglo-American law for centuries, allowing testators to make targeted changes to their estate plans without the time and expense of drafting an entirely new will. When a codicil is probated, it is read together with the original will as a single integrated document. Any provisions in the codicil that conflict with the original will supersede the earlier terms, while all non-conflicting provisions of the original will remain in full effect.
note that a codicil effectively "republishes" the original will as of the codicil's date. Under UPC Section 2-509, this republication can have practical consequences -- for example, if a beneficiary named in the original will predeceased the testator but a new beneficiary is alive on the codicil date, the republication may resolve certain lapse issues. Estate planning attorneys generally recommend limiting codicils to minor changes; if extensive revisions are needed, drafting a new will with a revocation clause is typically more reliable and less likely to create ambiguity during probate.
When Do You Need a Last Will And Testament Codicil?
A codicil is appropriate when you need to change the executor or alternate executor named in your will -- for instance, if your original executor has passed away, become incapacitated, moved out of state, or you simply prefer a different person for the role.
If you want to update a specific bequest -- such as leaving a piece of jewelry to a different family member or changing the dollar amount of a charitable gift -- a codicil allows the targeted change without disturbing the rest of your estate plan.
After a life event such as the birth of a grandchild, you may want to add a new beneficiary. A codicil can insert the new provision without requiring you to redistribute all other bequests. Similarly, if a named beneficiary passes away and you want to redirect their share, a codicil handles this efficiently.
Changing the guardian designated for minor children is another common reason. If your chosen guardian is no longer willing or suitable, a codicil names the replacement while keeping all other provisions intact.
However, a codicil is not recommended for substantial restructuring of your estate plan, changes to trusts established under your will, or situations where multiple prior codicils already exist. Multiple codicils attached to a single will can create confusion and increase the risk of probate challenges. In those cases, executing a completely new will is the safer approach.
What to Include in Your Last Will And Testament Codicil
The codicil must open with a declaration identifying the testator by full legal name, stating the date of the original will being amended, and confirming that the testator is of sound mind and acting voluntarily. This mirrors the testamentary capacity requirements under state probate codes.
A specific reference to each provision being amended is essential. Rather than restating the entire will, the codicil should identify the exact article, section, or paragraph number being changed and state the new language that replaces or supplements it. Vague references -- such as "I change my bequests" without specifying which ones -- invite probate challenges.
A ratification clause must confirm that all provisions of the original will not expressly modified by the codicil remain in full force and effect. This prevents any argument that the codicil impliedly revoked other portions of the will.
Witness requirements must match those of the original will. Most states require two disinterested witnesses (persons who are not beneficiaries) who observe the testator's signature and sign the codicil themselves. Under UPC Section 2-502, witnesses must be present at the same time in many jurisdictions. Louisiana uniquely requires notarized form for all testamentary instruments under its Civil Code.
A self-proving affidavit, signed before a notary public by the testator and witnesses, eliminates the need to locate witnesses during probate to authenticate the codicil. This is authorized under UPC Section 2-504 and adopted in the vast majority of states.
The codicil should be stored with the original will -- physically attached if possible -- to confirm both documents are found and presented to the probate court together. The testator should note the codicil's existence in any letter of instruction provided to the executor.

Frequently Asked Questions
A Last Will And Testament Codicil is valid when the testator is at least 18, of sound mind, acts free of undue influence, and executes the document with the formalities the governing state requires. The Uniform Probate Code and state law treat testamentary capacity as the ability to understand the nature of making a will, the property owned, and the people who would normally inherit. The Last Will And Testament Codicil should clearly identify the testator, revoke prior wills, name beneficiaries and an executor, and be signed and dated in the presence of the required witnesses. Storing the original in a safe and accessible place matters, because many states will admit only the original signed Last Will And Testament Codicil to probate, and a lost original can raise a presumption that the testator revoked it. Reviewing and updating the document after marriage, divorce, births, or major asset changes keeps it aligned with current law and the testator's intent.
A Last Will And Testament Codicil must be witnessed in almost every US state to be valid, and the formalities are stricter than for ordinary contracts. The Uniform Probate Code (UPC § 2-502) and most state statutes require the testator to sign in the presence of two competent witnesses who also sign, and the witnesses generally should not be beneficiaries to avoid having their gifts voided under interested-witness rules. Notarization is not required to make a Last Will And Testament Codicil valid, but adding a self-proving affidavit signed before a notary lets the probate court accept the document without later locating the witnesses. A handful of states recognize holographic (handwritten) wills with fewer formalities, but relying on that exception is risky. A Last Will And Testament Codicil that is not witnessed according to the governing state's rules can be denied probate entirely, causing the estate to pass under intestacy law instead of the testator's stated wishes.
A Last Will And Testament Codicil does not avoid probate; instead, it directs how the probate court should distribute the estate. Probate is the court-supervised process of validating the document, paying debts and taxes, and transferring remaining assets to the named beneficiaries, and most estates with a will still pass through it. Assets that transfer by operation of law — such as jointly held property, accounts with payable-on-death designations, and life-insurance proceeds with named beneficiaries — bypass probate regardless of the Last Will And Testament Codicil. Parties who want to keep more assets out of probate often pair a Last Will And Testament Codicil with a revocable living trust, using a pour-over provision so anything left outside the trust still passes under the will. A clearly drafted Last Will And Testament Codicil that names an executor and provides for debts shortens the probate timeline and reduces the chance of family disputes over who should administer the estate.
A Last Will And Testament Codicil takes legal effect as a testamentary instrument, not as a contract, so the rules of offer, acceptance, and consideration do not apply. Under the Uniform Probate Code (UPC § 2-502) and each state's probate code, a Last Will And Testament Codicil is valid when the testator is at least 18 and of sound mind, signs the document (or directs another to sign in the testator's presence), and the signing is attested by at least two competent witnesses who also sign. No consideration is required and there are no contracting "parties" — a will is a one-sided declaration of how the testator wants property distributed at death. Adding a self-proving affidavit notarized under UPC § 2-504 lets the probate court admit the Last Will And Testament Codicil without calling the witnesses to testify. A Last Will And Testament Codicil that fails the witnessing formalities can be denied probate, so the estate would pass under intestacy law instead of the testator's stated wishes. Store the signed original safely, because many states admit only the original to probate.
A Last Will And Testament Codicil is changed by following testamentary formalities, not contract-modification rules, so there is no "amendment that is itself a contract" and no requirement of fresh consideration. A testator amends a will by signing a codicil — a short document that references the original will and states the changes — executed with the same formalities as the will itself: signed by the testator and attested by at least two competent witnesses under the Uniform Probate Code (UPC § 2-502). For anything beyond a minor change, drafting a new will that revokes the prior one is cleaner and less likely to create ambiguity in probate. The testator can revoke or replace the Last Will And Testament Codicil at any time while alive and of sound mind; no beneficiary's agreement is needed, because a will speaks only at death and binds no living party. Striking through or handwriting edits on the signed original can invalidate gifts or the whole instrument, so changes should be made by a properly witnessed codicil or a new will kept with the original.
A Last Will And Testament Codicil does not require a lawyer in most routine situations, and many individuals and small businesses prepare one using a clear written template that covers the standard terms. American law does not condition the validity of a Last Will And Testament Codicil on attorney involvement; what matters is that the parties understand the terms and sign voluntarily. Legal review becomes worthwhile when the amounts at stake are large, the relationship is complex, the parties are in different states, or the agreement involves unusual conditions, tax consequences, or rights that are difficult to reverse. An attorney can confirm the document complies with the governing state's law and tailor clauses such as indemnification, dispute resolution, and termination. For straightforward matters, a carefully completed Last Will And Testament Codicil from forms-legal.com gives the parties a solid written record; consulting a licensed attorney remains the safer path whenever the consequences of a mistake would be costly or hard to undo.
